Interactive boards are usually used for the smart classrooms where both teachers and students can learn the lessons interactively through the boards. However, the current prices of these boards are relatively high; 4,500-7,000 USD. This paper proposes an alternatively low cost interactive board usingan infrared pen and a Wiimote. The proposed board consists of an infrared pen, a Wiimote, a projector, a computer and a display screen. The infrared pen createsan infrared spoton the display screen when pressed, whichthen will be detected by the Wiimote. The Wiimote sends the position of the spot on the screen to the computer installed the Wiimote program. Then, the computer converts the infrared spot into a drawing spot as does the regular pen with desired colour while the resultant spot is shown on the screen via the regular projector. The proposed interactive board has an approximately price up to 2,500 USD, which is1.8-2.8 times less expensive compared with the commercial boards.
