hey,

i'm working at the moment on an computer vision-based augmented tabletop interface to what is shaping up to be a kind of live map of a naturalistic setting.

our aim with this project is to remove any perception of technology from it; we want to give users the feeling that they're some kind of benevolent god-like being perched over a real landscape. using their hands they can interact with this landscape.

the vision part and the rendering are taken care of; it needs sound. i thought what might be neat is for the users' hands to act as giant wind paddles - so as they moved them over the landscape, they'd be able to hear the results of their movement as some kind of vaguely realistic wind noise.

any pointers on where i might start with this? i've been looking at physical modelling but most of the documents out there seem to deal with modelling acoustic instruments rather than natural acoustic phenomena; perhaps physical modelling might be overkill for what will probably end up being basically a series of noise filters..?
