The Interactive Mesh Idea

I finally got it to work the way I envisioned it.

I have written previously about using a mesh and projecting images my class can interact with in real time.  We have interacted with projected stories and shown rocket launches on the mesh to add a surreal layer of viewing.

But last week, we kicked it up a notch by using the mesh for an interactive live performance.

We performed the song, "Walking in the Air," by Howard Blake.  We had three performance elements:
  • Music/sound/singing.  The song is a dreamy one about walking through the sky.  My class and another grade 2 class sang the song. 
You can make out the two-class choir silhouetted on the risers on the left.
  • Painting/visual.  While we sang, one of the 7 "painters" took turns painting beautiful splattery colours onto the interactive mesh from behind it using the IR pen.  The painters painted in real time (using jacksonpollock.org)  creating a surreal sunset on the mesh.  Because the projector was angled so sharply upwards, the painting did not just appear on the mesh, but also enlarged on the gym wall up to the ceiling. 
Here is a picture of me explaining the painting while a student
who you can slightly see behind the mesh,
paints on the mesh which transfers to the wall behind. 
You can also see the same small image on the laptop screen on the cart.
  • Dance/movement.  As the singers sang and the painters painted, dancers danced slowly and flowingly in front of the mesh.  Because the dancers were in front of the projector, their shadows were cast onto the mesh and enlarged on the wall behind the mesh.

Putting it all together, it gave the dreamy impression that the we were indeed walking in the air.
