Sam’s Virtual Reality research has been operationalised in many fields including medicine, defence, sport, and aviation. In his talk Sam will discuss ways in which we test and evaluate VR tools, and how we make good decisions about when is the right and wrong time to use VR. His talk will tackle important questions such as ‘How do we scientifically and robustly test Virtual Reality for training?’, ‘What new factors come in to play when evaluating VR for patient care?’ His talk will discuss methods and approaches used in a range of previous projects. These methods include bespoke psychometric tests, eye tracking technology, and behavioural assessment, and will be brought to life through examples from his own research projects.
