Capturing feedback from user sub-groups in user-centered design: A protocol integrating key user characteristics in the development of digital support for seniors’ fall preventive physical activity (Preprint)
BACKGROUND User-centered design (UCD) aims at understanding the users’ perspective and shape new solutions thereafter. UCD gives access to users’ needs and requirements and thereby improves solutions design. However, involving users in the development process does not per se guarantee that feedback from different sub-groups of users are equally shaping the development, and therefore resulting in solutions that are useful for the whole intended population. OBJECTIVE The aim of this study is to describe a protocol to integrate key characteristics of user sub-groups in collection and analysis of feedback in User-centered design (UCD) of a digital motivation support for fall preventive physical activity (PA) in seniors (older adults, 65 years of age or older). METHODS This study follows a UCD model, with early user involvement as one key principle. The protocol describes a method for systematic collection and prioritization of user feedback during the iterative development of two digital applications. For each of the four cycles in the iterative development, the aim is to recruit a group of at least 8 seniors (65 years or older, independent living) with equal distribution of men and women and a variation in both PA level and technology use. Procedures for collecting data during and after the user tests are mainly qualitative. RESULTS This paper describes a novel approach for integrating key characteristics of users sub-groups in UCD. We have developed a protocol for ensuring that feedback from both genders, persons with varied activity level and technology use are considered in the iterative development of a digital motivation support for seniors’ PA. The method has been applied in a study that has been approved by the regional ethics committee in Uppsala (Dnr 2018/044). Data collection and iterative development of the digital support has been conducted during Spring-Summer 2018 and the result is expected to be published during 2020/2021. CONCLUSIONS User involvement is the golden standard in systems design. However, it does not per se guarantee that feedback from different user sub-groups are equally shaping the development, and hence resulting in a solution that is useful for the whole intended population. Methods for systematic collection, analysis and prioritization of feedback from sub-groups might be particularly important in heterogenous groups, such as seniors. This protocol can contribute to identify and improve our understanding of potential differences in use and experiences of technical support systems for fall preventive PA among user-subgroups of seniors. This knowledge can be relevant for developing technology support that is appropriate, useful and attractive to the users and for enabling design of technology targeting specific user sub-groups, i.e. tailoring of the support. The protocol needs to be further used and investigated to understand its potential value.
