A head-mounted display (HMD), is a display device worn on the head or as part of a helmet, glasses or visor, that has a small display optic in front of one or each eye<ref>https://en.wikipedia.org/wiki/Head-mounted_display</ref>. HMDs are most often used for virtual reality, for instance in the [[RIVER Lab]].
