Reviews and reactions

IGN Magazine

“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.”

8.0/10

E League Getting Technical

“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.”

TechAdvisor

“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.”
