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 Labs|Radboud Immersive Virtual Environment Research labs]].

HTC Vive

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[1]. HMDs are most often used for virtual reality, for instance in the Radboud Immersive Virtual Environment Research labs.


Specifications

We currently offer the following types of head-mounted display in our research labs. For a full comparison of past and present HMDs, as well as other headsets on the market, see Comparison.
