• To identify specific user needs and preferences for future AAC development.
• To inform directions for impactful AAC technology innovation.

Main Methods:

• Conducted interviews and surveys with individuals with speech/language challenges and their loved ones.
• Collected qualitative feedback on user difficulties and preferences with current devices.
• Analyzed quantitative data on usage, preferences, and ratings of hypothetical devices.

Main Results:

• Identified significant gaps between current AAC device capabilities and user needs.
• Consolidated qualitative feedback on user experiences with commercial AAC devices.
• Collected and published de-identified quantitative data for further research.

Conclusions:

• Future AAC development should focus on customizable input, context-aware output, and personalized devices.
• Addressing expressed user needs can significantly improve AAC device effectiveness.
• Technological advancements can facilitate the creation of more impactful AAC solutions.
