Abstract: A method is provided for developing a computer-based dialogue interface for an automated or computerized system using input device technology. The dialogue interface is disposed between the automated system and an end user, with the dialogue interface receiving input from the end user and providing output to the end user in response to the input. In an illustrative embodiment, the method comprises the following steps. A system designer(s) defines a plurality of requirements applicable to the dialogue interface. The dialogue interface is then designed to meet these requirements. The automated system is simulated with at least a first person, and the end user is simulated with at least a second person. The dialogue interface is evaluated by facilitating an interaction between the first and the second persons through the dialogue interface. Based on the interaction between the first and the second persons, the dialogue interface is evaluated.
