We're making an outdoor interactive sound installation that will locate five separate sensor interfaces hidden in and around the trees in a public location. In essence, we're surrounding various trees with some great technology to tell (whisper) a story whenever someone passes by.
So what are we trying to do ..... we're aiming to surprise and inspire the passer-by (accidental or otherwise). To engage them in a somewhat heightened awareness of their immediate surroundings and the stories they hold, as if the trees or the nature in their world has a voice … It's also a variation of the old thought experiment "If a tree falls in a forest and no one is around to hear it, does it make a sound?". If no one walks past the tree, it doesn't make a sound ...
Technically there's nothing unusual about the project except that we want the random passer-by to trigger high quality audio from an invisible source, which is something we've never done before. The challenge for us is that the installation is outdoors, not very far from traffic, and needs to be somewhat self-sufficient for the duration (somewhat being the loose operative word here).
All of the technical components will be powered by just one Lithium battery, which needs to remain charged for at least 3 to 4 days, so we can pop in discretely and replace it, or alternatively, use a small solar panel so it's truly self-sufficient, but then it gets harder to make the unit invisible, or at least discrete. Apart from the outdoor speaker (and possibly solar panel) all of the technology will be housed in a small waterproof case and installed in a moist, urban, late autumn, mountain environment for up to three weeks.
