The Useful Field of View (UFOV) Assessment is a breakthrough cognitive assessment that reliably predicts crash risk in drivers. It was developed by Dr. Karlene Ball and Dr. Daniel Roenker of Visual Awareness, who were dedicated to improving mobility and quality of life for older adults and people with cognitive concerns. You can learn more about the UFOV development process. Posit Science is the exclusive licensee of the UFOV assessment and training technology.

What Is “Useful Field of View”?

“Useful field of view” is the area from which you can extract information in a single glance without moving your head or eyes.

Studies have shown that the size of useful field of view plays a key role in a person’s ability to drive safely. Individuals who experience reductions in their useful field of view are more likely to be involved in traffic accidents. In fact, individuals with poor useful field of view are more than twice as likely to be involved in a car crash than those in the normal range.1

What is the UFOV Assessment?

The UFOV Assessment is a short (5-10 minute) online test that is typically given to an individual by a healthcare professional. It can be completed on any Internet-connected computer.

The purpose of the UFOV Assessment is to determine the size of the test-taker’s useful field of view, which can also be defined in terms of visual processing speed. Processing speed scores indicating a 40% or greater reduction in useful field of view signal cognitive performance concerns. 40% was chosen as the threshold because it is the point of greatest increase in crash frequency.

The body of research establishing the relationship between the UFOV Assessment and driving safety is impressive. In fact, studies show the UFOV Assessment is a better predictor of automotive crash risk than the tests typically used at the Department of Motor Vehicles.2

Who Should Take the Assessment?

UFOV is intended for people of all ages when testing cognitive function. It’s recommended for individuals who drive for a living, have experienced vehicle crashes, or are at risk for accidents because of age-related decline or health issues.

One of the most important groups to test is senior drivers. Millions of senior drivers are adversely affected by UFOV performance issues, causing them to drive less frequently than they would like, and putting them at risk of a car crash. And every day, healthy older drivers face arbitrary driving restrictions based on common stereotypes of age-related declines in vision and cognition. The UFOV Assessment determines which drivers have cognitive performance that affects driving safety, and which drivers are above the safe threshold.

No matter how an individual scores on the UFOV Assessment, most people can increase their useful field of view and speed up visual processing by using BrainHQ—a brain-training program that includes the UFOV training technology that has been proven to improve driving safety both in clinical trials and in the field.

Bringing the UFOV Assessment to Your Customers or Patients

Health care providers, insurers, and other groups use the UFOV Assessment to assess cognitive ability and predict driving safety in their patients and customers. Doing so can help keep people safe on the road while bringing a competitive edge to your practice or organization—and it’s less expensive, quicker, and easier to administer than simulators or on-the-road evaluations. It’s also non-invasive and confidential. What’s more, if a person’s score indicates a UFOV concern, you can also help them improve their UFOV with the BrainHQ brain training program.
