OHMDs are used in [[augmented reality]] (AR). Unlike [[head-mounted display#Virtual Reality HMDs|virtual reality HMDs]] that obscure our vision of the real world, OHMDs allow us to see our surroundings while streaming data and image overlays in front of our eyes. | ||

[[Vuzix]] is a provider of OST-HMDs. | |||
