Telegrafiti is a technology that allows users to communicate remotely through hand drawn sketches. What a person writes on a site is captured by a video camera, transmitted to the other site and displayed using an LCD projector.
The system was developed at the Robotics Institute at Carnegie Mellon University, Pittsburg. The system consists of a digital camera, a high resolution LCD projector to project the received image, a mirror to reflect the projected image on the paper, a device to store these devices in position and a notepad to fix the sheet Paper at the top Of the table at each station.
The user can write on plain paper with a pen on his desk. The sketch of the writing on the paper is captured by the camera and transmits the digital image at the end of the reception through a data link.
The image can be transmitted over the Internet or through a local area network. The system software architecture runs on Linux and has four threads: the drawing thread, the paper tracking thread, the sending thread and the receiving thread.
Telegraphy has several applications. It can play an important role in distance education and remote design.
It can also serve as a substitute for Internet chat. The advantage of the system is that people who are not from the computer can use it.
