Definitions
- the invention relates to electronic interface devices and methods of their manufacture, and more particularly, to customized, orthopedic cursor control devices and methods of easily fabricating them to closely conform to the relevant dimensions of an individual.
- the invention relates to for orthopedic electronic interface devices, such as an orthopedic computer mouse, is driven by the variety, and severity, of injuries such as, but not limited to, repetitive stress injuries, that are associated with the prolonged use of conventional computer mice and other conventional electronic interface devices.
- injuries such as, but not limited to, repetitive stress injuries
- the repeated fine motor movements of the hand, wrist and forearm made in operating such conventional devices may result in painful, chronic conditions such as carpal tunnel syndrome, tendonitis, loss of grip strength, Raynaud's phenomenon, Dequervain's disease and trigger finger.
- These repetitive stress injuries are particularly prevalent when the cursor control device requires prolonged use with the hands or wrist in awkward or unnatural positions, or positions that require continuous activation of muscles, or with arthritis or in amputees.
- An orthopedic cursor control device may also be designed to provide stability and to minimize the need for muscle activation when used to control the position of a cursor on a display screen. And in a further embodiment, the orthopedic cursor control device may also maintain a user's hand and wrist at a temperature within a therapeutically desirable range.
- the object of the invention is to avoid injuries by the use of the pointing means for a computer by ensuring that the joints, muscles and tendons of the hand and the arm are not strained unnecessarily in use.
- the pointing means may be constructed so that the thumb engages a recess (6) which is a lengthwise recess (6) with a thumb supporting face (20) having thumb support on a first side (22) and a second opposite side (24) where the recess (6) can have an extension supporting the thumb as well as engagement means (10) for the ball of the thumb. It is ensured hereby that the hand is in a position of rest while the pointing means is operated. The pointing means fills the hand, and the actual movement of the pointing means is performed by the forearm and the wrist. The muscles and tendons of the hand remain in the position of rest during operation of the pointing means. Mouse injuries can be prevented hereby.
- the mouse comprises a bottom surface, a forward end, a rear end, and opposite sides, and a generally hemispherical surface for supporting the fingers of a hand in a generally elevated orientation relative to the support surface with the little finger at a first elevation and the index finger located at a second elevation higher than the first elevation relative to the bottom surface.
- the generally hemispherical surface is further adapted for supporting the hollow of the hand so that the hand rests at an angle with respect to the forearm in the physiological position.
- the general hemispherical finger-supporting surface extends upwardly and laterally from one of the opposite sides.
- a thumb-supporting surface is provided for supporting the thumb of the hand, so that the mouse is securely gripped between the thumb and the fingers, the thumb supporting surface being disposed opposite the generally hemispherical finger-supporting surface.
- U.S. Pat. No. 6,545,665 by Rodgers published on Apr. 8, 2003 entitled “Adjustable computer pointing device” that describes a computer pointing device consists of a adjustable hand support shape and adjustable controls that work together to conform to an individuals natural grip. This allows multiple individual users to shape the device body for their maximum comfort using a squeezing action. A targeted ergonomic configuration allows a user to configure the angle of the hand in the most natural way to minimize twist and strain on the wrist.
- the adjustable structure and button assembly are attached to a flat bottomed base that rests on an underlying flat surface. Attached to the base are the electronic and the mechanical component necessary to provide the required positional and event outputs to a computer.
- U.S. Pat. No. 5,576,733 to Lo published on Nov. 19, 1996 entitled “Ergonomic computer mouse” that describes an ergonomic computer mouse includes an upright, primary finger-supporting surface for supporting all of the fingers of an upright hand in straight positions and in an upright stack. It also includes an opposite thumb-supporting surface for supporting the thumb. A hand holding the ergonomic computer mouse will be in a naturally upright and relaxed position, without requiring twisting of the hand, wrist, or forearm. As a result, fatigue, discomfort, and pain are minimized or eliminated even after a long period of continuous use.
- the present invention is an orthopedic electronic interface device used, for instance, to control a position and function of a cursor on a display screen.
- the device is preferably a computer mouse, but may also be a game controller or a remote control. In other, preferred embodiments, the present invention may also be a foot-controlled user interface.
- the device may be hand operated and perform a control function while supporting a user's hand in a functionally neutral posture.
- the electronic interface device may, for instance, have a motion sensor housed in a base, a mound rigidly attached to the top of the base and a carpal support rigidly attached to the base. Portions of the surfaces of the base, the mound and the carpal support may function together to support a user's hand in a functionally neutral posture.
- the mound of the hand-held electronic interface device may be shaped to closely conform to an interior portion of the user's hand when the user's hand is in a grasping configuration.
- an inner surface of the carpal support may be shaped to closely conform to, and support, the user's wrist in the functionally neutral posture.
- the length of the carpal support may be such that it extends out beyond a distal end of the user's ulna bone when the user grasps the mound of the cursor control device with their hand.
- the functionally neutral posture of the wrist may be that position in which the distal end of the user's radial bone is substantially vertically above the distal end of the user's ulna bone.
- a further embodiment of the invention may include a wrist support rigidly attached to the base.
- the wrist support may extend out from the base to beyond the distal end of the user's ulna bone, and may have an upper surface shaped to support a part of a user's forearm.
- the outer surfaces of the mound of the hand-held cursor control device, the inner surface of the carpal support of the cursor control device and the upper surface of the wrist support of the cursor control device may form a contiguous surface.
- the contiguous surface, or device shell may be shaped to closely conform to a particular user's hand. This is in marked contrast to existing, prior art devices that typically are designed to fit one prototypical sized user hand. Shaping the device to closely conform to a particular user's hand may, for instance, be achieved by a method such as, but not limited to, a molding process that uses a block of malleable material that has been grasped by the user's hand while the user's hand is in a functionally neutral posture.
- the mold, or the user's hand may be turned into suitable numerical data by, for instance, using a 3D optical scanner.
- the suitable numerical data may be feed raw or post-processed to a manufacturing device such as, but not limited to, to a computer controlled milling machine or lathe or 3D printing machine, or some combination thereof.
- Such a method may, for instance, include providing a block of malleable material in the approximate shape of the cursor control device to be produced.
- the person that the custom cursor control device is being prepared for may, with their hand and wrist in the desired functionally neutral posture, grasp the block of malleable material.
- the user may then squeeze the malleable material so that the outer surface of the block assumes the shape of the inner surface of the user's grasping hand.
- the grasped block may then be prepared to function as a molding pattern, and the shell of the cursor control device molded from it, or a suitable 3D scan made of it for use in computer controlled manufacturing devices.
- Yet another object of the present invention is to provide a cursor control device that is closely customized to an individual user.
- Yet another object of the present invention is to provide a cursor control device that may be heated or cooled to a therapeutically desired temperature.
- Still another object of the present invention is to provide a simple method of producing an orthopedic cursor control device.
- Still another object of the present invention is to provide an efficient, and cost effective, method of producing an orthopedic cursor control device that is customized for individual users.

- the user will impart an imprint of the inside surface of their grasping hand and of the surface shape of their hand, wrist and forearm in the functionally neutral posture 115 .
- the grasped block of malleable material 700 may be prepared to be a mold pattern for use in molding the electronic interface device 100 . This preparation will depend to some extent on the molding process and on the material the electronic interface device 100 will be made of.
- the molding process may be any standard process such as, but not limited to, compaction molding, compression molding, blow molding, thermoforming, vacuum forming and injection molding.
- the material used to make the molded electronic interface device 100 thermosetting plastic, a thermoplastic, fiberglass, a polymer, a glass, a ceramic and a plastic.
- the preparation of the grasped block of malleable material to transform it into a suitable mold pattern may include processes such as, but not limited to, removing a portion of the malleable material so as to ensure that a molded device can be easily removed from a mold formed from the molding pattern; adding or removing a layer or a partial layer of a the substantially malleable material so as to compensate for shrinkage or expansion of a the material that will form the molded cursor control device.
- the shrinkage or expansion may be calculated over a temperature change corresponding substantially to a change from a molding temperature of the molding material to approximately room temperature, which is often assumed to approximately in a range from 10 to 30 degrees centigrade, and often in the range of 20 to 25 degrees centigrade.
- a mold may be formed from the mold pattern. This is a well known process and typically involves placing the mold pattern within a frame, and then filling the frame with molten or liquid mold material that will form the mold. When the mold material has cooled, hardened or otherwise set into a mold, the pattern is removed, leaving the mold as a “negative” copy of the mold pattern. Mold materials include, but are not limited to, silicone rubber, urethane rubber, urethane plastic, rigid & flexible foam, epoxy resins and polysulfide rubber.
- the electronic interface device 100 may be made, or “molded”, using the mold formed using the mold pattern.
- This process is often called “casting” and typically involves filling the mold with molten or liquid material that will form the shell of the cursor control device 100 , i.e., a material such as, but not limited to, thermosetting plastic, a thermoplastic, fiberglass, a polymer, a glass, a ceramic and a plastic, or some combination thereof.
- the casting may also involve the use of release agents to help ensure that the casting, or object made by the molding material, may be easily removed from the mold.
- the electronic interface device 100 may be completed, or finished, by, for instance, adding appropriate electronics such as, but not limited to, the motion sensor 320 , the data link 330 and the actuators 510 .
- the step of finishing may also involve machining the hollow, concave cavity 350 to house the motion sensor 320 , and the data link access channel 340 , if these have not been produced in the molding process.

Abstract
An orthopedic cursor control device that supports a user's hand, or other controlling anatomy, in a functionally neutral posture. The device has a motion sensor housed in a base, a mound attached to the top of the base and an optional carpal support attached to the base. The surfaces of the base, mound and optional carpal support together support a user's hand, or other controlling anatomy, in the functionally neutral, or other appropriate, posture. The mound conforms to an interior portion of the user's hand when in a grasping configuration. An inner surface of the carpal support conforms to, and supports, the user's wrist in the functionally neutral posture. The carpal support extends beyond a distal end of the user's ulna bone when the user grasps the cursor control device. The functionally neutral posture has, at the distal end, the user's radial bone substantially vertically above their ulna bone.
Description
- This application claims priority to U.S. Provisional Application No. 61/614,852 filed on Mar. 23, 2012. This application is copending with U.S. Utility patent application Ser. No. 13/267,942 filed Oct. 7, 2011, the contents of which are fully incorporated herein by reference.
- The invention relates to electronic interface devices and methods of their manufacture, and more particularly, to customized, orthopedic cursor control devices and methods of easily fabricating them to closely conform to the relevant dimensions of an individual.
- The invention relates to for orthopedic electronic interface devices, such as an orthopedic computer mouse, is driven by the variety, and severity, of injuries such as, but not limited to, repetitive stress injuries, that are associated with the prolonged use of conventional computer mice and other conventional electronic interface devices. As many medical and scientific studies have confirmed, the repeated fine motor movements of the hand, wrist and forearm made in operating such conventional devices may result in painful, chronic conditions such as carpal tunnel syndrome, tendonitis, loss of grip strength, Raynaud's phenomenon, Dequervain's disease and trigger finger. These repetitive stress injuries are particularly prevalent when the cursor control device requires prolonged use with the hands or wrist in awkward or unnatural positions, or positions that require continuous activation of muscles, or with arthritis or in amputees.
- These repetitive stress injuries, and other related problems, may be avoided by having am electronic interface device designed to minimize stress on a user's hand and wrist. This may, for instance, be done by maintaining the user's hand in a functionally neutral posture during use of the device. An orthopedic cursor control device may also be designed to provide stability and to minimize the need for muscle activation when used to control the position of a cursor on a display screen. And in a further embodiment, the orthopedic cursor control device may also maintain a user's hand and wrist at a temperature within a therapeutically desirable range.
- The relevant prior art involving orthopedic cursor control devices includes:
- US Patent Application 20030098851 by S. Brink published on May 29, 2003 entitled “Pointing means for a computer” that describes a pointing means for a computer and to a method of achieving a position of rest for a person who operates a pointing means, said pointing means being ergonomically shaped to fill a human hand. The object of the invention is to avoid injuries by the use of the pointing means for a computer by ensuring that the joints, muscles and tendons of the hand and the arm are not strained unnecessarily in use. The pointing means may be constructed so that the thumb engages a recess (6) which is a lengthwise recess (6) with a thumb supporting face (20) having thumb support on a first side (22) and a second opposite side (24) where the recess (6) can have an extension supporting the thumb as well as engagement means (10) for the ball of the thumb. It is ensured hereby that the hand is in a position of rest while the pointing means is operated. The pointing means fills the hand, and the actual movement of the pointing means is performed by the forearm and the wrist. The muscles and tendons of the hand remain in the position of rest during operation of the pointing means. Mouse injuries can be prevented hereby.
- US Patent Publication 20010052894 by Segalle published on Dec. 20, 2001 entitled “Orthopedic computer mouse” that describes an orthopedic computer mouse which can be translated over a support surface, the mouse adapted for supporting the hand in the “physiological position” or “position of function”. The proposed shape was obtained from a mold of the human hand, and the mold was realized in the “position of function.” This position forces the user's hand to be placed in a position of function, thus eliminating the possibility of diseases. The present invention provides an orthopedic computer mouse which is “innocuous,” i.e., a computer mouse which has no adverse effect on, or which is harmless to the user. The mouse comprises a bottom surface, a forward end, a rear end, and opposite sides, and a generally hemispherical surface for supporting the fingers of a hand in a generally elevated orientation relative to the support surface with the little finger at a first elevation and the index finger located at a second elevation higher than the first elevation relative to the bottom surface. The generally hemispherical surface is further adapted for supporting the hollow of the hand so that the hand rests at an angle with respect to the forearm in the physiological position. The general hemispherical finger-supporting surface extends upwardly and laterally from one of the opposite sides. A thumb-supporting surface is provided for supporting the thumb of the hand, so that the mouse is securely gripped between the thumb and the fingers, the thumb supporting surface being disposed opposite the generally hemispherical finger-supporting surface.
- U.S. Pat. No. 6,545,665 by Rodgers published on Apr. 8, 2003 entitled “Adjustable computer pointing device” that describes a computer pointing device consists of a adjustable hand support shape and adjustable controls that work together to conform to an individuals natural grip. This allows multiple individual users to shape the device body for their maximum comfort using a squeezing action. A targeted ergonomic configuration allows a user to configure the angle of the hand in the most natural way to minimize twist and strain on the wrist. The adjustable structure and button assembly are attached to a flat bottomed base that rests on an underlying flat surface. Attached to the base are the electronic and the mechanical component necessary to provide the required positional and event outputs to a computer.
- U.S. Pat. No. 5,576,733 to Lo published on Nov. 19, 1996 entitled “Ergonomic computer mouse” that describes an ergonomic computer mouse includes an upright, primary finger-supporting surface for supporting all of the fingers of an upright hand in straight positions and in an upright stack. It also includes an opposite thumb-supporting surface for supporting the thumb. A hand holding the ergonomic computer mouse will be in a naturally upright and relaxed position, without requiring twisting of the hand, wrist, or forearm. As a result, fatigue, discomfort, and pain are minimized or eliminated even after a long period of continuous use.
- Various implements are known in the art, but fail to address all of the problems solved by the invention described herein. One embodiment of this invention is illustrated in the accompanying drawings and will be described in more detail herein below.
- The present invention is an orthopedic electronic interface device used, for instance, to control a position and function of a cursor on a display screen. The device is preferably a computer mouse, but may also be a game controller or a remote control. In other, preferred embodiments, the present invention may also be a foot-controlled user interface.
- In one preferred embodiment, the device may be hand operated and perform a control function while supporting a user's hand in a functionally neutral posture.
- The electronic interface device may, for instance, have a motion sensor housed in a base, a mound rigidly attached to the top of the base and a carpal support rigidly attached to the base. Portions of the surfaces of the base, the mound and the carpal support may function together to support a user's hand in a functionally neutral posture.
- In a preferred embodiment, the mound of the hand-held electronic interface device may be shaped to closely conform to an interior portion of the user's hand when the user's hand is in a grasping configuration. In addition, an inner surface of the carpal support may be shaped to closely conform to, and support, the user's wrist in the functionally neutral posture.
- The length of the carpal support may be such that it extends out beyond a distal end of the user's ulna bone when the user grasps the mound of the cursor control device with their hand.
- In a preferred embodiment, the functionally neutral posture of the wrist may be that position in which the distal end of the user's radial bone is substantially vertically above the distal end of the user's ulna bone.
- A further embodiment of the invention may include a wrist support rigidly attached to the base. The wrist support may extend out from the base to beyond the distal end of the user's ulna bone, and may have an upper surface shaped to support a part of a user's forearm.
- In a preferred embodiment, the outer surfaces of the mound of the hand-held cursor control device, the inner surface of the carpal support of the cursor control device and the upper surface of the wrist support of the cursor control device may form a contiguous surface. The contiguous surface, or device shell, may be shaped to closely conform to a particular user's hand. This is in marked contrast to existing, prior art devices that typically are designed to fit one prototypical sized user hand. Shaping the device to closely conform to a particular user's hand may, for instance, be achieved by a method such as, but not limited to, a molding process that uses a block of malleable material that has been grasped by the user's hand while the user's hand is in a functionally neutral posture. The mold, or the user's hand may be turned into suitable numerical data by, for instance, using a 3D optical scanner. The suitable numerical data may be feed raw or post-processed to a manufacturing device such as, but not limited to, to a computer controlled milling machine or lathe or 3D printing machine, or some combination thereof.
- Such a method may, for instance, include providing a block of malleable material in the approximate shape of the cursor control device to be produced. The person that the custom cursor control device is being prepared for, may, with their hand and wrist in the desired functionally neutral posture, grasp the block of malleable material. The user may then squeeze the malleable material so that the outer surface of the block assumes the shape of the inner surface of the user's grasping hand. The grasped block may then be prepared to function as a molding pattern, and the shell of the cursor control device molded from it, or a suitable 3D scan made of it for use in computer controlled manufacturing devices.
- Therefore, the present invention succeeds in conferring the following, and others not mentioned, desirable and useful benefits and objectives.
- It is an object of the present invention to provide a cursor control device that minimizes, or completely removes, the possibility of suffering a repetitive stress injury when using the device.
- It is another object of the present invention to provide a cursor control device that supports a user's wrist in functionally neutral posture.
- Yet another object of the present invention is to provide a cursor control device that is closely customized to an individual user.
- Yet another object of the present invention is to provide a cursor control device that may be heated or cooled to a therapeutically desired temperature.
- Still another object of the present invention is to provide a simple method of producing an orthopedic cursor control device.
- Still another object of the present invention is to provide an efficient, and cost effective, method of producing an orthopedic cursor control device that is customized for individual users.

Throughout this application,electronic interface device 100 will be shown as a right-handed device. One of ordinary skill in the art will readily appreciate that by mirroring any of the drawings about a vertical plane running from the front to the back of the device, or by applying such mirroring to any discussions of relative position of elements comprising the device, a left-handed device may be described that is functionally equivalent to the right-handed device. - In
FIG. 1 , the orthopedicelectronic interface device 100 is shown schematically to be supporting a user'shand 110 in a functionallyneutral posture 115. Thecursor control device 100 may be comprised of abase 120, amound 130 and acarpal support 140. - The functionally
neutral posture 115 of the user'shand 110 andwrist 190 is preferably a posture that may be maintained with little, or no, muscle activity. This may, for instance, be the position defined by adistal end 180 of the user'sradial bone 185 being located substantially vertically above adistal end 170 of the user'sulna bone 150. - The
mound 130 of thecursor control device 100 may, for instance, be shaped to closely conform to a relevant portion of the inner surface of the user'shand 110 when the user'shand 110 is grasping and positioned in the functionallyneutral posture 115. This close conformity to the inner surface of the user'shand 110 may be achieved by a method such as, but not limited to, molding a shell, or a portion of the shell of thecursor control device 100 from detailed measurements of the inner surface of the user's hand when the user'shand 110 is grasping and positioned in a functionallyneutral posture 115. The detailed measurements may be made by a method such as, but not limited to, making an impressing in molding clay, or by 3-D surface measurement device such as a 3-D laser profile sensor. - The
carpal support 140 of thecursor control device 100 may, for instance, extend beyond adistal end 170 of the user'sulna bone 150. -
FIG. 2 shows a rear view of a preferred embodiment of thecursor control device 100. In this view thecarpal support 140 may be seen as a curved, vertical ridge having aninner surface 160 that may closely conform to, and support, an inner and lower portion of the user'swrist 190. This close conformity of theinner surface 160 to inner and lower portions of the user'swrist 190 may be achieved by a method such as, but not limited to, molding a shell, or a portion of the shell of thecursor control device 100 from detailed measurements of the relevant inner and lower portions of the user's wrist when the user'shand 110 is grasping and positioned in the functionallyneutral posture 115. The detailed measurements may be made by a method such as, but not limited to, making an impressing in molding clay, or by 3-D surface measurement device. - The view of
FIG. 2 also shows themound 130 of thecursor control device 100 extending up above the user'sgrasping hand 110. -
FIG. 2 also shows thebase 120 of thecursor control device 100 and the attachedwrist support 210. Thewrist support 210 may be shaped to closely conform to, and support, the underside of the user'swrist 190, when the user is grasping thecursor control device 100 and is in the functionallyneutral posture 115. -
FIG. 3 shows a bottom view of the preferred embodiment of thecursor control device 100. Amotion sensor 320 may be housed in a hollow,concave cavity 350 in thebase 120. Thebottom surface 310 of thebase 120 of thecursor control device 100 may be substantially flat. - The
motion sensor 320 may, for instance, be a device capable of sensing relative motion between thebottom surface 310 of thebase 120 and any substantiallyhorizontal surface 240 on which thecursor control device 100 may reside. Themotion sensor 320 may, for instance, be a device such as, but not limited to, a computer mouse, a track ball, an optical computer mouse, one or more accelerometers or some combination thereof. -
FIG. 4 shows a side view of the preferred embodiment taken from the side with thecarpal support 140. Thecarpal support 140 may be a continuous, vertical ridge, extending up from thebase 120 of thecursor control device 100, when thebottom surface 310 of thecursor control device 100 rests on a substantiallyhorizontal surface 240. -
FIG. 5 shows a front view of the preferred embodiment of thecursor control device 100. This view showsactuators 510 that may have asurface 520 that protrudes through an opening 530 in the otherwise contiguous surface of themound 130. - The
actuator 510 may, for instance, be an electro-mechanical switch such as, but not limited to, a push button, a proximity switch, a pressure switch, a rotary switch or some combination thereof. -
FIG. 5 also shows adata link 330 that may connect to themotion sensor 320 via a datalink access channel 340. The data link 330 may be a wire link such as, but not limited to, an Ethernet cable, a USB cable, a fiber optic cable, or it may be a wireless data link such as, but not limited to, a blue tooth link, an Ethernet link or a WiFi link, or some combination thereof. The data link 330 may serve to transfer data regarding the position, relative position, motion or relative motion, or some combination thereof, of theelectronic interface device 100. This data may, for instance, be determined by themotion sensor 320. The data may be transferred to a remote device such as, but not limited to, a computer, a mobile device, a television set, or a data display device. The data link 330 may also serve to transfer information concerning the state of one ormore actuators 510. The transferred data may then be used to control a remote function such as, but not limited to, to the position of a cursor or other indicia 540 on a display screen 550. The transferred data may also, or instead, activate some function of the remote device such as, but not limited to, opening a browser window, or activating a software module linked to a current position of a cursor on a display screen. -
FIG. 6 shows a top view of the preferred embodiment. - The shell of the
electronic interface device 100 may be made of some suitably easy to mold material such as, but not limited to, thermosetting plastic, a thermoplastic, fiberglass, a polymer, a glass, a ceramic and a plastic. The surface of the shell or theelectronic interface device 100 may be draped, or covered, with a material that provides a required grip, comfort or other desirable property. - One suitable material for covering all, or part, of an orthopedic electronic interface device is the polymer AKTON® made by Action Products, Inc., of Hagerstown, Md. Akton is an ultra-soft elastomer, also called a dry visco-elastic polymer. The original formulation of Akton was designed to provide the softness of human fat tissue, but with resilience. The material is commercially available in a range of softness, and a range of thicknesses. Draping Akton that is between 1 and 2 mm thick, with a stress at 200% elongation of between 10-80 psi and more preferably between 15 and 50 psi, over all or part of the surface of the
cursor control device 100 may provide a suitable orthopedic device. - In a further embodiment, the
electronic interface device 100 may incorporate a heating or cooling capability. - Heating may, for instance, be provided by a conventional resistive element that may be thermostatically controlled to provide a predefined temperature to the surface, or a portion of the surface. The heating may be provided by several means including, but not limited to, a Peltier thermoelectric heat pump, a heatable gel-pad element that may, for instance, be incorporated in the
mound 130, thecarpal support 140 or thewrist support 210, or some combination thereof. - Cooling may be provided by several means including, but not limited to, a Peltier thermoelectric cooler, a coolable gel-pad element that may, for instance, be incorporated in the
mound 130, thecarpal support 140 or thewrist support 210, or some combination thereof. -
FIG. 7 shows a flow diagram of some of the steps of the method of manufacturing an orthopedic cursor control device of the present invention. - In
Step 810, a device blank, that may be a block of substantially malleable material, may be shaped to the approximate shape of the cursor control device. - The substantially malleable material of the device blank may be a material such as, but not limited to, clay, silicone, wax, low melting point plastic, putty, oil clay, polymer clay, paper clay, plastercine or some combination thereof.
- The
block 600 may, for instance, be shaped to approximate a base 120 that is sized to house amotion sensor 320 and having amound 130 that is rigidly attached to the top of thebase 120. Themound 130 may be approximately sized to fit an interior portion of agrasping hand 110 positioned in a substantially functionallyneutral posture 115. Theshaped block 600 or device blank, may also include an approximation of acarpal support 140 that may be rigidly attached to thebase 120. Theshaped block 600 may be approximately shaped such that the carpal support extends out beyond adistal end 170 of ausers ulna bone 150 when the user grasps the shapedblock 600. - In
Step 820, the device blank, or shapedblock 600 of substantially malleable material, may be grasped by the person for whom the custom orthopediccursor control device 100 is being manufactured. - The user may, for instance, grasp the shaped
block 600 approximation to amound 130 while their hand and wrist are in a functionallyneutral posture 115. The user may then gently squeeze the shapedblock 600 and allow their hand and forearm to rest on the substantially malleable material at the appropriate location. By squeezing the substantially malleable material and allowing their forearm and wrist to rest on it, the user will impart an imprint of the inside surface of their grasping hand and of the surface shape of their hand, wrist and forearm in the functionallyneutral posture 115. - In
Step 830 the grasped block ofmalleable material 700, or device blank, may be prepared to be a mold pattern for use in molding theelectronic interface device 100. This preparation will depend to some extent on the molding process and on the material theelectronic interface device 100 will be made of. - The molding process may be any standard process such as, but not limited to, compaction molding, compression molding, blow molding, thermoforming, vacuum forming and injection molding.
- The material used to make the molded
electronic interface device 100 thermosetting plastic, a thermoplastic, fiberglass, a polymer, a glass, a ceramic and a plastic. - Depending on the materials and molding method, the preparation of the grasped block of malleable material to transform it into a suitable mold pattern may include processes such as, but not limited to, removing a portion of the malleable material so as to ensure that a molded device can be easily removed from a mold formed from the molding pattern; adding or removing a layer or a partial layer of a the substantially malleable material so as to compensate for shrinkage or expansion of a the material that will form the molded cursor control device. The shrinkage or expansion may be calculated over a temperature change corresponding substantially to a change from a molding temperature of the molding material to approximately room temperature, which is often assumed to approximately in a range from 10 to 30 degrees centigrade, and often in the range of 20 to 25 degrees centigrade.
- In
Step 840, a mold may be formed from the mold pattern. This is a well known process and typically involves placing the mold pattern within a frame, and then filling the frame with molten or liquid mold material that will form the mold. When the mold material has cooled, hardened or otherwise set into a mold, the pattern is removed, leaving the mold as a “negative” copy of the mold pattern. Mold materials include, but are not limited to, silicone rubber, urethane rubber, urethane plastic, rigid & flexible foam, epoxy resins and polysulfide rubber. - In
Step 850, theelectronic interface device 100 may be made, or “molded”, using the mold formed using the mold pattern. This process is often called “casting” and typically involves filling the mold with molten or liquid material that will form the shell of thecursor control device 100, i.e., a material such as, but not limited to, thermosetting plastic, a thermoplastic, fiberglass, a polymer, a glass, a ceramic and a plastic, or some combination thereof. The casting may also involve the use of release agents to help ensure that the casting, or object made by the molding material, may be easily removed from the mold. - In
Step 860, theelectronic interface device 100 may be completed, or finished, by, for instance, adding appropriate electronics such as, but not limited to, themotion sensor 320, thedata link 330 and theactuators 510. The step of finishing may also involve machining the hollow,concave cavity 350 to house themotion sensor 320, and the datalink access channel 340, if these have not been produced in the molding process. -

FIG. 9 shows a front view of the block of malleable material being grasped. The grasped block ofmalleable material 700 may be seen to be being squeezed by the user'shand 110 to form amolding pattern 710 that may be a measurement of the inner surface of the grasper's clenched hand. In this view, a little finger of the grasper's hand may be seen forming thepinkie support 910. -
FIG. 10A shows a front perspective view of a block of malleable material after being grasped. The grasped block ofmalleable material 700 has now become amolding pattern 710 from which a mold may be cast. In this view, themound 130 and thepinkie support 910 are clearly visible. -
FIG. 10B shows a side perspective view of a block of malleable material after being grasped. The grasped block ofmalleable material 700 has now become amolding pattern 710 from which a mold may be cast. In this view, thewrist support 210, thecarpal support 140, themound 130 and thewrist 190 may all be clearly identified. - One of ordinary skill in the art will readily appreciate that this method of manufacture may readily be adapted to for some very specific medical uses such as, but not limited to, for producing devices suitable adapted to be suitable for people such as, but not limited to, arthritis sufferers, fibromyalgia sufferers, and people who are missing fingers or have malformed hands.
- One of ordinary skill in the art will readily appreciate that although much of the preceding discussion has been directed to computer related cursor control devices, the devices and method of manufacture may readily be applied to a wide variety electronic interface devices used in, for instance, video gaming, controlling program selection on a television including, but not limited to, gaming joysticks and trackballs. As with the individually customized computer mouse described above for illustrative purposes, the methods of manufacture described above may be used to produce a wide range of individually customized devices such as, but not limited to, individually customized joy sticks, track balls or game pads.
- For instance, may joy stick controllers have a hand held lever that is used to rotate what is essentially a track ball. The present invention may be adapted to such a device by, for instance, forming the handle to include one or more of a carpal support, a wrist support, a base for the hand and a pinky support. In that way, the even as the hand changes orientation as the joy stick of the joy stick controller is moved, the had will still be supported in a substantially neutral position through all, or most, of the motion necessary to control the electronic interface. This should reduce, or eliminate, repetitive motion fatigue and injury.

mould curser controller 1100 may consist of acurser control base 1110 into which a molded impression of individual user'shand 1120 has been imposed. This may be done by, for instance, an impression of the user's hand being obtained from a mold or by being scanned. This impression may then be digitized, subject to smoothing or correction algorithms, and then used to generate the hand-mould curser controller 1100. The generation may be by any suitable method such as, but not limited to, molding, computer controlled machining tool, 3D printing technology or some combination thereof. - The hand-

FIG. 16 shows a schematic isometric view from a first side of an orthopedic electronic interface device of a further embodiment of the present invention. - The view of
FIG. 16 shows anelectronic interface device 11 that has asupport structure 12 having asurface 13 shaped to support a user's hand (not shown inFIG. 16 ) in a substantially functionally neutral posture. Thesurface 13 shown inFIG. 16 has athumb imprint 14 that may, for instance, be custom fitted to a user's thumb. Theelectronic interface device 11 may have a wiredconnection 16 to the screen on which it is controlling a cursor, or it may be wirelessly connected, or some combination thereof. The motion sensor (not shown inFIG. 16 ) may, for instance, be an optical feedback mechanism located inside thesupport structure 12 near abase 17 of thesupport structure 12. -
FIG. 17 shows a schematic isometric view from a second side of an orthopedicelectronic interface device 11 of a further embodiment of the present invention. In the view ofFIG. 17 , thethumb imprint 14 in thesupport structure 12 is shown along with finger imprints 18. The finger imprints 18 may be custom molded to a user's hand using one or more of the techniques described above. Theelectronic interface device 11 also has apinkie cradle 19. Thepinkie cradle 19 may, for instance, be a concave shaped rest that may be rigidly attached to thesupport structure 12. Thepinkie cradle 19 may be sized and position so as to act as a rest for a portion of a user's small finger when the user's hand (not shown inFIG. 17 ) is positioned in a functionally neutral position on thesupport structure 12. Thepinkie cradle 19 may be custom shaped to fit a portion of a user's small finger using, for instance, one or more of the techniques described above. Thepinkie cradle 19 may, for instance, be shaped such that it may be used to move the electronic interface device laterally across a surface such as, but not limited to, a mouse pad. -
FIG. 18 shows a schematic isometric view of an orthopedicelectronic interface device 11 of a further embodiment of the present invention being used. - In
FIG. 18 , a user'shand 21 is shown holding thesupport structure 12. A user'sthumb 22 is shown locate in the thumb imprint 14 (shown inFIG. 17 ) and a user'sfingers 23 are shown located in the finger imprints 18 (shown inFIG. 17 ), such that the user'shand 21 may be held in a substantially functionally neutral posture. A user'ssmall finger 24, a.k.a. a pinkie finger, is shown resting in thepinkie cradle 19. -
FIG. 19 shows a schematic isometric view of corresponding, similar planes showing how motion may be transferred from one to the other using a further embodiment of the present invention. - A
first plane 6 may, for instance, be the plane in which anelectronic interface device 11 is moved such as, but not limited to, a mouse pad. The position of theelectronic interface device 11 may, for instance, be determined as a pair of coordinates indicative of a position as measured by, for instance, a distance from a common point of origin of two orthogonal coordinate axis, anx direction axis 31 anda y direction axis 32. Both thex direction axis 31 and they direction axis 32 may lie in a plane of thefirst plane 6. - The measured position of the
electronic interface device 11 may be translated into a similar position on asecond plane 5 that may, for instance, correspond to, or be closely mapped to, a display screen on which the electronically generatedindicia 2 may be displayed. This may, for instance, be accomplished using two orthogonal axis in the plane of thesecond plane 5 such as, but not limited to, anX axis 33 and aY axis 34. - The
electronic interface device 11 may include one or more user operated actuators 1 (not shown inFIG. 19 , but described in detail above). One of the user operated actuators 1 may, for instance, be able to be toggled between a first position 3 and a second position 7. - In the first position 3, the electronically generated
indicia 2 on the display device 4 (not shown inFIG. 19 ) may move substantially in a motion similar to the motion of theelectronic interface device 11. The motion of theelectronic interface device 11 in thefirst plane 6 may, for instance, be measured along thex direction axis 31 and they direction axis 32. Those measurements may then be translated into distances along theX axis 33 and theY axis 34 that may, for instance, have substantially the same ratio to each other as the distances measured in thex direction axis 31 and they direction axis 32. The electronically generatedindicia 2 may, therefore, move in thesecond plane 5 in a manner corresponding substantially to the movement of the motion-sensor of theelectronic interface device 11 in thefirst plane 6. - In the second position 7, however, the electronically generated
indicia 2 may be configured to be substantially independent of said movement of the motion-sensor in afirst plane 6. This functionality may, for instance, be used to allow a user of theelectronic interface device 11 to re-center, or otherwise reposition, theirelectronic interface device 11 within thefirst plane 6 that may, for instance, be their mouse-pad, without moving the electronically generatedindicia 2. This functionality may be useful when coming to, or near to, an edge of a mouse pad, but still wanting to move the electronically generatedindicia 2 further along the screen in the same direction. - In a further preferred embodiment of the invention, a user operated actuator 1 may be configured such that when the user operated actuator 1 is clicked the electronically generated
indicia 2 on the display device 4 moves to a predetermined position on the display device. - In yet a further preferred embodiment that predetermined place may, for instance, be substantially a
center 37 of the display screen. - In another preferred embodiment of the invention, a user operated actuators 1 may be configured such that on a first click the electronically generated
indicia 2 moves to a firstpredetermined position 36 on the display device, and on a second click the electronically generatedindicia 2 moves to a secondpredetermined position 38 on the display device. - Further clicks may, for instance, result in the electronically generated
indicia 2 moving to further predetermined positions on the display screen. These positions may recycle, i.e., after the nth position, the next click may bring the cursor back to the first position. N may be any reasonable integer number. - In a further, preferred embodiment, the user operated actuator 1 may be configured such that on a single click, the electronically generated
indicia 2 moves to a first position on the display screen, whereas if the user operated actuators 1 is double clicked, the electronically generatedindicia 2 moves to a second click. The number of clicks may, for instance, correspond to a particular predetermined position on the screen, such as, but not limited to, one click goes to the center, two click goes to the upper left hand corner, three clicks to the lower right hand corner. This sequence could be extended to any reasonable number of clicks and corresponding positions. The positions may also or instead be reached by a coded sequence, such as but not limited to, a code that is, or is similar, or derived from, the Morse code in which a time interval between click or a time in which the user operated actuators 1 is held down, or a combination thereof, may be used as part of the coding criteria. Such time may, for instance, be user adjustable. - Other preferred embodiment may include devices, features and methods such as, but not limited to, the following:
- The Nimble™ electronic interface device designed for Mild to Moderate Conditions. It is a marriage of form and function, suitable for those seeking to avoid or to significantly reduce pain of the hand and arm from use of the computer mouse. The custom-molded product offers an alternative to the standard computer mouse and other mass-produced ergomonic products.
- The Ortho™ is designed for Moderate to Extreme Physical and Neurological Conditions. It may be fully customized. The orientation of the hand, position and purpose of the buttons, may, for instance, all be defined and customized for a user's particular situation by a user and/or their clinician.
- With a FreeSlide™ feature, the optics of the Ortho™ may be temporarily disabled with a simple tap of a finger, as described above in more detail with respect to
FIG. 19 . This may allow the user to reset the position of the mouse without having to lift the device. It may also enables those suffering with hand tremors to halt the movement of the cursor to make a selection. One of ordinary skill in the art will readily appreciate that a feature such as the FreeSlide™ need not be limited to a custom electronic interface device but may be applied to any suitable curser control device. - The manufacturing process may include steps such as, but is not limited to:
- Step 1: Mold
- A hand molding kit may contain substantially everything needed to make a custom mold of a user's hand in the correct, ergonomic position. An instructional video may be included in the kit.
- The kit may include several high quality, impression foam molding blocks such as, but not limited to, a fine-celled thermoset phenolic plastic foam similar to that used in forensic work and supplied by Bio-foam Impression Molding Systems.
- Step 2: Scan
- The mold may enter a scanning process in which a state-of-the-art, high speed laser scanning technology may be used to render a virtual 3D image of the molded hand. This information may be used for the next step of the process.
- Step 3: Customize
- Once scanned into a database, the molded hand information may be sent to a Customization Laboratory that may include a 3D mechanical design software tool.
- The
