VR devices collect human motion signals and feed them into a series of virtual scenes, providing users with an interactive and immersive experience. Suspended VR omnidirectional mobile platforms can simulate human movements such as walking, running, and jumping, enabling a variety of applications in various scenarios. For example, in the gaming field, it can simulate actions in parkour and shooting games; in the medical field, it can collect user motion signals for behavioral experiments, simulate thrilling scenarios, and test users' stress responses; in the firefighting field, it can simulate real disaster scenarios to train firefighters' ability to deal with disasters, or train the general public's ability to escape from disasters.
