Interactive white board
An interactive whiteboard, also known as a smart board, have the ability to connect to the Internet and instantly digitize tasks and operations.
The technology behind interactive whiteboards varies between large format screens with a standalone system on a chip (SOC) and combinations of video projectors or smart projectors that use a tablet or other devices with drivers for user interaction. Forms of operation are often either by infrared or resistive touch, magnetic or ultrasonic pen. As writing and character recognition is generally digitized, keyboards can be almost completely unnecessary.
Interactive whiteboard software often includes easy-to-use charts, polls and graphs, including virtual versions of tools one might find in a classroom like rulers compasses or protractors. They can play various types of media and provide teachers with interactive lessons for their students.
