step S31: displaying an object on a display interface, wherein the object can be a folder, an application program, a document and the like;
wherein each object displayed on the display interface has a background color region and a foreground color region.
The position range of each object is defined by the background color region, and therefore the coordinates of the background color region of each object are recorded in the system. The background color region may be a transparent (i.e., colorless) region or a colored region. The background color area is generally square, but may be rectangular or circular or other irregular shapes for individualization.

Step S32: detecting sliding operation on a touch screen, and recording track coordinates of the sliding operation by recording coordinates of each touch point through which the sliding operation passes;
the present embodiment starts object selection when a sliding operation on the touch screen is detected, that is, when the multi-selection operation switch is triggered, so that the complicated step of selecting an object is not required to separately trigger the switch in the prior art.
Step S33: judging whether the recorded coordinates of each touch point fall on a certain icon area or do not fall on any icon area, if the coordinates fall on the certain icon area, taking an object corresponding to the icon area as an object selected by the operation sliding, and if not, taking the object as the object selected by the operation sliding; and when the relation between the coordinates of all the touch points and the icon area is judged, all the obtained selected objects are the objects selected by the sliding operation.
Further, in step S32, the sliding operation is a continuous sliding operation, or may be an intermittent sliding operation in which each intermittent time does not exceed a predetermined time. The preset time can be set by a system or a user according to the operation habit of the user.

Preferably, in step S33, a semi-transparent cover layer is disposed above the icon of the selected object to indicate that the object is selected, so that the user can know the selected object conveniently.
Further, the icon area includes a picture display area for displaying a picture of the icon (refer to a picture of the object shown in fig. 3b, for example, a picture made up of paper and a pen above the text "gwpreset. The system records the coordinates of the picture display area and the coordinates of the character display area. In step S33, when the track coordinate of the sliding operation passes through one of the picture display area and the text display area, the corresponding object may be selected; or when the track coordinate of the sliding operation passes through the picture display area and the character display area, the corresponding object is selected; compared with the former selection mode, the latter selection mode can effectively avoid the object from being selected by mistake and improve the accuracy of selection.
Preferably, in step S32, the track of the sliding operation is displayed in the form of a colored line to facilitate the user to recognize the track path. As shown in fig. 3B, taking the finger sliding operation and the continuous sliding as an example, the finger of the user starts to slide from point a, the continuous sliding is released to point B, and the trajectory AB (which may be a red trajectory) passes through the icon area of the object 1 (Visual folder in fig. 3B), the icon area of the object 2 (GoldWave batch file in fig. 3B), and the icon area of the object 3 (GWSpeed 64 dynamic link library file in fig. 3B), so that the object 1 (Visual folder in fig. 3B), the object 2 (GoldWave batch file in fig. 3B), and the object 3 (GWSpeed 64 dynamic link library file in fig. 3B) are the objects selected by the current sliding operation.

The background color region may be a transparent (i.e., colorless) region or a colored region. The background color area is generally square, but may be rectangular or circular or other irregular shapes for individualization.

The foreground color area is located within the range of the background color area, and generally, for aesthetic reasons, the foreground color area is located at the center position inside the background color area as much as possible.
The detection module is used for detecting the sliding operation on the touch screen and recording the track coordinate of the sliding operation by recording the coordinate of each touch point through which the sliding operation passes;
the present embodiment starts object selection when a sliding operation on the touch screen is detected, that is, when the multi-selection operation switch is triggered, so that the complicated step of selecting an object is not required to separately trigger the switch in the prior art.
The determining module is used for judging whether the recorded coordinates of each touch point fall on an icon area or do not fall on any icon area, if the coordinates fall on the icon area, an object corresponding to the icon area is used as an object selected by the operation in a sliding mode, and if the coordinates do not fall on the icon area, the object corresponding to the icon area is used as the object selected by the operation in the sliding mode; and when the relation between the coordinates of all the touch points and the icon area is judged, all the obtained selected objects are the objects selected by the sliding operation.
Further, the sliding operation in the detection module may be a continuous sliding operation, or may be an intermittent sliding operation in which each intermittent time does not exceed a predetermined time. The preset time can be set by a system or a user according to the operation habit of the user.
When the sliding operation is a continuous sliding operation, if the sliding operation is not detected, the end of the current sliding operation is judged, and the track coordinates of the sliding operation are recorded.
When the sliding operation is the intermittent sliding operation, when the sliding operation is not detected and the intermittent sliding operation with the interval time larger than the preset time does not occur, judging that the current sliding operation is finished, and recording the track coordinate of the sliding operation; when the intermittent sliding operation with the interval time larger than the preset time occurs in the sliding operation, the end of the sliding operation is judged, the sliding operation with the interval time larger than the preset time is an effective sliding operation, and the track coordinate of the effective sliding operation is recorded.
Preferably, in the determining module, a semi-transparent covering layer is arranged above the icon of the selected object to indicate that the object is selected, so that a user can know the selected object conveniently.
Further, the icon area includes a picture display area for displaying a picture of the icon (refer to a picture of the object shown in fig. 3b, for example, a picture made up of paper and a pen above the text "gwpreset. The system records the coordinates of the picture display area and the coordinates of the character display area. The determining module may determine that the corresponding object is selected when the track coordinate of the sliding operation passes through one of the picture display area or the character display area; or when the track coordinate of the sliding operation passes through the picture display area and the character display area, determining that the corresponding object is selected; compared with the former selection mode, the latter selection mode can effectively avoid the object from being selected by mistake and improve the accuracy of selection.
Preferably, in the detection module, the track of the sliding operation is displayed in a colored line manner, so that a user can conveniently recognize the track path. As shown in fig. 3B, taking the finger sliding operation and the continuous sliding as an example, the finger of the user starts to slide from point a, the continuous sliding is released to point B, and the trajectory AB (which may be a red trajectory) passes through the icon area of the object 1 (Visual folder in fig. 3B), the icon area of the object 2 (GoldWave batch file in fig. 3B), and the icon area of the object 3 (GWSpeed 64 dynamic link library file in fig. 3B), so that the object 1 (Visual folder in fig. 3B), the object 2 (GoldWave batch file in fig. 3B), and the object 3 (GWSpeed 64 dynamic link library file in fig. 3B) are the objects selected by the current sliding operation.
In embodiment 1 of the present invention, the object selected by the slide operation is determined by comparing the relationship between the coordinates of each touch point through which the slide operation passes and the icon area of the object on the display interface.
Example 2:
an embodiment of the present invention provides a method for selecting an object on a touch screen, as shown in fig. 4a, the method includes the following steps:
step S41: displaying an object on a display interface, wherein the object can be a folder, an application program, a document and the like;
wherein each object displayed on the display interface has a background color region and a foreground color region.
The position range of each object is defined by the background color region, and therefore the coordinates of the background color region of each object are recorded in the system. The background color region may be a transparent (i.e., colorless) region or a colored region. The background color area is generally square, but may be rectangular or circular or other irregular shapes for individualization. The color and shape of the background color region of each object may be set individually or may be set collectively. The background color areas of two adjacent objects can be connected or have intervals.
The position range of the icon of each object is defined by the foreground color region, and the position range of the icon of each object is formed with the icon region of each object, so that the coordinates of the foreground color region of each object and the coordinates of the icon region are recorded in the system. The foreground color area is located within the range of the background color area, and generally, for aesthetic reasons, the foreground color area is located at the center position inside the background color area as much as possible.
Step S42: detecting sliding operation on a touch screen, and recording track coordinates of the sliding operation;
the present embodiment starts object selection when a sliding operation on the touch screen is detected, that is, when the multi-selection operation switch is triggered, so that the complicated step of selecting an object is not required to separately trigger the switch in the prior art.
Step S43: determining the object selected by the sliding operation according to the relationship between the track coordinate of the sliding operation and the icon area of each object on the display interface and whether the track coordinate forms a closed curve in the background color area of a certain object, wherein if the track coordinate of the sliding operation falls into the icon area of the certain object and the track coordinate does not form the closed curve in the background color area of the object, the object is the object selected by the sliding operation, otherwise, the object is not selected.
In embodiment 2 of the present invention, a closed curve is formed in a background color area of an object by determining a track coordinate, and the object is determined to be an object erroneously selected by the current sliding operation. In this way, the object that the user selected by mistake can be deselected.
Of course, although the present embodiment limits the closed curve to be formed in the background color region of the certain object to provide a larger operation range for the user, the implementation of limiting the closed curve to be formed in the icon region of the certain object is not excluded.
Further, in step S42, the sliding operation is a continuous sliding operation, or may be an intermittent sliding operation in which each intermittent time does not exceed a predetermined time. The preset time can be set by a system or a user according to the operation habit of the user.
When the sliding operation is a continuous sliding operation, if the sliding operation is not detected, the end of the current sliding operation is judged, and the track coordinates of the sliding operation are recorded.
When the sliding operation is the intermittent sliding operation, when the sliding operation is not detected and the intermittent sliding operation with the interval time larger than the preset time does not occur, judging that the current sliding operation is finished, and recording the track coordinate of the sliding operation; when the intermittent sliding operation with the interval time larger than the preset time occurs in the sliding operation, the end of the sliding operation is judged, the sliding operation with the interval time larger than the preset time is an effective sliding operation, and the track coordinate of the effective sliding operation is recorded.
In embodiment 2 of the present invention, all the intermittent sliding operations with the interval time within the predetermined time are regarded as effective sliding operations, and the present invention is particularly suitable for occasions where the object in the wrong selection is cancelled. For example, the user may slide within the background color region of the object to be erroneously selected to form a closed curve, or slide within the foreground color region of the object to be erroneously selected to form a closed curve, or slide within the icon region of the object to be erroneously selected to form a closed curve. Embodiment 2 of the present invention may be implemented in combination with embodiment 1 or may be implemented separately.
Preferably, in step S43, a semi-transparent cover layer is disposed above the icon of the selected object to indicate that the object is selected, so that the user can know the selected object conveniently.
Further, the icon area includes a picture display area for displaying a picture of the icon (refer to a picture of the object shown in fig. 3b, for example, a picture made up of paper and a pen above the text "gwpreset. The system records the coordinates of the picture display area and the coordinates of the character display area. In step S43, when the track coordinate of the sliding operation passes through one of the picture display area and the text display area, the corresponding object may be selected; or when the track coordinate of the sliding operation passes through the picture display area and the character display area, the corresponding object is selected; compared with the former selection mode, the latter selection mode can effectively avoid the object from being selected by mistake and improve the accuracy of selection.
Preferably, in step S42, the track of the sliding operation is displayed in the form of a colored line to facilitate the user to recognize the track path. As shown in fig. 4B, taking the finger sliding operation and the intermittent sliding operation within the predetermined time as an example, the finger of the user starts sliding from point a, continuously slides until point B is released, sliding within the foreground color region of object 2 (the GoldWave batch file in fig. 4 b) within a predetermined time then constitutes a closed curve, at which point, while trace AB (which may be a red trace) passes through the icon area of object 1 (Visual folder in figure 4 b), the icon area of object 2 (GoldWave batch file in figure 4 b) and the icon area of object 3 (GWSpeed 64 dynamic link library file in figure 4 b), however, the selection operation of object 2 (the GoldWave batch file in fig. 4 b) is cancelled, so that object 1 (the Visual folder in fig. 4 b) and object 3 (the GWSpeed64 dynamic link library file in fig. 4 b) are selected objects in the sliding operation.
As shown in fig. 2, a system for selecting an object on a touch screen according to an embodiment of the present invention includes: the device comprises a display module, a detection module and a determination module.
The display module is used for displaying objects on the display interface, wherein the objects can be folders, application programs, documents and the like.
Each object displayed on the display interface has a background color region and a foreground color region.
The position range of each object is defined by the background color region, and therefore the coordinates of the background color region of each object are recorded in the system. The background color region may be a transparent (i.e., colorless) region or a colored region. The background color area is generally square, but may be rectangular or circular or other irregular shapes for individualization. The color and shape of the background color region of each object may be set individually or may be set collectively. The background color areas of two adjacent objects can be connected or have intervals.
The position range of the icon of each object is defined by the foreground color region, and the position range of the icon of each object is formed with the icon region of each object, so that the coordinates of the foreground color region of each object and the coordinates of the icon region are recorded in the system. The foreground color area is located within the range of the background color area, and generally, for aesthetic reasons, the foreground color area is located at the center position inside the background color area as much as possible.
The detection module is used for detecting sliding operation on the touch screen and recording track coordinates of the sliding operation;
the present embodiment starts object selection when a sliding operation on the touch screen is detected, that is, when the multi-selection operation switch is triggered, so that the complicated step of selecting an object is not required to separately trigger the switch in the prior art.
The determining module is used for determining the object selected by the sliding operation according to the relationship between the track coordinate of the sliding operation and the icon area of each object on the display interface and whether the track coordinate forms a closed curve in the background color area of a certain object, if the track coordinate of the sliding operation falls into the icon area of a certain object and the track coordinate does not form a closed curve in the background color area of the object, the object is the object selected by the sliding operation, otherwise, the object is not selected.
In embodiment 2 of the present invention, a closed curve is formed in a background color region of an object by the track coordinate, and the object is determined to be an object erroneously selected by the current sliding operation. In this way, the object that the user selected by mistake can be deselected.
Of course, although the present embodiment limits the closed curve to be formed in the background color region of the certain object to provide a larger operation range for the user, the implementation of limiting the closed curve to be formed in the icon region of the certain object is not excluded.
Further, the sliding operation in the detection module may be a continuous sliding operation, or may be an intermittent sliding operation in which each intermittent time does not exceed a predetermined time. The preset time can be set by a system or a user according to the operation habit of the user.
When the sliding operation is a continuous sliding operation, if the sliding operation is not detected, the end of the current sliding operation is judged, and the track coordinates of the sliding operation are recorded.
When the sliding operation is the intermittent sliding operation, when the sliding operation is not detected and the intermittent sliding operation with the interval time larger than the preset time does not occur, judging that the current sliding operation is finished, and recording the track coordinate of the sliding operation; when the intermittent sliding operation with the interval time larger than the preset time occurs in the sliding operation, the end of the sliding operation is judged, the sliding operation with the interval time larger than the preset time is an effective sliding operation, and the track coordinate of the effective sliding operation is recorded.
In embodiment 2 of the present invention, all the intermittent sliding operations with the interval time within the predetermined time are regarded as effective sliding operations, and the present invention is particularly suitable for occasions where the object in the wrong selection is cancelled. For example, the user may slide within the background color region of the object to be erroneously selected to form a closed curve, or slide within the foreground color region of the object to be erroneously selected to form a closed curve, or slide within the icon region of the object to be erroneously selected to form a closed curve. The present invention can be implemented in combination with embodiment 1 or separately in embodiment 2.
Preferably, in the determining module, a semi-transparent covering layer is arranged above the icon of the selected object to indicate that the object is selected, so that a user can know the selected object conveniently.
Further, the icon area includes a picture display area for displaying a picture of the icon (refer to a picture of the object shown in fig. 3b, for example, a picture made up of paper and a pen above the text "gwpreset. The system records the coordinates of the picture display area and the coordinates of the character display area. The determining module can determine that the corresponding object is selected when the track coordinate of the sliding operation passes through one of the picture display area or the character display area; or when the track coordinate of the sliding operation passes through the picture display area and the character display area, determining that the corresponding object is selected; compared with the former selection mode, the latter selection mode can effectively avoid the object from being selected by mistake and improve the accuracy of selection.
Preferably, in the detection module, the track of the sliding operation is displayed in a colored line manner, so that a user can conveniently recognize the track path. As shown in fig. 4B, taking the finger sliding operation and the intermittent sliding operation within the predetermined time as an example, the finger of the user starts sliding from point a, continuously slides until point B is released, sliding within the foreground color region of object 2 (the GoldWave batch file in fig. 4 b) within a predetermined time then constitutes a closed curve, at which point, while trace AB (which may be a red trace) passes through the icon area of object 1 (Visual folder in figure 4 b), the icon area of object 2 (GoldWave batch file in figure 4 b) and the icon area of object 3 (GWSpeed 64 dynamic link library file in figure 4 b), however, the selection operation of object 2 (the GoldWave batch file in fig. 4 b) is cancelled, so that object 1 (the Visual folder in fig. 4 b) and object 3 (the GWSpeed64 dynamic link library file in fig. 4 b) are selected objects in the sliding operation.
