First Claim
Patent Images
1. An optical stylus for use with a host device, the optical stylus comprising:
- a image capture device configured to obtain images of encoded, location indicative patterns;
a processor coupled to the image capture device;
one or more orientation determining components coupled to the processor;
a pressure sensor coupled to the processor and configured to sense pressure applied to an end of the stylus; and
an antenna coupled to the processor, wherein the antenna is configured to transmit data collected by the optical stylus to the host device.

Abstract
An optical stylus and host computing system is provided, as are methods related to the operation thereof. In particular, in an example embodiment, a method of operating the optical stylus is provided that includes determining when the optical stylus is in contact with a surface based on signals received by a processor from a pressure sensor of the optical stylus and capturing an image while the optical stylus is in contact with the surface using a camera of the optical stylus. The captured image is then transmitted to a host system.
