An interface device is provided that is configured to allow viewing of three-dimensional (3-D) content when the interface device is worn. In certain embodiments, a wearable visualization device can be removably coupled to the interface device. The wearable visualization device, when in use, may provide additional viewing functionality, such as facilitating the viewing of augmented reality (AR) or virtual reality (VR).

A head-up display includes: a display device that emits image light; a mirror that reflects the image light; a mirror holder that includes a rotating shaft; and a bearing that rotatably supports the rotating shaft. The mirror holder supports the mirror from a back surface side of the mirror. The rotating shaft comprises a first rotating shaft located outside a perimeter of the mirror as viewed from the back surface side of the mirror, and a second rotating shaft located inside the perimeter of the mirror as viewed from the back surface side of the mirror. The second rotating shaft is provided on an axis same as an axis of the first rotating shaft. The bearing supports the first rotating shaft and the second rotating shaft.

An image display apparatus includes an electronic circuit board having a light modulator; a holder with which at least a portion of the light modulator is in contact in a direction of an optical axis; and a supporter secured to the holder and in contact with the electronic circuit board in a state in which a gap is provided between the electronic circuit board and the holder along the direction of the optical axis.

A head-mounted device is provided. The head-mounted device includes a longitudinal headband, a horizontal headband unit and a headband adjustment mechanism. The headband adjustment mechanism is connected to the longitudinal headband and the horizontal headband unit. In a first configuration, the headband adjustment mechanism is adapted to adjust the tightness of the horizontal headband unit. In a second configuration, the headband adjustment mechanism is adapted to adjust the tightness of the longitudinal headband.

A virtual or augmented reality headset is provided having a frame, a pair of virtual or augmented reality eyepieces, and an interpupillary distance adjustment mechanism. The frame includes opposing arm members and a bridge positioned intermediate the opposing arm members. The adjustment mechanism is coupled to the virtual or augmented reality eyepieces and operable to simultaneously move the eyepieces to adjust the interpupillary distance of the eyepieces.

A heads-up display for viewing by an eye of a passenger of a vehicle includes a windshield with a reflective polarizer disposed adjacent to a first outermost glass surface of the windshield, a display configured to emit an image toward the windshield, the windshield reflecting between 15% and 85% of the emitted image toward the passenger, and a phase retarding plate disposed in an optical path between the display and the windshield. The windshield is configured to receive the image emitted by the display after the image has been transmitted by the phase retarding plate and to reflect at least a portion of the received image as a reflected image toward the eye of the passenger. The phase retarding plate modifies a polarization state of the reflected image to improve a viewing characteristic of the reflective image depending on a viewing angle of the eye of the passenger.

An optical display, including a first waveguide having a first set of surfaces, an input grating, a fold grating, and an output grating; an image input image node assembly; and a prismatic relay optics is provided. The prismatic relay optics may be configured to be optomechanically connected to the waveguide and the input image node assembly. The optical display is may also be configured to operate alone or as integrated with a headpiece to be used as a HUD. The HUD may have a first and a second configuration wherein the waveguide is decoupled or coupled.

Embodiments disclosed herein relate to a heads-up display visor for a vehicle, such as an automobile, to provide driver assistance information to the driver. Features include a display screen that is sized and positioned relative to the driver's conventional sun visor, so as to eliminate the need to project images onto the windshield and/or to have a projector located on the vehicle dashboard. In certain embodiments, the heads-up display visor is portable, and is affixed to the driver's conventional sun visor by a clip, thereby allowing a driver to move the device from one vehicle to another.

Head-mounted display systems and methods of operation that allow users to couple and decouple a portable electronic device such as a handheld portable electronic device with a separate head-mounted device (e.g., temporarily integrates the separate devices into a single unit) are disclosed. The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted de ice and the portable electronic device.

A cable includes multiple internal cables configured to transmit electrical signals, an outer jacket that houses the internal cables, and round portions formed proximate to opposite end regions of the cable, wherein the internal cables are arranged to circumferentially surround a center axis in the round portions. In addition, the cable includes a flat portion positioned between the round portions of the cable, wherein the internal cables are arranged in a row across the flat portion.
