What is eye tracking and its value in research


Most products today are blind. Eye tracking enables devices to truly see their users, not only by sensing their presence, but also understanding their attention and gaze point.

Eye tracking has a broad range of applications and is already used in a variety of markets:

There are many other markets that could benefit from implementing eye tracking, since the technology can be used to solve various different needs, from safety, to hands-free interactions and training. There’s no limit to the technology’s potential – just imagine what your product could do if it were no longer blind.

Gaming & Entertainment

Play games with your eyes

Eye tracking is already an established technology in PC gaming, with over 100 games available with immersive Tobii Eye Tracking gameplay. It's also used in eSports, making it possible for audiences to better understand how professional gamers play.

VR is another segment where eye tracking is becoming increasingly relevant as a way of enhancing immersion, enabling better graphics and allowing for more natural interactions.

Other uses include interactive displays and slot machines, enabling users to interact and control entertainment product more naturally with just the look of their eyes.

Assessment & Therapy

Eye tracking for research

Eye tracking has been used for research into human behavior for many years. Our business unit Tobii Pro offers a range of solutions for this.

Some fields already rely on eye tracking as an established method to assess:

  • medical conditions such as concussions or certain neurological disorders
  • lie detection
  • a person’s interest and preferences

Eye tracking technology can also be used to treat certain conditions where controlled eye movements can be of importance.

Medical Technology

Robot-assisted surgery can become safer when eye tracking is used to ensure a surgeon is present and looking in the right direction before any action is taken. It also lets the surgeon interact with the robot efficiently with their eyes, since their hands might be busy with other tools. See an example video here

Many types of medical technology products can be improved with eye tracking, by for instance:

  • letting the device know if the operator is present, or looking in the right direction
  • allowing for hands-free interactions and controls
  • recording and documenting how and where a surgeon is looking as a tool for training, assessment or documentation
  • concentrating necessary resources to the area the operator is looking

Industrial Production

Training and assessment of operators and working procedures can greatly benefit from eye tracking by recording and analyzing exactly what the operator pays attention to at different steps of the procedure. This allows new operators to quickly learn from more seasoned professionals. Read more about it here.

Eye tracking can also be used for an user interface where you need to make sure the operator is looking at a specific part of a screen. It can also be used for hands-free interactions when operators might be busy with other tools or instruments, as well as for documentation of operations of critical production steps.

In a control room you can know exactly when and where operators have looked at different monitors.


Tobii Tech Market - Automotive

In Automotive production, eye tracking can be used as in any other industry for training and assessment of operators, for documentation or for critical user interface. 

But eye tracking can also be used inside a car or other vehicles to improve safety, such as by making sure the driver is looking in the right direction (as well as awake and alert) or by allowing for hands-free interactions so the driver can keep their hands on the steering wheel. Read more about this here.
