1. A system for projecting an image, the system comprising:

  • a frame to removably receive a plurality of projection surfaces, one at a time, each of the plurality of projection surfaces comprising a holographic optical element (HOE) at a location on the respective projection surface to reflect a projected image for a select interpupillary distance (IPD) when the respective projection surface is received in the frame, each HOE different in location and/or optical characteristics compared to the other HOEs; and

    a projection system coupled to the frame, the projection system comprising;

    a projector to project light onto a first select one of the plurality of projection surfaces received in the frame; and

    a controller to receive an information element including an indication of an IPD of a user, determine a location of the HOE of the select one of the plurality of projection surfaces based on the indication of the IPD of the user, and send a control signal to the projector to cause the projector to project an image in onto the location of the HOE of the select one of the projection surfaces.
