Say goodbye to the mouse and hello to augmented reality, voice recognition, and geospatial tracking.
Computer scientists from around the world will gather in Boston this week at Computer-Human Interaction 2009 to discuss the latest developments in computer interfaces. To coincide with the event, we present a roundup of the coolest computer interfaces past, present, and future.The granddaddy of all computer interfaces is the command line, which surfaced as a more effective way to control computers in the 1950s. Previously, commands had to be fed into a computer in batches, usually via a punch card or paper tape. Teletype machines, which were normally used for telegraph transmissions, were adapted as a way for users to change commands partway through a process, and receive feedback from a computer in near real time.
Video display units allowed command line information to be displayed more rapidly. The VT100, a video terminal released by Digital Equipment Corporation (DEC) in 1978, is still emulated by some modern operating systems as a way to display the command line.
Graphical user interfaces, which emerged commercially in the 1980s, made computers much easier for most people to use, but the command line still offers substantial power and flexibility for expert users.
