Although the present description is directed to a terminal depicted in
Referring now to
At step 210, the terminal 100 determines whether or not a touch input is detected.
The terminal 100 can detect more than one touch input made sequentially or simultaneously. According to the implementation, the terminal 100 can be configured to detect different types of touch, such as a proximity-based input or pressure-based input as well as the touch-based input. Therefore the term touch is broad as detecting relatively-close contact by a finger or detectable stylus that can be detected by a proximity sensor can be considered to constitute touch.
If a touch is detected at step 210, then at step 220 the terminal 100 selects an object.
The terminal 100 can be configured to determine the position where on the display the touch is made. For example, the terminal 100 can determine 2-dimensional or 3-dimensional coordinates of the position wherein the touch is made on the screen. Furthermore, the terminal 100 can be configured to check the pressure, duration, and movement of the touch (e.g. drag, variation of the distance between multiple touch points and movement pattern of the touch).
In addition, the terminal 100 can select at least one object corresponding to the touch input. The terminal 100 can be configured to detect at least one object (141) located at the position where the touch input is made. The object can be any of an icon, a text, an image, a file, a folder, a web content, a web address, and a web link. The terminal 100 can display the selected object in the form of activated, enlarged, contracted, or shaded. The terminal 100 can display the selected object as activated, enlarged, shrunk, or shaded according to the time duration for which the touch input has been maintained.
Referring now to the exemplary case of
In the case that a touch is made and then moved, the terminal 100 displays the movement of the selected object (141) according to the movement. For example, if a touch is detected and moved in a certain direction, the terminal 100 can display the movement of the selected object in the same direction. The terminal 100 can express/display the moving state of the selected object. For example, the terminal 100 can display the selected object with an additional indicator or a visual effect such as vibration, enlargement, shrink, or shade to express that the object is in the movable state.
Next, referring back to the flowchart of
The terminal 100 detects the gesture input in the state where the touch input is maintained. Referring to the exemplary case of
If at step 230, the gesture input is detected, then at step 240 the terminal 100 performs a switching operation.
More particularly, the terminal 100 performs the switching operation corresponds to the detected gesture input. The terminal 100 searches for the switching operation matched to the gesture input and, if the switching is retrieved, performing the corresponding switching operation.
The switching operation may comprise any of a page switching operation, a folder switching operation, a tab switching operation, an application switching operation, and a task switching operation, just to name some non-limiting possibilities.
The page switching operation can be performed such that the current page is switched to another page with the exception of the selected object (141). The page switching operation can be performed across the screen of the display on which a plurality of pages, each having at least one object, are turned one-by-one in response to a user's request. For example, the page switching operation can be performed on the idle mode screen, file or folder list screen, selectable menu list screen, document screen, e-book screen, phonebook screen, etc., just to name a few non-limiting possibilities.
The terminal 100 can perform page switching in such that when the current page has a plurality of objects, with the exception of the selected object, the display is switched to another page in the state where the selected object is fixed by the touch input. In other words, the terminal 100 turns the current page with the non-selected objects (which may include the background image) to the next page on the screen in a horizontal or a vertical direction on the screen while the object selected by the touch input remains at a fixed position on the display. At this time, the page turning direction and the number of page turnings can be determined according to the direction of the gesture (e.g. horizontal or vertical) or the shape of the gesture (e.g. shape of the hand expressing a certain number). According to the page switching operation, the objects of the previously displayed page disappear except for the object being held and the objects of the new page appear on the screen. In the case where there are no other pages corresponding to the gesture input, the terminal 100 may skip turning the page or displays a message, icon, or image notifying that there are no other pages.
Referring to the exemplary case of
As shown in
The folder switching operation comprises navigating between folders based on the file path of the selected object. The folder switching operation can be performed from among files or folders. For example, the folder switching can be performed between folders including documents, images, pictures, e-books, music files, application execution files or shortcut icons, program execution files or shortcut icons, service execution files or shortcut icons.
For example, one can hold or designate a photo and then with a recognized gesture switch among applications, so that the photo can be inserted in an email, text, Facebook, virtually any kind of communication application that permits transmitting images.
The terminal determines the file path of the selected object held corresponding to the touch input. The terminal 100 can move a folder to a higher or lower level folder along the file path, or a previous or a next folder in a folder list. At this time, a decisions as to whether to move the higher or lower folder level folder or whether to previous on next folder on the same level can be determined according to the direction (horizontal or vertical) of the gesture or the shape of the gesture (e.g. shape of the hand indicating a certain number). According to the folder switching, the objects of the old folder disappear and the objects of the new folder appear on the screen. In the case that there is no other folder corresponding to the gesture input, the terminal 100 skips the folder switching operation or display a message, icon, or image notifying that there is no other folder.
Referring now to the exemplary case of
The tab switching operation comprises navigating between tabs representing respective applications or programs. The tab switching operation can be performed among tabs of the web browser, menu window, e-book, and/or document viewer applications or programs.
The terminal 100 can hold an object corresponding to a touch input and performing the tap switching operation. In other words, the terminal 100 can move the current tab or at least one object included in the current tab in a horizontal or vertical direction relative to another tab or to be placed in another tab. At this time, the tab switching direction and the number of switching operations can be determined according to the direction (horizontal or vertical) or the shape of the gesture. According to the tab switching operation, the objects of a tab disappear and other objects of another tab appear on the screen. In the case that there are no other tabs corresponding to the gesture input, the terminal 100 skips the tab switching operation and displays a message, icon, or image notifying that there is no target tab.
Referring to the exemplary case of
The application or task switching operation comprises a switching between execution screens of the application or tasks for moving a selected object. The application or task switching can be performed from among the different applications or tasks predetermined by the user or terminal manufacturer, or from among the applications or tasks that are currently running. The terminal 100 receives and stores a list of the switching-available applications or tasks that are provided by the user or the terminal manufacturer. The terminal 100 identifies the currently running applications or tasks and performs the switching operation based on the preferences, usage frequencies, and operation times of the respective applications or tasks. The application or task can be any of a messaging, SMS, email, memo, and call application or task, just to name some non-limiting possibilities.
According to this aspect of the present invention, the terminal 100 performs the application or task switching operation with the objects except for the selected object on the screen while holding the object selected by the touch input. In other words, the terminal 100 moves the objects (which may include the background image) in a horizontal or vertical direction to display another application or task window on the screen while holding the selected object at the position corresponding to the touch input. At this time, the switching direction and the number of switching times can be determined according to the direction (horizontal or vertical) or shape (e.g. shape of the hand symbolizing a certain number) of the gesture input. According to the application or task switching operation, the application or task and the objects belonged thereto disappear and another application or task and objects belonged thereto appear on the screen. In the case where no other applications or tasks are targeted by the gesture input, the terminal 100 displays a message, icon, or image notifying that there is no target application or task for display.
Referring now to the exemplary case of
The terminal 100 displays the object selected, in association with the application or task switching, in the format optimized for the target application or task. The terminal 100 presents a preview image of the selected object in the format optimized for adding, inserting, pasting, and attaching to the target application or task. The terminal 100 displays the object as enlarged, shrunk, rotated, or changed in extension or resolution, or along with a text, image, or icon indicating addition, insertion, paste, or attachment.
Referring now to the exemplary case of
Next, the terminal 100 determines at step 250 whether the touch input is released.
After the execution of the switching operation or if no gesture input is detected, the terminal 100 determines whether a touch input is terminated. It is determined that the touch input is terminated when the touch input detects that the user releases the contact of an input device from the touchscreen of the terminal 100.
If the touch input is not terminated, the terminal repeats the switching operation corresponding to the gesture input detection. If the user releases the contact of the input device from the terminal 100, the switching operation of terminal 100 is then terminated.
If the touch input is not terminated, the terminal 100 repeats the switching operation according to the detection of gesture input.
Otherwise, if the touch input is terminated, the terminal 100 terminates the procedure at step 260.
The termination operations may comprise any of aligning the selected object at a position targeted by the touch input, executing the link of the selected object on the tab of the web browser, and pasting the object onto the application or task execution screen.
