[Design and evaluation options of multimedia applications to support the care of people with mild dementia]. / Gestaltungs- und Evaluationsmöglichkeiten von Multimediaanwendungen zur Unterstützung der Betreuung von Menschen mit leichter Demenz.

BACKGROUND: 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. AIM AND METHOD: This study is based on 11 expert 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). RESULTS: There is a high 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. DISCUSSION: The highly variable individual life circumstances of MMD and their PAs, along with limited access options and a lack 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.

Using multimedia information and communication technology (ICT) to provide added value to reminiscence therapy for people with dementia : Lessons learned from three field studies.

BACKGROUND: In the care of people with dementia (PwD), occupational therapies and activities aiming at maintaining the quality of life of PwD, such as reminiscence therapy (RT), are taking on a more and more important role. Information and communication technology (ICT) has the potential to improve and to facilitate RT by facilitating access to and selection of biographical information and related contents or by providing novel multimodal interaction forms to trigger memories; however, interactive multimedia technology is barely used in practice. OBJECTIVES, MATERIALS AND METHODS: This article presents three exploratory field studies that evaluated different aspects of RT technology use for PwD in care homes, including the utilization of online movie databases, interactive surface touch computers as well as natural user interfaces allowing gestures and haptic interaction. In these studies, the usage of prototype systems was observed in occupational sessions by 5, 12 and 16 PwD. RESULTS AND CONCLUSION: The results indicate positive effects of technology use, e. g. in the form of verbally elicited reminiscence statements, expressed joy and playful interaction. Lessons learned for the design of technology-based RT interventions are presented and discussed.

Using Surface Table Computers to Promote the Well-Being of People with Dementia.

As the demographic change progresses, dementia is going to become a prevalent condition in many countries. In order to keep the Quality of Life (QoL) of People with Dementia (PwD) on a steady level, Assistive Technologies (AT) implemented on table-sized Surface Computers (SC) that promote playful and/or reminiscence-triggering activities turn out to be valuable tools for dementia care. This article gives an overview over two similar multimedia-based AT systems implemented on Microsoft PixelSense SCs and field-tested in dementia care institutions. The observations indicate that both systems can trigger positive emotions and activities as well as memories.
