Description

Method and device for controlling terminal equipment

Technical Field

The present invention relates to the field of multi-touch technologies, and in particular, to a method and an apparatus for controlling a terminal device.

Background

With the skilled use of touch screen terminals and touch pads, gestures other than clicking are designed continuously, and in recent years, the multi-touch technology is mature and the multi-touch method is abundant. Multi-touch (Multi-touch) enables simultaneous input of multiple fingers.

Users often rely on hard keys, or rather difficult to remember, for example, when using more frequent operations or functions, such as multitasking. In general, the multitasking list in the background can be switched by double-clicking a hard key (for example, Home key) of a designated terminal device. However, since switching multitasking is an operation that is frequently used by a user, it is likely that the operation is inconvenient as the use time increases due to the aging of hardware due to the excessive number of operations. And the switching of the multitask list can be realized by clicking a virtual key. However, since switching multitasking is an operation that is frequently used by a user, a virtual key needs to be provided at any time or on any interface, and therefore limited interface space is occupied.

Therefore, how to conveniently and quickly call the functions of the terminal equipment without using hard keys is an urgent problem to be solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the invention can be applied to various terminal devices which take a touch screen (or a touch display) as input/output equipment and complete various functions based on the touch operation of a user on the touch screen, such as smart phones, tablet computers, computing equipment with the touch screen, information display equipment or communication equipment and the like.

110, a touch to a touch screen of the terminal device is detected.

For example, a touch of a finger to the touch screen may be detected in a state of the non-lock screen, and a touch signal may be generated. The touch screen may be a dedicated touch screen or may be a touch-enabled display device. In multi-touch technology, a touch screen may receive a touch or input of one or more touch points (e.g., a finger or a pen) through a touch event processing function and generate a corresponding touch signal for indicating a touch action. For example, the touch screen generates a series of touch signals according to a series of motions (or referred to as a touch gesture). The touch signal may be different according to the operating principle of the touch technology, and the present invention is not limited thereto. Basic touch gestures of a finger may include actions of pressing (down), moving (move), and lifting (up) of the finger. The gesture may be represented by a gesture event, and coordinates and time of the gesture event may be derived from a touch signal generated by the gesture. The touch gesture according to the embodiment of the present invention may be formed by combining motions of pressing, moving, and lifting of a finger, and the gesture according to the embodiment of the present invention may be recognized by detecting the motions of pressing, moving, and lifting, respectively, and the embodiment of the present invention is not limited thereto, and for example, the gesture according to the embodiment of the present invention may also be represented by a touch event by whether the touch event is triggered to recognize the gesture.

It should be understood that the above-mentioned touch may be a complete contact manner, or may be a floating touch manner, for example, when a floating touch is implemented, a certain gap may exist between the finger and the touch screen.

And 120, calling a preset function of the terminal device when the plurality of touch points are detected and the positions of the plurality of touch points are within a preset range or the relative distances of the plurality of touch points meet a preset value.

Preferably, the plurality of touch points are at least three touch points, and the embodiment according to the present invention is not limited thereto, for example, the plurality of touch points may be two touch points. For example, when a series of touch signals transmitted by the touch screen are received, it may be determined whether more than three touch points are detected, and it may be determined whether the touch points are located within a preset range or whether the relative distances of the touch points satisfy a preset value, that is, it is recognized whether the finger of the user makes the touch gesture. The position of the touch points in the preset range may refer to whether the touch points are in the preset range when touching the touch screen, or whether the touch points stop in the preset range after moving. Whether the relative distance between the touch points meets a preset value or not can mean whether the distance between the touch points and the touch screen meets the preset value or not when the touch points touch the touch screen. In other words, the multi-application user interface is displayed on the touch screen whenever the positions of the touch points are within a preset range or the relative distances of the touch points satisfy a preset value, regardless of whether the touch points are moved or not. The position of the touch points in the preset range may refer to that the coverage of the touch points (e.g., the area of the area surrounded by the circle where the touch points are located, etc.) is larger than the preset range or smaller than the preset range, or may refer to that the touch points are located in a designated area on the touch screen. The relative distance of the touch points satisfying the preset value refers to whether the distance between the touch points (e.g., the distance between a certain two points or the average of the distances between two points) is greater than or less than a certain preset value.

The actions of touching, moving and stopping the finger of the user on the touch screen form a visual gesture, the finger of the user completes one touch gesture by making the action, and the determination of whether a plurality of touch points are detected and whether the plurality of touch points are located in a preset range means that the identification of whether the finger of the user completes the touch gesture on the touch screen. In other words, the preset function of the terminal device may be invoked when the touch gesture is recognized.

According to the embodiment of the invention, the touch gesture designed by the embodiment of the invention can be recognized through the number and the position or the relative distance of multi-point touch, and the preset function of the terminal equipment can be quickly called through recognizing the visual touch gesture designed by the embodiment of the invention, so that the user can smoothly complete the operation, and the user experience is optimized.

In addition, when the user uses the more frequent operation, the user does not need to rely on the hard keys, the use times of the hard keys can be reduced, the hardware aging is prevented, and virtual keys do not need to be arranged on each user interface, so that the space of the user interface is saved.

For example, the preset function may include a function of causing a display of the terminal device to display or call a certain user interface, but the embodiment of the present invention is not limited thereto, and may also include a function of shutting down, returning to a main interface, entering a certain special application program, or returning to a previous application program.

According to the embodiment of the invention, when it is determined that the plurality of touch points are detected and the positions of the plurality of touch points are within a preset range or the relative distances of the plurality of touch points meet a preset value, the display screen of the terminal device can be made to display the multi-application user interface.

Optionally, as another embodiment, when it is determined that the plurality of touch points are detected and the positions of the plurality of touch points are within a preset range or the relative distances of the plurality of touch points satisfy a preset value, a shutdown program of the terminal device may be invoked to implement soft shutdown, so as to avoid that the user frequently uses a hard key to perform shutdown operations.

Optionally, as another embodiment, the main interface may be returned or invoked when it is determined that the plurality of touch points are detected and the positions of the plurality of touch points are within a preset range or the relative distances of the plurality of touch points satisfy a preset value.

Optionally, as another embodiment, when it is determined that the plurality of touch points are detected and the positions of the plurality of touch points are within a preset range or the relative distances of the plurality of touch points satisfy a preset value, an application icon or all application icons currently in use may be displayed on the display screen. In this way, the user can conveniently select the application program to be run according to the requirement.

Optionally, as another embodiment, when it is determined that the plurality of touch points are detected and the positions of the plurality of touch points are within a preset range or the relative distances of the plurality of touch points satisfy a preset value, a certain specific application program on the terminal device may be run, for example, in any user interface, and if the terminal device recognizes the touch gesture, a certain application program (for example, instant messaging software) may be invoked.

Optionally, as another embodiment, the terminal device may further enter a retrieval interface when it is determined that the plurality of touch points are detected and the positions of the plurality of touch points are within a preset range or the relative distances of the plurality of touch points satisfy a preset value.

Optionally, as another embodiment, it is also possible to return to the last application executed by the terminal device when the above condition is satisfied.

Embodiments of the present invention are described in detail below with an example of displaying a multi-application user interface.

Fig. 1B is a schematic flow chart of a method of controlling a terminal device according to one embodiment of the present invention.

And 150, detecting the touch on the touch screen of the terminal equipment.

And 160, when the plurality of touch points are detected and the positions of the plurality of touch points are within a preset range or the relative distances of the plurality of touch points meet a preset value, enabling the display screen of the terminal device to display the multi-application user interface.

For example, the multi-application user interface may include a list of applications running in the background of the terminal device, that is, a multi-task list or a multi-task icon set for performing multi-task switching, may also include a list of applications frequently used by the user or a set of application icons, and may also include a list of applications recently used by the user or a set of application icons. The multi-application user interface may be configured by the manufacturer or by the user.

The displaying of the multi-application user interface on the touch screen may refer to calling the multi-application user interface from the memory and displaying the multi-application user interface on the display screen, or may refer to removing or removing another user interface that blocks the multi-application user interface to display the multi-application user interface.

The touch screen and the display screen may be separate physical entities or may be the same physical entity, which is not limited according to the embodiment of the present invention. In other words, the touch screen and the display screen may be designed integrally or may be respectively set up on different devices.

In 160, it may be determined whether the movement of at least one of the plurality of touch points exceeds a preset distance when it is determined that the plurality of touch points are detected, and it may be determined whether the at least one of the plurality of touch points stops within the preset range or whether the relative distance of the plurality of touch points after stopping satisfies the preset value when it is determined that the movement of the at least one of the plurality of touch points exceeds the preset distance; and when the touch points are determined to stop in the preset range or the relative distances of the touch points after stopping meet the preset value, enabling the display screen of the terminal equipment to display the multi-application user interface.

For example, it may be detected whether at least one of the touch points moves a distance after touching the touch screen and is within a preset range after moving a distance or a relative distance between the touch points after movement is stopped satisfies the preset value. The preset range may refer to a preset relative range (e.g., an area of a region surrounded by a circle where the touch points are located, etc.), or may refer to an absolute range (e.g., a preset specific region on the touch screen). For example, the display screen may be caused to display the multi-application user interface when the relative distance between the touch points exceeds a preset value or is located in a certain area on the touch screen.

Embodiments according to the present invention may determine a position of each touch point according to the touch signal, track a change in the position of each touch point, and determine whether the touch point stops within a preset range after moving or whether a relative distance between the touch points after the movement stops satisfies the preset value according to the change in the position of each point, i.e., whether the above-described touch gesture is completed. According to the embodiment of the invention, the touch gesture designed by the embodiment of the invention can be recognized by combining the motion (movement), the point number and the relative position of the touch point, so that the gesture action is more vivid and abundant.

Further, it may be determined whether or not each of the operations of the touch gesture, such as the touch, the movement, and the stop, is completed in sequence, and the determination after the operation may be stopped as long as any one of the operations is not completed. For example, if the touch screen is not touched by a plurality of touch points, subsequent determination is not performed, and if the moving distances of the plurality of touch points do not exceed the preset distance, subsequent determination is not performed, so that misoperation and consumption of system resources are avoided.

Optionally, as another embodiment, it may be further determined whether a dwell time of the initial touch position on the touch screen when the plurality of touch points touch the touch screen exceeds a first preset time after the plurality of touch points are determined, wherein in 160, it may be determined whether a movement of at least one of the plurality of touch points exceeds the preset distance when the touch of the plurality of touch points is detected and the dwell time of the initial touch position on the touch screen of the plurality of touch points exceeds the first preset time.

For example, the first preset time may be set according to an ergonomic principle, that is, according to a time that a person may stay when initially touching the touch screen when making the gesture in a normal state, for example, the first preset time may be set to 0.5 second, a timer may be used to time the stay time of the touch points at the stop positions within a preset range, and when the timer reaches 0.5 second, it is determined whether the movement of at least one of the touch points exceeds the preset distance. Due to the fact that the first preset time is set, the touch gesture is richer in performance and is easily distinguished from other gestures, and misoperation is avoided. The initial touch position may refer to a position where a plurality of touch points initially contact the touch screen and are not moved.

Optionally, as another embodiment, after the movement of at least one of the touch points is stopped, it may be determined whether the dwell time of the stop positions of the touch points in the preset range or the dwell time of the touch points whose relative distances after the stop satisfy the preset value exceeds a second preset time, where in 160, the display screen of the terminal device may be caused to display a multi-application user interface when the dwell time of the stop positions of the touch points in the preset range or the dwell time of the touch points whose relative distances after the stop satisfy the preset value is determined to exceed the second preset time.

For example, the second preset time may be set according to an ergonomic principle, that is, according to a time that a person stays on the touch screen when the person normally performs the gesture, and stops moving, for example, the second preset time may be set to 0.5 second, the timer is used to time the stay time of the touch points at the stop positions within the preset range, and when the timer reaches 0.5 second, the multi-application user interface is displayed. Optionally, after the plurality of touch points stop moving, if the relative distance between the plurality of touch points is greater than a certain preset value, and the staying time at the stop position when the relative distance between the plurality of touch points is greater than the preset value reaches 0.5 seconds, displaying the multi-application user interface. Due to the fact that the second preset time is set, the touch gesture is richer in performance and is easily distinguished from other gestures, and misoperation is avoided.

At 160, the positioning of the plurality of touch points within a preset range includes: or the area of a triangle formed by the plurality of touch points is smaller than a third preset value; or the area of the circle where the touch points are located is smaller than a fourth preset value; or the area of a polygon formed by the plurality of touch points is larger than a seventh preset value; or the area of the circle where the touch points are located is larger than an eighth preset value; or the circumference of a polygon formed by the plurality of touch points is smaller than a ninth preset value; alternatively, the plurality of touch points stop at the designated area on the touch screen.

In 160, the step of enabling the relative distances of the touch points to satisfy the preset value includes: the average value of the relative distances between every two touch points is smaller than a first preset value; or the maximum value of the relative distances between every two touch points is smaller than a second preset value; or the average value of the relative distances between every two touch points is greater than a fifth preset value; or the maximum value of the relative distances between every two touch points is larger than a sixth preset value.

For example, the parameters defining the preset range may be set according to ergonomic statistical parameters. Specifically, the parameters of the touch gestures input by a plurality of users may be counted, for example, the relative positional relationship between the touch points after the touch points stop every time the touch gestures are performed by the plurality of users may be counted, and the preset range and the preset distance may be determined according to the relative positional relationship. Taking the preset area as the circle as an example, if most of the user makes the above gesture, the gesture stops at the area of 40mm²The circle of (2) can be set with a certain threshold value smaller than 40 as the preset range, so that more natural touch gestures can be recognized, and the recognition of the touch gestures is more accurate, thereby greatly improving the user experience. Meanwhile, the preset range enables the touch gesture to be easily distinguished from other gestures.

In 160, it may be determined whether the movement of each of the at least one touch point exceeds the preset distance in a case where the plurality of touch points are distant (spread) from each other.

In other words, the touch gesture may be an action in which a plurality of touch points are spread on the touch screen.

Alternatively, as another embodiment, in 160, it may be determined whether the movement of each of the at least one touch point exceeds the preset distance in a case where the plurality of touch points approach (contract) to each other.

In other words, the touch gesture is an action in which a plurality of touch points are contracted on the touch screen.

The expansion and contraction actions of the touch gesture allow the touch gesture to be recognized in conjunction with the movement direction of the touch point.

Optionally, as another embodiment, the method of fig. 1B further includes: and after detecting that the plurality of touch points or the movement of at least one touch point in the plurality of touch points exceeds the preset distance, enabling the display screen to display the preset range.

For example, after a plurality of touch points touch the touch screen or after the plurality of touch points move the preset distance, the preset area may be calculated according to the relative position relationship of the plurality of touch points, and the preset area may be displayed on the touch screen, for example, the preset area may be displayed in a semi-transparent circular or triangular pattern, so as to prompt the user to accurately move to the preset area.

Optionally, as another embodiment, the preset range and/or the preset value and/or the preset distance may be set according to a preference of the user or a usage habit of the user.

For example, the touch gestures made by the user may be trained or learned before the user formally makes the touch gestures, or during the use of the terminal device. Specifically, a plurality of touch gestures input by a user can be received, and parameters of the touch gestures of the user are counted. For example, every time the user makes the touch gesture, the relative positional relationship after the touch points stop is counted, and the preset range and the preset distance are determined according to the relative positional relationship. Taking the preset range as the area of a circle as an example, if the touch gestures performed by the user for a plurality of times are mostly (for example, more than 90%) stopped at the area of 40mm²A threshold value smaller than 40 may be set as the above-mentioned preset range. The preset range and the preset distance are set according to the preference of the user or the use habit of the user, so that the set parameters of the touch gesture can better accord with the preference and the use habit of the user, the more natural touch gesture can be recognized, the recognition of the touch gesture is more accurate, and the user experience is greatly improved.

In 160, when it is determined that the plurality of touch points are detected, it may be determined whether positions of the plurality of touch points are within a preset range or whether relative distances of the plurality of touch points satisfy the preset value; and when the plurality of touch points are determined to be located in the preset range or the relative distances of the plurality of touch points meet the preset value, enabling the display screen of the terminal equipment to display the multi-application user interface.

Fig. 2 is a schematic flow chart of a method of controlling a terminal device according to another embodiment of the present invention. The method comprises the following steps. Descriptions similar to those of fig. 1B are not repeated herein.

210, a touch to a touch screen of the terminal device is detected.

And 220, when the plurality of touch points are determined to be detected and the movement of at least one touch point in the plurality of touch points exceeds a preset distance, enabling the display screen to display the multi-application user interface.

For example, the multi-application user interface may be a list of applications running in the background of the terminal device, that is, a multi-task list or a multi-task icon set, an application list or an application icon set frequently used by the user, or an application list or an application icon set recently used by the user. The multi-application user interface may be configured by the manufacturer or by the user.

Preferably, the plurality of touch points are at least three touch points, and the embodiment according to the present invention is not limited thereto, for example, the plurality of touch points may be two touch points.

According to the embodiment of the invention, the touch gesture designed by the embodiment of the invention can be recognized through the number of points of multi-point touch and the moving distance, and the multi-application user interface can be quickly displayed through recognizing the visual touch gesture designed by the embodiment of the invention, so that the user can smoothly complete the operation, and the user experience is optimized.

Optionally, as another embodiment, the method of fig. 2 further includes: and determining whether the plurality of touch points stop within a preset range or whether the relative distances of the plurality of touch points after stopping meet the preset value, wherein at 220, the display screen can be enabled to display the multi-application user interface when determining that the plurality of touch points stop within the preset range or the relative distances of the plurality of touch points after stopping meet the preset value.

Embodiments of the present invention are described in more detail below with reference to specific examples.

Fig. 3 is a schematic flow chart of a process of controlling a terminal device according to one embodiment of the present invention. The method of fig. 3A is an example of the method of fig. 1A and 1B. Fig. 3B to 3C are schematic diagrams illustrating a touch gesture performed on a touch screen according to an embodiment of the present invention. FIG. 3D is a schematic diagram of a user interface after displaying a multi-application user interface, according to an embodiment of the invention.

And 310, detecting the touch of the touch points on the touch screen.

The touch screen or the touch screen with the touch function can monitor or detect actions of initial touch, movement, stop movement and the like of a touch point on the touch screen, and generate a touch signal according to the actions. In other words, the touch screen may generate a series of touch signals according to a series of actions (operations or physical movements) performed by a User on a gesture-based User Interface (UI), i.e., a touch gesture. Touch screens may employ capacitive touch technology to generate touch signals, and embodiments in accordance with the invention are not limited in this respect, and may also employ optical (e.g., with infrared or laser) or resistive touch technology to generate touch signals, for example.

320, determine if multiple touch points are detected? If so, execution continues with step 330, otherwise, execution 360.

A determination may be made as to whether multiple (e.g., at least three) touch points touch the touch screen based on touch signals generated by the touch screen in relation to the initial touch. Taking capacitive touch technology as an example, in a touch screen based on mutual capacitance, mutual capacitance is generated between a row line and a column line, and if a finger exists on the touch screen, the mutual capacitance is reduced, so that the touch existence on the touch screen can be judged, and the position of each touch point can be accurately judged. In this case, the touch signal may be a signal indicating a change in capacitance of a touch position where each touch point is located.

330, determine if at least one of the at least a plurality of touch points has moved a predetermined distance? If so, execution continues with step 340, otherwise, execution 360 is performed.

For example, whether the plurality of touch points move by a preset distance may be detected according to a touch signal generated by the touch screen and related to the movement of the touch points. For example, the movement of each touch point can be tracked by the touch identifier corresponding to each touch point, and the step 340 is executed only when the distance moved by each touch point exceeds a certain preset distance or threshold (e.g., 1 mm), and otherwise no response is made. In other words, a touch point is considered to have moved only if the distance that each touch point has moved exceeds some preset distance or threshold. In particular, the preset distance or threshold may be set to 0.

340, determine whether each touch point stops within a preset range or whether a relative distance between each touch point satisfies a preset value? If so, execution continues with step 350, otherwise execution 360 is performed.

For example, when the respective touch points stop moving, whether the respective touch points stop within a preset range may be determined according to the touch signal, or whether a relative distance between the respective touch points satisfies a preset value may be determined according to the touch signal. For example, the relative position of the current touch point is determined according to the touch signal, and whether each touch point is within a preset range is determined according to the relative position.

Since the touch gesture may be an expanding or diverging gesture or a contracting gesture. Therefore, the movement of the respective touch points may be in opposite directions or in opposite directions.

For example, when the touch points move toward each other, the touch points stop within the preset range may be determined according to the following principle: the area of a triangle formed by all the touch points is smaller than a third preset value; or the area of the circle where each touch point is located is smaller than the fourth preset value. Whether the relative distance between the touch points meets a preset value is determined according to the following principle: the average value of the relative distances between every two touch points is smaller than a first preset value; or the maximum value of the relative distance between every two touch points is smaller than a second preset value.

For example, when each touch point moves in a reverse direction, each touch point stops within a preset range may be determined according to the following principle: the area of a polygon formed by all the touch points is larger than a seventh preset value; or the area of the circle where each touch point is located is larger than the eighth preset value. Whether the relative distance between the touch points meets a preset value is determined according to the following principle: the average value of the relative distances between every two touch points is greater than a fifth preset value; or the maximum value of the relative distance between every two touch points is larger than a sixth preset value.

Of course, the preset range may also be a designated area on the touch screen, for example, a circular or square area in the center of the touch screen. Referring to fig. 3B, 3C, and 3D, for example, when the three touch points located at the positions A, B and C, respectively, are moved to the positions a ', B ', and C ', i.e., to the circular area D at the center of the touch screen, the respective touch points are located within the above-mentioned preset range.

According to the principle of determining the preset range, abundant and various touch gestures can be provided so as to be better distinguished from other operations, and therefore misoperation is avoided.

And 350, in case that the respective touch points stop within a preset range or the relative distance between the respective touch points satisfies a preset value, causing the display screen to display the multi-application user interface (or menu).

For example, the multi-application user interface may be a list of various tasks that are running on the terminal device. When the user wants to switch tasks, the multi-application user interface can be displayed so as to select the tasks to be switched from the multi-application user interface. According to the embodiment of the invention, under the condition that the touch gesture is detected, an instruction for displaying the multi-application user interface can be sent out, so that the multi-application user interface can be conveniently displayed under the condition that a hard key or a virtual key is not required to be pressed.

No response is made to the incomplete gesture 360.

If the user does not complete the series of actions (i.e., touch gestures), for example, does not move a sufficient distance or stop within a preset range, no response is made, i.e., the multi-application user interface is not displayed, so that a malfunction can be avoided.

The method of fig. 4 is an example of the method of fig. 1A and 1B. 310, 330 to 460 of fig. 4 are similar to 310, 330 to 360 of fig. 3A, and are not described again here.

A touch to the touch screen is detected 410.

420, determine if multiple touch points are detected? If so, execution continues with step 425, otherwise, execution proceeds with step 460.

425, determine if the dwell time of each touch point exceeds a first preset time? If so, 430 is performed, otherwise 460 is performed.

Referring to fig. 3B, for example, the three touch points respectively stay or remain motionless at the initial touch positions A, B and C for more than a first preset time (e.g., 0.5 seconds). For example, a timer may be set to time the time that each touch point stays at the initial touch position, and execution 430 is performed when the stay time exceeds a first preset time.

430, determine whether at least one of the plurality of touch points has moved a predetermined distance? If so, execution continues with step 440, otherwise, execution 460 is performed.

440, determine whether each touch point stops within a preset range or whether the relative distance between each touch point satisfies a preset value? If so, execution continues with step 450, otherwise execution proceeds with step 460.

And 450, displaying a multi-application user interface (or menu) in case that the relative distance between the respective touch points stops within the preset range satisfies the preset value.

460 not responding to the incomplete gesture.

The method of fig. 5 is an example of the method of fig. 1A and 1B. 510 to 530 and 560 of fig. 5 are similar to 310 to 330 and 360 of fig. 3 and will not be described again.

A touch to the touch screen is detected 510.

520, determine if multiple touch points are detected? If so, then step 530 continues, otherwise, step 560 is performed.

530, determine whether the movement of at least one of the touch points exceeds a preset distance? If so, execution continues with step 540, otherwise, execution 560.

540, determine whether each touch point stops within a preset range or whether the relative distance between each touch point satisfies a preset value? If so, execution continues at step 545, otherwise execution 560.

545, determine if the dwell time of each touch point exceeds a second preset time? If so, 550 is performed, otherwise 560 is performed.

Referring to fig. 3C, for example, the three touch points respectively stay or remain motionless at the touch positions a ', B ', and C ' after the stop for more than a second preset time (e.g., 0.5 seconds). For example, a timer may be set to count the staying time of each touch point at the touch positions a ', B ', and C ', and the execution 550 is performed when the staying time exceeds a second preset time.

And 550, in case that the staying time of each touch point exceeds a second preset time, causing the display screen to display the multi-application user interface (or menu).

560, no response to the incomplete gesture.
