Description: A textual interface is a type of user interface that allows interaction through text, commonly used in chatbots. This type of interface is based on written communication, where users can send messages in text form and receive responses also in text. Textual interfaces are fundamental in the creation of chatbots, as they facilitate interaction between humans and machines in an intuitive and accessible manner. Often, these interfaces are implemented in various digital platforms, applications, and customer service systems, allowing users to make inquiries, obtain information, or resolve issues without the need for a complex graphical interface. The main characteristics of textual interfaces include simplicity, speed in communication, and the ability to process natural language, enabling chatbots to understand and respond to user inquiries effectively. Additionally, these interfaces are highly scalable, meaning they can handle multiple interactions simultaneously, making them a valuable tool for businesses looking to improve customer service and optimize user experience.
