Abstract:
1. An electronic pen for interacting with a substrate having coded data disposed thereon, the pen comprising: an image sensor for sensing at least some of the coded data when the pen is used to interact with the surface; a cartridge having a nib for contacting said surface; a retraction mechanism for slidably moving said cartridge between a refracted position wherein said nib is retracted within a body of said pen and an extended position wherein said nib protrudes from said body; a force sensor cooperating with said retraction mechanism, said force sensor being configured to sense a force applied to said surface by said nib when said nib is in said extended position; and a processor configured to generate, using at least some of the sensed coded data, indicating data indicative of the interaction with the substrate; wherein said image sensor is configured to sense said coded data only when said force sensor detects that said nib is in contact with said substrate.
