A large number of ambient assisted living technologies coexist without a common language between them. They have different user interfaces, communication infrastructures and maintenance plans, which limit the inclusion of efficiency-enhancing solutions in the home care sector. Also, deployment of applications and devices are overly complex, and cannot be handled by the healthcare staff or citizens themselves, but most often require support from technical personnel. This increases cost and reduces the feasibility of implementing new technologies. Following a participatory design approach the CareStore project investigated the feasibility of creating an open and flexible infrastructure for facilitating seamless deployment and integration of assisted living devices and applications on heterogeneous platforms without requiring intervention from technical staff. A range of limitations and challenges are identified, and a solution is suggested.
