Abstract

Falls are a major health problem among the elderly. The consequences of a fall can be minimized by an early detection. In this sense, there is an emerging trend towards the development of agent systems based on mobile phones for fall detection. But when a mobile phone-based fall detector is used in a real-world scenario, the specific features of the phone can affect the performance of the system. This study aims to clarify the impact of two features: the accelerometer sampling frequency and the way the mobile phone is carried. In this experimental study, 5 participants have simulated different falls and activities of daily living. Using these data, the study shows that the sampling frequency affects the performance of the detection. In the same way, when a fall detector intended to be attached at the body is carried in an external accessory, the performance of the system decreases.
