Description

Touch Point Judgment Method

technical field

The present invention relates to a touch detection method, in particular to provide a touch point judgment method for dynamically adjusting the judgment area.

Background technique

With the rapid progress of human science and technology, the user interface of many electronic products has changed from the traditional button type to the touch type under the impetus of technological development. The emergence of the touch type user interface enables people to operate electronic products conveniently and freely. Electronic products with a control-type user interface have become necessary in modern people's lives.

In terms of the current touch detection technology, the judgment method uses a static area and a moving area as the basis for judging the movement of the touch point. When the position of the touch point is in the static area, even if the touch point moves slightly , the touch point is considered to be in a static state and does not output direction or movement information; when the touch point leaves the static area and enters the moving area, it is considered that the touch point is in a moving state, and then the direction or movement information begins to be output. However, the setting of the size of the static area will affect the reaction time of the touch point movement judgment. If the range of the static area is too large, it will inevitably make the reaction time longer. If the range of the static area is set too small, it may cause any noise. Or vibration will be identified as the moving state, in other words, if only a static area and a moving area are used as the basis for judgment, not only will the judgment of the movement path near the center of the touch judgment area fail to obtain correct results, but it will also affect the touch control. Judgmental reaction time and controllability.

Therefore, is there a method or mechanism that can make the judgment of the touch point avoid the shortcomings caused by the improper setting of the quiet zone range, thereby improving the response time and better controllability of the touch point judgment.

Contents of the invention

The present invention discloses a touch detection method, in particular to provide a touch point judgment method for dynamically adjusting the judgment area, which judges in advance whether the touch point moves and the direction of movement by dynamically adjusting the judgment area. Output its displacement information.

According to one aspect of the present invention, a method for judging a touch point, which sets a touch judgment area according to the position of a touch object, and dynamically adjusts the touch judgment area according to the position of the touch object before and after movement, so as to Provides faster response time and better controllability.

According to an embodiment of the present invention, the method for judging a touch point is applied to a touch panel, and the touch panel has a first observation area, a first activation area, and a movement area sequentially outward from a central position thereof, The touch point judging method includes: setting a first position of a touch point as a central position of the first observation area, judging whether a second position of the touch point is located in the first activation area, when the second When the two positions are in the first activation area, the touch point is set to a moving state and the second position is taken as a center position, and a second observation area and a second activation area are set outward in sequence. When the second position is located in the first viewing area, the touch point is set to be in a static state. When the second position is located in the moving area, the touch point is set as a moving state.

According to another embodiment of the present invention, the area of the second viewing area may or may not be equal to the area of the first viewing area. Wherein, the reaction time of the touch point movement corresponds to the size of the first observation area and the second observation area, and the length of the reaction time corresponds to the reaction sensitivity, and the reaction time is inversely proportional to the reaction sensitivity.

Therefore, compared with the traditional touch point judgment method, the present invention can define at least one judgment range by setting the dynamic judgment area, and dynamically adjust the judgment range of the dynamic judgment area through the touch point judgment method to shorten the touch The reaction time on point dynamic judgment can be improved, and the reaction sensitivity and accuracy can be improved.

Detailed ways

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a schematic diagram of a preset state of a dynamic judgment area of the present invention, and FIG. 2 is a flow chart of an embodiment of a touch point judgment method of the present invention. The determination method is applied to a touch panel, and the touch panel has a first observation area 10 , a first activation area 12 and a moving area 14 from a central position to the outside in sequence.

In this embodiment, the method for judging a touch point includes: S20 setting a first position of a touch point 16 as a center position of the first observation area 10; S21 judging whether a second position of the touch point 16 is Located in the first activation area 12, S22, when the second position is in the first activation area 12, then set the touch point 16 as a moving state and S23 take the second position as a center position, and move to A second viewing area and a second activation area are set outside.

The judging method further includes step S24 , when the second position is located in the first viewing area 10 , setting the touch point 16 to a static state.

As shown in Figures 1 and 2, the first observation area 10 is a circle with a fixed radius, the first activation area 12 is an annular area centered on the first observation area 10, and the first observation area 10 The area of the moving area 14 is a peripheral area outside the first activation area 12 while maintaining a fixed ratio to the outer perimeter of the first activation area 12 .

Further, as described in step S22, when the second position of the touch point 16 is located in the first activation area 12, it means that the touch object (such as a finger or a stylus) may intend to move. At this time, Setting the touch point 16 to a moving state serves as a pre-preparation for the touch point 16 to enter the moving area 14 to shorten the reaction time of the touch point dynamic judgment and improve the response sensitivity.

What’s more, please refer to FIG. 3A and FIG. 3B. As described in step S23, when the touch point 16 is located in the first activation area 12 (FIG. 3A) and is judged to be in a moving state, the touch panel will define another The second observation area 30 and the second activation area 32 ( FIG. 3B ), and the center position of the second observation area 30 is the second position of the touch point 16 . In addition, as described in step S24, when the second position of the touch point 16 is located in the first observation area 10, it means that although the touch object has a displacement, the touch object does not actually move. At this time, the touch point 16 is set to be in a static state, so as to avoid misjudgment caused by oversensitive detection.

For example, the touch object may be affected by external noise or vibration (such as a moving vehicle), resulting in a slight displacement. Although the slight displacement indicates that the touch object has a position change, it can still be regarded as Stationary state.

The judging method further includes step S25 , when the second position is located in the moving area 14 , setting the touch point 16 to a moving state.

In one embodiment, the area of the second observation area 30 is equal to the area of the first observation area 10, however, in another embodiment, the area of the second observation area 30 and the area of the first observation area 10 may also be different. equal. Wherein, the reaction time of the touch point 16 moving corresponds to the size of the area of the first observation area 10 and the second observation area 30, and the length of the reaction time corresponds to the reaction sensitivity, and the reaction time is proportional to the reaction sensitivity. inverse ratio. To put it simply, if the area of the first observation area 10 is larger, the displacement of the touch point 16 must be greater to move to the first activation area 12. On the contrary, if the area of the first observation area 10 If the area is set too small, a little shaking may cause the touch point 16 to move out of the first viewing area 10 .

Therefore, compared with the traditional touch point judgment method, the present invention can define at least one judgment range by setting the dynamic judgment area, and dynamically adjust the judgment range of the dynamic judgment area through the touch point judgment method to shorten the touch The reaction time on point dynamic judgment can be improved, and the reaction sensitivity and accuracy can be improved.

But the above-mentioned ones are only preferred embodiments of the present invention, and should not be used to limit the scope of the present invention. All changes and modifications that are obvious to those with ordinary skills in the field of this case should be regarded as unreasonable. Deviate from the essence of the present invention.
