Google Glass is changing the way we perceive the world by offering users an augmented reality through wireless technology.

Information including text, video and still images hovers in front of the wearer's eye, as the wearer connects to the internet or issues voice commands.

The technology caused a sensation when it was launched last year, and now artists are using it to expand the way we experience art.

Viewpoint of Billions by David Datuna is an interactive installation that was recently shown at the National Portrait Gallery in Washington.

While 3D viewing has become commonplace, the combination of sculpture, collage, and Google Glass enables visitors to enter the fourth dimension.
