SteelSeries Splashes E3 with Sentry Eye Tracker, Stratus XL Controller, and Sims 4 Peripherals

Maximum PC: "The key to being a better gamer lies within the eyes, or so that's the basic premise behind a new eye tracking tool by SteelSeries. Developed with the help of Tobii Technology, a major player in eye tracking technology, SteelSeries introduced the Sentry Eye Tracker at E3, which the company describes as a virtual, visual coach that tracks and analyzes eye movement during game play."
