This project is for professors who uses both a projector as well as a board simultaneously to teach. This device will help you to substitute both your boards into a single board. As the name suggest it’s controlled by infrared sensors to detect the movement of an IR led to control the remote laptop. In the whiteboard mode, the user can interact with a projected image to do things like scrolling, changing the image while in the blackboard mode the user will be able to write on a blackboard and have the IR camera trace the movements and draw it on paint and save the images
The IR camera used is from the WII remote which is quite potable but still provides HD resolution and can track up to 4IR sources simultaneously. Since the camera is not available as a ready to buy unit, you will have to carefully remove it from the Wii remote. The information is transmitted with the help of RF operatred at 433 Mhz and the microcontroller is used is Atmega128p. On the laptop side, the required data is send to Matlab which then processes it to make the required changes on the laptop. A different project but a costly due to the presence of an IR camera and Matlab.
