Abstract

The invention discloses a method and a device for identifying a rotation gesture. The method for identifying the rotation gesture comprises the following steps of: generating a plurality of coordinate pairs by a plurality of continuous coordinates which are obtained by a coordinate input interface, wherein each coordinate pair comprises a start coordinate and an end coordinate; judging the orientation of each coordinate pair from the start coordinate to the end coordinate; and judging the rotation gesture according to the orientation of the coordinate pairs. The device for identifying the rotation gesture comprises a memory, the coordinate input interface and a programmable processing unit, wherein the memory memorizes a rotation gesture judgement program and a plurality of reference orientation ranges which are determined according to clockwise direction or anticlockwise direction; the coordinate input interface comprises a touch device and a controller; and the programmable processing unit identifies the rotation gesture according to the rotation gesture judgement program.

Description

technical field [0001] The present invention relates to a device and method for recognizing touch gestures, in particular to a device and method for recognizing rotation touch gestures. Background technique [0002] The rotation gesture (rotation gesture) is often applied in the field of touch control, and is mainly triggered by an arc-shaped touch track, and the controller or processor recognizes the arc-shaped touch track to correspond to a specific command or trigger the program. [0003] The most common rotation gesture is applied on a specific touch-sensing track, that is, the touch-sensing track defines a predetermined recognizable area of ​​the rotation gesture, and the rotation gesture can be recognized along the touch-sensing track. Such as Figure 12 As shown in the sensing disc (such as Jog Dial) in the circular area, when the finger moves along the circular area on the sensing disc, the controller can judge a rotation gesture through the position information on ...
