Abstract

An eraser for a presentation board digitiser system includes two or more microswitches 180 in the eraser portion 168 that contacts the board. This allows the system to determine how much of the eraser surface is touching the board, and therefore how much of the display to erase. The microswitches are connected to infra-red or ultrasound transmitters, which transmit the state of the microswitches to the system controller.
