A head-mounted device includes a first device portion and a second device portion. A first coupler portion of the first device portion is connectable to a second coupler portion of the second device portion to define a connected position in which the first device portion is connected to the second device portion and a disconnected position in which the first device portion is disconnected from the second device portion. A second adjuster portion of the second device portion causes a first adjuster portion of the first device portion to move a first optical module and a second optical module in response to movement of the first device portion and the second device portion from the disconnected position to the connected position.

The present invention presents an optical apparatus and a method for combined use of at least two independent optical observation devices. At least two different and independent optical monoculars, designed for operating independently from each other in different light spectrumparts, are combined together. The independent optical monoculars are linked mechanically and electronically into a single optical system. At least two independent viewfinders and processors are electronically linked to each other. Electronic connection can be provided wired or wireless. The method for combined use of optical monoculars generates a single fused image from different light spectrum parts. An improved and detailed images are generated, which include data from different light spectrum parts. The fused image is generated dynamically in a real time mode. Signals from Near Infrared, visible light, ultraviolet light, Midwave Infrared, Longwave Infrared, Shortwave Infrared and other light spectrum parts could be combined into a single fused image.

A head-mounted device may be provided with displays. The displays and lenses through which images on the displays are viewed may be mounted in optical modules. Positioners may be used to move the optical modules towards and away from each other to adjust the head-mounted device to accommodate different user interpupillary distances. To support and guide the optical modules, the optical modules may be slidably mounted to guide rails. The guide rails may be biased against the optical modules using biasing systems. By using the biasing systems, misalignment between the optical modules can be reduced. If desired, guide rail sensors may be used to monitor the positions of the guide rails. In some configurations, the optical modules may be mounted to the guide rails using kinematic mounting.

A driving method, suitable for a multimedia system including a head-mounted device (HMD), includes the following operations: retrieving human factor data from a storage device, a radio signal, or an image; and according to the human factor data, automatically adjusting software for driving the HMD or hardware components of the multimedia system.

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 headset includes a housing, an optical assembly disposed in the housing, and an adjustment assembly coupling the optical assembly to the housing. The optical assembly includes a first lens and a second lens spaced from the first lens by a first distance. The adjustment assembly includes an interpupillary distance adjustment mechanism and an eye relief distance adjustment mechanism. The interpupillary distance adjustment mechanism is configured to adjust the first distance between the first lens and the second lens along a first axis. The eye relief distance adjustment mechanism configured to adjust the optical assembly a second distance along a second axis orthogonal to the first axis.
