I was hoping it may appears as a mouse device, so its just a case of configuring it then dropping buttons where i want touch inputs.

The main criterion is: > Are you expecting taps to come from a delicate stylus or a chunky > finger? Chunky finger all the way on this app. Probably 17" LCD touchscreen so thinks like a number pad will be most of a screen. I'll probably run in full screen mode all the time and the app will be set to auto start at power on. The system is a 800Mhz micro atx. so there is no issue getting any software to run that i want, no complicated cross compiles or anything like that. I want to loose the keyboard an mouse, the last thing you want in a production environment is a keyboard hanging of the equipment when it is just not necessary and a well designed (haha thats my job) interface will make the equipment much easier to use. I want the minimum number of thinks to see or touch. Thanks Robin
