what is touch sensitivity ?

      what is touch sensitivity ?

      New

      1. A resistive touch panel is perfect, when used with a tip pen, but quite uncomfortable when a finger shall be used to hit buttons etc.According to the device driver manual, one can specifiy a "DeltaX/YCoordTolerance" key. I set these keys to 50 (default is 20 - NetDCU8), but there is no significant effect.Perhaps, hardware should be modified, in order to obtain a better sensitivity.Any ideas? (thanks)
