Touch control device and gesture determining method

Abstract

The present invention relates to a touch control device and a gesture determining method. According to the determining method, a first area is defined from one side of the touch control device in a direction departing from the side; the first area is separated from the side for a certain distance; a plurality of pieces of position information are read in certain time; after a fact that the position of a first object falls into a first area is determined, displacement difference between a first piece of position information and a random piece of position information is calculated; and when the displacement difference exceeds a preset value, an edge slip sweeping gesture is determined. Because a distance is kept between the first area and the side of the touch control device, a majority of fingers in slip sweeping gesture fall into the first area, and displacement amount of the finger of which the initial speed is not zero is preset in cooperation with non-zero speed of the finger with edge slip sweeping gesture into the first area. Therefore the correct edge slip sweeping gesture can be accurately determined.

Description

technical field [0001] The invention relates to a touch device, in particular to a control device capable of correctly judging touch gestures. Background technique [0002] In order to facilitate users to replace the mouse function, the touch device or external touch device of a notebook computer basically has a cursor control function, a left button function and a right button function. Added "edge swipe gesture control function". For example, when the computer system enables the window function bar hiding function, when the user uses the touch device to perform cursor control functions, left-click functions, and right-click functions, the window function bar is hidden. Once the touch device determines that the current When the user's control gesture is "edge swipe", the computer system will automatically display the function of the hidden function bar on the window screen for the user to click; in addition, the page switching function is also applicable.

[0009] However, the above judgment methods still have a certain rate of misjudgment in actual use, one of which is caused by assembly defects in the mechanism; please refer to Image 6 As shown, when the touch device 10 is assembled to the notebook computer casing 20, its top surface cannot be flush with the top surface of the notebook computer casing 20 and there is a height difference, causing the user's finger to touch and slide from the casing 20 to the touch device 10. Outdated, the first location information cannot meet the condition of falling into the first area, and this gesture will not be correctly judged as an edge swipe gesture

Another reason for the misjudgment of the edge swipe gesture is: the width of the first area is generally set so as not to interfere with the normal cursor control, so its width will not be too wide, so when the finger slides directly from the notebook computer casing 20 into the touch device quickly At 1
