1. A virtual or augmented reality headset, comprising:
- a frame including opposing arm members and a bridge positioned intermediate the opposing arm members;
a pair of virtual or augmented reality eyepieces each having an optical center, the pair of virtual or augmented reality eyepieces movably coupled to the frame to enable adjustment of an interpupillary distance between the optical centers; and
an adjustment mechanism configured to simultaneously move the pair of virtual or augmented reality eyepieces to adjust the interpupillary distance between the optical centers of the virtual or augmented reality eyepieces along a first axis, the adjustment mechanism comprising;
a linear actuator having a link driving portion that is configured to translate linearly back and forth along a second axis perpendicular to the first axis, the link driving portion of the linear actuator being physically coupled to a first end of a first link and a first end of a second link to selectively move a connection point of the first end of the first link and a connection point of the first end of the second link together in a straight line in a same direction, a second end of the first link movably coupled to a first rail and a second end of the second link movably coupled to a second rail such that movement of the link driving portion of the linear actuator in a first linear direction along the second axis causes the first and second links and first and second rails to increase the interpupillary distance between the optical centers of the pair of virtual or augmented reality eyepieces and movement of the linear actuator in a second linear direction along the second axis that is opposite the first linear direction causes the plurality of links to decrease the interpupillary distance between the optical centers of the pair of virtual or augmented reality eyepieces.

Abstract
A virtual or augmented reality headset is provided having a frame, a pair of virtual or augmented reality eyepieces, and an interpupillary distance adjustment mechanism. The frame includes opposing arm members and a bridge positioned intermediate the opposing arm members. The adjustment mechanism is coupled to the virtual or augmented reality eyepieces and operable to simultaneously move the eyepieces to adjust the interpupillary distance of the eyepieces.
