the sensor periodically receives a signal from the writing surface position indicator; and
the memory device further 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.
-
-
15. The device of claim 1, wherein the memory device further includes instructions which when executed by the processor cause the processor to recognize data written with the writing tip on the writing surface.
-
16. The device of claim 15, wherein the memory device further includes instructions which when executed by the processor cause the processor to execute commands in response to the recognized data.
-
17. The device of claim 15, wherein the memory device further includes instructions which when executed by the processor cause the processor to recognize a user-defined interface defined by the recognized data.
-
18. The device of claim 1, further comprising a base connected to the housing.
-
19. A method for defining an interface, comprising:
-
monitoring movement of a writing instrument on a writing surface;
recognizing a command area on the writing surface defined by movement of the writing instrument;
associating a command with the command area; and
determining whether the writing instrument touches the writing surface within the command area. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
periodically producing a signal from a fixed location relative to the writing surface;
receiving the signal at the writing instrument; and
updating a position of the writing instrument relative to the fixed location.
-
-
22. The method of claim 19, further comprising periodically producing a signal from a fixed location relative to the writing surface.
-
23. The method of claim 22, wherein producing a signal is selected from the group consisting of producing an infrared signal, producing an ultrasonic signal, and producing an electromagnetic signal.
-
24. The method of claim 22, wherein producing a signal is selected from the group consisting of producing an active signal and producing a passive signal.
-
25. The method of claim 22, wherein determining the relative position includes determining the relative position by triangulation.
-
26. The method of claim 22, further comprising producing a second signal from a second fixed location relative to the surface, wherein the fixed location and the second fixed location are spaced apart by a distance.
-
27. The method of claim 19, further comprising determining movement of the writing instrument on the writing surface.
-
28. The method of claim 19, further comprising updating a position of the writing instrument relative to the writing surface.
-
29. A device, comprising:
-
a housing;
a writing tip connected to the housing;
a writing surface position indicator;
a plurality of accelerometers connected to the housing;
a pressure sensor connected to the writing tip;
a processor in the housing;
a memory device in the housing connected to the processor and having stored thereon instructions which when executed by the processor cause the processor to recognize an interface defined by writing on a writing surface; and
a sensor in the housing and cooperative with the writing surface position indicator. - View Dependent Claims (30, 31)
