Interaction design is usually associated with designing / improving usability and defined by ISO 9241-11; ”Extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use”. It is therefore important to have a good utility in view of being able to design a product that will satisfy the customer's needs. This means that one must strive to create an efficient system that can be used in different environments while not being demanding to use. Typical measures to measure usability:
- How well the test users perform at solving specified test tasks, measured in proportion of solved data, how long it took, or how many errors were made;
- How flexible the design of the system is, measured in proportion of test users from a heterogeneous group who managed to perform the specified test tasks;
- How easy the system is to learn, expression in proportion of solved tasks, presentation times and number of errors over time, how well the test users remember what they learned, how often they have to use help functions or ask for advice;
- What the test users think of the system, measured in their own estimates of, for example, the system's helpfulness and efficiency.
A clear definition of the meaning of the interaction design is difficult because the concept is extremely extensive but it is possible to explain interaction design as the process arranged within limited resource frameworks to create, shape and determine the utility-oriented properties (structural, functional, ethical and aesthetic) of a digital artifact. for one or more clients.
