Abstract
Systems, devices, and methods for wearable heads-up displays (WHUD) are described. A WHUD includes a front frame with two openings each with one recess which extends along at least a portion of the periphery of the openings, two arms including frame portions and temple portions, two lenses, a projector to generate light, and a holographic optical element (HOE) carried by a lens to redirect light to an eye of a user. Frame portions insert into the recesses and are held in place when the lenses are inserted into the recesses, wherein when the WHUD is assembled the projector and HOE are positioned correctly to create a display for the user. The assembled WHUD is inflexible where the front frame and arms are attached such that when worn the projector maintains a fixed position relative to the HOE and the display remains undistorted and visible to the user.
