Abstract
Methods of assembling a head-mounted display may include supporting a head-mounted display frame, digitally adjusting an optical coordinate system of an optical sensor to align the optical coordinate system with a frame coordinate system of the head-mounted display frame. After the optical coordinate system is aligned with the frame coordinate system, a projector assembly may be moved to align a projected image with the optical coordinate system. The aligned projector assembly may then be secured to the head-mounted display frame. Various other methods and systems are also disclosed.

A method of assembling a head-mounted display, the method comprising:
- supporting a head-mounted display frame with a support mechanism;
- determining a location and orientation of a frame coordinate system of the head-mounted display frame relative to the support mechanism;
- digitally adjusting an optical coordinate system of an optical sensor to align the optical coordinate system with the frame coordinate system to within a predetermined threshold;
- moving, with at least one projector holder, at least one projector assembly to align a projected image of the at least one projector assembly with the optical coordinate system of the optical sensor to within another predetermined threshold, different than the predetermined threshold;
- and
- securing the aligned at least one projector assembly to the head-mounted display frame.
A method of assembling a head-mounted display, the method comprising:
- digitally aligning an optical coordinate system of an optical sensor with a frame coordinate system of a head-mounted display frame to within a predetermined threshold;
- mechanically aligning a projected image of at least one projector assembly with the optical coordinate system of the optical sensor to within another predetermined threshold, different than the predetermined threshold;
- and
- after digitally aligning the optical coordinate system with the frame coordinate system and the projected image with the optical coordinate system, securing the at least one projector assembly to the head-mounted display frame.
A system for assembling a head-mounted display, comprising:
- at least one optical sensor having an optical coordinate system;
- a support mechanism configured for supporting a head-mounted display frame in a fixed position relative to the at least one optical sensor;
- at least one computer processor configured to digitally adjust the optical coordinate system to align the optical coordinate system with a frame coordinate system of the head-mounted display frame to within a predetermined threshold;
- and
- at least one projector holder that is spatially manipulable, the projector holder configured for holding and moving at least one projector assembly to align a projected image of the at least one projector assembly with the optical coordinate system.
