Inter-pupillary distance adjustment mechanisms for head-mounted displays

Abstract

An inter-pupillary distance (IPD) adjustment mechanism for a head-mounted display (HMD) is disclosed. The IPD adjustment mechanism is coupled to a structural plate of the HMD and to an eyecup for each eye that includes a lens and display assemblies. The IPD adjustment mechanism includes an arm for each optical assembly, and a gear that interfaces with the arms. In one embodiment, each arm is a rack gear that interfaces with a pinion gear. The eyecups are each mounted on one or more rails that allow for the eyecups to adjust a distance between the eyecups along a single dimension. Accordingly, movement of the gear causes both eyecups to move either away from or towards each other. In some embodiments, the IPD adjustment mechanisms is driven by a motor. In some embodiments, the IPD adjustment mechanism is manually controlled by the user.
