Abstract: A system and method for providing assisted safety to an operator of a vehicle using a head-mounted display that provides displayed content and a see-through view of a surrounding environment, includes determining whether the operator is looking through the windshield of the vehicle or is not looking through the windshield, if the user is looking through the windshield, preventing displayed content from being provided within a display field of view of the head-mounted display, thereby providing an unencumbered see-through view of the surrounding environment, if the user is not looking through the windshield, providing displayed content for viewing by the user within the display field of view, and if important information relating to the safety of the vehicle is detected by a system associated with the vehicle while the user is looking not looking through the windshield, interrupting the displayed content and providing an alert to the operator.

Abstract: Head-worn computers with eye-imaging systems include a camera system positioned in a head-worn computer, wherein the camera system is further positioned to capture eye-image light that originates as reflections from a user's eye, wherein the camera system is further positioned to capture eye-image light as a reflection from a partially reflective surface that is positioned in front of an image display in the head-worn computer, wherein image light, from the image display, is transmitted through the partially reflective surface. A processor is adapted to cause the camera system to capture the eye-image light. The processor is further adapted to cause a comparison of the captured eye-image light with a pre-stored eye image of a known user of the head-worn computer. In the event the comparison confirms the identity of the known user, the user is granted permission to view content to be presented in a display of the head-worn computer.

Abstract: Aspects of the present invention relate to methods and systems for imaging, recognizing, and tracking of a user's eye that is wearing a HWC. Aspects further relate to the processing of images reflected from the user's eye and controlling displayed content in accordance therewith.

Abstract: A head-worn computer includes a camera system positioned to capture a surrounding environment in front of a user, a processor that identifies a position of a plurality of light emitters mounted on a hand-held controller from images captured by the camera system and tracks the position of the plurality of light emitters as the hand-held controller moves in the surrounding environment and interprets the tracked position as positional changes of the hand-held controller. The processor uses the position of the plurality of light emitters as markers in three dimensional space, the markers used as an anchor for virtual content presented in a see-through display of the head-worn computer.

Abstract: Disclosure herein concerns a method that includes illuminating a user's eye with an illumination source in a head-worn display, capturing an image of the user's eye with an eye camera in the head-worn display, wherein the image includes an eye glint produced by light from the illumination source that is reflected from a surface of the user's eye, determining a size of an eye glint in the captured image, and identifying a change in focus distance for the user's eye in correspondence with a change in the size of the eye glint.

Abstract: Aspects of the present invention relate to methods and systems for the see-through computer display systems with adjustable-zoom cameras positioned such that their respective capture fields-of-view at least partially overlap at a target distance.

Abstract: Methods and systems may be directed to retrieving personal information relating to a user of a wearable head device, detecting a physical structure at a geo-spatial location, associating a digital content with the geo-spatial location based on at least the detected physical structure, determining whether the user is near the geo-spatial location, and presenting the digital content on a see-through display of the wearable head device. Presenting the digital content on the see-through display may comprise indicating a spatial relationship between the digital content and the physical structure.

Abstract: Aspects of the present disclosure relate to modular expansion systems for use in head-worn computing systems. In an head-worn computer, an electrical connector is adapted to electrically connect with a modular expansion module, wherein the modular expansion module adds a capability to the head-worn computer and is removeably mounted to the head-worn computer, and a mount is adapted to physically secure the modular expansion module to the head-worn computer.

Abstract: A see-through head mounted display with controllable light blocking includes an optics module comprising a light source and image source positioned on a same side of an angled partially-reflective surface, wherein the light source projects light off the surface to the image source which reflects the light as image light to the surface which transmits the image light along a first axis. The display also includes a flat combiner positioned to reflect the image light off of a first side and simultaneously transmit incident light through the first and a second side, along an optical axis perpendicular to the first axis to provide a view of a displayed image overlaid onto a see-through view of the environment, and a controllable light blocking element arranged generally parallel to the flat combiner and in front of the second side to block light incident on the same optical axis as the image light.

Abstract: Aspects of the present invention relate to methods and devices for receiving and presenting content. In an example method, content is received, the content to be delivered to a plurality of recipients. Each recipient of the plurality of recipients has a preference for a respective first physical location at which the content is to be presented on a display of a wearable head device associated with the recipient. A sender of the content has a preference for a second physical location at which the content is to be presented to the respective recipient of the plurality of recipients. A respective final physical location for the presentation of the content for the respective recipient of the plurality of recipients is identified. The respective final physical location is based on the respective recipient's preference and the sender's preference. It is determined whether the respective recipient is proximate to a zone associated with the respective final physical location.

Abstract: A head-worn see-through display includes a display panel adapted to generate image content light, a combiner adapted to reflect the image content light towards an eye of a user, wherein the combiner transmits scene light from a surrounding environment to the eye of the user, and an image expansion optic intermediate the display panel and the combiner. The image expansion optic includes a flat partially reflective and partially reflective surface (the “flat surface”), a curved partially reflective and partially reflective surface (the “curved surface”), and the flat surface adapted to reflect the image content light towards the curved surface and the curved surface adapted to reflect the image light back towards the flat surface, wherein the image light transmits through the flat surface towards the combiner.
