Eye-tracking specialists Tobii and video game accessory makers SteelSeries have announced a new partnership to make gaming peripherals that will track players' eye movements.

The companies believe that eye-tracking has the potential to enrich games and "create true immersion," and together they'll release what they say is the world's first mass market eye-tracking peripheral for gamers.

They provide examples like characters in games reacting to your gaze, or being able to move a mini map around without having to take your mouse cursor off the battlefield.

Details on the actual device that will result from this partnership are scarce, but SteelSeries plans to announce more "over the next several months." Unfortunately it doesn't look like we'll see the new tech at CES next week.

X marks the Eye

However, we're not totally in the dark about how the companies' eye-tracking peripherals might eventually take shape.

Tobii said its Tobii EyeX Controller, unveiled in December and being showcased at CES 2014, is a good example of what future eye-tracking products might look like.

The EyeX is a small black peripheral available to developers for $195 (about £118, AU$217) along with a software kit, development framework and working example of eye-tracking software and games.

Tobii has revealed that the full EyeX kit will be available for $95 (about £57, AU$105) at CES or with the coupon code "CES2014."

A focused gaze

Tobii has been hacking away at eye-tracking for a long time.

In 2011 Tobii and Lenovo created a prototype laptop with eye-tracking built in; the same year they revealed the first eye-tracking game, EyeAsteroids.

More recently, it released the first eye-controlled tablet, the Tobii EyeMobile, in 2013.

And at CES last year Tobii unveiled Rex, an eye-tracking add-on for Windows 8.

We'll definitely be keeping an eye on this one. Ha.
