This short visualization represents Kate Hartman's personal space and heart rate over a two-hour period on the evening of October 23, 2006. Press "START" to begin the visualization.* The green shape, which represents Kate's personal space, changes color when the space becomes uncomfortably small. The red circle in the center represents Kate; it turns red as her heart rate increases.

The visualization program was writting in Processing.

*If the visualization doesn't run when you press "START", try pressing "RESET" and then "START" again. If that doesn't work, please contact us.
