Abstract: A wireless data transmission system includes N (N is an integer equal to or greater than 2) transmission coils each disposed under water such that an opening surface thereof faces vertically upward, and N communication devices each connected in a one-to-one correspondence to a connected transmission coil which is any one of the N transmission coils and each configured to perform data communication via the corresponding connected transmission coil. Each of the communication devices performs multi-hop transmission of data, which is acquired by a data acquiring device movable under the water, based on a topology generated in advance and indicating a connection mode between the N communication devices and magnetic field coupling occurring between the connected transmission coil and other connected transmission coils adjacent thereto.

Abstract: A communication system includes an operator-side edge terminal connected to an operator terminal, wherein the operator-side edge terminal includes an I/O device configured for performing input and output of data to and from the operator terminal, a communication device for communicating with the kiosk terminal or a user-side edge terminal connected to the kiosk terminal via a network, and a controller, and wherein the controller is configured to perform a connection control for connection to the kiosk terminal or the user-side edge terminal and to perform a video transmission control of real-time transmission of a frontal video of the operator and a video of hands of the operator, both videos being shot by the operator terminal, and a frontal video of the user and a video of hands of the user, both videos being shot by the kiosk terminal.

Abstract: In order to enable a kiosk terminal to respond to a user for providing services in either way, through avatar-based communication with an avatar as a human proxy or through face-to-face communication with an operator, depending on the type of service required by the user, a controller of the kiosk terminal is configured such that, in an operator display mode, the controller displays the video of the operator on a monitor concurrently with outputting an original sound of the operator's voice from a speaker whereas, in an avatar display mode, the controller displays a video of an avatar, the avatar being generated based on feature information including operator's features extracted from the video of the operator, concurrently with outputting a converted sound from the speaker, the converted sound being generated by converting the original sound of the operator's voice to one suited for the avatar.

Abstract: A calibration method involves displaying on a monitor a frontal video of an upper body of the operator shot by a front-facing camera, the frontal video including a face of the operator, and a video of hands of the operator shot by a downward-facing camera from above; concurrently with displaying the frontal video and the video of the hands, displaying on the monitor a guidance video image as guidance information providing a guidance on a proper state of the operator's upper body in the frontal video and a guidance video image as guidance information providing a proper state of the operator's hands in the video of the hands; and, based on inputs which the operator provides according to the guidance information, adjusting the frontal video and the video of the hands.

Abstract: In order to enable a user operating a kiosk terminal to focus on the operation of the kiosk terminal while virtually eliminating any concerns about prying eyes, a controller of an operator terminal is configured such that, when a communication device receives a frontal-face video of the user, the frontal-face video being shot by a camera of the kiosk terminal such that the frontal-face video includes a background of the user, the controller displays the frontal-face video of the user on a monitor. The controller also performs face authentication on a person in the frontal-face video of the user, and upon detecting a suspicious person through the face authentication, the controller generates a screen in which identification information distinguishably identifying the user and the suspicious person has been added to the frontal-face video of the user, and displays the screen on the monitor.

Abstract: A position detection system is provided in which it is possible to inhibit deterioration in accuracy of detecting a position of a terminal after communication environment is changed even in a case where the communication environment is changed in the position detection system. In the position detection system, a first terminal measures radio wave intensity of radio waves from a plurality of wireless connection devices in the first terminal, and transmits a measurement result to a position detection server through each of the wireless connection devices. A second terminal is disposed in a prescribed position, measures the radio wave intensity of the radio waves from the plurality of wireless connection devices in the prescribed position, generates first reference data including information of the measured radio wave intensity, and transmits the first reference data to the position detection server through the wireless connection devices.

Abstract: A position detection system is provided which is capable of inhibiting an increase in system costs and improving accuracy of detecting a position of a terminal. In the position detection system, a first terminal measures radio waves from a wireless connection device or a second terminal, and transmits a measurement result to a position detection server through the wireless connection device.
