Abstract
A computer system has a touch sensitive display screen within a housing and a touch sensor, which is coupled to a bus. A processor and a memory are coupled to the bus. The housing has a channel for receiving and storing a stylus. A sensor is disposed adjacent to the channel. The sensor interacts with the stylus through the Hall effect caused by a magnet within the stylus and is thus operable for detecting a presence or absence of the stylus without physical contact therewith. The memory has an application which, when executed on the processor, automatically performs one or more stylus related software functions upon a reported absence of the stylus from the channel. One of the software functions includes palm detection rejection with respect to data from the touch sensor. Another function includes display of a GUI displaying a listing of applications that are based on stylus data entry modes. Another function includes setting up OS modes designed for accurate operation of stylus data entry.
