Hello Hackers, I'm playing with the psm driver and a symantics touchpad - I'd like to send the touch pressure along with x/y coordinates/buttons and then chenge the behaviour of mouse in moused using the pressure. What would be better: 1. Extend the struct mousestatus with additional pressure field. 2. Use the mousestatus's z axis movement (dz field). It in fact IS the third dimension, right? The whole concept of z being used for scrolling at times, and at times scrolling being just additional buttons is odd to me. 3. Use another ioctl like MOUSE_SYN_GETHWINFO to fetch the pressure value. What would be best? m.
