Microsoft researchers have designed virtual reality (VR) solutions to allow users to remain fully immersed in virtual environments, even when walking in real-life locations.
Microsoft's DreamWalker involves advance planning of a real-world path through an outdoor environment and corresponding virtual setting based on geolocation data, with updates on the fly as necessary.
Potential obstacles users encounter are recorded by real-time sensors in the VR equipment, including a dual-band global positioning system sensor, red-green-blue depth cameras, and a Windows Mixed Reality-provided relative position trace. Such impediments may be replaced by virtual counterparts, while arrows guide users in safe directions.
DreamWalker also employs Microsoft's Mise-Unseen eye-tracking technology, so VR surroundings can be revised while the user is looking at something else.
