Computer Vision and Wireless Sensor Networks in Ambient Assisted Living: State of the Art and Challenges

Due to demographic reasons, the percentage of elderly population in developed countries is rapidly increasing, thus leading to much bigger demand of alternative caring solutions such as Ambient Assisted Living (AAL). This paper presents the recent research trends in AAL, as well as the main challenges to its development. The paper focuses on two significant fields in AAL– computer vision and Wireless Sensor Networks (WSN), and provides details about the state of the art and challenges to research in these fields
