Summary
This study applies Clark's theory to augmented communication, focusing on how shared meaning (common ground) is built in real-time conversations. It examines how device features impact this grounding process for augmented speakers and their partners.
Area of Science:
- Linguistics
- Communication Studies
- Human-Computer Interaction
Background:
- Augmented speakers often face challenges in establishing common ground during conversations.
- Existing research on device-mediated communication is fragmented.
Purpose of the Study:
- To apply Clark's theory of language use to understand conversations involving augmented speakers.
- To analyze how common ground is achieved and how media characteristics influence the grounding process.
Main Methods:
- Utilizing Clark's theory of language use.
- Applying a joint action analysis to conversations mediated by word-boards and Voice Output Communication Aids (VOCAs).
- Examining how participants navigate media constraints to solve communication problems.
Main Results:
- Conversations involving augmented speakers are organized around specific media constraints.
- Participants actively manage communication to establish and maintain common ground despite technological limitations.
- Device characteristics significantly affect the grounding process in augmented communication.
Conclusions:
- A joint action framework can explain communication performance in device-mediated interactions.
- This model offers a unified approach to reconcile diverse findings in augmented communication research.
- The proposed model can guide future research and evaluation of communication performance for augmented speakers.
