An information processing device includes: a displacement information acquisition unit that acquires displacement information corresponding to 3-dimensional displacement of a predetermined portion of an object that a user mounts in accordance with a body motion on the basis of positional information of the predetermined portion and an output control unit that performs control such that an output unit performs a predetermined output on the basis of the acquired displacement information. The object has, for example, a seatback on which a user can sit. The displacement information acquisition unit acquires a change in a position in at least one of front and rear directions, right and left directions, or upward and downward directions of a seatback.

Information processing device and information processing method

An image display apparatus includes a light source, an image generation unit which generates image light, and a projection optical system including a first lens system which refracts the image light, a first reflection optical system having two or more reflection surfaces that fold back and reflect the refracted image light, a second lens system which refracts the image light reflected by the first reflection optical system, and a second reflection optical system which reflects the image light refracted by the second lens system toward a projection object. The first reflection optical system includes an optical component having a principal surface on which one of the reflection surfaces is configured. The principal surface includes a transmission surface that allows the image light to pass therethrough, configured in a region having a shape rotationally asymmetric to the reflection surface with respect to an optical axis of the optical component.

Image display apparatus and projection optical system

An image display apparatus according to an aspect of the present technology includes a light source, an image generator, and a projection optical system. The image generator modulates light emitted from the light source and generates image light. The projection optical system includes a lens system and a concave reflective surface. The lens system is configured on a basis of a reference axis at a position on which the generated image light is incident, and has a positive refracting power as a whole. The concave reflective surface is configured on a basis of the reference axis, and reflects the image light emitted from the lens system toward a projection target. In addition, the concave reflective surface reflects at least one or more light beams included in the image light incident on the concave reflective surface, toward a direction that intersects with a direction along the reference axis at an angle of 80 degrees or more.
