Research on Biofeedback practices:

David Rosenboom defines Biofeedback in his book ‘Biofeedback and the arts: results of early experiments’ (1975) as the presentation to an organism through “sensory input channel  of information about the state and/or course of change of a biological process in that organism” to find some performance control over the process or for “internal exploration and self-awareness”

I had a look into Paul Granions work which is very interesting then an idea popped into my head. I got a VR headset (phone) for Christmas which costs $15 online, maybe I could turn it into a Paul Granion-esque device.

So I will need to have at least two sensors to collect data from the user then can convert it into something else using Arduino devices. I would like to create an experience inside the headset which closes the user off from the outside world and into the rhythm of there heart beat.
