ELECTRONIC PEN WITH RETRACTABLE NIB

摘要

An electronic pen for interacting with a substrate having coded data disposed thereon. The pen comprises: an image sensor for sensing the coded data when the pen is used to interact with the surface; a slidably retractable nib for contacting the surface; and a processor configured to generate indicating data indicative of the interaction with the substrate. The image sensor is configured to sense the coded data only when the nib is configured in the extended position.
