The telephone is typically used for conversations, some important and others not. Yet, an Intel team is pioneering new ways to use the phone as a health monitoring tool- not just a communication device. In this fascinating TED presentation, Eric Dishman anticipates that an automated system will call elderly individuals to monitor their health. The system calls and logs data such as call pickup times, responses to cognitive tests, and other behaviorial cues.  The system then builds an individual's baseline health profile using this information. If, in the future, an individual's responses deviate from their baseline then it could be a warning sign of trouble.
