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 handwriting support device includes a half mirror; an image display surface; a writing surface, a virtual image of an image displayed on the image display surface being projected on the writing surface. In a case where a real object is inserted onto the writing surface, the image display control unit causes a non-display processed image to be displayed on the image display surface, the non-display processed image being obtained by at least a partial region, of a region of the first image corresponding to a vertically projected region of the real object on the writing surface, being subjected to non-display processing. In the handwriting support device, an image, which is a virtual image of the non-display processed image in which at least a part of an inside of the vertically projected region of the real object is non-displayed, is projected onto the writing surface.

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 a forehead support connector, which includes a forehead support strap, which extends generally along and in the direction of the sagittal plane and connects the rear support structure to a superior edge region of the head-mounted display unit. The forehead support connector further includes a forehead support rigidiser that provides rigidification to a portion of the forehead support connector.

Disclosed are a head mounted display (HMD), and a method for controlling the same. The HMD includes: a body having a display unit; a lens driving unit provided at the body, and configured to move a lens unit spaced apart from the display unit, wherein the lens driving unit includes: a lens frame having a first tube portion protruded in a first direction, and coupled to the body; a lens housing having a second tube portion protruded in the first direction and having the lens unit, the second tube portion relatively moved on the first tube portion; a link unit coupled to the lens frame and the lens housing, and configured to move the lens housing; and a driving unit provided at one side of the first tube portion, and configured to operate the link unit.

An optical instrument indexing device includes a riser and first and second platform. The first platform is disposed on a first side of the riser at a first position on the riser. The second platform disposed on a second side of the riser at a second position on the riser. Both the first and second platforms are indexed or indexable to align two optical instruments to a field of view.

An illumination system includes a surface configured to have an imaging target placed thereon, a light source, a beam splitter and at least a first mirror. The beam splitter is configured to split the beam of light from the light source and the first mirror is configured to reflect a first beam from the beam splitter onto the surface with the imaging target. An imaging system includes an imaging surface configured to have an imaging target placed thereon, a mirror, and a capturing device. The capturing device is configured to capture an image of the imaging target through a path of emitted light that extends from the imaging target, reflects off the mirror, and to the capturing device. The mirror, the capturing device, or both are configured to move in a diagonal direction with respect to the imaging surface to reduce a length of the path of emitted light. Systems and methods to calibrate an imaging system to remove or reduce non-uniformities within images of samples due to imaging system properties. Illumination modules and systems for more uniform illumination of samples placed on sample screens or illumination surfaces comprising frosted half-cylindrical rods and methods of use thereof.

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.

A head mounted display (HMD) including a lens of optics configured for viewing virtual reality (VR) content. The HMD includes a display screen disposed behind the lens of optics such that the lens of optics is between the display screen and an eye of a user when the HMD is worn by the user, wherein the display screen is configured for rendering the VR content. The HMD includes a support structure configured to fit around a head of the user when worn, wherein the lens of optics and display screen is disposed within the support structure such that the display screen is located in front of the eye when the HMD is worn. The HMD includes a heating component disposed in the support structure, wherein the heating component is controllable to provide heat in response to an environmental cue in the VR content displayed on the display screen.

A mixed reality assembly includes a curved mirror, a display apparatus, a motion detection module, and a display control module. The display apparatus is within a focal length of the curved mirror and has a display surface facing the curved mirror. The motion detection module is configured to detect a motion of a real object. The display control module is configured to control a display image on the display surface in response to the detected motion of the real object.
