Experience Level: Expert
We provide windows tablets to a variety of customers, some of which require Windows XP. However, unlike Windows 7, you cannot calibrate the touchscreen in WinXP the same way you can in Win7. We believe the problem is that Win7 is happy to see the touchscreen as just that, where as WinXP seems to expect that you are using a digitizer pen for the touch. Thus when using the built in calibrate function of WinXP, although the screen displays the first cross hair, tapping it does nothing. Touch is working under XP, but the calibration is off, and this is was we need to fix, either by letting XP know that tapping the screen should be equal to a touch with a pen, or by writing a new calibration program that writes calibration data into the registry wherever that may be. Maybe even a driver needs to be written, we're not sure. But like I said touch does work in XP, it's pretty much the same as clicking a mouse, and the calibration sucks.
