Conversational Interface

An interface that enables interaction through natural language dialogue, either spoken or text-based, rather than through traditional graphical controls like buttons and menus. Conversational interfaces are significant for accessibility because they can reduce cognitive load, support users with motor impairments who cannot manipulate physical controls, and provide a more intuitive interaction model for people unfamiliar with technology. They are increasingly used in assistive technologies including smart speakers, telepresence robots, and virtual assistants.
