Feelings by Phone

Computer scientists and psychologists at the University of Cambridge have developed EmotionSense, a system for tracking emotional behavior via smartphones using speech-recognition software and phone sensors.

EmotionSense is designed to use a phone's recording tools to analyze audio samples of the user speaking and compare them with an existing speech library. The built-in global positioning system software is used to cross-reference the audio samples with the user's location, and Bluetooth technology and the phone's recording data are used to identify who the user is talking with. The data will enable psychologists to better understand how people's emotions are influenced by their surroundings, the time of day, or their relationships with others.

"Everyone has a mobile phone, so potentially they are a perfect tool if you want to track the behavior or emotional condition of large numbers of people," says Cambridge's Cecilia Mascolo. "What we are trying to produce is a completely non-intrusive means of achieving that which also respects privacy."
