Orientation sensing device for use with coded marks
First Claim
1. A sensing device for generating at least two-dimensional orientation data when positioned or moved relative to a surface, the orientation data being indicative of at least two dimensions of an orientation of the sensing device relative to the surface, the surface having coded data disposed upon it, the coded data comprising a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions and being indicative, when sensed by the sensing device, of the orientation, the sensing device including:
- a housing;
an orientation sensor configured to generate the orientation data using at least some of the coded data the orientation data being indicative of at least two of the pitch, yaw and roll of the sensing device relative to the surface; and
a communicator configured to communicate the orientation data to a computer system.

28. A sensing device for generating orientation data when positioned or moved relative to a surface, the orientation data being indicative of an orientation of the sensing device relative to the surface, the surface having coded data disposed upon it, the coded data being indicative, when sensed by the sensing device, of the orientation, the sensing device including:
-
a housing;
an orientation sensor configured to generate the orientation data using at least some of the coded data, the orientation data being indicative of at least two of the pitch, yaw and roll of the sensing device relative to the surface;
a motion sensor for generating at least position data indicative of the position of the sensing device relative to the surface;
a communicator configured to communicate the orientation data to a computer system; and
a memory adapted to store a sensing device identifier which is adapted to distinguish the sensing device from other sensing devices of the same type.
