Smart-Its - communication and sensing technology for UbiComp environments

More and more Ubiquitous computing scenarios arise where
computers are embedded into everyday objects as secondary
ariefacts. The need for a generic platform to enhance such
artifacts is addressed by the Smart-Its project. TecO’s Smart-
Its are small-scale embedded computer devices that can be
easily attached to everyday objects and simply programmed for a
special task. Just like paper Post-Its are able to add some
information to an object a Smart-Its could add some computing,
perception and communication capability to an object. All this
capability was integrated into the tiny Smart-Its board itself
that is able to operate without any additional infrastructure.
This paper introduces the architecture of the Smart-Its
hardware, the design decisions for the hardware itself and
presents experiences we made while constructing and operating
these devices; some of these experience are also based on the
deployment and use of the first 160 Smart-Its devices.
