Step A) Posion the monitor so that it subtends no more than 32 degrees of visual angle horizontally
and 25 degrees of visual angle vercally for the parcipant. The eye-to-monitor distance should be at
least 1.75 mes the display width to ensure that it falls within the trackable range.
Step B) Posion the parcipant so that the eyes align with the top quarter of the monitor – adjust the
chair and/or head support to ensure this alignment.
Step C) Posion the eye tracker so that the distance from the top knob on the front of the Desktop
Mount to the front of the chinrest is 50-55 cm. If using Remote Mode, make sure that the reported
target distance on the Host PC is around 60 cm (55-60 cm is ideal for calibraon).
Step D) Adjust the height of the eye tracker so that it is as high as possible without blocking the
parcipant’s view of the display.
