You always watched them make those quick and winning moves, without quite knowing the key element behind them - their eyesight. Looking at the right portion of your game screen is the most important part of gaming, and the Sentry eye-tracker lets game-streamers highlight portions of the screen they're looking at. The tracker is a thin black strip that you tuck under your monitor, with optical sensors facing you.

These sensors track your eye movements at 50 frames per second. While it may not be a tracking-device in itself, it lets you place a highlighting overlay, or a PIP inlay window within your stream, which lets viewers see exactly what you're looking at. For those not streaming, the device gives you insights to your gameplay style, letting you improve your reflexes. A live-demo of Sentry was put up at CES, and we can tell you that it works! Available now, the Sentry is priced at 199€.
