An interactive whiteboard, called a SMARTboard, connects to a computer and projector to display the computer desktop. Users can control applications by touching the board with their finger, like a mouse. SMARTboards were introduced in 1991 and allow teachers to deliver engaging lessons where students can interact with classroom content. The board requires a computer, projector, and SMARTboard software to annotate and save notes. Costs include the SMARTboard itself, a projector, and computer, with training available through workshops.
