- What is physical interaction?
- What does the user do? Observing people using interactive devices
- Descriptions. pictures, videos
Fantasy Device – As a class, we’ll make a list of fantasy devices; things that don’t exist, but that we wish did. For today, we’ll ignore technical feasibility and concentrate on how you’d operate these devices if they did exist. You’ll be divided into groups of 3. Pick a fantasy device from the list. Design a control interface for this device and demonstrate it in class.
Think about what a person has to see, hear, touch, etc. while operating the device. Think about what cues they need to understand the interface. Think about what parts of their body they need to have free, what gestures are best for triggering the device’s behaviors, and so forth. Build a mockup of the controls from anything you can find nearby. At the end of class, one or two of you will act out the use of the device using your mockup while the third person narrates.
Assignments for next class
By now, you should have ordered the basic parts and tools that you’ll need for class. If not, do so ASAP.
Set up your Physical Computing Comp blog and e-mail the URL to your instructor.
Read or view the following material and try the labs below as soon as you have parts. Come to next class with questions:

- Electronic Tools
- Electrical Measurements
- Ohm’s Law Part 1 and Part 2
- Current for an LED
- LEDs Behaving Badly
- Schematic Diagrams
Do the labs below. Blog your progress and questions, and come to class next week with questions. We’ll discuss together.
Readings For Next Class
The following readings provide some context for thinking about physical interaction design. You won’t be quizzed on whether you’ve read these, but your instructor may refer to these ideas in future class discussions.
