Design and evaluation options of multimedia applications to support the care of people with mild dementia

Abstract

In order to cognitively and physically activate people with dementia (MMD) in institutional settings, there are numerous touch-based multimedia applications specifically designed for this target group that are actually being used in practice. In contrast, the use of similar applications in domestic settings has been relatively limited. This study is based on 11expert interviews guided by questions and examines design options and requirements for application content as well as requirements for study designs to provide evidence of the effectiveness of touch-based multimedia applications for MMD and their caregiving relatives (PA). There is ahigh degree of consensus regarding the criteria for requirements for touch-based multimedia applications. Acceptance is highly dependent on user competence, usage practices, experiences and incentive structures; however, there are diverse opinions about their structural and content-related design. The quality of life is mentioned as an essential evaluation parameter for multimedia applications. The highly variable individual life circumstances of MMD and their PAs, along with limited access options and alack of suitability of the multimedia applications, may be causal factors for their relatively limited use, especially in domestic settings. Daily performance capabilities and individual disease progression pose special requirements for the scientific evaluation and the demonstration of the effectiveness of touch-based multimedia applications.
