R e v i e w Buckheit 1 has suggested that the impact of the ageing society could be of greater concern than the current financial crisis. The ratio of persons 65+ years of age to the labour force (15-64 years) will rise from 25% in 2005 to 31% in 2020 and further increase to 52% in 2050 2. Since the absolute number of registered nurses is expected to remain constant 3 , an enormous pressure on the health care sector will result. Most gerontechnologies are developed for functional compensation and assistance to ease the burden on the care sector 4. In this study we address home automation 5 , robotics 6 , assistive technology 7 , geriatric telecare and telemedicine 8 (Table 1). These technologies have long histories of use supporting the aging society by improving the quality of life of older persons through ICT (Information and Communication Technology) 5-8. More than ten years ago Healy 9 argued that ICT would change health care, even then telematics was found to be cost effective in terms of time, money, quality and accessibility. Currently, most home automation, robotics, assistive technology, geriatric telecare, and telemedicine systems are stand-alone, having no operational dependencies on other systems. These technologies have individual taxonomies, methods, protocols and standards that may not integrate easily. Nevertheless, there exists a huge conceptual overlap between the intended functionality of apparently similar systems. For example, tracking people with ultra wideband (UWB) sen
