I watched the video.
Is the difference between us that I view immersion more in terms of the capacity of the listener while you seem to view the listener more as a passive factor, with technology facilitating immersion? Or perhaps we define immersion differently. I don’t need to have my walls "painted with sound" in order to experience what I describe as immersion. This sounds like a remedy for people’s senses having become dulled.
If one is esthetically sensitive by nature, as I am, and has experienced making music, as I have, there is no need for any "added stimulation". I’m reminded of a current local Van Gogh exhibit I read about, which incorporates blowing up and projecting his paintings onto museum walls, so people can "walk through them". As a life-long art lover and someone who's been involved in drawing, printmaking and photography, this strikes me as very odd -- that people can only perceive and appreciate art when it’s turned into an IMAX experience.
