As computing becomes more ubiquitous in our objects, designers need to be more aware of how to design meaningful interactions into electronically enhanced objects. At the University of Washington, a class of junior Interaction Design majors is exploring this question. These pages chronicle their efforts.

This past week has been exciting as we have made a significant amount of progress. Our code is now fully functional and our final bottle model is nearing completion. The transition from paper cups to a water bottle required a few slight code alterations, as the thicker plastic walls made the capacitive sensors less sensitive to changes in water level.

This video shows our code working on a paper cup. The LED is set to blink every 10 seconds if water is not consumed (it will probably be 1 hour in our final model). The LED turns off/timer resets if the water level goes down.

Some process photos of water bottle construction:
