What makes TD Control unique?

TD Control’s innovative design allows you to control a computer with your eyes using an intuitive, logical, central interface.

Interaction First

Interact directly - in just one step - with your preferred desktop object. This innovative method of eye control makes interaction faster and more intuitive because there’s no need to use a task bar to select a function first.

Central Interface

After selecting an object via Interaction First, a circle appears center screen. This central interface improves accuracy by placing eye control in the best trackable area of the screen. It also reduces eye travel and fatigue.

Radial Menu

Each command appears in a round button surrounding the central interface. Round buttons and radial menus make it easier to select and focus on the function you want and to minimize incorrect selections.
