Abstract

Remote collaboration, particularly synchronous collaboration, between parties in separate locations can be enhanced by providing the opportunity for both parties to “write” on a paper medium or other surface. This is particularly useful in an instructor/student tutoring session. Both the student and instructor may have workstations with video conferencing and screen-sharing capabilities. Advantageously the student station has a camera such as a document camera for imaging an object that the student may write on, for example, writing on paper with a pen. The instructor station may have an interactive whiteboard and a projector. Video conferencing capabilities are used to transmit an image of the student writing to the instructor which image will be displayed to the instructor through projection onto an interactive whiteboard surface. The interactive whiteboard allows the instructor to “virtually” mark the projection of the paper using for example a stylus and an infrared sensor. Annotation software at the instructor'"'"'s station creates a representation of the instructor'"'"'s “writing.” The annotation software also may add the representation of the writing to the instructor'"'"'s projection. The representation of the writing and the representation of the image are provided to the student station by the screen-sharing software and the combined document image and annotations may be displayed to the student creating the effect of the remote instructor writing on a paper locally imaged by the document station.

Claims

1. A virtual writing station comprising:

a personal computing platform having a video conferencing subsystem, a first display associated with said video conferencing subsystem, an annotation subsystem, a screen-sharing subsystem associated with said annotation subsystem, and a second display associated with said screen-sharing subsystem;

an interactive whiteboard connected to said annotation subsystem; and

a projector connected to said personal computing platform;

wherein said personal computing platform is configured to receive an image over a communication link from a remote station, provide the image to said projector;

transmit annotations generated from inputs from said interactive whiteboard to said remote station and combine said annotations and said image.

2. A virtual writing station according to claim 1 wherein said interactive whiteboard further comprises a virtual writing implement and a sensor detecting actions of said implement.

3. A virtual writing station according to claim 2 wherein said virtual writing implement is a stylus and said sensor is an infrared sensor.

4. A virtual writing station according to claim 1 wherein said screen-sharing subsystem is configured to combine and share said annotations and said image provided to said projector with a remote station.

5. A virtual writing station according to claim 1 wherein a personal computing platform is configured to provide said annotations to said projector.

6. A virtual writing station according to claim 5 further comprising a camera, a speaker, and a microphone connected to said video conferencing subsystem.

7. A virtual writing station according to claim 6 wherein said personal computing platform is configured to execute a video conferencing session and a screen-sharing session with a remote station.

8. A virtual writing system comprising:

a virtual writing station having;

a personal computing platform having a video conferencing subsystem;

a first display associated with said video conferencing subsystem;

an annotation subsystem;

a screen-sharing subsystem associated with said annotation subsystem; and

a second display associated with said screen-sharing subsystem;

an interactive whiteboard connected to said annotation subsystem;

and a projector connected to said personal computing platform;

wherein said personal computing platform is configured to receive an image over a communication link from a remote station, provide the image to said projector, transmit annotations generated from inputs from said interactive whiteboard to said remote station, and combine said annotations and said image;

a second station connected by a communication channel to said writing station wherein said second station is remote from said writing station and includes a remote personal computing device having a remote video conferencing subsystem, a remote screen-sharing subsystem and a second remote display linked to said remote screen-sharing subsystem;

a remote camera connected to said remote video conferencing subsystem;

wherein said remote personal computing device is configured to transmit one or more images captured by said remote camera from said remote video conferencing subsystem to said video conferencing subsystem of said virtual writing station; and

said remote screen-sharing subsystem is configured to receive video information from said screen-sharing subsystem of said virtual writing system and display said video information on said second remote display.

9. A virtual writing system according to claim 8 wherein said second station further comprises a remote display connected to said remote video conferencing subsystem.

10. A virtual writing system according to claim 8 wherein said interactive whiteboard further comprises a virtual writing implement and a sensor detecting actions of said implement.

11. A virtual writing system according to claim 10 wherein said virtual writing implement is a stylus and said sensor is an infrared sensor.

12. A virtual writing system according to claim 8 wherein said screen-sharing subsystem is configured to combine and share said annotations and said image provided to said projector with a remote station.

13. A virtual writing system according to claim 8 wherein a personal computing platform is configured to provide said annotations to said projector.

14. A virtual writing system according to claim 13 further comprising a camera, a speaker, and a microphone connected to said video conferencing subsystem.

15. A virtual writing system according to claim 14 further comprising a remote camera, remote speaker and a remote microphone connected to said remote video conferencing subsystem.

16. A virtual writing system according to claim 15 wherein said personal computing platform is configured to execute a video conferencing session and a screen-sharing session with said second station.
