How is a SMART Board an input device?

The SMART Board comes equipped with four markers and an eraser. These markers, also known as plastic pen tools, allow the teacher, student, or user to work interactively with a computer. The user can also use their finger to serve as a mouse on the screen.

The pen tray that is located on the front of the board at the bottom is where the plastic pen tools are located. When the pen tool is removed from its home location in the pen tray, an optical sensor will detect the absence of the pen. The SMART Board will recognize the pen’s contact with the board, and allow you to write on the screen. The board is so smart, that it will allow you to use even your finger to write, so long as there is a pen removed from the tray. When the eraser is removed from the tray, the SMART Board allows you perform an erasing function, whether it is with your hand or the actual eraser, the board will follow whatever command is given THROUGH the pen tray.
