Principles for Human-Centred Design of IR Interfaces

Since the ‘80s, Human-Computer Interaction (HCI) researchers have performed a lot of work to identify principles, techniques, and methodologies that can support design, evaluation and implementation of interactive systems that fulfill needs and expectations of their users. This chapter discusses con- cepts, such as usability and user experience, which are of great importance for the success of interactive systems, illustrating how Human-Centred Design is fundamental to create successful user interfaces. Principles proposed by the HCI community to support interface design are presented, analyzing the princi- ples that have a major impact on IR interfaces.
