Designing for Transactional Moments: Features of Tools for Child-centred Speech Language Teletherapy

Research Background and Issues

• Identified Problems or Challenges: This paper focuses on the characteristics of online and face-to-face speech-language therapy tools, particularly how they support or hinder interactive "transactional activities" between therapists and children. Current research has not thoroughly explored the role of tools in remote and face-to-face therapy.
• Significance: Early intervention is critical for children's language development. When geographical or social constraints prevent face-to-face therapy, remote therapy becomes an important alternative. Therefore, understanding how tools influence interaction and effectiveness in remote therapy is of great importance.
• Research Motivation and Related Work: The study aims to explore the material and social impacts of tools in therapist-child interactions. Existing research primarily focuses on the perspectives of parents and therapists or the standalone use of digital technologies, neglecting the role of tools in actual therapy settings.

Solution

• Proposed Approach or Solution: Through the analysis of 10 video recordings, the paper examines three therapy cases in detail to observe how tools are used in therapist-child interactions and how they influence therapy goals. The study adopts a design-oriented research approach and a socio-material analysis perspective.
• Innovations:
  • Identified four necessary conditions for designing tools to support interaction: levels of interaction, spatial control, open interaction points, and content flexibility.
  • Proposed a concept that integrates social interaction and tool design to optimize the application of therapy tools in remote environments.
• Implementation Steps and Key Techniques:
  • Conducted case studies using video recordings in natural settings and multimodal analysis.
  • Utilized video data analysis tools for coding and classifying interaction patterns.
  • Proposed key design features to improve existing tools, making them better suited to support social and goal-oriented activities in language therapy.

Research Outcomes

• Specific Findings:
  • Identified how the functional characteristics of physical and digital tools can support or hinder transactional activities in language therapy.
  • Proposed design requirements for tools to address critical aspects of language therapy, including better support for children's autonomy, engagement, and learning outcomes.
• Comparison with Existing Solutions:
  • Unlike traditional digital tools, this study emphasizes how tools serve social interaction and transactional activities in therapy environments rather than merely providing recording or gaming functions.
  • Stressed that tool design should consider not only functionality but also support for social and interactive aspects.
• Experimental or Evaluation Results:
  • Case analyses revealed that tools with clear interactive functions, controllable spatial mechanisms, and diverse content more effectively support therapy goals.
  • Tools that fail to align with children's interests or lack flexibility can disrupt coordinated interactions and reduce therapy effectiveness.
• Limitations and Future Directions:
  • Limitations:
    • The small sample size (10 videos) limits the generalizability of the findings.
    • Feedback from therapists and parents has not been thoroughly explored.
  • Future Directions:
    • Expand the sample size to include more diverse types of language disorders and therapists.
    • Develop preliminary technology prototypes based on this research and test their effectiveness with actual users (children, therapists) through co-design methods.
    • Further investigate how digital tools can encourage social interaction and playfulness in language therapy for children.

Through this study, the design of language therapy tools can achieve a better balance between functionality and interactivity, meeting the needs of both face-to-face and remote therapy while ensuring that the therapy process remains flexible enough to cater to children's interests and social needs.
