Instructions For Using ATW Test

Camera Flash

ATW Test uses the mobile phone flash to illuminate the participant’s eyes. As a result, this improves testing conditions.

iPhone:

The flash intensity adjusts depending on camera quality. Lower-quality cameras need less bright flash. However, they require the phone to be positioned closer to the face. A Higher-quality camera uses a brighter flash. This allows the phone to be positioned farther from the face.

Android: 

You need to keep the flash brightness always remains at 100%. If you are concerned, place strips of semi-transparent tape over the flash. DO NOT DISABLE FLASH or the test accuracy will decrease.

Data Collection Guidelines

For best results, please follow these guidelines:

Room:

Take the test in a quiet room with overhead lighting. Also make sure you and the subject are free of distractions. You should also eliminate sources of direct light from windows,lamps, computers, TVs, or LED screens. These create reflections in the eyes that reduce data quality and test accuracy.

Phone position:

When prompted during the test, position the phone as shown below (see image above). You also need to position the phone so main screen is facing away and back camera is at the bottom.

Slightly tilt the top of flipped phone away from the subject’s face so the bottom of the camera is angled up towards the eyes 

Keep the bottom camera level with the mouth

To avoid too much data loss, please adhere to the these steps.

Hold the back of the flipped phone 2” above the subject.

Blink normally but avoid blinking right when responding to
questions

Avoid movement by keep eyes alert and open, no squinting – keep posture upright with chin down and face forward
