Shadow Catching Prototype

Concept

I decided to design an interactive space that would react to people's shadows as they walked into the lobby. On our tour we observed that the lobby was a dead space and not somewhere people enjoyed staying in. Also, when you entered it was unclear where you needed to go, as they had removed the traditional check-in counter and I wanted to help guide new guests correctly.

Technical Details

This was a 'skills upgrade' workshop, so inspired by the shadow installations by the like of Mine-Control I decided to do something similar myself. Detecting shadows, and then reacting to them is very processing intensive so I needed to use something faster than Flash or Processing which I'm used to. The Rockwell Group use openFrameworks a huge amount so I decided this would be a good opportunity to try learn a new skill.

After a few days battling the sharp learning curve of C++ and using XCode, I managed to get a basic demo up and running. In the future, I hope to build on this experiment further.
