Abstract: A head-mounted display device includes a first set of one or more lenses and a first display configured to provide visual data through the first set of one or more lenses. The head-mounted display device further includes a first stepper motor mechanically coupled to the first display, and the first stepper motor is configured to move the first display along a first axis by rotating a rotatable component of the first stepper motor. The head-mounted display device further includes a first electronic controller configured to (i) determine a first position of the first display, (ii) receive information identifying a second position of the first display, and (iii) generate one or more electrical signals that cause the first stepper motor to move the first display from the first position to the second position along the first axis.

Abstract: A head mounted display (HMD) includes a set of one or more lenses defining an optical axis, a display configured to project light through the set of the one or more lenses, a voice coil actuator coupled with the display and configured to move the display along the optical axis, and a first guide that is separate from the first voice coil actuator and coupled with the first display to guide the movement of the first display. The HMD additionally includes a set of one or more position sensors configured to determine a position of the display long the optical axis and an electronic controller configured to receive information identifying a reference position of the display along the optical axis and generate one or more electrical signals for initiating a movement of the first display toward the first reference point along the optical axis.
