Abstract: An information processing device includes a control unit that performs control to output information regarding an image of a user viewpoint in a virtual space, in which the control unit performs control to switch a display corresponding to a performer included in the image between a live-action image generated based on a captured image of the performer and a character image corresponding to the performer, according to a result of detecting a state of at least one user in the virtual space or a state of the virtual space.

Abstract: Proposed is an information processing apparatus including a control unit that controls display of a virtual space, in which the control unit performs control to acquire communication information of one or more other users in another virtual space and present the acquired communication information by a virtual object disposed in the virtual space.

Abstract: Provided is a structure for joining members applicable even to different members. Included are first and second plate-like members 1 and 2 to be joined which are stacked one on the other for face-to-face contact and formed with respective, mutually contiguous holes 3 and 4, a fastening member 5 formed with a threaded hole 20 contiguous with the holes 3 and 4 of the members 1 and 2 and abutting on the member 1 on a side away from the member 2 and an auxiliary member 7 inserted into the holes 20, 3 and 4 of the members 5, 1 and 2. Due to frictional heat and plastic flow, material derived from the member 7 is adapted to enter into a threaded groove on an inner periphery of the hole 20 of the member 5 and cover a circumference of the hole 4 of the member 2 so as to join the members 1 and 2 together.
