In order to illustrate the technical solution of the present application, the following description is made by specific examples.
Augmented reality (Augmented Reality, AR) is a technology of simulating virtual information (virtual display content) through a scientific technology, and then overlaying the virtual information (virtual display content) to the real world (real display content) to be perceived by human senses, so that the sense experience of super reality is achieved. However, in the current augmented reality technology, the virtual display content is simply superimposed in the real world, which has a problem of a single display mode, and the requirements of users in different scenes cannot be met.
For example, in practical applications, a user may have a situation where the user feels uncomfortable with the virtual display content superimposed on the live-action display content and wishes to weaken the display effect of the virtual display content superimposed on the live-action display content, or a situation where the virtual display content superimposed on the live-action display content is very thick and wishes to enhance the display effect of the virtual display content superimposed on the live-action display content.
Based on this, the embodiments of the present application provide an augmented reality display method, apparatus, terminal, and computer readable storage medium, which can solve the technical problem of single display mode of virtual display content.
Fig. 1 shows a schematic implementation flow chart of an augmented reality display method according to an embodiment of the present application, where the method is applied to a terminal and may be executed by an augmented reality display device configured on the terminal. The terminal may be an augmented reality device such as AR glasses, which may implement an augmented reality function. The above-described augmented reality display method may include steps 101 to 103.
Step 101, acquiring signal parameters of biological signals.
The biological signal may include a biological signal acquired when the target object views the augmented reality display content.
When the target object uses the augmented reality function of the terminal having the augmented reality function, the real-scene display content and the virtual display content superimposed on the real-scene display content output by the terminal device can be seen through the terminal device, and therefore, the display content of the target object for viewing the augmented reality can include the real-scene display content and the virtual display content superimposed on the real-scene display content.
At present, the virtual display content is a display screen projected on a projection surface with a certain fixed distance through a terminal, so that discomfort such as dizziness and fatigue may occur when a target object views the virtual display content for a long time, and when the plot of the virtual display content is a display content which is more frightened and liable to fear the target object, discomfort of the target object may also occur, and meanwhile, the plot of the virtual display content is more falling and fluctuant, resonance of the target object is liable to occur, so that the target object has higher probability of being highly productive to the virtual display content.
Therefore, in order to know in real time whether the target object has such discomfort, whether the target object is in a state where rest is required or whether the target object is in a state where it is more comfortable is determined, it is necessary to perform judgment by acquiring in real time the signal parameters of the bio-signal of the target object when viewing the display content of augmented reality.
Wherein, the signal parameters of the biological signal may include: parameters such as signal parameters of brain nerve signals of a target object, eye opening and closing degree parameters, heart rate parameters, blood pressure parameters, pupil size and the like.
The eye opening and closing degree parameter includes a blink frequency of the target object and a change rate of an eye opening area of the target object; the change rate of the eye opening area of the target object is obtained by subtracting the initial eye opening area of the target object from the real-time eye opening area of the target object and dividing the initial eye opening area of the target object. The initial eye opening area is the eye opening area when the target object just begins to watch the display content of the augmented reality.
In some embodiments of the present application, if the signal parameter of the biological signal is a cranial nerve signal parameter of the target object, a cranial nerve signal sensor provided on the terminal may be used to obtain a cranial nerve signal of the target object when the augmented reality display content in the viewing field of view is viewed.
The signal parameters of the cranial nerve signal may include signal parameters such as frequency, phase, and signal intensity of the cranial nerve signal.
Specifically, the above-mentioned cranial nerve signal sensor provided on the terminal may include a cranial nerve signal sensor for contact detection and/or a cranial nerve signal sensor for non-contact detection; for example, the above-mentioned cranial nerve signal sensor provided on the terminal device may be a micro current sensor capable of acquiring a cranial nerve signal of a target object when the augmented reality display content of the target object is viewed in a visual field by detecting a micro current change generated when the brain activity is detected by touching the scalp of the target object; for another example, the sensor provided on the terminal device may be a micro-magnetic sensor, and the micro-magnetic sensor may detect a magnetic field change generated by brain current without touching the target object, so as to obtain a cranial nerve signal when the target object views the augmented reality display content in the field of view.
As shown in fig. 2, a first structural schematic diagram of a terminal provided in this embodiment of the present application, in some embodiments of the present application, the terminal may include sensors 21, 22, 23 respectively disposed at the front, side and rear of the terminal, and may be used to detect cranial nerve signals of a plurality of parts such as the forehead, the near-ear and the hindbrain of a user.
In addition, in some embodiments of the present application, the terminal may further include a micro display DLP, which may include a driving power chip, a data control chip, a digital micromirror DMD (Digital Micro Mirror Device), a light source, an optical system, and the like. The driving power chip and the data control chip control the digital micro mirror and the light source to work cooperatively, and the digital micro mirror is a semiconductor switch reflection display device with high resolution. The light emitted by the light source passes through the optical system and reaches the digital micro-mirror, and the digital micro-mirror reflects the light to form display content.
And 102, calculating target display parameters of virtual display contents in the display contents according to the signal parameters of the biological signals.
In this embodiment of the present application, before calculating the target display parameters of the virtual display content in the display content according to the signal parameters of the biological signals, a large number of experiments may be performed to obtain target display parameters corresponding to the signal parameters of different biological signals; or obtaining target display parameters corresponding to the signal parameters of different biological signals according to practical experience in advance.
And step 103, adjusting the display parameters of the virtual display content to target display parameters.
In this embodiment of the present application, the adjusting the display parameter of the virtual display content to the target display parameter may include: according to the signal parameters of the biological signals of the user, the display effect of the virtual display content superimposed on the live-action display content is weakened, so that the attention of human eyes is transferred to the live-action display content, and the discomfort of the target object brought by the virtual display content is reduced; or the display effect of the virtual display content overlapped on the live-action display content is enhanced, so that the target object obtains a stronger visual effect, and the display requirement of the target object on the virtual display content under different scenes is met.
In the embodiment of the application, the signal parameters of the biological signals of the target object when the display content of the augmented reality is watched are obtained, and then the target display parameters of the virtual display content in the display content are calculated according to the signal parameters of the biological signals; the display parameters of the virtual display content can be adjusted according to the signal parameters of the biological signals so as to meet the requirements of the target object in different viewing states, and the technical problem of single display mode of the virtual display content is solved.
For example, the signal parameter of the above-mentioned biological signal may reflect an emotional state of the target object when viewing the display content of the augmented reality, and thus, the target display parameter may be a display parameter of the target object in a virtual display content corresponding to different emotional states; according to the method and the device, the display parameters of the virtual display content are adjusted to the target display parameters, so that the display parameters of the virtual display content can be adjusted according to the emotion state of the target object, the diversification of the display mode of the virtual display content is realized, and different requirements of the target object on comfort level or visual effect and the like are met.
Specifically, as shown in fig. 3, in some embodiments of the present application, in the step 102, calculating the target display parameter of the virtual display content in the display content according to the signal parameter of the biological signal may include: steps 301 to 302.
Step 301, judging whether the target object is in a state requiring rest according to the signal parameters of the biological signals.
In this embodiment of the present application, the state requiring rest may include a state requiring rest caused by fear of the target object, a state requiring rest caused by fatigue of the target object, a state requiring rest caused by stress of the target object, and a state requiring rest caused by other reasons of the target object.
Specifically, before judging whether the target object is in a state requiring rest according to the signal parameters of the biological signal, the terminal can acquire the state requiring rest of the target object caused by fear, the state requiring rest of the target object caused by fatigue, or the reference signal parameters of the biological signal corresponding to the state requiring rest of the target object caused by stress, so that when judging whether the target object is in the state requiring rest according to the signal parameters of the biological signal, the terminal can confirm whether the target object is in the state requiring rest by comparing the signal parameters of the biological signal with the reference signal parameters.
For example, a large number of experiments can be performed to obtain reference signal parameters such as frequency, phase and signal intensity of a cranial nerve signal of different target objects in a state where rest is required caused by different reasons, then obtain signal parameters of the cranial nerve signal of the target objects when the augmented reality device is used for watching the virtual display content and the real display content of the augmented reality, and compare the signal parameters of the cranial nerve signal with the reference signal parameters to obtain whether the target objects are in the state where rest is required when the augmented reality device is used for watching the virtual display content and the real display content of the augmented reality.
Step 302, if the target object is in a state requiring rest, one or more target display parameters of target brightness, target chromaticity, target display area and target display position of the virtual display content corresponding to the state requiring rest are obtained.
In this embodiment of the present invention, the above-mentioned target display parameter corresponding to the state requiring rest is a display parameter for weakening the display effect of the virtual display content, improving the virtual display content of the target object state, for example, for improving the state requiring rest caused by fear of the target object, improving the state requiring rest caused by fatigue of the target object, improving the state requiring rest caused by tension of the target object, and improving the virtual display content of the state requiring rest caused by other reasons of the target object, so that the target object may be converted from the state requiring rest to the state not requiring rest.
Likewise, the above-mentioned acquisition of the target display parameters corresponding to the state requiring rest can still be obtained by performing a large number of experiments.
For example, a large number of experiments can be performed to obtain display parameters of virtual display contents adopted when different target objects are in a state of needing to rest caused by different reasons and are converted into a state of not needing to rest, statistics and analysis are performed on a large amount of obtained data, and the display parameters of the virtual display contents with the highest success rate are selected to be respectively used as target display parameters corresponding to the state of the different target objects needing to rest caused by different reasons.
In some embodiments of the present application, the specific values of the target display parameters, such as the target brightness, the target chromaticity, the target display area, and the target display position, of the virtual display content corresponding to the state requiring rest may be set according to actual experience.
For example, the target luminance may be set to 0 or other luminance value capable of reducing the attractive force to the target object to a set degree; and/or setting the target chromaticity to a cool tone capable of alleviating fatigue of the target object; and/or setting the target display area to 0 or other display area capable of reducing the attractive force to the target object to a set degree; and/or setting the target display position of the virtual display content to be a position deviating from the center of the visual field of the target object, so that the virtual display content cannot attract the target object, and the target object is allowed to rest.
Accordingly, in some embodiments of the present application, the adjusting the display parameter of the virtual display content to the target display parameter may include: and adjusting the brightness of the virtual display content in the display content to be the target brightness corresponding to the state needing rest, and/or adjusting the chromaticity of the virtual display content in the display content to be the target chromaticity corresponding to the state needing rest, and/or adjusting the display area of the virtual display content in the display content to be the target display area corresponding to the state needing rest, and/or adjusting the display position of the virtual display content in the display content to be the target display position corresponding to the state needing rest.
For example, when the target brightness of the virtual display content in the display content calculated according to the signal parameters of the biological signal is lower than the brightness of the virtual display content in the display content of the current augmented reality, the brightness of the virtual display content can be adjusted to be the target brightness, and the brightness of the virtual display content overlapped on the real display content is reduced, so that the target object is at rest; for another example, the target chromaticity of the virtual display content in the display content calculated according to the signal parameters of the biological signal is higher than the chromaticity of the virtual display content in the display content of the current augmented reality, so that when the chromaticity of the virtual display content is adjusted to the target chromaticity, the virtual display content superimposed on the real display content tends to be the cold tone, and the target object is at rest; for another example, the target display area of the virtual display content in the display content calculated according to the signal parameters of the biological signal is smaller than the display area of the virtual display content in the display content of the current augmented reality, so that when the display area of the virtual display content is adjusted to be the target display area, the virtual display content overlapped on the real scene display content is reduced, and the target object is at rest; for another example, the target display position of the virtual display content in the display content calculated according to the signal parameter of the biological signal is further away from the center of the visual field range than the display position of the virtual display content in the display content of the current augmented reality, so that when the display position of the virtual display content is adjusted to the target display position, the attention of the target object is focused on the real display content, and rest is obtained.
In the embodiment described in fig. 3, the acquiring the target luminance and the target chromaticity corresponding to the state requiring rest may include: and acquiring the brightness and the chromaticity of the real scene display content in the display content, and calculating the target brightness and the target chromaticity corresponding to the state needing rest according to the brightness and the chromaticity of the real scene display content.
The brightness and the chromaticity of the live-action display content in the display content can be acquired through a camera arranged on the augmented reality terminal equipment.
Specifically, the target luminance calculated when the luminance of the live-action display content is high is higher than the target luminance calculated when the luminance of the live-action display content is low, that is, in order to divert the human eye attention of the target object to the live-action display content as well, the degree of lowering the luminance of the virtual display content when the luminance of the live-action display content is high is smaller than the degree of lowering the luminance of the virtual display content when the luminance of the live-action display content is low.
Similarly, the target tone of the virtual display content in the display content calculated when the tone of the live-action display content is warm is warmer than the target tone of the virtual display content in the display content calculated when the brightness of the live-action display content is colder.
In some embodiments of the present application, after the step 301, the method may further include: and if the target object is in the state requiring rest, converting virtual display content in the display content according to the signal parameters of the biological signals.
That is, in addition to the aforementioned change of the display parameters of the virtual display content according to the signal parameters of the biological signal, the present application further achieves the effect of resting the target object by changing the virtual display content superimposed on the live-action display content according to the signal parameters of the biological signal.
Specifically, as shown in fig. 4, the transforming the virtual display content in the display content according to the signal parameter of the biological signal may include: steps 401 to 402.
Step 401, uploading signal parameters of the biological signals to a cloud server.
After receiving the signal parameters of the biological signal, the cloud server may recommend virtual display content corresponding to the signal parameters of the biological signal to the augmented reality terminal device.
For example, if the cloud server receives the signal parameter of the biological signal corresponding to the state that the target object is in need of rest, the virtual display content that enables the target object to get rest may be recommended to the augmented reality terminal device.
It should be noted that, the virtual display content recommended by the cloud server according to the signal parameters of the biological signal may include one or more virtual display contents.
And step 402, receiving and displaying virtual display contents recommended by the cloud server according to the signal parameters of the biological signals.
When the virtual display content recommended by the cloud server according to the signal parameters of the biological signal is a plurality of virtual display contents, after receiving and displaying the virtual display content recommended by the cloud server according to the signal parameters of the biological signal, the method may further include: and acquiring a virtual display content selection operation, and displaying virtual display content corresponding to the virtual display content selection operation.
In the embodiment of the application, the virtual display content in the display content is changed according to the signal parameters of the biological signals, so that the terminal equipment can change the virtual display content simultaneously according to the display parameters of the virtual display content, the diversification of the display mode of the virtual display content is further realized, and different requirements of a target object on comfort level, visual effect and the like are met.
In some embodiments of the present application, after adjusting the display parameter of the virtual display content to the target display parameter, the method may further include: monitoring whether the rest time length of the target object is longer than the preset time length, and if the rest time length of the target object is longer than the preset time length, restoring the display parameters of the virtual display content to the display parameters before adjustment.
Wherein, the preset time period can be set according to practical experience.
In the embodiment of the application, if the rest time of the target object is longer than the preset time, the target object is fully resting, and the augmented reality function can be reused, at this time, the terminal device can restore the display parameters of the virtual display content to the display parameters before adjustment, so that the target object experiences the immersion experience brought by the augmented reality again.
In some embodiments of the present application, as shown in fig. 5, the calculating, in step 102, the target display parameter of the virtual display content in the display content according to the signal parameter of the biological signal may further include: step 501 to step 502.
Step 501, judging whether the target object is in a better state according to the signal parameters of the biological signals.
In this embodiment, the above-mentioned state of being in a better state may include a state in which the attention of the target object is highly concentrated, or a state in which the target object is relatively excited and pleasant.
Step 502, if the target object is in a better state, obtaining one or more target display parameters of target brightness, target chromaticity, target display area and target display position of the virtual display content corresponding to the better state.
In this embodiment of the present invention, the target display parameter corresponding to the well-developed state is a display parameter for enhancing a display effect of the virtual display content and improving a visual effect of the target object watching the virtual display content.
Specifically, the specific implementation manner of determining whether the target object is in the state of good making and obtaining the target display parameter corresponding to the state of good making may refer to the descriptions of determining whether the target object is in the state of needing rest and obtaining the target display parameter corresponding to the state of needing rest in steps 301 to 302, which are not repeated herein.
Correspondingly, the adjusting the display parameter of the virtual display content to the target display parameter may include: and adjusting the brightness of the virtual display content in the display content to be the target brightness corresponding to the good state, and/or adjusting the chromaticity of the virtual display content in the display content to be the target chromaticity corresponding to the good state, and/or adjusting the display area of the virtual display content in the display content to be the target display area corresponding to the good state, and/or adjusting the display position of the virtual display content in the display content to be the target display position corresponding to the good state.
In practical applications, the target object may need to adjust the display parameters of the virtual display content by itself, for example, after the display parameters of the virtual display content are adjusted to the target display parameters, the target object may want to restore to the display parameters before adjustment; for example, after the above-described restoration of the display parameters of the virtual display content to the display parameters before adjustment, the target object may wish to continue restoration of the display parameters of the virtual display content to the display parameters after adjustment.
Thus, in other embodiments of the present application, as shown in fig. 6, the above-mentioned augmented reality display method may further include: steps 601 to 602.
Step 601, a display mode selection instruction is received.
Wherein the display mode selection instruction is triggered by a button provided by the terminal device, and different display mode selection instructions correspond to different display parameters.
Step 602, adjusting the display parameters of the virtual display content to the display parameters corresponding to the display mode selection instruction.
According to the embodiment of the application, after the target object triggers the display mode selection instruction according to the needs of the target object, the terminal equipment adjusts the display parameters of the virtual display content to the display parameters corresponding to the display mode selection instruction, so that the display parameters of the virtual display content accord with the current needs of the target object, and misoperation of adjusting the display parameters is avoided.
