Problems solved by technology

However, this method cannot effectively suppress the noise that is likely to cause false pressing, especially in order to cope with the calculation of the two limiting conditions (contact time and moving range), and the construction cost of the logic circuit is relatively high.

Embodiment Construction

[0019] refer to image 3 , the controller 100 of the touch device 300 of the present invention is used to identify an action of an object 200 on the touch device 300 , and send a control signal corresponding to the action to a host 400 . It should be noted that the touch device 300 can generally refer to capacitive, inductive and other similar touch devices 300 , and in this example, it refers to a capacitive touch device 300 in particular.

[0020] The object 200 is used to contact the touch device 300, that is, according to the action of the object 200 on the touch device 300, the controller 100 will send a corresponding control signal representing its action to the host 400. Generally, these control signals It can be divided into coordinate change, click, double-click, drag, move, scroll, left button, right button, middle button, etc., to further simulate the behavior of the mouse and keyboard. Certainly, the object 200 needs to cooperate with the touch device 300 , such a...

Abstract

This invention provides a method for identifying one stroke operation, which tests the happening of an operation and begins timing when a subject contacts with a touch-control device, then tests the finish of the operation of the contact so as to get the first time distance of the contact and timing is finished after second time distance is timed. If the second time distance is greater than the first, the first one is greater than a preset one, if operation is generated with the contact only one contact time greater than the preset time distance in said second time distance, the control signal expressing the one stroke operation will be generated.

Description

technical field [0001] The invention relates to a single-click action recognition method of a touch device, in particular to a recognition method capable of effectively suppressing noise and improving recognition rate, and a controller using the method. Background technique [0002] The touch pad is a humanized input device, because the keyboard, mouse, trackball and other input devices in the past failed to fully meet the needs of users, and because today's electronic products are designed with light, thin, short , small orientation, since it is impossible to integrate all types of input devices, and the touchpad can not only meet the requirements of multi-level menu design, but also have humanized operation methods such as keyboard, mouse and handwriting input, so has become the most popular choice. [0003] refer to figure 1 After the touch panel 10 generates an analog voltage signal, it performs analog / digital conversion through a controller 20 and calculates the coord...
