The document discusses using mobile app and sensor data to track activity, mood, and water consumption. It finds mobile app data like water and exercise logs to be inaccurate and inconsistent for modeling, but sensor data from devices like motion sensors and door sensors to be more reliable. It concludes that while mobile app data could supplement, sensor data from a basic kit should be used as the core data, and examples a basic sensor toolkit and pricing starting at $149 for elderly activity monitoring.
7. Conclusion
•Mobile App Data
• Not suitable for activity tracking models
• Used as supplementary data
•Sensor Data
• Should be used as core data
• Define basic kit of sensors
• Use wearable
