Input device, electronic device, system comprising the same and control method thereof

A method to control an input device, the method comprising:

• transmitting utterance intention sensing information to an electronic device based on an operation of a user being identified based on a value sensed through a sensor;
• activating a microphone and providing a feedback based on a command to initiate a voice recognition and feedback information being received from the electronic device according to the utterance intention sensing information transmitted to the electronic device, the feedback provided being based on the feedback information from the electronic device;
• and
• transmitting a voice signal received via the microphone to the electronic device.

A system including an input device and an electronic device, the system comprising:

• an input device configured to, based on an operation of a user being identified based on a value sensed through a sensor, transmit utterance intention sensing information to the electronic device;
• and
• an electronic device configured to, based on the utterance intention sensing information being received from the input device, transmit a command to initiate a speech recognition and feedback information to the input device,
• wherein the input device, based on the command and the feedback information being received from the electronic device, activates a microphone, provides a feedback according to the feedback information, and transmits a voice signal received via the microphone to the electronic device.
