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 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: Aspects of the present invention relate to methods and systems for measuring and managing the brightness of digital content in a field of view of a head-worn computer.

Abstract: Embodiments include a head-worn computer comprising, a front frame mechanically adapted to secure a see-through computer display; an arm, secured to the front frame, mechanically adapted to secure the front frame to the head of a user; and the arm comprising an internal speaker system, enclosed by the arm, wherein the internal speaker system comprises a back cavity and a speaker, the arm further comprising an inlet vent positioned to vent the back cavity and an audio outlet vent positioned to vent the speaker.

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: An external user interface adapted to control a head-worn computer includes a housing with a mechanical attachment system adapted to secure the housing to a steering wheel of a vehicle, a programmable quick launch software application button mounted on the housing and adapted to activate a pre-designated software application on the head-worn computer, and a button mounted on the housing and adapted to remove all content from being displayed in the head-worn computer when activated.

Abstract: Aspects of the present invention relate to methods and systems for providing high quality display images in see-through head-worn optics.

Abstract: Aspects of the present disclosure relate to visual presentation techniques for micro-Doppler signatures. A method may include receiving a micro Doppler signature indicative of a projectile flight path, identifying a beginning trace marker and a termination trace marker, and presenting in a head-worn computing system field of view digital content representative of the projectile flight path, wherein the beginning trace marker and termination trace marker provide a world-lock perspective for a wearer of the head-worn computing system such that the digital content appears to remain referenced to the environment independent of a position of the head-worn computing system.

Abstract: Embodiments include a head-worn display including a display panel sized and positioned to produce a field of view to present digital content to an eye of a user, and a processor adapted to present the digital content to the display panel such that the digital content is only presented in a portion of the field of view, the portion being in the middle of the field of view such that horizontally opposing edges of the field of view are blank areas. The processor is adapted to shift the digital content into one of the blank areas to adjust the convergence distance of the digital content and thereby change the perceived distance from the user to the digital content.

Abstract: Embodiments include an eye cover adapted to be removeably mounted on a head-worn computer with a see-through computer display where the eye cover includes a flexible audio headset mounted to the eye cover. The flexibility of the audio headset provides the user of the head-worn computer with a mechanism to align the audio headset with an ear of the user.

Abstract: Aspects of the present invention relate to methods and systems for calibrating the position of content in a see-through head-worn display.

Abstract: Aspects of the present invention relate to providing see-through computer display optics.

Abstract: Aspects of the present invention relate to methods and systems for the see-through computer display systems with a wide field of view.

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 method, includes pre-setting a geo-spatial location where content will be displayed to a user of a see-through head-worn display, establishing a region proximate the geo-spatial location; and causing a marker recognition system of the head-worn see-through display to activate when data indicates that the see-through head-worn display is within the region, wherein the marker recognition system monitors a surrounding environment to identify a marker that will act as a virtual anchor for the presentation of the content.

Abstract: Aspects of the present invention relate to a compact optics module for a head mounted display including a DLP image source comprising a polarized light source providing illumination light, a flat reflective polarizer to reflect the illumination light toward the DLP image source and transmit image light, wherein the illumination light is provided at an angle to the DLP, a quarter wave retarder to change the polarization state of the illumination light as it is reflected by the DLP image source thereby providing image light, at least one light trap to absorb a portion of off-state image light, a lens element to provide a viewable field of view of on-state image light in an image displayed by the DLP image source, and a combiner to reflect the on-state image light toward a user's eye and provide a see-through view of a surrounding environment.
