Echo connects people using the power of the human voice. Users anonymously upload short voice recordings of their thoughts, opinions or stories that the Echo community can then interact with through comments or direct instant messaging conversations. Echo is based on research. Under the advisement of Dan Ariely, we have been conducting an experiment to test factors that can be implemented into a virtual mobile environment to create the most meaningful conversations. The data were collected in 2015 in labs at the Interdisciplinary Behavioral Research Center at Duke’s Social Science Research Institute and study rooms in the student library on Duke’s main campus with additional funding from Duke Undergraduate Research Support.
