Analyzing technology acceptance and perception of privacy in ambient assisted living for using sensor-based technologies

People increasingly use various technologies that enable them to ease their everyday lives in different areas. Not only wearable devices are gaining ground, but also sensor-based ambient devices and systems are increasingly perceived as beneficial in supporting users. Especially older and/or frail persons can benefit from the so-called lifelogging technologies assisting the users in different activities and supporting their mobility and autonomy. This paper empirically investigates users' technology acceptance and privacy perceptions related to sensor-based applications implemented in private environments (i.e., passive infrared sensors for presence detection, humidity and temperature sensors for ambient monitoring, magnetic sensors for user-furniture interaction). For this purpose, we designed an online survey entitled "Acceptance and privacy perceptions of sensor-based lifelogging technologies"and collected data from N = 312 German adults. In terms of user acceptance, statistical analyses revealed that participants strongly agree on the benefits of such sensorbased ambient technologies, also perceiving these as useful and easy to use. Nevertheless, their intention to use the sensor-based applications was still rather limited. The evaluation of privacy perceptions showed that participants highly value their privacy and hence require a high degree of protection for their personal data. The potential users assessed the collection of data especially in the most intimate spaces of domestic environments, such as bathrooms and bedrooms, as critical. On the other hand, participants were also willing to provide complete data transparency in case of an acute risk to their health. Our results suggest that users' perceptions of personal privacy largely affect the acceptance and successful adoption of sensor-based lifelogging in home environments

Smart homes and their users:a systematic analysis and key challenges

Published research on smart homes and their users is growing exponentially, yet a clear understanding of who these users are and how they might use smart home technologies is missing from a field being overwhelmingly pushed by technology developers. Through a systematic analysis of peer-reviewed literature on smart homes and their users, this paper takes stock of the dominant research themes and the linkages and disconnects between them. Key findings within each of nine themes are analysed, grouped into three: (1) views of the smart home-functional, instrumental, socio-technical; (2) users and the use of the smart home-prospective users, interactions and decisions, using technologies in the home; and (3) challenges for realising the smart home-hardware and software, design, domestication. These themes are integrated into an organising framework for future research that identifies the presence or absence of cross-cutting relationships between different understandings of smart homes and their users. The usefulness of the organising framework is illustrated in relation to two major concerns-privacy and control-that have been narrowly interpreted to date, precluding deeper insights and potential solutions. Future research on smart homes and their users can benefit by exploring and developing cross-cutting relationships between the research themes identified

Managing care environments: reflections from research and practice

This chapter considers the role of senior staff in managing the use of space and the physical environment within care settings. These day and residential settings come under the broad umbrella of social work and social care but the care may also be organized from within health. This is a subject that does not appear on the curriculum of many management courses in the UK, but arguably it is critical in relation to social work and social care where managers are involved with residential homes, day centres and other provision where the physical environment can enhance or be detrimental towards service users' wellbeing. In such settings many activities go on under one roof, particularly in group care or when the care is provided in a person's own home. The care environment is complex and can be bounded within space, place, time and behaviour. Activities and time available compete or have different meanings for the participants. Managers have different kinds of relationships with workers and with service users. The environment in which care takes place often frames these

Managing environments

Although a context might be solid - like a building - it has different meanings for the people who use it. The impact of the physical space is the focus for 'Managing environments'. Peace and Reynolds note that any one environment may be multifunctional. Taking an innovative approach to management, they argue that a residential care home, for example, may be simultaneously a place for living for residents, working for staff and managers and visiting for relatives and other professionals. The atmosphere in a care home makes a critical difference to the experience of service users who live there. The authors review how the environmental factors that influence care may be managed and how the careful design and us of space can contribute to improved quality of life in the management of care. Peace and Reynolds also consider relationships between people, places and quality, recognising the impact of the manager on caring environments. A focus on practice here emphasises the role of the manager in drawing out debates over values and best practice to help care workers feel supported and confident about the care they provide

The design of caring environments and the quality of life of older people

There has been little systematic research into the design of care environments for older people. This article reviews empirical studies from both the architectural and the psychological literature. It outlines the instruments that are currently available for measuring both the environment and the quality of life of older people, and it summarises the evidence on the layout of buildings, the sensory environment and the privacy of residents. The conclusion is drawn that all evidence-based design must be a compromise or dynamic and, as demands on the caring environment change over time, this compromise must be re-visited in the form of post-occupancy evaluation

An evaluation tool for design quality: PFI sheltered housing

The complex procurement process entailed by the private finance initiative (PFI) means that clients need new capacities to manage their relationships with bidders and to assess project proposals if the desired level of design quality is to be achieved. To assist local authorities in their client role, a new Architectural Design Quality Evaluation Tool was developed. The aim was to improve the quality of design in residential sheltered housing, procured through the PFI. The tool was developed for and applied to a programme that will see the replacement of a local authority's entire sheltered housing stock. The tool has two functions: (1) to inform the client's assessment process and assist with the selection of the preferred bidding consortium through a series of stages in the PFI process; and (2) to improve the quality of all the submitted designs through an iterative process. Although several existing mechanisms are available for evaluating the performance attributes of buildings, few also tackle the less tangible amenity attributes, which are vital to the feeling of home. The new tool emphasizes the amenity attributes without neglecting performance

Pervasive Technologies and Support for Independent Living

A broad range of pervasive technologies are used in many domains, including healthcare: however, there appears to be little work examining the role of such technologies in the home, or the different wants and needs of elderly users. Additionally, there exist ethical issues surrounding the use of highly personal healthcare-related data, and interface issues centred on the novelty of the technologies and the disabilities experienced by the users. This report examines these areas, before considering the ways in which they might come together to help support independent-living users with disabilities which may be age-related

Extra care housing: a paradigm shift

This paper sets out to investigate if and how a spatial typology for extra care housing (ECH) can be defined within the context of housing for older people in the UK. In particular, it focuses on the concept of domesticity in relation to the perception of public, semi-public and private domains. Four sheltered housing schemes that have been remodelled into ECH within the past four years, have been selected as case studies. The spatial distribution of various public, semi-public, and private domains of the pre-remodelled and remodelled schemes have been analyzed quantitatively and interpretively, to determine how their distribution might help bolster or undermine the ethos behind ECH. Likewise, the spatial layouts of the sheltered, as well as the extra care schemes have been analysed syntactically, to determine how different spatial morphologies and their probabilistic functions might begin to help define ECH as a new type of group housing for older people. The findings of the paper suggest that the extent to which the spatial configuration of a scheme affects one’s notions of self-containment and control, has a direct impact on whether the scheme performs as a building or as a settlement. It is furthermore argued that the more a scheme functions as a settlement, the less institutional it may feel. Thus, as a typology, a successful extra care scheme can be defined as a building that works as a settlement

Designing with Care - Interior Design and Residential Child Care Final Report

This exploratory study examined the attitudes to a range of design interventions in four residential care homes for children in South Lanarkshire. The project set out to identify the benefits and disadvantages to young people and staff of a change in approach to the design of interior spaces. It was undertaken by Farm7 (specialists in design research and consultancy) and the Scottish Institute for Residential Child Care (SIRCC). The main focus of the research was to evaluate design interventions aimed at removing 'institutional' approaches to design in the care environment and improving the experience of looked after children. This involved the commissioning of interior design consultants Graven Images in the development and design of South Lanarkshire's residential children's homes. Post-occupancy evaluation of the four residential homes was undertaken with the participation of both looked after children and staff. It was envisaged that this study would contribute to the development of design guidance that will promote a more systematic approach to the design of care environments. This will allow social work and design professionals to draw on a design framework in order to significantly enhance the experience of looked after children and staff
