If you’ve tried out any of the new virtual-reality devices, you’ll know that they can be incredibly convincing—but they can also cause you to lose touch with your lunch. Now a new trick adjusts the user’s field of view on the fly to help alleviate the issue.
Motion sickness can occur when the body receives mixed messages about movement: the eyes may see one thing, while the fluid swilling around within the inner ear might tell another story. When the two don’t marry up, people feel uncomfortable, disoriented, and sometimes nauseated. So a Columbia University team decided to focus on what could be done to change the visual cues a user sees when a VR environment doesn't tally with the real-world situation.
