Description

Technical Field

[0001] The present invention relates to a new generation of information technology for reading and analyzing graphic data, and in particular to a method and an intelligent terminal for preventing children from being addicted to games. Background Art

[0002] With the rapid pace of modern life, in order to relieve stress and provide entertainment, more and more people use smart terminals such as smartphones and tablets to play games to relax and have fun. In the digital age, games have also become a part of children's lives that they often come into contact with. However, some children are prone to indulge in games, which has a negative impact on their academic performance and physical and mental health; in addition, children lack sufficient judgment and price awareness, and use the payment function to buy skins, props or gifts in the game at will, causing waste. Although some games provide functions such as registering accounts based on ID numbers and distinguishing between children and adults based on real-name registration, and limiting children's game time on this basis; however, children may use adults' phone numbers, ID numbers or names to register game accounts, or use adult registered game accounts to enter the game. It is difficult for smart terminals to distinguish whether the current player is a child, making it difficult for children's game restriction functions to work. Summary of the invention

[0003] In order to solve the technical problems in the prior art that it is difficult for smart terminals for providing game functions to accurately distinguish between children and adults, resulting in the difficulty in taking effect on the game restriction function for children, the present invention provides a method and smart terminal for preventing children from becoming addicted to games. The smart terminal associates game account information with player individual identification information and player physical feature information, uses the player physical feature information to distinguish whether the game account corresponds to a child player or an adult player, and matches the game account information according to the player individual identification information. The effect of accurately and effectively preventing children from becoming addicted to games is achieved.

[0004] In order to achieve this object, the present invention adopts the following technical scheme.

[0005] A method for preventing children from becoming addicted to games, the method being used for a smart terminal that uses a game account to execute a game function, the method comprising the steps of:

[0006] A. During the game account creation process, obtain the player's individual identification information and physical characteristics information, associate the game account information with the player's individual identification information and physical characteristics information, and use the player's physical characteristics information to distinguish whether the game account corresponds to a child player or an adult player;

[0007] B. When using a game account, match the game account information with the player's individual identification information, and take anti-addiction measures for game accounts belonging to child players based on the player identification results of the game account.

[0008] In addition, in the method for preventing children from becoming addicted to games of the present invention, the player's physical characteristic information includes the player's arm length information. After obtaining the player's arm length information, the player's arm length information is used to distinguish whether the game account corresponds to a child player or an adult player based on the arm length distribution range of children and adults and a predetermined confidence range.

[0009] In addition, in the method for preventing children from being addicted to games of the present invention, the player individual identification information includes the player's thumb fingerprint information; during the game account establishment process, the player is prompted to press the fingerprint identification area of ​​the smart terminal with his thumb to obtain the player's thumb fingerprint information; during the game account use process, the game account information is matched according to the player individual identification information according to the game account use start-up and game account use implementation stages, including:

[0010] In the game account use start-up phase, the game account use is started using the player's thumb fingerprint information. If the player's thumb fingerprint information cannot match the stored player's thumb fingerprint information associated with the game account information, the game account use is not started;

[0011] During the game account usage implementation phase, the fingerprint recognition area of ​​the smart terminal is set as the game common button area. The player's thumb fingerprint information is collected in this game common button area at a predetermined time interval and matched with the game account information. If the player's thumb fingerprint information cannot match the stored player's thumb fingerprint information associated with the game account information, the game account will be exited.

[0012] In addition, in the method for preventing children from becoming addicted to games of the present invention, the anti-addiction measures for games include limiting the time period for using a game account, limiting the duration for using a game account, limiting the level range of a game account, limiting the attribute range of a game account, limiting the functional range of a game account, limiting the payment function or payment amount of a game account, or one or more of the above.

[0013] In addition, in the method for preventing children from becoming addicted to games of the present invention, obtaining the player's arm length information comprises the steps of:

[0014] A01. Prompt the player's avatar area on the screen of the smart terminal, and prompt the player to straighten his forearm to establish a game account on the screen; turn on the front camera of the smart terminal, and when the front camera captures the player's facial image in the prompt player avatar area, identify and record the feature position in the player's avatar area, and use the height sensor and angle sensor in the smart terminal to record the pitch angle and height of the smart terminal;

[0015] A02. Repeat step A01 for multiple times. Each time step A01 is executed, the player portrait area is changed to a different horizontal position on the smart terminal screen relative to the previous execution of step A01. During the multiple executions of step A01, the characteristic position in the player portrait area, the pitch angle and the height of the smart terminal are recorded each time.

[0016] A03. Calculate the player's arm length information by using the characteristic positions in the player's head portrait area recorded multiple times, the pitch angle and height of the smart terminal.

[0017] In particular, in the method for preventing children from becoming addicted to games of the present invention, during each execution of step A01, on the fingerprint recognition area of ​​the screen of the smart terminal, the player is prompted to press the fingerprint recognition area with his thumb, and the fingerprint recording function of the fingerprint recognition area of ​​the smart terminal is used to start the fingerprint registration function during each execution of step A01 to record partial fingerprint information of the player's thumb; after executing step A01 multiple times to record partial fingerprint information of the player's thumb, the partial fingerprint information of the player's thumb recorded multiple times is spliced ​​in step A03, and if the splicing result reaches the completeness standard of fingerprint registration, the thumb fingerprint information of the splicing result is recorded as the player's individual identification information; otherwise, the player is prompted to press the fingerprint recognition area with his thumb again, the fingerprint registration function is continued to be started, partial fingerprint information of the player's thumb is recorded and added to the splicing, until the splicing result reaches the completeness standard of fingerprint registration.

[0018] In particular, in the method for preventing children from becoming addicted to games of the present invention, when the front camera captures a player avatar located in the player avatar prompt area, identifying and recording the characteristic position in the player avatar area includes taking the midpoint of the binocular line in the player's facial image in the player avatar area as the characteristic position, and recording the coordinate value of the characteristic position.

[0019] In particular, in the method for preventing children from being addicted to games of the present invention, in step A01, when the front camera captures the player's facial image in the area prompting the player's avatar, the horizontal distance of the symmetrical position of the player's body trunk relative to the characteristic position is identified. When the ratio of the horizontal distance of the symmetrical position of the player's body trunk to the characteristic position exceeds the predetermined threshold range, it is determined that the smart terminal is not located directly in front of the player, and the player is prompted by the smart terminal to place the smart terminal directly in front of the player to recapture the player's facial image; when the ratio of the horizontal distance of the symmetrical position of the player's body trunk to the characteristic position is within the predetermined threshold range, it is determined that the smart terminal is located directly in front of the player, and other operations of step A01 are continued to be executed; and in step A02, for some or all of the executions of step A01, the horizontal distance of the symmetrical position of the player's body trunk relative to the characteristic position is identified, and a judgment is made as to whether the smart terminal is located directly in front of the player. According to the judgment result, the player is prompted by the smart terminal to place the smart terminal directly in front of the player to recapture the player's facial image.

[0020] The present invention also provides a smart terminal for preventing children from getting addicted to games. The smart terminal can use a game account to execute game functions. The smart terminal includes a game account establishment module and a game account use module. The account establishment module includes an account information unit, a player individual identification information acquisition unit, a player physical feature information acquisition unit, and a player differentiation unit.

[0021] The player individual identification information acquisition unit is used to acquire the player individual identification information; the player physical characteristic information acquisition unit is used to acquire the player physical characteristic information; the account information unit is used to establish or record the game account information; the player distinguishing unit is used to distinguish whether the game account corresponds to a child player or an adult player using the player physical characteristic information; the game account establishing module associates the game account information with the player individual identification information and the player physical characteristic information;

[0022] The game account usage module is used to match game account information according to the player's individual identification information during the use of game accounts on smart terminals, and to take game addiction prevention measures for game accounts belonging to child players based on the player differentiation results of the game accounts.

[0023] In particular, in the smart terminal for preventing children from indulging in games of the present invention, the player individual identification information acquisition unit includes a fingerprint recognition module of the smart terminal, and the player individual identification information includes the player's thumb fingerprint information; the game account establishment module is used to prompt the player to press the fingerprint recognition area of ​​the smart terminal with his thumb to obtain the player's thumb fingerprint information; the game account use module is used to match the game account information according to the player individual identification information according to the game account use start-up and game account use implementation stages during the game account use process;

[0024] The player's body feature information acquisition unit includes a front camera of the smart terminal, a height sensor and an angle sensor in the smart terminal; the player's body feature information acquisition unit is used to prompt the player's avatar area at different horizontal positions on the screen of the smart terminal for multiple times, and prompt the player to straighten his forearm to establish a game account on the screen, turn on the front camera of the smart terminal, and when the front camera captures the player's facial image in the prompt player avatar area, identify and record the characteristic position in the player's avatar area, and use the height sensor and angle sensor in the smart terminal to record the pitch angle height of the smart terminal; the player's body feature information acquisition unit is also used to use the characteristic positions in the player's avatar area recorded multiple times, the pitch angle and height of the smart terminal to infer the player's arm length information as the player's body feature information.

[0025] The beneficial technical effects of the present invention include the following.

[0026] (1) By using the hardware functions of common smart terminals to obtain the player's individual identification information and physical characteristics information, a method for preventing children from becoming addicted to games is implemented. There is no need to upgrade the hardware structure of the smart terminal itself, so the method has a wide range of applications and is easy to put into practical use.

[0027] (2) Through the camera function and the sensor function of the smart terminal, the player's head portrait or the specific position of the player's face on the smart terminal screen is cleverly used, and the corresponding relationship between the horizontal height and pitch angle of the smart terminal is used to determine the player's arm length information using geometric calculation methods. This is used to distinguish whether the game account corresponds to an adult player or a child player. Compared with methods such as facial feature recognition to distinguish between adult players and child players, this method has higher credibility and is more accurate.

[0028] (3) The present invention obtains the player's individual identification information when collecting the player's physical feature information. That is, the player's thumb is required to be kept pressed in the fingerprint recognition area of ​​the smart terminal before the front camera of the smart terminal is used to recognize the player's facial image to determine the player's arm length. This can effectively prevent children from deceiving the smart terminal, for example, by using a selfie stick or with the help of others to enable the smart terminal to obtain "false" arm length information.

[0029] (4) During the use of a game account, the game account information shall be matched according to the player’s individual identification information, in accordance with the stages of starting the game account use and implementing the game account use. This can prevent children from impersonating an adult’s account to start or run the game, and ensure that the function of preventing children from becoming addicted to games is truly implemented.

[0030] (5) In order to improve the accuracy of player identification, the player's front body and facial graphics can be accurately captured by identifying the position of the smart terminal in front of the player, thereby improving the calculation accuracy of the player's arm length information.

[0031] (6) The method of preventing children from becoming addicted to games of the present invention can be implemented as an independent function as a bottom-level function of a smart terminal, or can be embedded as a part of a game. It has a high degree of autonomy and is easy to implement.

[0032] (7) The method and intelligent terminal for preventing children from becoming addicted to games of the present invention can truly prevent children from becoming addicted to games, thereby ensuring the physical and mental health and academic progress of children, and having a good social influence and positive social effect.

[0042] Figure 4 The flowchart of a method for preventing children from getting addicted to games according to a specific embodiment of the present invention is shown in the figure. As shown in the figure, a method for preventing children from getting addicted to games is provided in a specific embodiment of the present invention. The method is used for a smart terminal, such as a smart phone or a tablet computer, that uses a game account to perform game functions. The method comprises the following steps:

[0043] A. During the game account creation process, obtain the player's individual identification information and physical characteristics information, associate the game account information with the player's individual identification information and physical characteristics information, and use the player's physical characteristics information to distinguish whether the game account corresponds to a child player or an adult player;

[0044] B. When using a game account, match the game account information with the player's individual identification information, and take anti-addiction measures for game accounts belonging to child players based on the player identification results of the game account.

[0045] The game account may include the game player ID, nickname, or player mobile phone number, player WeChat account or player ID card ID, name and other fields that can distinguish game players, and the specific implementation of the present invention does not make special distinctions. Generally speaking, if it is an online game, the server will store various attributes, equipment, game progress, game results and other data corresponding to the game account, and the smart terminal will store part of the game data; if it is a stand-alone game, the smart terminal will store various attributes, equipment, game progress, game results and other data corresponding to the game account, and the specific implementation of the present invention is applicable to both cases.

[0046] The first stage of the specific implementation method of the present invention is the game account establishment stage. At this time, the smart terminal will obtain the player's individual identification information and the player's physical characteristic information according to the method of the present invention, and associate the game account information with the player's individual identification information and the player's physical characteristic information, wherein the player's physical characteristic information is used to distinguish whether the game account corresponds to a child player or an adult player.

[0047] The second stage of the specific implementation method of the present invention is the game account use stage. At this time, the smart terminal will run the game according to the player's individual identification information matching the game account information, and further adopt game anti-addiction measures for game accounts belonging to child players based on the player differentiation results of the game account.

[0048] Therefore, in the specific implementation of the present invention, two key information are used to associate with the game account - the player's individual identification information and the player's physical characteristic information. The player's individual identification information is used to ensure the correspondence between the player and the account, that is, to ensure that child players cannot use adult accounts to run games; at the same time, it can ensure that the real player's physical characteristic information is obtained. The player's physical characteristic information can distinguish whether the game account corresponds to a child player or an adult player. Therefore, in the specific implementation of the present invention, the method of distinguishing objects is adopted - for the more difficult to achieve player's physical characteristic information acquisition and category identification, it is implemented in the game account establishment stage, and it only needs to be implemented once during the validity period of the game account; and for the more commonly achieved player individual identification information and game account information matching, it is implemented throughout the game account use stage, and consistently prevents children from becoming addicted to games.

[0049] The method for preventing children from being addicted to games in the specific implementation manner of the present invention can be a background management program of a smart terminal, which has a higher priority than the game. When the smart terminal enables the game program, the method for preventing children from being addicted to games is first loaded into the process of the smart terminal. It can also be embedded in the game itself and exist continuously as a management process of the game. Therefore, the specific implementation manner of the present invention has the advantage of wide applicability.

[0050] In addition, in the method for preventing children from becoming addicted to games in a specific embodiment of the present invention, the player's physical characteristic information includes the player's arm length information. After obtaining the player's arm length information, the player's arm length information is used to distinguish whether the game account corresponds to a child player or an adult player based on the arm length distribution range of children and adults and a predetermined confidence range.

[0051] Compared with recognizing facial features of game players to distinguish their ages, or recognizing body proportion features to distinguish their ages, it is easier to measure player arm length information using smart terminals. It does not require complex algorithms and artificial intelligence, and is more accurate and reliable.

[0052] Generally speaking, the relationship between a person's height and arm span is basically equal. Arm length is also generally positively correlated with age. For example, for children aged 6 to 7, the typical arm length (inside) is 33 to 34 cm; for children aged 7 to 8, the typical arm length (inside) is 35 to 36 cm; a normal distribution will be formed around this range based on the number of samples; and in the specific implementation of the present invention, what is actually measured is the distance between the front camera of the smart terminal held by the player and the target point on the face, so the holding length will be increased by 2 to 5 cm to this value.

[0053] The predetermined confidence range is a probability distribution range of a certain percentage under the normal distribution of arm length. For example, for an 8-year-old child, when the confidence range is 80%, the arm length (inside) is 33 cm to 37.5 cm. When the player's arm length falls within this range, in a specific embodiment of the present invention, it can be determined that the game account was established by a child player around 8 years old, and measures to prevent children from becoming addicted to games will be taken for the game account later.

[0054] For some difficult to judge situations, such as teenagers between 12 and 14 years old, whose arm length may be close to that of ordinary adults, or exceed the confidence range of adults, the present invention can also be combined with other methods for comprehensive distinction, such as facial feature recognition, real-name registration and other technical means. However, this is not the main factor considered in the specific implementation of the present invention, because the primary purpose of the specific implementation of the present invention is to prevent children, a group of this characteristic group, from becoming addicted to games. Of course, further improvements on this basis are also allowed.

[0055] In addition, in the method for preventing children from being addicted to games according to a specific embodiment of the present invention, the player individual identification information includes the player's thumb fingerprint information; during the game account establishment process, the player is prompted to press the fingerprint identification area of ​​the smart terminal with his thumb to obtain the player's thumb fingerprint information, and the player's thumb fingerprint information is associated with the game account information, that is, the game account information is associated with a pre-stored thumb fingerprint information; thereafter, during the use of the game account, the game account information is matched according to the player individual identification information according to the game account use start-up and game account use implementation stages, including:

[0056] In the game account use start-up phase, the game account use is started using the player's thumb fingerprint information. If the player's thumb fingerprint information cannot match the stored player's thumb fingerprint information associated with the game account information, the game account use is not started;

[0057] During the implementation phase of game account use, the fingerprint recognition area of ​​the smart terminal is set as the commonly used game button area, and the player's thumb fingerprint information is collected in this commonly used game button area at a predetermined time interval to match the game account information; if the player's thumb fingerprint information cannot match the stored player's thumb fingerprint information associated with the game account information, the game account will be exited.

[0058] The specific implementation of the present invention is not to simply determine whether the player corresponding to the game account is an adult player or a child player, but to effectively prevent the situation where a child player uses an adult account to log in and play the game. Therefore, in the specific implementation of the present invention, the game account information is matched according to the player's individual identification information according to the stages of starting the game account use and implementing the game account use, and the game account start or exit is restricted according to the matching result.

[0059] For example, the fingerprint recognition area of ​​the smart terminal is set as a commonly used game button area, such as an attack button area or a moving direction button area in an action game, or a button area for releasing commonly used skills, etc. When the game player is playing a normal game, it is difficult to bypass pressing the fingerprint recognition area, otherwise the game will be difficult to proceed normally. Then, according to the predetermined time interval, the smart terminal collects the player's thumb fingerprint information through the fingerprint recognition area of ​​the smart terminal according to the method of the present invention, for example, once every 5 minutes, and matches it with the account information after collection. Because in the account establishment stage, the account information has been associated with the saved player's thumb fingerprint information, so the collected thumb fingerprint information is matched with the game account information. In fact, the player's thumb fingerprint information collected according to the predetermined period during the game is compared with the pre-stored player's thumb fingerprint information collected in the account establishment stage and associated with the game account information. When the comparison result is that it cannot match, the smart terminal determines that the current game player is not the registrant of the game account, so it forcibly takes measures to exit the use of the game account. Therefore, the present invention can effectively prevent children from using adult accounts to log in to the game, or children continue to play the game after adults log in, effectively eliminating the way for children to indulge in games.

[0060] In addition, in the method for preventing children from becoming addicted to games of the present invention, the anti-addiction measures for games include limiting the time period for using a game account, limiting the duration for using a game account, limiting the level range of a game account, limiting the attribute range of a game account, limiting the functional range of a game account, limiting the payment function or payment amount of a game account, or one or more of the above.

[0061] In order to prevent children from being addicted to games, the methods adopted in the present invention are to reduce game viscosity or increase difficulty, avoid consumption, limit duration or time period, etc. These methods can be implemented by calling the control program inside the game.

[0062] In addition, in the method for preventing children from becoming addicted to games according to a specific embodiment of the present invention, obtaining the player's arm length information includes the following steps:

[0063] A01. Prompt the player's avatar area on the screen of the smart terminal, and prompt the player to straighten his forearm to establish a game account on the screen; turn on the front camera of the smart terminal, and when the front camera captures the player's facial image in the prompt player avatar area, identify and record the feature position in the player's avatar area, and use the height sensor and angle sensor in the smart terminal to record the pitch angle and height of the smart terminal;

[0064] A02, repeatedly executing step A01 for multiple times, changing the horizontal position of the player avatar area on the smart terminal screen relative to the previous execution of step A01; in the multiple executions of step A01, each time recording the characteristic position in the player avatar area, the pitch angle and the height of the smart terminal;

[0065] A03. Calculate the player's arm length information by using the characteristic positions in the player's head portrait area recorded multiple times, the pitch angle and height of the smart terminal.

[0066] One of the core elements of the specific implementation of the present invention is to distinguish whether the game account corresponds to a child player or an adult player through the player's physical characteristics, especially the player's arm length information. Accurately obtaining the player's arm length information is one of the key factors in achieving the technical effect of the present invention.

[0067] Figures 2 (a) to 2 (c) are schematic diagrams of a smart terminal interface for a method for preventing children from getting addicted to games according to a specific embodiment of the present invention. Figures 3 (a) to 3 (c) are schematic diagrams of the arm length information measurement principle for a method for preventing children from getting addicted to games according to a specific embodiment of the present invention. The following is a detailed explanation of the method for estimating the player's arm length in a specific embodiment of the present invention in conjunction with Figures 2 (a) to 2 (c) and Figures 3 (a) to 3 (c).

[0068] Assuming that the front camera of the smart terminal is located at the top, as shown in Figure 3 (a), when the player's game account is established, if the player stretches his arm and places the smart terminal directly in front of the player, and assuming that the target point is the midpoint of the line connecting the player's eyes and is located directly in front of the front camera, then according to the imaging principle of the camera, if the camera angle or focal length compensation is not performed, the player's face will appear in the center area of ​​the screen; the position of the target point on the screen is called the characteristic position of the player's avatar area, or simply the characteristic position; at this time, the player's arm length L is an unknown quantity.

[0069] Assuming that the horizontal position of the smart terminal moves downward, for example, a vertical displacement d is generated, the angle of the target point relative to the front camera changes, that is, the angle θ of the line connecting the target point and the front camera and the vertical line of the smart terminal changes, and the player's face will appear in the upper area of ​​the screen, where θ=arttan(d / L). At this time, the shooting angle of the target point for the front camera is θ.

[0070] Assume that the horizontal position of the smart terminal does not change, but its pitch angle changes, that is, as shown in Figure 3 (b), the smart terminal tilts forward at an angle θ relative to the vertical position. At this time, the player's face will appear in the upper area of ​​the screen, and the same result is obtained by moving the vertical displacement d mentioned above. The shooting angle of the target point to the front camera is angle θ. For the mobile terminal, although L is an unknown quantity, since the vertical displacement d and the pitch angle θ can be measured by the height sensor or barometer and gyroscope in the smart terminal, the player's arm length L can be calculated through the same relationship as the above shooting angle.

[0071] Assume that the situation is a little more complicated. The smart terminal includes changes in both the pitch angle and the horizontal position, as shown in Figure 3 (c). This is equivalent to the superposition of two shooting angles. The principle is similar to the above. The player's arm length L can also be calculated through the same relationship between the two shooting angles.

[0072] In addition, if two identical target point imaging positions, i.e., characteristic positions, are not set, according to the corresponding relationship between the target point imaging position and the shooting angle of the smart terminal, in the specific implementation of the present invention, two different target point imaging positions may be set so that the shooting angles corresponding to the two target point imaging positions satisfy a certain proportional relationship, for example, θ 1 =arttan(d / L)=θ 2 / 2; Since the relationship between the imaging position on the screen and the shooting angle can be easily determined in advance in the imaging algorithm of the smart terminal, different target point imaging positions can be set, and the player's arm length L can still be calculated by using the predicted correspondence between the imaging position on the screen and the shooting angle.

[0073] In the above implementation, FIG3 (a) and FIG3 (b) use different methods to make the imaging position of the target point the same and achieve the same shooting angle. Therefore, the simplest implementation method for calculating the player's arm length information in the present invention is to keep the imaging position of the target point the same, that is, the player's head area is the same; in this case, the player is required to move the horizontal height of the smart terminal and change the pitch angle of the smart terminal, thereby calculating the player's arm length information. However, it is found through experiments that due to people's usage habits, if the player is required to keep the imaging position of the target point the same, the player tends to use the same horizontal height and pitch angle of the smart terminal. In this way, it is meaningless to compare the two times, and it is difficult to achieve the purpose of the present invention.

[0074] Therefore, in the specific implementation of the present invention, another solution is adopted - during the execution of step A01 multiple times, each time relative to the last execution of step A01, the player's head portrait area is adjusted to a different horizontal position on the smart terminal screen, that is, the imaging position of the target point is adjusted to a different horizontal height, and then the player's arm length L is calculated based on the corresponding relationship between the imaging position of the target point and the shooting angle. Although this solution requires the use of the corresponding relationship between the imaging position on the screen and the shooting angle, it is more feasible and has a higher calculation accuracy.

[0075] Of course, in the specific implementation manner of the present invention, it is only required to repeat step A01 for multiple times. Each time step A01 is executed, the player avatar area is changed to a different horizontal position on the smart terminal screen relative to the previous execution of step A01. There is no requirement that the player avatar area is at a different horizontal position each time step A01 is executed. In fact, for example, when step A01 is executed for the first and third time, the player avatar area at the same horizontal position can be used as a prompt.

[0076] The above calculation includes some assumptions, such as the front camera of the smart terminal is located in the middle, and the camera imaging angle compensation is not considered, which will cause other interferences in the player's arm length calculation. However, these interferences will not change due to changes in the horizontal height and pitch angle of the smart terminal. Therefore, it is only necessary to increase the number of executions of step A01 to remove these interferences in the horizontal heights and pitch angles of different smart terminals.

[0077] Taking Figure 2 (a) to Figure 2 (c) as an example, the smart terminal first displays a circle in the upper middle of the top of the screen as a prompt for the player's avatar area, requiring the player to adjust the smart terminal so that the player's facial image area is located within this circle. At this time, the image recognition technology can be used to find the midpoint of the binocular line in the player's avatar, that is, the feature position in the player's avatar area, and record the coordinate Y of this feature position on the screen. 1 . And record the horizontal height value Z of the smart terminal in the three-dimensional space at this time 1 and pitch angle information θ 1 .

[0078] Next, the smart terminal displays a circle at the top center of the screen as a prompt, asking the player to adjust the smart terminal so that the player's head area is within this circle. At this time, the image recognition technology can be used to find the midpoint of the binocular line in the player's head, that is, the characteristic position in the player's head area, and record the coordinate Y of this characteristic position on the screen. 2 . And record the horizontal height value Z of the smart terminal in the three-dimensional space at this time 2 and pitch angle information θ 2 .

[0079] Next, the smart terminal displays a circle at the top middle and bottom of the screen as a prompt, asking the player to adjust the smart terminal so that the player's head area is within the circle. At this time, the image recognition technology can be used to find the midpoint of the binocular line in the player's head, that is, the characteristic position in the player's head area, and record the coordinate Y of this characteristic position on the screen. 3 . And record the horizontal height value Z of the smart terminal in the three-dimensional space at this time 3 and pitch angle information θ 3 .

[0080] Assume that in the above process, Y 2 The center horizontal height of the screen, and Y 2 -Y 1 = Y 3 -Y 2 , then the result of executing step A01 three times satisfies the constraint condition: arctan(D 2 / L)+(θ 3 -θ 2 ) = arctan(D 1 / L)+(θ 2 -θ 1 ); where D2 = Z 3 -Z 2 ; and D1 = Z 2 -Z 1 . Based on this constraint, the player’s arm length information L can be calculated.

[0081] The simplest calculation method is adopted in the above implementation. In fact, in the process of executing step A01 each time, the distance between the target point imaging positions may not be equal, and no target imaging point may be the center position. However, these problems can be solved by increasing the number of times step A01 is executed by taking the difference between the horizontal height and the pitch angle each time.

[0082] In the screen prompt information of Figures 2 (a) to 2 (c), the player can also be prompted to stretch his arm as far as possible to obtain accurate arm length information. If the player does not follow this requirement, for example, the calculated arm length is shortened, causing the smart terminal to mistakenly identify the adult player as a child player, but this does not prevent the use of the method of preventing children from indulging in games of the present invention, so that real children can be accurately identified every time, because real children have no way to extend the smart terminal farther under the premise of using their thumb to press when the game account is established, so that the smart terminal can obtain longer arm length information, which further causes their account information to be misjudged as belonging to an adult player. Assuming that the child uses a device such as a selfie stick to extend the "arm length", the fingerprint recognition module cannot obtain the fingerprint information at this time, and the specific implementation of the present invention will not use the front camera to capture the player's facial image, and will not judge the "extended arm length information". Assuming that a child wants to use someone else's thumb to press the fingerprint recognition area of ​​the smart terminal, although a longer arm length information can be obtained, the recorded thumb fingerprint information belongs to someone else. When the child uses the game account to run the game, he will not be able to log in, or even if he logs in, the account will be suspended for a short time. Therefore, the present invention can truly prevent children from becoming addicted to games and making it difficult to avoid restrictive measures by interweaving the acquisition of player individual identification information (thumb fingerprint information) and player physical feature information (arm length information), and bundling the player individual identification information with the execution of the game account use function.

[0083] In addition, as an auxiliary solution, in order to avoid the situation where the player's arms are not straightened when performing facial image recognition, resulting in the arm length information being "shortened", in addition to the prompt "Please stretch your arms as straight as possible" on the screen, the player's avatar area on the screen can also be reduced, that is, the facial image circle in Figure 2, to force the player to stretch the smart terminal further as much as possible.

[0084] Therefore, in the method for preventing children from getting addicted to games according to the specific embodiment of the present invention, during each execution of step A01, the player is prompted to press the fingerprint recognition area on the fingerprint recognition area of ​​the screen of the smart terminal with his thumb, as shown in Figures 2 (a) to 2 (c). The fingerprint recognition and recording functions are used as a prerequisite for capturing and identifying the player's facial image using the front camera, and the thumb is required to keep pressing on the fingerprint recognition area to execute steps A01 and A02. In other words, the process of forcing the acquisition of the player's individual identification information and the acquisition of the player's physical feature information are intertwined.

[0085] In a specific implementation manner of the present invention, the fingerprint recording function of the fingerprint recognition area of ​​the intelligent terminal is used to start the fingerprint registration function during each execution of step A01 to record partial fingerprint information of the player's thumb; after executing step A01 multiple times to record partial fingerprint information of the player's thumb, the partial fingerprint information of the player's thumb recorded multiple times is spliced ​​in step A03, and if the splicing result reaches the completeness standard of fingerprint registration, the thumb fingerprint information of the splicing result is recorded as the player's individual identification information; otherwise, the player is prompted to press the fingerprint recognition area with his thumb again, and the fingerprint registration function is continued to be started to record partial fingerprint information of the player's thumb and add it to the splicing until the splicing result reaches the completeness standard of fingerprint registration.

[0086] In a specific implementation of the present invention, in addition to the player's physical feature information - arm length information, another important information is the player's individual identification information - in particular, the player's thumb fingerprint information, because according to statistics, the player's thumb is the finger most commonly used in the game process. In the prior art, the under-screen fingerprint entry technology of the smart terminal generally adopts a process of multiple partial entry, collection, superposition and integration. When the integrity of the integrated fingerprint information meets the predetermined requirements, the fingerprint information entry is declared successful. Therefore, the present invention also adopts a similar method - in step A03, the partial fingerprint information of the player's thumb recorded multiple times is spliced. If the splicing result reaches the integrity standard of fingerprint registration, the thumb fingerprint information of the splicing result is recorded as the player's individual identification information; otherwise, the player is prompted to press the fingerprint identification area with his thumb again, and the fingerprint registration function is continued to be enabled, and the partial fingerprint information of the player's thumb is recorded and added to the splicing until the splicing result reaches the integrity standard of fingerprint registration. The specific diagram is shown as an example in Figure 2 (a) to Figure 2 (c).

[0087] It should be noted that the acquisition of the player's individual identification information of the present invention is carried out under the premise of obtaining the player's consent during the account establishment process, and the player's individual identification information cannot be used for other purposes.

[0088] In particular, in the method for preventing children from becoming addicted to games according to a specific embodiment of the present invention, when the front camera captures a player avatar located in an area prompting the player avatar, identifying and recording the characteristic position of the player avatar area includes taking the midpoint of the binocular line in the player's facial image in the player avatar area as the characteristic position, and recording the coordinate value of the characteristic position.

[0089] According to the above description, the midpoint of the binocular connection line of the player's face is the target point. When the front camera captures the player's facial image in the area that prompts the player's avatar, the imaging position of the target point on the screen is the characteristic position of the player's avatar area, which can make the calculation of the shooting angle more accurate.

[0090] In particular, in the method for preventing children from playing games according to a specific embodiment of the present invention, in step A01, when the front camera captures the player's facial image in the area prompting the player's avatar, the horizontal distance of the symmetrical position of the player's torso relative to the characteristic position is identified. When the ratio of the horizontal distance of the symmetrical position of the player's torso relative to the characteristic position exceeds a predetermined threshold range, it is determined that the smart terminal is not located directly in front of the player, and the player is prompted by the smart terminal to place the smart terminal directly in front of the player to recapture the player's facial image; when the ratio of the horizontal distance of the symmetrical position of the player's torso relative to the characteristic position is within a predetermined threshold range, it is determined that the smart terminal is located directly in front of the player, and other operations of step A01 are continued to be executed; and in step A02, for some or all of the executions of step A01, the horizontal distance of the symmetrical position of the player's torso relative to the characteristic position is identified, and a judgment is made as to whether the smart terminal is located directly in front of the player. According to the judgment result, the player is prompted by the smart terminal to place the smart terminal directly in front of the player to recapture the player's facial image.

[0091] Another factor to consider is that when the player changes his posture, for example, when the body is facing sideways to the smart terminal and the neck is twisted to capture the player's head portrait and identify the player with the front camera, there is a large distance difference from the body facing the smart terminal to capture the player's head portrait and identify the player with the front camera, which may cause the smart terminal to misjudge the player's type. There may be child players who want to take advantage of this distance difference to deceive the smart terminal and establish a game account corresponding to the adult category. To avoid the occurrence of this loophole, the present invention also includes in step A01, and in part or all of step A01 in step A02 (depending on whether the symmetrical position of the body trunk can be captured and identified by the front camera); when the front camera captures the player's facial image in the area prompting the player's head portrait, identify the horizontal distance of the symmetrical position of the player's body trunk relative to the feature position, the symmetrical position of the body trunk, such as the imaging position of the outer side of the shoulders on the screen. If the body is turned sideways toward the smart terminal and the neck is twisted so that the front camera can capture and identify the player's facial image, the horizontal distance between the imaging position of the outer sides of the shoulders on the screen and the characteristic position may be greatly different, or even one shoulder may not be captured; when the player's body is turned toward the smart terminal so that the front camera can capture and identify the player's portrait, the horizontal distance between the imaging position of the outer sides of the shoulders on the screen and the characteristic position may be basically consistent.

[0092] When the smart terminal determines to execute step A01, if the player's body is facing the front camera of the smart terminal, step A01 can be executed normally. Otherwise, the player is prompted on the screen to adjust the posture to face the front camera of the smart terminal, and then the front camera is used to capture the image of the player's head portrait and torso to determine whether the player's body is facing the front camera of the smart terminal.

[0093] Corresponding to the method for preventing children from being addicted to games in the specific embodiment of the present invention, the specific embodiment of the present invention also provides a smart terminal for preventing children from being addicted to games, wherein the smart terminal can use a game account to execute a game function, and the smart terminal includes a game account establishment module and a game account use module, wherein the account establishment module includes an account information unit, a player individual identification information acquisition unit, a player physical feature information acquisition unit and a player differentiation unit; wherein,

[0094] The player individual identification information acquisition unit is used to acquire the player individual identification information; the player physical characteristic information acquisition unit is used to acquire the player physical characteristic information; the account information unit is used to establish or record the game account information; the player distinguishing unit is used to distinguish whether the game account corresponds to a child player or an adult player using the player physical characteristic information; the game account establishing module associates the game account information with the player individual identification information and the player physical characteristic information;

[0095] The game account usage module is used to match game account information according to the player's individual identification information during the use of game accounts on smart terminals, and to take game addiction prevention measures for game accounts belonging to child players based on the player differentiation results of the game accounts.

[0096] In particular, in the smart terminal for preventing children from indulging in games according to the specific implementation of the present invention, the player individual identification information acquisition unit includes a fingerprint recognition module of the smart terminal, and the player individual identification information includes the player's thumb fingerprint information; the game account establishment module is used to prompt the player to press the fingerprint recognition area of ​​the smart terminal with his thumb to obtain the player's thumb fingerprint information; the game account use module is used to match the game account information according to the player individual identification information according to the game account use start-up and game account use implementation stages during the game account use process;

[0097] The player's body feature information acquisition unit includes a front camera of the smart terminal, a height sensor and an angle sensor in the smart terminal; the player's body feature information acquisition unit is used to prompt the player's avatar area at different horizontal positions on the screen of the smart terminal for multiple times, and prompt the player to straighten his forearm to establish a game account on the screen, turn on the front camera of the smart terminal, and when the front camera captures the player's facial image in the prompt player avatar area, identify and record the feature position in the player's avatar area, and use the height sensor and angle sensor in the smart terminal to record the pitch angle and height of the smart terminal; the player's body feature information acquisition unit is also used to use the feature positions in the player's avatar area recorded multiple times, the pitch angle and height of the smart terminal, to infer the player's arm length information as the player's body feature information.

[0098] The beneficial technical effects of the present invention include the following.

[0099] (1) By using the hardware functions of common smart terminals to obtain the player's individual identification information and physical characteristics information, a method for preventing children from becoming addicted to games is implemented. There is no need to upgrade the hardware structure of the smart terminal itself, so the method has a wide range of applications and is easy to put into practical use.

[0100] (2) Through the camera function and the sensor function of the smart terminal, the player's head portrait or the specific position of the player's face on the smart terminal screen is cleverly used, and the corresponding relationship between the horizontal height and pitch angle of the smart terminal is used to determine the player's arm length information using geometric calculation methods. This is used to distinguish whether the game account corresponds to an adult player or a child player. Compared with methods such as facial feature recognition to distinguish between adult players and child players, this method has higher credibility and is more accurate.

[0101] (3) The present invention obtains the player's individual identification information when collecting the player's physical feature information. That is, the player's thumb is required to be kept pressed in the fingerprint recognition area of ​​the smart terminal before the front camera of the smart terminal is used to recognize the player's facial image to determine the player's arm length. This can effectively prevent children from deceiving the smart terminal, for example, by using a selfie stick or with the help of others to enable the smart terminal to obtain "false" arm length information.

[0102] (4) During the use of a game account, the game account information shall be matched according to the player’s individual identification information, in accordance with the stages of starting the game account use and implementing the game account use. This can prevent children from impersonating an adult’s account to start or run the game, and ensure that the function of preventing children from becoming addicted to games is truly implemented.

[0103] (5) In order to improve the accuracy of player identification, the player's front body and facial graphics can be accurately captured by identifying the position of the smart terminal in front of the player, thereby improving the calculation accuracy of the player's arm length information.

[0104] (6) The method of preventing children from becoming addicted to games of the present invention can be implemented as an independent function as a bottom-level function of a smart terminal, or can be embedded as a part of a game. It has a high degree of autonomy and is easy to implement.

[0105] (7) The method and intelligent terminal for preventing children from becoming addicted to games of the present invention can truly prevent children from becoming addicted to games, thereby ensuring the physical and mental health and academic progress of children, and having a good social influence and positive social effect.
