Coming soon to a Windows 8 computer near you? Eye-tracking. Available later this year is the “REX” by Tobii, a simple USB-based accessory that attaches itself to the bottom of your monitor. With it, you’ll be able to use just your eyes to navigate your computer. Full details, including exact pricing and availability, should be available soon. There is, however, a developer edition that’s priced at $995.
