  • Publication number: 20200413119
    Abstract: The present disclosure relates to a control device, a control method, an electronic device, and a program that enables an operation in a natural manner for switching between and remotely operating various control target devices. A plurality of control target devices emits infrared light codes each including a unique ID in a predetermined pattern. A user holds a controller and directs an infrared light receiving unit toward a control target device. At this time, a control state is established for the control target device specified by an infrared light code received by the controller. After the control state has been established, when a user rotates a main body of the controller, a control parameter in accordance with the amount of rotation is calculated, and a control command in accordance with the control parameter is transmitted to the control target device to control the control target device. The present disclosure can be applied to a remote controller.

  • Patent number: 10755117
    Abstract: A method of determining obstacles determines if a detected object detected outside a subject vehicle is an obstacle for the subject vehicle on the basis of a predetermined determination criterion. In this method, a determination is made whether or not the detected object detected outside the subject vehicle is a driver or passenger of the subject vehicle. When the detected object is not the driver or passenger, a determination is made whether or not the detected object is an obstacle for the subject vehicle on the basis of a first determination criterion. When the detected object is the driver or passenger, a determination is made whether or not the detected object is an obstacle for the subject vehicle on the basis of a second determination criterion with which the detected object is less likely to be determined as an obstacle for the subject vehicle than with the first determination criterion.
