Description

Technical Field

[0001] This invention relates to the field of electronic product technology, and more specifically, to a color blindness detection method and head-mounted device. Background Technology

[0002] Normally, the human eye contains three types of cone cells, which can distinguish red, green, or blue. Color is perceived when these cone cells sense different amounts of the three primary colors. A lack of any type of cone cell or abnormal cone cell function leads to color blindness. Color-blind individuals cannot distinguish one of the three primary colors, or may misidentify the shade of that color, or even perceive it as a completely different color.

[0003] Currently, routine color blindness testing mainly uses manual supervision, where the tester reads the numbers or graphics displayed on the color blindness test card to determine whether the tester is colorblind. This method has certain drawbacks, namely, when the tester is nervous or not focused enough, it is easy to misread the test card. It is not only inefficient, but also lacks standardized testing criteria, which can easily lead to a certain degree of misjudgment. Summary of the Invention

[0004] In view of the above problems, the purpose of this invention is to provide a color blindness detection method and head-mounted device to solve the problems of low efficiency, high labor costs, inconsistent detection standards, and easy misjudgment in existing color blindness detection methods.

[0008] In addition, an optional technical solution is that the creation of the color blindness detection image set and the display mode corresponding to the detection image set includes: creating a first detection image set and determining that the display mode corresponding to the first detection image set includes displaying multiple images sequentially at a preset time interval; creating a second detection image set and determining that the display mode corresponding to the second detection image set includes displaying multiple images simultaneously, and guiding the user to be tested to adjust the order of the multiple images; creating a third detection image set and determining that the display mode corresponding to the third detection image set includes displaying multiple images simultaneously, and guiding the user to be tested to select a target image.

[0009] In addition, an optional technical solution is that, after displaying the detection image set, the method further includes: indicating the question corresponding to the current display mode to the user to be tested in the form of text; or indicating the question corresponding to the current display mode to the user to be tested in the form of voice broadcast; the user to be tested can answer the questions by clicking, gazing, gestures, and voice.

[0010] In addition, an optional technical solution is that the first detection image set includes numbers or graphics formed by color dots of different colors and brightness; the second detection image set includes color blocks / images arranged in a color gradient or matching color sequence; and the third detection image set includes images of different colors.

[0011] In addition, an optional technical solution is to obtain the detection result corresponding to the detection image set, including: recording the answer and reaction time provided by the user to be detected; and determining the detection result corresponding to the detection image set based on the answer and the reaction time.

[0013] In addition, an optional technical solution is that the color blindness parameters include: color blindness type, color blindness level, test score and analysis results; the color blindness type includes red-green color blindness, yellow-blue color blindness, red color blindness, green color blindness and total color blindness.

[0014] On the other hand, the present invention also provides a head-mounted device for use in the above-described color blindness detection method; wherein the head-mounted device includes VR glasses.

[0015] Using the aforementioned color blindness detection method and head-mounted device, different forms of color blindness detection image sets and display modes can be created.

However, these aspects indicate only a few of the various ways in which the principles of the invention can be used. Furthermore, the invention is intended to encompass all such aspects and their equivalents. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the following description, numerous specific details are set forth for illustrative purposes and to provide a thorough understanding of one or more embodiments. However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

Therefore, they should not be construed as limiting the content or structure of this invention.

[0023] With the rapid development of VR technology, VR devices have entered the lives of many consumers. Among them, head-mounted displays, as a type of virtual reality head-mounted display device, are generally divided into external head-mounted displays, all-in-one head-mounted displays, and mobile head-mounted displays. They mainly use head-mounted displays to close off a person's vision and hearing from the outside world, guiding the user to feel as if they are in a virtual environment. The display principle is that the left and right eye screens display images for the left and right eyes respectively. After the human eye obtains this information with differences, it generates a sense of stereoscopic effect in the brain.

[0024] Therefore, to address the problems of low efficiency, high labor costs, inconsistent testing standards, and susceptibility to misjudgments in existing color blindness detection methods, this invention provides a color blindness detection method and head-mounted device. Based on VR devices, different forms of color blindness detection image sets and display modes can be created. Then, the target head-mounted device displays each detection image set according to the corresponding display mode. After the user wears the target head-mounted device, they answer questions based on the displayed content. The relevant color blindness parameters of the user are determined based on the answer results. This method enables automated color blindness detection, is easy to operate, and has high consistency across different users, effectively reducing misjudgments and improving detection accuracy.

[0025] To describe in detail the structure of the color blindness detection method and head-mounted device of the present invention, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Figure 1 and Figure 2 Schematic flowcharts of color blindness detection methods according to embodiments of the present invention are shown respectively.

[0027] like Figure 1 and Figure 2 As shown in the figure, the color blindness detection method of this invention mainly includes:

[0028] S110: Select and calibrate the target head-mounted device.

[0029] Specifically, a head-mounted device with a resolution greater than a preset value can be selected as the target head-mounted device. Then, the color, brightness, and contrast parameters of the target head-mounted device are calibrated to ensure that all parameters of the target head-mounted device meet the detection requirements before testing. Among these, a head-mounted device with a high-resolution display can be selected to ensure the accuracy of color blindness detection.

[0030] The target head-mounted device may include VR / AR glasses or similar electronic devices with a display screen. The display screen of the target head-mounted device can display relevant questions for color blindness testing so that the wearer can complete the relevant color blindness test.

[0031] In one specific embodiment of the present invention, the color blindness detection method further includes: adjusting the left and / or right lens barrels of the target head-mounted device according to the position information of the two pupils of the user to be tested, so as to adjust the IPD (Interpupillary Distance) of the target head-mounted device, thereby meeting the wearing needs of different users and ensuring the accuracy of the detection.

[0032] Specifically, the adjustment process for the IPD of the head-mounted device may include: first, adjusting the interpupillary distance (IPD) between the left and right lenses of the target head-mounted device to the minimum value; then, controlling the left and right lenses to move in opposite directions, and receiving reflected signals from the wearer's eyes via infrared sensors during the movement; when the reflected signal changes from the sclera to the pupil, recording the current first distance; then, controlling the left and right lenses to continue moving in opposite directions, and receiving reflected signals from the wearer's eyes via infrared sensors during the movement; when the reflected signal changes from the pupil to the sclera, recording the current second distance; then, based on the first and second distances, the target IPD of the target head-mounted device can be determined, and the positions of the left and right lenses can be adjusted based on the target IPD and the initial positions of the left and right lenses.

[0033] It can be seen that the second distance minus the first distance represents the width of the wearer's pupil, and half of the second distance minus the first distance represents the distance of half of the wearer's pupil. Then, by adding the first distance to this half-pupil distance and the initial distance between the center line between the left and right lens barrels and the infrared sensor when the interpupillary distance is at its minimum, half of the distance between the centers of the wearer's two pupils can be represented. Finally, the target interpupillary distance of the target head-mounted device can be determined. It can check the position of the wearer's pupil center by using the principle that the reflectivity of infrared light by the white of the eye and the pupil is different, so as to adjust the interpupillary distance parameter between the two lens barrels of the head-mounted device. It can realize automatic adjustment of the interpupillary distance according to different wearers, and improve the accuracy of color blindness detection.

[0034] S120: In the target head-mounted device, a color blindness detection image set and a display mode corresponding to the detection image set are created.

[0035] Specifically, the step further includes: creating a first detection image set and determining a display mode corresponding to the first detection image set, which includes displaying multiple images sequentially at preset time intervals; creating a second detection image set and determining a display mode corresponding to the second detection image set, which includes displaying multiple images simultaneously, and guiding the user to be detected to adjust the order of the multiple images; and creating a third detection image set and determining a display mode corresponding to the third detection image set, which includes displaying multiple images simultaneously, and guiding the user to be detected to select a target image.

[0036] It is known that different detection image sets correspond to different types of detection questions. By flexibly setting the detection image sets, multi-faceted detection of color blindness can be achieved, enriching the detection types and improving the accuracy of the detection. Among them, the first detection image set may include numbers or graphics formed by color dots of different colors and brightness, such as the Ishihara diagram; the second detection image set includes color blocks / images with color gradients or matching color sequences; the third detection image set includes images of different colors, such as the fragrance diagram.

[0037] Among them, the Ishihara diagram can display numbers or graphics formed by dots of different colors and brightness. Depending on the range of colors that colorblind patients cannot perceive, they may have difficulty distinguishing these numbers or graphics. This type of question belongs to the pattern recognition category. The aroma diagram can display images or samples of different colors. Users need to select or identify specific colors according to the question instructions. However, colorblind patients may not be able to correctly identify or match colors. This type of question belongs to the selection task. The color arrangement requires users to arrange color blocks in order of color gradient or matching colors. The difficulty that colorblind patients show in distinguishing colors can reveal the type of colorblindness. This type of question belongs to the sorting task.

[0038] It should be noted that after displaying the detection image set, the process may also include: instructing the user to be tested on the questions corresponding to the current display mode in the form of text; or instructing the user to be tested on the questions corresponding to the current display mode in the form of voice broadcast; the user to be tested can answer questions by clicking, looking, gesturing and speaking, and the answering process can be completed through various methods such as the controller of the head-mounted device or the built-in voice function, and is not limited to the above methods.

[0039] Furthermore, with the continuous development and improvement of color blindness detection methods, the detection image set can be updated, optimized, added, or deleted at any time through head-mounted devices, thereby ensuring the continuous accuracy of color blindness detection.

[0040] S130: Display the detection image set through the target head-mounted device according to the display mode, and guide the user to be tested to answer questions based on the displayed content.

[0041] Specifically, after the above steps are completed, the user to be tested can complete the relevant tests by wearing the target head-mounted device. At the same time, it is also necessary to ensure that the user to be tested is in a quiet and evenly lit environment. Adjusting the testing environment includes soft indoor lighting and strong outdoor lighting. In addition, by adjusting the state of the testing environment, the user's color blindness status under different ambient light conditions can also be detected, which helps to improve the diversity of the test results.

[0042] Then, the target head-mounted device displays the detection image set according to the display mode. For example, the first detection image set can be displayed one by one at a preset time interval, while the second detection image set can be displayed multiple times at once, and the third detection image set can also be displayed multiple times at once, which is convenient for users to sort and answer or select answers, etc., so as to display in the corresponding mode according to the detection image set (different detection types).

[0043] S140: Obtain the detection result based on the answer result corresponding to the detection image set, and determine the color blindness parameter of the user to be detected based on the detection results of all detection image sets.

[0044] This step further includes: recording the answers and corresponding reaction times of each question provided by the user to be tested; determining the detection results corresponding to the detection image set based on the answers and reaction times, storing and finally displaying them; determining the final color blindness parameters based on the detection results of all detection image sets; recording the user's every step of the test data in as much detail as possible; analyzing the detection results; comparing the user's answers with the standard answers; identifying the type and severity of color blindness; and finally generating a report including the type of color blindness, test score, and analysis results.

[0045] Specifically, since the types of detection image sets are different, weights can be configured for each detection image set. Based on the detection results of each detection image set and the corresponding weights, the color blindness parameters of the user to be tested are determined. These color blindness parameters include: color blindness type, color blindness level, test score, and analysis results; color blindness types include red-green color blindness, yellow-blue color blindness, red color blindness, green color blindness, and total color blindness.

[0046] Corresponding to the above-described color blindness detection method, the present invention also provides a head-mounted device for use in the above-described color blindness detection method; wherein, the head-mounted device may include VR glasses, AR glasses, or other head-mounted devices with a display screen.

[0047] It should be noted that the embodiments of the head-mounted device described above can be referred to the description in the embodiments of the color blindness detection method, and will not be repeated here.

[0048] Based on the aforementioned color blindness detection method and head-mounted device, different forms of color blindness detection image sets and corresponding display modes are created using a head-mounted device with display functionality. Each image set is then displayed according to its corresponding display mode. Users wearing the target head-mounted device can answer questions based on the displayed content. Finally, the relevant color blindness parameters of the user are determined based on the answer results. This method enables automated color blindness detection, is easy to operate, allows for real-time updates of the detection image sets, and provides high consistency across different users, effectively reducing misjudgments and improving detection accuracy and flexibility.

[0049] The color blindness detection method and head-mounted device according to the present invention have been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the color blindness detection method and head-mounted device proposed in the present invention without departing from the scope of the invention.
