Abstract

A device including a housing, a writing tip connected to the housing, a writing surface position indicator, a processor in the housing, a memory device in the housing connected to the processor, and a sensor in the housing and cooperative with the writing surface position indicator. The device may be used to record writings and drawings applied to a surface by a user, to transmit that data to a remote device, to download data from remote devices, and to otherwise communicate with remote devices.

Claims

1. A device for recognizing writing on a writing surface, comprising:

a housing;

a writing tip connected to the housing;

a writing surface position indicator removeably attachable to a writing surface;

a processor in the housing;

a memory device in the housing connected to the processor; and

a sensor in the housing and cooperative with the writing surface position indicator.

2. The device of claim 1, further comprising a plurality of accelerometers connected to the writing tip.

3. The device of claim 2, further comprising a pressure sensor connected to the writing tip.

4. The device of claim 1, wherein the writing surface position indicator includes a signal transmitter.

5. The device of claim 4, wherein the sensor includes a signal receiver.

6. The device of claim 5, wherein the sensor includes a second signal receiver.

7. The device of claim 5, wherein the writing surface position indicator includes a second signal transmitter.

8. The device of claim 4, wherein the writing surface position indicator includes a signal transmitter selected from the group consisting of a active signal transmitter and a passive signal transmitter.

9. The device of claim 4, wherein the writing surface position indicator includes a signal transmitter selected from the group consisting of an infrared signal transmitter, an ultrasonic signal transmitter, and an electromagnetic signal transmitter.

10. The device of claim 1, wherein the memory device includes instructions stored thereon which when executed by the processor cause the processor to determine a relative position between the writing tip and the writing surface.

11. The device of claim 10, wherein:

the sensor periodically receives a signal from the writing surface position indicator; and

the memory device includes instructions which when executed by the processor cause the processor to periodically update the relative position between the writing tip and the writing surface.

12. The device of claim 1, wherein the memory device includes instructions which when executed by the processor cause the processor to recognize data written with the writing tip on a writing surface.

13. The device of claim 12, wherein the memory device includes instructions which when executed by the processor cause the processor to execute commands in response to the recognized data.

14. The device of claim 12, wherein the memory device includes instructions which when executed by the processor cause the processor to recognize a user-defined interface defined by the recognized data.

15. The device of claim 1, further comprising a base connected to the housing.

16. A device for recognizing writing on a writing surface, comprising:

a writing instrument including a writing tip, a plurality of accelerometers for detecting motion of the writing tip, a pressure sensor connected to the writing tip, at least one signal receiver, a memory device and a processor, wherein the processor is in communication with the accelerometers, the pressure sensor, the signal receiver and the memory device; and

a writing surface position indicator removeably attachable to the writing surface, the writing surface position indicator including at least one signal transmitter for transmitting a signal to be received by the signal receiver of the writing instrument,

wherein the memory device includes instructions stored thereon, which when executed by the processor, cause the processor to recognize markings made by the writing tip on the writing surface based on inputs from the accelerometers, the pressure sensor and the signal receiver.

17. The device of claim 16, wherein the writing surface position indicator is removeably attachable to the writing instrument.

18. The device of claim 16, wherein the writing instrument includes a second signal receiver for receiving the signal transmitted by the writing surface position indicator, and wherein the processor is in communication with the second signal receiver.

19. The device of claim 16, wherein the writing surface position indicator includes a second signal transmitter for transmitting a second signal to be received by the signal receiver of writing instrument.

20. The device of claim 16, wherein the memory further includes instructions, which, when executed by the processor, cause the processor to recognize a user-defined interface drawn by a user with the writing instrument on the writing surface.
