Description
Technical Field
[0001] This utility model relates to the field of VR equipment technology, and in particular to an engineering safety experience device based on VR technology. Background Technology
[0002] With the development of VR technology, its related technologies have gradually matured and can be adapted for use in various teaching simulations. In construction safety education, since most construction workers are not fully aware of the importance of safety protection, most safety accidents are caused by momentary negligence on their part. Therefore, using VR devices to experience corresponding safety accidents can effectively alert construction workers and further improve the effectiveness of safety training. However, currently available equipment often simulates safety accidents through videos and modeling, lacking tactile simulation, resulting in poor overall simulation effects and failing to meet the needs of safety simulation training. Utility Model Content
