Eye Gaze Systems
Eye gaze systems allow people with severe physical disabilities to access a computer. These high-tech systems have an inbuilt camera which tracks where your eyes are looking, enabling you to move the mouse pointer around. You can 'click' by blinking, dwelling (staring at the screen for a certain length of time) or using a switch.
We have a range of eye gaze systems available, and we recommend that you try them all out in an assessment. Different people find that different systems are more effective for them. We will always try to find the best system for an individual, and having a range of options helps us to do this.
If you are using mouse-control mode, you have the potential for much greater accuracy, but this can be more difficult for some people as you are effectively moving the mouse pointer pixel by pixel.

Head Movement
The Alea, CEye and TM4 all allow for a certain amount of head movement, with the Tobii CEye having the largest track box available. The "track box" is the term used to describe the space you have available within which to move your head. The LC Edge can be a great (and slightly cheaper) option for those with very limited head movement.Access Options
All these systems are fully integrated with The Grid 2, which provides several options for calibration and tracking. If you are using The Grid 2, the targets (or cells) are easy to select as there is a larger surface area to hit.If you are using mouse-control mode, you have the potential for much greater accuracy, but this can be more difficult for some people as you are effectively moving the mouse pointer pixel by pixel.
