In the last few years, immersive virtual reality (iVR) has become a significant part of the entertainment industry. In parallel, there has been a significant uptake in iVR for training in the context of sports, medicine, and dangerous industries. This technology also has potential value for research into human behaviour, allowing for the strict control of sensory inputs in ecologically-valid tasks. In this talk, I will give an overview of some of our recent research in the context of perception and action, highlighting how iVR can be used to study human motor control, and discussing the potential pitfalls of this approach.
