Tip: Good lighting and consistent positioning make a big difference to eye gaze accuracy.
eyetutive and Grid 3
As of December 2025, eyetuitive is fully compatible with Grid 3. It is listed as a supported eye tracker, meaning features such as snap-to-item are available. The eyetuitive is identified in Grid 3 as 'GazeFirst' (the manufacturer).
Important: if eyetuitive doesn't appear in Grid 3, please update the device firmware in the eyetuitive app.
Switch Access
Switches can be connected via USB or Bluetooth. Grid 3 allows scanning access, where options are highlighted in sequence until the user activates their switch. Adjust scanning speed, pattern, and auditory feedback under:
