IR (Infrared) Interactive Whiteboards – TDD-IWB-IR
TDD-IW-IR (Infrared) Interactive Whiteboard has infrared transmitters and receivers, which linked to a USB main board and fixed inside rigid aluminum frames, forming a square scanning infrared ray net on the surface when connected to a computer by USB cable. When a finger or other non-transparent object touches on the surface, this touching point’s coordinate (x, y) is immediately transmit to the main board and forms a corresponding PC operation.
Meanwhile, the panel itself is free of technology, guaranteeing longer life time than any other types of interactive whiteboards. Four points touch bring maximum four students collaboration at the same time. Teachers can design more interactive lessons and students will be even more engaged in the learning process.
