Description

Method, system, and recording medium for providing AI-based personalized digital content

[0001] The present invention relates to a method, system, and recording medium for providing digital content, and more particularly, to a method, system, and recording medium for providing user-customized digital content based on artificial intelligence.

[0002] Digital content is content that exists in digital data format, and is the digitization of existing analog content. It is content such as text, voice, sound, image, and video that is produced or processed in digital format.

[0003] The digital content industry is experiencing rapid growth in demand driven by rapid advancements in hardware and networks, and is being utilized in a wide range of fields, including games, animation, mobile content, digital video, e-learning, e-books, digital audio, and, more recently, digital therapeutics.

[0004] Patients with developmental delays are known to exhibit a wide range of cognitive impairments. Timely assessment of a patient's cognitive status and current state, and appropriate cognitive enhancement accordingly, are crucial for children in early childhood, as they provide the foundation for cognitive, emotional, and social growth, which is central to communication and subsequent language development.

[0005] In the past, in order to identify the cognitive deficiencies of patients with developmental delay, understand their current status, and improve those abilities, the patient's cognitive deficiencies were identified through several questionnaires or the judgment of therapists / doctors, and training and treatment by professional educators using books or learning materials were continuously repeated to provide training in tasks related to that area.

[0006] However, conventional methods inevitably faced constraints of time and space, and the effectiveness of professional training varied significantly depending on the individual qualities and abilities of the patient undergoing the training. Furthermore, they faced limitations in properly tracking and managing the effects of training and treatment, as well as the progress of cognitive improvement.

[0007] To overcome these limitations, digital therapeutics can partially replace in-person treatment, offering the advantage of non-face-to-face treatment without time, location, or frequency restrictions.

[0008] However, existing digital therapeutics have the problem of not reflecting the individual qualities or abilities of users by applying the same treatment subject performance order, performance ratio, and performance steps to all users.

[0009] Regarding a digital treatment method for patients with developmental delay, No. 10-2022-0051626 proposes a method for sequentially providing cognitive ability enhancement learning content stored in a content DB from lower to higher levels for cognitive ability enhancement learning.

[0010] However, for patients with developmental delay who are known to show a wide range of cognitive impairments, the method of applying the same performance order, performance ratio, and performance steps of treatment subjects to all has limitations in focusing on training the patient's deficient abilities, and there was a problem of poor content performance and low accuracy when continuously applying the same performance order, performance ratio, content activities, and steps despite the patient's current condition affecting the ability to perform treatment subjects.

[0011] The present invention has been devised to solve the above-mentioned conventional problems, and its purpose is to provide a digital content provision method, system and recording medium that pre-evaluate a child's content performance ability through pre-evaluation content and adjust the initial starting level of digital content.

[0012] In addition, the purpose is to provide a digital content providing method, system and recording medium that adjusts the difficulty level, performance order and performance ratio of digital content by using response data obtained while a user performs digital content.

[0013] In addition, the purpose is to provide a method, system, and recording medium for providing personalized digital content based on artificial intelligence by accumulating, storing, and analyzing response data obtained while a user is performing digital content.

[0014] In order to achieve the above object, a method for providing user-customized digital content according to the present invention comprises the steps of: storing, for each digital content, at least one sensory element among visual, auditory, and tactile senses required for performing the digital content; providing digital content belonging to a content group including a plurality of digital contents to the user; collecting response data obtained from at least one of visual, auditory, and tactile senses indicating the user's response while the digital content is provided; evaluating the user's overall immersion using the response data; and changing the content group or changing to another digital content within the same content group according to the overall immersion and providing the same to the user.

[0015] In addition, a system for providing user-customized digital content according to the present invention is characterized by including: a sensory element storage unit that stores, for each digital content, at least one sensory element among visual, auditory, and tactile senses required to perform the digital content; a content provision unit that provides digital content belonging to a content group including a plurality of digital contents to the user; a response data collection unit that collects response data obtained from at least one of visual, auditory, and tactile senses indicating the user's response while the digital content is provided; an evaluation unit that evaluates the user's overall immersion using the response data; and a content change unit that changes the content group according to the overall immersion or changes it to another digital content within the same content group and provides it to the user.

[0016] In addition, a recording medium storing commands for performing the following steps to implement a method for providing user-customized digital content according to the present invention is characterized in that the commands include: a step of storing, for each digital content, at least one sensory element among visual, auditory, and tactile senses required for performing the digital content; a step of providing digital content belonging to a content group including a plurality of digital contents to the user; a step of collecting response data obtained from at least one of visual, auditory, and tactile senses indicating the user's response while the digital content is provided; a step of evaluating the user's overall immersion using the response data; and a step of changing the content group or changing to another digital content within the same content group according to the overall immersion and providing the same to the user.

[0017] As discussed above, by evaluating the user's content performance ability through evaluation content, it provides the effect of adjusting the initial starting level of digital content.

[0018] In addition, the present invention provides the effect of allowing the user to focus on training the user's insufficient abilities by adjusting the difficulty level, performance order, and performance ratio of the digital content using the response data obtained while the user is performing the digital content.

[0019] In addition, the present invention provides the effect of enabling the provision of artificial intelligence-based personalized digital content by accumulating, storing, and analyzing response data obtained while a user is performing digital content.

[0058] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached to this specification.

[0059] Figure 1 is a configuration diagram of a digital content provision system (100) according to one embodiment of the present invention.

[0060] Referring to FIG. 1, a digital content provision system (100) according to one embodiment is composed of a content receiving unit (110), a content providing unit (120), a response data collection unit (130), an evaluation unit (140), a content changing unit (150), and a communication unit (160).

[0061] The content receiving unit (110) receives at least one digital content from the content DB (210) of the server (200) via the communication unit (160). The digital content may be training content for strengthening the user's insufficient abilities, and preferably, may be training content for strengthening the user's insufficient abilities using gamification.

[0062] The above content provision unit (120) provides the digital content in which the sensory element and the target object are stored to the user through any one of visual, tactile, and auditory methods.

[0063] The above reaction data collection unit (130) is composed of a photographing module (131), a voice recognition module (132), and a touch input module (133), and collects reaction data obtained from at least one of visual, auditory, and tactile senses indicating the user's reaction while the content providing unit (120) provides the digital content to the user.

[0064] When the above reaction data includes visual data, at least one of whether the user looks at the display, whether the user blinks, whether the user looks at the target object, the time taken to look at the target object, and the time spent looking at the target object can be collected using the shooting module (131).

[0065] The above-mentioned shooting module (131) may preferably be a camera, but is not limited thereto.

[0066] If the above response data includes auditory data, at least one of whether the user spoke, the voice, the time when the speech started, and the speech time can be collected using the voice recognition module (132).

[0068] When the above reaction data includes tactile data, at least one of whether the user touches the target object, the time taken to touch the target object, and the time spent touching the target object can be collected using the touch input module (133).

[0069] The above touch input module (133) may be a display equipped with a touch function, but is not limited thereto.

[0070] The evaluation unit (140) uses the collected response data to evaluate the user's overall immersion. A detailed description of the method for evaluating the overall immersion will be provided below.

[0071] The above content change unit (150) changes the content group to improve the user's immersion according to the overall immersion, or changes it to other digital content within the same content group and provides it to the user.

[0072] The above content group may consist of multiple digital contents to enhance user immersion. For example, the content group may be language expression training, and the digital contents may be training contents using similar words and sentences.

[0073] The above communication unit (160) can communicate with the terminal (300) or the server (200) via a network.

[0074] The terminal (300) described in this specification may include a mobile phone, a smart phone, a laptop computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation device, a slate PC, a tablet PC, an ultrabook, a wearable device (e.g., a smartwatch, a smart glass, an HMD (head mounted display), etc.).

[0075] Referring to FIG. 1, the server (200) is composed of a content DB (210), a sensory element storage unit (220), a target object storage unit (230), a reaction data storage unit (240), and an artificial intelligence processing unit (250).

[0076] The above content DB (210) stores a plurality of digital contents and transmits the digital contents to the content receiving unit (110) at the request of the content receiving unit (110).

[0077] In addition, the content DB (210) includes a plurality of content groups, and each content group is composed of a plurality of digital contents.

[0078] The above sensory element storage unit (220) stores at least one sensory element among visual, auditory, and tactile senses required for a user to perform the digital content for each digital content.

[0079] The target object storage unit (230) stores, for each digital content, location information about a target object (400) on which at least one of the user's visual and tactile senses must be focused within the display of the terminal (300) on which the digital content is executed.

[0080] The above reaction data storage unit (240) receives, accumulates, and stores the user's reaction data collected by the reaction data collection unit (130).

[0081] The above artificial intelligence processing unit (250) can provide customized digital content to the user by using artificial intelligence to change the content group or the digital content based on the user's digital content performance history and the overall immersion evaluation results.

[0082] FIG. 2 is a flowchart illustrating a method for providing digital content according to one embodiment of the present invention, FIG. 3 is a diagram illustrating a method for storing a sensory element in digital content according to one embodiment of the present invention, FIG. 4 is a diagram illustrating a method for storing a sensory element in digital content according to another embodiment of the present invention, and FIG. 5 is a diagram illustrating a method for storing a sensory element in digital content according to still another embodiment of the present invention.

[0083] Referring to FIG. 2, the method for providing digital content includes a step (S100) of storing at least one sensory element among visual, auditory, and tactile senses required for performing digital content for each digital content, a step (S200) of providing digital content belonging to a content group including a plurality of digital contents to the user, a step (S300) of collecting reaction data obtained from at least one of visual, auditory, and tactile senses indicating the user's reaction while the digital content is provided, a step (S400) of evaluating the user's overall immersion using the reaction data, and a step (S500) of changing the content group or changing to another digital content within the same content group according to the overall immersion and providing the same to the user.

[0084] Below, each step is explained in detail.

[0085] The step (S100) of storing at least one sensory element among visual, auditory, and tactile senses required to perform the above digital content for each digital content is a step in which the sensory element storage unit (220) stores the sensory element in the digital content stored in the content DB (210). The storage process may be automatically stored by a program included in the sensory element storage unit (220), or may be manually stored by a system administrator.

[0086] As an example, referring to FIG. 3, multiple digital contents (Content 1, Content 2, and Content 3) for joint attention training are provided, and the sensory elements required to perform each digital content can be stored in each digital content. Specifically, Content 1 may store visual information, Content 2 may store auditory information, and Content 3 may store tactile information.

[0087] As another example, referring to FIG. 4, the step (S100) of storing at least one sensory element among visual, auditory, and tactile senses required to perform the digital content for each digital content may set the sensory element ratios occupied by visual, auditory, and tactile senses among the sensory elements included in the digital content, and the sensory element storage unit (220) may store the sensory element ratios for each digital content. Specifically, a plurality of digital contents (contents 4, 5, and 6) for language attention training may be provided, and the sensory element ratios occupied by the sensory elements required to perform each digital content may be stored in each digital content. Specifically, content 4 may store 50% visual, 50% tactile, and 0% auditory senses, content 5 may store 50% visual, 0% tactile, and 50% auditory senses, and content 6 may store 40% visual, 30% tactile, and 30% auditory senses. At this time, the overall immersion can be evaluated by applying the sensory element ratio of the digital content as a weight.

[0088] These sensory element ratios can also be extracted using artificial intelligence.

[0089] As another example, referring to FIG. 5, the step (S100) of storing at least one sensory element among visual, auditory, and tactile senses required to perform the digital content for each digital content may set the sensory element ratios occupied by visual, auditory, and tactile senses among the sensory elements included in the digital content, and the sensory element storage unit (220) may store the sensory element ratios in the digital content at regular time intervals. Specifically, a plurality of digital contents (contents 7 and 8) for language expression training may be provided, and the sensory element ratios occupied by the sensory elements required to perform each digital content may be stored in each digital content at regular time intervals. Specifically, in the content 7, 100% of the visual, 0% of the tactile, and 0% of the auditory senses may be stored in the first section, and 50% of the visual, 0% of the tactile, and 50% of the auditory sense may be stored in the second section. The above content 8 may store 40% of visual, 30% of tactile, and 30% of auditory information in the first section, and 40% of visual, 60% of tactile, and 0% of auditory information in the second section. In this case, the overall immersion may be evaluated by applying the sensory element ratio of the digital content as a weight.

[0090] In addition, the sensory element storage unit (220) can divide the digital content into a plurality of sections, and store the sensory element ratio differently in the first section and the second section among the plurality of sections.

[0091] Additionally, the length of the first section may be different from the length of the second section.

[0092] FIG. 6 is a diagram showing a method for storing a target object in digital content according to one embodiment of the present invention, FIG. 7 is a flowchart showing a method for evaluating overall immersion according to one embodiment of the present invention, FIG. 8 is a flowchart showing a method for evaluating overall immersion according to another embodiment of the present invention, and FIG. 9 is a flowchart showing a method for evaluating overall immersion according to still another embodiment of the present invention.

[0093] Referring to FIG. 6, the step (S100) of storing at least one sensory element among visual, auditory, and tactile required to perform the digital content for each digital content further includes the step of storing location information for the target object (400) for each digital content.

[0094] The above target object is an object on which at least one of the user's visual and tactile senses must be focused within the display of the terminal (300) on which the digital content is executed.

[0095] As an example, the target object (400) may be an apple hanging from a tree. Specifically, the display may simultaneously display apples in a basket and apples hanging from a tree, and location information of the apples hanging from the tree within the display may be stored in the digital content.

[0096] The step (S200) of providing the above digital content to the user is a step in which the digital content provision system (100) provides at least one digital content to the user through the terminal (300).

[0097] The step (S300) of collecting reaction data obtained from at least one of visual, auditory, and tactile senses indicating the user's reaction while the digital content is provided is a step in which the reaction data collection unit (130) collects the user's reaction.

[0098] As an example, when the sensory element storage unit (220) stores the sensory element ratio in the digital content at regular time intervals, the reaction data collection unit (130) can collect the user's reaction data at regular time intervals.

[0099] As another example, if the reaction data includes visual data, at least one of whether the user looks at the display, whether the user blinks, whether the user looks at the target object, the time taken to look at the target object, and the time spent looking at the target object can be collected using the shooting module (131).

[0100] The above-mentioned shooting module (131) may preferably be a camera, but is not limited thereto.

[0101] As another example, if the above response data includes auditory data, at least one of whether the user spoke, the voice, the time when the speech started, and the speech time can be collected using the voice recognition module (132).

[0102] The above voice recognition module (132) may preferably be a microphone, but is not limited thereto.

[0103] As another example, if the above-mentioned response data includes tactile data, at least one of whether the user touched the target object, the time taken to touch the target object, and the time spent touching the target object can be collected using the touch input module (133).

[0104] The above touch input module (133) may be a display equipped with a touch function, but is not limited thereto.

[0105] The step (S400) of evaluating the overall immersion of the user using the above reaction data is a step in which the evaluation unit (140) evaluates the overall immersion using the user's reaction data collected by the reaction data collection unit (130).

[0106] The above overall immersion is calculated by the reaction data collection unit (130) collecting the reaction data at regular time intervals, and the evaluation unit (140) evaluating the real-time immersion at least once at a set time interval using the reaction data. Preferably, the above overall immersion may be an average value of the real-time immersion.

[0107] The method for evaluating the real-time immersion may include, as an example, referring to FIG. 7, if the digital content includes the visual data, a step of determining a gaze position (S411), a step of determining whether an eye blinks (S412), and a step of determining whether a target object is being gazed at (S413).

[0108] In addition, the step (S411) of determining the gaze position may analyze the user's gaze using the photographing module (131) and determine whether the gaze is positioned on the display of the terminal (300) for a first period of time. Specifically, if it is determined that the gaze is not positioned on the display for the first period of time, the real-time immersion may be set to 'low'. Preferably, the first period of time may be 20 seconds.

[0109] Thereafter, if it is determined that the gaze is positioned on the display for a first period of time, the user's blinking can be determined using the photographing module (131) (S412). Specifically, if it is determined that the user's blinking does not occur for a second period of time, the real-time immersion can be evaluated as 'low'. Preferably, the second period of time can be 60 seconds.

[0110] Thereafter, if it is determined that there is eye blinking, it is possible to determine whether the user's gaze is located within a first radius of the target object of the display using the photographing module (131) (S413). Specifically, if it is determined that the gaze is not located within the first radius of the target object, the real-time immersion can be evaluated as 'medium'. Preferably, the first radius may be 180PX centered on the target object (400).

[0111] Thereafter, if it is determined that the gaze is located within the first radius of the target object (400), the real-time immersion can be evaluated as 'upper'.

[0112] Preferably, the first radius may be 180PX centered on the target object (400).

[0113] As another example, referring to FIG. 8, if the digital content includes the visual data and the auditory data, the method may include a step of determining whether the voice is collected correctly (S421), a step of determining the gaze position (S422), a step of determining whether the eye blinks (S423), and a step of determining whether the user is looking at the target object (S424). Preferably, the step of determining whether the voice is collected correctly may be performed by using a voice recognition algorithm trained with the user's speech data to determine whether the voice collected from the user is included in a preset answer list.

[0114] In addition, the step (S421) of determining whether the voice is collected correctly may analyze the user's voice using the voice recognition module (132) and determine whether the voice is included in a preset answer list. Specifically, if it is determined that the voice is included in the answer list, the real-time immersion may be evaluated as 'high'.

[0115] Thereafter, if it is determined that the voice is not included in the answer list, the user's gaze may be analyzed and it may be determined whether the gaze is positioned on the display of the terminal for a first period of time (S422). Specifically, if it is determined that the gaze is not positioned on the display of the terminal for the first period of time, the real-time immersion may be evaluated as 'low'. Preferably, the first period of time may be 20 seconds.

[0116] Thereafter, if it is determined that the user's gaze is positioned on the display for a first period of time, the user's eye blinking can be analyzed and whether or not the eye blinking occurred (S423). Specifically, if it is determined that the eye blinking did not occur for a second period of time, the real-time immersion can be evaluated as 'low'. Preferably, the second period of time can be 60 seconds.

[0117] Thereafter, if it is determined that there is eye blinking, it is possible to determine whether the user's gaze is located within a first radius of the target object of the display of the terminal using the photographing module (131) (S424). Specifically, if it is determined that the gaze is not located within the first radius of the target object, the real-time immersion can be evaluated as 'medium'. Preferably, the first radius may be 180PX centered on the target object (400).

[0118] Afterwards, if it is determined that the gaze is located within the first radius of the target object, the real-time immersion can be evaluated as 'high'.

[0119] As another example, referring to FIG. 9, if the digital content includes the visual data and tactile data, the step may include a step of determining a gaze position (S431), a step of determining whether an eye blinks (S432), a step of determining whether a target object is being looked at (S433), and a step of determining whether a target object is being touched (S434).

[0120] In addition, the step (S431) of determining the gaze position may analyze the user's gaze using the photographing module (131) and determine whether the gaze is positioned on the display of the terminal for a first period of time. Specifically, if it is determined that the gaze is not positioned on the display for the first period of time, the real-time immersion may be evaluated as 'low'.

[0121] Thereafter, if it is determined that the gaze is positioned on the display for a first period of time, it is possible to determine whether the user's eyes blink using the photographing module (131) (S432). Specifically, if it is determined that the eye blinks do not occur for a second period of time, the real-time immersion level can be evaluated as 'low'.

[0122] Thereafter, if it is determined that there is eye blinking, the photographing means can be used to determine whether the user's gaze is located within a first radius of the target object on the display of the terminal (S433). Specifically, if it is determined that the gaze is not located within the first radius of the target object, the real-time immersion can be evaluated as 'low'.

[0123] Thereafter, if it is determined that the gaze is located within the first radius of the target object, it can be determined whether the target object has been touched (S434). Specifically, if it is determined that the target object has not been touched, the real-time immersion can be evaluated as 'medium'.

[0124] Afterwards, if it is determined that the target object has been touched, the constant real-time immersion can be evaluated as 'high'.

[0125] In the above-described embodiments, examples of evaluating the real-time immersion as "high," "medium," and "low" were provided, but this is not limited thereto. The real-time immersion may be evaluated as an index.

[0126] As another example, after the step (S400) of evaluating the overall immersion of the user using the above reaction data, the history of the user's performance of the digital content and the results of the overall immersion evaluation may be stored. Specifically, the history of the performance of the digital content and the results of the overall immersion evaluation may be accumulated and stored in the reaction data storage unit (240) of the server (200) using the communication unit (160).

[0127] FIG. 10 is a flowchart illustrating a method for maintaining or changing content according to overall immersion according to one embodiment of the present invention.

[0128] Referring to FIG. 10, the step (S500) of changing the content group according to the overall immersion or changing it to another digital content within the same content group and providing it to the user is a step in which the content change unit (150) performs one of maintaining the digital content (S520), changing the content group to another content group (S530), and changing it to another digital content within the content group (S530).

[0129] For example, if the overall immersion is greater than or equal to the first criterion, the digital content can be maintained, and if it is less than the first criterion, the digital content can be changed to another digital content within the content group and provided to the user.

[0130] As another example, if the overall immersion is greater than or equal to a first criterion, the digital content can be maintained, if it is less than the first criterion and greater than or equal to a second criterion, the digital content can be changed to another digital content within the content group and provided to the user, and if it is less than the second criterion, the content group can be changed to another content group and the digital content within the changed content group can be provided to the user.

[0131] As another example, based on the performance history of the digital content accumulated and stored in the reaction data storage unit (240) and the history of the overall immersion evaluation results, the content group can be changed using artificial intelligence, or the process can be controlled by changing to another digital content within the same content group.

[0132] Figure 11 is a flowchart illustrating a method for adjusting the next difficulty level of digital content according to one embodiment of the present invention.

[0133] Referring to FIG. 11, after the step (S500) of changing the content group according to the overall immersion or changing to another digital content within the same content group and providing it to the user, the overall immersion is re-evaluated (S600), and if the overall immersion satisfies the next stage progression criterion of the digital content being performed (S610), the next execution stage of the digital content can be raised (S620). Thereafter, if the previous stage progression criterion of the digital content is satisfied (S630), the next execution stage of the digital content can be lowered (S640), and if it is not satisfied, the next execution stage of the digital content can be maintained (S650).

[0134] Figure 12 is a flowchart illustrating a method for providing pre-evaluation content according to one embodiment of the present invention.

[0135] Referring to FIG. 12, the method for providing pre-evaluation content may further include a step (S710) of storing, for each pre-evaluation content, at least one sensory element among visual, auditory, and tactile elements required for performing digital content, prior to the step (S100) of storing, for each digital content, the sensory elements required for performing pre-evaluation content; a step (S720) of providing pre-evaluation content to the user; a step (S730) of collecting the user's reaction data while the pre-evaluation content is provided; a step (S740) of evaluating the user's overall immersion using the reaction data, and a step of determining the performance stage of the digital content using the overall immersion.

[0136] As an example, a method for determining the performance stage of digital content is as follows: if the overall immersion evaluated as pre-evaluation content is 'low' (S751), the performance stage of the digital content is determined as 'low' (S752); if the overall immersion is 'medium' (S753), the performance stage of the digital content is determined as 'medium' (S754); and if the overall immersion is 'high', the performance stage of the digital content can be determined as 'high' (S755).

[0137] Thereafter, the step (S200) of providing the user with digital content belonging to a content group having multiple digital contents may provide the user with digital content matching the execution step of the digital content.

[0138] FIG. 13 is a drawing showing a method for providing user-customized digital content according to one embodiment of the present invention.

[0139] FIG. 13 is a flowchart illustrating a method for controlling the execution order and execution ratio of a content group according to a process according to one embodiment of the present invention, and FIG. 14 is a flowchart illustrating a method for controlling the content execution ratio or execution time according to one embodiment of the present invention.

[0140] Referring to Fig. 13, the overall immersion of each content group provided to the user according to the process is evaluated (S810), a content group with a low overall immersion among all content groups is placed at the front of the process (S820), and the overall immersion of each content group can be compared with a reference value to adjust the execution rate or execution time (S830).

[0141] As an example, referring to FIG. 14, comparing the overall immersion of each content group with a reference value to adjust the execution ratio or execution time may include increasing the execution ratio or execution time within the process of the content group if the overall immersion of the content group is less than the first reference value (S831), maintaining the execution ratio or execution time within the process of the content group if it is greater than or equal to the first reference value and less than the second reference value (S833), and decreasing the execution ratio or execution time within the process of the content group if it is greater than or equal to the second reference value (S835). Specifically, adjusting the execution ratio within the process may be adjusting the number of executions of the content group, and adjusting the execution time may be adjusting the execution period of the content group to 2 times, 1.5 times, maintaining, or 0.5 times.

[0142] FIG. 15 (a) is a drawing illustrating a method for providing digital content according to one embodiment of the present invention, and FIG. 15 (b) is a drawing illustrating a method for providing a customized process.

[0143] Referring to FIG. 15 (a) and FIG. 15 (b), a user performs a pre-evaluation, and a digital content provision system (100) assigns an initial execution step (content group A is step 1, content group B is step 2, content group C is step 3, content group D is step 1, and content group E is step 3) based on the pre-evaluation result.

[0144] Thereafter, the user performs digital content A of content group A, and the digital content provision system (100) collects the user's response data to evaluate the overall immersion and maintains or changes the content being performed by the user (any one of digital contents B, C, and D within content group A) based on the overall immersion.

[0145] Afterwards, the premise immersion of the above content group A is evaluated and the difficulty level of the next content group A is changed and saved.

[0146] Thereafter, the user performs the digital content provided according to the process, and the digital content provision system (100) evaluates the overall immersion level for each content group to adjust the content execution order and / or execution rate. At this time, the user's digital content execution history and the overall immersion evaluation results are transmitted to the server (200), and the server (200) utilizes accumulated stored data and artificial intelligence to provide content composition and processes tailored to the characteristics and tendencies of each user.
