Display apparatus controlled by motion and motion control method thereof

Abstract

A display apparatus is provided, which includes a motion recognition unit which recognizes a motion of an object that is located outside the display device, and a control unit which, when the motion of the object is recognized, determines a change amount that varies according to a motion speed or a motion distance of the object, and performs an operation which corresponds to the motion of the object according to the change amount. Accordingly, channel change or page shift can be easily performed.

1 . A display apparatus comprising:
 a motion recognition unit which recognizes a motion of an object that is located outside the display device; and   a control unit which, when the motion of the object is recognized, determines a change amount that varies according to a motion speed or a motion distance of the object, and performs an operation which corresponds to the motion of the object according to the change amount.   
     
     
         2 . The display apparatus as claimed in  claim 1 , further comprising:
 a tuner unit which selects a broadcasting channel;   a signal processing unit which processes a broadcasting signal that is received through the broadcasting channel selected by the tuner unit; and   an output unit which outputs the broadcasting signal that is processed at the signal processing unit,   wherein if a channel-changing motion that instructs a broadcasting channel change is recognized, the control unit controls the tuner unit to change and select the broadcasting channel according to the change amount in a motion direction of the channel-changing motion, wherein the change amount is differently determined according to the motion speed or the motion distance of the channel-changing motion.   
     
     
         3 . The display apparatus as claimed in  claim 2 , wherein the control unit changes the broadcasting channel by a first change amount if the motion speed or the motion distance is equal to or greater than a predetermined threshold value, while the control unit changes the broadcasting channel by a second change amount that is smaller than the first change amount if the motion speed or the motion distance is less than the predetermined threshold value. 
     
     
         4 . The display apparatus as claimed in  claim 2 , wherein the control unit controls the change amount so that the change amount is increased gradually or by stages in proportion to the motion speed or the motion distance of the channel-changing motion. 
     
     
         5 . The display apparatus as claimed in  claim 1 , further comprising an output unit which displays content that includes a plurality of pages;
 wherein if a page-shifting motion that instructs a page shift is recognized, the control unit controls the output unit to shift the page according to the change amount in a motion direction of the page-shifting motion, wherein the change amount is differently determined in proportion to the motion speed or the motion distance of the page-shifting motion.   
     
     
         6 . The display apparatus as claimed in  claim 5 , wherein the control unit shifts the content page by a first change amount if the motion speed or the motion distance is equal to or greater than a predetermined threshold value, while the control unit shifts the content page by a second change amount that is smaller than the first change amount if the motion speed or the motion distance is less than the predetermined threshold value. 
     
     
         7 . The display apparatus as claimed in  claim 5 , wherein the control unit controls the change amount so that the change amount is increased gradually or by stages in proportion to the motion speed or the motion distance of the page-shifting motion. 
     
     
         8 . A motion control method of a display apparatus, comprising:
 recognizing a motion of an object that is located outside the display device;   determining a change amount according to a motion speed or a motion distance of the object; and   performing an operation which corresponds to the motion of the object according to the change amount.   
     
     
         9 . The motion control method as claimed in  claim 8 , further comprising selecting a broadcasting channel and outputting broadcasting data;
 wherein if the recognized motion is a channel-changing motion for instructing a broadcasting channel change, the performing step changes and selects the broadcasting channel according to the change amount in a motion direction of the channel-changing motion, wherein the change amount is differently determined according to the motion speed or the motion distance of the channel-changing motion.   
     
     
         10 . The motion control method as claimed in  claim 9 , wherein the performing step changes the broadcasting channel by a first change amount if the motion speed or the motion distance is equal to or greater than a predetermined threshold value, while the performing step changes the broadcasting channel by a second change amount that is smaller than the first change amount if the motion speed or the motion distance is less than the predetermined threshold value. 
     
     
         11 . The motion control method as claimed in  claim 9 , wherein the step of determining the change amount controls the change amount so that the change amount is increased gradually or by stages in proportion to the motion speed or the motion distance of the channel-changing motion. 
     
     
         12 . The motion control method as claimed in  claim 8 , further comprising displaying content that includes a plurality of pages;
 wherein if the recognized motion is a page-shifting motion for instructing a page shift, the performing step shifts the page according to the change amount in a motion direction of the page-shifting motion, wherein the change amount is controlled in proportion to the motion speed or the motion distance of the page-shifting motion.   
     
     
         13 . The motion control method as claimed in  claim 12 , wherein the performing step shifts the page by a first change amount if the motion speed or the motion distance is equal to or greater than a predetermined threshold value, while the performing step shifts the content page by a second change amount that is smaller than the first change amount if the motion speed or the motion distance is less than the predetermined threshold value. 
     
     
         14 . The motion control method as claimed in  claim 12 , wherein the step of determining change amount controls the change amount so that the change amount is increased gradually or by stages in proportion to the motion speed or the motion distance of the page-shifting motion.
