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.
