[edit] Basic Idea:
I'm interested in creating two identical hemispherical ultrasound sensor arrays, which can wirelessly transmit distance data between each other and a central computer. The computer will map the control data to sound generation only if a moving object is detected by each of the sensor arrays (which will be physically separated) at the same time. Various sonic parameters will then be affected by the relative values of each sensor. The computer will then output 6 (maybe 8) channel audio to parabolic loudspeakers placed around the sensor site (3 or 4 speakers per site).
I'm ultimately interested in implementing this system along an interior pathway somewhere on campus, such that passers-by could interact with the system without necessarily becoming aware of its existence. Rather, by allowing the chance encounters of spatially separated individuals to drive the work and its perceptual salience, I think an interesting compositional dynamic can be explored.
[edit] Implementation Issues:
- Use two AVR microcontrollers for each of the ultrasound sensor arrays
- Audio Programming in Max/MSP
- Use OSC to interface sensors with computer
Ultrasound Sensor: Which is the best value Ultrasound sensor to use (I would like to use six of them for broader range)? [1] [2]
Wireless: What's the best way to make the two sensor systems and the computer all communicate wirelessly? [3] [4] [5]
Directional Parabolic Loudspeakers: I'm just getting started researching how to best construct these bad boys, any help would be really appreciated.
- These have a f/D ratio of 0.25 and look like they could do the job[6]
- Still need to find some passive speakers to fit 12" cone, easily mounted.
