Abstract
A head-mounted display includes a varifocal actuation block and an optics block coupled to the varifocal actuation block. An anti-creep system located in the varifocal actuation block includes a plurality of anti-creep mechanisms that are configured to prevent bearing ball creep associated with bearing balls in the varifocal actuation block. The bearing balls are used to move a movable carriage that is coupled to a fixed carriage in the head-mounted display via the anti-creep mechanism. The anti-creep mechanisms prevent bearing ball creep associated with the bearing balls from occurring in the varifocal actuation block by limiting the movement in an angular direction of the bearing balls that are used to move the movable carriage in a first direction in the head-mounted display.
