The present invention provides a head mounted device. Said head mounted device includes a visual reality helmet (1), a control section (2), a transmission line (4) and a head band portion. Said visual reality helmet (1) includes a mask proximate to user's face and a display screen in front of the mask. The control section (2) is connected with the visual reality helmet (1) as a whole via the transmission line (4), in order to control the operation of the head mounted device. The head band portion is intended to mount this visual reality helmet (1) onto the head of a user. By providing a control section (2) to be connected with the visual reality helmet (1), the head mounted device disclosed herein does not need to connect with other peripheral devices and thus enhance the portability and the compatibility thereof. In preferred embodiments, by providing a microphone (10) and a camera module so as to enhance the man-machine interaction capability of the head mounted device; by providing an earphone seat (3) on the transmission line (4), and by providing a rotatable head band (6) and an adjusting head band which are detachable and adjustable, the comfort of wearing this head mounted device is improved.

A modular electronic communication system is disclosed with interchangeable components attachable on eyewear. A plurality of pre-existing eyewear models can each be retrofitted by attachment of one or more of such interchangeable components to that eyewear. Such components can be configured for custom attachment with a particular eyewear or such components can be configured for universal attachment with one or more different eyewear models. The communication system can be configured to produce an adjustable heads-up display for the wearer of the eyewear. The electronic communication system can comprise a plurality of interchangeable, electronically interconnected components, such as a first optical module, a first base module, a base link, a second base module, and/or a second optical module. In some embodiments, one or more or all of the components of the electronic communication system are integrally and permanently attached to an eyewear and are not interchangeable or modular.

A head-mounted display (HMD) includes various features that allow for customizing the HMD to different users. The HMD may include an interpupillary distance (IPD) adjustment mechanism that includes a double biasing assembly for smooth, controlled adjustment of the spacing between lens tubes. The HMD may include a field of view (FOV) adjustment mechanism that includes first and second gear assemblies connected via a connecting rod to allow uniform adjustment of the spacing between the lenses and the user's face. The HMD may further include a swappable face gasket, a swappable visor, a removable head strap, and a modular accessory compartment for further customizations to the HMD. The HMD may further include inconspicuous spectrum-transmissive windows that are made with a spectrum-transmissive base material for the HMD housing that is coated with a spectrum-opaque material, and the spectrum-opaque material is selectively removed to create the spectrum-transmissive windows.

A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment vary for different users and may change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes by determining whether features of the eye are at certain vertical positions relative to the HMD. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, and provides feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.

Disclosed are various embodiments regarding a head-mounted device. According to an embodiment, a mount device comprises: a housing comprising a front surface, a rear surface that can be mounted on a head, and a side surface surrounding the front surface and the rear surface; a coupling portion can be disposed in housing, and can be configured to be coupled so as to slope an external electronic device at a designated angle with regard to the side surface; a prism comprising a first surface capable of facing, at the designated angle, at least a part of a display included in the external electronic device that can be coupled to the coupling portion, a second surface capable of changing (through total reflection) the direction of light that is incident from the display through the first surface, and a third surface capable of emitting the light, the direction of which has changed; a mirror arranged between at least a part of the side surface and the third surface; and a splitter arranged between the mirror and the third surface to be capable of transmitting at least a part of light emitted through the third surface and changing the direction of the light, which is transmitted and then reflected by the mirror, to a direction corresponding to the rear surface. Various other embodiments are possible.

A detachable projection device, a sealing housing thereof, and a wearable apparatus are provided. The sealing housing includes a first cover, a second cover, a first waterproof and dustproof gasket having an enclosed loop-shape, and a transparent case. The first cover and the second cover respectively have two sealing edge portions corresponding in shape to each other. The second cover is detachably fastened to the first cover, and the first waterproof and dustproof gasket is gaplessly sandwiched between and abutted against the two sealing edge portions, so that the first cover, the second cover, and the first waterproof and dustproof gasket jointly define an accommodating space. The transparent case is connected to the second cover and has an insertion slot that is in spatial communication with an optical area of the accommodating space.

Illumination devices as include a frame intended to be worn by a user and one or more light sources (e.g., LEDs) positioned by the frame so as to be near a user's zygomatic bones and oriented to project light in a direction of the user's view when the illumination device is worn on the wearer's head. The frame may be shaped to be worn over the user's ears and behind the user's head, and may be made of one or more of plastic, metal and/or a metal alloy, carbon fiber, wood, cellulose acetate, natural horn and/or bone, leather, and an epoxy resin. An optional strap may be retractably attached to connect portions of the frame over the wearer's head. The LEDs may be included in respective panels swivelly mounted to booms of the frame and the panels may further include imaging devices, such as a camera, and/or a projector.

An assortment of Cognitive Load Reduction (CLR) systems is disclosed. The systems are worn by a user, rather than appearing on displays in front of the user. This arrangement allows the systems to be movable and less confining. This in turn results in the wearer employing the CLR systems in a wider variety of environments than earlier mechanisms.
