General Touchscreen Properties:

Optional properties for Touchscreens:

  • touchscreen-size-x : horizontal resolution of touchscreen
               (in pixels)
    
  • touchscreen-size-y : vertical resolution of touchscreen
               (in pixels)
    
  • touchscreen-max-pressure : maximum reported pressure (arbitrary range
               dependent on the controller)
    
  • touchscreen-fuzz-x : horizontal noise value of the absolute input
               device (in pixels)
    
  • touchscreen-fuzz-y : vertical noise value of the absolute input
               device (in pixels)
    
  • touchscreen-fuzz-pressure : pressure noise value of the absolute input
               device (arbitrary range dependent on the
               controller)
    
  • touchscreen-average-samples : Number of data samples which are averaged
               for each read (valid values dependent on the
               controller)
    
  • touchscreen-inverted-x : X axis is inverted (boolean)
  • touchscreen-inverted-y : Y axis is inverted (boolean)
  • touchscreen-swapped-x-y : X and Y axis are swapped (boolean)
               Swapping is done after inverting the axis
    
  • touchscreen-x-mm : horizontal length in mm of the touchscreen
  • touchscreen-y-mm : vertical length in mm of the touchscreen

               touchscreen-fuzz-x and touchscreen-fuzz-y
