Challenges in health smart homes

This paper presents an overview of the challenges in developing Health Smart Homes targeting, in particular, elderly and impaired people. As such, it identifies the current endeavors as well as the main areas of research

Using CAN to retrofit houses for quadriplegic people

DETIThis paper describes the B-Live® system targetted to automate house appliances for severely impaired people, in particular quadriplegic. This system has been developed at Micro I/O for enhancing the quality of life and the independence of its potential users. The envisaged application is the retrofitting of common dwellings. The B-Live system is described and details on its software, hardware and CAN-based communications architecture are provided. A survey of the supported appliances and interfaces is presented as well as a description of the B-live configuration and operation procedures. The adequacy of the B-Live system to improve the autonomy of the envisaged users was informally evaluated by C5 and C6 patients at a demonstration house located in the CMRRC Rovisco Pais, a rehabilitation center near Aveiro, in Portugal. The conclusion is that the system has a short learning curve and can cope with the requirements of its potential users. The use of CAN in this application opens the possibility to include safety critical real-time systems in the BLive system. This is the case of the monitoring of the ventilator used for quadriplegic people that require breath assistance

An Ecological Approach to Smart Homes for Health Care Services: Conceptual Framework of a Smart Servicescape Wheel

Background: Smart homes are considered effective solutions for home health care for the elderly, as smart home technologies can reduce care costs and improve elderly residents' independence. To develop a greater understanding of smart homes for health care services (SHHSs), this study accentuated the necessity of ecological approaches with an emphasis on environmental constraints. This study was based on 2 rationales: (1) users are inclined to perceive the service quality and service experience from environments (ie, servicescape) owing to the intangibility of health care and the pervasiveness of smart home technologies, and (2) both service domains are complex adaptive systems in which diversified and undefined service experiences-not only a few intended service flows-can be generated by complex combinations of servicescape elements. Objective: This study proposed the conceptual framework of a Smart Servicescape Wheel (SSW) as an ecological approach delineating the extensive spectrum of environmental constraints in SHHSs. Methods: The SSW framework was established based on a literature review. Results: Generally divided by perceptible and imperceptible servicescapes, the SSW consists of the perceptible Physical scape (ie, hardware components, environmental cues, and human states) and Social scape (ie, service relationships and social relationships) as well as the imperceptible Datascape (ie, computing intelligence, databases, and communication networks). Following the ecological approach, each category of the SSW is subdivided and defined at the level of components or functions. Conclusions: The SSW's strengths lie in the various application opportunities for SHHSs. In terms of service planning and development, the SSW can be utilized to (1) establish the requirements for SHHS development, (2) associate with work domain analysis by defining component layers, and (3) understand the real contexts of SHHSs for the enhanced prediction of diverse service experiences. Regarding service management, it can be applied to develop measurement items for the operation and evaluation of SHHSs.This work was supported by the Ministry of Education of the Republic of Korea and the National Research Foundation of Korea under grant NRF-2017S1A5A8019275.
