Does VR improve or impair concentration?
It can do both. Whether virtual reality (VR) improves or impairs concentration depends on how it is used and how each user responds. A well-designed application can significantly increase attention, while long sessions lead to fatigue.
1. Improved concentration
In many cases, VR can improve concentration because it creates an immersive environment that shields users from outside distractions. In training sessions and simulations in particular, users can become deeply absorbed in their tasks, which helps them focus on the content. This is because VR controls what users see and hear and directs all their attention to the virtual experience. In a PwC study (2020), employees in VR training said they were up to four times more focused than in e-learning.
2. Possible challenges
On the other hand, using VR for longer periods can cause fatigue that reduces concentration. This happens mainly to people with little VR experience who still have to get used to the controls, which alone can demand a fair amount of attention. There is a familiarization effect, however: once people have used a VR headset for a while, operating it becomes second nature and no longer distracts them.
Some users report VR sickness or headaches when they use VR for an extended period, which can affect their ability to concentrate. Here, too, familiarization usually helps, so these symptoms appear later or not at all. A review of 39 studies confirms this effect (Dużmańska et al. 2018). Content is a decisive factor: simulations with very few fast visual stimuli are easier to tolerate than applications with a lot of movement.
3. Our experience
A well-designed VR application can significantly increase the attention of people new to VR for up to 20 minutes. If the app is intuitive and has no learning curve, the technology doesn’t distract but keeps the focus on what matters. We also observe, though, that people new to VR show clear signs of fatigue after 20 to 30 minutes. At that point, the simulation should end or at least pause for a 10- to 15-minute break. Experienced VR headset users can stay attentive for one to two hours, although we recommend regular breaks for them as well.
Conclusion
VR can improve concentration by providing an immersive, distraction-free environment. Use should be carefully measured, however, to avoid overload and fatigue. The VR application has to be designed to support focus. Regular breaks are the key to staying focused over time.
