    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: Provided is a learning support system which can enhance a learning effect by sharing a matter of interest among learners viewing a learning content. The learning support system includes: a learning content display unit configured to play and display a teaching material video; a learner information reporting unit configured to acquire biological information of a learner during play of the teaching material video and report the biological information as learner information; a region-of-attention identification unit configured to identify a region-of-attention of the learner based on the biological information; a learner information display creation unit configured to generate a screen in which the region-of-attention is superimposed on the teaching material video of another learner belonging to the same cluster as the learner; and a learner information transmission unit configured to transmit the screen to the another learner.

    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.
