  • Patent number: 10528559
    Abstract: In an information processing system (1), a seller terminal (20) transmits a main query to an information processing server (10). The information processing server (10) receives the main query from the seller terminal (20), splits the main query into multiple sub queries in an order based on a sort condition, and transmits the sub queries to the seller terminal (20). The seller terminal (20) receives the multiple sub queries from the information processing server (10), and transmits the sub queries to the information processing server (10) in the specified order. When the information processing server (10) receives one of the sub queries from the seller terminal (20), the information processing server (10) searches for records satisfying the relevant sub query, and transmits searched records to the seller terminal (20). The seller terminal (20) receives the searched records, and displays the received records being arranged in the specified order.

  • Patent number: 10255250
    Abstract: A message processing device (10) includes an estimator (11), an extractor (12), and an indicator (13). The estimator (11) estimates words understandable to a destination user (1). The extractor (12) extracts, from a message (3) created by a transmission originator user (2), a portion that does not match the words estimated by the estimator (11). The indicator (13) indicates, to the transmission originator user (2), the message (3) with the extracted portion by the extractor (12) being in an emphasized manner.

  • Patent number: 10175940
    Abstract: A managing device (10) includes: a display (11) that displays, as a selectable object, a process executable under a current state; an inputter (12) that accepts an inputting with voice; a selector (13) which compares the displayed process with the inputting accepted while the selectable object is being displayed, and which selects any one of the displayed processes; an executor (14) that executes the selected process; and a state changer (15) that changes the current state to a new state based on the current state and a result of the selected process upon completion of the selected process. When the selected process starts, the display (11) displays, as a pre-settable object, a process becoming executable in a state prospectively changed upon completion of the selected process.

  • Publication number: 20150356654
    Abstract: When an item indicated in received order details is a designated item, an information system outputs consideration information generated based on condition information so that a purchaser can confirm the consideration information. When receiving a confirmation notification indicating that the purchaser has confirmed that he/she has understood the consideration information, the information system updates a confirmation state to a completed state. The information system outputs the confirmation state so that whether a process for finalizing the sale of the designated item is ready can be determined.

  • Patent number: 9165340
    Abstract: The image display system includes a calculation unit, a specifying unit, a generation unit and a transmitting unit. Upon change of a zoom level of a current image not containing position information to a specified value on a user terminal, the calculation unit calculates a display range of an object represented by the current image after change in zoom level. The specifying unit refers to data of a different image of the object and specifies a part of the different image indicated by the display range calculated by the calculation unit. The different image has a different resolution from the current image. The generation unit generates a next image representing the part specified by the specifying unit using the data of the different image. The transmitting unit transmits the next image to the user terminal for switching from the current image to the next image.

  • Patent number: 8825756
    Abstract: When an input area corresponding to a first service is displayed by the terminal apparatus, every time a user inputs a character into the input area, character information indicating the input character is received from the terminal apparatus. The character information is stored in a storage means included in a server apparatus different from a server apparatus of the first service and different from a server apparatus of a second service. Request information indicating a request to display an input area corresponding to the second service is received from the terminal apparatus. Instruction information, which indicates an instruction to display the input area corresponding to the request information which includes the character information stored in the storage means as character information indicating one or more characters previously input into the input area displayed by the terminal apparatus on the basis of the instruction information, is transmitted to the terminal apparatus.
