Abstract

A pen has a marking device operative to mark a visible path onto a surface. The marking device is electronically controllable to change at least one of the attributes of the path. The attributes are constituted by the characteristics of the ink being deposited and can include the amount of ink deposited, the width of the line produced, and the color of the ink deposited. The pen also includes a user interface provided by one or more potentiometers or control buttons such that the user may modify the attributes. Additionally, the pen may include a display to indicate the selected attributes to the user and a sensing device for sensing coded data.

Claims

1. A pen including a marking device operative to mark a visible path onto a surface having coded data disposed thereon, the marking device being electronically controllable to change at least one attribute of the path, the pen including at least one sensor device capable of sensing at least some of the coded data when placed operatively relative to the surface, the pen being adapted to control the marking device at least partially with reference to at least some of the sensed coded data to modify at least one attribute of the path.

2. The pen of claim 1 further including a decoder adapted to decode at least some of the sensed coded data to form decoded data and to cause the marking device to change the at least one path attribute at least partially in response to the decoded data.

3. The pen of claim 1 including a receiver for receiving commands from an external control source, the pen being adapted to cause the marking device to change the at least one path attribute in response to said received commands.

4. The pen of claim 1 further including a memory for storing sets of path attributes.

5. The pen of claim 1 further including a receiver for receiving at least one path attribute from an external control source.

6. The pen of claim 5 further including a memory adapted to store at least one user-defined set of path attributes.

7. The pen of claim 1 or claim 2 further including a transmitter adapted to transmit sensed coded data or decoded data to an external control source.

8. The pen of claim 7 wherein the pen has a position relative to the surface and wherein, in use, the pen transmits one or both of the sensed coded data and the decoded data to the external control source together with at least one value of the at least one attribute of the path at the position of the pen.

9. The pen of claim 1 including at least one of a position sensing device and a motion sensing device and wherein the at least one attribute of the path is dependent on at least one of the position of the pen and the movement of the pen relative to the surface.

10. The pen of claim 9 wherein the movement of the pen relative to the surface is at least partially derived from the position of the pen relative to the surface.

11. The pen of claim 9 wherein at least one of the position and the movement of the pen relative to the surface is derived at least partially from at least some of the sensed coded data.

12. The pen of claim 1 wherein the marking device comprises a printhead.

13. The pen of claim 12 wherein the printhead comprises an ink ejection type printhead.

14. A pen comprising:

(a) an electronically controllable marking device adapted to apply a mark to a surface, the marking device having at least one mark application attribute and being adapted to modify the at least one mark application attribute in response to receiving an attribute modification instruction;

(b) a sensor which, when placed operatively relative to a surface having coded data disposed thereon, is adapted to sense at least some of the coded data; and

(c) a processor adapted to;

(i) receive sensed coded data from the sensor;

(ii) generate indicating data using at least some of the sensed coded data, at least some of the indicating data being at least partially indicative of at least one mark application attribute; and

(iii) provide at least one attribute modification instruction, associated with the indicating data, to the marking device,

thereby causing the marking device to modify the at least one mark application attribute.

15. The pen of claim 14 further comprising a memory adapted to store at least one attribute modification instruction.

16. The pen of claim 15 wherein the processor is further adapted to locate, in the memory, at least one attribute modification instruction associated with the indicating data before it provides the at least one attribute modification instruction to the marking device.

17. The pen of claim 14 further comprising a communications transmitter and a communications receiver adapted to facilitate communication between the pen and an external computer.

18. The pen of claim 17 wherein the processor is further adapted to provide the indicating data to the external computer via the communications transmitter.

19. The pen of claim 18 wherein the processor is further adapted to:

(i) receive attribute modification information from the external computer via the communications receiver; and

(ii) identify at least one attribute modification instruction at least partially associated with the attribute modification information,

before it provides the at least one attribute modification instruction to the marking device.

20. The pen of claim 14 wherein the marking device is an ink ejection type printhead.

21. The pen of claim 20 wherein the mark application attribute defines the way in which the ink ejection type printhead applies a mark to a surface.

22. A method for controlling a pen, the pen comprising an electronically controllable marking device, a sensor and a processor, wherein the method comprises the sensor performing the steps of:

(i) sensing at least some coded data from a surface having coded data disposed thereon; and

(ii) providing the sensed coded data to the processor, the processor performing the steps of;

(i) receiving the sensed coded data from the sensor;

(ii) generating indicating data using at least some of the sensed coded data, at least some of the indicating data being at least partially indicative of at least one mark application attribute; and

(iii) providing at least one attribute modification instruction;

at least partially associated with the indicating data, to the marking device, and the marking device performing the steps of;

(i) receiving the at least one attribute modification instruction from the processor; and

(ii) modifying at least one mark application attribute of the marking device in accordance with the attribute modification instruction.

23. The method of claim 22 wherein the pen further comprises a memory adapted to store at least one attribute modification instruction and wherein the processor performs the additional step of locating, in the memory, at least one attribute modification instruction at least partially associated with the indicating data before providing the at least one attribute modification instruction to the marking device.

24. The method of claim 22 wherein the pen further comprises a communications transmitter and a communications receiver adapted to facilitate communication between the pen and an external computer, the external computer being located outside the pen, and wherein the processor performs the additional steps of:

(i) providing the indicating data to the external computer via the communication means;

(ii) receiving attribute modification information from the external computer via the communications receiver; and

(iii) identifying an attribute modification instruction at least partially associated with the attribute modification information,

before providing the at least one attribute modification instruction to the marking device.

25. The method of claim 22 wherein the marking device is an ink ejection type printhead.

26. The method of claim 25 wherein the mark application attribute defines the way in which the ink ejection type printhead applies a mark to a surface.

27. The method of claim 22 wherein the sensor performs the step of sensing at least some coded data when the sensor is placed operatively relative to the surface.
