The University of Toronto conducted a study on the effects of using virtual and augmented reality (VR and AR) on human perception and interaction with the real world. The findings of the study, published in Scientific Reports, revealed that participants exhibited altered movement patterns and errors in real-world tasks after using VR and AR technologies. The study aimed to explore how the adaptation to digital environments affects physical performance once individuals return to reality.
Effects of VR and AR on Movement
The researchers discovered that individuals who used VR tended to undershoot targets, while those who used AR tended to overshot targets. These errors in movement were immediately noticeable after using VR or AR but gradually disappeared as participants readjusted to real-world conditions. This phenomenon raises concerns about the transferability of skills learned in virtual environments to real-world tasks.
Differences Between VR and AR
One surprising finding was that movement patterns in VR and AR had an impact on real-world movements. Additionally, the effects of AR wore off more quickly compared to VR, with participants adjusting faster to real-world conditions after using AR. The researchers suggest that the ability to see and interact with the actual surroundings in AR may help individuals maintain a more accurate sense of depth and distance.
The implications of these findings are significant for industries and training programs that utilize VR and AR technologies for skill development. Understanding the limitations and effects of VR and AR is crucial for ensuring that these technologies are used effectively and safely in professions such as surgery, aviation, and everyday tasks like driving. The study emphasizes the importance of considering how these technologies may impact real-world performance.
The researchers plan to further investigate how different types of VR and AR experiences, including complex and immersive scenarios, affect real-world performance. They are also interested in exploring how training duration and individual differences, such as prior experience with these technologies, influence adaptation and readjustment. This research aims to inform the design of VR and AR systems that minimize negative after-effects and enhance their potential for training and skill development.
The study conducted at the University of Toronto sheds light on the impact of VR and AR on real-world movement and performance. The findings provide valuable insights into how these technologies can influence human behavior and interaction with the physical world. By understanding the challenges and benefits of using VR and AR, industries and training programs can optimize the effectiveness and safety of incorporating these technologies into skill development practices.
