Abstract: An operation section (14) receives from a user (i) a selection instruction to select a household electric appliance as an operation target from among icons included in a layout image and (ii) an operation instruction to specify an operation content for the household electric appliance selected. A control section (21) generates, on the basis of (i) household electric appliance information stored in a setting information storage section (85) and (ii) the selection instruction and the operation instruction, an operation signal for instructing the household electric appliance selected by the user to perform the operation content specified by the user. This can improve usability for a household electric appliance operation system having a function of operating a plurality of household electric appliances.

Abstract: In a case where a registration process of registering a second mode is carried out, (i) a communication terminal device (10) transmits, to an electronic device (20), according to a first communication method, an access instruction which instructs the electronic device (20) to access a server device (50), (ii) the electronic device (20) accesses the server device (50) in response to the access instruction, and (iii), upon reception of the access from the electronic device (20), the server device (50) registers the communication terminal device (10) and the electronic device (20) associated with each other. This makes it possible to improve security of a remote control system.

Abstract: A first terminal (100A) receives a handwriting instruction and a pen type, and transmits the handwriting instruction and the pen type to a server (400). The server (400) refers to a memory to convert the handwriting instruction from the first terminal (100A) into drawing data used for displaying a handwriting image corresponding to the pen type from the first terminal (100A), and transmit the drawing data to the first terminal (100A). The first terminal (100A) displays the handwriting image corresponding to the pen type based on the drawing data from the server (400).

Abstract: A network system includes a server and a plurality of terminals. The server stores contents and a status showing the state of the terminal for each room. The server stores the status received from the terminal and associated with the room, and transmits the contents and the status associated with the designated room to the terminal. Each of the plurality of terminals transmits the status to the server, transmits designation of the room input through an input device to the server, and causes a display to show the contents and the status received from the server.

Abstract: A communication terminal includes: a communication unit for transmitting and receiving data to/from a second terminal and a third terminal; a memory storing a part of the transmitted and received data; and a control unit for detecting, using the communication unit, whether the second terminal is in a first state in which the second terminal can exchange first data with the communication terminal and the third terminal or in a second state in which the second terminal cannot exchange the first data with the communication terminal and the third terminal, thereby storing the first data exchanged during the second state in the memory as second data, and for transmitting the second data to the second terminal when a transition from the second state to the first state is detected.

Abstract: A communication terminal includes: a communication unit; a memory; a first obtaining unit for obtaining first data; and a first control unit for detecting, using the communication unit, whether the communication terminal is in a first state in which the communication terminal can exchange the first data with another terminal or in a second state in which the communication terminal cannot exchange the first data with another terminal, thereby storing a part of the first data obtained during the second state in the memory as second data, and for transmitting the second data to another terminal when a transition from the second state to the first state occurs.

Abstract: A communication terminal includes an input unit, an interface for communication with another terminal and a first server, a first communication control unit receiving access information for connection with the other terminal and first information from the first server via the interface, and transmitting second information to the first server via the interface, a determination unit determining whether input of the second information satisfies a predetermined condition or not based on access information, and a second communication control unit for exchanging third information with another terminal via the interface based on the access information when input of the second information satisfies the predetermined condition.

Abstract: A communication device includes: a memory for storing first and second identification information for identifying the communication device and another communication device; a creation unit for creating a room name based on at least one of the first and second identification information; and a communication control unit for connecting to the other communication device in accordance with the second identification information, and for transmitting a creation request to a server device to create a room having the room name for allowing the communication device and the other communication device to exchange information. The communication control unit is operative in response to a first external instruction to transmit a deletion request through a communication interface to the server device to delete the room having the room name.
