A head-mounted device to be worn on a user's head includes a first pressing member to press, for example, an occipital region, a second pressing member to press, for example, a parietal region, and first and second linear members connected to the first and second pressing members respectively. The first and second linear members are guided so that a change in lengths of the first and second linear members causes the first and second pressing members to move in the first and second directions respectively. An adjustment unit to adjust the lengths of the first and second linear members includes first and second wind-up units connected to a rotational operation member and to wind up the first and second linear members respectively.

Head-mounted device

A head-mountable apparatus mountable on a head of an observer comprises a first pressing member which presses a first portion of the head; a second pressing member which presses a second portion of the head; and an adjustment unit adapted to move the first pressing member and the second pressing member to positions where the first pressing member and the second pressing member respectively press the first portion and the second portion.

Head-mountable apparatus

A head-mounted device for mounting on the head of a user includes a first pressing member for pressing a first portion of the head from a first direction; a second pressing member for pressing a second portion of the head from a second direction that is different from the first direction; a string member that concatenates the first pressing member and the second pressing member; a structure that guides the string member so that the first and the second pressing members move in the first and the second directions, respectively, according to changes in the length of the string member; and an adjusting unit that adjusts the length of the string member.

The invention provides a head mounted image-sensing display device including a pair of image-sensing units (R,L) that stereoscopically capture a physical space and output a pair of stereoscopic images, and display units (R,L) for displaying images for the right eye and images for the left eye. Image sensing parameters that are previously measured for the image-sensing units are stored in image sensing parameter storage units (R,L). As a result, a difference in parallax between captured images of a physical space and images of a virtual object is reduced.

Head mounted image-sensing display device and composite image generating apparatus

A head-mounted device mounted on a wearer's head has a first pressing unit to press against the wearer's head from a position of his/her medulla, a second pressing unit to press against the wearer's head in an opposite direction to a pressing direction of the first pressing unit, and a mounting unit to mount the head-mounted device on the wearer's head by adjusting at least one of the first pressing unit and the second pressing unit.

Head-mounted display

To shield a frame area, a frame-like shield memberis superimposed over an LCDwhile being separated from the LCDby a distance L. The distance L satisfies&#x3c;2&#xd7;()&#xd7;where f is a focal length of an optical system, D is a human pupil diameter determined statistically in advance, B is a width of the frame area, and A is a value determined statistically in advance as a width which will not be able to be shielded on a side of the frame area to be shielded by a side of the shield member.

Head-mounted display and head-mounted video display

This specification discloses a mounting mechanism for a display portion onto the head in which the movement range of a wearer is not restricted and it becomes possible to make the display portion follow the head. This mounting mechanism has a head mounting portion for mounting the display portion on the head, a weight supporting portion mounted on any other body portion than the head for supporting part of the weight of the head mounting portion, and a connecting member for connecting the head mounting portion and the weight supporting portion together so that the head mounting portion may be movable following the movement of the head.

Mounting mechanism and head-mounted image display apparatus

A light source device includes at least one dot-like light source, a substrate where the dot-like light source is arranged, and a reflection member which is arrange to be in contact with a light-emitting surface of the dot-like light source and cover the light-emitting surface. The reflection member further includes an opening to pass therethrough a beam emitted from the dot-like light source.

Light source device and display apparatus

A head mounted apparatus mounted on a head of a user includes an apparatus body to be mounted on a front side of the head, a frame for supporting the apparatus body, the frame extending in a longitudinal direction at both sides of the head when the frame is mounted on the head, a front compressing portion provided on the frame or the apparatus body, and compressed against a frontal region of the head, first and second adjusters provided at both sides of the frame so that the first and second adjusters can move in the longitudinal direction relative to the frame, a back member that includes a back compressing portion compressed against an occipital region of the head, and is held by the first and second adjusters, and an interlock mechanism for enabling, as one of the first and second adjusters moves relative to the frame, the other of the first and second adjusters to move with the same moving amount relative to the frame in the same direction as the one.
