Interaction Design aims to optimise people's interactions with technology. Unlike twenty years ago, when computers were the preserve of professionals or enthusiasts, technology now needs to be designed as part of everyday culture. It must be successfully and gracefully integrated into real life. It must possess emotive as well as functional qualities. Interaction Design strives to design interactions that make work effective, safer and more proficient. It supports evolved forms of communication, expression and creativity. It augments learning environments and provides exciting new forms of entertainment.
Interaction Design merges the theory and technique of traditional design with a host of other disciplines to create a combination of procedures and methods singular to the field. Interaction Design understands that the design of a computer-based system or device, must not only focus on the way it looks and functions but also on the way it facilitates interactions with a human. Essentially Interaction Design concerns itself with the way the system or device behaves in response to a person using it.
