1. A visual and tactile AR medium for providing a user with visual and tactile information matched with augmented reality when the user experiences the augmented reality through the AR medium capable of being connected to a part of a body of the user, the AR medium comprising:
a tactile augmentation member configured to enable the part of the body of the user to feel the augmented reality in a tactile manner;
a visual augmentation member configured to overlay a graphic on the AR medium, and being capable of performing visual change; and
a control member configured to perform transmission and reception with the AR medium,
wherein the control member is configured to control output of the tactile augmentation member or the visual augmentation member, corresponding to input from the user or the AR medium or both,
wherein the visual and tactile AR medium is configured to change an actual length of the visual and tactile AR medium, and has a length extension member that is capable of extending the actual length of the visual and tactile AR medium,
wherein the length extension member comprises:
a fixed module coupled to one end of the visual and tactile AR medium; and
an extension module provided to be partially or entirely overlapped by the fixed module therein, the extension module moving protruding to another end of the visual and tactile AR medium, and
wherein the extension module has a receiving space for a mass object to move therein and the mass object moves along the receiving space to change a center of gravity,
wherein the mass object is configured to be moved along the receiving space of the extension module in a direction in which the actual length of the visual and tactile AR medium is extended after the actual length of the visual and tactile AR medium is extended by the extension module, and
wherein the center-of-gravity movement member further comprises a plurality of catching parts configured for restraint to limit a distance of movement of the mass object when the mass object moves in a direction along an inside of the extension module.
