Tele-Graffiti
#1

Tele-graffiti is a technology that allows two or more users to communicate remotely via hand-drawn sketches. What one person writes at one site is captured by a video camera, transmitted to the other site and displayed there using an LCD projector.

The system was developed at Robotics Institute of Carnegie Mellon university, Pittsburg. The system comprises of a digital camera, a high resolution LCD projector to project the received image, a mirror to reflect the projected image onto the paper, fixture to hold these devices in position and a writing pad to fix the sheet of paper on the top of the table at every station.

The user can write on a regular piece of paper with a pen at his desk. The sketch or writing on the paper is captured by the camera and transmits the digitized image to the receiving end through a data link.

The image can be transmitted over the internet or local area network. The software architecture of system runs on Linux and has four threads the drawing thread, the paper tracking thread, sending thread and receiving thread.

Tele-graffiti has various applications. It can play an important role in remote education and remote designing.

It can also serve as a substitute for internet chat. The advantage of the system is that non-computer people can use it. .

Abstract:
 It is a remote Sketching system based on camera-projector.
 The captured images are displayed on the projector.
 It is applied in Teleconferencing and remote Education.
What’s Tele-Graffiti?
• Tele-Graffiti is a system allowing two or more users to communicate remotely with hand drawn sketches.
• A person writing at one site is captured using a video camera, transmitted to the other end.
• Design and implementation of the system
Paper Detection:
• Camera sees the paper and projected image from the previous step.
• Paper detection algorithm had been developed.
(a)The paper is bounded by four edges.
(b)Edges are removed .
©Ambiguous is resolved by the asymmetry between top and bottom of clip board.
Architecture:
Procedure:

• We can place the writing pad any where on the desk.
• Inputs on the pad are appear simultaneously at both ends.
• The camera tracks the edges of paper.
Advantages:
• Multiple users can share the single piece of paper.
• Distance Education will be benefited as students and the teacher.
• Filling web forms.
• It serve as a substitute to Internet Chat.
Conclusion:
• Many innovative reforms and technologies have developed in communication system.
• Many advantages like Tele Conference and Remote Education.
• We can reduce the size of the system and to light weight the systems.
