Zusammenfassung, Abstract
This chapter gives a general overview of past, current and future visual displays, their technical basis and resulting characteristics relevant to human-computer interaction. In this context, computers may be understood as stationary desktop systems as well as mobile devices like notebooks, personal digital assistants (PDAs), and other pocket or handheld devices. Together with the general development of human-computer interaction, the technology of visual displays has quickly evolved over the last decades. The majority of visual displays in human-computer interaction is based on the variation of light (e.g. indicator lights signaling power on or the main visual display), but there are still some visual indicators on common computers that rely on the displacement of a physical entity. Examples are the write protect tab on a 3.5" floppy disk, the eject button on the floppy disk drive, or latches on notebook computers. Displays based on the displacement of a physical entity might have the advantage that they can be perceived by touch and therefore do not rely solely on the human visual system to convey their message. But the amount of information that can be displayed is restricted. Therefore all displays discussed further on in this chapter are based on visual light, i.e. electromagnetic radiation with a wavelength between about 380 nm and 780 nm. Some newer developments in human-computer interaction (e.g. Virtual Reality and Augmented Reality) require visual displays with characteristics very different from today’s found on standard PCs. On the other hand, technical devices with formerly restricted interaction possibilities are becoming more "intelligent". Hence the user interaction is more diverse and one way of accomplishing this is by implementing visual interfaces with greater spatial resolution. Many of these devices show a similar evolution of the visual display as the computer did: from simple lamps to graphical displays.
