Portable Board-Style Computer Interface

Whiteboards are generally considered to be an effective tool to assist in the educational and professional industries. With the advancement of technology, interactive whiteboards that use a projector as a screen and a board that registers user input have modernized the concept. However, traditional devices of this type tend to have a high cost, be limited by a fixed boardsize, and must be invasively installed using wall mounts. We created a cost-effective and portable alternative to conventional interactive whiteboards that can be used on many surfaces. By using small infrared sensors to calculate the position of the stylus, we remove the limitation of a predetermined board size, and by adhering to a wall temporarily, the board interface can be set up rapidly. The movement of the stylus in the board will be replicated on the computer.
