• Observation (In class)

Pick a piece of interactive technology in public, used by multiple people. Describe the context in which it's being used. Watch people use it, preferably without them knowing they're being observed. Take notes on how they use it, what they do differently, what appear to be the difficulties, what appear to be the easiest parts. Record what takes the longest, what takes the least amount of time, and how long the whole transaction takes.

• After reading Chris Crawford's definition, how would you define physical interaction? What makes for good physical interaction? Can you name some examples of digital technology that are not interactive?

Introduction to Physical Computing

Spring 2012

Link to printable syllabus

Physical Computing is an approach to learning how humans communicate through computers that starts by considering how humans express themselves physically. In this course, we take the human body as a given, and attempt to design computing applications within the limits of its expression.

To realize this goal, you'll learn how a computer converts the changes in energy given off by our bodies (in the form of sound, light, motion, and other forms) into changing electronic signals that it can read interpret. You'll learn about the sensors that do this, and about very simple computers called microcontrollers that read sensors and convert their output into data. Finally, you'll learn how microcontrollers communicate with other computers.

Physical computing takes a hands-on approach, which means that you spend a lot of time building circuits, soldering, writing programs, building structures to hold sensors and controls, and figuring out how best to make all of these things relate to a person's expression.

Some time in weeks 1 - 3: Attend a tool safety session in the shop

For each week, you'll find:

• Concepts we'll discuss in class. Course notes are linked so you can read them before class, to know what we're talking about.
• Lab exercises that illustrate the concepts. You're not required to show your lab work in class, but do them each week to learn, and come in with questions if you have any. If you did something you're proud of, feel free to bring it in, though this is optional.
• Production assignments larger assignments which have scheduled times you'll be expected to show them in class.
• Reading to be read in the week they're assigned. Will come up in discussion the week after, usually.
• Blog assignments Writing the week when it's assigned. Will come up in class from time to time. Read each other's stuff too.
• Due dates for production assignments
