How would you feel standing in a cramped room surrounded by garbage, newspapers, and random camping equipment? Turns out, even when this mess is simulated in virtual reality, it's pretty stressful. I know this because I recently participated in a VR study of hoarders, who are using the technology to confront their disorders.

Researchers out of Ryerson University in Toronto are conducting a study to test the different factors that relate to hoarding, putting test subjects through a series of virtual reality experiments in which they confront hoards of stuff while the researchers measure their stress response. They're finding that even self-identified hoarders don't like being around too much clutter.
