Abstract: In a display apparatus, an acquisition unit acquires coordinate information associated with a fiducial marker installed in a specific area of a real space and a virtual object including advertisement information, an imaging unit images a real image and the fiducial marker, a self-position specifying unit specifies a self-position from a distance and an angle from the imaged fiducial marker, a state detecting unit detects a distance and an angle of view from the virtual point based on the self-position, a selection unit selects any virtual object existing within an angle of view from the self-position, and a display unit displays a main object of the virtual object existing within the angle of view from the self-position in such a manner that the main object is superimposed on a relative position on the real image and displays a main object and a sub object of the selected virtual object.

Abstract: An object of the present invention is to provide a toothbrush that enables an appropriate brushing pressure to be more reliably recognized. A head portion (10) provided on a tip end side in a long axis direction and having a bristle tufting surface (11), a grip portion (30) disposed on a rear end side from the head portion, and a neck portion (20) disposed between the bristle tufting surface and the grip portion are provided. A sound generation portion (70) that generates a click sound due to deformation when an external force in a first direction orthogonal to the bristle tufting surface exceeds a threshold value is provided on a rear end side from the bristle tufting surface.
