Question:

1. I think I would be interested in building a machine that can deliver things and people in a short time. I think the use of actuators are the foundation of interactive design. It can visualize the output of certain devices and also identifying the people they are interacting with. The process of creating an interactive devices with logical coding and different components is really impressive. This process inspired me to understand the organism of the movements of our body and deep essence of “interaction”, which can be considered as one of the most important parts of human civilization.
2. One project that impresses me is “The Table” created by Raffaello D’Andrea, Max Dean and Matt Donavan in 2001. Since the table will chase the target people once it identified the people as its viewer, that should be a motor and a distance sensor. I think this project is good because the interaction is complicated and creative. The table actually recognized people and try to appeal to people’s incentive to interact with it. I think the major distinction between this project and the drawing machine I did in the recitation session is the degree of human intervention. This table interacted with human by its own while the drawing machine still needs some information input by human beings.
