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.

Abstract: A virtual image is displayed to a user via a light engine (211) to generate a display light representing the virtual image, a diffractive waveguide (235), and an incoupler (231) and outcoupler (234) that are each optically coupled to the diffractive waveguide (235). In operation, the incoupler (231) receives the display light from the light engine (211) and directs the received display light into the diffractive waveguide (235) and to one or more multidimensional intermediate gratings (232. 233). The multidimensional intermediate gratings (232, 233) redirect the display light through the diffractive waveguide (235) to the outcoupler (234), which in turn redirects at least a portion of the display light out of the diffractive waveguide (235) to an eye (291, 293) of the user.
