WEEK 1

Key words: Physical computing, Sustainability

In this week lecture, it could make up of two parts, which are physical computing and sustainability. Lecturer told us the Physical Computing is about people interacts through computer via physical interaction. It makes the keyboard, mouse and display behind. For example, touch screen is kind of the physical computing.

I borrowed Physical Computing from library which is lecture recommended. In that book, I found a concept of physical computing. “Physical computing is about creating a conversation between the physical world and the virtual world of the computer” (Sullivan,D & Lgoe, T, pp. xix)
I have done some research about physical computing from internet. A good and clear concept is that “Physical computing is using our own physical inputs and using microcontollers or computers to control outputs.”(http://www.instructables.com/id/SPEI8XLF3ER7V2F/)

So in my word, physical computing is about the communications between physical energy and electrical energy. For easier understand, a vivid chat from Physical Computing is clearly describe how does physical computing work.

Another important word has been talked about is Sustainability in Design. What is sustainability? The guest lecture, Will Odom give some example is about the sustainable design. For example, the energy plugs, energy tree etc. he also show the issue about the old technical devices such as mobile, camera are discard anywhere, which is a serous pollution for the environment.
