Detailed Description

The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.

The first embodiment is as follows:

as shown in fig. 1, the present embodiment provides an information processing method, including:

step S110: acquiring visual condition parameters of a user;

step S120: acquiring the visual distance and/or visual angle of a user relative to a display unit;

step S130: determining a pre-filtering parameter according to the visual condition parameter and the visual distance and/or the visual angle;

step S140: and adjusting the light field of the display unit according to the pre-filtering parameter.

The information processing method described in this embodiment can be applied to various electronic devices with light field display units. The electronic device can be a mobile phone, a tablet computer, a wearable device or an electronic book, and is particularly suitable for a personal electronic device watched by a small number of users. The personal electronic device to which the information processing method of this embodiment can be applied may include a mobile phone, a tablet computer, an electronic book, or a personal computer.

The visual condition parameters in the present embodiment may include various parameters characterizing the visual condition of the user, for example, a visual defect parameter capable of characterizing the visual defect of the user.

In this embodiment, the step S110 may acquire the visual condition parameters of the user, and may include: visual condition parameters are received for input from a human-machine interaction interface. The visual condition parameter can be various information for representing the visual condition of the user, such as the degree of glasses worn by the user and information such as the visual test value of the user, which are received from the man-machine interaction interface. In step S110, by receiving the information, it can be analyzed whether the user has a problem of visual defects or what visual defects exist; severity of visual impairment, etc.

In step S120, a distance between the user and the display unit when the user is currently viewing the display unit is obtained, and the distance is referred to as a viewing distance in this embodiment, and a viewing angle between the user and the display unit is also obtained, and the viewing angle is directly referred to as a viewing angle in this embodiment. The viewing distance and the viewing angle can apply various viewing feelings such as the definition of the user viewing. In step S120, information such as a distance from the user to the display unit and a viewing angle with respect to the display unit may be determined by image acquisition using a three-dimensional image acquisition unit.

In step S130, the pre-filtering parameter is determined in combination with the visual condition parameter and at least one of the viewing distance and the viewing angle of the display unit currently viewed by the user. The pre-filtering parameter may include parameters such as the phase of light displayed by the display unit, so that a display screen most suitable for the current user can be obtained. On the one hand, the visual defect protection device can be used for visual defect users to improve the viewing feeling of the users such as viewing definition and the like, and on the other hand, aiming at some non-visual defect users, the visual defect phenomenon caused by long-term viewing of the users when the visual distance or the visual angle is inappropriate is reduced, so that the vision of the users is protected.

For example, by finding in step S110 that the user is a visually impaired person such as near-sighted or far-sighted, the light field of the display unit will be adjusted after the pre-filtering parameter applicable to the visually impaired user at the current viewing position in step S130. In this embodiment, adjusting the light field may include adjusting parameters such as phase, light intensity, and color tone of the light output by the display unit, so that the picture displayed by the display unit can be more clearly displayed in the eyes of the visually impaired user, thereby obtaining better viewing experience of the user.

For another example, it is found that the user has normal eyesight through step S110, but the visual distance and the visual angle are obtained through the combination of the steps, the user may be closer to the display unit, and in order to reduce the frequency of the visual defect caused by long-time viewing of the user, in this embodiment, the corresponding pre-filtering parameter is determined to adjust the light field, so as to reduce the problem of the visual defect caused by long-time viewing at an improper position.

Example two:

step S110: acquiring visual condition parameters of a user;

The step S110 includes:

outputting vision test information;

collecting user feedback information based on the vision test information;

The vision test information may be a vision test icon. A common standard logarithmic visual chart is shown in fig. 2. After outputting the vision test information, user test answers may be collected. Acquiring user gestures through a camera to obtain user test answers; for example, the voice of the user is collected by using an audio collection device, and information such as a test answer of the user is obtained. The user tests one of the user feedback information, and the user feedback information may further include information such as reply information indicating whether the user can view part or all of the clearly displayed vision test information. In summary, the user feedback information can represent the vision test result of the user viewing the vision test information at the current position.

Further, whether the vision of the user is defective or not, or what defect or degree of vision defect exists can be determined according to the feedback information of the user, the visual distance and/or the visual angle during the test; in this way, the visual condition parameters are simply and accurately acquired.

In the specific implementation process, the user identification information can be stored and the vision condition information of the user can be obtained, so that when the same user watches the electronic equipment next time, the vision test is not required to be carried out at every time, the time and the operation spent in the vision test are reduced, the processing operation of the information processing method of the embodiment is simplified, and the processing efficiency is improved. Of course, in order to avoid the transition of the vision condition of the user, the vision condition of the user can be determined at regular time when the user is in specific implementation, unlike the stored example condition information. For example, the effective time of the visual condition parameter determined by one vision test of the user is specified, and if the specified time is exceeded, the vision of the user needs to be retested.

In summary, the present embodiment provides a method for easily and accurately acquiring the vision parameters of the user. The left diagram in fig. 3 is a schematic view of the viewing effect of the user viewing the vision test information before the light field is not adjusted; the right diagram of fig. 3 is a schematic view of the viewing effect of the user viewing the vision test information after adjusting the light field. As can be seen from the comparison in fig. 3, after the light field is adjusted, the viewing clarity is obviously improved for the user with visual impairment.

Example three:

step S110: acquiring visual condition parameters of a user;

The step S110 may include:

collecting user identification characteristics;

If the electronic device stores some visual condition information of the user in advance, for example, the electronic device receives some visual condition information of the user from the human-computer interaction interface in advance, or obtains the visual condition parameters of the user by using the method described in the second embodiment. In this embodiment, a user identification feature is first collected, where the collecting of the user identification feature includes receiving user identification information such as a user name input by a user, and may also collect user voiceprint or fingerprint biometric information. In any case, an identification feature that can identify the user. After the user identification features of the user are collected, the visual condition information of the current user can be obtained by inquiring the pre-stored visual condition information.

As a further improvement of this embodiment, the acquiring the user identification features may include: the facial features of the user are collected. In the embodiment, the image collector can be used for collecting the face image of the user, and the face characteristics of the user are obtained through the face recognition technology. In step S120, an image collector may also be used to collect images of the user, and the viewing angle and/or the viewing distance are determined through the images, so that step S110 and step S120 may multiplex the same frame of image to obtain the user identification feature and the viewing angle and/or the viewing distance. Therefore, the operation of the electronic equipment can be simplified, and the images needing to be collected are reduced.

Example four:

step S110: acquiring visual condition parameters of a user;

As shown in fig. 4, step S120 may include:

step S121: acquiring a user image by using an infrared camera;

step S122: and analyzing the user image, and determining the visual distance and/or visual angle of the user relative to the display unit.

In the present embodiment, it is to be utilized to capture user images, and the position relationship between the infrared camera and the display unit is generally known in the present embodiment, and in order to simplify the analysis of the viewing distance and the viewing angle, the infrared camera is generally disposed at the same position as the display unit, for example, the image capture unit is disposed integrally with the display unit. After the user image is acquired, the user image is analyzed, and in combination with various acquisition parameters, such as a focal length, the distance of the user relative to the display unit (i.e., the viewing distance) can be calculated, and then the angle of view of the user relative to the display unit can be determined by analyzing the acquired user image. Typically in this embodiment the captured user image comprises at least the user's eye. When image acquisition is performed, the electronic device may output prompt information to prompt that the user views the display screen in front, so that when the infrared camera acquires the user' S eyes through a preview image obtained by image preview, the corresponding preview image is stored, and it is determined that the user image in step S120 is completed.

Of course, in the embodiment, the user image is collected by using the infrared camera, and in a specific implementation, parameters such as a visual distance and/or an angle of view of the user's eyes relative to the display unit may be determined by using an eye tracker, a user pupil tracking technology, and the like, which is not limited to the above-mentioned method. The infrared camera in the embodiment is only used for collecting the user image to obtain the visual distance and/or the visual angle, and the infrared camera has the characteristics of simple realization and simple hardware structure. The infrared cameras are integrated on a plurality of electronic devices, so that the acquisition of the visual distance and/or the visual angle can be completed by using the existing devices, the effective utilization rate of the existing devices is improved, and the hardware cost is reduced.

It is worth noting that: the information processing method described in this embodiment is a further improvement on the basis of the technical solution provided in any of the foregoing embodiments. For example, in the information processing method according to this embodiment, the visual condition information of the user may also be determined through output of the vision test information and acquisition of user feedback information, or the visual condition information of the user may also be acquired through acquisition of the user identification feature and through query. In short, the information processing method according to the present embodiment can be combined with any one of the technical solutions described in the foregoing embodiments to obtain a further technical solution, in terms of the technique that the technical solutions disclosed in the foregoing embodiments do not contradict each other.
