PEN-TYPE COMPUTER

Abstract

A pen-type computer includes a pen barrel, a sensor, a primary processor, and a storage device. The pen barrel has a writing tip. The sensor is disposed in the pen barrel, sensing movement of the writing tip and generating a tracking signal corresponding to the movement of the writing tip. The primary processor is disposed in the pen barrel, encoding the tracking signal into data and storing the data in the storage device.
