Conversational Systems

Conversational Systems can range from simple, informal, bidirectional text or voice conversations (such as that beginning with the question "What time is it?") to more complex interactions (such as collecting oral testimony from crime witnesses to generate a sketch of a suspect). Conversational systems shift from a model in which people adapt to computers to one in which the computer "hears" and adapts to a person's desired outcome. Conversational systems enable people and machines to use multiple modalities (such as sight, sound and touch) to communicate across the digital device mesh (through devices — including sensors, appliances and IoT systems)
