For our final project, we want to build a wireless
drawing device. The user uses a keypad or a mouse to draw on the TV through a wireless communication medium (RF - 433.92 MHz). The user should be able to move the drawing pointer to anywhere within the four border lines. One should also be able to draw or erase images on the TV screen.
In designing this project, we have two goals - a primary, which is realizable, and a secondary, which is feasible. Our realizable goal is to build a wireless keypad interface with the television. In this interface, we want the keypad to be able to draw and erase on the TV. When we accomplish our primary goal, we shall attempt to achieve our secondary goal: to build a wireless mouse having the same functionality as the keypad. Due to time constraints, we ended up only being able to complete the primary goal. We chose this project because we were inspired by wireless communication technology.
