Abstract: A drone is provided that includes a controller, a time measurer that measures a present time, a position measurer that obtains a current position of the drone, and a storage that stores a time period for which the flight of the drone is permitted. The controller performs operations including determining a possible flight area of the drone in accordance with a difference between an end of the time period for which flight of the drone is permitted and the present time, and determining whether the drone is located within the possible flight area on the basis of the current position of the drone.

Abstract: Order information indicating a purchase order is received from an ordering device. Whether a display terminal corresponding to the ordering device from which the order information has been sent exists or not is determined using information which indicates correspondences between ordering devices and display terminals. Message information indicating acceptance of the purchase order indicated in the order information is transmitted to the corresponding display terminal. It is determined whether status information indicating that the message information was displayed on the display of the corresponding display terminal has been received from the corresponding display terminal or not. A cancellation period during which a process for canceling the purchase order indicated in the order information is accepted is started upon reception of the status information.

Abstract: An information presenting method includes: determining whether each event scheduled in a user schedule information belongs to a first event related to work activities or a second event not related to work activities; calculating a degree of fatigue based on a first total time of the first event and a second total time of the second event; searching for a free time after a current time, in which no event is scheduled, based on the user schedule information; determining a future position of the user in an event temporally adjacent to the free time based on the user schedule information; and generating presentation information about a service provider for relieving fatigue and that exists in a certain location around the future position of the user in response to a determination that the degree of fatigue is greater than or equal to a threshold value set for the user.

Abstract: A head-mounted display apparatus worn on the head of a user and a method for controlling the head-mounted display apparatus are disclosed. The head-mounted display apparatus includes a gesture sensor that detects a swipe gesture manipulation that indicates a direction, the swipe gesture manipulation being performed in a manipulation space, a display, a processor, and a memory storing a program. The program, when executed by the processor, executes a switching operation, in which first display information to be displayed on the display is switched to second display information according to the direction indicated by the swipe gesture manipulation detected by the gesture sensor.

Abstract: A memory storing AV data for playing back encrypted video on a playback device is provided. The AV data includes a system stream file including encrypted video information, and a management information file. The system stream file includes a first segment in which is repeated a first data unit that can be individually decrypted using a first decryption key, and has a second data unit of the same data size as the first data unit but cannot be decrypted by the first decryption key. The system stream file also includes a second segment which can all be decrypted using a second decryption key that the playback device has in common with another playback device. The management information file has a time map in which are correlated I-picture serving as random access point, and a presentation clock time of the I-picture. The I-picture is multiplexed in the second segment.

Abstract: A method includes controlling a communication terminal, which is connected to a wearable terminal via a network, to notify notification information that includes push notification to a user, without transmitting the notification information to the wearable terminal when both the communication terminal and the wearable terminal are in use, and transmitting the notification information to the wearable terminal when the communication terminal is not in use and the wearable terminal is in use.

Abstract: An information communication method is provided for obtaining information from a subject using a terminal device that includes an image sensor having a plurality of exposure lines. The method includes setting an exposure time of the image sensor so that a bright line corresponding to each of the plurality of exposure lines appears according to a change in luminance of the subject. The method also includes obtaining a bright line image including a plurality of bright lines by capturing the subject that changes in luminance, and obtaining identification information of the subject by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image. The method further includes sending the identification information to a server, obtaining place information indicating a location of the subject from the server, and displaying a location of the terminal device on a map.

Abstract: A method is provided for controlling electric equipment according to a user's speech in a speech-based equipment control system. The method includes receiving first speech information that expresses an operating instruction causing the electric equipment to operate for a first operating time. The method also includes transmitting to the electric equipment a first control command for executing a first operating process. When receiving second speech information expressing an operating instruction causing the electric equipment to operate for a second operating time, different from the first operating time before the first operating process is complete, the method further includes detecting an elapsed operating time of the electric equipment, comparing the detected elapsed operating time to the second operating time, and conditionally transmitting a second control command to the electric equipment aborting the first operating process and executing a second operating process.

Abstract: One aspect of the present disclosure provides an information presentation method for presenting a recommended guarantee content of a first device included in a plurality of devices. The information presentation method includes acquiring use history information including data indicating use of the first device (S3210), generating information indicating a use situation of the first device based on the use history information and processing defined in each type of the device (S3220), deciding the recommended guarantee content of the first device based on the information indicating the use situation of the first device (S3230), and presenting the recommended guarantee content to a user of the first device (S3240).

Abstract: An information processing method is performed by an information processing apparatus, for executing predetermined processing in relation to an object displayed on a screen. The information processing method includes: obtaining position information indicating positions detected for two or more parts of an operating body; calculating a control amount on a basis of the positions of the two or more parts, the positions being indicated in the position information; and controlling including displaying, on the screen, a control symbol including a first symbol which represents the control amount calculated in the calculating and a second symbol which represents a threshold to be a criterion for determining whether or not the control amount satisfies a predetermined condition, and executing the predetermined processing in a case where the control amount is determined to satisfy the predetermined condition.
