Microsoft researchers have created a system redirection virtual reality in the scale of the city

In the adaptation by Steven Spielberg in 2018 for the novel by Ernest Kline “the First player to get ready” 2011 network simulation places known as OASIS, is a difficult battle for control of the fictional multiverse.


In the film, fans of The OASIS move on to the physical streets decorated with virtual appliances, while their system seamlessly displays the virtual world into their physical environment — thus maintaining the illusion. Of course, it looks quite socially awkward and raises uncomfortable questions about the value that people attach to their physical environment, but it still represented a technical achievement if it really is possible to implement:



However, even a simple townsfolk who are familiar with virtual reality technology, you can look at these images and wonder whether it is ever possible like. For example, it is unclear how the virtual world can be arranged to provide navigation when walking in public places outdoors.


It turns out that Microsoft researchers are already responding to these responses. The publication of a new article presented at the Symposium of the ACM software and UI technology ( UIST ) under the title ” DreamWalker “, prepared by a graduate student at Stanford University Jackie young , who at the time was an Intern at Microsoft Research, and Microsoft researchers Eyal Ofcom, Andy Wilsonii and Christian Holz. The document describes in detail about how they built a system of diverting the pedestrian scale of the city to a virtual reality headset with the Samsung Odyssey and additional sensory equipment.





The full title of the article: “DreamWalker: replace the experience of walking in the real world virtual reality”, and you can read the entire 14-page PDF on their own.


In the end, however, “we explore a future where people spend much more time in virtual reality, even in moments when they are between locations in the real world”. DreamWalker is based on earlier studies, working “in an unprecedented large-scale, uncontrolled and public areas on adjacent tracks in the real world, where there are moving vehicles.”


According to the article:


“Windows Mixed Reality provides tracking inside-out on the Samsung VR headset Odyssey, updating perceive 6D location with a frequency of 90 Hz. Experimentally we measured 1 m drift within only 30 m only through tracking inside-out. Dual camera Intel RealSense 425 provide an RGB image, slightly tilted and rotated 90 degrees to achieve a large field of view (86◦ × 98◦). We have created a special adapter for computer-backpack that converts Thunderbolt 3 four USB 3 ports, and thus supports the bandwidth needed to stream both cameras RGB with a resolution of 640 × 480 (depth) and 640 (RGB) × 480 at a frequency of 30 Hz. Finally, the GPS data received from the sensor inside the phone Xiaomi Mi 8… “


The paper describes how measurements of all of these devices are combined and analyzed to keep a person in virtual reality for a safe and comfortable way in the real world without removing the headphones, so that “8 of the participants have passed through the campus on a 15-minute route, experiencing a virtual Manhattan, which was full of animated people, cars and other objects.”


In the video below you can see the different ways in which software encourages people to stay on the right path, including the use of “humanoid” animated virtual characters who “move to the location of the detected obstacles and direct the user to the destination”.



In conclusion, the article States that “each member confidently walked for 15 minutes in a DreamWalker that has demonstrated the potential of our system in order to make the repetitive tasks of walking in the real world more interesting.”
