In one method, device data including an orientation of a targeting device is received in a computing system. Target coordinates of the targeting device as projected onto a field-of-view of a display device are then located based on the device data. Pursuant to locating the target coordinates within a predefined margin, a target graphic indicating the target coordinates is superposed onto the field-of-view. Pursuant to locating the target coordinates outside of the predefined margin, an off-target graphic is superposed onto the field-of-view and aligned to a display perimeter of the display device.

A helmet mounted display system is described. A visor has an inner reflective surface and is mountable to head gear. A light source is arranged to emit light. Directing optics are arranged to image light from the light source onto the inner reflective surface of the visor to provide a reticle image on the inner reflective surface of the visor. An eye tracker is configured to determine the orientation of an eye of a wearer of the head gear. A controller is configured to receive an indication of the determined orientation of the eye, and to control the at least one actuator to change the orientation and shape of the directing optics to change the position of reticle image based on the indication of the determined orientation of the eye such that the eye views the reticle image.

An inter-pupillary distance (IPD) adjustment mechanism for a head-mounted display (HMD) is disclosed. The IPD adjustment mechanism is coupled to a structural plate of the HMD and to an eyecup for each eye that includes a lens and display assemblies. The IPD adjustment mechanism includes an arm for each optical assembly, and a gear that interfaces with the arms. In one embodiment, each arm is a rack gear that interfaces with a pinion gear. The eyecups are each mounted on one or more rails that allow for the eyecups to adjust a distance between the eyecups along a single dimension. Accordingly, movement of the gear causes both eyecups to move either away from or towards each other. In some embodiments, the IPD adjustment mechanisms is driven by a motor. In some embodiments, the IPD adjustment mechanism is manually controlled by the user.

In one aspect, an eye shield for a respirator mask of the type having a face piece adapted to fit over the face of a user is provided. The eye shield includes a visor assembly including a visor surrounded by a frame, the visor assembly configured to be removably mounted in an opening in the face piece. One or more fastener elements are provided on the frame for removably securing the visor assembly to the face piece. The visor is formed of a transparent material which filters electromagnetic energy emissions at one or more preselected wavelengths. In certain embodiments, one or more head up display assemblies are attached to the visor assembly for projecting a human viewable image to the visor.

A head-mounted display (HMD) system includes an HMD device wearable upon a head of a user, and a peripheral device that is dockable with the HMD device. The peripheral device comprises a plurality of light source elements disposed along a perimeter of a face of the peripheral device and a peripheral electronic control system. The peripheral electronic control system is configured to form an optically detectable light pattern with the plurality of light source elements by controlling each of the light source elements. The HMD device is configured to detect the optically detectable light pattern with a camera and to display an augmented reality (AR) content based on the identified optically detectable light pattern.

The present invention minimizes a structure where an optical driving unit and a camera unit are mounted, thereby contributing compactness of an electronic device and reduction in power consumption. The electronic device includes an image source panel configured to form image light, an optical driving unit having the image source panel therein and configured to provide the formed image light, a display unit configured to output the image light provided from the optical driving unit, a camera unit comprising an image sensor configured to photograph a subject, and an optical unit Printed Circuit Board (PCB) on which the image source panel and the image sensor are mounted.

A problem in the helmet-type electronic device in which the image of the content cannot be formed in the correct position due to the difference of the physical condition of each user is addressed to provide an electronic device comprising a helmet-shaped case configured to be mounted to support at least one region of a head of a user, an optical driving unit including an image source panel provided in the case to form image light, a lens unit located in an emission path of light output from the optical driving unit so that an image of the light is formed on an eye of the user, and a hinge unit for hinge-connecting one side of the lens unit to the case so that the lens unit is rotated to open and close with respect to the case.

System and method for use of mixed and augmented reality Imaging surgical suite and an augmented reality device are provided. A 2D/3D virtual grid having a head-up display with augmented reality is provided. The head-up display can display a 2D radiographic image or 3D volumetric representation or shape model of image, and can further display an augmented reality grid/indicator which can be depicted as a grid, implant, instrument or bone avatar/figure representing shapes, orientations, and positions relative to an anatomical image or model. The augmented reality indicator can be displayed directly in a surgeon's field of view to provide a live, intra-operative situational environment and navigational guidance for the surgeon. The head-up display can show avatar grids/indicators that are outside of the surgeon's field of view within a patient's body.
