That doggie in the window is really an interactive projection

Sniff is a really cool interactive projection on a storefront window of an animated dog who follows people walking by on the street. It is able to discern a person’s behavior as friendly or aggressive and then tries to engage them in play as well as being able to form a relationship based on the history of interaction.

The dog is created using the Unity3d Game Engine which renders it in real time as well as dynamically change its behavior based on the video tracking data. An infrared sensitive camera is used to monitor the sidewalk that is illuminated with infrared lights.
