1. An electronic device configured to be used in a mixed reality system with a mixed reality device that has a depth sensor, emits light, and captures images that include the emitted light after the emitted light has reflected off of objects, comprising:
a housing;
control circuitry in the housing;
a display in the housing, wherein the housing has a first surface opposite the display and an opposing second surface; and
a marker on the housing that is formed from a patterned retroreflective coating that reflects the emitted light toward the depth sensor when the depth sensor emits the light towards the marker, wherein the marker is one of a plurality of markers that are formed in a ring that runs along a periphery of the housing on the first surface.
