Background With the popularization of Virtual Reality (VR) technology, the application of the VR technology in the fields of education, training, rehabilitation training, entertainment and the like is increasingly deep, and the scene that a user wears VR equipment to perform long-time immersive experience is more common. However, in scenes such as amblyopia rehabilitation training of children, remote learning, etc. where the user is required to remain relatively stationary and in a standard sitting position, the user often unknowingly suffers from problems such as leaning forward, head-skewed, sitting too high or too low due to lack of effective real-time posture feedback. The bad sitting postures can not only cause fatigue damage of the neck and the spine, affect the comfort and health of long-term use, but also directly affect the accuracy of a training light path and visual stimulation in the special training such as vision rehabilitation, thereby seriously weakening the training effect.
