Designed for AAC

All the features of Lumin-i have been developed with AAC users in mind.

We know how important it is that you have a reliable and accurate access method that you can use anywhere.

Large track box
The large track box (35 x 30 x 65 cm) maintains your gaze even if you have some involuntary head movement, change your position, tilt your head to one side or move back and forth.

Exceptional recovery rate
A recovery rate of just 17 ms (milliseconds) ensures seamless communication. If you turn your head to the side or look away briefly, your gaze will be instantly re-established.

Any lighting conditions
Developed to work in any lighting conditions, Lumin-i gives you access to your communication aid anywhere.

Excellent outdoor performance

Lumin-i is one of the best eye trackers available for outdoor use. High-powered infrared emitters bring you reliable and steady eye tracking, even in bright conditions.

Coupled with the antiglare coating on your Grid Pad display, Lumin-i provides consistent eye gaze access in all environments.

Optimised for Grid AAC software

Lumin-i has been specifically designed for use with our industry leading Grid AAC software, so you don’t need to worry about any additional software packages.

Everything is built into Grid, making it even easier to get started.
