Psychology prof's creation displayed on Berlin building
An electronic display of two 12-meter-high, point-light "walkers" developed in Psychology professor Niko Troje's Queen's laboratory is prominently featured on the front of a new science centre in downtown Berlin.
Dr. Troje attended the opening of the Otto Bock Science Center of Medical Technology recently, as a guest of Germany's federal minister of External Affairs Frank-Walter Steinmeier and Berlin mayor Klaus Wowereit. Located between Potsdamer Platz and the Brandenburg Gate, the new building is in a direct line of sight from the glass dome on top of the Berlin Reichstag, a popular tourist destination. A sign encourages visitors to "Discover what moves us."
In his Biomotion Laboratory at Queen's, Dr. Troje and his students use high-speed cameras to track small reflective markers attached to the central joints of a person's body. When the subject moves, these seemingly unstructured white marker dots become organized into meaningful images, from which observers can determine the gender, body build, emotional state, and other attributes.
