* 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 Eye Tracker 4C works for 97% of the population, making it the most widely compatible eye tracker in the market. It works in a variety of contexts, regardless of eye color, ambient light conditions or use of glasses or lenses.
Yes, it works on curved screens, but we currently do not provide mounting plates that are tuned for them.
The Tobii Eye Tracker 4C works from a distance of 50 –95 cm / 20-37”.
For Tobii Eye Tracker 4C, the maximum screen sizes are
- 27 inches with a 16:9 Aspect Ratio
- 30 inches with a 21:9 Aspect Ratio
We do not recommend that you use a larger screen, especially for the Windows Interaction features, but it works adequately for certain gaming features.
The world’s first eye tracking ASIC and located on the eye tracker, the EyeChip contains all Tobii algorithms necessary for eye tracking computation.
The addition of EyeChip significantly reduces power consumption, CPU load and data transfer between the eye tracker and its host computer
Reviews and reactions
We actually trace what the players are doing […] just look at this! This what you have to be looking at as Counter Strike Pro, guys.
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.
