I had no concept of what physical computing is prior to this semester. However, now I tend to find a lot of physical computing examples in my daily life. Even with my limited knowledge, I still try to figure out how would I make the dazzling lights show or big display screen with shiny letters. I also really like the idea of using technology to read human behaviours, analyze it and give feedback to hopefully improve the user experience. I am glad I have taken those IM classes this semester because I feel that my skills in programming now exists beyond just the screen of my computer but also in the real world. I am very proud that people can interact with some projects I have designed. The interaction between arts and technology truly makes physical computing interesting.
