a novel means and apparatus for a new kind of photography and videography is described . in particular , a wearable camera with a viewfinder suitable for long - term use is introduced . the system , in effect , absorbs and quantifies rays of light and processes this quantigraphic information on a small wearable computer system , then the processed information is re - constituted into light rays emerging to reconstruct the virtual image of objects at nearly the same position in space , or at a coordinate transformed position , as viewed by the wearer of the apparatus . the wearer of the apparatus becomes , after adaptation , an entity that seeks , without conscious thought or effort , an optimal point of vantage and camera orientation . because of the wearer &# 39 ; s ability to constantly see the world through the apparatus , which may also function as an image enhancement device , the apparatus behaves as a true extension of the wearer &# 39 ; s mind and body , giving rise to a new genre of documentary video .
