Time: 2010

Type: School

Class: Telling Stories with Data, Sensors & Humans

Instructor: Nick Bilton

Role: Designer, developer. Worked with Michael Edgcumbe


As final project for class, Michael and I decided to figure out one unanswered question of ITP, which elevator is more frequently used. We collected the elevators usage data first. Then visualized the data in real time animation via Processing.

To collect data, we used two ultrasonic sensors adhered above the gate of each elevator. Via serial communication, data is sent back to a logging device powered by Arduino, which saves data in a flash card. You can see the setup here.

To visualize, a Processing program draws an oval shape for every 2 minute along on the timeline. The height of the oval is determined by how many people coming in/out of the elevators in that time period.
