Abstract: A linear actuation mechanism includes a first threaded rod rotatably fixed on a frame, an actuator mechanically coupled to the first threaded rod and configured to cause a rotation thereof, a first nut threaded onto the first threaded rod and attached to a first eyecup configured to hold a first optical element for a headset display, and a rail on the frame configured to support the first eyecup as it moves with the first nut. A headset including a display and two eyepieces supported by at least the first eyecup and the above linear actuation mechanism, and a method for using the linear actuation mechanism to adjust an inter-axial distance between the eyepieces are also provided.
