    Abstract: There is provided a method of operating a wearable heads-up display (WHUD). The WHUD may include a light source, a spatial modulator, and a display optic. The method may include generating, by the light source, an output light to form an image viewable by a user of the WHUD. The method may also include receiving a position of a pupil of the user relative to an eyebox of the WHUD, and obtaining an image correction map based on the position of the pupil. Moreover, the method may include adjusting the output light to form an adjusted output light. The adjusted output light may be adjusted based on the image correction map to reduce at least one of an intensity non-uniformity and a color balance non-uniformity of the image. The method may also include directing, by the display optic, the adjusted output light into a field of view of the user.

    Abstract: Systems, devices, and methods for increasing resolution in wearable heads-up displays (WHUD) are described. A WHUD includes a support structure, a scanning laser projector (SLP), a fold mirror, a split mirror, an optical splitter, and an optical combiner. When the WHUD is worn on the head of a user, the optical combiner is positioned in a field of view of the user. The SLP scans light signals onto the fold mirror which reflects light onto one of at least two reflective surfaces of the split mirror, based on a state of the fold mirror. The split mirror redirects the light signals onto the optical splitter, which, in turn, redirects the light signals towards the optical combiner. The optical combiner redirects the light signals to the eye at exit pupils containing the full usable resolution of the SLP.

    Abstract: Systems, devices, and methods for accommodating multiple sets of laser light sources in an optical engine of a display system such as a laser projection system are described. Laser light beams may be combined via wavelength-, polarization-, and/or angular-separation-based techniques. First and second sets of laser light beams may be angularly separated such that different sets of partially overlapping pixels are projected by the system, thereby increasing the display pixel density and/or an expanding the field of view of the display. One or more laser die may be mounted to each submount of the optical engine. For embodiments with two laser dies on each submount, collimating lenses may introduce angular separation between laser light beams output by each pair of commonly mounted laser dies. A retroreflector prism may be disposed at a beam combiner to provide a compact extension of the optical path through the beam combiner.

    Abstract: Systems, devices, and techniques are provided for displaying graphical content by modulating an intensity of one or more emitted light beams while redirecting those emitted light beams along a scan path that includes multiple locations of a projection surface Timing information that specifies timing values associated with each of multiple locations on a projection surface of an optical element is received or generated. One or more light beams that each have a respective intensity are emitted, and redirected along a scan path that includes at least some of the multiple locations. During the redirection of the one or more emitted light beams, the respective intensity of each of the one or more emitted light beams is modulated in accordance with the timing information to display one or more pixels of an image at each of the at least some multiple locations.

    Abstract: Systems, devices, and methods for driving projectors are described. The actual area projected over by a laser projector for a given pixel may not exactly match a desired projection area for the pixel, especially at edge regions of an image. In the present systems, devices, and methods, projection data is provided for at least one image to be projected by a laser projector. The projection data can include sets of alternative data sections at edge regions of the at least one image, effectively increasing resolution for the edge regions of the image. Depending on a projection pattern being used by a laser projector at a given time, select alternative data sections can be projected which closely match the actual area covered by the projection pattern, improving image quality.

    Abstract: There is provided a method including receiving an incoming ID at a first wearable heads-up display (WHUD), which incoming ID is associated with a communicant device. The method also includes sending match data from the first WHUD to a match engine. The match data includes a first WHUD ID and the incoming ID. Moreover, the method includes receiving a match indicator at the first WHUD from the match engine. The match indicator is to indicate a match event between the first WHUD and the communicant device based on the match data. Furthermore, the method includes effecting communication between the first WHUD and the communicant device comprising at least one of sending a message from the first WHUD to the communicant device and receiving at the first WHUD a corresponding message from the communicant device. The first WHUD, and a method of operating the match engine are also described.
