It’s almost like saying… at least after reading your piece and coming back to this point… that we are probably looking at a term or goal of participant experience design as the perspective and practice.
What we seem to want, as designers and maintainers of platforms, are people who use these elements as part of their experience towards being human. If you will, we create these tools, methods, platforms, and ecosystems as layers of a canvas. Our empathy towards their humanity enables us to make those layers known and value-given, so that by interacting with them, a person feels better connected to their own humanity.
Participant experience [design] feels almost like the right way to term this.
