Technical Field

[0001] The present invention belongs to the field of intelligent libraries and relates to VR experience interaction technology, in particular to an intelligent library experience interaction system and method based on VR technology. Background Art

[0002] VR technology is a technology that enables users to experience and interact with virtual environments through computer-generated simulated environments. VR technology needs to provide high-resolution, low-latency display devices, accurately track users' head, hand and body movements, powerful graphics rendering technology, and provide users with a natural and intuitive way to interact with the virtual environment. VR smart libraries provide users with immersive library experiences and rich learning resources through virtual environments and interactive technologies.

[0003] Under the current technological background, the use of VR technology has elevated the user's reading and viewing experience from a two-dimensional level to a three-dimensional level. When users experience VR technology, they are easily affected by many factors such as display focus, resolution, viewing distance, and device theme wearing experience, which is not conducive to the user's immersive experience. Therefore, how to customize the smart library based on data analysis to improve the user experience is the current problem;

[0004] To this end, we propose an intelligent library experience interaction system and method based on VR technology. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide an intelligent library experience interaction system and method based on VR technology.

[0006] The technical problems to be solved by the present invention are:

[0007] How to realize customized interactive replacement of smart libraries based on VR technology.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] The intelligent library experience interaction system based on VR technology includes a wear detection module, a data acquisition module, a display adjustment module, a behavior recording module, a behavior analysis module, an execution module, a management terminal, a display and a processor;

[0010] The wearing detection module is used to detect the wearing effect of the wearable device and generate a wearing adjustment signal or a normal wearing signal according to the detection result;

[0011] The data acquisition module is used to obtain the user's eye positioning data and send it to the display adjustment module;

[0012] The display adjustment module is used to generate a focus adjustment signal or an interpupillary distance adjustment signal according to the eye positioning data analysis and send it to the execution module;

[0013] The execution module adjusts the position of the display according to the adjustment signal;

[0014] When using wearable devices, users can enter the virtual library through virtual reality programs to interact with reading;

[0015] The behavior recording module is used to record the user's reading interaction data and send it to the behavior analysis module via the processor;

[0016] The behavior analysis module is used to analyze the user's experience interaction, and the user's reading immersion level obtained by the analysis is uploaded to the management terminal through the processor;

[0017] The management terminal adjusts the book push to the user according to the reading immersion level.

[0018] Further, the eye positioning data includes left pupil distance, right pupil distance, left eye pupil coordinates and right eye pupil coordinates;

[0019] Reading interaction data includes the number of details browsed by the user, the number of content browsed, the total reading time of each book, the number of command inputs, the number of blinks and the number of posture adjustments when the user is reading.

[0020] Furthermore, the detection process of the wear detection module is as follows:

[0021] Obtain the real-time pressure of each pressure detection point of the wearable device and the real-time tension of the headband connection point, and compare the real-time pressure of each pressure detection point with the standard pressure range;

[0022] If the real-time pressure at any pressure detection point belongs to the second standard pressure interval, a wearing adjustment signal is generated;

[0023] If the real-time pressures at each pressure detection point belong to the first standard pressure range, the real-time tensions at each headband connection point are compared with the standard tension range one by one;

[0024] If the real-time tension of any headband connection point does not belong to the standard tension range, a wearing adjustment signal is generated;

[0025] If the real-time tension of each headband connection point belongs to the standard tension range, a normal wearing signal is generated;

[0026] Among them, the values ​​of the first standard pressure interval and the second standard pressure interval are both greater than zero, and the values ​​of the first standard pressure interval are both smaller than the second standard pressure interval.

[0027] Furthermore, the adjustment process of the display adjustment module is specifically as follows:

[0028] Mapping the geometric centers of the left and right display screens in the wearable device to the facial coordinate system to obtain the left screen center coordinates, the right screen center coordinates, and the user's left eye pupil coordinates and right eye pupil coordinates;

[0029] Calculate the left screen offset value and the right screen offset value of the wearable device, and compare the left screen offset value and the right screen offset value of the wearable device with the offset somatosensory threshold;

[0030] If either the left screen offset value or the right screen offset value is greater than the offset somatosensory threshold, a focus adjustment signal is generated;

[0031] If the values ​​of the left screen offset value and the right screen offset value are both less than or equal to the offset somatosensory threshold, proceed to the subsequent steps;

[0032] Obtain the user's left pupil distance and right pupil distance and compare them with the standard pupil distance range;

[0033] If the values ​​of the left pupil distance and the right pupil distance both belong to the standard pupil distance range, no operation is performed;

[0034] If any value of the left pupil distance or the right pupil distance does not belong to the standard pupil distance interval, a pupil distance adjustment signal is generated;

[0035] Among them, the values ​​of the offset somatosensory threshold and the standard pupil distance interval are both greater than zero.

[0036] Furthermore, during the use of the wearable device, the user enters the virtual library through the virtual reality program, and the wearable device displays several book covers. After the user selects a book cover, he can browse the book details page. The book details page contains information such as the book title, author, and book type. When the user is on the book details page, he can choose to exit the book details page or further read the book content.

[0037] Furthermore, the analysis process of the behavior analysis module is as follows:

[0038] Obtain the total reading time, number of command inputs, number of blinks, and number of posture adjustments of each book when the user is reading, and calculate the user's behavioral concentration value;

[0039] Obtain the number of detail views and content views of the user, divide the number of content views by the number of detail views to calculate the user's content reading ratio, and compare the user's content reading ratio with the content reading threshold;

[0040] If the value of the content reading ratio is less than or equal to the first content reading threshold, the effective reading coefficient of the user is determined to be the first effective reading coefficient;

[0041] If the value of the content reading ratio is greater than the first content reading threshold and less than or equal to the second content reading threshold, it is determined that the effective reading coefficient of the user is the second effective reading coefficient;

[0042] If the value of the content reading ratio is greater than the second content reading threshold, the effective reading coefficient of the user is determined to be the third effective reading coefficient;

[0043] Calculate the user's reading immersion value, and compare the user's reading immersion value with the standard immersion interval;

[0044] If the reading immersion value belongs to the first standard immersion interval, the user's reading immersion level is determined to be the first reading immersion level;

[0045] If the reading immersion value belongs to the second standard immersion interval, the user's reading immersion level is determined to be the second reading immersion level;

[0046] If the reading immersion value belongs to the third standard immersion interval, it is determined that the user's reading immersion level is the third reading immersion level.

[0047] Furthermore, the values ​​of the first content reading threshold and the second content reading threshold are both greater than zero, the first content reading threshold is less than the second content reading threshold, the effective reading coefficient reflects the proportion of book content actually read by users, the first effective reading coefficient is less than the second effective reading coefficient, and the second effective reading coefficient is less than the third effective reading coefficient.

[0048] Furthermore, the values ​​of the standard immersion intervals are all greater than zero, the value of the first standard immersion interval is smaller than the value of the second standard immersion interval, the value of the second standard immersion interval is smaller than the value of the third standard immersion interval, the reading concentration level of the first reading immersion level is lower than the reading concentration level of the second reading immersion level, and the reading concentration level of the second reading immersion level is lower than the reading concentration level of the third reading immersion level.

[0049] Furthermore, the adjustment measures of the management terminal specifically include:

[0050] If the user's reading immersion level is the first reading immersion level, the book push frequency is increased;

[0051] If the user's reading immersion level is the second reading immersion level, the book push frequency is maintained;

[0052] If the user's reading immersion level is the first reading immersion level, the book push frequency is lowered.

[0053] Secondly, the smart library experience interaction method based on VR technology is as follows:

[0054] Step S101: After the user finishes wearing the device, the wearing detection module detects the wearing effect of the wearable device, generates a wearing adjustment signal or a normal wearing signal and sends it to the display to prompt the user to adjust the wearing effect;

[0055] Step S102: The data acquisition module acquires the user's eye positioning data and sends it to the display adjustment module. The display adjustment module generates a focus adjustment signal or an interpupillary distance adjustment signal according to the eye positioning data analysis and sends it to the execution module. The execution module adjusts the position of the display according to the focus adjustment signal or the interpupillary distance adjustment signal.

[0056] Step S103, during the use of the wearable device, the user can enter the virtual library through the virtual reality program to perform reading interaction, and at the same time, the behavior recording module records the user's reading interaction data and sends it to the behavior analysis module via the processor;

[0057] Step S104, the behavior analysis module analyzes the user's experience interaction, and obtains the user's reading immersion level through the analysis and uploads it to the management terminal via the processor. The management terminal adjusts the user's book push according to the reading immersion level.

[0058] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0059] 1. The present invention first detects the wearing effect of the wearable device through a wearing detection module, generates a wearing adjustment signal or a normal wearing signal and sends it to the display to prompt the user to adjust the wearing, then uses the data acquisition module to obtain the user's eye positioning data and sends it to the display adjustment module, and then generates a focus adjustment signal or an interpupillary distance adjustment signal according to the eye positioning data analysis through the display adjustment module and sends it to the execution module, and the execution module adjusts the position of the display according to the focus adjustment signal or the interpupillary distance adjustment signal;

[0060] 2. During the use of the wearable device, the recording module is also used to record the user's reading interaction data and send it to the behavior analysis module through the processor. The user's experience interaction is then analyzed by the behavior analysis module. The user's reading immersion level is analyzed and uploaded to the management terminal through the processor. Finally, the management terminal is used to adjust the user's book push. The present invention realizes intelligent customization of the interactive experience of smart libraries through VR technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] Embodiment 1:

[0070] See also Figure 1-Figure 5 As shown, the present invention provides a technical solution: an intelligent library experience interaction system based on VR technology. The application scenario of the present invention is a place suitable for reading, such as a library or a home study room equipped with wearable devices. Preferably, a VR head display is a wearable device, and the wearable device is equipped with an intelligent library experience interaction system, such as Figure 1 As shown, the wearable device includes a display and a somatosensory device. The wearable device is also connected to an input device. The input device includes electronic devices such as a remote control, a handle, and a Bluetooth device for users to input commands. The somatosensory device includes a horizontal gyroscope and an eye tracker built into the VR head display. The system includes a wear detection module, a data acquisition module, a display adjustment module, a behavior recording module, a behavior analysis module, an execution module, a management terminal, a display, and a processor;

[0071] See also Figure 3 As shown, the wearing detection module is used to detect the wearing effect of the wearable device, and the detection process is as follows:

[0072] The real-time pressure of each pressure detection point of the wearable device and the real-time tension of the headband connection point are obtained. In this embodiment, the wearable device is composed of a device body and a headband with adjustable tightness, such as Figure 3 As shown, real-time pressure is obtained by installing a plurality of pressure sensors inside the device body, and real-time tension is obtained by installing a tension sensor at the connection of the headband;

[0073] Compare the real-time pressure of each pressure detection point with the standard pressure range;

[0074] If the real-time pressure at any pressure detection point belongs to the second standard pressure interval, a wearing adjustment signal is generated;

[0075] If the real-time pressures at each pressure detection point belong to the first standard pressure range, the real-time tensions at each headband connection point are compared with the standard tension range one by one;

[0076] If the real-time tension of any headband connection point does not belong to the standard tension range, a wearing adjustment signal is generated;

[0077] If the real-time tension of each headband connection point belongs to the standard tension range, a normal wearing signal is generated;

[0078] Among them, the values ​​of the first standard pressure interval and the second standard pressure interval are both greater than zero, and the values ​​of the first standard pressure interval are both less than the second standard pressure interval. It can be understood that when the real-time pressure of the pressure detection point belongs to the first standard pressure interval, the pressure between the contact point of the wearable device and the user's head will not cause discomfort, and when the real-time pressure of the pressure detection point belongs to the second standard pressure interval, the pressure between the contact point of the wearable device and the user's head will cause discomfort. When the real-time tension of the headband connection point is less than the value of the standard tension interval, the tightness of the headband is too loose, and when the real-time tension of the headband connection point is greater than the value of the standard tension interval, the tightness of the headband is too tight;

[0079] The wearing detection module sends a normal wearing signal or a wearing adjustment signal to the display. If the display receives the wearing adjustment signal, it reminds the user to adjust the wearing condition of the wearable device. If the display receives the normal wearing signal, it performs the subsequent steps.

[0080] See also Figure 4 and Figure 5 As shown, after the above adjustment is completed, after the user's authorization and consent, the data acquisition module is used to obtain the user's eye positioning data, the eye positioning data including the left pupil distance, the right pupil distance, the left eye pupil coordinates and the right eye pupil coordinates, the data acquisition module sends the user's eye positioning data to the processor, and the processor sends the user's eye positioning data to the display adjustment module;

[0081] like Figure 4 As shown, the display in the wearable device is composed of a left display screen and a right display screen, the left display screen is used to display the left eye image, and the right display screen is used to display the right eye image. In this embodiment, the eye positioning data is obtained by an eye tracker. Specifically, the left pupil distance is the shortest distance between the center point of the arc surface of the left display screen and the left eye of the user. Similarly, the right pupil distance is the shortest distance between the center point of the arc surface of the right display screen and the right eye of the user.

[0082] like Figure 5As shown, draw a straight line through the eye corners of the user's eyes, and mark the straight line as the horizontal axis of the facial coordinate system, connect the eye corners of the user's eyes, take the midpoint of the line segment as the origin of the facial coordinate system, and then draw a straight line through the origin and perpendicular to the horizontal axis as the vertical axis of the facial coordinate system, locate the center positions of the user's eye pupils according to the facial coordinate system to obtain the left eye pupil coordinates and the right eye pupil coordinates of the user;

[0083] The display adjustment module is used to adjust the position of the display in the wearable device. The adjustment process is as follows:

[0084] Map the geometric centers of the left and right display screens in the wearable device to the facial coordinate system, and obtain the left screen center coordinates marked as LX (x1, y1) and the right screen center coordinates RX (x2, y2). At the same time, obtain the user's left eye pupil coordinates LE (x3, y3) and right eye pupil coordinates RE (x4, y4);

[0085] Calculate the left screen offset value ZP and the right screen offset value YP of the wearable device according to the formula, the specific formula is as follows;

[0086]

[0087] Compare the left screen offset value and the right screen offset value of the wearable device with the offset somatosensory threshold;

[0088] If either the left screen offset value or the right screen offset value is greater than the offset somatosensory threshold, a focus adjustment signal is generated;

[0089] If the values ​​of the left screen offset value and the right screen offset value are both less than or equal to the offset somatosensory threshold, proceed to the subsequent steps;

[0090] Obtain the user's left pupil distance and right pupil distance and compare them with the standard pupil distance range;

[0091] If the values ​​of the left pupil distance and the right pupil distance both belong to the standard pupil distance range, no operation is performed;

[0092] If any value of the left pupil distance or the right pupil distance does not belong to the standard pupil distance interval, a pupil distance adjustment signal is generated;

[0093] Among them, the values ​​of the offset somatosensory threshold and the standard pupil distance interval are both greater than zero. In actual work, considering the screen size of the display and the user comfort, the standard pupil distance interval is set to a closed interval of ±10% of the standard pupil distance. The standard pupil distance = the diagonal length of the display screen × 10. Generally speaking, when watching VR images, the recommended viewing distance is ten times the screen diagonal.

[0094] The display adjustment module sends the focus adjustment signal or the pupil distance adjustment signal to the processor, and the processor sends the focus adjustment signal or the pupil distance adjustment signal to the execution module;

[0095] If the execution module receives a focus adjustment signal, it refocuses until the center of the user's pupil coincides with the center of the display screen; if it receives an interpupillary distance adjustment signal, it adjusts the front and rear position of the display until no signal is received;

[0096] When using the wearable device, the user can enter the virtual library through the virtual reality program. The wearable device displays several book covers. After the user selects a book cover, he can browse the book details page, which contains information such as the book title, author, and book type. When the user is on the book details page, he can choose to exit the book details page or read the book content further.

[0097] The behavior recording module is used to record the user's reading interaction data and send it to the processor, and the processor sends the user's reading interaction data to the behavior analysis module, and the reading interaction data includes the user's detail browsing number, content browsing number, and the total reading time of each book when the user reads, the number of command inputs, the number of blinks, and the number of posture adjustments. Among them, the number of detail browsing is the number of times the user browses the book detail page, the number of content browsing is the number of times the user reads the book content, the number of command inputs is obtained by recording data when the user inputs commands through an input device, the number of blinks is recorded by an eye tracker, and the number of posture adjustments is recorded by a horizontal gyroscope;

[0098] The behavior analysis module is used to analyze the user's experience interaction. The analysis process is as follows:

[0099] Get the total reading time RTi, the number of command inputs ZLi, the number of blinks KLi and the number of posture adjustments ZTi of each book when the user is reading, where i is the serial number of the book read by the user, the upper limit of i is n, and the value of n is equal to the value of the number of content browsing;

[0100] The user's behavioral focus value ZZi is calculated according to the formula. The formula is as follows:

[0101] Among them, s1, s2 and s3 are weight coefficients with fixed values, the values ​​of s1, s2 and s3 are all greater than zero and s1+s2+s3=1;

[0102] Obtain the number of detail views and content views of the user, divide the number of content views by the number of detail views to calculate the user's content reading ratio, and compare the user's content reading ratio with the content reading threshold;

[0103] If the value of the content reading ratio is less than or equal to the first content reading threshold, the effective reading coefficient of the user is determined to be the first effective reading coefficient;

[0104] If the value of the content reading ratio is greater than the first content reading threshold and less than or equal to the second content reading threshold, it is determined that the effective reading coefficient of the user is the second effective reading coefficient;

[0105] If the value of the content reading ratio is greater than the second content reading threshold, the effective reading coefficient of the user is determined to be the third effective reading coefficient;

[0106] Among them, the values ​​of the first content reading threshold and the second content reading threshold are both greater than zero, the first content reading threshold is less than the second content reading threshold, the effective reading coefficient reflects the proportion of the book content actually read by the user, the first effective reading coefficient is less than the second effective reading coefficient, and the second effective reading coefficient is less than the third effective reading coefficient;

[0107] The user's reading immersion value CJ is calculated according to the formula. The formula is as follows:

[0108] Wherein, QRr is the effective reading coefficient, and the values ​​of r include 1, 2, and 3, corresponding to the first effective reading coefficient, the second effective reading coefficient, and the third effective reading coefficient, respectively;

[0109] Compare the user's reading immersion value with the standard immersion interval;

[0110] If the reading immersion value belongs to the first standard immersion interval, the user's reading immersion level is determined to be the first reading immersion level;

[0111] If the reading immersion value belongs to the second standard immersion interval, the user's reading immersion level is determined to be the second reading immersion level;

[0112] If the reading immersion value belongs to the third standard immersion interval, the user's reading immersion level is determined to be the third reading immersion level;

[0113] Among them, the values ​​of the standard immersion intervals are all greater than zero, the value of the first standard immersion interval is less than the value of the second standard immersion interval, the value of the second standard immersion interval is less than the value of the third standard immersion interval, the reading concentration level of the first reading immersion level is lower than the reading concentration level of the second reading immersion level, and the reading concentration level of the second reading immersion level is lower than the reading concentration level of the third reading immersion level;

[0114] The behavior analysis module sends the user's reading immersion level to the processor, and the processor uploads the user's reading immersion level to the management terminal. The management terminal adjusts the user's book push according to the reading immersion level. The adjustment measures specifically include:

[0115] If the user's reading immersion level is the first reading immersion level, the book push frequency is increased;

[0116] If the user's reading immersion level is the second reading immersion level, the book push frequency is maintained;

[0117] If the user's reading immersion level is the first reading immersion level, the book push frequency is lowered;

[0118] It is understandable that if the user's reading immersion level is the first reading immersion level, the user's reading concentration is low, and the book push frequency needs to be increased so that the user can find the books he likes. If the user's reading immersion level is the third reading immersion level, the user's reading concentration is high, and the book push frequency needs to be reduced to ensure that the user focuses on the books being read.

[0119] In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.

[0120] Embodiment 2:

[0121] See also Figure 6 As shown, based on another concept of the same invention, a smart library experience interaction method based on VR technology is proposed, comprising the following steps:

[0122] Step S101: After the user finishes wearing the device, the wearing detection module detects the wearing effect of the wearable device, generates a wearing adjustment signal or a normal wearing signal and sends it to the display to prompt the user to adjust the wearing effect;

[0123] Step S102: The data acquisition module acquires the user's eye positioning data and sends it to the display adjustment module. The display adjustment module generates a focus adjustment signal or an interpupillary distance adjustment signal according to the eye positioning data analysis and sends it to the execution module. The execution module adjusts the position of the display according to the focus adjustment signal or the interpupillary distance adjustment signal.

[0124] Step S103, during the use of the wearable device, the user can enter the virtual library through the virtual reality program to perform reading interaction, and at the same time, the behavior recording module records the user's reading interaction data and sends it to the behavior analysis module via the processor;

[0125] Step S104, the behavior analysis module analyzes the user's experience interaction, and obtains the user's reading immersion level through the analysis and uploads it to the management terminal via the processor. The management terminal adjusts the user's book push according to the reading immersion level.
