1. An assembly, comprising:
a laser projector configured to project images;
a waveguide configured to redirect light to generate a data structure representing a three-dimensional map of a space;
at least one head mount (HM) with at least one sensor to generate signals representing a gaze direction of a wearer of the HM, the waveguide being configured to move according to the signals to project images in the space using the data structure; and
at least one processor for controlling the waveguide and programmed with instructions to:
based at least in part on the data structure representing the three-dimensional map of the space, identify that at least a first region in the space and distanced from the HM and identified by the signals representing the gaze direction of the wearer of the HM is not suitable for presenting the images; and
responsive to identifying that the first region is not suitable for presenting images, control the waveguide to direct the images onto a second region in the space.
