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.

Take Apart Project


In this project, I decided to take apart my desk "AC" fan. This fan has a water/ice tray that can be used to cool down the air of the fan to give an airconditioning affect. This fan is very simple with a battery and small board to adjust fan speed and intermittent fan mode. It also has a few LED to indicate battery charge and the fan speed/mode. There is also a negative ion generator which does not seem to do much, but apparently can release negative ions that go into the air to attach to positively charged particles like dust, smoke or other allergens that would then dissipate from the air in your room.

This fan simply takes input from the fan speed to turn on and from there you can adjust the mode. Once the button is pressed the signal will be sent to the fan module to start spinning its motor. If the mode is pressed it will then intermittently turn off and on every 10 seconds. Indicator lights will also turn on when each button is pressed to give feedback to the user.
