Touch Device And Touch Trajectory Sensing Method Thereof

Abstract

The present invention relates to a touch device and a touch trajectory sensing method thereof. The touch device includes a sensing panel and a control unit. The touch trajectory sensing method is used for moving trajectory determination of a touch object on the sensing panel. When a plurality of touch objects are operated with special moves, such as steered or stayed, on the sensing panel to generate a plurality of touch points with different moving trajectories, the control unit determines a trajectory sensing area of each touch point according to a movement speed of the touch point. In addition, since the trajectory sensing area exhibits a positive correlation with the movement speed, multiple touch points adjacent to the touch objects at the turning positions or the retarded positions will have smaller trajectory sensing area due to reduction of speed. Thus, the present invention can prevent the touch points with different moving trajectories from falling into the opponent trajectory sensing areas, prevent the control unit from making a wrong moving trajectory determination, and further prevent the sensing panel from performing an unexpected touch control operation.

Description

technical field [0001] The present invention provides a touch device and a touch track detection method thereof, in particular, when a plurality of touch objects perform special actions such as turning, sliding or staying on a sensing panel, the touch points are judged according to the moving speed of the touch points. The track detection area of ​​the contact point is to prevent the control unit from making a wrong judgment on the moving track when the contacts of different moving tracks fall into the mutual track detection area. Background technique [0002] Press, today’s electronic products are in line with human’s intuition, touch devices have been widely used in various electronic products, so that users can use touch objects such as fingers or stylus to touch or Swipe to perform touch operations on electronics. [0003] see Figure 13 , Figure 14 , Figure 15 As shown, it is one, two, and three of the action schematic diagrams of the known technology. It can be cl...

[0004] When two touch objects slide adjacent to each other on the sensing panel to form a moving track K 1 、K 2 , the control unit will sequentially detect the first contact M 11 , M 21 , the second contact M 12 , M 22 and the third contact M 13 , M 23 , however, since the two touch objects are respectively controlled by the second contact M 12 , M 22 Steering slip to third contact M 13 , M 23 , the third contact M 23 located adjacent to the second contact M 12 and falls on the second contact M 12 The second track detection area A 12 , which in turn causes the control unit to simultaneously switch the second contact M 12 with the third contact M 13 , M 23 It is judged as the same movement trajectory, so that the control unit performs an unexpected touch operation on the sensing panel
