Those skilled in the art will appreciate that fig. 1 is merely exemplary of a portable electronic device and is not intended to be limiting of portable electronic devices and may include more or fewer components than those shown, or some components may be combined, or different components.

The touch-sensitive display unit 130 is sometimes referred to as a "touch screen" for convenience and may also be referred to as or as a touch-sensitive display system, and may also be referred to as a display having a touch-sensitive surface (touch-sensitive surface). The display with the touch-sensitive surface comprises a touch-sensitive surface and a display screen; a screen interface may be displayed and a touch action may be received.

The touch-sensitive display unit 130 provides an input interface and an output interface between the device and the user. The touch-sensitive display unit 130 may collect touch operations by a user on or near the touch-sensitive display unit, such as user operations on or near the touch-sensitive display unit using a finger 202, joint, stylus, or any suitable object. The touch-sensitive display unit may detect a touch action on the touch-sensitive display unit, a grid capacitance value of the touch-sensitive display unit, and a contact coordinate, send the touch action, the grid capacitance value of the touch-sensitive display unit, and the contact coordinate information to the processor 190, and receive and execute a command sent by the processor 190. The touch-sensitive display unit 130 displays visual output. The visual output may include graphics, text, icons, video, and any combination thereof (collectively "graphics"). In some embodiments, some or all of the visual output may correspond to a user interface object.

The touch-sensitive display unit 130 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch-sensitive display unit 130 may detect contact and any movement or break thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch-sensitive display unit 130.

The electronic device 100 may also include one or more ambient light sensors 153 to keep the touch-sensitive display unit off when the electronic device 100 is in a user's pocket or other dark area to prevent the electronic device 100 from consuming unnecessary battery power or being mishandled while in a locked state. In some embodiments, the proximity light sensor and the ambient light sensor may be integrated into one component or may be provided as two separate components. As for the electronic device 100, other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor may be further configured, and are not further described herein. Although fig. 1 shows the proximity light sensor and the ambient light sensor, it is understood that they do not belong to the essential constitution of the electronic apparatus 100, and may be omitted as needed within a range not changing the essence of the invention.

The storage data area can store the incidence relation between the joint touch gesture and the application function and can also store preset track information. The storage instruction area may store an operating system, instructions required for at least one function, and the like. The instructions may cause processor 190 to perform a method comprising: when an articulation touch gesture is detected that acts on the touch-sensitive surface, it is recognized whether a user interface displayed by the display is a text application interface. And if the user interface displayed by the display is a text application interface and the track of the joint touch gesture is matched with the preset track, responding to the joint touch gesture and displaying a text selection area on the text application interface. The text selection area is positioned between the first endpoint and the second endpoint; the first endpoint is located at a first position in the text application interface, and the second endpoint is located at a second position in the text application interface.

And if the user interface displayed by the display is a text application interface but the track of the joint touch gesture does not match with the preset track, executing a second application function when the second application function associated with the track of the joint touch gesture exists.

The processor 190 is a control center of the electronic device 100, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the electronic device 100 and processes data by operating or executing instructions stored in the memory 120 and calling data stored in the memory 120, thereby performing overall monitoring of the mobile phone. Alternatively, processor 190 may include one or more processing units; preferably, the processor 190 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 190. In some embodiments, the processor, memory, may be implemented on a single chip; in some embodiments, they may also be implemented separately on separate chips. In an embodiment of the present invention, processor 190 is further configured to invoke instructions in the memory to enable, when an articulation touch gesture is detected that acts on the touch-sensitive surface, identifying whether a user interface displayed by the display is a text application interface. And if the user interface displayed by the display is a text application interface and the track of the joint touch gesture is matched with the preset track, responding to the joint touch gesture and displaying a text selection area on the text application interface. The text selection area is positioned between the first endpoint and the second endpoint; the first endpoint is located at a first position in the text application interface, and the second endpoint is located at a second position in the text application interface. Executing the first application function if the user interface displayed by the display is not a text application interface and the first application function associated with the trajectory of the joint touch gesture exists. And if the user interface displayed by the display is a text application interface but the track of the joint touch gesture does not match with the preset track, executing a second application function when the second application function associated with the track of the joint touch gesture exists.

The radio frequency unit 110 may be configured to receive and transmit information or receive and transmit signals during a call, and in particular, receive downlink information of a base station and then process the downlink information to the processor 190; in addition, the data for designing uplink is transmitted to the base station. Typically, the RF circuitry includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like.

The audio circuitry 160, speaker 161, microphone 162 may provide an audio interface between a user and the electronic device 100. The audio circuit 160 may transmit the electrical signal converted from the received audio data to the speaker 161, and convert the electrical signal into a sound signal for output by the speaker 161; on the other hand, the microphone 162 converts the collected sound signal into an electrical signal, which is received by the audio circuit 160 and then converted into audio data, and then the audio data is processed by the audio data output processor 190 and then transmitted to another terminal via the rf unit 110, or the audio data is output to the memory 120 for further processing.

WiFi belongs to short-range wireless transmission technology, and the electronic device 100 can help the user send and receive e-mails, browse web pages, access streaming media, etc. through the WiFi module 170, which provides the user with wireless broadband internet access. Although fig. 1 shows the WiFi module 170, it is understood that it does not belong to the essential constitution of the electronic device 100, and may be omitted entirely as needed within the scope not changing the essence of the invention.

Bluetooth is a short-range wireless communication technology. By using the bluetooth technology, the communication between mobile communication terminal devices such as a palm computer, a notebook computer, and a mobile phone can be effectively simplified, and the communication between the above devices and the Internet (Internet) can also be successfully simplified, so that the data transmission between the electronic device 100 and the Internet becomes faster and more efficient through the bluetooth module 180 of the electronic device 100, and a road is widened for wireless communication. Bluetooth technology is an open solution that enables wireless transmission of voice and data. Fig. 1, however, shows a WiFi module 170, but it is understood that it does not belong to the essential components of the electronic device 100, and may be omitted entirely as needed within the scope not changing the essence of the invention.

The electronic device 100 further includes a power source 193 (e.g., a battery) for supplying power to various components, which may preferably be logically connected to the processor 190 via a power management system 194, such that functions of managing charging, discharging, and power consumption are performed via the power management system 194.

The method for selecting text is described below by taking the electronic device 100 as an example.

Fig. 2 is a schematic external structural diagram of the portable electronic device 100 according to the embodiment of the present invention. In the present embodiment, the electronic apparatus 100 may include a touch-sensitive display unit 130, an acceleration sensor 151, a volume control key 132, a switch key 133, a microphone 162, a speaker 161, an external interface 197, and an earphone jack 163. The touch-sensitive display unit 130 may display one or more graphics 300 in the user interface 200, receive touch inputs from a user, and may reduce the number of physical inputs or controls on the electronic device 100 by using the touch-sensitive display unit 130 as a primary input or control for operating the electronic device 100. In this embodiment, the touch-sensitive display unit may be referred to as a "menu button". In some other embodiments, a "menu button" may be a physical button or other physical input or control device. The acceleration sensor 151 is used for acquiring the gravity acceleration of the touch action of the user on the touch-sensitive display unit in the Z-axis. Turning on or off the power of the electronic device 100 may be accomplished by depressing and holding the switch key in a depressed state for a predetermined time interval. Locking the electronic device 100 may be achieved by depressing the switch button and releasing it before a predetermined time interval. In other embodiments, voice input to activate some functions may also be received through the microphone 162.

Fig. 3 is a schematic diagram illustrating a text selection area according to an embodiment of the present invention. The text selection area 301 may be represented on the touch-sensitive display unit 130 as text bounded by a first endpoint 302a and a second endpoint 302b, located between the first endpoint and the second endpoint. Those skilled in the art will appreciate that the selected text region 301 may contain any portion of the text shown in FIG. 3, and that the text selected in FIG. 3 is merely one example. Further, the first end point 302a may be associated with a first marker post 303a and the second end point 302b may be associated with a second marker post 303 b. First marker post 303a and second marker post 303b may be used to indicate the location of first endpoint 302a and second endpoint 302b, respectively. Since the signpost is easier to manipulate than the end points, when a user wishes to move one or both of the first end point 302a or the second end point 302b to a new location, moving the end point to the new location may be accomplished by moving the signpost associated with the end point to the new location. In some embodiments,

marker posts

303a and 303b may be other shapes, sizes, and colors. This embodiment is merely an example.

Fig. 4 is a flowchart of a method for selecting a text according to an embodiment of the present invention.

Method 400 may be performed on a portable electronic device (e.g., electronic device 100 of fig. 1 or 2) having a touch-sensitive display unit and a plurality of applications, including a text application. In some embodiments, some operations in method 400 may be combined, and/or the order of some operations may be changed.

As described below, the method 400 provides a more efficient way to quickly select text. The method helps the user to select the text by fewer operation steps. The operation steps of selecting the text are simplified, and the user experience is improved.

The portable electronic device detects an articulation touch gesture (401) acting on the touch-sensitive surface.

For example: the step 401 can specifically include steps 4011 to 4013.

The portable electronic device detects a touch action acting on the touch-sensitive surface (4011); judging whether the touch action is a joint touch action (4012); detecting a joint touch gesture consisting of the joint touch actions (4013).

Upon detecting an articulation touch gesture acting on the touch-sensitive surface, identifying whether a user interface displayed by a display is a text application interface (402).

Illustratively, the text application interface may display web browsing, email, notepad, instant messaging, blog application, and the like.

If the user interface displayed by the display is not a text application interface, determining whether an application function associated with the trajectory of the joint touch gesture exists (403). When there is an application function associated with the trajectory of the joint touch gesture, the electronic device executes the application function (404).

And if the user interface displayed by the display is a text application interface, judging whether the track of the joint touch gesture is matched with a preset track (405). And when the track of the joint touch gesture is matched with a preset track, responding to the joint touch gesture, and displaying a text selection area (406) on the text application interface.

Optionally, if the user interface displayed by the display is a text application interface, but the trajectory of the joint touch gesture is not matched with a preset trajectory, determining whether an application function associated with the trajectory of the joint touch gesture exists. When there is an application function associated with the trajectory of the joint touch gesture, executing the application function.

And when the touch-sensitive display unit receives a touch action acting on the touch-sensitive surface, the touch information is transferred to the processor. The touch information may include one or more of touch point coordinates, grid capacitance values of the touch sensitive display unit, and touch actions. The touch actions may include pressing, moving, and lifting actions.

In some embodiments, it may be determined whether the touch action is a joint touch action based on the grid capacitance information and a Z-axis direction acceleration signal generated by the touch action (4012). The touch sensitive surface grid capacitance information includes a grid capacitance value and a grid number of non-zero capacitance values.

When the grid capacitance value meets a first preset capacitance value range, the grid number of the non-zero capacitance value is smaller than a preset value, and the acceleration signal in the Z-axis direction is in the first preset acceleration range, it can be judged that the touch action is a joint touch action. When the grid capacitance value meets a second preset capacitance value range, the grid number of the non-zero capacitance value is larger than or equal to a preset value, and the acceleration signal in the Z-axis direction is in the second preset acceleration range, it can be judged that the touch action is a finger touch action.

For example, when the grid capacitance value of the touch-sensitive display unit indicates that the maximum capacitance value satisfies a first preset capacitance value range (for example, less than or equal to 0.42pF), the number of grids with non-zero capacitance values distributed is less than 7, and the Z-axis direction acceleration signal is within the first preset acceleration range (for example, within 5ms, the acceleration signal is greater than 3g) within a preset time, the touch action may be determined as a joint touch action. When the grid capacitance value of the touch-sensitive display unit indicates that the maximum capacitance value satisfies a second preset capacitance value range (for example, greater than 0.42pF, less than or equal to 0.46pF), the number of grids with non-zero capacitance values distributed is greater than or equal to 7, and in a preset time, the Z-axis direction acceleration signal is within a second preset acceleration range (for example, within 5ms, the acceleration signal is less than 2g, and g is gravity acceleration), it may be determined that the touch action is a finger touch action. It is understood that the joint touch action in the embodiment of the present invention is not necessarily triggered by the finger joint, and other objects may also hit the touch-sensitive display unit 130 at a fast speed, and as long as the determination condition of the joint touch action is satisfied, the joint touch action in the embodiment of the present invention may be referred to as the joint touch action.

The touch gesture may consist of a touch action. For example, a tap gesture consists of two touch actions, press and lift; the swipe gesture consists of three touch actions, a press, a move, and a lift. When it is determined that the touch action is a joint touch action, a joint touch gesture composed of the joint touch actions may be detected (4013). For example: the joint click gesture consists of two joint touch actions of pressing and lifting; the joint sliding gesture consists of three joint touch actions of pressing, moving and lifting.

In some embodiments, by looking up the association relationship between the trajectory of the joint touch gesture and the application function stored in the memory 120, it is determined whether there is an application function associated with the trajectory of the joint touch gesture (403). The joint touch gesture may be composed of different joint touch actions. For example, an articulation tap gesture consists of two articulation touch actions of pressing and lifting, and an articulation slide gesture consists of three articulation touch actions of pressing, moving, and lifting. And the moving track between the pressing and the lifting is the track of the joint touch gesture. The user may preset the association relationship between the trajectories of the various joint touch gestures and the application functions, and store the association relationship between the trajectories of the joint touch gestures and the application functions in the memory 120.

For example, the user may previously set the association relationship of the trajectory "C" of the joint touch gesture with the camera application function, and save the association relationship of the trajectory "C" of the joint touch gesture with the camera application function in the memory 120. When the joint touch gesture with the track of "C" acting on the touch-sensitive surface is detected, the track of the joint touch gesture "C" can be judged to be associated with the camera application function by searching the association relationship between the track of the joint touch gesture stored in the memory 120 and the application function.

In some embodiments, when a depressed articulating touch action is detected in region A of the touch sensitive display unit, the depression moves on the touch sensitive display unit to region B where a raised articulating touch action is detected. The joint touch event that the joint is pressed down in the area A and lifted up after moving to the area B is a joint touch gesture. For example: the position of the touch action (e.g., zone a or zone B) can be determined from the contact coordinate information. The joint touch gesture may be comprised of a joint touch action. For example, an articulation tap gesture consists of two articulation touch actions of pressing and lifting; the joint sliding gesture consists of three joint touch actions of pressing, moving and lifting. The area A is a starting contact area of the joint touch gesture and the touch-sensitive display unit; and the area B is an ending contact area of the joint touch gesture and the touch-sensitive display unit. The moving track from the area A to the area B is the track of the touch gesture. The electronic device compares the detected track of the joint touch gesture with a preset track, and judges whether the track of the joint touch gesture is matched with the preset track (405). The preset track information may be preset by the electronic device when the electronic device leaves a factory, or may be preset by a user. The preset trajectory information may be saved in a memory (e.g., memory 120 in fig. 1);

illustratively, the predetermined track is a straight line, which may be a horizontal line, a vertical line or a diagonal line (e.g., "-", "|", "/" or "\"). It should be noted that the preset trajectory may be a trajectory in other forms, and may be adaptively adjusted according to specific design requirements. In the embodiment of the present invention, the preset track is taken as an example of a straight line, and does not limit the scheme of the present invention.

FIG. 5 is an exemplary user interface with a joint touch gesture traced as a horizontal line (e.g., "-") according to an embodiment of the present invention. For example: the joint touch position detected at the beginning is in the area a (the area a is a start contact area) and then the joint touch position is detected to move to the area B (the area B is an end contact area), and the track of the joint touch gesture is the track moving from the area a to the area B. The arrow direction is the moving direction of the joint touch gesture from zone a to zone B, as indicated by the horizontal line trace shown by the dotted line. And the electronic equipment compares the detected transverse line track with a preset straight line track and judges that the transverse line track is matched with the preset track.

In some embodiments, if it is determined that the trajectory of the joint touch gesture matches a preset trajectory, a text selection area is displayed on the text application interface in response to the joint touch gesture (406).

The text selection area is located between a first endpoint and a second endpoint, the first endpoint is located at a first position in the text application interface, and the second endpoint is located at a second position in the text application interface. For example: after the track of the joint touch gesture is judged to be matched with a preset track, inserting a first endpoint at the position of a starting contact area A of the joint touch gesture and the touch-sensitive display unit, and inserting a second endpoint at the position of an ending contact area B of the joint touch gesture and the touch-sensitive display unit; the insertion position of the first endpoint is a first position, which may be the beginning or end of a text word or word in a text application interface displayed by the display that is closest to the centroid of the region a; the insertion position of the second endpoint is a second position, which may be the beginning or end of a text word or word in the text application interface displayed by the display that is closest to the centroid of the region B; and a text region positioned between the first endpoint and the second endpoint in the text application interface is the text selection region.
