Data input device, systems using the device, and methods for operating such systems

摘要

A data storage device 5 having a storage capacity of at least 8 Mbyte is surrounded by a housing including a stylus portion 23 , having a tip 25 for indicating a position. The stylus permits the data storage device 5 to be used for data entry to a electronic device 19 such as a PDA which traces the position of the stylus tip. The data storage device 5 can be used in place of a conventional stylus. Thus, the user of the electronic device 19 which traces the position of a stylus is able to enjoy the advantages of a data storage device without being obliged to use an additional component.
