Sensing device having an image sensor and a movement sensor
First Claim
1. A sensing device comprising:
- an image sensor configured for sensing and capturing images of at least some coded data on a surface when the sensing device is placed in an operative position relative to the surface, the coded data being indicative of at least a unique identity of the surface, and locations on the surface;
a processor for processing the captured images to determine the unique identity of the surface and the operative position of the sensing device on the surface;
a movement sensor, comprising a pair of orthogonal accelerometers, for generating movement data; and
a transmitter for transmitting indicating data to the computer system, the indicating data comprising data regarding the identity of the surface, data regarding the operative position of the sensing device and said movement data.

Abstract
A sensing device for sensing coded data on a surface, generating indicating data, and transmitting the indicating data to a computer system is provided. The coded data is indicative of at least a region identity of the surface, whilst the indicating data comprises data regarding a region identity of the surface and data regarding movement of the sensing device relative to the surface. The sensing device comprises: (a) an image sensor configured for sensing and capturing images of at least some of the coded data when the sensing device is placed in an operative position relative to the surface; (b) a processor for generating the region identity component of the indicating data using the captured images; (c) a movement sensor for generating the movement component of the indicating data; and (d) a transmittor for transmitting the indicating data, comprising the region identity data and the movement data, to the computer system. The processor is configured to: (i) identify at least some of the coded data from one or more of the captured images; (ii) determine an orientation, within the captured images, of the at least some of the coded data; (iii) decode the at least some of the coded data; and (iv) generate data regarding the region identity of the surface using the decoded coded data.
