Assistive Product Eyegaze Edge

Product Type:

Eye control

Areas of Application:

The Eyegaze Edge System from LC Technologies is an alternative input device that enables people with physical disabilities to control a computer with their eyes.


A special one below An (infrared) camera attached to a screen reads the movements of the user and observes the fixation point of the pupil on the monitor.
Here, the eye is illuminated by a small infrared light-emitting diode, which causes several reflections to form in the image: on the retina, on the cornea, as well as further reflections on the edges of the eyelids.
A software specially developed for this purpose continuously calculates both the coordinates of the fixed point and their duration from the reflections on the retina and the cornea. Holding a button displayed on the screen for a longer period triggers a function assigned to the button. The length of stay is adjustable.
By tracking the eye movements by means of a camera system, no additional aids need to be attached to the head or body of the user.
The user must be able to meet the following requirements:
- the ability to control at least 1 eye
- the ability to keep your head still in front of the Eyegaze camera
- some reading and writing comprehension
The room should not be brightly lit, if possible, in order to enable a better evaluation of the infrared light and the system should be set up away from light sources.
