There are several environmental factors that can affect the accuracy of the test. Please make sure the testing room is properly prepared prior to giving a test.
These suggestions come from the Converus science team.
- Room should be dimly lit. Bright lights can affect pupil dilation measurements and/or cause reflections on the screen that can affect the results. Please note that the room should not be completely dark, as this may affect the examinee’s ability to see the keyboard or accurately respond to test questions.
- Do not use overhead fluorescent lights. Overhead fluorescent lights affect the accuracy of the eye tracker.
- Do use indirect lighting. Lights should not shine directly on the examinee or EyeDetect station.
- Windows should be covered. Dark curtains or dark paper should cover any windows in the room.
- Desk and workstation are positioned correctly. No lights or windows should be behind the examinee.
