The support is adjustable in height according to the body shape of the user. It can be operated even when the user sits or bends by using several hinges. Also, it is composed of a hook ring hinge so that the user can easily enter.

The operation simulation control unit is connected to the left / right and front / rear optical sensors to collect the operation state of the user, and transmits the collected information to the computer to transmit the operation contents of the user to the HMD screen in real time.

The gait simulation apparatus according to the present invention has the following effects.

First, physical action (walking, running, turning, etc.) can be practically performed on the present invention to increase the fun and movement feeling, and the user's behavior (physical motion contents) Immersive).

Secondly, it is possible to increase the efficiency of games, training, and exercise because the cost of manufacturing the apparatus is low, and the user can perform various realistic actions in a narrow space.

Third, the gait simulator can be used independently or in combination with several gait simulators, so that the gait simulator can be applied to groups, roles, and so on.

The effects of the present invention are not limited to those mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the following description.
