Abstract: According to an embodiment of the present invention, when impression formation for a listener with respect to a speaker is controlled, a speech voice signal of the speaker is acquired, a voice feature is extracted from the speech voice signal, a bias to an impression made on the listener by the speech voice signal is determined based on the extracted voice feature, a bias control signal for controlling the bias occurs based on a determination result of the bias and information indicating a preset control direction of the bias, and a stimulation control signal for giving external stimulation to the listener is generated in accordance with the bias control signal, and the generated stimulation control signal is output.

Abstract: An aerial image display device includes a display, a retroreflective material, a retardation plate, a beam splitter, and a polarizing plate. The display, the retroreflective material, and the beam splitter are disposed on an installation bottom surface. The display emits polarized light of a display image that is the basis of an aerial image in accordance with a polarization direction of incident light. The retroreflective material reflects incident light in an incident direction. The beam splitter reflects polarized light of the display image emitted from the display toward the retroreflective material in accordance with the polarization direction of the incident light and has polarized light of the display image reflected by the retroreflective material transmitted therethrough. The polarizing plate is disposed above the installation bottom surface, extends across an imaging plane of the aerial image, and has polarized light transmitted through the beam splitter transmitted therethrough.

Abstract: A space production apparatus according to one aspect of the present invention includes a light source, a viewing angle limiting surface, and a mirror. The light source emits light for projecting a first image. The viewing angle limiting surface selectively reflects the light emitted from the light source toward a predetermined angular range, and is disposed such that an observer area where an observer is expected to be located is located in a direction outside the predetermined angular range. The first image is projected onto the viewing angle limiting surface. The mirror reflects the light emitted from the light source and reflected by the viewing angle limiting surface.

Abstract: One aspect of the present invention is an aerial image display system including: a display device that displays a display image; and an optical system that includes a retroreflective member and an optical member having an optical characteristic of reflecting part of incident light and transmitting part of the incident light, and displays an aerial image corresponding to the display image toward a viewer, in which position information on the viewer is acquired, and an angle of a reflective surface of the retroreflective member is rotated by a designated angle from a direction of the viewer as a reference on the basis of the position information on the viewer acquired.

Abstract: In one aspect of the present invention, a retroreflective member is arranged in a state where a reflective surface is orthogonal or near-orthogonal to a viewing direction of a viewer. A first optical member is arranged between the viewer and the retroreflective member in a state where an action surface is parallel or near-parallel to the reflective surface of the retroreflective member, a mirror image space is formed between the first optical member and the retroreflective member, and a real space is formed in a space where the viewer is present. A second optical member is arranged in the mirror image space in a state where an action surface is inclined at a predetermined angle with respect to the viewing direction, and a mirror image space movement region is formed between the second optical member and the retroreflective member.

Abstract: According to one embodiment of the present invention, information indicating reaction states of a plurality of listeners to an event is acquired, and reaction aggregation information in which the reaction states of the plurality of listeners are aggregated is generated based on the acquired information indicating the reaction states. Then, control information for variably controlling vibration and temperature is generated based on the generated reaction aggregation information, and the generated control information is output to be presented to a speaker of the event.

Abstract: An emotion of a person in a video can be easily understood by a computer to execute: an identifying step of identifying an expression mode that is understandable by a user with respect to a certain emotion of the person on the basis of information input by the user; and an attaching step of attaching information, which indicates the certain emotion, to the video in the expression mode identified by the identifying step in a case where it is estimated that the person included in the video displayed for the user has expressed the certain emotion.

Abstract: A computer executes: a learning procedure of learning a model for estimating an addition mode of a symbol representing a state of a person in a video to the video on the basis of learning data indicating the addition mode of the symbol to the video; and an addition procedure of estimating the addition mode of the symbol to the video of a web conference using the model learned and adding the symbol to the video in the addition mode estimated, thereby increasing an amount of information that can be grasped from the video.
