Detailed Description
The mobile terminal comprises a man-machine interface module 101, a user interface management module 102, a central processing unit 103 and a program storage module 104.
And the human-computer interface module 101 is used for detecting the operation of the user on the touch display screen and displaying the desktop on the touch display screen, and is also used for calling the picture and the interface of the program storage module, displaying the corresponding interface on the screen and waiting for the user operation. The function of the module is the same as that of the man-machine interface module in the prior art.
And the user interface management module 102 is configured to control the human-machine interface module to display the target operation area according to an instruction of the central processing module, and is further configured to support an enlargement display, a reduction display, or a translation display of all desktops, and an enlargement display, a reduction display, or a translation display of a local desktop.
The central processing module 103 is configured to acquire a touch screen event of a user on the touch display screen through the human-computer interface module, determine a target operation area according to the touch screen event, and control the user interface management module to perform enlargement display, reduction display, or translation display on the target operation area, where the target operation area is a whole desktop or a local desktop.
The program storage module 104 is used for storing pictures, data, menus and display interfaces required by the mobile phone; in addition, an operating system, application functions, data files and the like of the mobile phone are also stored. The function of this module is the same as that of the program storage module of the prior art.
The user enables the mobile terminal to know the target operation area of the user by operating the touch screen.
When the user presses the position of the non-control on the display screen for a long time, the target operation area representing the user is the whole desktop. After detecting a long-press operation in a touch event through the human-computer interface module 101, the central processing module 103 uses the entire desktop as a target operation area selected by a user when judging that a starting point of the long-press operation corresponds to a non-control position on the display screen.
When the user presses the control position on the display screen for a long time, the target operation area representing the user is the control. After detecting a long-press operation in a touch screen event through the human-computer interface module 101, the central processing module 103 takes a control area corresponding to a control position as a target operation area selected by a user when judging that an initial point of the long-press operation corresponds to the control position on the display screen.
When the user moves on the display screen to indicate a closed area, for example, an area enclosing a plurality of controls, the target operation area of the user is the closed area. The central processing module 103 is further configured to, after detecting that a closed region is formed by history points in a touch event through the human-computer interface module, take the corresponding closed region on the desktop as a target operation region selected by a user.
After determining the target operation area, the central processing module 103 displays the target operation area in a selected state. The display of the selected state may be performed in various ways, such as displaying a border at the edge of the target operation area, displaying the target operation area in a certain color or transparent effect, and indicating other ways of the target operation area.
The modes of the user for zooming the target operation area by operating the touch screen include the following two modes.
In a first mode, after determining a target operation area, the central processing module 103 displays a zoom-out control and a zoom-in control on the touch display screen through the user interface management module, and after detecting a short-press operation at a position corresponding to the zoom-out control through the human-computer interface module, performs zoom-out display on the target operation area through the user interface management module, and after detecting a short-press operation at a position corresponding to the zoom-in control through the human-computer interface module, performs zoom-in display on the target operation area through the user interface management module.
In the second mode, after the central processing module 103 detects the multi-point opposite movement operation through the human-computer interface module, the target operation area is displayed in a reduced manner corresponding to the stroke length through the user interface management module, and after the multi-point opposite movement operation is detected through the human-computer interface module, the target operation area is displayed in an enlarged manner corresponding to the stroke length through the user interface management module.
The method for zooming the target operation area by translating and zooming the touch screen by the user comprises the following steps: after the central processing module 103 determines a target operation area, and detects a single-point movement operation or a multi-point equidirectional movement operation through the human-computer interface module, the user interface management module performs translation display on the target operation area in the same direction as the movement operation direction and corresponding to the stroke length.
The method for controlling desktop display comprises the following steps: after detecting a touch screen event of a user on a touch display screen, the mobile terminal determines a target operation area according to the touch screen event and performs amplification display, reduction display or translation display on the target operation area, wherein the target operation area is a whole desktop or a local desktop.
When a user presses a non-control position on the display screen for a long time, the whole desktop is taken as a target operation area selected by the user. After detecting a long-time pressing operation in a touch screen event, the mobile terminal takes the whole desktop as a target operation area selected by a user when judging that the starting point of the long-time pressing operation corresponds to a non-control position on a display screen;
when the user presses the position of the control on the display screen for a long time, the control is taken as the target operation area selected by the user. After detecting a long-time pressing operation in a touch screen event, the mobile terminal judges that the starting point of the long-time pressing operation corresponds to a control position on a display screen, and takes a control area corresponding to the control position as a target operation area selected by a user;
the user uses a finger to stroke the closed area on the display screen, and the closed area is used as a target operation area selected by the user. After the mobile terminal detects that history points in a touch screen event form a closed area, taking the corresponding closed area on the desktop as a target operation area selected by a user.
And after the mobile terminal determines a target operation area, displaying the target operation area as a selected state. The display of the selected state may be performed in various ways, such as displaying a border at the edge of the target operation area, displaying the target operation area in a certain color or transparent effect, and indicating other ways of the target operation area.
The modes of the user for zooming the target operation area by operating the touch screen include the following two modes.
In the first mode, after the mobile terminal determines a target operation area, a zoom-out control and a zoom-in control are displayed on a touch display screen, the target operation area is displayed in a zoom-out mode after a short-press operation is detected at a position corresponding to the zoom-out control, and the target operation area is displayed in a zoom-in mode after the short-press operation is detected at a position corresponding to the zoom-in control;
in the second mode, the user can use two fingers to move in opposite directions on the display screen to indicate that the target operation area is desired to be reduced, or use two fingers to move in opposite directions on the display screen to indicate that the target operation area is desired to be enlarged. And after detecting the multi-point reverse movement operation, the mobile terminal performs zooming-out display corresponding to the stroke length on the target operation area, and performs zooming-in display corresponding to the stroke length on the target operation area.
The user may indicate the direction in which the user wishes to pan by swiping in the target direction with one finger, or by swiping in the same direction with multiple fingers. And after detecting the single-point movement operation or the multi-point equidirectional movement operation, the mobile terminal performs translation display on the target operation area in the same direction as the movement operation direction and corresponding to the stroke length.
According to the scheme, the whole or part of the desktop is dragged and dropped or zoomed through an operation mode of the touch screen, so that a user can use the touch type terminal more conveniently and quickly, and a new experience degree of the user is provided.
As shown in fig. 2, the central processing unit converts the operation of the user on the interface into the operation of the application corresponding to the graphic management system, calls the corresponding interface management module, and refreshes the display result to the screen buffer and displays the display result on the display screen.
