Conversational Interface

A user interface that enables interaction through natural language, either spoken or typed, allowing users to communicate with a system using conversational dialogue rather than traditional graphical controls. Conversational interfaces include voice assistants, chatbots, and dialogue systems. They are particularly valuable for accessibility because they provide an alternative interaction modality for people who cannot use visual or touch-based interfaces, such as blind users or those with motor impairments. When well-designed, they reduce the need to navigate complex visual layouts and can support hands-free operation.
