Dialogue Design

Dialogue design in human-computer interaction refers to the structured planning of the conversational exchange between a user and a system, defining how input is accepted, how the system responds, and how errors are handled across interaction turns. In accessible interface design, dialogue design is critical for ensuring that multimodal and non-visual systems provide clear prompts, appropriate feedback, and intuitive error recovery strategies. Good dialogue design considers the user's mental model, the sequencing of system responses, and the graceful handling of input failures across different modalities.
