  • Patent number: 9524095
    Abstract: The present technique relates to a display control device, a display control method, and a program that are capable of making inputtable gesture motions easy to notice. A display control unit causes a display unit to display a gesture motion guide in a first state. When a detecting unit for detecting gesture motions detects a predetermined gesture motion, the display control unit changes the guide corresponding to the detected gesture motion to a second state and then causes the display unit to display the guide. The technique according to this disclosure can be applied to an information processing terminal that includes a display unit, for example.

  • Patent number: 9509496
    Abstract: An electronic key registration system includes an electronic key device that stores a key ID and a first piece of information. A controller is arranged in a communication subject. A registration tool writes the key ID to the controller and stores a second piece of information. Encrypted communication between the communication subject and the electronic key device is enabled after the key ID and a corresponding encryption key are written to the controller. An information center, which communicates with the registration tool, receives and compares the first and second pieces of information. The registration tool is permitted to write the key ID when receiving a signal from the information center indicating that the first and second pieces of information conform to each other.

  • Patent number: 9306735
    Abstract: An electronic key registration system includes an electronic key device having a key ID. A controller having a first piece of information is arranged in a communication subject. A registration tool having a second piece of information is configured to write the key ID to the controller. The controller compares, before electronic key registration, the first piece of information and the second piece of information. The controller permits electronic key registration when the comparison indicates that the first piece of information and the second piece of information conform to each other and prohibits the electronic key registration when the comparison indicates that the first piece of information and the second piece of information do not conform to each other.
