Using Augmented Reality to Improve Driver Attention and Awareness
As autonomous cars become more prevalent, the question of whether drivers can quickly regain control in critical situations arises. Researchers at the University of Glasgow have been exploring the potential of augmented reality to address this concern. The issue lies in the transition from being an active driver to a passive passenger while the car takes control. This shift can lead to decreased awareness and delayed reactions.
The research team identified two challenges that arise when drivers are engaged in other tasks: sustained supervisory tasks and the “look but fail to see” phenomenon. Sustained supervisory tasks refer to the difficulty of maintaining focus and attention on the road while performing another task. The “look but fail to see” phenomenon occurs when drivers fail to process something directly in front of them.
To test whether augmented reality can help address these challenges, the team conducted a laboratory experiment using a steering wheel with screens simulating a windshield view. Participants wore augmented reality headsets and performed either a simple game or a typing task on a tablet while video clips played on the screens. The videos were paused right before potential hazards to assess situational awareness.
The results showed that participants performed worse when multitasking compared to solely focusing on driving. However, when visual cues were added to the augmented reality headset just before the video paused, participants showed better awareness and performed better in the heads-up situation compared to looking down at the tablet.
This suggests that there is a zone in which drivers can engage in other tasks while still staying aware of developing road conditions. Augmented reality cues can help grab drivers’ attention and facilitate a quick switch back to driving in emergency situations.
The findings of this study highlight the importance of further investigating the effects of augmented reality on driver hazard prediction. If autonomous cars are to become commonplace, it is crucial to understand how drivers can effectively transition from being passive passengers to actively controlling the vehicle. Augmented reality could play a significant role in facilitating this transition and improving driver attention and awareness.
In conclusion, as autonomous driving technology advances, researchers are exploring innovative solutions to ensure a smooth transition between autonomous and manual driving modes. Augmented reality shows promise in helping drivers quickly regain control and stay aware of road conditions, even while engaged in other tasks. Continued research in this area will be essential in realizing the full potential of autonomous vehicles and ensuring driver safety.
