Tobii Eye Tracker 4C overview
HERE’S HOW HEAD & EYE TRACKING WORKS
An eye tracker is a hardware component that lets the computer keep track on where
you look. This is done with the help of a combination of projectors and sensors.
Eye tracking has been used in professional contexts for many years. Only recently
has the technology become available to a wider audience, as Tobii has developed
mobile eye trackers for consumer use.
The Tobii Gaming initiative is about enhancing the gaming experience. The eye
tracker makes the computer aware of you, thereby opening up a multitude of possibilities when it comes to creating immersive computer games.
1. An eye tracker consists of cameras, projectors and algorithms.
2. The projectors create a pattern of near-infrared light on the eyes.
3. The cameras take high-frame-rate images of the user’s eyes and their surface
patterns.
4. The image-processing algorithms map specific details in the user’s eyes and
reflection patterns.
5. Based on these details, mathematical algorithms calculate the eyes’ exact
position and gaze point, for instance on a particular spot on the surface of a
computer monitor.
4C – THE GAME CHANGER
Once the computer becomes aware of you, it opens up a whole new type of interaction. With the release of Tobii Eye Tracker 4C, Tobii takes another giant step forward in eye tracking technology for gaming.
The Tobii Eye Tracker 4C is the first PC gaming device to provide head and eye tracking functionality simultaneously. It also sets a new standard for eye tracking devices, thanks to its new Tobii EyeChip.
Gaming is at its best when it provokes flow. No matter where you are physically, in your mind you are deep into a dark jungle, searching for a lost pyramid / far out in another galaxy, trying to outthink your evil enemies in the space trade / running through bombed-out ruins in your WWII outfit / driving a huge truck down a highway ... You’re somewhere, but in your mind, you’re definitely not in front of a computer screen.
A shortcut to flow
The Tobii Eye Tracker helps you get into the flow by adding effects, removing disturbances and letting you interact with the computer in a natural and effortless way. It’s yours to consciously manage, as you use your gaze to aim, pick from a menu or select objects to interact with.
But there’s much more to it than that. The information it provides to the computer can be used to actively tailor the action. For example, depending on where you look, characters or even the environment itself can react to your gaze, light can change and much more. Already, with games like Tom Clancy’s Ghost Recon Wildlands, Dying Light: The Following and Elite Dangerous, plenty of gamers have seen how the added functionality of a Tobii Eye Tracker controller improves their experience. And with its all-new head tracking feature, the Tobii Eye Tracker 4C makes even more immersive gaming possible.
Your head matters
The head tracking functionality means that the tracker detects not only your eye movements, but also how you move your head. Movement data can be used to actively control the game, but it can also be used by the computer as input for making pre-programmed events happen and for other features in the game.
Tobii EyeChip is the difference
The many improvements with the new eye tracker were made possible by the new Tobii EyeChip, the world’s first application-specific integrated circuit (ASIC) developed specifically for eye tracking.
Some stats that changed between the 1st and 2nd generation of eye trackers thanks to the EyeChip are:
• Power consumption: Went from 4.5W down to 1.5W
• CPU Load reduction: Went from 10% down to 1%
• Data transfer: Went from 2GB/s down to 100KB/s
• USB 3.0 connectivity to USB 2.0 connectivity
• Simultaneous Eye and Head Tracking
Log in with a glance
The Tobii Eye Tracker 4C is the first eye tracking device certified for Windows Hello Login. This makes it possible to log on to your computer by just being in front of it. Besides logging on, the Tobii Eye Tracker allows users to interact with their computer using their gaze in different ways (see next page for details). If you have a supported version of Windows, the Tobii Eye Tracker core software will automatically download the Tobii Face Authentication plugin.
Next step in gaming
Tobii Eye Tracker 4C promises to bring you a new kind of gaming experience, no matter what kind of games you play. The Tobii Eye Tracker complements rather than replaces your traditional gaming inputs. It adds new input options and immersion scenarios. In some games, the deeper immersion and a more natural way of controlling the action is the point. In other games, where playing with a game pad is cumbersome or tedious, it lets you navigate simply with your gaze.
No matter the application, the Tobii Eye Tracker is a next step in gaming technology. Try it, and you’ll see for yourself.
