Such moments are happening more and more often these days, as researchers seek out innovative ways to exploit mobile phones.
Phones are increasingly being equipped with not only accelerometers, but also cameras, Global Positioning System (GPS) receivers and Internet connectivity. Many of them can support programs devised by anyone, not just the phone's manufacturer, which means that digitally savvy scientists can write and distribute mobile-phone software for everything from monitoring traffic to reporting invasive species.

- "We've really never had a technology other than human observation itself that is as pervasively deployed out in the world,"
- This makes mobile phones a natural tool to study road traffic,
- But mobile phones could provide a cheaper way to collect the information, because scientists can piggyback on the phone companies' existing communications infrastructure.
- In November last year, Bayen's team launched Mobile Millennium: a project to generate real-time traffic estimates with GPS-enabled mobile phones in a region near San Francisco. Volunteers download the software and transmit their position and velocity to a central computer system.
- Because mobile phones can travel into areas that lack other sensors, they are revealing traffic flow on smaller, previously unmonitored roads outside the highway system
- with a mobile phone, Rubinsky reasoned, a doctor in a remote village could transmit raw measurements from a relatively inexpensive data-collection device, such as an ultrasound transducer, to a processing centre in a major city. The centre would then reconstruct the image and transmit it back to the phone.
- Other groups are creating mobile-phone applications to conduct health surveys, analyse blood samples and report natural disasters.
- Mobile phones also have the potential to enhance the role of the citizen scientist. Information collected by non-scientists has traditionally been seen as suspect because it is difficult to verify, says Estrin. But with the help of mobile-phone cameras and GPS, which can label data with a precise location, observations taken by everyday citizens could become more reliable. "The fact that people can do real-time uploading of geo-tagged information changes that story,"
- Estrin's team is working on a set of projects that will enlist citizens to submit field observations via mobile phone to a central database.
- the team also plans to supply a phone-based reporting system for Project BudBurst, a citizen-science effort to measure the effect of climate change on plant blooming.
- Lukac and his colleagues are hoping to deploy a test set of accelerometer-equipped phones in an earthquake-prone area and eventually establish a mobile seismic network.
- Mobile phones may "open up the demographics of the people who could participate" in citizen science, says Jeff Goldman, director of programme development at CENS
- arah Williams, director of the Spatial Information Design Lab at Columbia University in New York, and her colleagues are working to attach air-quality sensors to mobile phones so that people can send pollution measurements via text message to a central database.
- Using the phone data, Eagle's team was able to classify students studying business from those studying other subjects with 96% accuracy. If the researchers examined only the first 12 hours of a user's day, they could correctly predict the person's movements for the rest of the day 79% of the time⁶
- "In reality, and depressingly, you can compress my behaviour down to a few vectors,"
- Eagle hopes to detect common behavioural patterns, such as changes in movement or calling frequency, that occur during disease outbreaks, which could help alert public-health officials to the early stages of an epidemic.
- Eagle's research illustrates how mobile phones can be used to collect accurate, large-scale data about real social interactions, unlike other methods such as interviews or virtual-world observations,
- At the other end of the spectrum, some groups are exploring public-health applications at the individual level.
- Despite the challenges, researchers are excited about the possibilities of a planet-wide network of these miniature travelling computers. About 85% of the world's population has access to a mobile signal, says Susan Teltscher, head of the Market Information and Statistics Division at the International Telecommunication Union,
- Although mobile phones will not replace traditional scientific instruments, says Estrin, they make up in availability for what they lack in finesse. "If you can't go to the field with the sensor you want," she says, "go with the sensor you have."
