Intuitively, this is the final article in the series. Part I, II, and III and IV all cover different principles and this article wraps them all up. They would be worth reviewing to get the full context of the article.
Design principles from Don Norman’s Design of Everyday Things provide a fantastic overview of the fundamental principles in industrial design. Those same principles apply to any type of design and are especially relevant in digital and mobile design. But like many academic principles, implementing those principles in a practical sense is often difficult. What I hope to learn with these articles is some practical ways of implementing that within Android. Feel free to correct me when I’m wrong, I’m learning this too.
