1. A near-eye display device, comprising:
an eye tracking system configured to determine a position of an eye of a user relative to the near-eye display device;
a waveguide including at least an input coupler and an output coupler, the output coupler including a plurality of zones, each zone activatable via a dynamically controllable output coupling element of the zone;
an image source configured to output image light to the input coupler; and
a controller configured to selectively activate one or more zones of the output coupler based at least on the position of the eye.
