Problems solved by technology
This method can only detect single point and cannot realize multi-point detection
In addition, the traditional method cannot detect the action content of the touch object on the touch panel, for example, the touch object performs a rotation or zoom action on the touch panel, etc.

The invention proposes a recognition method for multi-point rotary motion. The identification method includes the following steps: A: detecting the induction waveform caused by the touch of an object on the touch device along at least one direction; B: determining the object touching the touch device according to the detected induction waveform number; C: if it is determined that the number of detected objects is multiple, then determine whether the plurality of objects perform rotational motion; and D: if the multiple objects perform rotational motion, the touch device generates a control signal , and perform a control operation on the touch device according to the control signal. The invention also provides a recognition device for multi-point rotary motion of the touch device. The method and device for recognizing multi-point rotating motions according to the embodiments of the present invention can accurately recognize multiple objects and the rotating motions generated by the objects touching.
Description
technical field [0001] The present invention relates to object recognition, in particular to a method and device for recognizing multi-point rotational motions of object numbers, the multi-point rotational motion recognition method and device can be used to recognize the number and / or rotational motion of multiple objects respectively . Background technique [0002] With the rapid development of technology, earth-shaking changes have taken place in electronic products. With the advent of touch-sensitive electronic products recently, touch-control products have become more and more popular. 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 assistants (PDAs), 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 widel...
