1. A virtual or augmented reality headset, comprising:

  • a frame including opposing arm members and a bridge portion 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 coupled to both of the pair of virtual or augmented reality eyepieces and operable to simultaneously move the pair of virtual or augmented reality eyepieces to adjust the interpupillary distance, the adjustment mechanism including a linear actuator physically coupled to the pair of virtual or augmented reality eyepieces by a plurality of links which are arranged such that movement of the linear actuator in a first direction causes the plurality of links 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 direction opposite the first direction causes the plurality of links to decrease the interpupillary distance between the optical centers of the pair of virtual or augmented reality eyepieces;

    wherein the frame includes at least two linear rails on each of the opposing sides of the frame vertically offset from each other to guide a respective one of the virtual or augmented reality eyepieces, andwherein, for each of the opposing sides of the frame, the at least two linear rails and the arm member form a fork structure.
