Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a method and device for starting an application. Background Art

[0002] If the device is not used for a long time, the system will enter low power mode and the display will turn off to save power. If the user has set up security authentication, the device will automatically enter the lock screen state when the screen is off. If the screen needs to be turned on, password verification and other operations are required before entering the system desktop.

[0003] In order to quickly wake up some commonly used applications when the screen is off, some manufacturers have launched a quick wake-up function to quickly start specific applications in a short time and achieve more convenient human-computer interaction. However, since the quick wake-up function in the off-screen state cannot take into account identity information recognition at the same time, when entering applications involving personal privacy such as address books, chat software, and photo albums, security authentication is required again, which cannot achieve a smooth user experience. Summary of the invention

[0004] The present application provides an application startup method and device. When the terminal device is turned off and locked, the user can quickly start a specific application with only one operation, which takes into account both security and convenience and brings a smooth interactive experience to the user.

[0005] In a first aspect, a method for launching an application is provided, the method comprising: in a first interface of a terminal device, obtaining a first movement trajectory of a user on a screen of the terminal device, the first movement trajectory passing through a fingerprint sensing area of ​​the terminal device, the first interface being an interface of the terminal device in an off-screen and locked state; in response to the first movement trajectory, presenting a second interface, the second interface being an interface of an application corresponding to the first movement trajectory.

[0006] The present application provides an application startup method. The user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be obtained while obtaining the movement trajectory. The user can quickly start a specific application with only one operation, which takes into account both security and convenience and brings a smooth interactive experience to the user.

[0007] The first interface includes, but is not limited to, an interface where the terminal device has a completely black screen, an interface where the terminal device only displays the time in a black screen state, an interface where the terminal device only displays the date in a black screen state, an interface where the terminal device only displays a specified image in a black screen state, an interface where the terminal device only displays a music progress bar in a black screen state, and an interface where the terminal device only displays volume control in a black screen state. Optionally, the time on the interface may be in digital form or in graphic form, such as time displayed in the form of a clock. Optionally, the first interface may also be a combination of the above-mentioned multiple display interfaces, for example, the first interface may be an interface where the terminal device only displays the time and date in a black screen state, or the first interface may be an interface where the terminal device only displays the music progress bar and volume control in a black screen state, and this application does not impose any restrictions on this.

[0008] The fingerprint sensing area is the area of ​​the terminal device's screen that is used to sense the user's fingerprint. When the user's finger is located in the fingerprint sensing area and in contact with the screen, the terminal device can obtain the user's fingerprint, which can be used to unlock the terminal device's system.

[0009] The movement track in the embodiment of the present application includes but is not limited to sliding in different directions, numbers, English characters and special symbols, such as "W", "M", "S", "C", "||", "|", "V", "<", ">", "&", "8", circle, triangle, love, etc. The first movement track, the second movement track, the third movement track, the fourth movement track, and the fifth movement track in the embodiment of the present application are all the above movement tracks.

[0010] This application can pre-set the correspondence between movement tracks and applications. Optionally, one movement track can correspond to one application, or multiple movement tracks can correspond to one application, and this application does not limit this. For example, the movement track "S" corresponds to the launch of the photo album application, the movement tracks "W" and "L" correspond to the quick launch of the address book application, and the movement track "M" corresponds to the launch of the music playback application.

[0011] In a possible implementation scenario, the correspondence between the movement trajectory and the application can also be pre-configured before the terminal device leaves the factory. For example, the user can be informed through the instruction manual, and the user can quickly start a specific application based on the correspondence between the movement trajectory and the application. For example, the movement trajectory "S" corresponds to the start of the photo album application, the movement trajectory "W" and "L" correspond to the quick start of the address book application, and the movement trajectory "M" corresponds to the start of the music player application.

[0012] The second interface is the user interface of the application, including but not limited to the main interface of the application and the sub-interface of the application switched to by buttons on the main interface.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: in the first interface, obtaining a second movement trajectory of the user on the screen, the second movement trajectory passing through the fingerprint sensing area; in response to the second movement trajectory, presenting a third interface, the third interface being a failure prompt interface.

[0014] When the terminal device is in use, the user can enter at least one preset fingerprint and at least one preset movement trajectory. Each preset movement trajectory corresponds to the quick launch of an application. If the similarity between the fingerprint obtained by the terminal device and the preset fingerprint is greater than the first preset matching threshold, it means that the fingerprint match is successful; if the similarity between the fingerprint obtained by the terminal device and the preset fingerprint is less than or equal to the first preset matching threshold, it means that the fingerprint match fails. Similarly, if the similarity between the movement trajectory obtained by the terminal device and the preset movement trajectory is greater than the second preset matching threshold, it means that the movement trajectory match is successful; if the similarity between the movement trajectory obtained by the terminal device and the preset movement trajectory is less than or equal to the second preset matching threshold, it means that the movement trajectory match fails.

[0015] In the case where the fingerprint matching fails, the terminal device may present a third interface. Exemplarily, if the fingerprint matching fails and the second movement track matching fails, the terminal device presents the third interface. Exemplarily, if the fingerprint matching fails but the second movement track matching succeeds, the terminal device presents the third interface.

[0016] In some possible implementations, the third interface may include failure prompt text or failure prompt pattern. For example, the failure prompt text includes but is not limited to "unlock failed", "operation failed", "try again", "error", etc. The failure prompt pattern includes but is not limited to failure animation, "×" symbol, etc.

[0017] The present application provides an application startup method, which can present a third interface when the user's fingerprint matching fails, thereby preventing unauthorized users from using the locked terminal device and ensuring the security and privacy of the terminal device.

[0018] In combination with the first aspect, in some implementations of the first aspect, the third interface includes a fingerprint matching failure prompt interface, a movement trajectory matching failure prompt interface, or a re-input prompt interface.

[0019] The fingerprint matching failure prompt interface may include text prompts such as "fingerprint matching failed", "fingerprint matching error", "input error", "fingerprint recognition failed", "recognition failed", etc., and may also include patterns such as "×".

[0020] The motion trajectory matching failure prompt interface may include text prompts such as "motion trajectory matching failed", "motion trajectory matching error", "input error", "motion trajectory recognition failed", "recognition failed", "gesture recognition failed", etc., and may also include patterns such as "×".

[0021] The prompt re-entry interface may include prompt texts such as "Please re-enter", "Enter again", "Try again", etc., or may directly display a password input button.

[0022] The present application provides an application startup method, which can present a third interface when the user's fingerprint matching fails, thereby preventing unauthorized users from using the locked terminal device and ensuring the security and privacy of the terminal device.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: in the first interface, obtaining a third movement trajectory of the user on the screen, the third movement trajectory passing through the fingerprint sensing area; in response to the third movement trajectory, presenting a fourth interface, the fourth interface being the desktop homepage of the terminal device.

[0024] The desktop homepage of a terminal device is usually the interface that a user sees on the screen when starting the terminal device for the first time. The desktop homepage may include any one or more of application icons, application folders, application widgets, wallpapers, search bars, bottom navigation bars, theme animations, etc.

[0025] When the fingerprint match is successful but the third movement trajectory match fails, the terminal device can present the fourth interface.

[0026] This application provides an application startup method. When the fingerprint match succeeds but the movement track match fails, the terminal device can be safely unlocked and the desktop homepage of the terminal device can be displayed. Compared with the traditional sliding unlock without security protection, fingerprint verification is added, security is improved, and user privacy is protected. At the same time, compared with the traditional unlocking method of pressing fingerprints, this unlocking method is more in line with the user's habit of using mobile phones and can bring better interaction and feedback experience.

[0027] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: under the first interface, obtaining a fourth movement trajectory of the user on the screen, the fourth movement trajectory passing through the fingerprint sensing area; in response to the fourth movement trajectory, presenting a fifth interface, the fifth interface being an application interface displayed by the terminal device before the screen is turned off.

[0028] If the fingerprint match succeeds but the movement track match fails, the terminal device can present the fifth interface. The fifth interface is the application interface displayed on the terminal device screen before the screen is turned off. For example, if the user is viewing the photo album before the screen is turned off, the fifth interface is the user interface of the photo album application. If the user is using a chat application to chat before the screen is turned off, the fifth interface is the user interface of the chat application.

[0029] In a possible implementation scenario, if the time that the terminal device is in the screen-off state is greater than the preset time threshold, then when the fingerprint match is successful but the movement trajectory match fails, the terminal device presents the fourth interface; if the time that the terminal device is in the screen-off state is less than or equal to the preset time threshold, then when the fingerprint match is successful but the movement trajectory match fails, the terminal device presents the fifth interface.

[0030] This application provides an application startup method. When the fingerprint match succeeds but the movement track match fails, the terminal device can be safely unlocked and the application interface used before the terminal device turns off the screen can be displayed. Compared with the traditional sliding unlock without security protection, fingerprint verification is added, security is improved, and user privacy is protected. At the same time, compared with the traditional unlocking method of pressing fingerprints, this unlocking method is more in line with the user's habit of using mobile phones and can bring better interaction and feedback experience.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: in the first interface, obtaining a fifth movement trajectory of the user on the screen, the fifth movement trajectory passing through the fingerprint sensing area; and presenting the first interface in response to the fifth movement trajectory.

[0032] In the case of a fingerprint matching failure, the terminal device may present the first interface. Exemplarily, the fingerprint matching fails and the second movement track matching fails, and the terminal device presents the first interface. Exemplarily, the fingerprint matching fails, but the second movement track matching succeeds, and the terminal device presents the first interface. The terminal device still presents the first interface after acquiring the fifth movement track in the first interface, which can be understood as that the screen of the terminal device is unresponsive when the fingerprint matching fails.

[0033] The present application provides an application startup method, in which a terminal device may not respond in any way when a user's fingerprint matching fails, thereby preventing unauthorized users from using the locked terminal device and ensuring the security and privacy of the terminal device.

[0034] In combination with the first aspect, in some implementations of the first aspect, obtaining a first movement trajectory of a user on the screen of the terminal device includes: obtaining the first movement trajectory of the user on the screen of the terminal device through a single-finger operation or a multi-finger operation.

[0035] It should be understood that the movement trajectory obtained in the embodiments of the present application is not limited to the movement trajectory obtained by a single finger, but can also be the movement trajectory obtained by multi-finger operation. The movement trajectory in the embodiments of the present application includes but is not limited to sliding in different directions, numbers, English characters and special symbols, such as "W", "M", "S", "C", "V", "||", "|", "<", ">", "&", "8", circle, triangle, love, etc.

[0036] For example, the user can obtain movement trajectories such as "W", "M", "S", "C", "V", "|", "<", ">", "&", "8", circle, triangle, and love through single-finger operation. The user can obtain movement trajectories such as "||", "|||", "||||", "LL", "JJ", "ZZ", and love through multi-finger operation.

[0037] The present application provides an application startup method, whereby a user can quickly start a specific application by obtaining a first movement trajectory through a single-finger operation or a multi-finger operation. There are many options for startup gestures, which enrich the types of quickly launched applications.

[0038] In combination with the first aspect, in some implementations of the first aspect, the method further includes: acquiring a correspondence between the first movement trajectory input by the user and the application.

[0039] The user can enter the correspondence between the movement track and the application in advance on the terminal device. Optionally, one movement track can correspond to one application, or multiple movement tracks can correspond to one application, and this application does not limit this. For example, the movement track "S" corresponds to the launch of the photo album application, the movement tracks "W" and "L" correspond to the quick launch of the address book application, and the movement track "M" corresponds to the launch of the music playback application.

[0040] The present application provides an application startup method, in which a user can enter the correspondence between a movement trajectory and an application in advance on a terminal device. Later, when the terminal device is turned off and locked, the user can use a variety of different movement trajectories to open the corresponding application, enriching the types of quick startup applications.

[0041] In combination with the first aspect, in some implementations of the first aspect, the screen of the terminal device is integrated with a fingerprint sensor, and the fingerprint sensor is used to obtain the fingerprint of the user.

[0042] Exemplarily, the fingerprint sensor may be a capacitive fingerprint sensor, an ultrasonic fingerprint sensor, an optical fingerprint sensor, etc., and the fingerprint sensor may be located under the screen of the terminal device. When the user's finger passes over the fingerprint sensing area, the terminal device may obtain the user's fingerprint through the fingerprint sensor.

The user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be obtained while obtaining the movement trajectory. The user can quickly start a specific application with only one operation, which takes into account both security and convenience and brings a smooth interactive experience to the user.

[0044] In combination with the first aspect, in some implementations of the first aspect, the screen of the terminal device is integrated with a touch chip, and the touch chip is used to obtain the first movement trajectory.

[0045] Optionally, the user's movement track on the screen can also be obtained through a fingerprint sensor. In a possible implementation scenario, the screen of the terminal device is integrated with a fingerprint sensor with a large area, and the user's movement track on the screen and the fingerprint can be obtained simultaneously through the fingerprint sensor.

[0046] The present application provides an application startup method. The user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be obtained while obtaining the movement trajectory. The user can quickly start a specific application with only one operation, which takes into account both security and convenience and brings a smooth interactive experience to the user.

[0047] In combination with the first aspect, in certain implementations of the first aspect, presenting the second interface in response to the first moving trajectory includes: obtaining the fingerprint of the user when the first moving trajectory passes through the fingerprint sensing area; and presenting the second interface when the user's fingerprint successfully matches a preset fingerprint and the first moving trajectory successfully matches a preset moving trajectory.

[0048] The user's fingerprint successfully matches the preset fingerprint, indicating that the similarity between the user's fingerprint data obtained by the terminal device and the preset fingerprint is greater than the first preset matching threshold. The first movement trajectory successfully matches the preset movement trajectory, indicating that the similarity between the first movement trajectory obtained by the terminal device and the preset movement trajectory is greater than the second preset matching threshold. The preset fingerprint can be entered in advance by the user in the terminal device. The preset movement trajectory can be entered in advance by the user in the terminal device, or it can be a factory-installed configuration.

[0049] The present application provides an application startup method. The user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be obtained while obtaining the movement trajectory. The user can quickly start a specific application with only one operation, which takes into account both security and convenience and brings a smooth interactive experience to the user.

[0092] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of the present application.

[0093] In the embodiments of the present application, words such as "exemplary" and "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present concepts in a concrete way.

[0094] The business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0095] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0096] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0097] In the present application, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: including the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0098] If the device is not used for a long time, the system will enter low power mode and the display will turn off to save power. If the user has set up security authentication such as password, fingerprint, face, or pattern, the device will automatically enter the lock screen state when the screen is off. If the screen needs to be turned on, password verification and other operations are required before entering the system desktop.

[0099] In order to quickly wake up some commonly used applications when the screen is off, some manufacturers have launched a quick wake-up function to wake up specific applications in a short time to achieve more convenient human-computer interaction. However, since the quick wake-up function in the off-screen state cannot take into account identity information recognition at the same time, when entering applications involving personal privacy such as contacts, chat software, and photo albums, security authentication is required again, and a smooth experience cannot be achieved.

[0100] With the popularization of fingerprint recognition technology in terminal devices, people are gradually accustomed to using fingerprints to unlock the system and enter the desktop. However, currently the fingerprint recognition device is generally separated from the screen and is only used for system unlocking and secure payment.

[0101] How to achieve efficient and secure unlocking and quick application startup at the same time has become an urgent need. In the embodiment of the present application, the user's movement track on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be obtained at the same time as the movement track. The user only needs one operation to quickly start a specific application, taking into account both security and convenience, and bringing a smooth interactive experience to the user.

[0102] The method provided in the embodiments of the present application can be applied to terminal devices such as mobile phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), etc. The embodiments of the present application do not impose any restrictions on the specific types of terminal devices.

[0103] For example, Figure 1 The structure diagram of the terminal device 100 is shown. The terminal device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, an earphone interface 170D, a sensor module 180, a button 190, a motor 191, an indicator 192, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, an air pressure sensor 180C, a magnetic sensor 180D, an acceleration sensor 180E, a distance sensor 180F, a proximity light sensor 180G, an ultrasonic sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M, etc.

[0104] It is understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the terminal device 100.

[0179] Figure 3 This is an exemplary flowchart of an application startup method provided in an embodiment of the present application.

[0180] 310. In the first interface, obtain a first movement trajectory.

[0181] In the first interface of the terminal device, a first movement track of the user on the screen of the terminal device is obtained. The first movement track passes through the fingerprint sensing area of ​​the terminal device, and the first interface is an interface of the terminal device in a screen-off and locked state.

[0182] Figure 4 It is a schematic diagram of the first interface provided in an embodiment of the present application. Figure 4 (a) is a completely black screen interface of the terminal device. Figure 4 (b) is the interface where the terminal device displays only the date in a black screen state. Figure 4(c) is an interface where the terminal device displays only the time in a black screen state. Figure 4 (d) is an interface where the terminal device displays time in the form of a clock only when the screen is black. Figure 4 (e) is an interface where the terminal device displays only the time and date in a black screen state. Figure 4 (f) is an interface where the terminal device displays only the specified image in a black screen state. Figure 4 (g) is an interface where the terminal device displays only the music progress bar and volume control in a black screen state. Figure 4 (h) is an interface where the terminal device displays only the music progress bar, volume control, time and date in a black screen state. Figure 4 (i) is an interface in which the terminal device displays only the date and the time in the form of a clock in a black screen state. It should be understood that Figure 4 The first interface is only an example. The first interface may also include Figure 4 (a) to Figure 4 The combination of elements displayed on the interface in (i), for example, the first interface can be an interface in which the terminal device only displays the time, date and a specified image when the screen is black, and the first interface can also be an interface in which the terminal device only displays a help button when the screen is black. The above examples should not be construed as limitations on the present application.

[0183] The fingerprint sensing area is the area of ​​the terminal device's screen that is used to sense the user's fingerprint. When the user's finger is located in the fingerprint sensing area and in contact with the screen, the terminal device can obtain the user's fingerprint, which can be used to unlock the terminal device's system.

[0184] 320 , in response to the first movement trajectory, present a second interface.

[0185] In response to the first movement trajectory, a second interface is presented on the screen of the terminal device, and the second interface is an interface of the application corresponding to the first movement trajectory.

[0186] In a possible implementation, when the user fingerprint acquired by the terminal device successfully matches the preset fingerprint and the first movement trajectory successfully matches the preset movement trajectory, the second interface is presented.

[0187] The first moving trajectory includes, but is not limited to, sliding along different directions, numbers, English characters and special symbols, such as "W", "M", "S", "C", "||", "|", "V", "<", ">", "&", "8", circle, triangle, love, etc. The present application can pre-set the correspondence between the moving trajectory and the application. Optionally, one moving trajectory can correspond to one application, or multiple moving trajectories can correspond to one application, and the present application does not limit this. In a possible implementation scenario, the correspondence between the moving trajectory and the application can also be pre-configured before the terminal device leaves the factory. For example, the user can be informed through the instruction manual, and the user can quickly start a specific application based on the correspondence between the moving trajectory and the application. Exemplarily, the moving trajectory "S" corresponds to the launch of the photo album application, the moving trajectories "W" and "L" correspond to the quick launch of the calculator application, the moving trajectory "6" corresponds to the launch of the text message application, and the moving trajectory "V" corresponds to the launch of the chat application.

[0188] The second interface is the user interface of the application, including but not limited to the main interface of the application and the sub-interface of the application switched to by buttons on the main interface.

[0189] Figure 5 This is a schematic diagram of presenting a second interface in response to a first movement trajectory provided by an embodiment of the present application. The terminal device obtains the user's first movement trajectory "S" under the first interface, the fingerprint and the first movement trajectory are successfully matched, and the second interface is presented. The second interface is the user interface of the album application.

[0190] Figure 6 This is another schematic diagram of presenting a second interface in response to a first movement trajectory provided in an embodiment of the present application. The terminal device obtains the user's first movement trajectory "W" under the first interface, and the fingerprint and the first movement trajectory are successfully matched, and the second interface is presented. The second interface is the user interface of the counter application.

[0191] Figure 7 This is another schematic diagram of presenting a second interface in response to a first movement trajectory provided in an embodiment of the present application. The terminal device obtains the user's first movement trajectory "6" under the first interface, and the fingerprint and the first movement trajectory are successfully matched, and the second interface is presented. The second interface is the user interface of the SMS application.

[0192] Figure 8 This is another schematic diagram of presenting a second interface in response to a first movement trajectory provided in an embodiment of the present application. The terminal device obtains the user's first movement trajectory "V" under the first interface, and the fingerprint and the first movement trajectory are successfully matched, and the second interface is presented. The second interface is the user interface of the chat application.

[0193] Fig. 9It is a schematic diagram of the movement trajectory provided in the embodiment of the present application.

[0194] The first moving trajectory, the second moving trajectory, the third moving trajectory, the fourth moving trajectory, and the fifth moving trajectory in the embodiment of the present application may be collectively referred to as moving trajectories.

[0195] The moving trajectory in the embodiments of the present application includes but is not limited to sliding in different directions, numbers, English characters and special symbols, such as "W", "M", "S", "C", "||", "|", "V", "<", ">", "&", "8", circle, triangle, love, etc. Fig. 9 The pattern in each grid can be a moving track, that is, the user can draw the pattern in the grid on the screen when the terminal device is turned off and locked to quickly start the corresponding application. It should be understood that Fig. 9 The moving track patterns in the figure are only examples and should not be construed as limitations on the present application.

[0196] Fig.10 This is a schematic diagram of a movement trajectory obtained by a user through a single-finger operation or a multi-finger operation provided in an embodiment of the present application.

[0197] When the terminal device is in the state of turning off the screen and locking it, the user can slide on the screen using a single finger or multiple fingers, and the terminal device will collect the movement track and fingerprint obtained by the user sliding on the screen. Fig.10 In (a), the user obtains the moving trajectory of the triangle through single-finger operation; Fig.10 In (b), the user obtains a “W”-shaped moving trajectory through single-finger operation; Fig.10 In (c), the user obtains a moving trajectory in the shape of “|||” through three-finger operation; Fig.10 In (d), the user obtains a heart-shaped moving trajectory through two-finger operation.

[0198] Fig.11 It is a schematic diagram of the movement trajectory and identification area provided in the embodiment of the present application.

[0199] The terminal device obtains the user's fingerprint through the fingerprint sensing area and obtains the user's movement trajectory through the movement trajectory recognition area. The fingerprint sensing area and the movement trajectory recognition area can be the same area or different areas.

[0200] For example, the fingerprint sensor can simultaneously realize the identification of fingerprints and movement trajectories, and the screen of the terminal device can be integrated with the fingerprint sensor to simultaneously obtain the user's fingerprint and movement trajectory in the area on the screen where the fingerprint sensor acts. In this case, the area on the screen where the fingerprint sensor acts is both the fingerprint sensing area and the movement trajectory identification area.

[0201] Exemplarily, fingerprint recognition can be realized by a fingerprint sensor, and movement trajectory recognition can be realized by a touch chip. The screen of the terminal device can integrate both a fingerprint sensor and a touch chip, so as to obtain the user's fingerprint in the area on the screen where the fingerprint sensor acts, and obtain the user's movement trajectory in the area on the screen where the touch chip acts. At this time, the area on the screen where the fingerprint sensor acts is the fingerprint sensing area, and the area where the touch chip acts is the movement trajectory recognition area. It should be understood that when the fingerprint sensing area and the movement trajectory recognition area are different areas, the two areas may be in a containing relationship, a partially overlapping relationship, or a separated relationship.

[0202] The starting position of the mobile trajectory can be in the fingerprint sensing area, the mobile trajectory recognition area or the non-recognition area, and the end position of the mobile trajectory can be in the fingerprint sensing area, the mobile trajectory recognition area or the non-recognition area. This application does not limit the specific starting position and end position of the mobile trajectory, as long as at least part of the mobile trajectory falls in the mobile trajectory recognition area and the mobile trajectory passes through the fingerprint sensing area. The non-recognition area includes other areas on the screen of the terminal device except the mobile trajectory recognition area and the fingerprint sensing area.

[0203] Fig.11 In (a), the fingerprint sensing area and the movement track recognition area belong to the same area, and the area of ​​the area is smaller than the area of ​​the screen of the terminal device, and the movement track "W" all falls within the area; Fig.11 In (b), the fingerprint sensing area and the movement track identification area belong to the same area, and the area of ​​the area is equal to the area of ​​the screen of the terminal device, and the movement track "○" all falls within the area; Fig.11 In (c), the fingerprint sensing area and the movement track recognition area belong to different areas, the areas of the fingerprint sensing area and the movement track recognition area are both smaller than the area of ​​the screen, the fingerprint sensing area is included in the movement track recognition area, the starting position of the movement track “|” is in the movement track recognition area, and the ending position of the movement track “|” is in the non-recognition area; Fig.11 In (d), the fingerprint sensing area and the movement trajectory recognition area belong to different areas, the area of ​​the movement trajectory recognition area is equal to the area of ​​the screen, the area of ​​the fingerprint sensing area is smaller than the area of ​​the screen, the fingerprint sensing area is included in the movement trajectory recognition area, the starting position of the movement trajectory "W" is in the movement trajectory recognition area, and the end position of the movement trajectory "W" is in the fingerprint sensing area; Fig.11 In (e), the fingerprint sensing area and the movement trajectory recognition area belong to different areas, the areas of the fingerprint sensing area and the movement trajectory recognition area are both smaller than the area of ​​the screen, the fingerprint sensing area and the movement trajectory recognition area are two separate areas, the starting position of the movement trajectory “|” is within the movement trajectory recognition area, and the ending position of the movement trajectory “|” is within the fingerprint sensing area; Fig.11 In (f), the fingerprint sensing area and the mobile trajectory recognition area belong to different areas. The areas of the fingerprint sensing area and the mobile trajectory recognition area are both smaller than the area of ​​the screen. The fingerprint sensing area and the mobile trajectory recognition area partially overlap. The starting position and the terminal position of the mobile trajectory "V" are both in the non-recognition area.

[0204] Fig.12 This is an exemplary flowchart of another application startup method provided in an embodiment of the present application.

[0205] 1210. In the first interface, obtain a second movement trajectory.

[0206] In the first interface of the terminal device, a second movement track of the user on the screen of the terminal device is obtained. The second movement track passes through the fingerprint sensing area of ​​the terminal device.

[0207] For a description of the first interface, see Figure 4 For the description of the second moving trajectory, please refer to Fig. 9 , this application will not repeat it.

[0208] 1220. In response to the second movement trajectory, present a third interface.

[0209] In response to the second movement trajectory, a third interface is presented on the screen of the terminal device, and the third interface is a failure prompt interface.

[0210] In the case where the fingerprint matching fails, the terminal device may present a third interface. Exemplarily, if the fingerprint matching fails and the second movement track matching fails, the terminal device presents the third interface. Exemplarily, if the fingerprint matching fails but the second movement track matching succeeds, the terminal device presents the third interface.

[0211] The third interface may include failure prompt text or failure prompt pattern. For example, the failure prompt text includes but is not limited to "unlock failed", "operation failed", "try again", "error", etc. The failure prompt pattern includes but is not limited to failure animation, "×" symbol, etc.

[0212] The third interface includes a fingerprint matching failure prompt interface, a movement trajectory matching failure prompt interface or a prompt re-entry interface. The fingerprint matching failure prompt interface may include text prompts such as "fingerprint matching failed", "fingerprint matching error", "input error", "fingerprint recognition failed", "recognition failed", etc., and may also include patterns such as "×". The movement trajectory matching failure prompt interface may include text prompts such as "movement trajectory matching failed", "movement trajectory matching error", "input error", "movement trajectory recognition failed", "recognition failed", "gesture recognition failed", etc., and may also include patterns such as "×". The prompt re-entry interface may include prompt texts such as "Please re-enter", "Enter again", "Try again", etc., or it may directly display the password input button.

[0213] Fig.13 The third interface is presented in response to the second movement track provided by the embodiment of the present application. The terminal device obtains the second movement track "6" of the user in the first interface, and the fingerprint matching fails, and the third interface is presented. Fig.13 In (a), the third interface displays a failure prompt text "Slide to unlock"; Fig.13 In (b), the third interface displays the failure prompt text "Use face recognition to unlock XX", "Please face the screen to verify your face" and "Use password"; Fig.13 In (c), the third interface displays a failure prompt pattern “×”; Fig.13 In (d), the third interface displays a failure prompt text "Please enter password" and a password input button; Fig.13 In (e), the third interface displays a failure prompt text "Application quick launch failed, please try again" and a failure prompt pattern; Fig.13 In (f), the third interface displays the failure prompt text "Recognition failed". It should be understood that after the terminal device obtains the user's second movement trajectory in the first interface, the terminal device is not unlocked and the screen displayed on the screen that is different from the first interface can be considered as a failure prompt interface, that is, the third interface, and the third interface is not limited to the above example.

[0214] Fig.14 This is an exemplary flowchart of another application startup method provided in an embodiment of the present application.

[0215] 1410. In the first interface, obtain a third movement trajectory.

[0216] In the first interface of the terminal device, a third movement track of the user on the screen of the terminal device is obtained. The third movement track passes through the fingerprint sensing area of ​​the terminal device.

[0217] For a description of the first interface, see Figure 4 For the description of the third moving trajectory, please refer to Fig. 9, this application will not repeat it.

[0218] 1420 , in response to the third movement trajectory, present a fourth interface.

[0219] In response to the third movement track, a fourth interface is presented on the screen of the terminal device, and the fourth interface is a desktop homepage of the terminal device.

[0220] When the fingerprint match is successful and the third movement trajectory match fails, the terminal device can present the fourth interface.

[0221] The desktop homepage of a terminal device is usually the interface that a user sees on the screen when starting the terminal device for the first time. The desktop homepage may include any one or more of application icons, application folders, application widgets, wallpapers, search bars, bottom navigation bars, theme animations, etc.

[0222] Fig.15 The fourth interface is presented in response to the third movement track provided by the embodiment of the present application. The terminal device obtains the third movement track "8" of the user in the first interface, the fingerprint matching is successful, the third movement track matching fails, and the fourth interface is presented. Fig.15 In (a), the fourth interface includes multiple applications and a bottom navigation bar; Fig.15 In (b), the fourth interface includes a search bar and multiple application widgets; Fig.15 In (c), the fourth interface includes a search bar, multiple application widgets, and multiple application programs; Fig.15 In (d), the fourth interface includes multiple applications, application widgets and a bottom navigation bar; Fig.15 In (e), the fourth interface includes multiple applications, a search bar and a bottom navigation bar; Fig.15 In (f), the fourth interface includes a search bar and multiple applications.

[0223] The method for presenting the fourth interface in response to the third movement trajectory provided in the embodiment of the present application can also be used for the sliding unlocking of the terminal device, which allows the user to safely unlock the device without perceiving the existence of the fingerprint module. Compared with the traditional sliding unlocking without security protection, fingerprint verification is added, which improves security and protects user privacy. At the same time, compared with the traditional unlocking method of pressing the fingerprint, this unlocking method is more in line with the user's habit of using the mobile phone and can bring a better interaction and feedback experience. Optionally, the sliding unlocking can also be combined with the system desktop switching animation to present richer visual effects and enhance the user's unlocking interaction experience.

[0224] Fig.16 This is an exemplary flowchart of another application startup method provided in an embodiment of the present application.

[0225] 1610. In the first interface, obtain a fourth movement trajectory.

[0226] In the first interface of the terminal device, a fourth movement track of the user on the screen of the terminal device is obtained. The fourth movement track passes through the fingerprint sensing area of ​​the terminal device.

[0227] For a description of the first interface, see Figure 4 For the description of the fourth moving trajectory, please refer to Fig. 9 , this application will not repeat it.

[0228] 1620 , in response to the fourth movement trajectory, present a fifth interface.

[0229] In response to the fourth movement trajectory, a fifth interface is presented on the screen of the terminal device, and the fifth interface is an application interface displayed by the terminal device before the screen is turned off.

[0230] If the fingerprint match succeeds and the fourth movement track match fails, the terminal device may present the fifth interface. The fifth interface is the application interface displayed on the screen of the terminal device before the screen is turned off. For example, if the user is viewing the photo album before the screen is turned off, the fifth interface is the user interface of the photo album application. If the user is using a chat application to chat before the screen is turned off, the fifth interface is the user interface of the chat application.

[0231] In a possible implementation scenario, if the time that the terminal device is in the screen-off state is greater than the preset time threshold, then when the fingerprint match is successful but the movement trajectory match fails, the terminal device presents the fourth interface; if the time that the terminal device is in the screen-off state is less than or equal to the preset time threshold, then when the fingerprint match is successful but the movement trajectory match fails, the terminal device presents the fifth interface.

[0232] Fig.17 This is a schematic diagram of presenting a fifth interface in response to a fourth movement trajectory provided by an embodiment of the present application. The terminal device obtains the user's fourth movement trajectory "L" in the first interface, the fingerprint match is successful, the fourth movement trajectory match fails, and the screen off time is less than or equal to the preset time threshold, and the fifth interface is presented. Fig.17 In (a), the fifth interface is the user interface of the camera application displayed on the screen before the screen is turned off; Fig.17 In (b), the fifth interface is the user interface of the photo album application displayed on the screen before the screen is turned off; Fig.17 In (c), the fifth interface is the user interface of the memo application displayed on the screen before the screen is turned off.

[0233] The method for presenting the fifth interface in response to the fourth movement trajectory provided in the embodiment of the present application can also be used for the sliding unlocking of the terminal device, which allows the user to safely unlock the device without perceiving the existence of the fingerprint module. Compared with the traditional sliding unlocking without security protection, fingerprint verification is added, which improves security and protects user privacy. At the same time, compared with the traditional unlocking method of pressing the fingerprint, this unlocking method is more in line with the user's habit of using the mobile phone and can bring a better interaction and feedback experience. Optionally, the sliding unlocking can also be combined with the system desktop switching animation to present richer visual effects and enhance the user's unlocking interaction experience.

[0234] Fig.18 This is an exemplary flowchart of another application startup method provided in an embodiment of the present application.

[0235] 1810. In the first interface, obtain a fifth moving trajectory.

[0236] In the first interface of the terminal device, a fifth movement track of the user on the screen of the terminal device is obtained. The fifth movement track passes through the fingerprint sensing area of ​​the terminal device.

[0237] For a description of the first interface, see Figure 4 For the description of the fifth moving trajectory, please refer to Fig. 9 , this application will not repeat it.

[0238] 1820 , in response to the fifth movement track, presenting the first interface.

[0239] In response to the fifth movement trajectory, a first interface is presented on the screen of the terminal device, where the first interface is an interface of the terminal device in a screen-off and locked state.

[0240] In the case of a fingerprint matching failure, the terminal device may present the first interface, that is, the screen display remains unchanged. Exemplarily, the fingerprint matching fails and the fifth movement track matching fails, and the terminal device presents the first interface. Exemplarily, the fingerprint matching fails, but the fifth movement track matching succeeds, and the terminal device presents the first interface.

[0241] Fig.19 The first interface is presented in response to the fifth movement track provided by the embodiment of the present application. The terminal device obtains the fourth movement track "M" of the user in the first interface, and the fingerprint matching fails, and the first interface is still presented. Fig. 20 This is another schematic diagram of presenting the first interface in response to the fifth movement trajectory provided by an embodiment of the present application. The terminal device obtains the fourth movement trajectory "N" of the user in the first interface, and the fingerprint matching fails, and the first interface is still presented.

[0242] Fig.21This is an exemplary flowchart of another application startup method provided in an embodiment of the present application.

[0243] 2110, the user enters a preset fingerprint and a preset movement trajectory.

[0244] When the terminal device is in use, the user can enter at least one preset fingerprint and the corresponding relationship between at least one preset movement track and an application. Each preset movement track corresponds to the quick launch of an application. For example, the preset movement track "S" corresponds to the quick launch of the photo album application, the preset movement track "W" corresponds to the quick launch of the address book application, and the preset movement track "C" corresponds to the quick launch of the music player application.

[0245] In a possible implementation, the process of a user entering a preset fingerprint is as follows: (1) the user opens a settings application on the terminal device; (2) finds "Security and Privacy" or a similar option in the settings; (3) selects a related option such as "Fingerprint Recognition" or "Fingerprint and Password"; (4) the system may require the user to enter a device password or pattern to confirm the identity; (5) the user selects "Add Fingerprint" or a similar option; (5) the user follows the instructions on the screen and gently places the finger on the fingerprint sensor multiple times until the system successfully enters the fingerprint, which is not limited to a complete fingerprint but may also be a part of a fingerprint, such as a fingerprint on a fingertip.

[0246] In a possible implementation, the process of a user entering the relationship between a preset movement trajectory and an application is as follows: (1) the user opens the settings application on the terminal device; (2) finds relevant options such as "Accessibility" or "Gesture Control" in the settings; (3) selects "Add Gesture" or a similar option; (4) the user can customize the preset movement trajectory and the associated application. The customized preset movement trajectory can be, for example, letters, numbers, or symbols, and the user can select the application associated with the preset movement trajectory, such as "S" associated with the photo album application, "W" associated with the address book application, and "C" associated with the music playback application.

[0247] 2120, the collection module collects fingerprints and movement trajectories.

[0248] In the first interface of the terminal device, the terminal device collects the user's fingerprint and the user's movement track on the screen.

[0249] The first interface is the interface of the terminal device in the screen-off and locked state. The screen-off and locked state of the terminal device means that when the user is inactive for a period of time, the device screen will be turned off to save power, and the screen will be locked to prevent unauthorized access.

[0250] For example, the user's fingerprint can be collected through a fingerprint sensor, and the user's movement track on the screen can be collected through a fingerprint sensor or TPIC. Optionally, the fingerprint sensor can be a capacitive fingerprint sensor, an ultrasonic fingerprint sensor, an optical fingerprint sensor, etc.

[0251] It should be understood that when the user's finger slides on the screen, it is not required that all track points of the movement trajectory are within the fingerprint sensing area, but the finger's movement trajectory must pass through the fingerprint sensing area at least once to collect fingerprint data and ensure subsequent fingerprint verification.

[0252] In a possible implementation, the terminal device can remind the user that if the user wants to quickly wake up a specified application in the locked state, the finger movement trajectory must pass through the fingerprint sensing area of ​​the screen, and circle the fingerprint sensing area on the user interface to remind the user, such as Fig. 22 shown.

[0253] It should be understood that in the embodiments of the present application, there is no special requirement for the order of collecting movement trajectories and fingerprints, and they can be collected in parallel or sequentially.

[0254] For detailed description of movement track, fingerprint sensing area and movement track recognition area, please refer to Figures 9 to 11 The description is not repeated in this application.

[0255] 2130, presenting the first interface, the second interface, the third interface, the fourth interface or the fifth interface.

[0256] The user fingerprint collected in step 2120 is matched with the fingerprint entered by the user in step 2110. If the similarity between the fingerprint collected by the terminal device and the preset fingerprint is greater than the first preset matching threshold, it indicates that the fingerprint matching is successful; if the similarity between the fingerprint collected by the terminal device and the preset fingerprint is less than or equal to the first preset matching threshold, it indicates that the fingerprint matching fails. In the case where multiple user fingerprints are collected (for example, the user operates with multiple fingers), as long as there is a fingerprint with a similarity greater than the first preset matching threshold with the fingerprint entered by the user in step 2110, the fingerprint matching is successful, otherwise the fingerprint matching fails.

[0257] The movement trajectory collected in step 2120 is matched with the preset movement trajectory entered by the user in step 2110. If the similarity between the movement trajectory collected by the terminal device and the preset movement trajectory is greater than the second preset matching threshold, it indicates that the movement trajectory matching is successful; if the similarity between the movement trajectory collected by the terminal device and the preset movement trajectory is less than or equal to the second preset matching threshold, it indicates that the movement trajectory matching fails.

[0258] Fig.23It is a schematic diagram of a terminal device provided in an embodiment of the present application presenting different interfaces in response to a moving trajectory. The terminal device obtains the user's moving trajectory "W" in the first interface, and the fingerprint matching is successful and the moving trajectory matching is successful, and the second interface is presented; the terminal device obtains the user's moving trajectory "W" in the first interface, and the fingerprint matching fails. Regardless of whether the moving trajectory is successfully matched, the third interface or the first interface is presented; the terminal device obtains the user's moving trajectory "W" in the first interface, and the fingerprint matching is successful and the moving trajectory matching fails, and the fourth interface or the fifth interface is presented. At this time, the user's operation is equivalent to fingerprint unlocking while sliding the screen. In a possible implementation scenario, if the terminal device is in the off-screen state for a time greater than a preset time threshold, then in the case where the fingerprint matching is successful but the moving trajectory matching fails, the terminal device presents the fourth interface, and if the terminal device is in the off-screen state for a time less than or equal to the preset time threshold, then in the case where the fingerprint matching is successful but the moving trajectory matching fails, the terminal device presents the fifth interface.

[0259] For descriptions of the first interface, the second interface, the third interface, the fourth interface, and the fifth interface, see Figures 4 to 9 , Fig.13 , Fig.15 , Fig.17 and Fig.19 , this application will not repeat it.

[0260] In some possible implementations, if the number of fingerprint matching failures exceeds a preset threshold, the terminal device may be set to enter a lost mode.

[0261] Fig.24 This is an exemplary flowchart of another application startup method provided in an embodiment of the present application.

[0262] 2410, a finger is detected falling on the screen.

[0263] When the terminal device is in the screen-off and locked state, when the user's finger falls on the track recognition area or the fingerprint sensing area, execute step 2420.

[0264] 2420, collect fingerprints and movement trajectories.

[0265] When the terminal device is off and locked, the user can slide on the screen with one or more fingers. The terminal device will collect the user's fingerprint and the user's movement track on the screen. That is, the terminal device can collect the fingerprint of one or more fingers and collect the movement track obtained by the user through single-finger operation or multi-finger operation.

[0266] For example, the user's fingerprint can be collected through a fingerprint sensor, and the user's movement track on the screen can be collected through a fingerprint sensor or a touch panel integrated circuit (TPIC). The fingerprint sensor can be a capacitive fingerprint sensor, an ultrasonic fingerprint sensor, an optical fingerprint sensor, etc.

[0267] In one possible implementation, the terminal device can use a large-area fingerprint sensor to collect the user's fingerprint while collecting the movement trajectory of the user's finger, so that the system can be unlocked with one operation and the pre-set application can be directly started, which takes into account both security and convenience and brings a smooth interactive experience to the user.

[0268] For detailed description of movement track, fingerprint sensing area and movement track recognition area, please refer to Figures 9 to 11 The description is not repeated in this application.

[0269] 2430, determine whether the fingerprint matches.

[0270] The terminal device matches the user fingerprint collected in step 2420 with the preset fingerprint.
