Description

METHOD AND APPARATUS FOR SELECTING OBJECTS

RELATED APPLICATION

This application claims priority to Chinese Patent Application Serial No. 201310518421.9, entitled “Method and Apparatus for Selecting Objects, ” filed October 28, 2013, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application generally relates to the field of computer technology, and more particularly to a method and related apparatus for selecting objects displayed in a user interface.

BACKGROUND

With the popularity and wide use of mobile terminal devices, more and more application programs are developed for mobile terminal devices, especially mobile terminal devices equipped with a touchscreen. Some application programs developed for mobile terminal devices require a user to select (e.g. , use the user’s finger) objects displayed in a user interface. According to some known object-selecting methods, in order to select multiple objects, a user is typically required to perform multiple selections to select each object individually. However, due to limited distances between the multiple objects displayed in the user interface, such known object-selecting methods are difficult to perform and prone to mistakes, especially for mobile terminal devices equipped with a touchscreen. As a result, the known object-selecting methods potentially prolong the process of selection for the user and increase power consumption for the mobile terminal devices.

Thus, a need exists for a method and related apparatus that can provide a method for efficiently and accurately selecting multiple objects displayed in a user interface of a mobile terminal device.

SUMMARY

The above deficiencies associated with the known object-selecting methods may be reduced or eliminated by the techniques described herein.

In some embodiments, an apparatus includes one or more processors, and memory storing one or more programs to be executed by the one or more processors. The one or more programs include instructions for receiving information of a first slide operation performed on a user interface of the apparatus. The information of the first slide operation indicates a path of the first slide operation from a starting point to an end point on the user interface. The one or more programs include instructions for determining a set of objects from a group of objects displayed in the user interface based on the information of the first slide operation and location information of the group of objects. Each object from the set of objects is associated with at least a portion of the path of the first slide operation.

The one or more programs also include instructions for changing a selection status of a first object from the set of objects from a first selection status to a second selection status. The first selection status and the second selection status are different. The first object is associated with the starting point of the first slide operation. In some instances, the selection status of each object from the group of objects is either the first selection status or the second selection status. The one or more programs further include instructions for updating a selection status of each remaining object from the set of objects such that the updated selection status of each remaining object is the second selection status.

In some instances, the information of the first slide operation includes coordinates of the path of the first slide operation on the user interface. In such instances, the instruction for determining includes determining the set of objects based on whether the coordinates correspond to the location of the set of objects displayed in the user interface. In some instances, the information of the first slide operation includes at least one coordinate of the starting point and at least one coordinate of the end point, where the at least one coordinate of the starting point corresponds to the location of the first object, and the at least one coordinate of the end point corresponds to the location of an object (the first object or another object) from the set of objects.

In some instances, the instruction for determining includes determining the set of objects based on 1) whether vertical coordinates of the path of the first slide operation correspond to the location of the set of objects independent of horizontal coordinates of the path of the first slide operation, or 2) whether horizontal coordinates of the path of the first slide operation correspond to the location of the set of objects independent of vertical coordinates of the path of the first slide operation.

In some instances, the one or more programs include instructions for receiving information of a second slide operation performed on the user interface. The information of the second slide operation indicates a path of the second slide operation from a starting point of the second slide operation to an end point of the second slide operation on the user interface. In such instances, the one or more programs include instructions for determining, based on the information of the second slide operation, whether the starting point of the second slide operation corresponds to an object from the group of objects and whether the end point of the second slide operation corresponds to an object from the group of objects.

Furthermore, the one or more programs include instructions for, if the starting point of the second slide operation is determined to correspond to an object from the group of objects and the end point of the second slide operation is determined not to correspond to any object from the group of objects, updating the selection status of the group of objects such that the updated selection status of each object from the group of objects is a predefined selection status. In some instances, the predefined selection status is one of the first selection status and the second selection status.

In some instances, the information of the second slide operation includes at least one coordinate of the starting point of the second slide operation and at least one coordinate of the end point of the second slide operation. In such instances, the instruction for determining includes determining whether the at least one coordinate of the starting point of the second slide operation corresponds to the location of objects from the group of objects, and whether the at least one coordinate of the end point of the second slide operation corresponds to the location of objects from the group of objects.

In some embodiments, an apparatus includes one or more processors, and memory storing one or more programs to be executed by the one or more processors. The one or more programs include instructions for receiving information of a touch operation performed on a user interface of the apparatus. The information of the touch operation indicates a number of touch points of the touch operation. The one or more programs include instructions for determining whether the number of touch points is greater than a threshold number of touch points.

Furthermore, the one or more programs include instructions for, if the number of touch points is determined to be greater than the threshold number, identifying a set of objects from a group of objects displayed in the user interface and then performing a predefined operation on each object from the set of objects without performing the predefined operation on any object excluded from the set of objects. Each object from the set of objects is in a first selection status, and each object excluded from the set of objects is in a second selection status different from the first selection status. In some instances, performing the predefined operation on each object from the set of objects includes changing the location of that object on the user interface. In some instances, the threshold number of touch points is one.

In some instances, the information of the touch operation indicates a location of the touch operation on the user interface. The one or more programs further comprise instructions for, if the number of touch points is determined to be less than or equal to the threshold number, identifying an object from the group of objects based on the location of the touch operation and location information of the group of objects, and then changing the selection status of the identified object. The location of the touch operation is associated with the location of the identified object. In some instances, a horizontal coordinate of the location of the touch operation corresponds to a vertical coordinate of the identified object, and a vertical coordinate of the location of the touch operation does not correspond to any vertical coordinate of the identified object.

In some embodiments, a non-transitory computer readable storage medium stores one or more programs including instructions for execution by one or more processors. The instructions, when executed by the one or more processors, cause the processors to perform the method for selecting objects displayed in a user interface of an apparatus as described above.

Various advantages of the present application are apparent in light of the descriptions below.

DESCRIPTION OF EMBODIMENTS

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject matter presented herein. But it will be apparent to one skilled in the art that the subject matter may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

In order to make the objectives, technical solutions, and advantages of the present application comprehensible, embodiments of the present application are further described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart illustrating a method 100 performed at an apparatus for selecting objects displayed in a user interface of the apparatus in accordance with some embodiments. The apparatus performing the method 100 can be any type of electronic device configured to present, to a user of the apparatus, a user interface where one or more objects are displayed. The user can operate the apparatus to manipulate a position of each object that is displayed in the user interface of the apparatus. In some embodiments, such an apparatus can be, for example, a cellular phone, a smart phone, a mobile Internet device (MID) , a personal digital assistant (PDA) , a tablet computer, an e-book reader, a laptop computer, a handheld computer, a desktop computer, a wearable device, a MP3 player (Moving Picture Experts Group Audio Layer III) , a MP4 (Moving Picture Experts Group Audio Layer IV) player, and/or any other personal electronic device. In some embodiments, the apparatus can be referred to as, for example, a client device, a mobile device, a user device, a terminal device, a portable device, and/or the like.

In some embodiments, the apparatus includes a display device configured to display the user interface including visual representations (e.g. , an icon, an image, a figure, a symbol, etc. ) of one or more objects. Such a display device can be any device configured to display a user interface such as, for example, a screen, a monitor, a touch screen, a projector, and/or the like.

In some embodiments, when an application program (e.g. , a software application) of the apparatus is executed at the apparatus, the apparatus is configured to display the visual representations of the objects on the user interface. Such an application program can be, for example, a game (e.g. , a card game, a board game, etc. ) or any other type of application. Such an object can be, for example, an icon, a list, a figure, an image, a picture, a text block, a table, and/or the like. For example, as shown in FIGS. 1a, 2a, 3a and 3b described below, the application program can be a card game and the objects can be cards used in the card game.

In some embodiments, the apparatus performing the method 100 can be operatively connected to and communicate with other network devices (e.g. , another apparatus similar to the apparatus performing the method 100) via, for example, one or more networks (e.g. , the Internet) . Structure, modules and components of the apparatus are further shown and described below with respect to FIGS. 5a, 5b and 6. In some embodiments, the user operating the apparatus can be any person (potentially) interested in using the application game. Such a person can be, for example, a player of a card game.

The apparatus performing the method 100 includes one or more processors and memory. In some embodiments, the method 100 is implemented using instructions or code of the application program that are stored in a non-transitory computer readable storage medium of the apparatus and executed by the one or more processors of the apparatus. In such embodiments, the application program is associated with displaying and manipulating visual representations of objects on the user interface of the apparatus. Instructions of the application program are stored in and/or executed at the apparatus. As a result of such an application program being executed, the method 100 is performed to manipulate the visual representations of the objects (simplified as “object” herein) displayed in the user interface. As shown in FIG. 1, the method 100 includes the following steps.

At S101, the apparatus receives information of a slide operation performed on the user interface of the apparatus. The received information of the slide operation indicates a path of the slide operation from a starting point to an end point on the user interface. In some embodiments, such a slide operation can be performed by the user using, for example, a finger of the user, an input device of the apparatus (e.g. , a mouse, a keyboard, a touch pen stylus, etc. ) , or any other suitable input method.

In some embodiments, the slide operation is performed within an operable area of the user interface. Such an operable area of the user interface can include, for example, any area of the user interface that is not occupied by a predefined icon (e. g., with a specific given function) such as, for example, a button to submit a result, a button for going to a next page, an text message block showing an instruction, and/or the like. In some embodiments, the operable area of the user interface includes any area where an object being operated can potentially be. In some embodiments, the operable area of the user interface is defined as any area of the user interface, on which an operation (e.g. , a slide operation, a touch operation, etc. ) is treated as a valid operation on the objects being operated.

In some embodiments, location information of an operation (e.g. , a touch operation, a slide operation, etc. ) performed by the user on the user interface is collected by, for example, one or more monitoring instructions or commands executed at the apparatus. For example, for an iPhone device functioning as the apparatus, UITouches can be used to determine coordinates of a touch point on the user interface. Alternatively, UIGestureRecognizer from the developer tool kit iPhone SDK can also be used to capture location information of a touch point or an operation. For another example, for an Android device, MotionEvent can be used to obtain location information of a touch point or an operation.

To be more specific, for example, when UITouches is used, the operating system of the apparatus (e.g. , an iPhone device) is enabled to capture the following four types of UITouches events (i.e. , touch operation on the user interface) :

1) (void) touchesBegan: (NSSet *) touches withEvent: (UIEvent *) event, which is triggered by the initial contact (e.g. , of a finger) with the screen (e.g. , a touch screen) , and as a result, a starting point of the operation is determined；

2) (void) touchesMoved: (NSSet *) touches withEvent: (UIEvent *) event, which is triggered by a slide operation (e.g. , continuous and moving contact with the screen) performed on the user interface；

3) (void) touchesEnded: (NSSet *) touches withEvent: (UIEvent *) event, which is triggered by disengagement (e.g. , of a finger) of contact with the screen (e.g. , a touch screen) , and as a result, an end point of the operation is determined； and

4) (void) touchesCancelled: (NSSet *) touches withEvent: (UIEvent *) event, which is triggered by sliding (e.g. , of a finger) out of the screen (e.g. , a touch screen) or the operable area of the user interface, and as a result, an end point of the operation is determined.

Additionally, information of a number of touch points occurred during the operation can be captured and recorded. Such information can be used to determine, for example, whether the operation is a single-touch point operation (e.g. , a touch by a single finger) or multiple-touch point operation (e.g. , touches by two fingers) . As shown and described below with respect to FIG. 4, different methods can be performed based on the number of touch points of an operation performed on the user interface.

For another example, when UIGestureRecognize is used (e.g. , on an iPhone device) , a derivative function UIGestureRecognizer can be instantiated and displayed as an object on the user interface, to capture information of operations (particularly, slide operations) performed by the user on the user interface. The following four types of events can be captured by analyzing state value (s) of the UISwipeGestureRecognizer object:

1) a UIGestureRecognizerStateBegan event, which is triggered by the initial contact (e.g. , of a finger) with the screen (e.g. , a touch screen) as part of a slide operation performed on the user interface；

2) a UIGestureRecognizerStateChanged event, which is triggered by a slide operation (e.g. , continuous and moving contact with the screen) performed on the user interface；

3) a UIGestureRecognizerStateEnded event, which is triggered by disengagement (e.g. , of a finger) of contact with the screen (e.g. , a touch screen) ； and

4) a UIGestureRecognizerStateCancelled event, which is triggered by sliding (e. g., of a finger) out of the screen (e.g. , a touch screen) or the operable area of the user interface.

Subsequently, each analyzed state value of the UISwipeGestureRecognizer object can be processed to determine location information of the touch point (s) .

For yet another example, when MotionEvent is used, the operating system of the apparatus (e.g. , an Android device) is enabled to capture the following four types of MotionEvent events (i.e. , touch operation on the user interface) :

1) a MotionEvent. ACTION_DOWN, which is triggered by the initial contact (e. g., of a finger) with the screen (e.g. , a touch screen) , and as a result, a starting point of the operation is determined；

2) a MotionEvent. ACTION_MOVE event, which is triggered by a slide operation (e.g. , continuous and moving contact with the screen) performed on the user interface；

3) a MotionEvent. ACTION_UP, which is triggered by disengagement (e. g., of a finger) of contact with the screen (e.g. , a touch screen) , and as a result, an end point of the operation is determined； and

4) a MotionEvent. ACTION_CANCEL, which is triggered by sliding (e.g. , of a finger) out of the screen (e.g. , a touch screen) or the operable area of the user interface, and as a result, an end point of the operation is determined.

Additionally, similar to the case of UITouches, a getPointerCount () function in the MotionEvent objects can be invoked to capture and record a number of touch points occurred during the operation.

At S102, the apparatus determines a set of objects from a group of objects displayed in the user interface based on the information of the slide operation and location information of the group of objects. Each object from the set of objects is associated with at least a portion of the path of the slide operation. The apparatus can determine the set of objects in various suitable methods based on the information of the slide operation and location information of the group of objects.

In some embodiments, for example, the information of the slide operation includes coordinates of the path of the slide operation on the user interface. In such embodiments, the apparatus can be configured to determine the set of objects based on whether the coordinates correspond to the location of objects from the set of objects displayed in the user interface. Specifically, for example, the information of the slide operation includes at least one coordinate of the starting point and at least one coordinate of the end point. The apparatus can be configured to determine a first object from the group of objects, whose location corresponds to the at least one coordinate of the starting point. Similarly, the apparatus can be configured to determine a second object from the group of objects, whose location corresponds to the at least one coordinate of the end point.

Furthermore, in some embodiments, the apparatus can be configured to determine the set of objects from the group of objects based on vertical coordinates of the path of the slide operation corresponding to the location of objects from the set of objects. Such a determination can be independent of horizontal coordinates of the path of the slide operation. Alternatively, the apparatus can be configured to determine the set of objects from the group of objects based on horizontal coordinates of the path of the slide operation corresponding to the location of objects from the set of objects. Such a determination can be independent of vertical coordinates of the path of the slide operation. In some embodiments, the apparatus can be configured to determine the set of objects from the group of objects using both vertical and horizontal coordinates of the path of the slide operation.

As an example, FIG. 1a is a schematic diagram illustrating a user interface 110 of the apparatus associated with performing the method 100 in FIG. 1. As shown in FIG. 1a, a slide operation is performed on a user interface where a group of cards (i.e. , objects) are displayed. The starting point of the slide operation has a horizontal coordinate X2 and a vertical coordinate (not shown in FIG. 1a) . Similarly, the end point of the slide operation has a horizontal coordinate X3 and a vertical coordinate (not shown in FIG. 1a) . Thus, the slide operation has a range of horizontal coordinates [X2, X3] .

In this example, the determination of a set of cards from the group of cards is based on the horizontal coordinates of the slide operation only, which is independent of the vertical coordinates of the slide operation. Specifically, the horizontal coordinates of each card are compared to the range of [X2, X3] . If a horizontal coordinate of a card falls within the range of [X2, X3] , it indicates that the card is selected by the slide operation, thus being included in the set of cards. Otherwise, if none horizontal coordinate of a card falls within the range of [X2, X3] , it indicates that the card is not selected by the slide operation, thus being excluded from the set of cards.

Returning to FIG. 1, at S103, the apparatus change a selection status of at least one object from the set of objects. In some embodiments, at any given time each object is in one of multiple selection states. For example, each object can be either in a “selected” state or an “unselected” state. The selection status of each object can be changed from one to the other.

In some embodiments, the apparatus changes a selection status of the first object (corresponding to the starting point of the slide option) from the set of objects from a first selection status (e.g. , “unselected” ) to a second selection status (e.g. , “selected” ) . The apparatus then updates a selection status of each remaining object from the set of objects such that the updated selection status of each remaining object is the second selection status. In other words, the apparatus changes the selection status of the first object (i.e. , the object corresponding to the starting point of the slide option) , and updates the selection status of each remaining object from the set of objects to make them identical to the updated selection status of the first object.

In some embodiments, the apparatus can change the selection statuses of the set of objects according to any other suitable rules. For example, when the selection status of each object from the set of objects is “unselected, ” the apparatus changes all of them to be “selected. ” Similarly, when the selection status of each object from the set of objects is “selected, ” the apparatus changes all of them to be “unselected. ”

For another example, when a portion of the set of objects are “unselected” and the remaining objects from the set of objects are “selected, ” the apparatus changes the selection status of each “unselected” object to be “selected, ” and changes the selection status of each “selected” object to be “unselected. ”

For yet another example, regardless of the initial selection status of the set of objects, the apparatus updates the selection status of each object from the set of objects such that the updated selection status of each object from the set of objects is a predefined selection status (e.g. , “unselected” or “selected” ) . In this scenario, it is possible that the apparatus does not change the selection status of any object from the set of objects.

FIG. 2 is a flowchart illustrating a method 200 performed at an apparatus for selecting objects displayed in a user interface of the apparatus in accordance with some embodiments. The apparatus performing the method 200 can be structurally and functionally similar to the apparatus performing the method 100 as described above with respect to FIG. 1. Particularly, the apparatus performing the method 200 can include one or more processors and memory.

In some embodiments, the method 200 is implemented using instructions or code of an application program that are stored in a non-transitory computer readable storage medium of the apparatus and executed by the one or more processors of the apparatus. In such embodiments, the application program is associated with displaying and manipulating visual representations of objects on the user interface of the apparatus. Instructions of the application program are stored in and/or executed at the apparatus. As a result of such an application program being executed, the method 200 is performed to manipulate the objects displayed in the user interface. As shown in FIG. 2, the method 200 includes the following steps.

At S201, the apparatus receives information of a touch operation performed on the user interface of the apparatus. The information of the touch operation includes location information of the touch operation. Similar to the operations of S102 of the method 100 shown and described with respect to FIG. 1, the information of the touch operation can include, for example, coordinates of the touch point (s) of the touch operation.

At S202, the apparatus identifies an object from a group of objects displayed in the user interface based on the location information of the touch operation and location information of the group of objects. Similar to the operations of S102 of the method 100 shown and described with respect to FIG. 1, the apparatus can identify the object from the group of objects based on the location information of the group of objects and coordinates of the touch point (s) of the touch operation. In some embodiments, the identification can be based on both vertical and horizontal coordinates of the touch point (s) . In some other embodiments, the identification can be based on only one of the vertical coordinate and the horizontal coordinate of the touch point (s) , which is dependent of the other coordinate of the touch point (s) .

As an example, FIG. 2a is a schematic diagram illustrating a user interface 210 of the apparatus associated with performing the method in FIG. 2. As shown in FIG. 2a, a group of cards (i.e. , objects) are displayed roughly in a row at the bottom of the user interface 210. Each card corresponds to a range of horizontal coordinates. Specifically, the left-most horizontal coordinate for the first card (from left to right) is X, and the horizontal distance occupied by each card is L. Thus, the range of horizontal coordinates corresponding to the first card is [X, X+L) , the range of horizontal coordinates corresponding to the second card is [X+L, X+2L) , the range of horizontal coordinates corresponding to the third card is [X+2L, X+3L) , etc.

Accordingly, in response to determining the horizontal coordinate of the touch operation as X1 (regardless of the vertical coordinate of the touch operation) , the apparatus can identify which card corresponds to the touch operation by determining which range of horizontal coordinates includes X1. For example, if X+ (A-1) *L ≤ X1 < X+A*L, then the touch operation corresponds to the A-th card from the left.

In some embodiments, to expedite the calculation, the range of horizontal coordinates corresponding to the horizontal axis of the user interface 210 can be divided into a group of small ranges, each of which corresponds to a card from the group of cards displayed in the user interface 210 or a void space (i.e. , associated with no card) . Thus, the apparatus can identify the card corresponding to the touch operation by determining which small range the horizontal coordinate of the touch operation falls into.

At S203, the apparatus determines a selection status of the identified object and changes the selection status of the identified object. Similar to the operations of S103 of the method 100 shown and described above with respect to FIG. 1, by changing the selection status of the identified object, the apparatus can select an “unselected” object or unselect a “selected” object.

FIG. 3 is a flowchart illustrating a method 300 performed at an apparatus for selecting objects displayed in a user interface of the apparatus in accordance with some embodiments. The apparatus performing the method 300 can be structurally and functionally similar to the apparatus performing the method 100 as described above with respect to FIG. 1. Particularly, the apparatus performing the method 300 can include one or more processors and memory.

In some embodiments, the method 300 is implemented using instructions or code of an application program that are stored in a non-transitory computer readable storage medium of the apparatus and executed by the one or more processors of the apparatus. In such embodiments, the application program is associated with displaying and manipulating visual representations of objects on the user interface of the apparatus. Instructions of the application program are stored in and/or executed at the apparatus. As a result of such an application program being executed, the method 300 is performed to manipulate the objects displayed in the user interface. As shown in FIG. 3, the method 300 includes the following steps.

At S301, the apparatus receives information of an operation performed on the user interface of the apparatus. The information of the operation includes location information of the operation. The operations are similar to operations of S101 of the method 100 and S201 of the method 200 shown and described above with respect to FIGS. 1 and 2. In some embodiments, the location information of the operation includes coordinates of the touch point (s) of the operation. The operation can be, for example, a slide operation, a touch operation, or any other type of operation performed on the user interface by a user of the apparatus.

At S302, the apparatus determines, based on the location information of the operation, whether the operation is performed within a first predefined area of the user interface or a second predefined area of the user interface. In some embodiments, the second predefined area is defined to be an area of the user interface where the objects are displayed； and the first predefined area is defined to include all other operable area excluding the second predefined area.

In some embodiments, various types of operations are accepted within each different area of the user interface. In such embodiments, when an operation not accepted in an area is performed within that area, that operation is not accepted by the apparatus. That is, the apparatus does not recognize the operation or respond to the operation. For example, touch operations but not slide operations are accepted within the first predefined area (i.e. , the operable area where the objects are not displayed) , while slide operations but not touch operations area accepted within the second predefined area (i.e. , the area where the objects are displayed) .

In some embodiments, when an operation is detected to be within the first predefined area, the operation is treated as a touch operation but not a slide operation； and when an operation is detected to be within the second predefined area, the operation is treated as a slide operation but not a touch operation. As a result, a slide operation performed in the first predefined area is treated as a touch operation, where the starting point of the slide operation is treated as the only touch point of the touch operation. Similarly, a touch operation performed in the second predefined area is treated as a slide operation having a short path.

If the apparatus determines that the operation is performed within the first predefined area of the user interface, at S303, the apparatus receives information of a touch operation, and identifies an object from a group of objects displayed in the user interface based on location information of the touch operation. The operations are similar to operations of S201-S202 of the method 200 shown and described above with respect to FIG. 2.

Otherwise, if the apparatus determines that the operation is performed within the second predefined area of the user interface, at S304, the apparatus receives information of a slide operation, and identifies a set of objects from the group of objects based on location information of the slide operation. The operations are similar to operations of S101-S102 of the method 100 shown and described above with respect to FIG. 1.

At S305, the apparatus updates a selection status of each identified object accordingly. Specifically, if the apparatus determines that the operation is performed within the first predefined area of the user interface (at S302) and receives information of a touch operation accordingly (at S303) , the apparatus can perform operations similar to operations of S203 of the method 200 shown and described above with respect to FIG. 2. Otherwise, if the apparatus determines that the operation is performed within the second predefined area of the user interface (at S302) and receives information of a slide operation accordingly (at S304) , the apparatus can perform operations similar to operations of S103 of the method 100 shown and described above with respect to FIG. 1.

As an example, FIGS. 3a-3b are schematic diagrams illustrating a user interface 310 of the apparatus associated with performing the method 300 in FIG. 3. As shown in FIGS. 3a-3b, a group of cards are displayed within an area 330 at the bottom of the user interface 310. Thus, the area 330 is the second predefined area. The first predefined area is other operable area in the user interface 310 excluding the other items displayed in the user interface 310.

As shown in FIG. 3a, an operation is performed within the first predefined area. Thus, the operation is received as a touch operation, and a card from the group of cards is identified based on the location of the touch operation. For example, as described above with respect to S202 of the method 200 in FIG. 2, the apparatus can identify the card from the group of cards based on the horizontal coordinate of the touch operation falling within a range of horizontal coordinates corresponding to the location of that card. The apparatus then changes the selection status of the identified card.

As shown in FIG. 3b, an operation is performed within the second predefined area (i.e. , the area 330) . Thus, the operation is received as a slide operation, and a set of cards are determined from the group of cards based on location information of the slide operation. For example, as described above with respect to S102 of the method 100 in FIG. 1, the apparatus can determine the set of cards from the group of cards based on the horizontal coordinates of the slide operation falling within a range of horizontal coordinates corresponding to the collective location of the set of cards. The apparatus then updates the selection status of the set of cards in accordance with a predefined rule, as described with respect to S103 of the method 100 in FIG. 1.

In some embodiments, although not shown in FIGS. 3a and 3b, a slide operation can start from a starting point within the second predefined area (i.e. , the area where the group of objects are displayed) and end at an end point within the first predefined area (i.e. , the operable area where the group of objects are not displayed) . For example, the apparatus can determine, based on location information of the slide operation and location information of the group of objects, whether the starting point corresponds to location of an object from the group of objects and whether the end point corresponds to location of an object from the group of objects. Specifically, in some embodiments, the apparatus can determine whether at least one coordinate of the starting point corresponds to the location of any object from the group of objects, and whether at least one coordinate of the end point corresponds to the location of any object from the group of objects. The apparatus can determine that the starting point corresponds to location of an object from the group of objects (indicating the starting point is within the second predefined area) , while the end point does not correspond to any object from the group of objects (indicating the end point is within the first predefined area) .

In such embodiments, as a result of the slide operation crossing the border between the first predefined area and the second predefined area, the apparatus can, for example, optionally identify a set of objects from the group of objects displayed in the user interface and perform a predefined operation on each object from the set of objects or each object from the group of objects. For example, the apparatus can update the selection status of the group of objects such that the updated selection status of each object from the group of objects is a predefined selection status (e.g. , “unselected” ) . That is, in a card game, by detecting a slide operation crossing the border between the first predefined area and the second predefined area, the apparatus can cancel each “selected” card and make all the cards “unselected. ”

FIG. 4 is a flowchart illustrating a method 400 performed at an apparatus for selecting objects displayed in a user interface of the apparatus in accordance with some embodiments. The apparatus performing the method 400 can be structurally and functionally similar to the apparatus performing the method 100 as described above with respect to FIG. 1. Particularly, the apparatus performing the method 400 can include one or more processors and memory.

In some embodiments, the method 400 is implemented using instructions or code of an application program that are stored in a non-transitory computer readable storage medium of the apparatus and executed by the one or more processors of the apparatus. In such embodiments, the application program is associated with displaying and manipulating visual representations of objects on the user interface of the apparatus. Instructions of the application program are stored in and/or executed at the apparatus. As a result of such an application program being executed, the method 400 is performed to manipulate the objects displayed in the user interface. As shown in FIG. 4, the method 400 includes the following steps.

At S401, the apparatus receives information of a first touch operation performed on the user interface of the apparatus. The information of the first touch operation includes location information of the first touch operation. The first touch operation can include a single touch point (e.g. , contact by a single finger of a user with a screen of the apparatus) . The operations are similar to operations of S101 of the method 100 and S201 of the method 200 shown and described above with respect to FIGS. 1 and 2. In some embodiments, the location information of the first touch operation includes coordinates of the single touch point of the first touch operation. In some embodiments, the information of the first touch operation includes information indicating the number of touch points of the first touch operation.

At S402, the apparatus identifies an object from a group of objects displayed in the user interface based on the location information of the first touch operation and location information of the group of objects. At S403, the apparatus determines a selection status of the identified object and change the selection status of the identified object. The operations of S402-S403 are similar to operations of S202-S203 of the method 200 shown and described above with respect to FIG. 2.

Particularly, in some embodiments, the apparatus can identify the object from the group objects based on only one of the vertical coordinates and the horizontal coordinates of the group of objects and the location information of the first touch operation. For example, the apparatus can identify the object such that a horizontal coordinate of the location of the touch operation corresponds to a horizontal coordinate of the identified object, while a vertical coordinate of the location of the touch operation does not correspond to any vertical coordinate of the identified object.

At S404, the apparatus receives information of a second touch operation performed on the user interface. The information of the second touch operation indicates a number of touch points of the second touch operation. At S405, the apparatus determines whether the number of touch points of the second touch operation is greater than a threshold number of touch points. In some embodiments, such a threshold number can be, for example, one. Thus, the apparatus determines whether the number of touch points of the second touch operation is one or more than one.

In some embodiments, a touch operation can be determined to have multiple touch points in various methods. For example, a touch operation can be determined to have multiple touch points (e.g. , two touch points) if multiple spatially-separate contacts are made with the screen (e.g. , touch screen) of the apparatus at (substantially) the same time. For instance, two fingers of a user contact the screen at the same time. For another example, a touch operation can be determined to have multiple touch points (e.g. , two touch points) if multiple temporally-separate contacts (spatially-separate or not) are made with the screen (e.g. , touch screen) of the apparatus within a very short of time period. For instance, a finger of a user contacts the screen twice within 0.5 seconds.

In some embodiments, if the number of touch points of the second touch operation is equal to or less than the threshold number, the apparatus performs the operations of S402-S403 described above accordingly. For example, the apparatus can identify an object from the group of objects based on the location of the second touch operation and location information of the group of objects (e.g. , the location of the second touch operation being associated with the location of the identified object) . The apparatus can then change the selection status of the identified object.

At S406, if the number of touch points of the second touch operation is greater than the threshold number, the apparatus identifies a set of objects from the group of objects displayed in the user interface and perform a predefined operation on each object from the set of objects. In some embodiments, the apparatus can identify the set of objects based on, for example, the selection status of the set of objects. For example, the apparatus can include each “unselected” object from the group of objects into the set of objects, and then change their selection status to “selected. ” For another example, the apparatus can include each “selected” object from the group of objects into the set of objects, and then change their selection status to “unselected. ”

In some embodiments, the predefined operation includes changing the location of the set of objects on the user interface. For example, in a card game application, the apparatus can include each “selected” card from a group of cards into a set of cards, and then change the location of each card from the set of cards on the user interface to a location farther away from the unselected cards, which indicates that each selected card is played out from the group of cards.
