A control device includes: an output unit that outputs a signal for prompting an electronic device to execute a predetermined operation; a function switch unit that includes a plurality of switches each having a contactor formed such that at least a portion of the contactor is elastically displaceable in a predetermined direction; and a label body that has a display part and a protruding part protruding from the display part, the label body being mounted in a state where the protruding part is inserted into a hole in a housing and the display part is positioned on an outside of the housing. The protruding part of the label body determines a combination of open or closed states of the plurality of switches. The predetermined operation is determined according to the combination.

A display device according to an embodiment includes: a display, a communication interface comprising communication circuitry configured to communicate with at least one of a first control device including a first key and a second control device including the first key, and at least one processor, individually and/or collectively, configured to execute at least one instruction to cause the display device to: receive a first control signal corresponding to the first key, perform a first operation to output a first full screen by executing the first control signal based on the first control signal being received from the first control device while first content is being played, and perform a second operation different from the first operation to output a second full screen different from the first full screen based on the first control signal being received from the second control device while the first content is being played.

The systems described herein provide a remote keyboard service for a media device on a computing device without having to invoke an application or unlock the computing device. The computing device can receive a message indicating that a text input field on the other device is selected and present a notification to the user prompting the user to invoke the virtual keyboard on the computing device to provide text input to the selected text input field. The computing device can receive user input selecting the notification and present a virtual keyboard for providing text input to the other device. The computing device can receive keyboard input from the user selecting characters and send the characters to the other device. The other device can then user the characters as text input to the selected text input field.

The present invention provides a self-photographing system and method. The self-photographing system comprises an electronic device having a taking photo or recording video, and a self-photographing device. The electronic device is disposed on the self-photographing device. The self-photographing device comprises a controller, an infrared receiver and a rotating platform. The controller defines a first area from a signal sensing range of the infrared receiver. The controller controls the rotation of the rotating platform, so that the infrared receiver is able to receive the infrared signal in the first area of the signal sensing range, and therefore a lens of the electronic device can take photo or record video for the user in a particular angle.

An embodiment of the invention provides an apparatus for providing a media service while outputting a content. The apparatus includes: a processor; a memory for storing one or more program instructions executed by the processor; and a control signal receiver unit for receiving from a remote control a control signal resulting from a key input made by a user, where the program instructions determine whether the key input is a normal input or a force input by comparing a sensing level, which is associated with a pressure or an area by which the user presses the key, with a preset value; identify the content outputted on the screen when the control signal is received, when the key input is a force input; and execute an operation different from an operation of a normal input for the key, according to a combination of the identified content and the force input.
