wireless communication unit configured to provide wireless communication; a battery configured to supply power to the smart watch; a base including a display configured to display information; first and second bands connected to the base such that the smart watch is attachable to a wrist of a user; and a processor configured to receive a palm touch input of the user on the display, and change a current status of the smart watch based on the received palm touch input. ## Claims ### Claim 1 A smart watch comprising: a wireless communication unit configured to provide wireless communication; a battery configured to supply power to the smart watch; a base including a display configured to display information; first and second bands connected to the base such that the smart watch is attachable to a wrist of a user; and a processor configured to: receive a palm touch input of the user on the display that covers the entire display, calculate a sum of a recognition strength of one or more areas of a palm touching a touch panel of the display, determine the palm touch input is a palm touch when the calculated sum of the recognition strength is greater than a size, which is previously determined, and change a current status of the smart watch based on the received palm touch input. ### Claim 2 (depends on 1) The smart watch according to claim 1, wherein the processor is further configured to: receive a gesture input of the palm touch input, and display an image on the display in accordance with a direction of the received gesture of the palm touch input. ### Claim 3 (depends on 1) The smart watch according to claim 1, wherein the processor is further configured to: receive an incoming communication event on the smart watch, and accept or reject the incoming communication event based on a length of time the palm touch input remains on the display. ### Claim 4 (depends on 1) The smart watch according to claim 1, further comprising: a speaker configured to output sound, wherein the processor is further configured to: mute or lower a volume of the sound output by the speaker based on the palm touch input. ### Claim 5 (depends on 1) The smart watch according to claim 1, wherein the processor is further configured to: execute a predetermined function previously linked to the palm touch input. ### Claim 6 (depends on 1) The smart watch according to claim 1, wherein the processor is further configured to: display different pages on the display based on the palm touch input. ### Claim 7 (depends on 1) The smart watch according to claim 1, wherein the base includes a touch pad and the at least one of the first and second bands includes a sensor, and wherein the processor is further configured to: execute a predetermined function on the display based on a user input through the sensor or touch pad. ### Claim 8 (depends on 7) The smart watch according to claim 7, wherein the predetermined function includes one of moving or scrolling information displayed on the display in a direction of the user input. ### Claim 9 (depends on 7) The smart watch according to claim 7, wherein the predetermined function includes forwarding or rewinding a media content being output on the smart watch based on a direction of the user input. ### Claim 10 (depends on 7) The smart watch according to claim 7, wherein the predetermined function includes paging through a picture gallery being output on the display based on a direction of the user input or rotating a currently displayed picture being output on the display based on the direction of the user input. ### Claim 11 (depends on 7) The smart watch according to claim 7, wherein the predetermined function includes snoozing or dismissing an alarm being output on the smart watch based on a direction of the user input. ### Claim 12 (depends on 7) The smart watch according to claim 7, wherein the predetermined function includes enlarging information displayed on the display based on the sensor sensing a stretching of the smart watch towards the user. ### Claim 13 (depends on 7) The smart watch according to claim 7, wherein the predetermined function includes locking and unlocking the smart watch based on rotating the smart watch on the wrist of the user in a predetermined rotating pattern including clockwise and counterclockwise predetermined rotations of the smart watch on the wrist of the user. ### Claim 14 (depends on 7) The smart watch according to claim 7, wherein the processor is further configured to: sense whether the smart watch is detached from the wrist of the user or whether the display is detached from the base. ### Claim 15 (depends on 14) The smart watch according to claim 14, wherein when the display is sensed to be detached from the base, the processor is further configured to transmit control signals to the detached display via the wireless communication unit to control functions of the display based on the user input. ### Claim 16 (depends on 14) The smart watch according to claim 14, wherein when the display is sensed to be detached from the base, the processor is further configured to: perform pairing with at least one external device, receive a control signal from the paired external device, and control the display based on the received control signal, and wherein the paired external device includes at least one of a head mounted display (HMD), glasses, a mobile device, and a standing device. ### Claim 17 (depends on 14) The smart watch according to claim 14, wherein when the smart watch is sensed to be detached from the wrist of the user, the processor is further configured to: perform at least one of a powering off of the smart watch, powering off the display, and entering a watch mode. ### Claim 18 A method of controlling a smart watch including a processor, a battery configured to supply power to the smart watch, a base including a display configured to display information, and first and second bands connected to the base such that the smart watch is attachable to a wrist of a user, the method comprising: providing wireless communication via a wireless communication unit; supplying power to the smart watch via the battery; displaying information on the display; receiving, via a process or the smart watch, a palm touch input of the user on the display covering the entire display, calculating, via the processor, a sum of a recognition strength of one or more areas of a palm touching a touch panel of the display, determining, via the processor, the palm touch input is a palm touch when the calculated sum of the recognition strength is greater than a size, which is previously determined, and changing, via the processor, a current status of the smart watch based on the received palm touch input. ### Claim 19 (depends on 18) The method according to claim 18, further comprising: receiving a gesture input of the palm touch input; and displaying an image of the display in accordance with a direction of the received gesture of the palm touch input.
