Lonely, depressed, stressed? There's a smartphone app that can read your mood like a book. At Dartmouth, student researchers led by university professor and researcher Andrew Campbell developed and tested StudentLife, an app that can detect depression and stress levels. The app works by collecting data on phone motion, location and timing of texts and calls, sleep pattern sensors and how often the user was involved in face-to-face conversations. It occasionally listens for nearby conversation through the phone's microphone. Campbell's team created an algorithm that calculated depression and stress rates based off of the collected data. Their findings aligned with the student participants' grades and mental health benchmarks used to measure depression and stress. Story
