However, the same subjects had a difficult time maneuvering backward, starting from the building's exit rather than the entrance. Such a skill can be helpful in emergencies. But they hesitate and have a difficult time determining where they are. The research also shows that consulting a building blueprint in addition to virtual reality training resolves the hesitation and location problems. Professor Clawson, who specializes in human learning and memory, said the next research step is designing glass walls in the computer models.
People get a better idea of the building layout when the model's walls are glass.
