Abstract

A data capturing system is provided. The data capturing system includes a digital pen and a color-coded medium. The color-coded medium contains color information. The digital pen is able to detect the color information and to determine at least one field information of the color-coded medium based on the detected color information when it moves over the color-coded medium.

Claims

1. A data capturing system comprising:

a digital pen; and

a color-coded medium having color information thereon,

wherein the digital pen is able to detect the color information and determine at least one field information of the color-coded medium based on the detected color information when it moves over the color-coded medium.

2. The data capturing system of claim 1, wherein the digital pen comprises

a color sensor;

and

a processor,

wherein the color information of the color-coded medium is detected using the color sensor, and

wherein the field information of the color-coded medium is determined using the processor.

3. The data capturing system of claim 2, further comprising a position sensing system for determining a position of the digital pen.

4. The data capturing system of claim 3, wherein the position sensing system comprises:

an electromagnetic transmitter mounted on the digital pen; and

an electromagnetic sensor,

wherein the electromagnetic sensor detects an electromagnetic signal transmitted by electromagnetic transmitter and determines the position of the pen based on the detected electromagnetic signal.

5. The data capturing system of claim 3, wherein the position sensing system comprises:

an acoustic transmitter mounted on the digital pen; and

an acoustic sensor,

wherein the acoustic sensor detects an acoustic signal transmitted by the acoustic transmitter and determines the position of the pen based on the detected acoustic signal.

6. The data capturing system of claim 5, wherein the acoustic transmitter is an ultrasonic transmitter for transmitting an ultrasonic signal, and the acoustic sensor is an ultrasonic sensor for receiving the ultrasonic signal.

7. The data capturing system of claim 2, wherein the color sensor is a Red Green Blue (RGB) sensor.

8. The data capturing system of claim 2, wherein the digital pen further comprises an ink forming element for forming a mark on the color-coded medium when the digital pen moves over the medium.

9. The data capturing system of claim 2, wherein the digital pen further comprises a connection means for transferring data from the digital pen to another device.

10. The data capturing system of claim 9, wherein the connection means comprises a Bluetooth connection.

11. The data capturing system of claim 9, wherein the connection means comprises a Universal Serial Bus (USB) connection.

12. The data capturing system of claim 1, wherein the color-coded medium is a paper having a plurality of colors printed thereon.

13. The data capturing system of claim 12, wherein the color information of the color-coded medium is a combination of at least two colors for each field of the medium.

14. The data capturing system of claim 13, wherein an identity of the medium is determined based on a sequence of color combination for each field of the color-coded medium.

15. A digital pen for capturing data from a color-coded medium having color information thereon, the digital pen comprises:

a color sensor for detecting the color information of the medium when the digital is moved over the medium;

a position signal transmitter for transmitting a position signal to a receiver; and

a processor for determining at least one field information of the medium based on the detected color information.

16. The digital pen of claim 15, wherein the position signal transmitter is an electromagnetic signal transmitter for transmitting an electromagnetic signal.

17. The digital pen of claim 15, wherein the position signal transmitter is an acoustic signal transmitter for transmitting an acoustic signal.

18. The digital pen of claim 17, wherein the acoustic signal transmitter is an ultrasonic signal transmitter.

19. The digital pen of claim 15, wherein the color sensor is a Red Green Blue (RGB) sensor.

20. The digital pen of claim 15, further comprising an ink forming element for forming a mark on the medium when the digital pen moves over the medium.

21. The digital pen of claim 15, further comprising a connection means for transferring data from the digital pen to another device.

22. The digital pen of claim 21, wherein the connection means comprises a Bluetooth connection.

23. The digital pen of claim 21, wherein the connection means comprises a Universal Serial Bus (USB) connection.

24. A method for capturing data from a color-coded medium having color information thereon using a digital pen, the method comprising:

detecting the color information of the medium when the digital pen is moved over the medium; and

determining at least one field information of the medium based on the detected color information.

25. The method of claim 24, further comprising:

determining a position of the digital pen;

determining movements of the digital pen based on the determined position of the digital pen; and

associating the movements of the digital pen with the filed information of the medium.
