A Framework for Ecological Interface Design (EID)
The growing attention to and interest in interface design has been fueled by advances in both hardware (particularly graphics) and software. This technology provides opportunities for design innovation that make Shneiderman’s lofty goals to make “the world a little warmer, wiser, safer, and more compassionate” far more realistic than they were a generation ago. To make this point explicit, consider the hardware and software of the ¤rst interactive interfaces. The teletype interface (see Figure 6.1) was essentially a glori¤ed typewriter that included a keyboard for input and a roll of paper for output. The user typed in alpha-numeric input one line at a time via a command line interface; the computer typed out lines of alphanumeric symbols.
