In the future buildings will be studded with sensors. Every movement
will generate a few bits of data. Every fluctuation in temperature will be
recorded. Every deviation in lighting will be noticed. These large and
complex datasets will challenge the tools we use today. Are the tools we
use to understand our data scalable to the tens of millions of records,
huge spans of time, minute details of behavior, and large geographic extent
that future sensor networks will generate?
These sensors will be installed to make our lives better: to make our
buildings more comfortable, more efficient, and more enriching places to
live and work. The sensors seem non-threatening, because they are so
simple. Everyone understands that there is a danger to installing networks
of cameras or microphones in buildings, but what of these simple sensors?
It's important to explore these questions and understand how much we can
learn about the people living under these sensors.
Our research shows that simple sensors can be used to make building
systems more efficient. They can also be used to make camera networks far
more powerful. They can be used to measure the work habits of people.
They also expose the habitual patterns of the social web that connects us
to co-workers and friends. We find that even simple sensors
reach deeply into our lives when they become ubiquitous.
