In addition, the VR device is composed of a processor, a memory, a receiver, a display, a speaker/microphone, and a wireless communication module. , Terminal cradle, speed calculation unit, direction calculation unit, pedal, and handle.

In addition, in the VR bicycle exercise equipment and contents providing method using mobile,

Downloading, by the mobile device, VR application content from a content providing server;

Recognizing the mobile device by a VR bicycle exercise device through a terminal recognition sensor;

Receiving, by the VR bicycle exercise device, the VR application content data;

Storing the received content data in a memory unit and processing it in real time through a processor;

Transmitting the processed data to a VR device through a wireless communication module; And

And outputting the transmitted data on a display of a VR device.

According to the present invention, a large screen or digital signage is not separately installed in front of the exercise equipment, but a VR device is interlocked with the exercise equipment, so the cost is much reduced.

In addition, since the video is displayed through the display of the VR device, immersion and realism are maximized, and the effect can be maximized without getting bored during exercise.
