Mobiles are equipped with sensors like accelerometer, magnetic subject, and air strain meter, which assist within the system of extracting context of the person like area, scenario and so on. But, processing the extracted sensor facts is generally an aid intensive assignment, which can be offloaded to the general public cloud from mobiles. Mobile devices have become an essential part of our day to day life by which the user is able to access, create and share information at any location. This design especially objectives at extracting beneficial statistics from the accelerometer sensor records. The design proposes the utilization of parallel computing to the use of Map Reduce at the cloud for spotting human behavior primarily based on classifiers and ultimately calculating its accuracy. The sensor facts is extracted from the cellular, sent to the cloud and processed using threepopular classifier algorithms namely, Kernel Naïve Bayes, Naive Byes Classifier and K-Nearest-Neighbors. The results are verified at different scenarios of human activity and finally the accuracy is calculated using the classification algorithms.

Human activity recognition (HAR) was done in various parts of the world in the most recent decade. HAR intends to give data on human actual activity and to recognize activities in a true setting. HAR is individual of the major problems in the system vision field. Distinguishing and recognizing events or behaviors that are performed by an individual is an essential key objective of astute video frameworks. Person activity is utilized in an assortment of uti1ization zones, from person system cooperation to observation, safety, and wellbeing monitor frameworks. Notwithstanding progressing efforts in the field, HAR is as yet a troublesome errand in an unlimited climate and countenances numerous difficulties. The work incorporates various famous strategies for recognizing activity, in wearable gadgets, and cell phone sensors. Understanding the activities of humans through body sensors data collection methods and analyzing them in machine learning techniques is a demanding task in near future. Wearable devices permit catching assorted reach physiological and efficient data for the app in sports, prosperity, and medical services. Movement Recognition has numerous apps on the planet today. HAR can be characterized as distinguishing and recognizing an individual's activities, for example, "standing, sitting, walking, laying down, walk upstairs, walk downstairs, etc." the proposed system method can add to the fast execution of working activity recognition in genuine working fields.
