To prepare for the upcoming master courses in Interaction Design, Interaction Design Experiments, and Design for Cooperation, familiarizing yourself with the user-centered design (UCD) process for designing user interfaces and digital services is essential. Among the various names and methodologies for UCD, "design thinking" is the most common, as popularized by d.school.

Additionally, we highly recommend reading "Sketching User Experiences" by Bill Buxton, available as an online resource at the library.

This book takes a unique approach to design and design thinking, emphasizing the need for both designers and their collaborators to better understand these concepts to succeed with new products and systems. Although its primary focus is on design, the book adopts a holistic perspective that speaks to a wide audience including designers, usability specialists, the HCI community, product managers, and business executives. It stresses the importance of balancing back-end concerns like usability and engineering excellence (getting the design right) with up-front investment in sketching and ideation (getting the right design).
