The Design of an Intelligent Pedometer Using Android

Google´s Android has become the leading platform in smart phone market. Android has also integrated various sensors including gyroscope, orientation and accelerometer, so it is quite suitable to design mobile sensor applications. Pedometer is a common auxiliary device used for maintaining health and fitness. In this paper, an intelligent pedometer is developed using Android. The user´s walking motion was detected via android sensor and pedometer application then analyzes the signal, calculates the walking distance and calories burned, and provides real time feedback to user via Bluetooth. The system provides three action modes: time-based mode, distance-based mode and count-based mode. All the tracking data are saved in SQLite database, and automatic threshold detection is used to improve the accuracy.
