Digital pen Answered

Can  an optical mouse be turned into a PC screen writing gadget or digital pen? Optical mouse have a low resolution camera. By using a software that coordinates what's being shown on the screen and a modified optical mouse, it could be possible to draw on the screen or turn this combination into a touch screen application.

It seems like at the simplest level, you could mount the optical reader head in the end of a pen-type holder and adjust the mouse speed so you could follow the cursor around. The cursor couldn't jump to another spot on the screen, though.

More than that would require some fancy-schmancy software. I'm imagining having every couple of frames (one in sixty?) display a pattern on the screen from which the software could deduce position.

Kind of related.
