Abstract: A communication device according to an embodiment includes an interpreter, a storage, and a generator. The interpreter is configured to interpret a content of a message addressed to a target user. The storage stores information on a personal feature of the target user. The generator is configured to generate a response message simulating a response by the target user on the basis of the content of the message addressed to the target user, which is interpreted by the interpreter, and the information on the personal feature of the target user stored in the storage.

Abstract: A childcare support service offering system includes a terminal and a server. The terminal includes a camera and performs operation control and processing of transmitting terminal usage situation data including image data acquired by being picked up by the camera to the server. The server performs image analysis on the received image data, recognizes the user that watches the terminal, judges a gaze of the recognized user, and judges a degree of interest for the terminal based on the gaze. When the judged degree of interest becomes equal to or less than a predetermined threshold value, the server transmits a changing instruction for causing an operation in the terminal to be changed to another operation to the terminal.
