How Disney Thinks About Virtual Reality For Its Theme Parks
Yang says that one major advantage to the cave approach is that it cuts down on the number of factors that can lead to motion sickness while you’re in the virtual reality experience. Instead of implementing stereoscopic 3D effects, Disney is able to use motion tracking to draw 2D images that look like they have depth — like the Amazon Fire Phone’s “dynamic perspective,” but at a much larger scale.
...Through years of testing these experiences, the team learned tricks for further reducing motion sickness, like not allowing the ride and screen to simulate the zero-point turns common in first-person shooters (and therefore, most early VR experiences) because most humans aren’t actually comfortable with constantly looking left and right without accommodating the change with a slight movement of the rest of their body.
...in the Q/A session after the main keynote, Yang said that the team is working on a more generalized version of this advanced cave system that could be used for multiple experiences and walk-through attractions.
