Abstract: Systems, devices, and methods for optical waveguides that are well-suited for use in wearable heads-up displays (WHUDs) are described. An optical waveguide includes a volume of optically transparent material, a first holographic optical element (HOE) and a second holographic optical element, wherein the first HOE and the second HOE are carried by the volume of optically transparent material, and the first HOE is positioned across a width of the volume of optically transparent material from the second HOE. Light enters the optical waveguide and is propagated down a length of the waveguide by reflection between the first HOE and the second HOE. Propagation of the light within the optical waveguide does not require total internal reflection. The optical waveguide may include means to in-couple the light into the waveguide and means to out-couple the light from the waveguide. WHUDs that employ such optical waveguides are also described.

Abstract: Systems, devices, and methods for remote access smartphone services are described. The mobile operating system and smartphone applications are stripped out of smartphone hardware and stored as a virtual smartphone instance at a host server. The virtual smartphone instance remains addressable by a phone number. A specialized portable interface device (such as a smartglasses device, a smartwatch, or an adapted smartphone device) remotely accesses the virtual smartphone instance through a cellular or internet connection and utilizes the smartphone applications to deploy smartphone services, including messaging and phone calling via the phone number. The systems, devices, and methods are extended to include a cellular telecommunications content delivery network comprising multiple portable interface devices all remotely accessing respective virtual smartphone instances corresponding to unique phone numbers, with virtual smartphone instances edge cached in relation to the portable interface devices.

Abstract: Systems, devices, and methods are disclosed for enabling private communication between head-mounted displays. A first user dons a first head-mounted display. The first head-mounted display authenticates that the first user is authorized to view information displayed by the first head-mounted display. In response to positive authentication, the first head-mounted display displays the information to the first user. The first user inputs a selection command via an input interface, such as, for example, gazing at particular information, to select some of the displayed information. The first head-mounted display generates a message based on the user selection, which may be encrypted by the first head-mounted display prior to transmission. The first head-mounted display transmits the message to a second head-mounted display, such that the second head-mounted display displays the message to an eye of a second user wearing the second head-mounted display.

Abstract: A waveguide including at least a first photopolymer layer and a second photopolymer layer having a barrier layer therebetween and a first transparent layer and second transparent layer overlaying the first and second photopolymer layers, respectively. The waveguide can further include at least one holographic incoupler and at least one holographic outcoupler, each configured to be responsive to light within a first waveband and unresponsive to light outside of the first waveband, and further configured to be transmissive or reflective.

Abstract: Systems, devices, and methods for eyebox expansion in wearable heads-up displays (“WHUDs”) are described. The WHUDs described herein each include a projector and an optical waveguide positioned in an optical path between the projector and an eye of the user. For any given light signal from the projector, the optical waveguide receives the light signal at an input coupler and outputs multiple instances or copies of the light signal from multiple discrete, spatially-separated output couplers. The multiple instances or copies of the light signal may be converged by the optical waveguide directly to respective exit pupils at the user's eye or may be routed by the optical waveguide to a holographic combiner in the user's field of view from which the light signals may be converged to respective exit pupils at the user's eye. The optical waveguide employs exit pupil replication to expand the eyebox of the WHUD.
