This paper examines an assistive technology targeted to ageing people: a safety alarm and the related service system. A safety alarm is not only a technical device; with the related system, it can be seen as a holistic opportunity for innovation. The operation of safety alarm systems and services depends on many critical points. Potholes lying in safety alarm systems are identified in this study, taking into account the technology, services and organizational network. The potholes are studied as sources and opportunities for potential innovation. Service, social, organizational, process and marketing innovations—combined with technology—are significant parts of innovation activity related to the ageing population. A technical device is not used in a vacuum: there is also organization and service acts, as well as the user with her or his values, appreciations, state of health, and so forth. These factors impact the variety of innovation potential in assistive technology. This paper examines the existing technology and related services as well as various innovation opportunities related to uncovering their shortcomings.
