Abstract: Methods and apparatus provide for: generating virtual space images by specifying from among a plurality of viewpoint positions and a plurality of directions of line of sight in the virtual space; and displaying the virtual space images on a head-mounted display, where the generating includes changing from a currently selected viewpoint position among the plurality of viewpoint positions to a newly selected viewpoint position among the plurality of viewpoint positions, which is selected in accordance with operation by a user, when generating the virtual space images in response to changing to the newly selected viewpoint position, the generating includes specifying, as a new direction of line of sight among the plurality of directions of line of sight, a direction in which a first position in the virtual space is seen from the newly selected viewpoint position, and at least some of the plurality of viewpoint positions are separated from each other.

Abstract: A display control apparatus includes a display control section that generates a virtual space image by specifying a viewpoint position and a direction of line of sight and displays the image on a head-mounted display. The display control section can specify a plurality of positions in the virtual space as viewpoint positions and can change the viewpoint position to a position determined from among the plurality of positions in accordance with an attitude of the head-mounted display, and when the viewpoint position is changed, the display control section specifies, as a direction of line of sight, the direction in which a first position in the virtual space is seen from the changed viewpoint position.

Abstract: In an information processing device, a photographed image acquiring unit acquires an image which has been photographed by a camera attached to a head mount display. A region determining unit predicts a region which a user gazes at in a display image. An image analyzing unit has a first fineness processing unit and a second fineness processing unit, with the former analyzing a region corresponding to the gaze region in the photographed image with a higher fineness than the latter. An information processing unit performs information processing by using the result of analysis. An image generating unit has a first fineness processing unit and a second fineness processing unit, with the former generating a display image on the gaze region with a higher fineness than the latter. An output unit sends data of the display image to the head mount display.

Abstract: An operation object includes a polyhedron. The polyhedron includes characteristic surfaces formed by cutting each vertex of a cube at different angles. An information processing apparatus acquires a normal vector of each surface from a polarized image thereof. Further, the information processing apparatus identifies the characteristic surface by defining, as a characteristic amount, an angle formed by an average vector Na of normal vectors N1, N2, and N3 of reference surfaces that orthogonally intersect each other and a normal vector N0 of the characteristic surface surrounded by the reference surfaces. The specification result and the normal vectors thereof are used to acquire the position and orientation of the operation object.

Abstract: A distance-measuring device includes first and second stereoscopic cameras each to be used to measure the distance to an object included in an imaging range. The first stereoscopic camera includes two imaging elements arranged side by side in a first direction, and the second stereoscopic camera includes two imaging elements arranged side by side in a second direction. The second direction is defined as a direction which intersects a plane containing the first direction and an imaging direction of the first stereoscopic camera.
