    Getting started using the Game Analyzer


    Can I play all games with the Sentry Eyetracker ?

    For streamers, it’s game on! As long as the game supports a full screen windowed mode, streamers can start showing their viewers where they are looking today. For gamers, tracking your in-game stats and performance will be enabled for Starcraft II and Dota 2 at launch, with many more game integrations in development.

    Is it dangerous for my eyes to use the Sentry Eyetracker ?

    Nope. There are extensive regulatory requirements on biological safety for devices with infrared lighting. The product is well below all threshold values.

    Can I use the Sentry instead of my mouse ?

    While it’s possible to use Sentry without a mouse, it will normally not replace your mouse, but can work as an additional device to enhance your gaming experience.

    Can I be banned for using the Sentry Eyetracker ?

    We haven’t yet seen any gaming regulations around the use of eye trackers.

    Do I need to buy a new Sentry every time a new game is supported ?

    No way. The Sentry’s software will be updated regularly so you won't need to buy a new device to support new games.

    Can I use the Sentry Eyetracker on my Mac ?

    Sorry, The Sentry is not yet supported on Mac OS X. But give us time.

    Can I use the Sentry Eyetracker for my console ?

    The Sentry is not yet supported on consoles.

    Can I place the Sentry Eyetracker somewhere else than under my screen ?

    No, for best results, the Sentry is always supposed to be installed directly under the active area of the screen.

    Can I use the Sentry Eyetracker together with a friend ?

    The Sentry only supports one user at a time, but an unlimited number of user profiles can be installed. Additionally the software installation is not locked down to one PC - so your friend can borrow your device (if you want to let them)..

    Can the Sentry be used with glasses?

    Yes, the Sentry works with most types of eye glasses.
