As shown in fig. 1, an embodiment of the present invention introduces a method for adjusting screen parameters of a virtual reality headset, where a sensor is disposed on the virtual reality headset, and the method includes steps S1-S3.
S1: and detecting a first parameter of an image displayed on a screen through the sensor, and obtaining a first actual measurement value corresponding to the first parameter.
S2: and obtaining a preset expected value corresponding to the first parameter.
S3: and adjusting a screen parameter corresponding to the first parameter under the condition that the difference value between the first measured value and the preset expected value exceeds a preset range.
The sensor is arranged on the virtual reality head-mounted device, an image can be displayed on a screen of a user in the process of using the virtual reality device, and the sensor is used for detecting a first parameter of the image to obtain a first measured value corresponding to the first parameter. The preset expected value is obtained through a pre-test process, and when the image is displayed on the screen, if a first measured value corresponding to the first parameter obtained by detecting the first parameter of the image through the sensor is the preset expected value, the user is satisfied with the visual effect of the image display. And comparing the first measured value with a preset expected value, and judging whether the screen parameters need to be adjusted according to the comparison result. If the difference between the first measured value and the preset expected value exceeds the preset range, that is, if the difference between the first measured value and the preset expected value is larger, the user is not satisfied with the displayed image at the moment, and the screen parameter corresponding to the first parameter needs to be adjusted. If the difference between the first measured value and the preset expected value is within the preset range, the user is satisfied with the displayed image at the moment, and the screen parameter corresponding to the first parameter can be not adjusted.
According to the invention, whether the screen parameters need to be adjusted or not is judged according to the first actual measurement value and the preset expected value, when the difference between the first actual measurement value and the preset expected value is too large, the fact that the user is dissatisfied with the displayed image at the moment is indicated, the user is satisfied with the displayed image by adjusting the screen parameters, and the use experience of the user is improved.
In one embodiment of the present invention, the step S3 includes: acquiring preset screen parameters corresponding to the preset expected values; calculating the ratio between the preset expected value and the first measured value; calculating the product between the ratio and the preset screen parameter; and adjusting a screen parameter corresponding to the first parameter to be the product.
The preset screen parameters are obtained through a pre-test, and when the screen parameters are the preset screen parameters, the user is satisfied with the visual effect of the displayed image on the current screen. The invention judges whether to need to adjust the screen parameter according to the first actual measurement value and the preset expected value, when judging to need to adjust the screen parameter, firstly, the invention obtains the preset screen parameter corresponding to the preset expected value, and adjusts the screen parameter through the preset screen parameter. The dissatisfaction of the user with the displayed picture can be reflected by the ratio between the preset expected value and the first measured value. After the screen parameters are adjusted, the actual measured values corresponding to the screen parameters, which are required to be obtained by the sensors, are close to the preset expected values.
In one example, an image is first displayed on a screen according to a preset screen parameter a, at which time a first measured value X corresponding to the preset screen parameter a is detected by a sensor. And the preset expected value is Y, comparing the obtained first measured value X with the preset expected value Y, and if the screen parameter is judged to need to be adjusted, the adjusted screen parameter B is A (Y/X).
According to the invention, the dissatisfaction degree of the user on the displayed picture is reflected by the ratio between the preset expected value and the first measured value, and the product between the ratio and the preset screen parameter is used as the adjusted screen parameter corresponding to the first parameter, so that the display effect of the adjusted picture meets the requirement of the user, and the use experience of the user is improved.
In one embodiment of the present invention, the preset screen parameters are predetermined by: displaying a plurality of sample graphs according to screen parameters set by a wearer; prompting a wearer whether to set the set screen parameters as preset screen parameters; and after receiving the confirmation instruction, setting the screen parameters set by the wearer as the preset screen parameters.
The virtual reality headset device has a common mode and a test mode, a user can normally use the virtual reality headset device in the common mode, and preset screen parameters can be determined in the test mode. In the pre-test process, the user is prompted to set screen parameters, and the sample graph is displayed according to the screen parameters set by the user. And if the user is satisfied with the visual effect of the displayed sample graph, saving the screen parameters set by the user as preset screen parameters. If the user is not satisfied with the visual effect of the displayed sample graph, the user is allowed to reset the screen parameters. In the pre-test process, a plurality of different sample graphs can be displayed, and when the visual effect of the user is satisfied with all the sample graphs, the screen parameters at the moment are stored as preset screen parameters.
For example, three sample maps need to be displayed during the pre-test. Firstly, setting screen parameters by a user, sequentially displaying the three sample images by the virtual reality headset according to the screen parameters set by the user, and if the user is satisfied with the visual effect of displaying the three sample images, storing the screen parameters set at the moment by the user as preset screen parameters. If the user is not satisfied with the visual effect of displaying the sample map, the user is allowed to reset the screen parameters.
According to the invention, the screen parameters are adjusted by the user in the process of displaying the sample images, and the preset screen parameters are determined after the user is satisfied with the visual effects displayed by the plurality of sample images, so that the accuracy of the preset screen parameters is improved.
In one embodiment of the present invention, the preset expected value is predetermined by: displaying each sample graph when the current screen parameter of the screen is the preset screen parameter, and detecting a first parameter of the sample graph displayed on the screen through the sensor to obtain a second actual measurement value corresponding to the first parameter; and calculating the preset expected value according to all the second actual measured values.
The virtual reality headset device has a common mode and a test mode, a user can normally use the virtual reality headset device in the common mode, and a preset expected value can be determined in the test mode. In the pre-test process, a plurality of sample graphs are displayed according to preset screen parameters, second actual measurement values corresponding to the preset screen parameters are tested through a sensor when the sample graphs are displayed, one second actual measurement value is tested through the sensor for each sample graph, and finally all the second actual measurement values are comprehensively considered to obtain a preset expected value.
For example, three sample maps need to be displayed during the pre-test. Firstly, respectively displaying the three sample graphs according to preset screen parameters. When the first sample graph is displayed, a second actual measurement value X1 corresponding to a preset screen parameter is obtained through a sensor; when a second sample graph is displayed, a second actual measurement value X2 corresponding to a preset screen parameter is obtained through a sensor; and when the third sample graph is displayed, acquiring a second actual measurement value X3 corresponding to the preset screen parameter through the sensor.
According to the invention, the second actual measurement values are obtained through the sensors when each sample graph is displayed, and finally the preset expected value is calculated according to all the second actual measurement values, so that the accuracy of the preset expected value is improved.
In one embodiment of the present invention, the calculating the preset expected value according to all the second measured values includes: and calculating the average value of all the second actual measurement values, and setting the average value as the preset expected value.
The preset expected value is calculated according to the plurality of second actual measurement values, and visual effects of the display of the plurality of images need to be comprehensively considered, so that the preset expected value can be applied to various different images. For one sample graph, when the display effect of the sample graph is satisfied by a user, a second measured value is obtained through the detection of the sensor. The difference between the preset expected value and all the second measured values should be within a small range so that the visual effect that the user wishes to display the image can be reflected by the preset expected value, and the preset expected value can be applied to various different images. Taking the average value of all the second actual measurement values as the preset expected value can avoid the occurrence of overlarge difference between the second actual measurement values and the preset expected value.
For example, three sample graphs need to be displayed in the pre-test process, a second actual measurement value X1 when the first sample graph is displayed, a second actual measurement value X2 when the second sample graph is displayed, and a second actual measurement value X3 when the third sample graph is displayed are obtained through the sensor, and the finally calculated preset expected value Y is an average value of all the second actual measurement values, that is, (x1+x2+x3)/3.
According to the invention, the average value of all the second actual measurement values is used as the preset expected value, so that the display effect of the image can be satisfied by a user when the sensor detects the preset expected value, and the screen parameters are adjusted more accurately through the preset expected value, so that the use of the image is convenient for the user.
In one embodiment of the present invention, the method further comprises: acquiring biological information of the wearer; and correspondingly storing the biological information, the preset screen parameters and the preset expected values.
One piece of virtual reality headset can be used by multiple users, and the perception of color is different for different users, so different screen parameters are required to be configured for different users. When a user uses the virtual reality headset, if the user uses the virtual reality headset for the first time, the virtual reality headset collects biological information of the user, such as iris information and fingerprint information of the user. And then starting a test mode of the virtual reality head-mounted equipment, selecting preset screen parameters and preset expected values which are suitable for the user, and correspondingly storing the biological information of the user with the preset screen parameters and the preset expected values. When the user selects the normal mode of the virtual reality headset, the virtual reality headset can acquire biological information of the user, and then acquires corresponding preset screen parameters and preset expected values according to the biological information of the user.
In one example, a child and a adult share the same piece of virtual reality headset. When the dummy uses the virtual reality headset, since the dummy does not use the virtual reality headset for the first time, the dummy can normally use the virtual reality headset because the preset screen parameters and the preset expected values suitable for the dummy are already stored in the virtual reality headset. When the child uses the virtual reality headset, the child uses the virtual reality headset for the first time, and after wearing the virtual reality headset, the virtual reality headset acquires iris information of the child and then enters a test mode of the virtual reality headset. In the test mode, selecting preset screen parameters and preset expected values suitable for the child, and storing iris information of the child in correspondence with the selected preset screen parameters and preset expected values. After the child selects the common mode of the virtual reality headset, the virtual reality headset acquires iris information of the child, and acquires preset screen parameters and preset expected values which are stored in advance and correspond to the iris information of the child according to the iris information of the child, and the child is satisfied with the visual effects of all images displayed on the screen by adjusting the screen parameters.
According to the invention, the virtual reality head-mounted equipment acquires the biological information of the user, the biological information of the user is stored corresponding to the preset screen parameters and the preset expected values, and when one piece of virtual reality head-mounted equipment is used by a plurality of different users, all the users can experience the screen image suitable for color perception of the users, so that the use experience of the users is improved.
In one embodiment of the present invention, the sensor is an ambient light sensor, and the first parameter is brightness; or the sensor is a color temperature sensor, and the first parameter is a color temperature; or the sensor is an RGB sensor, and the first parameter is one of hue, brightness and saturation.
The ambient light sensor can record the brightness in the head-mounted cavity of the virtual reality head-mounted device, the brightness in the head-mounted cavity can be influenced by screens with different colors, and when different pictures are displayed on the screens, the brightness in the head-mounted cavity is also different. For example, a black picture is displayed on the screen and a white picture is displayed on the screen, and the brightness in the cavity is lower when the black picture is displayed than when the white picture is displayed. Some users prefer bright pictures, while some users prefer dark pictures.
The color temperature sensor may record the color temperature of the screen, which is a psychological perception of color by the user. Typically, red is a warm color and blue is a cool color. Some users prefer pictures with warm hues, while some users prefer pictures with cool hues,
the RGB sensor can record hue, brightness and saturation of the screen, the hue is used for distinguishing colors, the brightness is used for distinguishing brightness of the colors, the saturation is used for indicating vividness of the colors, and different users have different favorites on the parameters.
In one example, the first parameter is luminance. The user plays a game using the virtual reality headset, displays a game image on a screen, and detects the brightness at this time by the ambient light sensor to obtain a first measured value 100 corresponding to the brightness. A preset expected value corresponding to the luminance is obtained, for example, the preset expected value corresponding to the luminance is 150. If the preset range is (-10, +10), it is indicated that the user is satisfied with the visual effect of the displayed image when the brightness is in the range of 140-160. The difference between the first measured value and the preset expected value is 100 and is 50, and the difference exceeds the preset range, which indicates that for the game image displayed on the screen by the user at the moment is dark, the screen parameter corresponding to the brightness needs to be adjusted, that is, the brightness of the screen is adjusted, and the brightness of the screen can be increased.
According to the invention, whether the user is satisfied with the display effect of the image is judged according to the light intensity in the head-wearing cavity, the color temperature of the screen, the hue of the screen, the brightness of the screen and the saturation of the screen, and different parameters can be selected according to different favorites of the user, so that the virtual reality head-wearing device can be suitable for various different types of users, and is convenient for the user to use.
In one embodiment of the present invention, before the detecting, by the sensor, the first parameter of the image displayed on the screen, the method further includes: acquiring the next image to be displayed; acquiring first environmental information in a virtual scene corresponding to the next image to be displayed; acquiring second environmental information in the virtual scene corresponding to the currently displayed image; judging whether the first environment information is the same as the second environment information; in a different case, the next image to be displayed is displayed and the step of detecting, by means of the sensor, the first parameter of the image displayed on the screen is performed.
In the process of using the virtual reality device, the environment of the user may change in the virtual scene, for example, from a sunny environment to a cloudy environment. If the images are different in the same environment, the same screen parameters can be selected, and a better visual effect can be obtained for different image users. While for images in different environments, the user's visual experience may be affected if the same screen parameters are still used.
The corresponding relation between the image to be displayed and the environment information is pre-stored in the virtual reality equipment, and when the environment information needs to be acquired, the environment information corresponding to the image can be directly acquired from the corresponding relation. The environment information may be brightness of the environment in the virtual scene or may be color of the environment in the virtual scene.
In one example, a user plays a game using a virtual reality headset, the user being in a virtual game scene in which a plurality of different environments, such as a sunny environment and a cloudy environment, may be contained. In a sunny environment, the illumination intensity is high, while in a cloudy environment, the illumination intensity is low. If the environment changes from a sunny environment to a cloudy environment, the currently displayed image corresponds to the sunny environment, the next image to be displayed corresponds to the cloudy environment, the first environment information acquired by the virtual reality device is the cloudy environment, and the second environment information acquired by the virtual reality device is the sunny environment. The brightness of the screen can be properly adjusted at the moment due to higher illumination intensity in a sunny environment. After the screen is switched to the overcast environment, the illumination intensity in the overcast environment is lower, if the brightness of the screen is still kept unchanged, a high-brightness image is displayed on the screen, and the screen is inconsistent with the overcast environment, so that huge offence and sense can be brought to a user, and the brightness of the screen should be reduced at the moment.
The invention keeps the current screen parameters unchanged when the environment does not need to be switched in the virtual scene, does not need to adjust the screen parameters for each displayed image, reduces the adjustment times of the screen parameters, and improves the operation efficiency of the virtual reality head-mounted equipment. And meanwhile, when the environment needs to be switched in the virtual scene, the current screen parameters are adjusted, different screen parameters are applicable to different environments, and the use experience of a user is improved.
