Summary of the invention
The present invention discloses a kind of touch detection method, particularly in the touch point determination methods that a kind of dynamic adjustment judging area is provided, it is by a mode of dynamically adjusting judging area, judges in advance whether this touch point moves and moving direction export its displacement information.
According to a category of the present invention, a kind of touch point determination methods, it moves the position of front and back according to the set positions one touch-control judging area of a touch-control object according to this touch-control object, dynamically adjust this touch-control judging area, so that reaction time and preferably controllability to be faster provided.
According to one embodiment of the invention, touch point determination methods is applied to a contact panel, this contact panel sequentially outwards has one first observation area from one center, one first promoter region and a turnover zone, touch point determination methods comprises: a primary importance of setting a touch point is a center of this first observation area, whether a second place that judges this touch point is positioned at this first promoter region, when this second place is during in this first promoter region, set this touch point and be a mobile status and take this second place as a center, sequentially outwards set one second observation area and one second promoter region.When this second place is positioned at this first observation area, setting this touch point is a stationary state.When this second place is positioned at this turnover zone, setting this touch point is a mobile status.
According to another embodiment of the present invention, can equate also can be unequal for the area of this second observation area and the area of this first observation area.Wherein, the reaction time that touch point moves is corresponding to the size of the area of the first observation area and the second observation area, and the length in this reaction time is corresponding to reaction sensitivity, and this reaction time and this reaction sensitivity are inversely proportional to.
Therefore, compare traditional touch point judgment mode, the present invention can define at least one determination range by setting this dynamic judging area, and dynamically adjust the determination range of this dynamic judging area by this touch point determination methods, to shorten the reaction time in the dynamic judgement of touch point, and improve reaction sensitivity and accuracy.

Embodiment
Please refer to shown in Fig. 1 and Fig. 2, the preset state schematic diagram of the dynamic judging area of Fig. 1 the present invention, Fig. 2 is the process flow diagram of an embodiment of touch point determination methods of the present invention.Determination methods is applied to a contact panel, and this contact panel sequentially outwards has one first observation area 10, one first promoter region 12 and a turnover zone 14 from one center.
In the present embodiment, touch point determination methods comprises: the primary importance that S20 sets a touch point 16 is that a center, the S21 of this first observation area 10 judges whether a second place of this touch point 16 is positioned at this first promoter region 12, S22 when this second place is during in this first promoter region 12, set this touch point 16 and be a mobile status and S23 take this second place as a center, sequentially outwards set one second observation area and one second promoter region.
This determination methods separately comprises that step S24 works as this second place and is positioned at this first observation area 10, and setting this touch point 16 is a stationary state.
As shown in Figures 1 and 2, this first observation area 10 is the circle of a radii fixus, this first promoter region 12 is the annular sections centered by this first observation area 10, and the outer perimeter of the area of this first observation area 10 and this first promoter region 12 maintains a fixed proportion, this turnover zone 14 is the outer peripheral areas beyond this first promoter region 12.
Further, as described in step S22, in the time that the second place of this touch point 16 is positioned at this first promoter region 12, represent that touch-control object (for example: finger or pointer) may want to move, now, setting this touch point 16 is a mobile status, to enter the preparation in advance of turnover zone 14 as this touch point 16, shorten the reaction time in the dynamic judgement of touch point, improve reaction sensitivity.
More person, please coordinate with reference to shown in figure 3A and Fig. 3 B, as described in step S23, in the time that touch point 16 is positioned at the first promoter region 12 (Fig. 3 A) and is judged as mobile status, contact panel can separately define one second observation area 30 and second promoter region 32(Fig. 3 B), and the center of the second observation area 30 is the second place of this touch point 16.In addition, as described in step S24, in the time that the second place of this touch point 16 is positioned at this first observation area 10, though represent that this touch-control object has a displacement, but in fact this touch-control object will not move, now, setting this touch point 16 is a stationary state, causes the situation of erroneous judgement to avoid too responsive detecting.
For instance, this touch-control object may be subject to the impact of external noise or vibrations (for example, the vehicles in advancing) and cause there is micro-displacement, though this micro-displacement represent this touch-control object and have locational variation, but still can be considered stationary state.
This determination methods more comprises that step S25 works as this second place and is positioned at this turnover zone 14, and setting this touch point 16 is a mobile status.
In an embodiment, the area of this second observation area 30 equates with the area of this first observation area 10, but, also can be unequal in the area of another embodiment the second observation area 30 and the area of this first observation area 10.Wherein, the reaction time that touch point 16 moves is the size with the area of this second observation area 30 corresponding to this first observation area 10, and the length in this reaction time is corresponding to reaction sensitivity, and this reaction time and this reaction sensitivity are inversely proportional to.In simple terms, if the area of this first observation area 10 is larger, the displacement of this touch point 16 will be got over great talent certainly has way to move to this first promoter region 12, relatively, if it is too little that the area of this first observation area 10 is set, a little rocking all likely causes this touch point 16 to shift out this first observation area 10.
Therefore, compare traditional touch point judgment mode, the present invention can define at least one determination range by setting this dynamic judging area, and dynamically adjust the determination range of this dynamic judging area by this touch point determination methods, to shorten the reaction time in the dynamic judgement of touch point, and improve reaction sensitivity and accuracy.
Only as described above, be only preferred embodiment of the present invention, when can not be in order to limit the enforceable scope of the present invention, all know this case field have common skill personage variation and the modification that obviously can do, all should be considered as not departing from flesh and blood of the present invention.
