Elevator Intervention

Elevator Intervention is a physical computing device that introduces game mechanics to encourage members of the Interaction Design department to take the stairs, rather than the elevator, when traveling between classes on the sixth and eleventh floors of campus building 209 East 23 Street.

A user approaches the bank of elevators on the sixth floor landing of the Interaction Design department and stands in front of the elevator console with the intent of taking the elevator to the eleventh floor. (Fig. 1) She is arrested by a large, wall-projected display of the number times students have taken the stairs plus calories burned. After consideration, she decides whether to ride the elevator by retrieving the elevator car (opt-out), or, proceed toward the stairwell to take the stairs (opt-in).

When entering the stairwell, she steps on a purpose-built force sensor placed at the foot of the doorway. (Fig. 2) The force sensor detects how much pressure is applied to its sensing area and communicates this amount to the system controller. (Fig. 3) If the amount of pressure is above a certain threshold (the typical amount of force a person will exert when placing a foot on the ground while walking), the system updates the wall-projected display.
