What is interaction design?  By interaction design, we mean designing interactive products to support the way people communicate and interact in their everyday and working lives. Basically, creating user experience that enhance and augment the way people work, communicate, and interact.  The focus of interaction design is very much concerned with practice. It is not devoted to a particular way of doing design, but is more eclectic, promoting the use of a range of methods, techniques, and frameworks.  Interaction design is fundamental to all disciplines, fields and approaches that are concerned with researching and designing computer-based systems for people.  Most interaction design is done by multidisciplinary teams, where the skill sets of various disciplines are drawn upon. Who is involved in interaction design?  Engineers  Designers  Programmers  Psychologists  Anthropologists  Sociologists  Artists Toy Makers The point is to optimise the users interaction  Make choices based on the understanding of the user;  Take into account what people are good and bad at;  Consider what would help people with the way they are currently doing things;  Think through what might provide a quality user experience;  Listen what the people involved in the design want;  Use tried and tested user-based techniques during the design process. Goals of interactive design  To reduce the negative aspects (frustration, annoyance) of the user experience  To enhance the positive aspects (enjoyment, engagement) of the user experience  To develop interactive products which are easy, effective and pleasurable from the users perspective Process of Interaction Design  Establishing requirements  Designing alternatives  Prototyping  Evaluating Good interaction design  Aesthetically pleasing  Easy to learn  Effective to use  Simple to use  They provide an enjoyable user experience Bad interactive design  Frustrating  Confusing  Inefficient  Difficult to use Four basic activities involved in the process of interaction  Identifying needs and establishing requirements for the user experience  Developing alternative designs that meet those requirements  Building interactive versions of the design so that they can be communicated and assessed  Evaluating what is being built throughout the process and the user experience it offers
