DUE: THURS SEPT 29th @ 6:30 pm


With the help of a multimeter borrowed from the sensor lab, try to find several conductive/semi-conductive materials and/or objects. Trash cans, food vendors, your body, stationery, and parks are good places to start looking…
Analyze and document the physical, electrical, structural, perceptual and aesthetic properties for each item found.


Think of different ways you could design a binary interface that utilizes a physical electric switch (i.e. a transistor) as its sole input.
This interface must use at least one of the conductive materials/objects that you discovered in your research.
Try to imagine a scenario for your binary interface that is not straightforward or too functional.
Explain the spatial, temporal and social contexts of your scenario.
Describe with a storyboard how the interaction (human -> binary interface) would work.


Build the interface (on a bread board is fine).
Bring it to class for a live demo.
Ensure that it results in a simple electric action, i.e. turn on an led.
Do not use a microcontroller.
