Tobii Technology


Tobii Assistive Technology solutions offer an easy to use and truly effective communication for people with highly limited mobility. Tobii AAC products give individuals with communication disabilities a voice and a way to live more fulfilled, integrated and independent lives. A Tobii ATI device can detect precisely where the user is looking on the screen together with a suite of application software which allows the user to communicate and interact using their eyes.

System name(s): Tobii C8, C12, CEye, MyTobii P10, D10

Who can use the system
Target users ALS, Spinal cord injury, Cerebral Palsy, Multiple Sclerosis, Brain injury and others.
What is required from the user Ability to focus gaze on objects on screen for a short (adjustable) duration. The system operates well even if the user has some eye tremor or spasmatic head movements.
Can the system be operated entirely by the user without assistance once the system is setup and running?
Applications within AAC
  • Keyboard substitute (gaze writing)
  • Mouse substitute
  • Internet browsing
