Background:

  • The field of Augmentative and Alternative Communication (AAC) has a history of persistent research issues.
  • A seminar convened 45 AAC researchers and professionals to discuss fundamental research challenges.
  • This paper provides an overview of themes and perspectives from the seminar.

Purpose of the Study:

  • To provide an overview and background of issues discussed at the Augmentative and Alternative Research Seminar.

  • Analysis of terminological issues within the AAC field.
  • Identification and discussion of common themes from presentations and papers.

    • Main Results:

    • Terminological clarity is needed, particularly regarding "complex communication needs," symbols, signs, and communication modes (verbal/nonverbal).
    • Key themes include the significance of context, the comprehension-production relationship, multimodality, and interaction analysis.
    • The importance of using typical interaction as a framework for understanding AAC interaction was discussed.

    Conclusions:

    • Current AAC research issues mirror those from earlier years, underscoring the need for a stronger evidence base.
    • Further research is required to understand complex relationships in AAC, including environment, comprehension, and multimodal communication.
    • Applying findings to AAC practice remains a significant challenge, despite progress in understanding typical interactions.
