1) Interaction design education requires learning about people through anthropology, ethnography, observation and participation. It also involves learning about information structures, activities, processes, and people's perception/cognition.
2) Early design education focuses on creativity, criticism of design work, and developing craft skills. Interaction design education builds on this with additional topics like information architecture, activity flow, and understanding technology's impact on complexity.
3) Becoming an interaction designer is a long-term process that requires passion, mentors, exploring multiple media and skills beyond traditional design like rapid prototyping, physical computing, and filmmaking. Practice, case studies, and having the right learning environment are also important.
