Fit Assist Step count and Calorie Estimator using Accelerometer

Abstract: A key challenge for mobile fitness is to develop new expertise that can assist individuals in maintaining a healthy lifestyle by keeping track of their everyday behaviours. With the advancement in technology, mobile phones or smart phones are in a hurry becoming the central computer and communication device in people’s lives. Mobile phones have got influence due to user friendly operating system Android with its wide range applications. Many instruments like Pedometers, Step count devices, Heart beat sensor’s etc., are gaining much importance as they are related to physical activities of humans. The availability of these sensors will revolutionize many sectors of our economy including healthcare, social networks, environmental monitoring and other sectors. Totally there are 14 sensors available in today’s Smartphone, and newly other sensors like finger print access and Heart monitoring sensors are also available in market. An accelerometer is a device that measures force resulting from movement. In research, these can be placed fairly unobtrusively on research participants to record the duration, frequency, and intensity of their motion. Accelerometer-based measures seem potentially more useful than other measures such as pedometers that can only count steps or other devices like video cameras or motion sensors that can only record motion in a specific area. The main objective of this paper is to develop an android application to track the user physical activity and estimate his energy expenditure using an inbuilt accelerometer and GPS in a smart phone within android device. To execute this arrangement, an android app has been developed to collect accelerometer data and calorie estimation in android SDK. It is an application implemented for smart phone with android operating system, which is open-source, easy to implement and expected to become dominant OS in the smart phone market. The need of this project is mounting now a day because today’s way of life involves less physically activity.
