I’ve spend some time trying to experience and understand the concept of ASMR. I really see potential in it and love the mediated experience. I’ve had tingling and even momentarily euphoria! It stimulate sensations of actual touch and visual enjoyment.
One of my favorite ASMR practitioners is Ally of ASMRrequests. She explains her concern about the experience of being touched in a mediated way through the microphones: http://youtu.be/k-VVYMsBFXM?t=16m39s.
I really love this new kind of experience design problem.
