Tobii Glasses 2

Researchers and marketers often want to know what catches your eye, whether it's players on the basketball court or just a new shampoo at the store. They may have an easier time figuring this out with Tobii's latest eye-tracking headset, the Tobii Glasses 2. Besides providing a much wider field of view than the original eyewear, the new design has a front-facing 1080p camera that lets observers see whatever you're focused on in real time -- they'll know right away if something gets your attention. The four eye-facing cameras and new software also offer more precise gaze data than the last time around.

As with Tobii's earlier glasses, you won't be buying a personal pair any time soon. At a minimum $14,900 price, the hardware is really meant for product developers, sports teams and others who could easily earn back the expense. All the same, the technology could still make a big impact on your life -- whether it's livelier packaging at the shop or better performance from your favorite athlete.
