Talk to a virtual human through your mobile device. This app was developed as part of a study by the Character Animation and Simulation research group at the University of Southern California's Institute for Creative Technologies (http://www.ict.usc.edu). The app is part of a study to better understand how people react to virtual humans. Virtual humans are characters that are computer generated and controlled. They can be used to teach or train people. If you agree to take part in this study, we would ask you to have a chat with a virtual human and asked to answer 24 questions in an interview format. After completing your conversation with the virtual human, you will be asked to leave feedback on this study. There will be no identifiable information obtained in connection with this study. Your name address or other identifiable information will not be collected.
