Summary
This paper presents the iterative design and clinical deployment of Scrapbook, a web platform that supports psychologists in conducting personalized reminiscence therapy and cognitive stimulation sessions for people with dementia using biographical materials. The work is grounded in formative studies with nine health professionals (interviews) and 531 informal caregivers (online surveys) that revealed a central tension: all stakeholders value biographically-rich personalized materials for therapy, but these materials are difficult to obtain, organize, and maintain. Photos are the most commonly used materials, followed by music and everyday objects, with caregivers focusing primarily on recalling people (55.7%) over places or events. The platform evolved through three iterative deployment phases over approximately seven months in two clinical settings (a rehabilitation clinic and a care home), involving four clinicians and 26 patients. Phase 1 focused on agile reminiscence therapy — psychologists register patients with biographical keywords (interests, relevant places) that automatically seed content collection from Flickr and YouTube APIs, then select and sequence materials for slideshow-based therapy sessions. Phase 2 added cognitive stimulation activities using personalized materials: jigsaw puzzles with biographical photos, memory flashcard games, street view navigation of personally relevant places, quizzes personalized to the patient's background, and a "Touch" game where patients identify specific people in flying photos. Phase 3 introduced group therapy support with interest-matching across patients, a mobile Android app for caregivers to contribute materials and receive session feedback, and additional activities including sorting life events and speaking exercises with microphone-based answer detection.
Key findings
The platform was well accepted by clinicians, with some choosing to use Scrapbook exclusively for sessions and others integrating it with traditional methods. Positive impacts on patients were observed: one patient who previously could not formulate sentences was able to sing entire songs when presented with music he enjoyed; psychologists reported improvements in attention, apathy levels, ambulation, well-being, and mood. Patient engagement was notably higher with biographical materials than with generic personalized content — puzzles with personal photos elicited more engagement than puzzles with non-personal images, even in patients with advanced dementia. Activities with adjustable difficulty levels (puzzles, flashcards, quizzes) were important for accommodating different disease stages. However, overall platform usage was underwhelming — clinicians used it less frequently than hoped, partly because it still carried connotations of being supplementary or informal rather than a core therapy tool. The caregiver mobile app, despite being viewed positively in concept, saw very limited adoption (only two caregivers contributed via the app), attributed to low technological skills among elderly Portuguese caregivers. Group therapy features were used but suboptimally — clinicians created a single generic profile rather than individual profiles for group participants, undermining the personalization benefits. Key practical lessons included: the platform must be extremely fast to set up (registration and session creation must be near-instant); patient-facing screens must be completely clean of any UI elements that could cause distraction; all materials must be pre-validated by psychologists before patient exposure; and the process of collecting biographical materials from families requires careful handling of privacy concerns and fear of losing personal photos.
Relevance
This research demonstrates how personalization — a core theme in web accessibility — applies directly to therapeutic interventions for people with cognitive disabilities. The finding that biographical materials produce significantly higher engagement than generic content, even in advanced dementia stages, underscores the power of person-centered design in cognitive accessibility. For accessibility practitioners, the paper offers several transferable insights: designing technology for people with cognitive impairments requires extreme simplicity in user-facing interfaces (no browser tabs, bookmarks, or navigation elements visible); the technology must serve the clinical workflow rather than impose a new one; and involving multiple stakeholders (clinicians, caregivers, patients) creates both opportunities (richer personalization) and challenges (adoption barriers, privacy concerns, varying digital literacy). The gap between positive reception and actual adoption is a common pattern in assistive technology — tools that clinicians praise in concept may still not integrate smoothly into existing routines, suggesting that technology adoption in clinical accessibility settings requires sustained support and alignment with established therapeutic practices.
