LAS VEGAS — Tobii has been learning how to track your eye movements for the last 15 years. A few years ago, the company added its eye-sensing camera technology into a prototype laptop.

Now, at CES, the company showed off a consumer-ready MSI gaming laptop with its latest eye-tracking sensor.

I tried a demo of a modded version of Grand Theft Auto 5, where I fired rockets at enemies and vehicles, and it blew me away.

The laptop, the GT72 Dominator Pro Tobii, is a typical clunker of gaming machine. It's got a large screen, a backlit keyboard that glows in a rainbow of colors, and even an optical drive. A svelte Ultrabook it definitely isn't.

The marquee feature, of course, is the Tobii eye-tracking sensor bar that's built into the hinge. The sensors can accurately track your eye movements. Tobii is partnering up with Ubisoft to let gamers aim, shoot and zip line in Assassin's Creed Syndicate using their eye movements.

I didn't get to try it with Syndicate, but I did try it with a modded version of GTA 5.

After a very quick calibration, I was able to control the camera movement (normally mapped to the right analog stick) and aim at enemies simply by looking at them. Firing rockets still required the use of a game controller.

Still, I felt like Superman annihilating things with my eyes. The eye-tracking was fast and accurate and felt natural. I'll be the first to admit that I'm not great at games where you have to constantly adjust the camera view with the controller, but I got the hang of using my eyes instantly.

I feel confident that my mom, who is deathly afraid of modern video games, could pick up the eye-control system in seconds.

When I asked a Tobii representative how difficult it is to add eye-tracking to games and apps, I was told it isn't difficult at all. Apparently Ubisoft developers were able to get it working with Syndicate within a few days.

MSI's laptop is the first one with Tobii's eye-tracking technology and it'll be out within the first half of the year. If more developers jump on board with eye-tracking controls, it could pave the way for more PC makers to integrate it into their machines.

The sensor is rather bulky, and it needs to slim down significantly to fit into thin and light Ultrabooks. But when that happens, eye-tracking could be a viable alternative to touchscreens and trackpads.
