Abstract

An electronic pen for interacting with a substrate having a pattern of coded data printed thereon. The pen includes an infrared light source for illuminating an area of the substrate; an image sensor for imaging the coded data illuminated in the area; a force sensor for sensing an interaction between the pen and the substrate; a processing system configured for: determining digital ink from the imaged coded data; storing the digital ink in a memory buffer; determining whether the pen is positioned within a predetermined functional zone of the substrate; and initiating a response in the pen in the event that the pen is positioned within the predetermined functional zone. The response is initiated without reference to a remote computer system.

Claims

1. An electronic pen for interacting with a substrate having a pattern of coded data printed thereon, said pen comprising:

an infrared light source for illuminating an area of the substrate;

an image sensor for imaging at least some of the coded data illuminated in said area when the pen is used to interact with the substrate;

a force sensor configured to sense interaction between the pen and the substrate;

a processing system configured for;

determining digital ink from the imaged coded data, said digital ink comprising a sequence of pen positions representing handwritten information;

storing the digital ink in a memory buffer;

determining, from the imaged coded data, whether said pen is positioned within a predetermined functional zone of said substrate; and

initiating a response in said pen in the event that the pen is positioned within the predetermined functional zone,

wherein the response is initiated without reference to a remote computer system.

2. The electronic pen of claim 1, wherein said processing system is configured for recognizing a flag contained in the coded data within said predetermined functional zone.

3. The electronic pen of claim 1, wherein the response provides feedback to a pen user regarding the predetermined functional zone.

4. The electronic pen of claim 1, wherein said processing system is further configured for sending the digital ink to the remote computer system when said pen is in communication with said remote computer system.

5. The electronic pen of claim 1, wherein said pen comprises a transceiver for wireless communication with said remote computer system.

6. The electronic pen of claim 1, wherein said processing system is configured for determining a yaw of the pen relative to the substrate.

7. The electronic pen of claim 1, wherein said processing system is configured for determining a two dimensional perspective transform using the imaged coded data.

8. The electronic pen of claim 1, wherein said pen contains a pen identifier, said identifier distinguishing the pen from other pens of the same type.
