Obtrusiveness of information-based assistive technologies as perceived by older adults in residential care facilities: a secondary analysis.

Abstract

With the anticipated growth in the older adult population in the next few years, information designers are examining new ways for assistive technologies to support independent living and quality of life for adults as they age. Central to the role of assistive technology to support and enhance quality of life is the development of non-obtrusive technologies. Despite the importance of non-obtrusiveness to the design of assistive technologies, there remains no standard definition of obtrusiveness or measurement instrument. A conceptual framework for obtrusiveness in home telehealth technologies has recently been proposed but has not yet been tested empirically. This project performed a secondary analysis of focus group and interview data to explore the presence of the dimensions of the obtrusiveness framework in older adults' responses to information-based assistive technologies in residential care facilities. We found the existing data contained examples of each dimension (physical, usability, privacy, function, human interaction, self-concept, routine, and sustainability) and 16 of the 22 subcategories proposed by the obtrusiveness framework. These results provide general support for the framework, although further prospective validation research is needed. Potential enhancements to the framework are proposed.
