In this paper, we propose a system and methodology for using mobile phones for monitoring physical activities of a user, and its applications in assisting elderly or people with need for special care and monitoring. The method is based on processing acceleration data provided by accelerometers integrated in new mobile phones. As the mobile phone is carried regularly by the user, the acceleration pattern can deliver information related to pattern of physical activities the user is engaged in. This information can be sent to a monitoring server, analyzed and presented as different health related factors for assistance, monitoring and healthcare purposes.
