School is the place to learn new and fundamental things, where one discovers and further enhances ones abilities. Through time, teaching methods have become more efficient and convenient – from the old black board and chalk; teachers now have the help of computers and projectors. In today’s fast paced world, things are not permitted to stay old and technology must continuously progress and adopt to keep up. Things are innovated in time to further make life easier and computers serve that purpose. Teachers nowadays are inclined to the usage of computers and projectors. Keeping that in mind, the group had the idea of further enhancing the efficiency and utility of the said devices. The system that was theorized would have three parts which include an infrared pen, a camera system which is connected to a protoboard, and the software that would be responsible for the inputs and outputs of the system. The use of the infrared pen is like that of the mouse of a computer and basically consists of infrared light-emitting diodes and a switch. The pen would provide the left click function of the mouse and by clicking it one would be able to drag, drop and select things which are projected by the projector. While as the camera system is responsible for retrieving the position of the infrared light emitted by the infrared light-emitting diode. The data collected by the camera would be sent to the protoboard which would then be connected to the computer via USB. The two said devices would need a voltage converter to ensure that they can communicate with each other via signals, thus a voltage converter would be added to the whole module. With all devices set and data signal received by the computer, the software would then compute necessary parameters and deliver the corresponding output.
