Brief Description of the Drawings

[0045] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0046] Figure 1 is a structural block diagram of the system of the present invention;

[0047] Figure 2 is a flowchart of the method of the present invention. Detailed Embodiments

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0049] As Figure 1 shown, the present invention first provides an OSCE (Objective Structured Clinical Examination) nursing comprehensive assessment system based on scenario simulation, including an examinee service device, a consensus device, a plurality of scenario simulation interaction devices, and a plurality of invigilation devices.

[0050] A plurality of scenario simulation interaction devices are used to display a virtual examination scenario to examinees based on VR (Virtual Reality) technology, receive the operation feedback of the examinees, and adjust the virtual examination scenario based on the operation feedback.

[0051] A candidate service device is used to obtain and verify candidate identity information, and generate a task distribution instruction after successful verification. The task distribution instruction is used to establish an association relationship between the candidate identity information and the scenario simulation interaction device.

[0052] Multiple invigilation devices are used to obtain a virtual exam scenario and display it to the examiner in the form of a video, and receive the scoring results of the examiner.

[0053] A consensus device is used to obtain all the scoring results and generate an assessment result based on all the scoring results.

[0054] Before the assessment, the candidate first uploads the candidate identity information through the candidate service device, and prepares for the assessment after the candidate service device successfully verifies the candidate identity. At this time, the candidate service device generates a task distribution instruction, specifying that the candidate starts the assessment on one of the scenario simulation interaction devices. After the assessment starts, the scenario simulation interaction device is used to display the pre-constructed virtual exam scenario to the candidate, and the candidate operates the scenario simulation interaction device to achieve simulated operations in the virtual exam scenario. When the candidate makes an operation, the scenario simulation interaction device adjusts the virtual exam scenario and generates a real-time exam video, and at the same time sends the real-time exam video to the invigilation device, so that the examiner can supervise the assessment process through the invigilation device and score the candidate's operation feedback. The examiner can give a score to each operation feedback of the candidate, and all the scores given by one examiner to one candidate are summarized as the scoring result. After the candidate finishes the assessment, the invigilation device sends the scoring result to the consensus device, and the consensus device generates an assessment result by synthesizing all the examiners' scoring results.

[0055] The present invention can display a virtual exam scenario to the candidate based on VR technology, and adjust the virtual exam scenario in real time according to the candidate's operation feedback, without the need to specially prepare a real exam scenario, which can improve the assessment efficiency and will not affect the assessment result due to the poor accuracy of the real exam scenario; the present invention can be used for multiple candidates to take the assessment at the same time, and can also be used for multiple examiners to supervise and score the assessment process at the same time, further improving the assessment efficiency; the present invention can synthesize the scoring results of multiple examiners to generate a more accurate assessment result, so as to more accurately evaluate the candidate's nursing skill level.

[0056] Further, the scenario simulation interaction device includes a VR helmet, a human-computer interaction module, and a data processing module. The VR helmet is used to display a virtual exam scenario to the examinee based on VR technology. The human-computer interaction module is used to receive the operation feedback of the examinee. The data processing module is used to adjust the virtual exam scenario based on the operation feedback. It should be noted that the scenario simulation interaction device can use existing devices such as VR game consoles, which belong to the prior art and will not be elaborated here. Before the formal assessment, examinees can be organized to practice in the scenario simulation interaction device so that they can perform more efficient and accurate operations based on the human-computer interaction module during the assessment, and prevent examinees from affecting the assessment process due to unfamiliarity with the scenario interaction simulation device.

[0057] Further, the examinee service device includes an identity acquisition module and an identity verification module. The identity acquisition module is used to acquire the examinee's identity information, including an information input unit and a document reading unit. The identity verification module is used to compare the examinee's identity information with a pre-constructed examinee database. If the comparison is successful, the verification result is successful; otherwise, the verification result is failed. Based on this examinee service device, the present invention can use the document reading unit to acquire the examinee's identity information by reading the examinee's ID card, student ID card or other identity documents, and the examinee can also manually input the examinee's identity information using the information input unit. Among them, the method of reading identity documents is more efficient, and the examinee's manual input of identity information can ensure that the examinee can still take the assessment smoothly when the identity document expires.

[0058] The invigilation device includes a display module and a collection module. The display module is used to display the virtual exam scenario to the examiner in the form of a video. The collection module is used to receive the scoring results of the examiner. In actual implementation, the invigilation device can be based on existing devices such as smartphones, tablets or ordinary computers.

[0059] To fully ensure the fairness of the assessment process, the invigilation device is also used to receive the question assignment results of the examiner and control the scenario simulation interaction device to display the virtual exam scenario to the examinee according to the question assignment results. That is to say, the examiner can use the invigilation device to select questions and determine the final assessment questions based on the selection results of all examiners. For example, if more than half of the examiners select the same question, then this question is used as the final assessment question.

[0060] As Figure 2 shown, the present invention further provides a method for an OSCE nursing comprehensive assessment system based on scenario simulation, which is implemented by using an OSCE nursing comprehensive assessment system based on scenario simulation as described above. The method includes S1 to S6.

[0061] S1. Use the candidate service device to obtain the candidate's identity information and perform verification. If the verification passes, generate a task distribution instruction; otherwise, abort. More specifically, the method for using the candidate service device to obtain the candidate's identity information is as follows: The candidate service device attempts to read the candidate's identity document. If the reading is successful, the candidate's identity information is obtained; if the reading fails, the candidate is reminded to manually enter the candidate's identity information. That is to say, the candidate service device first attempts to read the candidate's identity document through the document reading unit. If the reading is successful, the acquisition of the candidate's identity information is completed; otherwise, the candidate is reminded to manually enter the candidate's identity information. After obtaining the candidate's identity information, the candidate service device compares the candidate's identity information with a pre-constructed candidate database. If the comparison is successful, the verification result is successful, that is, if the same candidate identity information is recorded in the candidate database, the verification result is successful; otherwise, the verification result is failed.

[0062] Furthermore, if the verification result is failed, the candidate service device can remind the candidate to try using the identity document again or manually enter. If the verification results of the candidate's multiple attempts are all failed, the candidate service device will no longer serve this candidate, and at the same time send a warning message to at least one invigilation device to remind the examiner to handle it. After receiving the warning message, the examiner can use the invigilation device to send a re-verification message to the candidate service device so that the candidate can start entering the candidate's identity information again, and the candidate service device performs the verification.

[0063] S2. The candidate service device sends the task distribution instruction to the scenario simulation interaction device, establishes an association relationship between the scenario simulation interaction device and the candidate's identity information, and displays it to the candidate, enabling the candidate to select the correct scenario simulation interaction device to start the assessment to ensure the smooth progress of the assessment process.

[0064] S3. After the candidate activates the scenario simulation interaction device, use the scenario simulation interaction device to display a virtual exam scenario to the candidate. The method for using the scenario simulation interaction device to display a virtual exam scenario to the candidate includes S31 to S36.

[0065] S31. The scenario simulation interaction device sends a question determination request to the invigilation device. The question determination request is for random questions and designated questions. The question determination request is used for the examiner to select the way of determining questions. The determination method is random or designated, which is selected by the examiner through the invigilation device. The specific process is as follows.

[0066] S32. Use the invigilation device to display the question determination request to the examiner and wait for the examiner to select.

[0067] S33. After the invigilation device obtains the result selected by the examiner, it generates a test question feedback message, which is a random test question or a specified test question. When the examiner selects a specified test question, the invigilation device can display a pre-constructed test question list to the examiner for selection.

[0068] S34. The invigilation device sends the test question feedback message to the scenario simulation interaction device.

[0069] S35. The scenario simulation interaction device sorts all the test question feedback messages and selects the one with the highest frequency as the basis for setting questions.

[0070] S36. The scenario simulation interaction device calls the pre-constructed virtual exam scenario based on the question-setting basis and displays it to the examinee.

[0071] In S3, the scenario simulation interaction device determines the way to select test questions through a test question determination request. If the examiner selects a random test question, the test question feedback message returned by the invigilation device to the scenario simulation interaction device is also a random test question. If the examiner selects a specified test question, the test question feedback message returned by the invigilation device to the scenario simulation interaction device is the mark of the test question in the test question bank. The scenario simulation interaction device makes statistics after receiving all the test question feedback messages from the invigilation devices, that is, it counts the number of random test questions and test question marks, and then sorts them in descending order of the number. After that, the scenario simulation interaction device selects the first sorting result and generates a question-setting basis. The final form of the question-setting basis is a random test question or a test question mark. If the question-setting basis is a random test question, the scenario simulation interaction device randomly selects a test question in the test question bank and displays the corresponding virtual exam scenario to the examinee. If the question-setting basis is a test question mark, the scenario simulation interaction device selects the virtual exam scenario corresponding to the mark in the test question bank and displays it to the examinee.

[0072] Based on S3, the way to determine test questions is more flexible, and it can also prevent a single examiner from specifying test questions for a certain examinee, which can ensure the fairness of the assessment process.

[0073] S4. Use the scenario simulation interaction device to receive the operation feedback of the examinee, adjust the virtual exam scenario based on the operation feedback, and at the same time send the adjusted virtual exam scenario to the invigilation device in the form of a video.

[0074] Further, after the scenario simulation interaction device adjusts the virtual exam scenario based on the operation feedback, it generates a real-time exam video, and determines multiple key frames in the real-time exam video. After the key frames are determined, the real-time exam video is sent to all invigilation devices. During the OSCE comprehensive nursing assessment process, there are many links and operations that candidates need to complete. Between different links or different operations, candidates may not need to perform any actions, and this part of the time can be recorded as invalid time. Correspondingly, in the real-time exam video, the part corresponding to the invalid time also has no value for scoring. Moreover, since the number of examiners is usually much smaller than the number of candidates, and the present invention supports multiple candidates to take the assessment simultaneously, in order to further improve the assessment efficiency, the present invention sets a key frame mechanism in the real-time exam video. By adding key frames to the real-time exam video, when the examiner watches the real-time exam video through the invigilation device, they only need to focus on the key frame part, because the key frame part contains the key links and operations of the assessment.

[0075] Further, after the scenario simulation interaction device determines the key frames, it adds key marks to the key frames. The key marks are geometric patterns or video masks. When the key mark is a geometric pattern, it can be displayed at the edge position of the key frame. When the key mark is a video mask, a colored border can be selected and added to the key frame.

[0076] S5. Use the invigilation device to display the virtual exam scenario in video form to the examiner and receive the scoring results of the examiner. Based on the above key frame mechanism, for the multiple real-time exam videos corresponding to multiple candidates taking the assessment simultaneously, the invigilation device can display them in partitions on the same screen. Each area corresponds to a real-time exam video. And when the real-time exam video plays to a key frame, it automatically pauses. The examiner scores the candidate based on the key frame part. After the scoring is completed, the real-time exam video continues to play and automatically pauses when it reaches the next key frame. Through this method, the examiner can score multiple candidates simultaneously, and will not miss any key links and operations of the candidates, ensuring the accuracy of the scoring results and the fairness of the assessment.

[0077] On the other hand, when multiple key frames are consecutive, they can form a key video segment. When the real-time exam video plays to the first key frame of the key video segment, it automatically pauses. Furthermore, when the examiner selects the area corresponding to the real-time exam video, the key video segment is normally played in that area and automatically pauses after playing to the last key frame. Through this method, the examiner can watch multiple key frames continuously without watching frame by frame, which can effectively improve the assessment efficiency. In addition, the examiner can control the playback of the key video segment by selecting the area, ensuring that the examiner can observe every key video segment of every candidate.

[0078] S6. Use the consensus device to obtain all the scoring results and generate an assessment result based on all the scoring results. The method by which the consensus device generates an assessment result based on all the scoring results includes S61 to S64.

[0079] S61. The consensus device decomposes the scoring result sent by each invigilation device to obtain multiple score arrays corresponding one by one to the invigilation devices. As described above, in order to fully ensure the accuracy of the assessment result in the present invention, the examiner needs to score each key link and operation of the examinee, and correspondingly generate multiple scores, and these scores can be combined into a scoring result corresponding to the examinee. After receiving the scoring result, the consensus device needs to first decompose the scoring result, so as to accurately master the scores given by each examiner for each key link and operation of the examinee, and then be able to generate a more accurate assessment result.

[0080] S62. The consensus device generates a score matrix based on all the score arrays. In the score matrix, each column corresponds to a scoring result, the elements in a column correspond one by one to the scores, and each row is the scores given by multiple examiners for the same link or operation of the examinee.

[0081] S63. The consensus device obtains an optimized matrix after optimizing each element of the score matrix. Specifically, optimize the elements of each row, because the elements in each row are the scores of the same link or operation of the examinee. By optimizing the elements row by row, it is possible to avoid the scores given by different examiners for the same link or operation of the examinee from being too different, thus affecting the final assessment result. The optimization method can include the following steps.

[0082] S631. Delete the maximum and minimum values of the elements in each row to avoid the adverse impact of extreme scores on the assessment result.

[0083] S632. Rearrange the remaining elements in each row in descending order, but do not change the positions of the elements, that is, do not change the positions of the scores in the score matrix.

[0084] S633. Calculate the difference between two adjacent elements after the remaining elements in each row are rearranged. If the difference exceeds a preset threshold, and the position of the first element among the two adjacent elements is in the front or the position of the second element is in the back, then delete all the elements before the first element, or delete all the elements after the second element. By this means, the outliers in a row of elements can be further removed.

[0085] S634. Calculate the mean value of the remaining elements in each row.

[0086] S64. The consensus device generates an assessment result based on the optimization matrix. Through the previous process, the elements in each row will be normalized, that is, the scores obtained by the examinee in each link or operation will be normalized, and the normalization process is not interfered by the maximum and minimum values, ensuring that the normalized elements, that is, the normalized scores, can more accurately reflect the examinee's skill level. After the score matrix undergoes the above normalization process, it will form a one-column array, and the sum of all scores can be calculated to obtain the final assessment result.

[0087] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0088] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
