Stylus & Touch Tester visualizes touch screen & stylus input by displaying touch point along with its associated pressure, tilt & orientation information on the screen. The input value is also recorded and measured to calculate the sensitivity & resolution of the input device so you can see clearly its capability.
For pressure sensitive stylus, it measures X, Y axis movements, and resolution of its pressure sensitivity (minimum delta between different inputs, and the number of levels it can detect). If the stylus supports tilt & orientation detection, these values are being measured as well.
For touch input, the touch size is being measured along with X, Y axis movements, the resolution is also calculated.
