Abstract | Many researchers have studied the problem of classifying patient activities in order to monitor and assist them in their daily life. This study aims to develop a classification model for recognizing users‟ activity with data obtained by the sensors in smart mobile phones. In particular, we focus on the use of the accelerometer, which is a common sensor in new mobile phones such as the iPhone and the Nokia N97. Th e positions and the postures of the mobile phones are captured by the accelerometer, and classified using a Support Vector Machine (SVM) algorithm. Training and test data for seven activities (stationary, standing, running, walking, ascending and descendin g stairs, cycling and driving a car) were collected in with the phone in four postures (head up/face in, head up / face out, head down/ face in, head down/face out ) and six locations on the body, with a classification accuracy of above 92.5% using the SVM a lgorithm. The results provide a solid base for future research in activity classification. |
