VR headsets could enhance screen-based hazard perception training
Using virtual reality (VR) headsets in driver hazard perception is just as good as, and in some conditions better than, single screen tests at differentiating between safe and less-safe drivers, a study has found.
The six-part study was carried out by Nottingham Trent University (NTU), having been commissioned and funded by the RAC Foundation, the Road Safety Trust and the DVSA. Using a ‘what happens next?’ method of hazard identification, psychologists explored how both new and experienced drivers reacted when using a VR headset. The 360-degree view of potential hazards gave participants the opportunity to look all around them, such as into side roads as they pass, or to check side mirrors and blind spots for other road users.
The study involved more than 400 participants, with drivers reporting that the VR experience was more engaging, immersive and realistic than a single monitor test on average. They also preferred real video of roads to a CGI simulation, rating them higher for clarity and visual complexity on average. The research team also analysed the levels of cybersickness among participants, finding levels very low with only 4% of participants removed from studies due to sickness, despite the screen regularly cutting to black between hazards, which can prompt nausea.
David Crundall, lead researcher and professor of psychology at NTU’s School of Social Sciences (and a member of UKROEd’s Research and Development team), said: “VR offers great opportunities for driver assessment and training beyond formal licensing procedures. Using these headsets allows us to diversify the range of hazards presented and can be particularly useful for drivers who need practise at spotting hazards in the most realistic environments without being put in danger, such as the emergency services.
“This is an opportunity to make drivers safer by teaching them the fundamentals of hazard awareness using innovative techniques and methods that go beyond the traditional UK test.”
