The physical embodiment of existech grew out of an interest in expressive photography, the tools of which I re-situated as extensions of my mind and body. WearComp has three characteristics I call Ephemeral, Existential, and Eudaemonic. It's not something I pull out of my pocket, turn on, boot up, and then finally interact with. The apparatus is situated in my own personal space, in the sense that I regard it as part of me, and others do as well.
Clothing is much more eudaemonic, and is thus a more natural place to put such an apparatus.
Ordinary cloth I call C0. Smart clothing may have multiple layers, e.g. BC2 as RF shield, followed by two IC1 layers oriented at right angles. I will present this and other forms of existech that function as tools of self-determination and mastery over one's own personal space.
