The notification "Activity pattern change detected" alerts users to significant deviations in routine behaviours, classified into three distinct events based on the involved activities and corresponding sensors:
1. Independence Abnormal Activity: This event is triggered when unusual patterns are detected in the data from wearables, sleep sensors, door, chair, tap, and toilet sensors, indicating potential changes in the individual's independence or mobility.
2. Hydration Abnormal Activity: This refers to unexpected activity patterns concerning kettle usage, tap activations, and fridge openings, which could signify changes in hydration habits.
3. Nutrition Abnormal Activity: This event is marked by irregular activity concerning fridge access, possibly pointing towards alterations in nutrition or eating habits.
Each of these events aids in monitoring an individual's wellbeing by drawing attention to areas of change that might require further observation or action.
