A method for substantially matching a color or pattern of article of clothing or other object so that substantially the same color or pattern can be displayed on a flexible footwear display. The other object may include a user eye, hair or other human body part. The method includes the use of a detector used to determine color or pattern values that match the color or pattern of the clothing or other object. The color or pattern values used to be displayed on the footwear can be determined automatically or by the user. The flexible footwear display may occupy 25% to 100% of the outer surface of the footwear, have a pixel count of 50 to 2,000,000 pixels or a color depth in the range of 8-bits to 48-bits.

A display apparatus includes a frame mounted on an observer's head, an image display device attached to the frame and a dimming device 700, the image display device includes an image forming device and an optical device 120, 320 having a virtual image forming region 140, 340 where a virtual image is formed on the basis of light emitted from the image forming device, the optical device 120, 320 overlaps with a portion of the dimming device 700, at the time of operation of the dimming device 700, a light blocking ratio of the dimming device 700 is changed over a range of from an upper region 701U to a lower region 701D and/or over a range of from an inner region 701C to an outer region 701S, and a virtual image forming region facing region 701 has a light blocking ratio higher than the light blocking ratio of the lower region 701D or the outer region 701S.

A vehicle entertainment system includes a cradle disposed in a headrest of a vehicle and having a slot, and a vehicle entertainment unit including a display and a locking mechanism. Upon placing the vehicle entertainment unit in the cradle, the locking mechanism is inserted into the slot to fixedly lock the vehicle entertainment unit in the cradle. Upon fixedly locking the vehicle entertainment unit in the cradle, a space aligned with the locking mechanism is disposed between a first side of the cradle and a first side of the vehicle entertainment unit. The space is shaped and dimensioned to receive a removal tool that contacts the locking mechanism through the space to disengage the locking mechanism from the slot.

An external scene image captured by an external scene imaging electronic camera attached to a head mounted display (HMD) is projected and displayed onto an image display screen arranged in front of the eyes of the user as a virtual image with a suitable viewing distance corresponding to the visual acuity of the user. At this time, for each object image presented in the virtual image of the external scene image, the virtual image is processed and formatted to add a predetermined degree of binocular disparity and image blur to the virtual image projected and displayed on the right and the left image display screen on the basis of a predetermined converted distance calculated from the real distance of each object. Thus, the user is given a sense of a realistic perspective for the virtual image of the external scene, free of the discomfort or unease.

The object of the present invention is to provide a fragrance presentation device which prevents an unintended smell from being presented. A fragrance presentation device for use with a display device which can be mounted on the head of a user includes a fragrance presentation module disposed in a fragrance presentation position in the vicinity of the nostrils of a person on which the display device is mounted, a fragrance holder having a fragrance container for holding a fragrance therein, the fragrance holder placing the fragrance container in a position spaced from the fragrance presentation position at least while the fragrance is not presented, and delivering the fragrance out of the fragrance container when the fragrance in the fragrance container is presented, and a fragrance conductor for conducting the fragrance which has been delivered out of the fragrance holder to the fragrance presentation module.

A projection optical system for use in an image display apparatus having an illumination optical system applying light from a light source, and an image display device receiving the light from the illumination optical system to form a projection image includes a projector lens composed of plural lenses, a first mirror, and a second mirror formed of a concave mirror. The projection optical system is configured to project the projection image onto a projection surface. A projection luminous flux passing through the projector lens to be incident on the first mirror is a luminous flux exhibiting divergence. The projection luminous flux reflected off the second mirror after having reflected off the first mirror is converged once, and the once converged projection luminous flux is projected onto the projection surface. A lens surface of a lens located closest to the first mirror among the lenses of the projector lens is convex.

The disclosed apparatus is a display panel (with electronic display) made wearable by suspending it from an operator's neck (or shoulder) by a strap and including a prop to push the display panel away from the operator's stomach/chest and into his comfortable view without using of his hands. The bottom end of the prop makes contact with the operator using an interface designed to provide lateral tipping stability and sliding stability in all directions. The display distance from the operator's face may be adjusted by adjusting the strap length. The prop may include an adjustable extension to better position the display. The apparatus may include only electromagnetic communication for computer remote control, may receive television, may connection to multiple sources with a separate telecommunication housing, may include various accessory holders, may include display panel back side controls or may include computer equipment.

Provided is a head-up display which facilitates the differentiation of information contained in a stereoscopic display and which enables display having a stereoscopic effect, by rotating either a first display surface of a first image generation unit corresponding to a first virtual image display surface, or a reflection unit for aiming first display light emitted from the first image generation unit at a front window shield (transmission/reflection unit), to change the angle formed by the first virtual image display surface and a second virtual image display surface.
