         2 . The wearable device according to  claim 1 , wherein the first gesture of the digital device is detected by the digital device. 
     
     
         3 . The wearable device according to  claim 2 , wherein the first mode is an incoming call mode, the second event is an incoming message event and the second mode is an incoming message mode. 
     
     
         4 . The wearable device according to  claim 3 , wherein the incoming message event is an incoming event which most recently occurs to the digital device. 
     
     
         5 . The wearable device according to  claim 1 , further comprising a gesture sensor unit configured to sense a gesture with respect to the wearable device,
 wherein the processor is further configured to detect a second gesture of the wearable device.   
     
     
         6 . The wearable device according to  claim 5 , wherein the second gesture is made by moving the wearable device upward. 
     
     
         7 . The wearable device according to  claim 5 , the processor is further configured to display the second event information on the display unit until the second gesture is detected. 
     
     
         8 . The wearable device according to  claim 7 , the processor is further configured to transmit a second signal to the digital device in response to the second gesture. 
     
     
         9 . The wearable device according to  claim 8 , wherein the second signal causes the digital device to be switched from the first mode to the second mode. 
     
     
         10 . The wearable device according to  claim 7 , wherein the processor is further configured to switch the wearable device from the second mode to the first mode in response to the first gesture and a detection of the second gesture. 
     
     
         11 . The wearable device according to  claim 1 , wherein the processor is further configured to provide a notification in response to the first signal. 
     
     
         12 . The wearable device according to  claim 1 , further comprising a position acquisition unit acquiring a position of the wearable device. 
     
     
         13 . The wearable device according to  claim 12 , wherein the processor is further configured to transmit a third signal regarding a first altitude of the wearable device to the digital device, and wherein the first gesture is detected based on the first altitude by the digital device. 
     
     
         14 . The wearable device according to  claim 1 , the processor is further configured to switch the wearable device form the incoming message mode to the incoming call mode, if the first gesture occurs within a predetermined time after the first signal is received. 
     
     
         15 . A control method of a wearable device comprising:
 receiving a first signal from a digital device in communication with the wearable device, wherein the first signal is transmitted from the digital device when a second event is detected by the digital device which is in a first mode;   in response to the first signal, executing a second mode on the wearable device and displaying a second event information detected by the digital device on a display unit of the wearable device; and   in response to a first gesture of the digital device, switching the wearable device from the second mode to the first mode, wherein the first gesture is made by moving the digital device downward.   
     
     
         16 . The control method according to  claim 15 , wherein the first mode is an incoming call mode, the second event is an incoming message event and the second mode is an incoming message mode 
     
     
         17 . The control method according to  claim 15 , further comprising:
