Editing Head-up display (section)

== Further development and experimental uses ==
HUDs have been proposed or are being experimentally developed for a number of other applications. In military settings, a HUD can be used to overlay tactical information such as the output of a laser [[Rangefinding telemeter|rangefinder]] or squadmate locations to [[infantry]]men. A prototype HUD has also been developed that displays information on the inside of a swimmer's goggles or [[Diving mask#Types of diving mask|of a scuba diver's mask]].<ref>{{cite web|author= Clothier, Julie |url=http://edition.cnn.com/2005/TECH/06/23/spark.goggle/index.html?section=cnn_tech |title=Clothier, Julie.

A HUD product developed in 2012 could perform real-time language translation.<ref>Borghino, Dario (29 July 2012).

The [[Google Glass]] was another early product.
