Laurent Giraldon and Nicolas Riber listened intently to understand how this technology allows us to know exactly what we are looking at and how we can use our gaze as a 3rd hand either in a virtual reality helmet or in front of a screen.
Did you say “eye tracking”?
Sight is the basic sensation with which we perceive the world around us. Eye tracking (or oculometry in French) allows you to measure where a person is looking. Thus, this technology allows you to understand and characterize behavior through visual perception. It is at the Pico Interactive stand that Antoine Lou presents the experience of Tobii, this Swedish group that specializes in eye recognition. Originally, this technology, born about fifteen years ago, allowed a machine weighing about twenty kilograms to detect the area where your gaze is on the screen. In the fight for miniaturization, this technology is now presented in the form of a small 100-gram bar that plugs into a USB port. The technology is now available directly in virtual reality headsets from major brands such as HP, Pico, HTC Vive or Lynx, the future French headset. Similarly, a group of more than 1,000 people equips computers such as DELL, MSi or Asus for professional use. Thanks to this technology, we can now evolve in these virtual environments, just like in life. Almost on the third hand thanks to your eyes The idea of this solution is to do without the mouse or complement the mouse when using the screen or headset. In fact, you can literally take the camera in first person and move without having to manipulate the joystick, mouse or keyboard. In gaming, this gives us superpowers: you can have “revolver” eyes, like in a song, and knock out your opponents just by looking at them.
Useful technique for people with disabilities
Another program: people with disabilities are now in double danger when they have to communicate, because everything is done while browsing the Internet, and if you can’t type on keyboard keys or control a mouse, it becomes difficult. Today, more than 100,000 people worldwide use Tobii technology to browse, write and communicate online with the naked eye. Looking becomes an order, an instruction.
Application in e-sports
The dream of any e-coach is to conduct a poll of players correctly – to see exactly what players see at the moment: now this is done by installing the application “Tobii Ghost”, coaches can put themselves in place of players. A small digital cloud is superimposed on the screens, which allows coaches to follow this artifact, which symbolizes the vision of the players. Therefore, the coach can analyze the course of eye vision in games. Antoine Lou launches the program, and a few seconds after looking at the asteroids, the Tobii panel will work. In addition, Antoine shows us Tobii Ghost, which allows you to display the player’s face in 3D, the same, but in addition, the avatar’s head reacts in the same way as the movement of the head and the player’s gaze.
Used in medicine or to navigate the orientation map
This technology is also used in radiology: for example, if a surgeon operates and needs both hands for surgery, he can enlarge an X-ray or medical image with just one glance. By the same token, if you look at an interactive map of the city, you can zoom in by keeping it in the area. To move, all you have to do is look at the street you want to take and the map will go, it’s all done naturally, even you can easily scroll the carousel of images, looking at the navigation arrows.
Application for safety in autonomous vehicles
Thanks to his work on the Driver Monitoring System, Tobii also works for our safety when we are on board autonomous vehicles. Because despite the direction of our gaze, Toby also sees the size of our pupil. Expands or contracts when the machine offers to transfer control to a person on board. Its size will determine the level of our attention to the road, it is not about getting behind the wheel if we are in a state of confusion, fatigue or cognitive stress.
