Workshop - spaces and perception

Our space: the stairways between ground floor and first floor.

Projecting on to surfaces with different angles 

Adjusting the picture to make the pattern look similar on the two walls.

Our concept is that a person who is walking down the stairs is getting a feeling of spring. We use an Arduino with ultra sound to sense if somebody is passing the stairs to trigger the animation. The arduino communicates with the processing code that lets the movie start to play. The animation also contains sound and a bee that is starting to fly around on the wall as a person passes and then in the end explodes somehow.

It was really hard to figure out how the perspective had to be to make a good viewer experience. We projected a grid on the wall. This picture is taken from the point of the projector. The perspective is not distorted. 

This picture is the same projection, but seen from the third step in the stairs - where we want the people passing by to see the projection good and not distorted on the left wall.
