User interfaces for older adults to support social interaction through digital technology: a systematic review update

PurposeThis systematic review aims to update the results related to user interfaces and digital technologies that support the social interactions of older adults. Multiple innovative technological forms in existing research were evaluated to obtain evidence that digital technologies improve older adults' quality of life and social well-being.Materials and methodsA search for relevant studies published in the last five years was conducted using the databases of Google Scholar, IEEE Xplore, PubMed, Scopus, Springer Link and Web of Science.ResultsOf the 4959 records identified, a total of 29 studies met the inclusion criteria. The findings were reviewed in three areas: social interaction of older adults supported by user interface, the digital technologies used in the user interface, and the effects of user interfaces on the social interactions of older adults.ConclusionsFuture research should develop digital technologies and service models to enhance the quality of life of older adults. Long-term solutions to promote social interaction in older adults require more user interface support. Community connection-based user interfaces can support existing social relationships and develop new social circles for older adults. An update on recent advances in research on user interfaces that support social interaction with older adults.Community connection-based user interfaces can support existing social relationships and develop new social circles for older adults.The application of digital technology needs to consider the establishment of long-term and deep social relationships for older adults.Future research should develop and explore digital technologies with a broader social perspective.
