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 an attitude detector that detects the attitude of the head-mounted display apparatus, a manipulation detector that detects a predetermined manipulation performed on the head-mounted display apparatus, a display, and a processor. The head-mounted display apparatus switches a display of first display information to second display information according to a change in the attitude detected by the attitude detector. However, if the manipulation detector detects the predetermined manipulation, the head-mounted display apparatus maintains the display of the first display information without switching to the second display information even if there is a change in the attitude detected by the attitude sensor.

Abstract: In a method causing a processor in a communication terminal to execute operations that include; detecting whether the communication terminal, which is connected via a network to a wearable terminal that is attached to part of a body of a user, is being manipulated; if the communication terminal is detected as not being manipulated, transmitting notification information that includes push notification to a wearable terminal; if the communication terminal is detected as being manipulated, transmitting the notification information to the communication terminal, without transmitting the notification information to the wearable terminal.

Abstract: In a wearable terminal, a controller determines whether a direction of a display surface detected by a detector is within a first angle range. In a case where a latest direction of the display surface is out of the first angle range, the controller puts the display in a sleep state, but otherwise the controller puts the display in an active state. Furthermore, the controller specifies a second angle range from the second reference direction. The controller switches the display from the sleep state to the active state in a case the controller determines that the plurality of directions of the display surface detected in the first period and that the direction of the display surface newly detected by the detector is out of the second angle range. In the second display control, the display is switched from the sleep state to the active state even when the newly detected direction of the display surface is out of the first angle range.

Abstract: A wearable terminal includes: a body having a display that performs display, a sensor that detects a first angle of rotation by which the display has been rotated with respect to a first axis as an axis of rotation, and a controller that controls the display according to the first angle of rotation; and a band that is connected to the body and extends around the forearm in an arcuate shape, wherein the first axis is perpendicular to a second axis and is parallel to a direction in which the forearm extends, when the first angle of rotation is within a first angle range, the controller causes a first display image displayed, and when the first angle of rotation changes from the first angle range to a second angle range, the controller causes a part of the first display image and a part of a second display image simultaneously displayed.

Abstract: A control method comprises: receiving from a first vehicle, first information including a first required amount of the energy source; receiving from a second vehicle, second information including a second required amount of the energy source; and determining, when a total sum of required amounts of the energy source received from two or more vehicles including the first vehicle and the second vehicle is larger than a remaining amount in a storage reservoir, i) a first reserved supply amount of the energy source for the first vehicle, wherein the first reserved supply amount is smaller than the first required amount, and ii) a second reserved supply amount of the energy source for the second vehicle. The second reserved supply amount is determined within a range where a total sum of the first reserved supply amount and the second reserved supply amount does not exceed the remaining amount.

Abstract: A wearable terminal includes a display input unit which displays an image, which corresponds to a program identical to at least one program stored in another wearable terminal among a plurality of programs stored in a storage unit and is used for starting the program in response to an operation performed thereto, on a display screen based on another terminal program information, which is received in a case where another wearable terminal is authenticated, and receives an operation with respect to the image displayed on the display screen, and a control unit which performs control such that in a case where the display input unit receives an operation with respect to the image, the program corresponding to the image which receives the operation is started and a communication unit is allowed to transmit specific information associated with the program to another wearable terminal.

Abstract: In a method causing a processor in a communication terminal to execute operations that include; detecting whether the communication terminal, which is connected via a network to a wearable terminal that is attached to part of a body of a user, is being manipulated; if the communication terminal is detected as not being manipulated, transmitting notification information that includes push notification to a wearable terminal; if the communication terminal is detected as being manipulated, transmitting the notification information to the communication terminal, without transmitting the notification information to the wearable terminal.

Abstract: A control method causes a computer of an information terminal having a first display to: receive electronic mail from an electronic mail server by using a mail application for executing transmission and reception of the electronic mail, the mail application being stored in a memory of the information terminal; transfer the received electronic mail to a wearable terminal having a second display; receive viewing information from the wearable terminal, the viewing information indicating that the electronic mail was displayed on the second display at a time; determine whether the electronic mail is being displayed on the second display, based on the viewing information; and automatically display, on the first display, a reply-mail creation screen for creating a reply mail to the electronic mail that was displayed on the second display, upon determining that the electronic mail is being displayed on the second display, and the computer launches the mail application.

Abstract: If a customer has picked up a product from a display shelf, a display device displays first sales promotion information. In an information providing system, if the customer has not been attracted to the product and has returned the product to the display shelf, the display device displays second sales promotion information, which is different from the first sales promotion information. By displaying the different pieces of sales promotion information using the display device provided near the product, it is possible to promote the product to the customer in two different ways, thereby stimulating the customer's desire to buy the product and reducing loss in opportunities to sell the product.
