Description

Device and method for intuitive file management on terminal touch screen {APPARATUS AND METHOD FOR INTUITIVE FILE MANAGEMENT ON THE TOUCH SCREEN IN MOBILE COMMUNICATION TERMINAL}

The present invention relates to an apparatus and method for intuitive file management in a terminal touch screen, and more particularly, to an apparatus for easily using various functions that were available only in a PC by drawing a simple symbol on the terminal touch screen. It is about a method.

In general, in order to delete text or music files from the touch screen of a mobile phone, check a separate check mark item and then select Delete from the menu. In addition, file management such as creating or copying a new folder is inconvenient to execute through a menu provided by a mobile phone. Therefore, it is common to manage a file through a program provided by a specific mobile phone manufacturer in connection with a PC.

In the case of a PC, when using a file or folder management, use the Shift or Ctrl key on the PC keyboard to select a large number of files or folders at once. However, implementing the Shift or Ctrl key in a small mobile or front touch screen mobile environment is cumbersome and inconvenient for the user. Therefore, most mobile phones currently have to select a file or a folder one by one, which causes a problem that the user is very inconvenient and consumes a lot of time when managing a large number of files.

An object of the present invention is to provide an apparatus and method for intuitive file management in a terminal touch screen.

Another object of the present invention is to draw a simple symbol (symbol) on the terminal touch screen various functions (for example, Copy & Paste, Delete, Move, Shift & Ctrl & Cancel keys, etc. and specific pages or menus that were available only on the PC) The present invention provides an apparatus and a method for easily using a function such as viewing, file transfer, and arranging a specific icon.

Another object of the present invention is to provide an apparatus and method for increasing space utilization and reducing the number of clicks or time required for file management in a space-limited miniature terminal touch screen.

According to an embodiment of the present invention to achieve the above object, a method for managing a file on a touch screen of the terminal, when a single point touch on the touch screen is detected, the file included in the area where the single point touch is detected Selecting, and checking whether a continuous multipoint touch is detected on the touch screen, searching for a symbol command corresponding to the continuous multipoint touch when the continuous multipoint touch is detected, and checking the selected file. For example, the method may include executing a symbol command according to the found symbol command.

According to an exemplary embodiment of the present invention, a device for managing a file on a touch screen of a terminal includes a touch screen unit for checking whether a touch is detected on the touch screen, and a single point touch on the touch screen. When detected, selects a file included in the area where the one-point touch is detected, checks whether a continuous multi-point touch is detected on the touch screen, and when the continuous multi-point touch is detected, corresponds to the continuous multi-point touch. And a symbol recognition unit for searching for a symbol command to execute a symbol command according to the found symbol command with respect to the selected file.

The present invention provides an apparatus and method for intuitive file management in a terminal touch screen, thereby increasing space utilization in a space-limited miniature terminal touch screen, and at the same time reducing the time or the number of clicks required for file management. There is an advantage. In particular, by drawing a simple symbol on the terminal touch screen, various functions (e.g., Copy & Paste, Delete, Move, Shift & Ctrl & Cancel keys, etc.) that were available only on the PC without a mouse or multi-touch are specified. Functions such as viewing a page or menu, transferring files, arranging specific icons, etc.) can be easily used on a terminal. Currently, there is a variety of user interfaces (UIs) in the desire to miniaturize the terminal and the desire to make the screen large, but there are not many UI buttons that are not subject to space constraints in both cases. If the screen is small, there is not enough space to display the menu or keypad. If the screen is large, the user may experience inconvenience due to the position shift when selecting the menu due to the large difference between the current intuitive click position and the next click position. have. However, utilizing the touch screen using the symbol recognition according to the present invention can not only overcome the spatial constraints on the menu, but is also very convenient for the user to use intuitively. You can also easily combine new execution instructions with a combination of symbols. In addition, the file management function in the terminal which is becoming a PC will become an increasingly important function. Therefore, using the touch symbol command according to the present invention can reduce the effort to learn by pressing a new menu every time a new purchase or change of the terminal, there is an advantage that can easily create, copy, delete, move files.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, an apparatus and method for intuitive file management in a terminal touch screen will be described.

1 is a block diagram showing an apparatus configuration of a mobile communication terminal according to the present invention.

As shown, the mobile communication terminal includes a control unit 100, a touch screen unit 102, a touch screen input calculation unit 104, a symbol recognition unit 106, and a symbol database 108.

Referring to FIG. 1, the controller 100 performs a communication and control role between each module unit.

The touch screen unit 102 is responsible for the touch screen input through the user's screen touch and the graphic screen output through the touch screen.

The touch screen input calculator 104 calculates touch coordinates according to the detected screen touch when a touch screen input is detected, that is, when a screen touch is detected. As a general method of calculating the touch coordinates, when a screen touch is detected, a method of calculating the positions of the X and Y axes as the frequency change value, and changing or charging the cap at the reference value before the change, respectively. There is a method of using the speed difference, a method of calculating the center of gravity of pressure, position or capacitance.

The symbol recognition unit 106 selects a file in an area where the one-point touch is detected by using touch coordinates calculated according to one-point touch on the touch screen. In this case, when the one-point touch holding time is longer than the first reference time, the symbol recognition unit 106 converts the selected file into a movable state. Alternatively, when one point touch is detected again for the second reference time in the same area as the detected area, the symbol recognition unit 106 opens the selected file. Alternatively, when a continuous multipoint touch is detected for a third reference time over the same area or another area as the detected area, the symbol recognition unit 106 checks whether the continuous multipoint touch is a symbol touch, and the symbol touch At the moment, execute the symbol command. Here, the symbol recognition unit 106 recognizes a symbol command according to the symbol touch, searches for and executes a symbol command according to the recognized symbol command with reference to the symbol database 108. If the continuous multi-point touch is not a symbol touch, the symbol recognition unit 106 selects a file included in the multi-point area where the continuous multi-point touch is detected.

The symbol database 108 stores symbol commands according to symbol commands.

2 is a flowchart illustrating a file management method including execution of a touch symbol command using a touch screen in a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in step 201, the terminal waits for a touch screen input according to a user's screen touch, and in step 203, the terminal determines whether a single point touch on the touch screen is detected. When the one-point touch is detected, the terminal temporarily selects a file included in an area where the one-point touch is detected in step 205. Alternatively, the cursor may be moved to a file included in an area where the one-point touch is detected, and the cursor may be moved by touching one point in another area again. On the other hand, when the single point touch is not detected, the terminal returns to step 201 and repeats the following steps.

In step 207, the terminal determines whether the one-point touch holding time is longer than the first reference time, and when the one-point touch holding time is longer than the first reference time, that is, one point on the touch screen is touched longer than a specific time. In step 209, the selected file is converted into a movable state. Here, the file converted into the movable state may be moved in a direction in which the user touches.

On the other hand, when the one-point touch holding time is not longer than the first reference time in step 207, the terminal determines whether one-point touch is detected again in the same area as the detected area during the second reference time in step 211. When one point touch is detected again in the same area as the detected area in step 211, the terminal opens the selected file in step 213.

On the other hand, when the single point touch is not detected again in the same area as the detected area in step 211, the terminal performs continuous multi-point touch over the same area or another area over the detected area for the third reference time in step 215. Check whether it is detected. When the continuous multipoint touch is not detected, the terminal returns to step 207 and repeats the following steps.

On the other hand, when the continuous multipoint touch is detected in step 215, the terminal checks whether the continuous multipoint touch is a symbol touch in step 217, and proceeds to step 219 to execute the corresponding symbol command when the symbol touch is performed. do. That is, the terminal recognizes the symbol command according to the symbol touch, searches for and executes the symbol command according to the recognized symbol command in a symbol database.

In the symbol database, as shown in Table 1 below, a symbol command and a function thereof, that is, a symbol command are stored.

Symbol instruction function a Ctrl on PC. However, when you select a file, you can continue to select the file you want after typing a and entering another symbol command without having to keep pressing it. Entering a1 means all to select all files on the touch screen. b Normally back function. If a number is entered immediately after b, the number is reversed. ex) b3, b15, etc. 1. Flips back through pages 2. Zooms in 3. Can be used as a reverse function, depending on the menu or program being used. It can work as a function. For example, when a book is currently displayed, the function of b may be a function of turning a page backward, and when the current map is displayed, the function of b may be an enlargement function, and the current music If b is being played, the function of b may be a rewind function. f Generally forward function. If a number is entered immediately after f, it is forwarded by that amount. For example, f4, f5, etc. 1. A page forward function 2. A zoom out function 3. It can be used as a forward rewind function, etc. It can operate as a different function according to the menu or program currently used as shown in b. h Go to Home (go to first page) c Copy function on PC. Copies the selected file. p Paste function on PC. Paste the selected file. v Cut function / Move function on PC. Move the selected file in the desired direction. s Shift function on PC. However, when selecting a file, if you select the first file and the last file, all files in between are selected without having to continue to enjoy it. Or press s and draw a picture to select all the files in it. o This function replaces the right button of a mouse and is used to view a selectable menu or function. d Generally delete function. You can delete selected files one by one or arbitrarily. z Cancel function. 1. Cancel input function: Cancel the selected file or command. 2. Revert function: Press z after deleting to restore the file. n meaning next, function as opposed to z (revival function) t Transmit function to send a file to the other party through local area communication 1. tb for transmission via Bluetooth 2. tz for transmission with zigbee (tz) 3. th for transmission to human body communication 4. th over USB (Universal Serial Bus) In case of tu 5. In case of transmission by UWB (Ultra Wide Band) tw 6. In case of transmission by Infrared Data Association (IrDA), communication execution command can be given by tr. q Exit function r Receive function for receiving a file from the other party through local area communication. When the data is sent automatically, ok can be accepted and ready or executed. 1 Received by Bluetooth rb 2. Received by Zigbee (rzgbee) rz 3. Received by human body communication rh 4. Received by USB ru 5. Received by UWB rw 6. Received by infrared communication In this case, communication command can be given by sr. w Icon sorting function. wd (date order), wn (name order), wc (format order), etc.

Here, in the PC, the user could easily use the desired function using the mouse, but in the touch screen, the user could not easily use the desired function due to the absence of a proper mouse. However, using various symbol commands as shown in Table 1, the user can intuitively and quickly execute a desired function without a mouse.

Here, an execution example of a symbol command according to a symbol touch will be described with reference to FIG. 3. First, when a user selects a file, for example, file '1' (a in FIG. 3) and then inputs a symbol 'a' (b in FIG. 3), the terminal is assigned to the <Table 1>. The command of the symbol 'a' is executed. Here, the symbol 'a' is a function similar to the ctrl key + left mouse click of a PC, but there is no need to keep pressing when selecting a file. You can freely select any file you want until another symbol is entered. In FIG. 3, after the user inputs the symbol 'a', files '1', '5', '14' and '18' are continuously selected (c in FIG. 3), and the symbol 'd' is selected. FIG. 3D shows the execution of deleting the consecutively selected files '1', '5', '14', and '18' all at once (e) in FIG. 3.

In contrast, in step 217, when the continuous multi-point touch is not a symbol touch, the terminal selects a file included in the multi-point area where the continuous multi-point touch is detected in step 221. That is, by connecting the first point and the last point of the continuous multi-point left and right, up and down, to generate a virtual rectangle having a vertex facing the first point and the last point, and to the coordinates included in the area of the generated rectangle Select all corresponding files.

Here, an example of file selection according to a continuous multi-point touch will be described with reference to FIG. 4. First, when a continuous multi-point touch is detected by the user (a of FIG. 4), the terminal coordinates of the file '1', the first point of the continuous multi-point at which the touch is detected, and the coordinate of the file '9', the last point. By connecting the dots left and right, up and down to create a virtual rectangular area including all files '1' to '9' (Fig. 4b).

Thereafter, the terminal terminates the algorithm according to the present invention.

On the other hand, the embodiment according to the present invention has been described using a file management on the touch screen as an example, in the text working environment such as e-Book, such as a character or a table or a picture forming a text as a single file the present invention Applicable to That is, when a single point touch is detected, the text in the area where the single point touch is detected is selected using touch coordinates calculated according to the single point touch on the touch screen. In this case, when the one-point touch holding time is longer than the first reference time, the selected text may be converted into a movable state. Alternatively, when a continuous multipoint touch is detected for a third reference time over the same area or another area as the detected area, it is determined whether the continuous multipoint touch is a symbol touch, and when the symbol touch is executed, a corresponding symbol command is executed. When the continuous multi-point touch is not a symbol touch, the text elements included in the multi-point area where the continuous multi-point touch is detected may be selected.
