Boasting incredibly accurate head and eye tracking, a built-in eye-tracking ASIC that improves tracking and negates CPU load on the PC and an impressive number of AAA games offering support, the 4C really is a winner.

Where [the Tobii Eye Tracker 4C] really shines is in games. It’s a wonderful compromise offering extra immersion without having to don an expensive VR helmet.

* Head tracking is not powered by the EyeChip so it may increase your CPU load. ** The average power consumption during usage is 2.0W, but the eye trackers power consumption can spike up to 5-6W depending on the use case. For example, when the illuminators first turn on, the consumption can briefly spike (matter of milliseconds) at around 5-6W. The Tobii Eye Tracker 4C officially works with USB 2.0 BC1.2 which can handle spikes up to 7.5W. *** The tracker is compatible with Windows 7 and 8.1, but we no longer perform tests on these versions so we can’t guarantee functionality in our newer software releases.
