Researchers at Tokyo Metropolitan University have designed a remote virtual reality (VR) collaboration system that lets users on Segways share not only what they see, but what they see. but also feel the acceleration while moving Riders equipped with cameras and accelerometers were able to express feelings to remote users on a modified wheelchair wearing a VR headset. User surveys showed a significant reduction in VR morbidity, suggesting that Get a better experience for remote collaboration activities.
Virtual Reality (VR) technology is advancing rapidly. Let users experience and share realistic 3D environments. in the field of remote work One of the major advances it offers is the opportunity for employees in different locations. will share what they see and hear in real time. Examples are personal mobile device users in large warehouses, factories, and construction sites. Drivers can easily cover large areas while highlighting problems in real time to distant colleagues. However, one major drawback can ruin the entire experience: VR disease. VR Sickness is a type of motion sickness that comes from the user who sees it. “Move” through the headset without moving at all. Symptoms include headache, nausea, and sometimes vomiting. The example above is a very serious problem. When the sharer of the experience is moving
to fix this problem Researchers from Tokyo Metropolitan University led by Assistant Professor Wibol Yem have created a system that allows users to share not only what they see but also what they see. but also the feeling of movement They focus on Segways, a widely used personal vehicle, equipped with two 3D cameras and an accelerometer kit to measure not only but only visual cues But it also provides detailed information about the car’s acceleration. This was fed back over the Internet to remote users wearing VR headsets on a modified wheelchair with separate motors attached to the wheels. As users on Segway accelerate, so do carts. This allows remote users to not only see the same scenery. But it also feels the same acceleration. Of course, wheelchairs are not allowed to travel the same distance as a segway, it gradually returns to its original position when the segway is not accelerating.
The team put their devices to the test, asking volunteers to be remote users and to rate their experiences. VR sickness decreased by 54% with increased sense of movement. with great ratings for user experience They also noticed subtleties in the feedback method. For example, users found it best when about 60% of the acceleration suggested by the visual signal was fed back to the wheel. This is mainly due to the sensitivity of the vestibular system. (how we sense balance, orientation, and movement) compared to our vision.
Although still in need of improvement But the team system guarantees new possibilities. Exciting for remote collaboration It frees remote users from a major drawback of VR technology.
