I am helping someone that relies on eye tracking.

What should I be aware of when setting up and running an eye tracking system?

What limitations are present? When should I help them? What are typical setup procedures I should be aware of?

Why Eye Tracking

Eye tracking opens up worlds for people that have disabilities that affect their access to a computer.

We live in an information age, but to get the information, you need access to a computer.

As use of a user's hands and wrists deteriorate and even a user's voice starts to diminish, an eye tracker can be a life saver.

Typical Setup Procedure

A typical setup procedure goes as follows:

  1. Call and schedule a demo with a reseller or an AT Center.
  2. Get an eye tracker with a free trial or a rental or as a direct purchase.
  3. Wait for the eye tracker to arrive at your home/institution.
  4. Open the box and read through the included materials (an included Quick Start Guide covers a lot of the information below).
  5. Remove the eye tracker from its packaging, and plug it into a Windows computer, with a single USB 2.0 cable.
  6. Run the installer for the eye tracker included on the EyeTech USB stick (aka jump drive, flash drive, etc).
  7. The software shows an assisted view for lining up the user with the system.
    • Place the eye tracker under the monitor/tablet computer.
    • Having it above the computer usually has issues with eye lashes and eye lids covering up the image of the camera.
    • Sit the user in the working range of the eye tracker.
    • Try to line up the user's eyes close to the center of the live view, so that when they adjust position a few inches in one direction or the other, they remain in view of the camera.
  8. Adjust any settings specific to the user or the setup.
    • Some examples of specific settings include, if they are only going to use the system with one eye as opposed to two.
    • Or if they need more time per calibration target or want to reduce the number of calibration targets used.
  9. Run the Calibration button in the software.
    • This will show a moving target on the screen.
    • Following this target with your eyes, is how the eye tracker is able to associate eye movements to positions on the screen.
    • If the calibration pauses, it is usually if an eye falls off the edge of the screen or if the frames of a pair of glasses are covering up the camera's view of the eye. Sometimes it happens if the user is out of focus.
  10. The eye tracker is now ready to be used in its software!
    • The most common software programs for setup, calibration and use of the eye tracker are QuickACCESS and QuickGLANCE.
    • QuickGLANCE has been integrated into other Speech Generating Device software packages.
  11. Usually after a drastic change in position, or getting up, using the restroom, etc., it is recommended to recalibrate the setup, or at least do a single point calibration update, to recenter the calibration.

Pointing/Moving the Mouse

The motion for moving the mouse/cursor is common across all applications. The speed and responsiveness of the motion is controlled by the software and by top speed the camera can run at.

Click Methods

Clicking is performed by one or more of the following:

  • Blink clicking
  • Dwell clicking
  • Spacebar clicking
  • Enter clicking
  • Hardware Mouse clicking
  • Joystick/Gamepad clicking
  • Switch Mouse clicking

Controls for other Windows Programs

The additional controls for accessing other programs on the windows computer depends on the software installed. Most of the time the minimum amount of control is a left click, a double click, a right click and a click drag. Because a number of programs in Windows have small buttons and small controls, a zoom features aids greatly when the precision of the eye tracker isn't perfect.

How Do I Get More Help / Troubleshooting / Talk to Someone on the Phone

Troubleshooting is quick and easy. If the software isn't giving you the help you need, please, contact the reseller and ask for help with the setup. EyeTech can also be contacted directly if the issue can't be resolved by the reseller.
