The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

The following describes the interaction method, apparatus, and wearable device based on atmospheric optical communication according to the embodiments of the present invention with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart of an interaction method based on atmospheric optical communication provided by an embodiment of the present invention.

As shown in Figure 1, the method includes the following steps:

Step 101, the wearable device uses an optical transceiver to send out signal light carrying the first handshake information.

In this embodiment of the present invention, the wearable device is, for example, a virtual reality VR head-mounted device, and the wearable device includes an optical transceiver for atmospheric optical communication. As a possible implementation, the optical transceiver includes an infrared transmitter and an infrared receiver. It realizes the direct interaction of information between wearable devices by emitting and receiving infrared signal light.

Specifically, the wearable device uses an optical transceiver to send out signal light that carries the first handshake information, where the first handshake information includes the relevant protocol information for establishing information interaction between the wearable device and the external device, so that the external device receives the transmission from the wearable device. After receiving the first handshake information, determine whether to establish information interaction with the wearable device based on the first handshake information.

Step 102, the wearable device adjusts the optical axis of the optical transceiver according to the detected viewing angle of the human eye, so that the adjusted optical axis matches the viewing angle of the human eye.

In the embodiment of the present invention, the wearable device may further be provided with a human eye eye tracking device, which is used to track and locate the position of the human eye and detect the human eye angle, that is, the observation angle of the human eye, and the wearable device detects the refresh rate of the human eye angle of view. Very high, for example, the wearable device can detect the human eye angle of view at a refresh rate of 120HZ, so that the detected human eye angle of view has high accuracy and real-time performance. Specifically, the human eyeball can reflect invisible light, thereby forming a reflection point on the eyeball. The wavelength that the human eye can perceive is 380nm-780nm. , the less harmful infrared light source, as a possible implementation method, the transmitting module in the human eye tracking device emits infrared rays, and after being reflected by the reflection module, the infrared rays are reflected into the human eyeballs, and the human eyeballs will respond to the received The infrared rays are reflected, and then, the imaging module collects the infrared rays reflected by the human eyeballs, uses the infrared rays to image the human eyeballs, identifies the user's eyeballs from the eyeball imaging, and detects the gaze direction of the eyeballs, that is, detects the human eye angle of view. Among them, when the human eye is concentrating, the angle of the viewing angle of the human eye is generally a fixed angle value, such as 20 degrees-30 degrees.

The optical axis of the optical transceiver can be adjusted. In this embodiment, the optical axis of the optical transceiver is adjusted according to the detected viewing angle of the human eye. That is, when the wearable device detects the human eye viewing angle, the wearable device According to the detected viewing angle of the human eye, the optical axis of the optical transceiver is adjusted so that the adjusted optical axis of the optical transceiver matches the viewing angle of the human eye, that is, the directionality of the wearable device and the viewing angle of the human eye are synchronized. In order to realize that when the viewing angles of the two wearable devices are opposite, the optical transceivers provided on the two wearable devices can transmit information.

As shown in Figure 2, the figure shows that the optical axis of the wearable device can be adjusted to make the adjusted optical axis match the viewing angle of the human eye, for example, wearable device A, external devices B and C in Figure 2, The transceiver angle corresponding to the optical axis of the optical transceiver, as shown by the solid line in FIG. 2 , and the angle of the viewing angle of the human eye, as shown by the dotted line in FIG. 2 , match each other.

It should be noted that the external devices B and C may also be wearable devices.

Step 103, in the process of adjusting the optical axis, the wearable device uses an optical transceiver to receive the signal light sent by the external device.

Specifically, in the process of adjusting the optical axis, the wearable device adopts an optical transceiver to receive the signal light emitted by the external device, wherein the external device, for example, can be another wearable device, and according to the information carried in the received signal light, Determine whether the external device needs to interact with the wearable device.

As shown in Figure 2, the optical transceiver of wearable device A will receive the signal light from external devices B and C. In one scenario, since the viewing angles of the human eyes detected by wearable device A and external device B are matched, then It means that the optical axis of the optical transceiver of wearable device A matches the optical axis of the optical transceiver of external device B, that is to say, the signal light emitted by wearable device A can be received by the optical transceiver of external device B, while the optical axis of the optical transceiver of external device B is matched. The information number sent by the optical transceiver of the external device B can also be received by the wearable device A, that is, information interaction based on the optical transceiver can be realized. In another scenario, as shown in FIG. 2 , the optical axes of the optical transceivers of the wearable device A and the external device C do not match, that is, the optical axes of the wearable device A and the external device C do not match. Signal light cannot be transmitted, nor can information exchange between wearable device A and external device C be realized.

Step 104, when the signal light received by the optical transceiver carries the first handshake information, the wearable device interacts with the external device through the optical transceiver.

Specifically, when the signal light received by the optical transceiver of the wearable device carries the first handshake information, it means that the external device needs to perform information interaction with the wearable device, for example, to realize business card exchange or video synchronization or sharing through interaction Wait. Then the wearable device detects the user's operation behavior. If the user's operation behavior belongs to the set behavior, the wearable device queries the corresponding relationship between the set behavior and the interaction information to determine the target interaction information corresponding to the user's operation behavior. Send the signal light carrying the target interaction information to the external device to realize the direct information interaction between the wearable device and the external device, which improves the efficiency of information interaction and improves the fun. For example, the wearable device detects that the user has blinked twice Eyes, by querying the set behavior, it is determined that the target interaction information corresponding to the user's blinking operation behavior is the user's business card, and the wearable device and the external device interact with the user's business card through the optical transceiver.

It should be noted that, after the external device receives the signal light of the first handshake information sent by the optical transceiver of the wearable device, if the external device needs to interact, the external device controls its own optical transceiver to respond to the received signal. The first handshake information is sent, and a preset duration is sent to ensure that the wearable device can receive the first handshake information, so as to establish information interaction between the wearable device and the external device.

It should be understood that the optical transceiver in the embodiment of the present invention realizes atmospheric optical communication by sending out signal light carrying handshake information, and compared with the atmospheric optical communication (Light Fidelity, LiFi) in the prior art, this In the embodiment of the invention, the direct interaction of information is realized by performing atmospheric optical communication through the optical transceiver, and there is no need for additional optical devices such as light bulbs for transmission, which is less affected by external factors, and improves the transmission efficiency. Connect with the router to reduce the cost of transmission.

In the interaction method of atmospheric optical communication according to the embodiment of the present invention, the wearable device uses an optical transceiver to send out signal light carrying the first handshake information, and adjusts the optical axis of the optical transceiver according to the detected viewing angle of the human eye, so that after the adjustment, the optical axis of the optical transceiver is adjusted. The optical axis matches the viewing angle of the human eye, and during the adjustment of the optical axis, the optical transceiver is used to receive the signal light sent by the external device. When the signal light received by the optical transceiver carries the first handshake information, the wearable device passes the light The transceiver interacts with external devices. By adjusting the optical axis of the optical transceiver of the wearable device to match the viewing angle of the human eye, and realizing optical communication based on the optical transceiver, it realizes direct information interaction between multiple wearable devices and fast data speed at close range. Sharing, high interaction efficiency, and at the same time improving the fun of interaction.

In the previous embodiment, it is explained that the target interaction information that needs to be interacted can be determined by detecting the user's operation behavior. The wearable device needs to send the signal light carrying the target interaction information to the external device through the optical transceiver. To this end, this embodiment provides another possible implementation of the interaction method based on atmospheric optical communication. FIG. 3 is an embodiment of the present invention. A schematic flowchart of another interaction method based on atmospheric optical communication is provided.

As shown in FIG. 3, based on the previous embodiment, step 104 may further include the following sub-steps:

Step 301, the wearable device detects the user's operation behavior.

As a possible implementation, it is possible to track the user's eyeballs to determine the change of the user's gaze point, and detect the user's operation behavior according to the change of the user's gaze point. When the position changes to the vertical position, it is determined that the user's operation behavior is a nodding operation. In another scenario, if the user's eyeballs are tracked to determine that the user's gaze point disappears and then reappears, it is determined that the user's operation behavior is an eye-blink operation.

As another possible implementation manner, a gyroscope can also be set on the wearable device, and by detecting the angle change of the gyroscope, the user operation performed by the user, such as a nodding operation, a shaking head operation, etc., can be determined.

As another possible implementation manner, a camera device provided on the wearable device can also collect user images, perform feature analysis according to the user images, and determine user operations performed by the user, such as blinking, nodding, or shaking his head.

Step 302, if the user operation behavior belongs to the set behavior, the wearable device queries the corresponding relationship between the set behavior and the interaction information to determine the target interaction information corresponding to the user operation behavior.

Specifically, the detected user operation behavior is compared with the preset set behavior. If the user operation behavior belongs to the set behavior, the wearable device further queries the corresponding relationship between the set behavior and the interaction information, wherein, The corresponding relationship between the set behavior and the interaction information may be predetermined, and the target interaction information corresponding to the user operation behavior is determined. For example, if the user's operation behavior is a nodding operation, the corresponding target interaction information is determined by query as video sharing.

Step 303 , the wearable device receives the signal light carrying the time information through the optical transceiver, where the time information is used to indicate the time when the external device detects the user's operation behavior.

Specifically, the wearable device receives and carries external devices through the optical transceiver

Step 304, compare and determine that the time when the external device detects the user's operation behavior is later than the time when the wearable device detects the user's operation behavior.

Step 305, the wearable device sends the signal light carrying the target interaction information to the external device through the optical transceiver.

In this embodiment of the present invention, after the target interaction information corresponding to the user's operation behavior is determined, it is further possible to determine that the external device detects the user's operation behavior by comparing the time when the wearable device detects the user's operation behavior and the time when the external device detects the user's operation behavior. The time of the user's operation behavior is later than the time when the wearable device detects the user's operation behavior, so the wearable device sends the signal light carrying the target interaction information to the external device through the optical transceiver to realize the interaction of information, and at the same time, the signal light is used to exchange information. The transmission of information improves the efficiency of information interaction and the fun of interaction.

For example, if the user's operation behavior is a nodding operation, the corresponding target interaction information is determined by query as video sharing. At the same time, it is determined through comparison that the user's nodding operation detected by the wearable device is earlier than the user's nodding operation detected by the external device, then The wearable device directly sends the video information to the external device through the signal light carrying the video information, realizing the interactive sharing of the video information. At the same time, the direct transmission of the interactive information through the signal light improves the efficiency of the information interaction and the fun of the interaction. .

In the interaction method based on atmospheric optical communication according to the embodiment of the present invention, after it is determined that the wearable device needs to exchange information with the external device through the optical transceiver, the user's operation behavior is further detected to determine the target information that needs to be interacted, and the comparison Whether the wearable device detects the user's operation time is earlier than the external device detects the user's operation time, to determine whether the wearable device sends the signal light carrying the target interaction information to the external device through the optical transceiver, so as to realize the fast and direct interaction of information, and Improve the fun of interaction.

In the previous embodiment, it is explained that the target interaction information that needs to be interacted can be determined by detecting the user's operation behavior. The device sends the signal light carrying the target interaction information to the external device through the optical transceiver. To this end, this embodiment provides another possible implementation of the interaction method based on atmospheric optical communication. FIG. 4 is provided by the embodiment of the present invention. A schematic flowchart of another interactive method based on atmospheric optical communication.

As shown in FIG. 4, based on the previous embodiment, step 104 may further include the following sub-steps:

Step 401, the wearable device detects the user's operation behavior.

Step 402, if the user's operation behavior belongs to the set behavior, the wearable device queries the corresponding relationship between the set behavior and the interaction information to determine the target interaction information corresponding to the user's operation behavior.

Specifically, reference may be made to steps 301 to 302 in the previous embodiment, the principles are the same, and details are not repeated here.

Step 403, the wearable device receives the signal light carrying the operation information through the optical transceiver, wherein the operation information is used to instruct the external device to detect the user's operation behavior.

Step 404, compare to determine that the user operation behavior detected by the external device is the same as the user operation behavior detected by the wearable device.

Step 405, the wearable device sends the signal light carrying the target interaction information to the external device through the optical transceiver.

In this embodiment of the present invention, after the target interaction information corresponding to the user's operation behavior is determined, the user's operation behavior detected by the wearable device and the user's operation behavior detected by the external device may further be compared to determine the user's operation behavior detected by the external device. Whether the user operation behavior is the same as the user operation behavior detected by the wearable device. If the same, the wearable device sends the signal light carrying the target interaction information to the external device through the optical transceiver. At the same time, the external device can also send the wearable device through the optical transceiver. The signal light carrying the target interaction information is sent to realize the information interaction, and at the same time, the transmission of the interaction information through the signal light improves the efficiency of the information interaction and the interest of the interaction.

For example, if the user's operation behavior is an eye-blink operation, the corresponding target interaction information is determined by query as personal information. At the same time, it is determined by comparison that the user's eye-blink operation detected by the wearable device is the same as the user's eye-blink operation detected by the external device. Then the personal information is exchanged between the wearable device and the external device through the corresponding optical transceiver, which realizes the interactive sharing of personal information. At the same time, the direct transmission of personal information through signal light improves the efficiency of information interaction and improves the interaction. fun.

In the interaction method based on atmospheric optical communication according to the embodiment of the present invention, after it is determined that the wearable device needs to exchange information with the external device through the optical transceiver, the user's operation behavior is further detected to determine the target information that needs to be interacted, and the comparison Whether the user operation detected by the wearable device is the same as the user operation detected by the external device, determine whether the wearable device and the external device need to exchange information to achieve fast and direct interaction of interactive information, and improve the fun of the interaction .

Based on the above-mentioned embodiment, the embodiment of the present invention also proposes a possible implementation manner of the interaction method based on atmospheric optical communication. FIG. 5 is a schematic flowchart of another interaction method based on atmospheric optical communication provided by the embodiment of the present invention. , as shown in Figure 5, the method includes the following steps:

Step 501, the wearable device uses an optical transceiver to send out signal light that carries the first handshake information.

Step 502, the wearable device adjusts the optical axis of the optical transceiver according to the detected viewing angle of the human eye, so that the adjusted optical axis matches the viewing angle of the human eye.

Step 503, in the process of adjusting the optical axis, the wearable device uses the optical transceiver to receive the signal light sent by the external device.

Specifically, steps 101 to 103 in the foregoing embodiment may be referred to, and the principles are the same, which will not be repeated here.

Step 504 , determine whether the signal light received by the optical transceiver of the wearable device carries the first handshake information, if yes, go to step 505 , if not, go to step 506 .

Specifically, if the signal light received by the optical transceiver of the wearable device carries the first handshake information, execute step 505; otherwise, if the signal light received by the optical transceiver of the wearable device carries the second handshake information, execute Step 506.

Step 505, the wearable device interacts with the external device through the optical transceiver.

Specifically, reference may be made to step 104 in the embodiment of FIG. 1 , the principle is the same, and details are not repeated here.

Step 506, the optical transceiver is controlled to emit the signal light carrying the second handshake information, and after the set time period is reached, the optical transceiver is controlled to re-transmit the signal light carrying the first handshake information.

The second handshake information refers to the information sent by other external devices, which is to be different from the first handshake information sent by the wearable device in this embodiment.

Specifically, if the signal light received by the optical transceiver carries the second handshake information, it means that an external device needs to exchange information with the wearable device, and the wearable device controls the optical transceiver to send out the signal light that carries the second handshake information, And reach the set duration, by sending the signal light carrying the second handshake information multiple times to ensure that the external device can receive the signal light carrying the second handshake information sent by the wearable device, if the preset duration is reached, the wearable device does not communicate with the external device The device interacts. For example, if the wearable device does not detect the user operation, or the user operation does not belong to the set behavior, the wearable device does not interact with the external device, but controls the optical transceiver to re-transmit the signal light carrying the first handshake information.

In the interaction method based on atmospheric optical communication according to the embodiment of the present invention, in the process of adjusting the optical axis of the optical transceiver of the wearable device, after the wearable device uses the optical transceiver to receive the signal light sent by the external device, if the optical transceiver receives When the signal light carries the second handshake information, the optical transceiver is controlled to emit the signal light carrying the second handshake information, and after the set time period is reached, the optical transceiver is controlled to re-send the signal light carrying the first handshake information.
