Abstract: To allow users to communicate with each other using the tactile sense, which is not limited to the direction and magnitude of force. A guide rope is constituted by a first gripping component, a first connection component, a second gripping component, and a second connection component that are annularly connected in sequence. An inner portion of the first gripping component, an inner portion of the first connection component, an inner portion of the second gripping component, and an inner portion of the second connection component are all hollow, and the inner portions of the components are connected to form one sealed space. The first gripping component and the second gripping component are formed in such a way as to be easily deformed by a change in pressure of air in the inner portion or a change in force from outside.

Abstract: A vibration measurement presentation plate (160) is a substantially transparent plate and is disposed on a use position side of a user. A display (130) is disposed outside of an imaging range of the camera on a side opposite to the use position side with respect to the plate such that the plate side serves as a display surface. A camera (120) is disposed on the opposite side with respect to the plate and is outside of the viewing range of the display surface of the display via the plate from the use position side so that the plate side is in the imaging range. A vibration measurement sensor (140) and a vibrator (150) are attached to the plate to be out of the imaging range of the camera and out of the viewing range of the display surface of the display via the plate from the use position side.
