Interactive whiteboards are advanced versions of traditional whiteboards that can be plugged into a computer and projector to display the computer screen. They are interactive through touch, allowing a pen or finger to control the board like a mouse or keyboard. Interactive whiteboards were originally developed in 1987 and introduced an interactive technology to classrooms and meetings. They can be used for presentations, teaching lessons step-by-step, and engaging student learning across various subjects through interactive activities and internet access.
