- Augmentative and Alternative Communication and Agency
- Agency emerges from structure and constraints
- Computer-mediated augmentative and alternative communication imposes unique challenges
- Device improvements (e.g., text prediction, vocabulary sorting, customizable voices) enhance expressivity
- Augmented communicator agency is shaped by technical and colloquial factors
- Balancing constraints and partner participation is key to promoting agency
- Sociological Perspective on Agency (David R Gibson)
- Agency is exercised when conversational constraints loosen
- Constraints include turn-taking, addressing, content, and cooperative expectations
- Key Constraints in Augmentative and Alternative Communication and Task-Oriented Dialogue
- Relationship constraints
- Partner familiarity, comfort, and communication history
- Device constraints
- Throughput, input type, vocabulary, and feedback
- Task constraints
- Communication channel, output type, and information ownership
- Relationship constraints
- Role of Close Conversational Partners
- Support augmented communicator agency by facilitating third-party communication
- Increase information exchange through explanations and simplified questions
- Can both support and inadvertently reduce technical agency
- Expression of Agency in Conversation
- Technical agency
- Participating in the conversation
- Colloquial agency
- Advancing conversational objectives
- Technical agency
- Core Conversational Constraints
- One-speaker constraint
- Only one speaker at a time, disadvantaging augmented communicators
- Relevance constraint
- Limited time window for making relevant contributions
- Participation shift constraint
- Prior addressees are more likely to speak next, often bypassing augmented communicator
- Ritual constraint
- Maintaining social standing through considerate behaviors
- One-speaker constraint
- Impact of Constraints on Partner Participation
- Close conversational partners regulate turn-taking and topic dominance
- Lifelong partners (e.g., parents) participate more than paid aides
- Long partner turns can shrink augmented communicators’ response window (relevance constraint)
- Utterance-level voice output helps augmented communicators hold the floor (one-speaker constraint)
- Interaction Dynamics Between Augmented Communicators and Close Conversational Partners
- Direct addressing by third parties increases augmented communicators contributions
- Partners expand augmented communicators responses with explanations and follow-up questions
- Ritual behaviors include asking permission and clarifying information
- Increased partner participation may lead to missed contribution opportunities for augmented communicators users
- Influence of Information Access
- Close conversational partners provide informed participation when they hold task-relevant information
- When augmented communicators uniquely hold information, close conversational partners actively retrieve it
- Use of concise questioning (yes/no, short answer, follow-up) enhances efficiency
- Enhancing Communication with Third Parties
- Close conversational partners interpret augmented communicators’ unique communication traits
- They open new communication paths beyond the augmentative and alternative communication device
- Their facilitation encourages third-party elicitation of augmented communicator contributions
- Strategies to Support Augmented Communicator Agency
- Visual status displays (typing, idle, listening) inform conversation partners
- Discrete cues (wearables, peripheral signals) signal intent to contribute
- Leveraging additional context (audio, visuals) can shorten response delays
- Bookmarking conversation segments preserves context for delayed responses
- XII. Additional Constraints and Considerations
- Relationship constraint
- Augmented communicators adapt communication based on partner type
- Device constraint
- Output and input types affect speaking ability and effort
- Task constraint
- Close conversational partner support varies with access to necessary task information
- Identifying conversational goals can inform strategies to support agency
- Relationship constraint
