Abstract
A force sensitive surface measures force or pressure applied to the surface. The surface may also detect the touch position. The force sensing surface is calibrated with a stylus having a force measuring element. The stylus measures the force information from force applied on the surface and sends the information to the device with the force sensing surface. The device detects the same force and calibrates the force sensing element according to the information received from the stylus. The device may also detect the position of the touch. As the force information obtained from different portions of the surface may be different, the calibration may be repeated for multiple positions on the force and touch sensitive surface. The calibration may also be used to calibrate a position sensing feature on a force sensing surface having multiple force sensors.
