Immersive technologies have the potential to transform entertainment, communication and collaboration over distance, training for physical and cognitive tasks, and how people visualize, understand, and make decisions based on an ever growing landscape of complex data. However, despite rapid advances over the past several years and no small amount of media hype, there are numerous theoretical and practical problems yet to be solved before virtual and mixed reality can catch up with our imaginations and make good on these promises. To address fundamental human-computer interaction challenges for immersive systems, the Illusioneering Lab explores novel user interface concepts utilizing an approach of rapid prototyping and experimentation combined with rigorous empirical studies of human perception and spatial cognition.
