Designing for Relational Maintenance: New Directions for AAC Research

Document Information

• Subject Area: Human-Computer Interaction (HCI), Assistive Technology
• Keywords: Augmentative and Alternative Communication (AAC), relational maintenance, ALS (Amyotrophic Lateral Sclerosis), cerebral palsy, assistive technology, accessibility

Research Background and Issues

• Issues and Challenges: Research on Augmentative and Alternative Communication (AAC) has traditionally focused on input speed, with insufficient attention to higher-level communication goals such as relational maintenance. For individuals with language and motor impairments, this neglect significantly impacts their interactions with close family members or caregivers.
• Research Significance: Language is a vital tool for transmitting information and fostering social connections. For individuals with motor and language impairments, AAC is not only a means of expressing needs but also plays a critical role in maintaining social ties within intimate relationships. These individuals require effective tools to sustain their relationships and quality of life.
• Motivation and Related Work: Although current AAC systems have improved in terms of input and speed, their slow response times still hinder social participation. Additionally, studies in nursing and psychology have highlighted the profound impact of physical disabilities on marital, familial, and psychological relationships. Against this backdrop, the potential role of AAC in relational maintenance remains underexplored.

Research Methods

• Primary Research Questions:
  1. How do AAC systems support and constrain users and their caregivers in the process of relational maintenance?
  2. What changes occur in communication methods and relational interactions in the context of AAC use?
• Research Methods:
  • Qualitative data collection through interviews, focusing on ALS or CP (cerebral palsy) patients and their family caregivers to explore their experiences.
  • Analysis conducted in two ways: inductive coding based on emerging issues and deductive application of relational maintenance strategy theory.
  • Research scope includes five dyads (AAC users and caregivers), with an emphasis on intimate relationships such as spouses, siblings, and parent-child dynamics.

Solutions

• Proposed Approach:
  • The authors suggest expanding the scope of AAC research from traditional functional studies like input speed to higher-level goals, including relational maintenance and achieving social purposes.
  • AAC users strive to achieve social participation and interaction, while caregivers bear significant burdens in supporting communication. The study explores design opportunities within these interdependent dynamics.
• Innovative Contributions:
  • Combining qualitative analysis with the relational maintenance framework provides new perspectives on AAC in complex social contexts.
  • Specific design directions are proposed, such as using technology to alleviate relational conflicts, support nuanced emotional expression, and enhance AAC users' autonomy and social identity.
• Implementation Steps and Key Techniques:
  • Conduct thematic analysis based on interview content to identify the dynamics of collaboration between users and caregivers in overcoming communication barriers.
  • Apply the Relational Maintenance Strategies Framework to infer information contexts and interaction patterns.

Research Outcomes

• Specific Findings:
  • Three major inductive themes were identified: interconnected factors, shared workload, and communication barriers.
  • Deductive analysis identified nine relational maintenance strategies, further expanding and supplementing their behavioral manifestations in AAC contexts.
• Experiments or Evaluations:
  • The study reveals the impact of AAC on relationships between spouses, parents and children, and siblings, showcasing its profound effects through detailed case studies.
  • In-depth future research directions are proposed (see below).
• Limitations and Future Directions:
  • Limited to a small number of participants and the specific socioeconomic context of North America.
  • Future studies are recommended to validate findings across more diverse communities.
  • Development of unique relational frameworks focusing on AAC's impact within intimate relationships is suggested.

Future Research Directions and Recommendations

Expanding Research Scope

1. Alleviating Relational Tensions and Enhancing Emotional Expression: Provide more support for implicit emotional communication.
2. Enhancing Social Identity and Interaction Roles: Explore ways to help AAC users engage more actively in social support.
3. Supporting Social Etiquette and Intimate Interactions: Provide assistance for sensitive topics and improve the enjoyment of low-risk conversations.

Solutions to Specific Issues

1. Overcoming Multiple Barriers in Dynamic Scenarios: Develop an ecosystem of complementary assistive technologies for diverse contexts.
2. Reducing Burden through Collaborative Perspectives: Design tools to help caregivers and AAC users jointly manage communication pace.

Through these directions, the study not only expands traditional technological research but also inspires broader discussions on building a more comprehensive, human-centered AAC ecosystem.
