SPECs: personal pervasive systems

We have devised a system of wireless SPECs-small personal everyday computers-that can be worn or attached to a place or thing and, unlike Active Badges, can be networked without a centralized computer. Our approach increases availability on a per-user basis, rather than for an entire community, to create a truly personal pervasive system. Users themselves deploy and maintain these autonomous devices throughout their own normal living areas: at the office, in their car, at home, and even in public spaces.
