Abstract: The invention is directed to an intelligent personal agent platform that uses sensor data and other inputs to monitor and detect daily activities, to monitor adherence to goals or plans, and to provide in-context personalized advice, coaching, and support to a user. The platform integrates wearable and environmental sensors that gather real-time behavior data with one or more software-based intelligent personal agents that run on cloud-based or local servers to monitor and analyze the data and provide a response, such as a request to take a certain action. Users can interact with their personal agents wherever they are via a variety of interfaces depending on the communication devices and communication networks that are available to them (e.g. mobile devices, Smart TVs, wearable displays, heads-up displays in a car, touch interfaces, and spoken natural language).
