The document describes three examples of how an embedded localization and reasoning system can be used: 1. It maps coordinates to a symbolic location like a hospital room number to inform a user where they are. 2. It evaluates a user's real activity level against a goal and generates alarms if the activity level falls below the goal. 3. It generates context-aware alarms by considering a user's location, activity, and time of day, allowing it to select the best alarm type like vibrating, soundless, or high sound.
