How do I control my computer through the interactive whiteboard?

On membrane boards such as SMART every time you touch the surface with your finger the computer interprets the touch as a 'left mouse click' enabling you to move your mouse around the screen, open programs and do basically everything you could do before with your mouse. On SMARTboards a right mouse click is achieved through first pressing a button on the tray below the screen and then touching the board.

On other boards using electro-magnetic technology simply touching the boards will not work, these boards need to be touched with a special pen that gives you the function of left and right mouse clicks. Electro-magnetic technology gives you extra security, as the board cannot be used without the pen however the usability is exactly the same as the membrane technology boards just a different input interface.
