No TL;DR found
Abstract
Usability and user experience (UX) are important concepts in the design and evaluation of products or systems intended for human use. This chapter introduces the fundamentals of design for usability and UX, focusing on the application of science, art, and craft to their principled design. It reviews the major methods of usability assessment, focusing on usability testing. The concept of UX casts a broad net over all of the experiential aspects of use, primarily subjective experience. User-centered design and design thinking are methods used to produce initial designs, after which they typically use iteration for design improvement. Service design is a relatively new area of design for usability and UX practitioners. The fundamental goal of usability testing is to help developers produce more usable products. The primary activity in diagnostic problem discovery tests is the discovery, prioritization, and resolution of usability problems.
