The invention provides a multi-point gesture identification method and a multi-point translation gesture identification device. The method comprises the following steps of: (A) detecting an induction waveform which is caused by touch of an object along at least one direction of the touch device; (B), determining the number of objects touching the touch device according to the detected induction waveform; (C), judging whether the number of objects is greater than a preset number; (D), if the number of objects is greater than the preset number, recording touch states and moving traces of the objects touching the touch device; and (E), judging whether the objects move in the same direction according to the touch states and the moving traces of the objects; and (F), if the objects move in the same direction, determining that a multi-point gesture is a translation gesture. By the embodiment of the invention, the multi-point gesture can be simply and quickly identified; a cursor or an image can move or words and images can be paged by identifying whether the objects move in the same direction; and a user can use the multi-point translation gesture identification device conveniently.
Description
technical field [0001] The invention relates to the technical field of electronic equipment manufacturing, in particular to a multi-point gesture recognition method and a multi-point translation gesture recognition device for a touch device. Background technique [0002] With the rapid development of technology, earth-shaking changes have taken place in electronic products. With the advent of touch electronic products recently, more and more touch products have been welcomed by people. Touch products not only save space and are easy to carry, but also users can directly operate with fingers or stylus, which is comfortable and convenient to use. For example, personal digital processing (PDA), touch mobile phones, portable notebook computers, etc., which are common in the market today, have all increased investment in touch technology, so touch devices will be more widely used in various fields in the future. Applications. [0003] At present, capacitive touch panels have be...
