To be able to start an assessment the student needs to be positioned in front of the external monitor. For the eyetracker to pick up the students eyemovements requirements in distance and height need to be met. See full guide for best practices.
The way the student is placed and positioned in frong of the external monitor is paramount for the assessment to get a good quality recording, here are some things to consider:
Placing the pupil in front of the monitor
Main points:
- Your laptop and the pupil monitor should be at a 90-degree angle to each other.
- The pupil should sit tight against the table with their back straight against the back of their chair.
- The pupil’s arms should be resting on the table.
- The distance between the pupil and the screen should be about 65 centimetres/26 inches. See example picture below
Positioning
Positioning the pupil within the testing application.
Ask the pupil to look at the centre of the screen. Move the pupil monitor so that both the circle and the cross turn green.
- Move the monitor forward or backward to gain the correct distance, which is about 65 cm/26 inches, until both the circles turn green.
- Move the monitor sideways and angle it so that the cross turns green. If no cross is visible, adjust the angle of the monitor so the eye tracker can detect the pupil’s eyes.
- When the circle and cross are green, click "Next" to continue. You will not be able to proceed if the positioning is not good enough.
When the distance between the pupil's eyes and the screen is between 48 and 80 cm (19-31.5 inches), the recording quality is usually good enough. The limits are stricter during the positioning itself than during the recordings. This is to create good conditions for ideal recording quality throughout the test.
