Abstract
The disclosed methods of assembling a head-mounted display may include supporting a head-mounted display frame, moving the head-mounted display frame to align a frame coordinate system with a fixed optical coordinate system, holding a projector assembly, and moving the projector assembly to align a projected image with the fixed optical coordinate system. The aligned projector assembly may be secured to the aligned head-mounted display frame. Various other methods and systems are also disclosed.
Claims18
A method of assembling a head-mounted display, the method comprising:
- supporting a head-mounted display frame with a support mechanism that is spatially manipulable relative to a fixed optical coordinate system of an optical sensor, the support mechanism includes a fixture, wherein:
- a surface of the fixture directly interfaces with a corresponding surface of the head-mounted display frame and an opposing surface of the fixture directly interfaces with the support mechanism, and
- the fixture has a shape that complements an additional shape of the head-mounted display frame;
- moving, with the support mechanism, the head-mounted display frame to align a frame coordinate system of the head-mounted display frame to the fixed optical coordinate system of the optical sensor to within a first predetermined threshold;
- holding at least one projector assembly with at least one projector holder that is spatially manipulable relative to the fixed optical coordinate system of the optical sensor;
- moving, with the at least one projector holder, the at least one projector assembly to align a projected image of the at least one projector assembly with the fixed optical coordinate system of the optical sensor to within a second predetermined threshold;
- and
- securing the aligned at least one projector assembly to the aligned head-mounted display frame.
A method of assembling a head-mounted display, the method comprising:
- mechanically aligning, with a spatially manipulable support mechanism, a frame coordinate system of a head-mounted display frame with a fixed optical coordinate system of an optical sensor to within a first predetermined threshold, the support mechanism includes a fixture, wherein:
- a surface of the fixture directly interfaces with a corresponding surface of the head-mounted display frame and an opposing surface of the fixture directly interfaces with the support mechanism, and
- the fixture has a shape that complements an additional shape of the head-mounted display frame;
- mechanically aligning, with at least one spatially manipulable projector holder, a projected image of at least one projector assembly with the fixed optical coordinate system of the optical sensor to within a second predetermined threshold;
- and
- after mechanically aligning the frame coordinate system and the projected image with the fixed optical coordinate system, securing the at least one projector assembly to the head-mounted display frame.
