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 device and the portable electronic device.

A head-mounted display system includes a head-mounted display unit and a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use. The positioning and stabilising structure includes a rear support structure adapted to contact posterior regions of a user's head and at least one connector structured and arranged to interconnect the rear support structure to the head-mounted display unit. The rear support structure is in the form of a hoop comprising an occipital portion configured and arranged engage the user's head along a portion of the occipital bone adjacent a junction where the neck muscles attach to the occipital bone in use.

A head-mounted display system includes a head-mounted display unit and a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use. The positioning and stabilising structure includes a rear support structure adapted to contact posterior regions of a user's head and opposing temporal connectors structured and arranged to interconnect the rear support structure to the head-mounted display unit, the opposing temporal connectors adapted to be disposed on opposing sides of the user's head and extend along the temporal regions of the user's head. At least the rear support structure comprises a textile material configured to conform to the posterior regions of the user's head.

The present disclosure relates to cantilevered imaging modality wearable optical systems that provide for optimal ergonomics coupled with vision enhancement and vision magnification. Methods of use, devices, and kits are also contemplated.

An electronic device such as a head-mounted device may have a transparent member supported by head-mounted support structures. Optical sensors such as time-of-flight sensors and other optical sensors may have light-emitting components and light-detecting components. A stray light blocking structure may be formed in the transparent member. The stray light blocking structure may be configured to block stray light that is traveling laterally through an interior portion of the polymer layer. This prevents the stray light from being received by the light-detecting detecting device. The stray light blocking structure may formed by providing the polymer layer with light redirecting structures such as protrusions and/or recesses. Light-absorbing coatings and/or patterned surfaces such as textured surfaces may be incorporated into the stray light blocking structure.

A facial-interface system for a head-mounted display may include a facial interface and a facial-interface adjustment apparatus. The facial-interface adjustment apparatus may include (1) a coupling mount for coupling the facial-interface adjustment apparatus to a head-mounted-display housing, (2) an adjustment protrusion that is movable between a plurality of holding positions relative to the coupling mount, the adjustment protrusion having a facial-interface coupling portion coupled to the facial interface, and (3) a spring that biases the adjustment protrusion in a biasing direction toward the facial interface such that the adjustment protrusion moves between separate holding positions of the plurality of holding positions following application of a compressing force to the adjustment protrusion compressing the spring in a compressing direction opposite the biasing direction. Various other systems, devices, and methods are also disclosed.

An imaging system for a smartphone includes a housing configured to rigidly attach to a handheld smartphone device. The system further includes an arm extending from the housing, wherein the arm is configured to be adjustable such that the arm is movable toward and away from the housing. Additionally, the system includes a sample mounting portion attached to the arm, the mounting portion having a retaining device, wherein the retaining device is configured to secure a target sample, the mounting portion configured to direct an image of the target sample to a first camera in the handheld smartphone device.

The invention relates to an image generating device (20) comprising: at least one light source (23), a screen (21) designed to be backlit by said light source, and a reflector (25) arranged between said light source and screen and designed to reflect at least some of the light emitted by the light source. According to the invention, the reflector defines a housing (280) designed to receive the screen such that the reflector has a zone (290) of thermal contact with the screen. The invention also relates to a head-up display comprising an image generating device of this type.
