  • Mover, Activity Monitoring and Fall Detector, Android App (Development)

    Mover is an Android application which monitors the activity of its user. By reading accelerometer data throughout the day, the average level of activity is then translated into a type of person (Sleeper, Sitter, Lagger, Walker, Mover, or Hyper). It also makes the user aware if they are moving less or more than usual on a given day or week, hinting at when you should exercise more. Mover also includes a fall detection algorithm that triggers an audio alarm. If no movement is detected after a fall event (meaning that the user might be unconscious)), the fall event is automatically communicated to a pre-configured emergency contact through SMS or email. Mover was considered one of the Top 20 applications within the specially-designated "Lifestyle" category of the Android Development Challenge II. The Android Development Challenge consists of an annual competition launched by Google, providing awards for the best mobile apps built on the Android platform. The final judging score placed Mover in 5th place, resulting from the official judge panel evaluation and the votes from Android community members.
