Abstract: A writing instrument that also functions as a computer peripheral. The writing instrument has the general configuration of a ball-point pen. The pen includes a ball for ink writing that is operatively associated with internal sensors that precisely detect the distance and direction of ball movement and relay that directional and distance data to a microprocessor which records a series of vectors similar to a computer mouse. The pen also includes interchangeable memory cartridge for the storage of the data and a wireless computer connect, for example infrared, that can communicate generated or stored data to an associated computer. The pen also includes an external LED data display, a speaker/microphone and an ink reservoir.
