Optical Module for Head-Mounted Device

An optical module for a head-mounted device that is configured to present content to a user, the optical module comprising:

• an optical module housing assembly that defines an internal space;
• a lens that is connected to the optical module housing assembly;
• a display assembly that is connected to the optical module housing assembly, wherein the display assembly is configured to cause the content to be displayed to the user through the lens;
• and
• an infrared emitter that is located between the lens and the display assembly in the internal space of the optical module housing assembly, wherein the infrared emitter is configured to emit infrared radiation through the lens.

A head-mounted device that is configured to present content to a user, comprising:

• a housing;
• a first optical module that is located in the housing;
• a second optical module that is located in the housing;
• an interpupillary distance adjustment assembly that supports the first optical module and the second optical module with respect to the housing to allow adjustment of a distance between the first optical module and the second optical module;
• a first front-facing camera that is connected to the first optical module and is movable in unison with the first optical module by the interpupillary distance adjustment assembly;
• and
• a second front-facing camera that is connected to the second optical module and is movable in unison with the second optical module by the interpupillary distance adjustment assembly,
• wherein adjustment of the distance between the first optical module and the second optical module by the interpupillary distance adjustment assembly also adjusts a distance between the first front-facing camera and the second front-facing camera.
