Sensing device for coded electronic ink surface
First Claim
Patent Images
1. A sensing device for use with a surface having coded data and electronic ink disposed on he surface, the coded data being indicative of an identity of a region associated with the surface, the sensing device including:
- an image sensor adapted to optically sense at least some of the coded data when placed in an operative position relative to the surface;
a region identity generator configured to generate region identity data indicative of the identity of the region using at least some of the optically sensed coded data; and
a transmitter configured to transmit the region identity data to a computer system.
