What is Interactive Design?

The essence of Interactive Design is designing something that can be interacted with or changed by a wide variety of users. Interactive Design defines the structure and behaviour of a product or system in response to a user. Good interactive design should either assist or initiate interactions with human users and should communicate the functionality and interactivity of the system. Although it is widely regarded as the optimisation of product/system behaviour in response to a user’s interaction, ideally interaction design should go beyond this, to a level where it becomes pleasurable to interact with and enrich the user’s life.
