The Importance of User Involvement: A Systematic Review of Involving Older Users in Technology Design

BACKGROUND AND OBJECTIVES: There is a lack of understanding of how older adults' involvement and participation matters in actual design practice. This systematic literature review investigates existing empirical studies involving older users during the design of technologies and explores the nature and consequences of involving older people. RESEARCH DESIGN AND METHODS: Our literature review is informed by the guidelines of the PRISMA statement. We examined the included studies by means of thematic content analysis to identify the nature of older users' involvement and existing evidence on what consequences it has. RESULTS: In total, 40 empirical studies published in the period 2014-2018 are included in the review. Most empirical studies involve older people from local networks, with underlying stereotypical images and at lower levels of participation. The results reveal three main consequences of involving older users: learning, adjusted design, and an increased sense of participation. Furthermore, we found that user involvement is a structured process whose outcomes are contingent on a range of premises. DISCUSSION AND IMPLICATIONS: Synthesizing the results, we develop the concept of user involvement and present an analytical framework. Our results have implications for researchers and policy makers, since they throw into question the widely held assumption that involving older people inevitably yields beneficial outcomes.
