1. A near-to-eye (NR2I) head-mounted display (HMD) system comprising:
a frame configured to encompass a head of a user;
a first temple arm attached at a first end to a first side of the frame and configured to project forward along a first side of the head of the user;
a second temple arm attached at a first end to a second side of the frame opposite the first side of the frame and configured to project forward along a second side of the head of the user opposite to the first side of the head of the user; and
a display assembly attached at a first location to a second distal end of the first temple arm with a first universal joint and at a second location to a second distal end of the second temple arm with a second universal joint; wherein
each of the first universal joint and the second universal joint provide for motion in two degrees of freedom with respect to the head of the user;
a first degree of freedom of the two degrees of freedom is rotational motion within a sagittal plane of the user;
the second degree of freedom of the two degrees of freedom is rotational motion within an axial plane of the user;
each of the first universal joint and the second universal joint are located proximal a first temple and a second temple of the user respectively when worn by the user;
the first temple arm is extensible and comprises a first thumbwheel and a first track wherein the first thumbwheel interacts with the first track to translate the first universal joint at the second distal end of the first temple arm relative to the first end of the first temple arm;
the second temple arm is extensible and comprises a second thumbwheel and a second track wherein the second thumbwheel interacts with the second track to translate the second universal joint at the second distal end of the second temple arm relative to the first end of the second temple arm; and
an eye-relief of the user with respect to the display assembly can be independently set for each eye of the user.
