Abstract: This invention provides apparatus and a method which self-adjust the pressure response of a digitizer pointing device or other device incorporating a pressure transducer according to the characteristics of the particular device and/or particular user of the device. For example, a digitizer user when inputting with a stylus pointing device may use different writing styles in simulated paint brush and in simulated chalk, or, the user may use the stylus device entirely differently when using it in a game or in a graphic arts application, or different users may use the same stylus device differently for the same application. Certain pressure parameters of the device are not set on a fixed basis, which would provide for an average, typical or generic pressure range and resolution.
