SpotCode
High Energy Magic is pushing something called SpotCode, which they're describing as software for turning a cameraphone with Bluetooth (which are a lot more common in Europe than here) into a mouse. It's probably a bit disingenuous to say that SpotCode can really turn a cameraphone into a mouse, since all it does is let you select something on a screen and rotate virtual knobs, not move a cursor around like you'd expect/hope. We don't doubt that it works, and it's a neat-o proof-of-concept, but you could achieve the same level of interactivity by installing a regular old touchscreen instead — plus you wouldn't have to mess around with Bluetooth or require anyone who wants to use the screen to own a cameraphone. So when you think about it, this really just a slightly fancified version of
SemaCode, that barcode reading software for cameraphones we all got excited about a few weeks back.
