All kinds of modern information systems (e.g., big data analytics systems, decision support systems, transaction processing systems, etc.) involve humans (users), computers, and their constant interactions. Accordingly, studying human-computer interactions is essential for enhancing the ultimate utilization of any kinds of information systems. This course aims to enrich students’ knowledge and practical skills for the design of user interfaces for general business systems, mobile apps, and e-Commerce Websites. In particular, students will be guided to explore the intersection between cognitive psychology and information systems for a disciplined and systematic way of designing, prototyping, and evaluating practical user interfaces.
