Are you performing market research and want to know what folks are looking at all day? If you’re able to convince them to wear the Tobii Glasses, you’ll be in a pretty good position to find out. These glasses offer the eye-tracking feature, thanks to a VGA camera at the front, and a hip-mounted unit with SDHC storage, allowing it to store the necessary data. There are IR emitters that are scattered about the field of vision that the researcher is looking to study, which will go some way to tracking what the user is looking at. It’s certainly not something you want to be wearing every day, but if you’re doing some research with it, it does seem like quite a handy piece of kit.
