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.

Week 5

Katie Hendricks & Scott Lui

Current Plan:

We have currently designed our object to be a modular floor panel. The input sensors would be buttons. Shifting away from the DDR idea, we now plan to have the majority of the floor be stationary. There will be many small circular buttons spread evenly across the floor. The output will be light from the buttons and sound.








Materials:

We are in the process of ordering sensors and deciding what our best options are. Here are some of the questions we have been working through in regards to materials with our current resolutions:

-What is the best type of LED Light to create an obvious change from off to on? (Colored LEDs, with clear bulbs, and high mcd)

-What type of sensor should we use to indicate when someone has entered the elevator? (Infrared motion sensor to detect door movement)

-How to we store music in the arduino? (Sound shield)


Not Enough Pins:

The biggest issues we have discovered thus far is the limited number of pins on the arduino since we are attempting have all of our buttons act as unique, individual inputs. We found multiple solutions to this problem on the web. One was to create a grid of wires that would function as a coordinate system to trigger specific lights so less output pins would be required. A second solution would be to purchase a shift register to expand the arduino input pins. The diagram below shows how this connection works. Our last option is to purchase an arduino mega that has 54 digital pins.
