This document will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings. It is to be noted that in assigning reference numerals to constituent elements of the respective drawings, the same reference numerals designate the same elements although the elements are shown in different drawings. Further, in describing this document, detailed description on the known functions and constructions will be omitted if they are deemed to make the gist of this document unnecessarily vague.
FIG. 1 is a block diagram showing the construction of an electronic device equipped with a touch device in accordance with a first embodiment of this document. An electronic device equipped with a touch device in accordance with a first embodiment of this document is described in detail below with reference to FIG. 1 and pertinent drawings.
An electronic device 10 equipped with a touch device 10 in accordance with a first embodiment of this document may comprises a communication unit 101, a display 102, a touch device 103, memory 104, and a controller 105.
The communication unit 101 accesses a wired or wireless network existing outside the electronic device 10 and transmits or receives data. For example, the communication unit 101 may comprise at least one of a broadcasting receiving module that receives broadcasting signals from a broadcasting station, a mobile communication module which can access a mobile communication network and transmit or receive data, and a mobile Internet module which can access a mobile Internet network, such as WiBro or WiMAX, and transmit or receive data.
The display 102 displays various pieces of information in response to a control signal output from the controller 105.
The touch device 103 is an input device capable of external touches. For example, a user can input various pieces of information or commands by touching a specific point of the touch device 103 using the finger or the stylus pen. Examples of the touch device 103 may comprise a touch pad, a touch screen, and so on. A device in which the display 102 and the touch device 103 are integrated is generally called a touch screen. Touch inputs mentioned in this document comprise all physical touches and proximity touch.
The memory 104 stores a specific program for controlling an operation of the electronic device 10 and can store various data temporarily or permanently, which are input/output and processed when the controller 105 performs an overall operation of the electronic device 10.
The controller 105 controls the constituent elements and is generally responsible for the overall operation of the electronic device 10 equipped with a touch device in accordance with the embodiment of this document.
Detailed operations of the electronic device 10 equipped with a touch device in accordance with the embodiments of this documents and a method of executing functions in the electronic device 10 equipped with a touch device in accordance with the embodiments of this documents are described below with reference to pertinent drawings. Hereinafter, the touch device 103 and the display 102 are called a touch screen 102, 103, for convenience of description. However, it is to be understood that, in this document, the touch device 103 is not limited to the touch screen.
FIG. 2 is a flowchart illustrating a method of executing functions in the electronic device equipped with the touch device in accordance with a first embodiment of this document. FIG. 3 is a diagram showing examples in which the method of executing functions is implemented in the electronic device equipped with the touch device in accordance with a first embodiment of this document. The method of executing functions in the electronic device equipped with the touch device in accordance with a first embodiment of this document can be executed in the electronic device 10 shown in FIG. 1. The method of executing functions in the electronic device equipped with the touch device in accordance with a first embodiment of this document and detailed operations of the electronic device 10 for implementing the method are described below in detail.
The controller 105 displays information on the touch screen 102, 103 [S100]. The display information may be various. For example, information, such as the desktop including a plurality of icons, web pages provided by specific web sites when an Internet is accessed, and menu trees, can be displayed on the touch screen 102, 103. For example, referring to FIG. 3, the controller 105 can display a specific web page when the electronic device 10 accesses an Internet.
The controller 105 activates the touch screen 102, 103 [S110]. The activation of the touch screen 102, 103 refers to that it is ready to input information through the touch screen 102, 103. For example, before the touch screen 102, 103 is activated, no information is input although a user touches the touch screen 102, 103 using the finger.
In the steps S100 and S110 of FIG. 3, it is assumed that a web page is not displayed on one screen. In this case, a user can view information, which is not displayed, by scrolling the screen in the left and right directions or up and down directions. When the electronic device 10 is a portable terminal, there is a case where a large amount of information cannot be displayed on one screen of the electronic device 10 due to the screen size and/or resolution problem. When the electronic device 10 is a portable terminal supporting a high resolution, lots of information can be displayed on one screen of the electronic device 10. However, a user may have to enlarge the screen in order to check information due to a limited screen size. In this case, the electronic device 10 needs to provide the scrolling function in various directions such that a user can search for web pages conveniently.
The controller 105 receives a touch input with respect to a first point (hereinafter referred to as a ‘first touch input’) on the touch screen 102, 103 [S120]. For example, referring to FIG. 3, a user can touch an arbitrary point on the touch screen 102, 103 using the middle finger of the right hand.
When the first touch input is received, the controller 105 can display an indicator, guiding a function corresponding to a second touch input to be described later on, on the touch screen 102, 103 [S130].
For example, referring to FIG. 3, the controller 105 can display indicators 201 and 202 of a graphic form, including a plurality of icons, on the touch screen 102, 103.
FIG. 4 is a detailed view of the step S130 in FIG. 3. For example, the controller 105 can display an icon 204, referring to one touch on the left region of the first point, on the touch screen 102, 103. For example, when one touch 204 on the left region of the first point occurs, the controller 105 can display an icon 205, referring to that the screen is scrolled to the left, on the touch screen 102, 103.
For example, the controller 105 can display an icon 206, in response to one touch on the right region of the first point, and an icon 207, in response to twice touches on the right region of the first point within a specific time period, on the touch screen 102, 103. When one touch 206 on the right region of the first point occurs, the controller 105 can display an icon 208, referring to that a screen is scrolled to the right, on the touch screen 102, 103. When the twice touches 207 on the right region of the first point occurs within a specific time period, the controller 105 can display an icon 209, referring to that a menu regarding web browsing is displayed, on the touch screen 102, 103.
A user can instinctively know which function will be executed when which point is touched through the indicators 201 and 202.
The step S130 can be turned on/off by a user. For example, a user can turn on or off the indicator display function [S130] by employing a graphic user interface provided by the electronic device 10.
The controller 105 receives a touch input with respect to a second point (hereinafter referred to as a ‘second touch input’) on the touch screen 102, 103 within a predetermined time period since the time point on which the first touch input has been performed [S140].
The second touch input can be received in a state where the touch on the first point keeps intact or can be received after the touch on the first point is spaced apart from the touch screen 102, 103.
The second point is a point different from the first point. The second touch input may be various. For example, the second touch input may be one touch on the second point or plural touches within a specific time period. Further, for example, the second touch input may be a touch-and-drag operation or a flicking operation.
For example, referring to FIG. 3, a user can touch the left region of the first point within 0.8 seconds from a touch time point on the first point using the index finger of the right hand in a state where the touch on the first point keeps intact [S140a]. Alternatively, referring to FIG. 3, a user can touch the right region of the first point twice using the ring finger of the right hand in a state where the touch on the first point keeps intact [S140b]. 
The controller 105 acquires the relative position of a second point with respect to the first point [S150]. The controller 105 can acquire the relative position based on coordinate values of the first point and coordinate values of the second point, which are received from the touch screen 102, 103.
The controller 105 executes a function corresponding to the relative position acquired in the step S150 [S160].
The memory 104 can comprise a database in which a relative position of the second point with respect to the first points is made to correspond to a function. The database may comprise at least one correspondence between a relative position and a function.
The relative position may comprise a distance concept. For example, different functions may correspond to one another depending on the distances and positions of the second point with respect to the first point. For example, different functions may correspond to one another when the second point belongs to a 10 to 40-pixel range to the left from the first point and when the second point belongs to a 40 to 80-pixel range to the left from the first point.
The controller 105 can execute a function corresponding to the relative position, acquired in the step S150, with reference to the database [S160]. In other words, if a relative position of the second point with respect to the first point varies, a function executed in the step S160 may vary. For example, the executed functions may be different when the second point is in a left region of the first point and when the second point is in a right region of the first point.
Referring to FIG. 3, when a user touches the left side of the first point once [S140a], the screen can be scrolled to the left [S160a]. When a user touches the right side of the first point twice [S140b], a menu 203 regarding web browsing can be displayed [S160b]. 
The controller 105 can execute different functions depending on the number of touches on the second point. For example, in the step S140b of FIG. 3, if a user touches the screen twice as described above, the menu 203 can be displayed as in the step S160b. If a user touches the same point once, the screen can be scrolled to the right.
The memory 104 may comprise a database in which the number, type, etc. of touches with respect to the second point are made to correspond different functions as well as the relative position of the second point with respect to the first point. Correspondence between the relative position of the second point with respect to the first point and the function and correspondence between the number, type, etc. of touches with respect to the second point and the functions may be set by a user. The correspondences set by a user can be stored in the database.
The method of executing functions in the electronic device equipped with the touch device in accordance with a first embodiment of this document is irrespective of which information is displayed at which point on which the first and second touch inputs are performed on the touch screen 102, 103. That is, a point on which the first and second touch inputs are performed may comprise all points on the touch screen 102, 103.
As described above, the functions that may be executed in response to the one or more touches include a scroll function, an enlarge function, a delete function and a menu display function. Other functions include a delete function, a copy function, page change/turn function, a transmit function, an upload to a website function, a download from a website function, a flag for future reference function (e.g., mark as a favorite), a storage function, a text (e.g., spell check, word count, etc.) function, a repeat function, a format text function, a format image function, etc.
FIG. 5 is a flowchart illustrating a method of executing functions in the electronic device equipped with the touch device in accordance with a second embodiment of this document. FIG. 6 is a diagram showing examples in which the method of executing functions is implemented in the electronic device equipped with the touch device in accordance with a second embodiment of this document. The method of executing functions in the electronic device equipped with the touch device in accordance with a second embodiment of this document can be executed in the electronic device 10 shown in FIG. 1. The method of executing functions in the electronic device equipped with the touch device in accordance with a second embodiment of this document and detailed operations of the electronic device 10 for implementing the method are described below in detail.
The controller 105 displays information on the touch screen 102, 103 [S200] and activates the touch screen 102, 103 [S210]. The steps S200 and S210 are identical to the steps S100 and S110 of the first embodiment of this document. However, in the step S200, at least one object is displayed on the touch screen 102, 103. Examples of the object can comprise selectable or executable icons, menus, and the like. Referring to FIG. 6, the controller 105 can display a plurality of photographs in the thumbnail view. Each of the plurality of photographs becomes one object.
The controller 105 receives a touch input with respect to a specific one of one or more objects (hereinafter referred to as a ‘third touch input’) displayed on the touch screen 102, 103 [S220]. The specific object is selected by a third touch input. For example, referring to FIG. 6, a user can select a specific photograph 301 by touching the specific photograph 301 using the middle finger of the right hand.
When the third touch input is received, the controller 105 can display an indicator, guiding a function corresponding to a fourth touch input to be described later on, on the touch screen 102, 103 [S230].
For example, referring to FIG. 6, when a touch input with respect to the specific photograph 301 is received [S220], the controller 105 can display indicators 302 and 303 of an icon form on the touch screen 102, 103.
FIG. 7 is a detailed view of the step S230 in FIG. 6. For example, the controller 105 can display an icon 306, referring to one touch on the left region of the first point, and an icon 307, referring to twice touches on the left region of the first point within a specific time period, on the touch screen 102, 103. Further, the controller 105 can display an icon 308, referring to that the specific photograph 301 is enlarged to a specific magnification when one touch 306 on the left region of the first point is generated, and an icon 308, referring to that the specific photograph 301 is deleted when the twice touches 307 on the left region of the first point are generated within a specific time period, on the touch screen 102, 103. Alternatively, when one touch on the right region of the first point is generated, the controller 105 can display an indicator 303, guiding that a menu for processing or controlling the specific photograph 301 is displayed, on the touch screen 102, 103. A user can instinctively know which function will be executed when which point is touched through the indicators 301 and 303.
The step S230 can be turned on/off by a user, which is identical to that in the first embodiment of this document.
The controller 105 receives a touch input with respect to a point different from a point on which the first touch input has been performed (hereinafter referred to as a ‘fourth touch input’) through the touch screen 102, 103 within a predetermined time period from a time point on which the third touch input has been performed [S240].
The fourth touch input can be received in a state where the touch on the third touch input keeps intact or can be received after the third touch input is spaced apart from the touch screen 102, 103, as in the first embodiment of this document.
The fourth touch input may be various as in the first embodiment of this document. For example, the fourth touch input may comprise at least one touch operation, at least one touch-and-drag operation or at least one flicking operation on a point on which the fourth touch input is performed.
For example, referring to FIG. 6, a user can touch the left-side point of a point where the specific photograph 301 is touched using the index finger of the right hand in a state where the touch on the specific photograph 301 keeps intact [S240a]. Further, for example, a user can touch the right region of a point where the specific photograph 301 is touched using the ring finger of the right hand in a state where the touch on the specific photograph 301 keeps intact [S240b]. 
The controller 105 acquires a relative position of the point on which the fourth touch input has been performed with respect to a point on which the third touch input has been performed [S250]. The step S250 corresponds to the above step S150.
The controller 105 executes a function corresponding to the relative position acquired in the step S250 [S260]. The step S260 corresponds to the step S160, but the function executed in the step S260 may be a function regarding an object selected in the step S220.
For example, referring to FIG. 6, when a user touches the left side of the specific photograph 301 [S240a], the specific photograph 301 can be enlarged [S260a]. When a user touches the right side of the specific photograph 301 [S240b], menus 304 for processing or controlling the specific photograph 301 can be displayed [S260b]. 
The controller 105 can perform different functions depending on the number of touches on the second point, as in the first embodiment of this document. For example, in the step S240a of FIG. 6, when a user touches a point, the specific photograph 301 can be enlarged, as in the step S260a, and when a user touches the same point twice, a screen or pop-up window for deleting the specific photograph 301 can be displayed.
