A display system represents the point at which the user meets technology: the man-machine interface. It can take many forms: from TV or laptop screen to the video recorder display, the telephone menu, a VR headpiece; to a car dashboard, aeroplane cockpit or HDTV display, Applications are wide-ranging and the developments are moving forward rapidly. This work looks at display technology from a pragmatic perspective, with a view to defining its best potential. Contributions focus on the design principles and practical requirements of displays in a range of applications, the performance and optimization of displays, assessing what today's techniques can offer and more. The overall theme is practical, with each contributor presenting their view on a key aspect of this rapidly developing field. Focuses on practical exploitation of display technology; reflects state-of-the-art developments; and applications covered have cross-disciplinary potential.
