Embodiment

[0122] Training scene: First aid drill for obstetric eclampsia

[0123] Participants in the training are divided into 4 roles:

[0124] Role A: Attending Obstetrician - Senior Senior;

[0125] Role B: Auxiliary Obstetrician - Junior;

[0126] Role C: Midwife;

[0127] Role D: Anesthesiologist.

[0128] After the system application is started, all four users select "obstetric eclampsia first aid drill" on their own UI interface, and then select their respective roles, and the system automatically loads the virtual scene.

[0129] The virtual scene is an obstetric emergency room, and the virtual objects include pregnant women (already lying on the operating bed), electrocardiogram, fetal heart rate instrument, infusion stand, and item table. There are infusion kits, stethoscopes, injection syringes, blood-drawing syringes, micropumps, eye masks, opening forceps and other items on the item table.

[0130] The standard scenario is as follows:

[0131] 1. All roles display pa...

Abstract

The invention discloses a multi-person cooperative interaction and perception method in a medical virtual reality training scene, and belongs to the field of interaction and perception. The method comprises the steps of constructing a multi-person collaborative virtual environment composed of a plurality of clients and a server; when the operation of a certain client causes the change of the spacecoordinates and direction of an object, the client side generates a Socket sub-process; data format information is sent to a server frame by frame, after a daemon process of the server receives the information, the data is sent to other clients in a UDP broadcasting mode; after the other clients receive the data, the latest spatial position or state change of the object is synchronously updated frame by frame, and the collaborative perception function of all the clients is achieved. According to the method, multiple users with different medical roles are supported to cooperatively operate andperceive in the same virtual operation scene at the same time, so that when any user operates the virtual object, the state and continuity change of the virtual object can be synchronized to other users in real time, and then mutual perception among the multiple users is realized. The method is suitable for the field of medical virtual reality training.

Description

technical field [0001] The invention belongs to the field of interaction and perception in virtual reality training, and in particular relates to a method for realizing collaborative interaction and perception of multiple people in a medical virtual reality training scene. Background technique [0002] Virtual reality technology (English name: Virtual Reality, abbreviated as VR) is a new practical technology developed in the 20th century. Virtual reality technology includes computer, electronic information, and simulation technology in one, and its basic implementation method is to simulate the virtual environment by computer so as to give people a sense of environmental immersion. [0003] With the continuous development of social productivity and science and technology, the demand for VR technology in all walks of life is increasingly strong. VR technology has also made great progress and has gradually become a new field of science and technology. [0004] At present, th...
