Tobii Eye Tracker 4C hands-on: Mousing with your eyes has surprising potential for gaming

Tobii's latest eye-tracking peripheral, the Eye Tracker 4C, refocuses itself on gaming while cutting out some of the cruft that limited its predecessor. Its basic constraints, however, haven't measurably changed. Eye tracking sounds magical: The small, USB-powered 4C "eye mouse" sensor mounts to your monitor, watches your eyes, and "teleports" your cursor to where you're looking. Available for $149 via the Tobii Web site (with a mandatory $25 shipping fee) the 4C is priced at $10 more than its predecessor, the EyeX. The 4C began shipping on December 2. It's a hefty price for a peripheral that essentially supplements your mouse for work and play, though Tobii continues to add features to justify the price tag.
