Document Summary
Interaction design is about constructing usable interactive artefacts: Let"s first see what is not usable. Elevator controls and labels on the bottom row all look the same, so it is easy to push a label by mistake instead of a control button. People do not make same mistake for the labels and buttons on the. Shapes, colors (foreground and background), textures, groupings, placement, icons, noise signals, lights. If we don"t have justification for decisions we just do random stuff. Random stuff is not design let alone good design. Need to push button first to activate reader. And we normally insert bill first before making selection. Design concern: how to minimize users effort to understand how it works. A systematic way to go about developing interactive products and interfaces. Unsystematic: rely on your intuition, talent and good luck! Systematic: follow defined processes and principles, established by decades of development. Understanding of the goals that need to be fulfilled.
