In this demo, we present an application for mobile phones which can monitor physical activities of users and detect unexpected emergency situations such as a sudden fall or accident. Upon detection of such an event, the mobile phone can inform a designated center (by automatically calling or sending message) about the incident and its location. This can facilitate and speed up recovery and help process especially if the user is alone or the accident has happened in a deserted place. Such an application can be particularly useful for elderly people or people with physical and movement disabilities. The application operates based on analysis of user movements using data provided by accelerometers integrated in mobile phones.
