Title: e-Desk - A Pen Based Information Digitizing and Collaboration Platform


This disclosure discribes the design and implemention of a unique user ID enabled pen, the supporting digitizing device, which can be mounted below any hard surface, e.g. a desk , as well as related supporting firmware, software and applications, to make pen based information digitizing and sharing natural and effective.


The e-Desk invention includes three parts:

1. A special purpose 'e-pen', besides its ability on normal paper writing, can emit pen movement signals and user ID information for digitizing device to capture during the writing procedure. thus making the multi-user information collecting and sharing feasible.

2. A kind of low-cost, thin digitizing device - 'e-surface', as well as related firmware that can be embedded in any nonmetal, hard-surface objects,e.g., a desk, to act as a pen movement and user identity collection device.

3. A location-centric user interest detector, fully customized by software, can accomplish the user tailored functions such as schedule reminder, user's memo, signature tablet, handwriting fax etc, for each user.

We call all the three parts "e-desk" as a whole. By fixing the e-Surface to specific areas, and using e-Pen with userID, many novel effective applications are generated. e-Pen is the only thing each user need to take for many information digitizing and sharing tasks.

The hardware parts of this invention - e-Pen and e-Surface are based on the digitizing device of IBM ThinkScribe(TM). The e-Pen is built by adding a RF IC, which act as the unique user ID, to the IBM ThinkScribe pen, the detailed implementataion information of IBM ThinkScrible digitizing device and pen can be found in[1][2]. The digitizing hardware , e-Surface , is built by first adding a RF transceiver to the former digitizer for user identity retrieval, second building the sensor for capturing pen movement signals on certain soft, thin material by cluing foil metal, thus make it possible to be embedded under any hard surface.

With the user ID enabled pen and digitizing hardware, many novel applications can be built on it, The following are some examples.

Potential application & user scenarios

In this part, we will enumerate some user scenarios as well as some application level inventions depending on our pen-based information digitizing and collaboration platform.
