JournalAIde: Empowering Older Adults in Digital Journal Writing

Research Background and Issues

• Challenges and Issues Identified by the Authors:

  • Although digital journaling has become an effective way for older adults to express themselves and record their lives, this process is challenging for many, requiring reflection, self-expression, and the ability to organize thoughts. Specific issues include:
    1. Lack of confidence, especially when comparing their work to high-quality examples from others.
    2. Insufficient ability to express and organize thoughts, including difficulty starting and lacking appropriate vocabulary.
    3. Difficulty maintaining attention and focus, particularly when tasks are isolated or when encountering obstacles.
  • Existing research on digital content creation often focuses on younger populations or professional writers, with limited studies supporting older adults in digital writing, especially tools that provide reflective and creative support.

• Importance of the Study:

  • Digital journaling offers multiple health benefits for older adults, including helping maintain cognitive function, enhancing social connections, and promoting self-reflection and emotional expression. It can serve as an important tool for memory preservation and intergenerational communication.
  • Current tools supporting older adults in creating digital content either focus on visual or assistive functionalities (e.g., voice input for visually impaired users) or fail to address the complex and reflective needs of journaling, leaving significant gaps in research and design.

• Motivation and Related Work:

  • This study aims to design a tool to address existing gaps, supporting older adults in overcoming challenges related to confidence, ability, and focus during the writing process, leveraging the latest large language model (LLM) technology to provide personalized, collaborative, and reflective assistance.

Solution

• Proposed Approach:

  • Designed and developed an interactive system named “JournalAIde” to enhance older adults' ability to create digital journals, providing support for confidence building, thought organization, writing expression guidance, and intuitive visual editing prompts.

• Innovative Features of the Solution:

  1. Confidence Building Through Peer Experiences: Showcasing works from other older adults with similar writing levels to provide indirect experience and boost confidence.
  2. Modular Writing Support: Breaking the writing process into planning, expression, and revision stages, with tailored assistance for each stage.
  3. LLM-Based Generation and Collaboration: Utilizing chatbots and sample text generation to assist users in organizing ideas and language expression.
  4. Color-Coded Intuitive Editing Prompts: Providing consistent visual cues for generated text to guide users in modifying AI-generated content while maintaining personalized style.

• Implementation Steps and Key Technologies:

  • The system consists of three views:
    • Square View: Displays works from peer users as inspiration and reference.
    • Editing View: Supports paragraph-based writing, combining text and images, and intelligent revision functionalities (based on GPT4 API).
    • Chatbot View: Helps users recall and organize ideas through conversational interactions and assists text generation using large language models.
  • Features intelligent tagging (based on consistency with user input) and customizable prompt templates for fine-grained content generation and adjustment.

Research Outcomes

• Specific Results:

  • JournalAIde effectively enhanced older users' confidence, writing ability, and engagement:
    • Compared to baseline systems, scores for confidence support, ability improvement, and user engagement were significantly higher (all with large effect sizes).
    • Users felt the generated text expressed their emotions and thoughts, increasing their willingness to share their works.

• Experiment or Evaluation Results:

  • Experiment 1 (Laboratory Controlled Study):
    • JournalAIde significantly improved users' writing confidence (U=141.00, p<0.001) and ability (U=144.00, p<0.001).
    • Overall user satisfaction, content expression accuracy, and willingness to share were all significantly enhanced.
  • Experiment 2 (10-Day Real-World Deployment):
    • The system stimulated participants' interest in exploring different writing types and enhanced motivation through peer work sharing.
    • Users gradually exhibited greater autonomy but required more guidance and transparency in interactions with the LLM.

• Advantages Compared to Existing Solutions:

  1. Provides comprehensive writing support while addressing specific challenges faced by older adults in digital writing, such as lack of confidence and reflective expression.
  2. Introduces efficient generation and assistance functionalities based on cutting-edge LLM technology, balancing collaboration and autonomy.

• Limitations and Future Directions:

  1. Learning Curve: Due to the system's complexity, users need time to adapt to features like color-coded prompts and generation adjustment hints.
  2. Lack of Personalization: Insufficient adaptation to users with varying writing abilities and styles; future work could incorporate more flexible personalization features.
  3. Dependency on LLM: Some users expressed concerns about over-reliance on AI potentially affecting cognitive training; further optimization is needed to balance its role as a cognitive aid.
  4. Need for Long-Term Studies: Lacks validation of long-term effects; future research could track and evaluate the stability of content creation and changes in cognitive function over time.

This study demonstrates the significant potential of technology in supporting older adults in digital journaling, not only helping them overcome technical and writing barriers but also providing valuable theoretical and practical guidance for future interactive system design.
