在触摸板上获取手指位置

Question

Is there any way to get the location that touch pad is touched? also I need capture module that is able to return such 2D points array map that reports states of touchpad points (state means: is point touched/not touched ) by request. No matter on what technology/language it is written

Answer 1

I know this isn't what you want to hear, but there is no all-inclusive way to do what you want.

Individual makes and models have their own way of exposing it. For example, I've done some work with Synaptic touchpads (fairly common) which expose a COM interface on Windows. That code won't work on any other touchpads.

You could find a few common ones and run different code based on which ones the system supports.

Answer 2

如果它是一个Windows应用程序，处理WM_MOUSEMOVE消息，则lparam的hiword和loword分别是x和y坐标，参考客户区域坐标。
