Last Friday, the "Shenzhou 11" spacecraft ended its 33-day space trip and returned smoothly. Some people may be curious. How long did the two astronauts Jing Haipeng and Chen Dong contact their families in space? In fact, with the first domestic VR glasses that landed in space, they successfully achieved a “reunion†with their families.
In order to alleviate the psychological pressure of astronauts in space, the Chinese Astronaut Research and Training Center decided to adopt a highly immersive VR technology, so the astronauts were specially equipped with "customized version" VR glasses suitable for the space environment.
Commonly used VR glasses generally provide a basic spatial direction reference through a gyroscope to achieve tracking of the human head. However, due to the special nature of the weight loss condition of the space environment, the gyroscope cannot be guaranteed to work normally. Therefore, the "space customization version" VR glasses adopt two tracking modes of optical and gyroscope, and the algorithm ensures that the head posture and the video scene display angle are consistent. Accurate guarantee of motion tracking.
This set of equipment called "Psychic Soothing Components" was jointly developed by the China Astronaut Research and Training Center and Beijing Institute of Technology. Divided into embedded display unit, head-mounted unit, earphone and charging unit, it can generate series of VR scenes related to reality, such as mountains and lakes, “unit family†and “happy familyâ€, and soothing astronauts by playing panoramic video. The tension and anxiety and other emotions; the device will also automatically monitor the head posture and adjust the corresponding scene of the picture.
