2 Goals and principles of user-centred design

In Section 1, we discussed key aspects of the interaction design process, including the importance of establishing clear usability and user experience goals. In this section we go into more detail about what we actually mean by usability goals and user experience goals, and how we can assess whether a product can be considered to have achieved these goals. We also introduce design principles that can help to aid a designer’s thinking when they are designing interactive products.
