Paper Information

• Research Area: Human-Computer Interaction, Non-pharmacological Interventions, Cognitive Impairment in the Elderly (Dementia)
• Keywords: People with Dementia (PwD), Non-pharmacological Interventions (NPI), Technology Application, Adoption, Practical Experience, Therapists, Practitioners, Elderly

Research Background and Issues

• Identified Problems or Challenges:

  • Non-pharmacological interventions (NPI) are crucial for addressing the needs of people with dementia, but technology-mediated interventions are still in the prototype design or short-term evaluation stage.
  • Whether dementia intervention technologies can be effectively integrated into the daily work of professional practitioners remains an underexplored issue.
  • Current technologies overly focus on the needs of dementia patients while neglecting the complex processes of actual interventions and the collaborative roles of multiple stakeholders.

• Significance:

  • Dementia significantly impacts social and personal quality of life, making the development of safe and effective intervention programs a long-term priority in the healthcare field.
  • Scientifically designed non-pharmacological interventions can significantly improve the behavior, emotions, and cognitive functions of dementia patients, thereby enhancing their quality of life.

• Research Motivation and Related Work:

  • The use of technology to support interventions for cognitive impairment in the elderly is an active research area in Human-Computer Interaction (HCI), but most technologies have not progressed beyond the prototype stage in laboratories.
  • While existing literature addresses behavioral feedback from dementia patients, it rarely delves into the experiences and perceptions of therapists and other practitioners regarding these technologies.

Proposed Solution

• Methods or Solutions: The authors propose a multi-stage qualitative research approach, including observations of actual non-pharmacological intervention activities and semi-structured interviews with therapists and caregivers.

• Innovations:

  • A scientific evaluation of the professional, personalized, contextualized, and multi-stakeholder collaborative characteristics of non-pharmacological intervention processes.
  • A systematic review of the applications and limitations of technology in intervention workflows, combined with therapists' feedback to propose design recommendations.

• Implementation Steps and Techniques:

  1. Data Collection:
     • Observations of five actual intervention activities, including music therapy, reminiscence therapy, horticultural therapy, etc.
     • Semi-structured interviews with 16 practitioners, including 11 therapists and 5 caregivers.
  2. Data Analysis:
     • Thematic analysis of observation and interview data to summarize intervention characteristics and key issues.
  3. Results Reporting: Identification of four major challenges in technology-mediated interventions and practitioners' expectations for technology.

Research Findings

• Specific Findings:

  • Non-pharmacological interventions must follow professional workflows, including preliminary assessment, pre-intervention preparation, intervention execution, and post-intervention evaluation.
  • The actual use of current technologies is limited, mainly relying on projectors and computers, with rare applications of advanced interactive technologies such as Virtual Reality (VR) or Augmented Reality (AR).
  • Dementia patients exhibit low acceptance of technology, with barriers including complexity, trust issues, and potential risks.

• Advantages Compared to Existing Solutions:

  • Proposes a "personalized" intervention concept, arguing that relying solely on coarse-grained cognitive state classifications (mild, moderate, severe) cannot effectively meet patient needs.
  • Advocates for extending intervention technology from "patient-technology" interaction to a collaborative network involving "therapist-patient-multiple stakeholders."

• Experimental or Evaluation Results:

  • Current technologies fail to effectively support the complex and dynamic integration of multiple therapeutic methods in interventions.
  • Therapists expect technologies to support learning and training, provide diverse intervention materials, and assist in evaluating patient progress.

• Limitations and Future Directions:

  • Respondents had limited practical experience with technology, and more feedback on long-term technology applications is needed.
  • The study was primarily conducted in care institutions and community service centers, without addressing the needs for technology interventions in home settings.
  • Future research could explore the impact of environmental and social factors on the adoption of intervention technologies.

Design Implications

1. Personalized Interventions: Move beyond uniform cognitive level designs and adopt closed-loop designs involving therapists and patients to meet individualized needs.
2. Professional Support: Ensure technology covers critical stages of the intervention workflow, including initial assessment, implementation, and post-evaluation, and actively collaborates with therapists.
3. Multi-Stakeholder Collaborative Ecosystem: Design to support dynamic interaction and information sharing among therapists, caregivers, and patients' families to enhance intervention outcomes.
4. Education and Training: Develop interactive learning platforms using Augmented Reality (AR) or Virtual Reality (VR) to simulate scenarios and improve practice quality.

This study provides valuable references for the development of more comprehensive and practically effective dementia intervention technologies and lays a new foundation for future design guidelines.
