filter driver for touch screen RRS feed

  • Question

  • Hello,

    I'd like to write a filter driver for a (very large) touch screen in order to be able to discriminate between finger touch and stylus touch based on the area of contact with the device, thus enabling an external app to have different behavior for each case.

    I'm a neophyte writing drivers, so I'd like to know:

    1. if I can use UMDF2 model rather than KMDF
    2. If I should get it done by writing a hid driver filter
    3. Is there a good tutorial to start with

    Many Thanks!
