The application provides a positioning data smoothing prediction method, device and system for medical rescue, and relates to the technical field of human-computer interaction. The method comprises the following steps: acquiring measurement data of each infrared camera and measurement data of each sensor on a wearable device at a current time; determining the pose of an operator based on the measurement data of each infrared camera and the measurement data of each sensor on the wearable device; predicting the predicted pose of a virtual operator at a next time based on the pose of the operator, the pose of a digitized wounded person, the instrument used by the virtual operator, and the motion trajectory of the operator in a previous period; wherein the virtual operator is the corresponding operator of the operator in a virtual scene, and the previous period is a historical period including the current time; and determining the final display pose of the virtual operator in the virtual scene based on the predicted pose and the real pose of the operator at the next time sent by a server. The application can effectively alleviate the lag caused by network delay.

The application provides a wind tunnel VR simulation method and device for multi-modal collaborative control, relates to the technical field of virtual reality simulation, and comprises the following steps: acquiring multi-source sensor data of an experimenter in a virtual scene, and pre-processing the multi-source sensor data; performing fusion processing on the pre-processed multi-source sensor data, and calculating whole-body posture data of the experimenter; identifying the action intention of the experimenter based on the whole-body posture data, and evaluating the body state category of the experimenter; generating wind tunnel control instructions and VR scene control instructions according to the action intention and the body state category of the experimenter; updating the virtual scene according to the VR scene control instructions, and adjusting the wind speed of the wind tunnel according to the wind tunnel control instructions. The application is used for solving the problem that the existing simulation method lacks intelligent interaction, which seriously affects the immersion of the experimenter and may also cause the experimenter to feel dizzy and uncomfortable.
