Interaction Design
(Interaction Design & Interface Development)Interaction Design is the discipline of defining the behavior of products and systems that a user can interact with.
Interaction design aims to minimize the learning curve and to increase accuracy and efficiency of a task without diminishing usefulness. The objective is to reduce frustration and increase user productivity and satisfaction.
Interaction design attempts to improve the usability and experience of the product, by first researching and understanding certain users' needs and then designing to meet and exceed them.
Interaction design is a systematic and iterative process for designing highly interactive user interfaces. Methodology includes research and discovery techniques such as requirements analysis, stakeholder analysis, task analysis, as well as prototyping, inspection and evaluation methods.Interaction designers work in many areas, including software interfaces, (business) information systems, internet, physical products, environments, services, and systems which may combine many of these.
Each area requires its own skills and approaches, but there are aspects of interaction design common to all.
