First Claim
Patent Images
1. An optical pen, comprising:
- an elongated housing having a distal end;
an optical sensor located within the housing and configured to receive input light from a viewing surface through a distal opening at the distal end of the housing;
a tip extending from the distal end of the housing and being positioned adjacent to the distal opening, the tip being positioned to not obstruct the input light to the optical pen when the most distal portion of the tip is in contact with the viewing surface.
