J.J Gibson. I guess I am loving him. I have interests in ecologial issues as systematic approach in designing. I am still so confused that I could not define it in my mine yet. So, I want to study about him and his research further. Prof. Jeff. Could you give me the information more about his ecological theory of perception. And also what is the ecological metaphor in the article? What is the relation between ecological perception and interplay? Could you explain them? 🙂 sorry you guys. I guess it is just my curiosity.
