    Evaluating nonvocal communication is crucial for severely dysarthric individuals. A new system was developed to assess performance by recording messages and partner interaction times.

    Area of Science:

    • Augmentative and Alternative Communication (AAC)
    • Speech-Language Pathology
    • Human-Computer Interaction

    Background:

    • Increasing communication options for severely dysarthric individuals necessitate performance evaluation methods.
    • Current assessment techniques may not fully capture the nuances of nonvocal communication.

    Observation:

    • A novel data collection and analysis system was implemented.
    • The system recorded complete messages from nonvocal communicators.
    • Durational measures of communication partner receiving time were collected for each message.

    Findings:

    • The system successfully gathered comprehensive data on nonvocal communication.
    • Performance metrics included message content, partner interaction duration, partner identity, and location.

  • This facilitated a detailed assessment of communication effectiveness.

    • Implications:

    • This system provides a foundation for objective evaluation of AAC strategies.
    • Findings can inform the development of more effective communication aids for dysarthric individuals.
    • Further research can refine this system for broader clinical application.
