User-exhibit distance based collaborative interaction method and system for augmented reality museum

A user-exhibit distance based collaborative interaction method for an augmented reality museum, comprising:

• detecting and acquiring dynamic position information of a user, wherein the dynamic position information comprises a physical distance between the user and an exhibit, an orientation towards the exhibit and a moving speed, and calculating a sensing distance of the user in real time according to the physical distance, the orientation towards the exhibit and the moving speed;
• establishing a distance model with the exhibit as a center according to the sensing distance, and setting interaction authority of the user according to the distance model and a real-time sensing distance of the user;
• dynamically matching a single-user interaction mode and a multi-user collaborative interaction mode within the interaction authority of the user to the user according to the interaction authority of the user corresponding to the sensing distance of the user;
• executing, by the user, a single-user interaction behavior and a multi-user collaborative interaction behavior in real time according to the single-user interaction mode and the multi-user collaborative interaction mode;
• and
• realizing recommendation of the exhibit between users according to a real-time single-user interaction behavior result and a real-time multi-user collaborative interaction behavior result;
• wherein a method for acquiring the physical distance between the user and the exhibit, the orientation towards the exhibit and the moving speed comprises:
• identifying, by an augmented reality device, a plane where the exhibit is located, and then calculating a straight-line distance between a camera of the augmented reality device and a center point of the plane to serve as the physical distance between the user and the exhibit when the user views the exhibit;
• calculating an inclination angle of the augmented reality device to serve as the orientation towards the exhibit according to data of a gravity sensor and an angular speed sensor in the augmented reality device;
• and
• calculating, by a gyroscope in the augmented reality device, displacement of the user within 1 second in an orientation towards the exhibit to serve as the moving speed.
