An Interactive 3D Projection Room developed with projection mapping and leap motion. In the event space wall, a 3D room with grids was projected through a projector and divided into 3 separate section using wall corners. A leap motion device was place in front of the wall. Users could move the floating television sets in the wall in a looping scroll through hand gestures. Users could also point at the middle section of the wall to select out of the three sections which would open another three options each with pre rendered video thumbnails. Users can scroll further or point at the middle section to play the video in the television set or point backwards to go back to the previous menu.
