The Promethean TDS ACTIVboard is based on tried and tested digitiser technology. TDS PROMETHEAN have designed and manufactured digitisers for over 20 years. The TDS ACTIVboard uses electro-magnetic sensing technology. A small magnetic field is created over the surface of the board which the TDS ACTIVpen reacts to and then reflects the signal back to the board. The ACTIVpen supports both left and right mouse clicks. Interactive whiteboards are a revolutionary way to share information on your PC with your customers, colleagues or pupils in the boardroom, command centre or classroom, etc. By connecting a standard Windows based PC, portable projector and a TDS ACTIVboard you have a powerful information tool, easily controlled by the ACTIVpen, which works in exactly the same way as the PC mouse.
