US Patent 8190359 Situation-aware personal information management for a mobile device

A technique for providing a mobile device user with a “when to leave” alarm on his or her mobile device. The user has scheduled an appointment at a given time and location in the user's personal information manager (PIM) executing on the mobile device. A representative PIM is a calendar on the mobile device. The “when to leave” alarm is provided to the end user in the form of a display widget (or “countdown alarm”) that automatically activates a given time (e.g., 30 minutes) before a latest departure time for an event in the user's PIM.
