The following describes an interaction method, an interaction device and wearable equipment based on atmospheric optical communication according to an embodiment of the invention with reference to the drawings.
Fig. 1 is a schematic flowchart of an interaction method based on atmospheric optical communication according to an embodiment of the present invention.
As shown in fig. 1, the method comprises the steps of:
In the embodiment of the invention, the wearable device is, for example, a Virtual Reality (VR) head-mounted device, the wearable device comprises an optical transceiver for atmospheric optical communication, as a possible implementation manner, the optical transceiver comprises an infrared transmitter and an infrared receiver, and information direct interaction between the wearable devices is realized by transmitting and receiving infrared signal light.
Specifically, the wearable device sends signal light carrying first handshake information by using an optical transceiver, wherein the first handshake information includes protocol information related to information interaction established between the wearable device and the external device, so that the external device determines whether to establish information interaction with the wearable device based on the first handshake information after receiving the first handshake information sent by the wearable device.
In the embodiment of the invention, the wearable device can also be provided with a human eye eyeball tracking device which is used for tracking and positioning the position of the human eye eyeball and detecting to obtain the human eye visual angle, namely the observation angle of the human eye, and the refresh rate of the wearable device for detecting the human eye visual angle is very high, for example, the wearable device can detect the human eye visual angle at the refresh rate of 120HZ, so that the accuracy and the real-time performance of the detected human eye visual angle are very high. Specifically, the human eye eyeball can reflect invisible light, so that a reflection point is formed on the eyeball, the wavelength which can be perceived by the human eye is 380 nm-780 nm, in order to not influence the normal watching of a user by using wearable equipment, an infrared light source which is low in human eye sensitivity and less in harm can be selected, as a possible implementation mode, an emission module in the human eye eyeball tracking device emits infrared rays, the infrared rays are reflected into the human eye eyeball after being reflected by the reflection module, the human eye eyeball can reflect the received infrared rays, furthermore, the imaging module collects the infrared rays reflected by the human eye eyeball, the human eye eyeball is imaged by the infrared rays, the eyeball of the user is identified from the eyeball imaging, the eyeball watching direction is detected, and the human eye viewing angle is detected. Wherein, when the human eye is focusing on attention, the angle of the visual angle of the human eye is generally a fixed angle value, for example, 20 degrees to 30 degrees.
Wherein, the optical axis of optical transceiver can be adjusted, the optical axis of optical transceiver in this embodiment is adjusted according to the people's eye visual angle that detects, that is to say, after wearing equipment detects people's eye visual angle, wearing equipment then according to the people's eye visual angle that detects, the optical axis of adjustment optical transceiver, so that the optical axis and the people's eye visual angle of optical transceiver after adjusting match, the synchronization of wearing equipment's directionality and people's eye visual angle directionality has been realized promptly, when realizing two wearing equipment visual angles and being relative, the optical transceiver that sets up on two wearing equipment can carry out the transmission of information.
As shown in fig. 2, it is shown that the optical axis of the wearable device can be adjusted to match the adjusted optical axis with the viewing angle of the human eye, for example, as shown in fig. 2, wearable device a, external devices B and C, wherein the transceiving angle corresponding to the optical axis of the optical transceiver is shown as a solid line in fig. 2, and the angle of the viewing angle of the human eye is shown as a dotted line in fig. 2.
The external devices B and C may be wearable devices.
Specifically, in the optical axis adjustment process, the wearable device receives signal light emitted by an external device through an optical transceiver, where the external device may be another wearable device, for example, and determines whether the external device needs to interact with the wearable device according to information carried in the received signal light.
As shown in fig. 2, the optical transceiver of the wearable device a receives the signal light emitted by the external devices B and C, and in a scenario, since the angles of view of human eyes detected by the wearable device a and the external device B are matched, it is indicated that the optical axis of the optical transceiver of the wearable device a and the optical axis of the optical transceiver of the external device B are matched, that is, the signal light emitted by the wearable device a can be received by the optical transceiver of the external device B, and the information number emitted 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 transceivers can be implemented. In another scenario, as shown in fig. 2, optical axes of the optical transceiver of the wearable device a and the optical transceiver of the external device C are not matched, that is, signal light cannot be transmitted between the optical transceiver of the wearable device a and the optical transceiver of the external device C, and information interaction between the wearable device a and the external device C cannot be achieved.
And 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 indicates that the external device needs to perform information interaction with the wearable device, for example, business card exchange or video synchronization or sharing is achieved through interaction. The wearable device detects the user operation behavior, if the user operation behavior belongs to the set behavior, the wearable device inquires the corresponding relation between the set behavior and the interaction information to determine target interaction information corresponding to the user operation behavior, the wearable device sends signal light carrying the target interaction information to the external device through the optical transceiver to realize direct information interaction between the wearable device and the external device, the efficiency of information interaction is improved, and interestingness is also improved.
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 with the wearable device, the external device controls the optical transceiver of the external device to send the received first handshake information, and sends a preset duration to ensure that the wearable device can receive the first handshake information, thereby implementing 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 implements 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, the optical transceiver in the embodiment of the present invention implements direct interaction of information by performing atmospheric optical communication through the optical transceiver, and does not need to additionally transmit through an optical device such as a bulb, which is less affected by external factors, thereby improving transmission efficiency, and meanwhile, during transmission, the optical transceiver does not need to be connected with a router, which reduces transmission cost.
In the interaction method for atmospheric optical communication in the embodiment of the invention, the wearable device sends out the signal light carrying the first handshake information by the optical transceiver, adjusts the optical axis of the optical transceiver according to the detected visual angle of human eyes, so that the adjusted optical axis is matched with the visual angle of human eyes, receives the signal light sent by the external device by the optical transceiver in the optical axis adjustment process, interacts with the external device by the wearable device through the optical transceiver when the signal light received by the optical transceiver carries the first handshake information, matches with the visual angle of human eyes by adjusting the optical axis of the optical transceiver of the wearable device, and realizes optical communication based on the optical transceiver, thereby realizing direct information interaction and short-distance data rapid sharing among a plurality of wearable devices, having high interaction efficiency, and improving the interest of interaction.
In the above embodiment, it is described that target interaction information that needs to be interacted may be determined by detecting an operation behavior of a user, and in an actual application, it may also be determined whether the wearable device needs to send signal light carrying the target interaction information to an external device through an optical transceiver by comparing the time when the operation behaviors of the wearable device and the external device are detected.
As shown in fig. 3, based on the previous embodiment, step 104 may further include the following sub-steps:
As a possible implementation manner, the change of the gaze point of the user can be determined by tracking the eyeballs of the user, the operation behavior of the user is detected according to the change of the gaze point of the user, and in a scene, if the change of the gaze point of the user from the horizontal position to the vertical position is determined by tracking the eyeballs of the user, the operation behavior of the user is determined to be nodding operation. In another scene, if the eyeball of the user is tracked to determine that the fixation point of the user disappears and then appears, the operation behavior of the user is determined to be blinking operation.
As another possible implementation manner, a gyroscope may be further disposed on the wearable device, and the user operation performed by the user, for example, a nodding operation, a shaking operation, and the like, is determined by detecting an angle change of the gyroscope.
As still another possible implementation manner, images of the user may be acquired through a camera device disposed on the wearable device, feature analysis may be performed according to the images of the user, and a user operation performed by the user, for example, a blinking operation, a head-shaking operation, or a head-shaking operation, may be determined.
Specifically, the detected user operation behavior is compared with a preset setting behavior, and if the user operation behavior belongs to the setting behavior, the wearable device further queries a corresponding relationship between the setting behavior and the interaction information, where the corresponding relationship between the setting behavior and the interaction information may be predetermined, and determines target interaction information corresponding to the user operation behavior. For example, if the operation behavior of the user is nodding operation, the corresponding target interaction information is determined to be video sharing through query.
Specifically, the wearable device receives the portable external device through the optical transceiver
And step 304, comparing to determine that the moment when the external device detects the user operation behavior is later than the moment when the wearable device detects the user operation behavior.
In the embodiment of the invention, after the target interaction information corresponding to the operation behavior of the user is determined, the time when the wearable device detects the operation behavior of the user and the time when the external device detects the operation behavior of the user can be further compared, and the time when the external device detects the operation behavior of the user is determined to be later than the time when the wearable device detects the operation behavior of the user, so that the wearable device sends the signal light carrying the target interaction information to the external device through the optical transceiver to realize information interaction, and meanwhile, the transmission of the interaction information through the signal light improves the efficiency of information interaction and the interest of the interaction.
For example, the operation behavior of the user is nodding operation, then confirm that the corresponding target mutual information is shared for the video through the inquiry, simultaneously, confirm that wearing equipment detects the operation that the user nods earlier than the nodding operation of the user that external equipment detected through comparing, then wearing equipment directly sends video information to external equipment through the signal light that carries video information, video information's mutual sharing has been realized, the efficiency of information interaction has been improved to the direct transmission of carrying out mutual information through signal light simultaneously, interactive interest has also been improved.
In the interaction method based on atmospheric optical communication of the embodiment of the invention, after the wearable device is determined to perform information interaction with the external device through the optical transceiver, the target information required to be interacted is further determined by detecting the operation behavior of the user, and whether the operation time of the user detected by the wearable device is earlier than the operation time of the user detected by the external device is determined by comparing, so that whether the wearable device sends the signal light carrying the target interaction information to the external device through the optical transceiver or not is determined, thereby realizing the rapid and direct interaction of the information and improving the interest of the interaction.
In the above embodiment, it is described that target interaction information that needs to be interacted may be determined by detecting an operation behavior of a user, and in an actual application, it may also be determined whether a wearable device needs to send a signal light carrying the target interaction information to an external device through an optical transceiver by comparing whether detected operation behaviors of the wearable device and the external device are the same.
As shown in fig. 4, based on the previous embodiment, step 104 may further include the following sub-steps:
Specifically, reference may be made to step 301 to step 302 in the previous embodiment, which have the same principle and are not described herein again.
In the embodiment of the invention, after the target interaction information corresponding to the operation behavior of the user is determined, whether the user operation behavior detected by the external device is the same as the user operation behavior detected by the wearable device or not can be further determined by comparing the user operation behavior detected by the wearable device with the user operation behavior detected by the external device, if so, the wearable device sends the signal light carrying the target interaction information to the external device through the optical transceiver, meanwhile, the external device can also send the signal light carrying the target interaction information to the wearable device through the optical transceiver, so that the information interaction is realized, meanwhile, the transmission of the interaction information through the signal light improves the efficiency of the information interaction, and the interestingness of the interaction is also improved.
For example, if the operation behavior of the user is blinking operation, the corresponding target interaction information is determined to be personal information through query, meanwhile, it is determined through comparison that the blinking operation of the user detected by the wearable device is the same as the blinking operation of the user detected by the external device, and then the wearable device and the external device exchange the personal information through the corresponding optical transceiver, so that interactive sharing of the personal information is realized, meanwhile, the information interaction efficiency is improved through direct transmission of the personal information through signal light, and the interaction interest is also improved.
According to the interaction method based on the atmospheric optical communication, after the fact that the wearable device needs to perform information interaction with the external device through the optical transceiver is determined, the target information needing to be interacted is further determined by detecting the operation behavior of the user, whether the user operation detected by the wearable device is the same as the user operation detected by the external device or not is determined by comparing whether the user operation detected by the wearable device and the user operation detected by the external device are the same, whether the information needs to be sent to each other or not is determined, so that the rapid and direct interaction of the interaction information is achieved, and the interestingness of the interaction is improved.
Based on the foregoing embodiments, the embodiments of the present invention further provide a possible implementation manner of an interaction method based on atmospheric optical communication, and fig. 5 is a schematic flow diagram of another interaction method based on atmospheric optical communication according to an embodiment of the present invention, as shown in fig. 5, the method includes the following steps:
Specifically, reference may be made to steps 101-103 in the above embodiments, which have the same principle and are not described herein again.
Specifically, if the signal light received by the optical transceiver of the wearable device carries the first handshake information, step 505 is executed, otherwise, if the signal light received by the optical transceiver of the wearable device carries the second handshake information, step 506 is executed.
In step 505, the wearable device interacts with an external device through the optical transceiver.
Specifically, reference may be made to step 104 in the embodiment of fig. 1, which has the same principle and is not described herein again.
The second handshake information is sent by other external devices, and is different from the first handshake information sent by the wearable device in this embodiment.
Specifically, when the signal light received by the optical transceiver carries second handshake information, it is indicated that an external device needs to perform information interaction with the wearable device, the wearable device controls the optical transceiver to send the signal light carrying the second handshake information, and a set time is reached, the signal light carrying the second handshake information is sent for multiple times, it is ensured that the external device can receive the signal light carrying the second handshake information sent by the wearable device, and if the preset time is reached, the wearable device does not interact with the external device, for example, the wearable device does not detect user operation, or the user operation does not belong to a set behavior, the wearable device does not interact with the external device, and the optical transceiver is controlled to send the signal light carrying the first handshake information again.
In the interaction method based on the atmospheric optical communication, in the optical axis adjustment process of the optical transceiver of the wearable device, after the wearable device receives the signal light sent by the external device by the optical transceiver, if the signal light received by the optical transceiver carries second handshake information, the optical transceiver is controlled to send the signal light carrying the second handshake information, until the set time length is reached, the optical transceiver is controlled to send the signal light carrying the first handshake information again, and the accuracy of information interaction between the wearable device and the external device is improved by sending the signal light containing the handshake information for multiple times within the set time length.
