TD Control

TD Control is an intuitive way of interacting with and controlling your computer via eye tracking. It’s designed for people with conditions such as cerebral palsy, ALS/MND and spinal cord injury who cannot use their hands but want full, independent use of their computer. Navigate and control the Windows environment in a natural way. Use the software and websites of your choice. Stay connected via email and social media. Play your favorite games. Read best sellers. Watch the latest shows. Unleash your creativity. TD Control lets you start as an eye gaze novice and progress easily to control your computer completely using just your eyes.

Included with all TD I-13 and TD I-16 devices and PCEye 5 eye trackers. Currently unavailable to purchase as a standalone app.


Your computer, your way

Customize your experience

Designed for eye gaze novices and experts alike, TD Control lets you start wherever you are comfortable and progress at your own pace to more advanced skills. It also enables you to customize your experience by showing only the icons you use most and want to see.

Broaden your horizons

Read, watch, edit pictures or video, code, and game with your eyes. Creative outlets also make excellent eye gaze practice. By right clicking, single left clicking or simply interacting with others onscreen, gaming for example, is a great way to learn eye tracking skills.

How to get it

TD Control comes pre-installed and is currently available only on the TD I-Series—a fast, durable gaze-enabled speech generating device, and the PCEye—a compact, flexible eye tracker. Both devices feature the world’s most advanced assistive eye tracker.

What makes TD Control unique?

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

Natural interaction

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 or to plan your actions to select a function first.

Improved accuracy

After selecting an object, a zoomed-in image of the target 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.

Easy on the eyes

Navigate and control your Windows environment in a natural way, minimizing eye travel which reduces fatigue. 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.
