Ongoing developments in information technology have led to an increasing demand for 3-D displays. Indeed, a broad range of fairly mature 3-D equipment is already on the market. The available systems, however, suffer from the drawback that users have to wear special devices to separate the left eye's and right eye's images. Such 'aided viewing' systems have been firmly established in many professional applications. Yet further expansion to other fields will require 'free viewing' systems with improved viewing comfort and closer adaptation to the mechanisms of binocular vision. The respective technologies are still under development. This article reviews the state-of-the-art of both aided viewing and free viewing systems.
