How does the IR electronic whiteboard work with a projector or computer?

The IR electronic whiteboard functions as a standard input peripheral. The typical setup operates in a loop:

Display Output: The computer's screen image is sent via an HDMI/VGA cable and projected onto the whiteboard surface by a projector (or displayed by the whiteboard's integrated LCD panel).
Touch Return: When you touch the whiteboard, the IR sensors capture the movement and instantly send the coordinates back to the computer via a USB touch cable.
Plug-and-Play: The USB touch interface is driver-free and works out of the box on major operating systems, including Windows, Android, and Ubuntu (Linux).
