Description

The present application claims priority to provisional application 60/798,033 filed May 4, 2006, titled “Gloves with integral sensors and electronics to simulate riding a motorcycle,” claims priority to provisional application 60/812,213, filed Jun. 9, 2006, titled “Gloves with integral sensor and electronics to simulate riding a motorcycle,” and claims priority to provisional application 60/846,210, filed Sep. 20, 2006, titled “Gloves with integral sensors and electronics to simulate riding a motorcycle.” The contents of these provisional applications are incorporated herein by reference.

BACKGROUND

Various products attempt to give users a realistic and exciting simulated motorcycle driving experience. For example, one such product includes full-motion game controllers that may be used with video games. These devices enable a user to apply realistic driving motion to control operation of the video game.
Full-motion game controllers may include motorcycle handlebars that enable a user to utilize wrist flexure to control the throttle of a simulated motorcycle in a video game. In turn, the video game responds with video and sound corresponding to the user's actions.
Such prior art toy products may suffer from several problems. In particular, the play action can be restricted to operation of the video game. While the full action operation may include some user activity, the user remains predominantly sedentary apart from hand/wrist movement. Further, some users may wish to utilize their imagination and experience to simulate motorcycle driving outside of the video game environment.

SUMMARY

An interactive wrist cover for simulating riding a vehicle is provided. The interactive wrist cover includes various components that respond to a user's realistic driving motions by generating appropriate outputs, such as increasing engine speed sound in response to wrist flexure to simulate throttle operation, even when no handle bar is present. The components thereby enable a simulated vehicle operation in virtually any location, including within and outside the video game environment. For example, a user may utilize the wrist cover while riding a non-motorized vehicle, such as a bike, to make it feel as if the vehicle is in fact powered by an engine.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows an example pair of wrist covers worn by a user;
FIGS. 2A, 2B, and 2C show cross-sectional views of a wrist cover in a plurality of positions; and
FIGS. 3A and 3B show a high level flowchart of example operations performed by a wrist cover.

WRITTEN DESCRIPTION

FIG. 1 shows a pair of wrist covers 110, including right wrist cover 120 and left wrist cover 122, being worn by a user on each of a right hand 112 and a left hand 114. While the wrist covers are shown with various functional and decorative shapes and designs, modifications can be made to these elements without departing from the scope of this disclosure. For example, the wrist covers can be designed to simulate motocross racing styles, touring styles, etc. Furthermore, while FIG. 1 shows a pair of wrist covers, only a single wrist cover may be provided.
Right wrist cover 120 is shown having a right finger covering section 132, a right hand covering section 134, and a right forearm covering section 136. Section 132 is rotatably coupled to section 134 via rotary pin joint 140. Similarly, section 134 is rotatably coupled to section 136 via rotary pin joint 142. The pin joints may form a hinge, such that the different wrist sections are hinged relative to one another. While in this example a rotation joint having a single degree of freedom between the wrist covering sections is provided, various other flexible couplings may be used. For example, the rotatable couplings may include a flexible joint that rotates via bending a resilient coupling member, or may include a flexible fabric or leather coupling piece. Sections 132, 134, and 136 may be formed from various materials, such as plastic, rubber, etc.
The wrist cover 120 may be removeably coupled to the user's right hand 112 via plastic strap elements 160, 162, and 164. As shown in FIG. 1, strap 160 may be coupled to one side of right hand covering section 134 and positioned in front of the user's thumb so that it wraps around the user's palm (not shown). Further, strap 162 may be positioned on the same side of right hand covering section 134 but behind the user's thumb. Sections 160 and 162 may further include Velcro, making it possible for them to connect to strap 164, which is coupled to the other side of right hand covering section 134. Such a strap system enables the wrist cover to fit a variety of hand sizes, thereby facilitating easy attachment and detachment from the user. While this example illustrates three strap elements, various other approaches may be used to removably couple the wrist cover to the user, such as elastic bands, straps with a buckle, strings, snaps, buttons, etc.
Right hand covering section 134 is shown having an exterior housing 150 that may include an integral speaker cover 152, which, in turn may include a plurality of perforations or holes covering a speaker. As described in further detail herein, right hand covering section 134 may also include various sensors, batteries, electronics, and controllers, such as a speaker for generating sounds, lights for generating illumination, IR emitters and/or receivers, a control circuit and/or various other output generators. In one example, a control circuit may generate output, such as sounds, in response to various sensor inputs. Also, although not shown in FIG. 1, right hand covering section 134 may further include visual read-outs (such as a tachometer, speedometer, etc.), as well as input devices, such as buttons, knobs, dials, etc.
Right hand covering section 134 may also include a mode selection switch (not shown), having two, three or more switch options/positions for enabling a user to select an operation mode. As described in further detail with regard to FIG. 3, different operations may be performed in response to various sensor inputs depending on the mode selection. For example, the first mode may be a deactivated (or off) mode, the second mode may be a single increasing engine speed (or “rev”) mode, and the third mode may be an acceleration and cruising mode.
Right hand covering section 134 may be shaped and/or formed to fit around the back side of the user's right hand 112. Specifically, a bottom surface of section 134 may be concave to more closely fit the user. Likewise, sections 132 and 136 may also have bottom surfaces shaped to form fit the user, or may be formed of substantially planar shapes.
Joint 142 may include an integral cam element (see FIG. 2), which enables detection of the degree of relative rotation between right hand covering section 134 and right forearm covering section 136 via a sensor coupled in right hand covering section 134. While in this example a cam and deflection sensor are used, various other sensor configurations may be used to indicate flexure between sections 134 and 136. For example, a strain gauge mounted on a bending joint member may be used to measure angular deflection between sections 134 and 136. As another example, a rotary potentiometer may be used to measure the rotation of a joint 142. Still, other approaches may be used if desired.
In one example, a circuit in right hand covering section 134 may generate engine sounds, where the amplitude and/or frequency of the engine sounds are correlated to the degree of wrist flexure by the user, as measured via joint 142. The degree of wrist flexure may thus simulate increasing throttle actuation, which in turn produces increasing engine speed and/or power sounds. Such operation may enhance the experience of riding a bike or other activity in which the user may pretend to ride a motorcycle. In other words, as the right hand simulates the movements required to rev a throttle grip of a motorcycle, motorcycle engine sounds are emitted from a speaker embedded on the wrist cover. These sounds may correspond to the amount of simulated rotation of the imaginary throttle, with more rotation resulting in a faster and/or more powerful sounding engine. Alternatively, a contact switch may be coupled to joint 142, such that upon actuation of a cam element, a revving engine speed sound is produced upon contact, irrespective of the degree of rotation past the point of initial switch contact.
FIG. 1 further shows wrist cover 122 coupled to left hand 114, with similar left finger, hand, and wrist covering sections 172, 174, and 176, respectively, and joints 180 and 182. Left wrist cover 122 may be symmetric, or asymmetric, with respect to wrist cover 120.
For example, left wrist cover 122 may have similar wrist flexure sensing and output generation as right wrist cover 120, wherein engine or honking horn sounds are produced, or it may include additional and/or alternative features. In the example of FIG. 1, a sensor may measure finger deflection of user's left hand 114 via the degree of rotation between left hand covering section 174 and left finger covering section 172, and, in turn, communicate this information to a circuit in left hand covering section 174. Further, left hand covering section 174 may generate shifting sounds in response to the finger flexure to further enhance the simulation of motorcycle riding. In other words, as the left hand is moved to simulate pulling a motorcycle clutch lever, shifting sounds may be generated.
In still another example, right wrist cover 120 may also include a sensor to measure finger flexure via joint 140, and further generate braking sounds in response to the sensed finger flexure.
By providing multiple aspects of motorcycle riding between the pair of wrist covers, it is possible to enable increased riding simulation and enable skill development, as well-coordinated movements of the right and left hands may result in smooth shifting and acceleration sounds.
In some examples, communication may be provided between two wrist covers. For example, wired or wireless communication from wrist cover 120 to and from wrist cover 122 may be provided, such as via infrared (IR) communication, visible light communication, ultrasonic or audible sound communication, or radio frequency (RF) communication. For example, the wrist covers may communicate the amount of deflection of various joints. Such operations may enable one or both wrist covers to generate output, such as sound, in response to the coordinated operation of the left and right wrist cover.
In this way, it may be possible to for a user to develop further skill as the wrist covers 110 generate outputs, such as sounds, responsive to well-coordinated movements of the right and left wrist covers together, while also generating output such as mechanical noises and engine sounds associated with poorly executed shifting in a real motorcycle in response to poor coordinated movements of the left and right wrist covers.
As noted above, a simulated, electric or electronic visual indicator or indicators may be provided, such as on right or left hand covering section 164/174. These indicators may include a simulated tachometer or speedometer. In one example, a simulated tachometer may provide a readout of the simulated engine speed sounds, with corresponding changes reflecting the position of the right “throttle” wrist flexure and the fingers of the left “clutch” finger flexure.
While FIG. 1 shows example wrist covers that do not completely cover the arm, hand, or fingers, various alternative configurations may be used. For example, form fitting gloves may be used with corresponding sensors (e.g., position bump switches) placed on the palm and/or back of the wrist sections of the gloves. Thus, as the user's hand moves in selected ways, the switches are closed, or other types of sensors are actuated, causing associated sounds, visual effects, or other actions to occur as described herein. Further, while the above described embodiment is directed to motorcycle riding, various other vehicular configurations may be used, such as for a snowmobile, jet-ski, construction equipment, etc. Further, various sounds and or sensor effects may be used in addition to engine and braking sounds, such as horn sounds, crashing sounds, vibration, etc.
FIG. 2 shows a side cross-sectional view of an example wrist cover 120 with like components labeled as in FIG. 1, where the wrist cover is shown in three different positions. Further FIG. 2 shows spring loaded cam element 220 rotating about joint 142, as well as internal compartment 210, which may house electronics, batteries, etc. As the spring loaded cam is rotated counterclockwise against a stop (not shown), and thus in the example where cam 220 is coupled to an internal position detection sensor (not shown), the sensor indicates a non-flexed position.
Specifically, FIG. 2A shows the wrist cover in a position before a user has initiated wrist flexure, and before surface 222 of forearm section 136 has contacted cam element 220.
FIG. 2B shows the wrist cover in a position after the user has rotated from the position of FIG. 2A, where surface 222 has just contacted, but not moved, cam 220. Again, in the position of FIG. 2B, the spring loaded cam 220 is rotated counterclockwise against the stop, and the sensor indicates a non-flexed position.
FIG. 2C shows the wrist cover in a position after the user has further rotated from the position of FIG. 2B and generated sufficient wrist flexure to actuate cam 220 to the point of activating the internal position sensor. As such, the sensor indicates that wrist flexure is detected.
Referring now to FIG. 3, a routine is described that may be performed by circuits or a processor embedded in a wrist cover, such as embedded within wrist cover 120. The following process may be performed by code stored within computer readable storage media, or may performed by electronic circuits, etc. In the example depicted in FIG. 3, various operating modes may be selected by a user that produce varying wrist cover performances in response to user inputs. Specifically, three distinct operating modes may be selected, including:

- mode 1: which represents an inactive state,
- mode 2: which represents a single engine rev mode, where upon actuation of a user's movement (e.g., wrist flexure), a single increasing engine speed (or rev) is generated; and
- mode 3: which represents an accelerating and/or decelerating engine speed, along with shifts, and then a sustained cruising engine speed and transmission sound and/or idling sound.

In this example, various sound recordings of various durations are selectively played back through a speaker in a wrist cover, where the various recordings represent one or more components of the sounds produced during the above modes, and differing playback operations are, in turn, provided in these different modes. The operation according to FIG. 3 thus enables numerous play patterns using a single-position wrist flexure sensor and a three-position mode selector switch.
In 310, the routine reads a mode selection switch, and determines a user-selected mode, such as mode 1, 2, or 3. When mode 1 is selected, the routine continues to 312 and no sound or other output is emitted, where mode 1 may be referred to as “off.” When mode 2 is selected, the routine continues to 314, and when mode 3 is selected, the routine continues to 316.
Mode 2 provides a single engine increasing engine speed sound, or “rev,” in response to detection of user input, such as wrist flexure. When wrist flexure is not detected, no sound is produced, unless a “rev” is in progress, in which case the “rev” plays to completion, and then no sound is produced. In this example, the single increasing engine speed sound recording is referred to a recording 1. While a single recording is repeatedly used in this example, the routine may alternatively utilize a plurality of different recordings, which are randomly selected for playback, or played in a specified order.
Mode 3 provides a more complex play pattern, in which a continuous idling sound (recording 2) is played when no wrist flexure is detected. Upon detection of wrist flexure, an accelerating engine and transmission recording (recording 4) is played, where the engine repeatedly increases in speed as if repeatedly shifting to higher gears. Then, assuming wrist flexure is still detected, upon reaching the last, or highest gear, a cruising sound recording (recording 5) is continuously played. Further, upon detection that wrist flexure is removed or stopped, a deceleration engine and transmission recording (recording 3) is played. Then, assuming wrist flexure is still not detected, upon completion of the deceleration, the idling recording (recording 1) is again repeatedly played.
Returning to the details of FIG. 3A, in 314, the routine determines a user body position, such as a wrist position as measured at joint 142. In this example, a single position sensor is used that indicates either wrist flexure is detected (position 2), or is not detected (position 1); however, a continuously variable angle or position sensor may also be used as noted herein. If position 1 is detected (e.g., no wrist flexure), the routine continues to 320 to determine whether playback of recording 1 is in process. If so, the routine continues to 322 to continue playback of recording 1; otherwise, the routine continues to 324 and no output or sound is produced. In other words, if recording 1 has begun playing due to wrist flexure, but the wrist flexure is stopped, playback of recording 1 continues until completion of the recording.
Likewise, if position 2 is detected (e.g., wrist flexure), the routine continues to 326 to determine whether playback of recording 1 is in process. If so, the routine continues to 322 to continue playback of recording 1; otherwise, the routine continues to 328 to initiate playback of recording 1. In other words, upon detection of wrist flexure, playback of recording 1 is initiated, unless it is already being played. Further, after the completion of playback of recording 1, no sound is produced even if wrist flexure is continued. Thus, a single increasing engine speed sound is generated.
When mode 3 is selected, the routine determines wrist flexure position in 316. When position 1 is detected, the routine continues to 330 to determine whether the previous position of the user's wrist was position 2 upon the last execution of the routine. If so, the routine continues to 332 in FIG. 3B to initiate playback of recording 3. Otherwise, the routine continues to 334 to determine whether playback of recording 3 is completed, or still in progress. If it is in progress, the routine continues to 336 to continue the playback of recording 3. If not, the routine continues to 338 to playback recording 2, or continue/repeat playback of recording 2.
In mode 3 when position 2 is detected, the routine continues to 340 in FIG. 3A to determine whether the previous position of the user's wrist was position 1 upon the last execution of the routine. If so, the routine continues to 342 in FIG. 3B to initiate playback of recording 4. Otherwise, the routine continues to 344 to determine whether playback of recording 4 is in progress. If not, the routine continues to 346 to initiate playback of recording 5. If so, the routine continues to 348 to continue playback of recording 4.
In this way, even though a 2-position wrist sensor is used, a wide variety of play patterns and simulated motorcycle riding operation may be provided. While FIG. 3 represents an example operation of the right wrist cover 120, similar operations may also be provided by left wrist cover 122. Alternatively, the left wrist cover may utilize a 2-mode switch, where during a first mode the wrist cover is deactivated (or “off”) and during a second mode a horn sound is generated upon detecting wrist flexure.
While the present invention has been described in terms of specific embodiments, it should be appreciated that the spirit and scope of the invention is not limited to those embodiments. For example, the disclosed wrist covers may communicate with a video game console and be used to control operation of a vehicle, such as a motorcycle, in the video game.
