Problems solved by technology

However, the difficulty of design has also increased a lot. In terms of wiring, generally a projected capacitive mobile phone panel needs to be connected with at least 15 lines. Difficulty is also higher
In addition, since the sensing unit matrix is ​​arranged in the same layer space, it will squeeze the touchable area of ​​the sensing unit matrix, and reducing the area will lead to a decrease in sensitivity, and adjacent traces are also likely to cause capacitance leakage problems, especially temperature, Humidity can easily affect the accuracy of sensing

Abstract

The invention relates to an optical multi-touch method of a window interface for controlling objects in a window interface. The optical multi-touch method comprises the following steps: providing a first optical sensing window to obtain a first track signal, and providing a second optical sensing window to obtain a second track signal; analyzing the first track signal to decide a first displacement direction, and analyzing the second track signal to decide a second displacement direction; and controlling the action of the objects in the window interface according to the relative relation of the first displacement direction and the second displacement direction.

Description

technical field [0001] The invention relates to a control method for a windowed interface, in particular to an optical multi-point touch method for a windowed interface. Background technique [0002] A computer input device generally refers to a hardware device (Hardware Device) that can input a coordinate displacement signal to a computer device (such as a personal computer, a notebook computer, or a personal digital assistant, etc.). There are many types of visible computer input devices, such as a mouse, a trackball, etc. Devices, trackpads, pen tablets, joysticks, etc. are included. Wherein, except that the mouse can input the coordinate displacement signal to the computer device according to the movement of the user, the mouse is also provided with a scroll wheel, which can also control the vertical scroll bar or the horizontal scroll bar of the windowed interface, and is further provided below the scroll wheel. There is a micro switch, and the user can issue a confirm...
