Architects and design researchers have created a virtual reality experiment in which they try to get participants lost. The participants wear a virtual head piece and try to navigate their way through non-descript hallways and unmarked offices. The researchers are using the program to learn what cues we humans pick up on when we’re traveling in an unfamiliar space, like a hospital or government building. They found we picked up on really subtle stuff like patterning in the carpet. They hope this research will help them design easier-to-navigate buildings, or at least design more interesting carpet.
