Abstract: Provided is a projection system that sets an arbitrary three-dimensional shape as a projection target and properly corrects geometric distortion of a projected image even when a user's viewpoint is not fixed. A projection unit of the projector apparatus projects a test image for first adjustment. A three-dimensional shape measurement unit measures the three-dimensional shape of the projection target. An image capturing apparatus captures the test image for first adjustment projected by the projection unit to obtain a captured image for first adjustment.

Abstract: Provided is a projection system that easily and appropriately reduces the geometric distortion of the image projected on the projection plane. The projection circuitry 3 of the projection system 1000 projects a test image onto the projection plane. The three-dimensional shape measurement circuitry 4 measures the three-dimensional shape of the projection plane. The controller 200 generates a control signal. Based on the measured three-dimensional shape data, the projection image adjustment circuitry 1 performs correction processing and rotation processing on a test, in accordance with the control signal, such that the geometrical image distortion is reduced as viewed from the user's viewpoint.

Abstract: An example of an information processing system includes: a terminal system including a hand-held type terminal; and a server. The terminal system acquires first information for evaluating health of a user. The information processing system performs an evaluation regarding health of the user on the basis of the acquired first information. The server transmits, to the terminal system, service data for providing a network service in accordance with the evaluation regarding health of the user. The server stores, in a predefined storage section, privilege information indicating a privilege to be given to the user and regarding the network service and/or the hand-held type terminal. The server updates the privilege information such that a privilege in accordance with a result of the evaluation regarding health of the user is to be given to the user.

Abstract: An example of a terminal system obtains biological information of a user, and transmits, to a server system, transmission information that includes at least one of the biological information and health information. The server system stores, as storage information, the transmission information received from each terminal system and/or information obtained from the transmission information. Further, the server system stores a condition related to generation of provision information to be provided to the user in order to improve an index obtained from the storage information or an index included in the storage information. The provision information is generated based on the storage information and the condition, and transmitted to a terminal of the user. The server system performs analysis of the transmission information which is related to a plurality of users who have been provided with the provision information and updates the condition based on a result of the analysis.

Abstract: An example of an information processing system includes a stationary type device and a hand-held type device. The stationary type device senses first user information for evaluating QOL of a user while the user is asleep. The hand-held type device senses second user information for evaluating QOL of the user while the user is awake. The information processing system performs an evaluation regarding QOL of the user on the basis of the first user information and the second user information. The first user information and the second user information may be of the same type or different types.

Abstract: An example of an information processing system obtains sensor information that includes information related to heart beat and/or pulse of a user, from a sensor which senses biological information of the user in a state where the sensor is not in contact with the user. The sensor is, for example, a Doppler sensor. The information processing system calculates an index indicating a degree of fatigue of the user, based on the sensor information. The index may be calculated by a system on a terminal side, or may be calculated by a system on a server side. The information processing system presents, to the user, information related to the index.

Abstract: An example of an information processing system includes a hand-held terminal. The hand-held terminal senses sensor information for determining an emotion of a user. The sensor information may be, for example, information of a sound sensed by a microphone, or information of an image captured by a camera. The information processing system determines the emotion of the user on the basis of the sensor information. The hand-held terminal senses the sensor information in a period during which the hand-held terminal is in a standby state. The standby state is, for example, a state in which a display of the hand-held terminal is turned off.

Abstract: An image processing system includes an image coding device serving as a host device that outputs image data, and an image decoding device serving as a client device and including a display part that displays an image based on image data transmitted from the image coding device. The image coding device includes an image quality controller that controls the image quality of an image displayed on the display part in accordance with an operation status A of the image processing system. When the operation status is a status under which a delay of displaying an image which is caused by transmission of image data from the image coding device to the image decoding device is allowed, the image quality controller increases the image quality of an image displayed on the display part.
