Visual Edge is our Useful Field of View (UFOV) exercise. Training on the Visual Edge task has been shown in published scientific studies to reduce at fault accident risk by 50%, over a 5 year period, for older drivers.
Two vehicles are shown.
One of two vehicles is displayed in the road ahead of you for a short period of time.
- On more difficult levels, you will also see a diamond-shaped road hazard sign in your peripheral vision.
- On even more difficult levels, you will also see circular distractor signs.
Visual noise, black and white static, is displayed for a short period of time to clear the retina of visual artifacts.
You are shown the two vehicles on the road and asked what vehicle was displayed during step 2.
- You must pick a vehicle to continue. If the vehicle flashed by too fast during step 2, we ask you to guess. Follow your instincts, often you know the correct answer even if you are not confident.
- If you click on the wrong vehicle the trial will end you will skip to step 6.
If you choose the correct vehicle and you are on a level with a peripheral hazard sign, you will be asked to click on the section of the screen the peripheral hazard sign appeared in.
If you have responded correctly, the car you are in will appear to zoom along and the next trial will have a shorter display time on step 2, making the task harder. If you respond incorrectly, the car will appear to brake and the next trial will have a longer display time on step 2, making the task easier.

The adaptive algorithm used in this exercise is intended to find a display time for step 2 where you are able to respond correctly 80% of the time, thus keeping the exercise a challenge. As a result, you will find that about 20% of the time, you are unsure about how which answer is correct. This is what makes the exercise a challenge.
