a little project for my lab, a mouse that knows at which distance you’re from it. We would like to explore if this information could be relevant for the system e.g. to highlight the cursor when you approach your mouse or to tell background operation to interrupt in order to release CPU for interaction…

he is using a LDR for the 0 to 4 cm and a Sharp 2D120 IR range finder for 4 to 50 cm. The arduino code on the flickr page.
