I’ve been looking at different ways to record a persons breath. My first iteration of a computing fractal drawing was using the microphone to allow the air blown over the microphone to convert this into a range between 0 and 1. I feel there is a barrier for the user to understand the way there breath effects the drawn lines, as in reality it is just sound. I’ve been looking at how breathalysers and other breath monitors allow for a a persons oyxgen and content can be recorded.

There could be some interesting results from asking people to blow into a breathalyser type system, maybe people would refuse or feel a sense of violation, suspecting  I was saving there data in some ways. Or it could be an interesting side question to be discussed around the work. Another alternive is to continue using the microphone input but create a model of a more breathalyser style unit to encasing it to create the illusion of a more medical device.
