This is my first official course, Introduction of Computational Design, offered in the Graduate School of Architecture of National Chiao Tung University. This course is mainly coordinated by Prof. June-Hao Hou and cooperated with Prof. Yen-Liang Aw Wu. I was introducing the implementation of Tangible Interaction (Arduino), while Yen-Liang was focusing on the programming of Graphical Interaction (Processing). The purpose of this course is to replace the conventional design thinking of students with the computational ways.
