Get finger position on touch pad

Question

Is there a way to touch the touchpad? I also need a capture module that can return such a map of an array of 2D points that reports on the states of the touchpad points (state means: point affected / not affected ) upon request. No matter what technology / language is written

Answer 1

I know that this is not what you want to hear, but there is no comprehensive way to do what you want.

Individual models and models have their own way of exposing. For example, I did some work with Synaptic touchpads (fairly common) that invoke the COM interface on Windows. This code will not work on other touch panels.

You can find some common ones and run other code, on the basis of which the systems are supported.

Answer 2

If his Windows application processes the WM_MOUSEMOVE message, hiword and loword lparam are the x and y coordinates, respectively, in relation to the coordinates of the client area.
