- The interaction design process consists of four basic activities:
identifying needs and establishing requirements, developing
alternative designs that meet those requirements, building
interactive versions of the designs so that they can be
communicated and assessed, and evaluating them.
- Key characteristics of the interaction design process are
explicit incorporation of user involvement, iteration, and
specific usability criteria.
- Before you can begin to establish requirements, you must
understand who the users are and what their goals are in using
- Looking at others’ designs provides useful inspiration and
encourages designers to consider alternative design solutions,
which is key to effective design.
- Usability criteria, technical feasibility, and users’ feedback on
prototypes can all be used to choose among alternatives.
– Prototyping is a useful technique for facilitating user feedback
on designs at all stages.
- Lifecycle models show how development activities relate to one
- The interaction design process is complementary to lifecycle
models from other fields.
