My data science talk at Strata+Hadoop World Conference, San Jose, February 18th 2015
Two billion people carry a smartphone. In every single smartphone, more than 20 sensors continuously track all kind of behavioral and environmental data, from geo-location to remote influences like magnetic field and local gravitation. Each device is able to collect millions of data points per day.
We can draw a colorful picture of people’s everyday lives from the data we collect via smartphones. To tell the data-story, we need to translate the raw measurements into meaningful events, like “driving a car”, “strolling in a mall”, or even more intimate, like “being nervous”.
We will show how to access the phone’s data, how to derive complex events from the phone’s raw data, and how to bring it into a meaningful story, and how to make it work for businesses. Cases we’ll show: an app for the automotive industry to support ecological driving, learning about preferences of Chinese passengers at an international airport, and supporting people suffering from osteoporosis to stabelize their condition and maintain mobility.
We will in particular tell, how we found a good way to deal with privacy and informational self-determination, and how to give users a fair deal and transparancy to the data, that we collect with their cooperation in our projects.
