The aim of Expressive Identity is to use an interactive exhibit to express identity through audience movement and expression.

By playing repetitive looping footage of people in movement, unique characteristics will stand out. When people's movement are compared to each other side by side, differences in personality becomes clear.

The interactive exhibit uses a webcam to film people infront of a large screen. When there is a person infront of the screen five frames of their movement are recorded and added to the screen. The screen has a grid of 20 smaller screens which continuously loop the captured footage. The newest footage replaces the oldest footage and keeps the screen busy with activity.

The exhibit for Expressive Identity uses facial tracking to know when there is anyone infront of the camera. By only capturing footage when people are infront of the camera, a broader range of people can be shown on the screen at once.
