Abstract: Provided is a method, performed by a first device, of performing a voice command. For example, a method, performed by a first device, of performing a voice command includes receiving a packet including voice data of a user broadcast from a second device; performing authentication of the user, by using the voice data included in the packet; detecting a control command from the voice data, when the authentication of the user succeeds; and performing a control operation corresponding to the control command.

Abstract: A method and a device for transmitting/receiving data between a wireless terminal and an electronic pen by recognizing a user's motion are provided. The method includes displaying a transmission list that is to be transmitted when data transmission to the electronic pen is requested after an approach of the electronic pen is detected, configuring data selected from displayed data in the transmission list as transmission data when a selection request signal is detected, and transmitting the configured transmission data to the electronic pen when transmission of the configured transmission data is requested.
