Swimming teaching system based on virtual reality

Abstract

The invention discloses a swimming teaching system based on virtual reality, which consists of a head-mounted device, a mechanical arm device and a main control device. The head-mounted device comprises VR glasses, a head cover fixed with the top of the VR glasses, an earphone fixed with the back of the VR glasses and a face mask movably fixed on the earphone through a knob. An airflow sensor usedfor detecting the respiration rate of a user is arranged on the inner side of the face mask. The mechanical arm device comprises a bottom support assembly, a waist support assembly fixed on the bottom support assembly and a joint mechanical arm assembly fixedly connected with the waist support assembly. A sensor assembly and a motor are installed in the joint mechanical arm assembly. The main control device judges whether the swimming posture of the user is correct or not through processing the data detected by the sensor assembly, and controls the motor to change the activity resistance of the mechanical arm device for simulating the resistance of the swimming state. The swimming teaching system can provide an immersive interactive swimming learning experience for users.

Description

technical field [0001] The invention belongs to the technical field of sports equipment and virtual reality, and in particular relates to a swimming teaching system based on virtual reality. Background technique [0002] Swimming is a complex sport that requires a high degree of coordination of the body. When people learn to swim, they often repeat the movements of their arms and legs to form muscle memory, so as to achieve accurate body coordination. But learning to swim is extremely inconvenient for most people due to the lack of swimming facilities like swimming instructors and swimming pools. [0003] The patent specification with publication number US4830363A discloses a portable adjustable device for dryland swimming training. The apparatus includes a frame supporting a table on which the user's torso can be supported in a generally horizontal position, a lever device secured to the frame behind the table to supportably receive the user's legs, the lever device being ...

Problems solved by technology

[0005] However, these current swimming teaching systems are only mechanically allowing people to perform repetitive body movements, making users feel that they are just exercising, not learning to swim. The learning process is very boring and cannot be fully immersed in the learning atmosphere.
