Though we surround ourselves with external support systems indoors and out, we all venture out of our habitats and operate as nomads, independent of these systems, for some portion of each day. Our clothing is a portable environment that can regulate body temperature, afford security and privacy, and express individual identity. Our possessions inform, sustain, and entertain us, as well as provide symbolic or physical access to valued resources.

The prospect for portable and wearable devices that extend the human mobile nature lies in the ambiguous zone between clothing and the things people carry.
