In order to use EyeJustRead an eyetracker needs to be mounted to your computer. A strong magnet is mounted on the lower part of the frame surrounding your screen. Watch the video below, to get a feel for how the mounting is done.
Note: the magnet is hard to remove afterwards.
The EyeJustRead installer will help you through all steps in the installation. When you open EyeJustRead for the first time after the installation, the software needs to know, where exactly the eyetracker is mounted on the screen. This is done by a simple alignment of lines shown on screen and on top of the mounted eyetracker.
Everything is explained in the video below.
