Abstract

The invention provides a smoke interaction method in an evacuation environment based on virtual reality, comprising the following steps: connecting hardware equipment, automatic control equipment anda VR scene software system, and establishing a model; and according to the distance, displayed by the VR scene software system, between the user and the smoke particle system, controlling the automatic control equipment to output the output heat of the smoke so as to realize the interactive operation of the smoke in the evacuation environment based on virtual reality. According to the method, a smell player is connected to a virtual subway station fire experiment scene; the method can be used for HTC VIVE and KAT running machines, automatic control over smoke in a virtual scene in a real physical environment is achieved, man-machine interaction based on an olfactory channel is provided, the method can be used for carrying out a fire evacuation behavior experiment and collecting behavior experiment data, and perception authenticity and real-time performance are achieved. The invention further provides a smoke interaction device in the evacuation environment based on virtual reality.

Description

technical field [0001] The present disclosure relates to the technical field of virtual reality and scene simulation, in particular, to a virtual reality-based smoke interaction method and device in an evacuation environment. Background technique [0002] Common smoke-providing devices in life include stage fog machines and 4D cinema special effects systems. The smog technology developed based on VR includes scent players, and the specific models include VAQSO VR equipment and Smell Kingdom VR scent players. In the prior art, the transformation process of the stage fog machine is cumbersome, and the stability of the system cannot be guaranteed. The market cost of 4D cinema special effects system is relatively high, and the experience is poor. VAQSO VR, with a battery life of 2 hours, the price is unknown, it needs to be purchased abroad, and the availability is unknown. That is, the scope of application is limited and does not have wide applicability. Contents of the in...
