Abstract
A method of identifying edge touch gesture has steps of scanning the touch device under a hover mode; scanning the touch device under a touch mode; determining if there is a touch object on the touch device according to a scanning result of the touch mode; and when there is a touch object on the touch device, identifying the gesture according to a scanning result of the hover mode and the scanning result of the touch mode. Accordingly, the method can perform valid touch on the edge area, rendering effective identification of edge touch gesture and an increased success rate of the identification.
Claims21
A method of identifying touch gesture for determining an object executing a gesture on a touch device, the method comprising steps of:
- a. scanning the touch device under a hover mode;
- b. scanning the touch device under a touch mode;
- c. determining if there is a touch object on the touch device according to a scanning result of the touch mode;
- and
- d. when there is a touch object on the touch device, identifying the gesture according to a scanning result of the hover mode and the scanning result of the touch mode.
A touch system comprising:
- a touch device;
- a controller electrically connecting to the touch device, wherein the controller executes following steps:
- a. scanning the touch device under a hover mode;
- b. scanning the touch device under a touch mode;
- c. determining if there is a touch object on the touch device according to a scanning result of the touch mode;
- and
- d. when there is a touch object on the touch device, identifying the gesture according to a scanning result of the hover mode and the scanning result of the touch mode.
