Abstract

This novel Head Mounted Display (HMD) has a removable communications unit which can be interchangeably worn on the right or left side of the user. Thus, users having a hearing deficiency in one ear can use the opposite ear. Also, the HMD has a fully adjustable eyepiece which can be swung out of the way when not in use or can be used adjacent either eye. An important feature of this invention is an eye guard which prevents the eyepiece from striking the user'"'"'s eye or face portion.
