began working on mobile phone
sensing in 2006 when we first developed BikeNet using the Nokia
N80 and a large number of on-bike sensors. We built four of these
sensor bikes back then. Following that, we developed CenceMe for
the Nokia N95 in 2007. CenceMe runs human behaviorals models on the
phone and pushes what the
doing and the information on their surrounding context (collectively called
myspace and twitter. CenceMe was the first mobile sensing app to
be released when the appstore opened in 2008. We learnt a terrific
amount from the development and deployment of the CenceMe app.
The appstore delivery system and supporting a large globally
distributed user base has really changed how we do research - it's
challenging but exciting.
Since then we have gone on to
more sophisticated mobile sensing apps and systems including the Neural Phone (aka NeuroPhone) (2010),
EyePhone (2010), SoundSense
(2009), Darwin Phones (2009). We have just released a new app on
Andriod Market and the Appstore called VibN - catch the vibe of the
city. We've also developed two new sensing engines for mobile phones
called Jigsaw (2010) and Visage (2010) - Visage uses the front-facing
camera to infer head poses and facial expressions. Checkout the demos

- some of the more experimental apps are not available on the appstores.

of the bikes are rusting chained up outside (new england weather) and
one in the lab. I joke the business model was a stretch: each bike cost
$45 from Wallmart and $2000 for the sensor from moteiv.
did we do ground truth sensing? Checkout Emiliano modeling our quad
video helmet (no business model again) but the local Hanover cops were
quite perplexed by four people riding the sensor bikes around a small
new england town.
imagine December 2006. It is snowing. We need data for our paper. If
only we worked on computational science we'd run our algorithms on a
billion node cluster and we'd be done. But we chose bikes! Many 100s of
killometers were cycled in the freezing cold in persuit of data. It was
fun. We learnt a lot - like how you do "debugging on the go". It is a
kin to tour de france with the backup car tailing the cyclist. It was
quite exciting to see the sensor bikes on the roads around Hanover
being followed by our intrepit "debug bike". Emiliano is going to
dig out some quad video footage from the ground truth archive... stay
