There was a thoery about the origins of virtual reality, which originated in a paper titled “The Ultimate Display” by American Ivan Sutherland at the IFIP conference in 1965. The paper proposes that people regard the display as a “window to watch the virtual world”, thus creating a precedent for the research of virtual reality technology. The latest technological achievements are the first to be applied in the aerospace and military fields. Today, this paper will share the use of virtual reality in aerospace. application in the field.
How can virtual reality help with training? For personal training, first of all, the astronaut trainer uses the virtual training system to train the astronauts’ weightlessness psychology, so that they can establish a sense of spatial orientation in a weightless environment. Secondly, by building a virtual cockpit model of the spacecraft, astronauts are trained to be familiar with the cabin layout, interface and positional relationship, and to practice flight procedures and operational skills. With a virtual reality kit and simulation manager, astronauts can open hatches, operate switches with their hands, and more. Third, it also has the function of speech recognition and synthesis, which can make the sound of the corresponding action, so that the astronauts can be more immersed in the virtual world and improve the effect of the simulation experiment.
In terms of equipment maintenance, when some key equipment fails during the spacecraft’s on-orbit operation, in order to enable astronauts to perform on-orbit maintenance correctly, maintenance can be performed on the ground or on the space station through virtual reality technology. For example, the Johnson Space Center in the United States has launched a virtual reality system to train astronauts to familiarize themselves with the space environment and prepare for the maintenance of the Hubble telescope. In this way, astronauts have greatly improved their operational level by operating virtual equipment.
In addition, as a supplement or alternative to traditional flight training simulators, virtual trainers can train the crew’s operational skills, cooperative operations among crew members, and even include maintenance training, extravehicular activities, and rendezvous and docking training. Utilize virtual reality technology because the training is not only low-cost, risk-free, but also allows repeated training to improve skill levels.
