Abstract: In order to provide an interactive interface that arouses a user's sympathy and realizes a continuous interaction having much information, an interactive system of providing the interactive interface of performing an interaction with a user includes a computer and a measurement device of measuring a signal related to a user's speech. The computer calculates a first feature amount indicating feature of a user action in the speech of the user, based on the signal measured by the measurement device, calculates a second feature amount that is a control value of a response action to the user performed by the interactive interface, based on the first feature amount, calculates a control time of adjusting a timing of controlling the response action depending on the type of the response action, and controls the interactive interface, based on the second feature amount and the control time.

Abstract: An autopoietic information processing system which is an information processing system for collecting and outputting information includes: a means that inputs first information; a means that collects second information related to the first information; a means that selects third information from the second information; a means that outputs second or third information; a means that collects the second information by setting the third information as new first information; a means that merges the existing second information and new second information at a predetermined rate; a means that selects new third information from the merged second information; and a means that outputs the merged second information or the new third information. The means are recursively operated to continuously provide new information which leads to awareness and discovery of a user.

Abstract: An interaction system that interacts with a user is disclosed. The interaction system includes: an input device that receives a speech signal of the user; a computing device that determines a speech content of the interaction system for a speech content acquired from the speech signal of the user such that a frequency distribution of speech feature values of the speech content of the interaction system approaches an ideal frequency distribution; and an output device that outputs the determined speech content of the interaction system.

Abstract: An interaction system that provides an interaction interface comprising: a computer and a device that obtains information, wherein the computer stores information for managing data in which a type of a second feature value is associated with a listening pattern that defines a tendency of a response action performed by the interaction interface on a user; calculates a first feature value that is an index for evaluating a change in state during speech by the user on the basis of information obtained by the device; calculates second feature values on the basis of the first feature value; selects a target second feature value from among the second feature values; selects the listening pattern corresponding to the target second feature value; and generates output information for controlling the interaction interface on the basis of the selected listening pattern.
