  # Basic Parameters
  touch.deviceType = touchScreen

  # Touch Size
  touch.touchSize.calibration = pressure
  
  # Tool Size
  # Driver reports tool size as an area measurement.
  #
  # Based on empirical measurements, we estimate the size of the tool
  # using size = sqrt(22 * rawToolArea + 0) * 6 + 0.

  # Pressure
  # Driver reports signal strength as pressure.
  #
  # A normal index finger touch typically registers about 80 signal strength
  # units although we don't expect these values to be accurate.
