As the elderly population increases, automatically supporting their life is becoming a priority in the research community. To be able to provide such support, however, the focus of measuring ageing and health should shift from the current symptom-based approaches to personalised situation-aware approaches. As there are currently no established roadmaps on how to measure healthy ageing, we are collaborating with the Gerontology Department at the University of Zürich (UZH) on methods for measuring various cognitive and physical properties based on sensor, video, audio and textual data. Through Prof. Mike Martin, who is the chairman of the Center for Gerontology in UZH, we are involved in the effort of the World Health Organization to elaborate the concept of healthy ageing and establish a dynamic system model of health. This involves the semantic analysis of the health dynamics within and across persons and time.
