The mobile terminal (400) includes a second camera (410). The interactive method includes: triggering the first camera (310) to transmit a connection request to the mobile terminal (400); and establishing a connection between the mobile terminal (400) and the head-mounted device (100) based on a consent request transmitted by the mobile terminal (400) via the second camera (410).

An equipment control method, applied to a mobile terminal, includes: positioning, in response to the mobile terminal pointing to equipment to be controlled in which an external ultra-wideband positioning device is installed, the external ultra-wideband positioning device, the external ultra-wideband positioning device having a binding relationship with the equipment to be controlled; determining the equipment to be controlled that is bound to the external ultra-wideband positioning device based on the binding relationship, in response to positioning to the external ultra-wideband positioning device; and retrieving and displaying a control interface of the equipment to be controlled that matches the equipment to be controlled. When the terminal points to the equipment to be controlled, it can automatically select and control the equipment to be controlled in which an external ultra-wideband positioning device is installed, such that the equipment that originally had no ultra-wideband positioning control can be controlled automatically and intelligently.

A method for interacting with a graphical user interface (GUI) of a television operating in a step mode in which movement of a cursor among menu items displayed on the GUI is performed stepwise in accordance with a manipulation of a direction key of the remote controller, the method including receiving, by the television, from a remote controller a signal corresponding to spatial movement of the remote controller detected by the remote controller that instructs the television to switch from (i) the step mode to (ii) a position mode of the GUI in which the movement of the cursor among the menu items is performed in accordance with the spatial movement of the remote controller and switching from the step mode of the GUI to the position mode of the GUI based on the signal.

A display system is disclosed. The display system comprises a remote control device and a display device. The remote control device receives identification information about an external device from the external device, recognizes the angle of communication with the external device, and transmits the identification information and information about the angle to the display device. The display device identifies the external device on the basis of the information about the angle, and registers the identified external device as an operable external device when the remote control device is determined to have received the identification information while oriented toward the external device.

Provided is a control object and a method for controlling a plurality of pieces of equipment. The method includes determining, with the control object, a piece of equipment to be controlled from the plurality of pieces of equipment based on a user pointing the control object at the piece of equipment to be controlled, adapting, with the control object, a control interface of the control object as a function of the piece of equipment to be controlled, receiving, through the control interface of the control object, at least one command from the user to control the piece of equipment to be controlled, generating, with the control object, control data configured to control the piece of equipment to be controlled based on the at least one command received from the user, and controlling the piece of equipment to be controlled by transmitting the control data with the control object.

A remote control apparatus is provided. The remote control apparatus includes a directional antenna, a communicator, and a processor configured to, based on a wireless signal being received from an external device through the directional antenna, identify an angle at which the wireless signal is received, based on the angle being within a predetermine range, obtain identification information of the external device by parsing the wireless signal, based on the identification information, identify whether the external device is registered to a server and based on identifying that the external device is not registered to the server, transmit a signal for requesting registration to the external device through the communicator.

A method of joining a lighting device (3′) to a network (2) and pairing the lighting device with a remote control device (7), the method comprising: transmitting a joining code to one or more lighting devices (3′) using an electromagnetic radiation signal (31); selecting a lighting device (3′) to be joined to a network (2) and paired with a remote control device (7) by directing a directional beam of electromagnetic radiation (30) onto a sensor (2) of a lighting device (3′); in response to receipt of the directional beam of electromagnetic radiation and of the joining code from the electromagnetic radiation signal, by the selected device, joining the selected device to the network if the received joining code is an access code for the network and pairing the joined device (3) with a remote control device (7) such that the joined device is controllable, on the network, by the remote control device (7).

The invention is directed at a remote-control device for controlling one or more user devices, comprising a directional optical sensor for receiving one or more optical signals from the user devices. Each optical signal encodes a device identifier by high and low signal states in periods having granulated lengths. Each granulated length is an integer number of clock periods of a transmitter clock. The transmitter clock has a clock ratio to the predetermined receiver clock, the clock ratio being a number larger than one. At least one granulated length is longer than an integer number of clock periods of the predetermined receiver clock by a fraction of the clock period of the predetermined receiver clock, which granulated length may be detected by an asynchronous receiver clock and a detection range having only two values.
