Abstract

Provided is a scanning device for scanning a surface having coded data disposed thereon which is substantially invisible to the average unaided human eye. The device is configured to determine at least two dimensions of a rotational orientation of the sensing device relative to the surface, the coded data being indicative of at least two dimensions of the rotational orientation of the sensing device. The device includes an orientation sensor configured to generate, when positioned or moved relative to the surface, using at least some of the coded data, orientation data indicative of the at least two dimensions of the orientation of the sensing device relative to the surface, a transmitter for transmitting the orientation data to a computer system, and a pressure sensor to facilitate activation of the orientation sensor when a nib of the pen-shaped device is pressed against said surface.

Claims

1. A scanning device for scanning a surface having coded data disposed thereon which is substantially invisible to the average unaided human eye, the coded data being indicative of at least two dimensions of the rotational orientation of the sensing device, said device comprising:

a housing;

an electronics chassis mounted in the housing;

an orientation sensor arranged on the chassis and configured to generate, when positioned or moved relative to the surface, using at least some of the coded data, orientation data indicative of the at least two dimensions of the orientation of the sensing device relative to the surface;

a transmitter arranged on the chassis for transmitting the orientation data to a computer system; and

a pressure sensor to facilitate activation of the orientation sensor when a nib of the pen-shaped device is pressed against said surface.

2. The pen-shaped scanning device of claim 1, further including a region identity sensor configured to sense, when the sensing device is positioned or moved relative to a region of the surface, and using at least some of the coded data, region identity data indicative of an identity of the region, the transmitter being configured to transmit the region identity data to the computer system.

3. The pen-shaped scanning device of claim 1, wherein the coded data includes periodic elements, the periodic elements being substantially identical marks within the coded data which assist the sensing device in locating the coded data, the device further including a motion sensor configured to generate the movement data on the basis of the sensing device'"'"'s movement relative to at least one of the periodic elements.

4. The pen-shaped scanning device of claim 3, wherein the motion sensor is configured to sample the position of the sensing device relative to the at least one reference point or periodic element, thereby to generate the movement data.

5. The pen-shaped scanning device of claim 4, further including a distance estimator configured to estimate a distance of the sensing device from the at least one reference point or periodic element.

6. The pen-shaped scanning device of claim 5, wherein the transmitter is configured to transmit distance data to the computer system, the distance data being indicative of the distance.

7. The pen-shaped scanning device of claim 6, wherein the motion sensing means is configured to use the distance estimated by the distance estimator to resolve a more accurate position of the sensing device than indicated by the at least one reference point or periodic element alone.
