10. Positioning the Participant
Before running a calibration, the operator needs to assist the participant
to find a sitting position that is comfortable and yet allows the participant
to be tracked by the
RED250mob ile Eye Tracker . iViewRED helps the
operator to find that position through the use of an Eye Tracking Monitor
.
10.1 Optimal Participant Position
Here are some recommendations for locating the optimal participant
position:
Ensure the participant is sitting comfortably.
Ensure the participant is sitting approximately centered in front of the
RED250mob ile Eye Tracker and directly facing the screen. This
location can be found using the Eye Tracking Monitor .
Ensure the participant is positioned at a distance away from the
screen that is roughly in the center of the operating distance of the
RED250mob ile Eye Tracker . This distance can be found using the
Eye Tracking Monitor .
