The scientists propose an application that can sit in an operating system, server, browser, phone, or wearable device continuously monitoring a person’s behavioral data: interactions with other people or computers, social media posts, search queries, and online activities. The app may activate sensors to record voice and speech, videos and images, and movement, such as detecting “when the user engages in excessive shouting by examining the user’s phone calls and comparing related features with the predication model.”
