Techniques for Multiple Room Connection in Virtual Reality: Walking Within Small Physical Spaces

This IEEE conference talk explores three room-connection techniques for virtual reality—portals, corridors, and central hubs—that create "impossible spaces" through overlapping areas to maximize limited physical space. Learn how these methods enable natural walking in constrained environments based on a study with 33 participants in a 2.5 x 2.5 m area. Discover how each technique positively impacts presence, reduces cybersickness, and enhances spatial awareness while offering unique benefits: portals provide flexibility, corridors create seamless transitions, and central hubs simplify navigation. The presentation demonstrates practical applications for adapting virtual environments to small physical spaces typical in home settings, with potential uses in virtual museum tours, training simulations, and emergency preparedness exercises.
