3.2.2.1 Eye Tracker Setup with a Tripod
Please take the following steps to adjust the eye tracker if it is mounted on a
tripod.
1) The Display PC monitor should be set such that when the participants are
seated and looking straight ahead, their eyes are level with the top quarter of
the monitor.
2) Ideally the camera should be placed at a distance of about 50-55 cm from
the participant's eyes. This means that if you are using a monitor smaller
than 20'', the eye tracker can be placed right in front of the monitor with no
extra space between them. If you are using a larger monitor, it will be
necessary to move the monitor back while keeping the eye tracker at its
optimal distance from the participant, so as to increase the distance
between the participant and the screen while still ensuring that the eye
tracker can track the participants properly (the maximum viewing angle of
the display should be within 32° horizontally and 25° vertically). In such
cases, measure the shortest distance (in millimeters) from the back of the
