The present disclosure relates to wearable monocular glasses, a combined binocular glasses system and control methods thereof.
Augmented Reality (AR) is a technique for calculating a position and an angle of a camera for photography and adding a corresponding image in real time. The goal of this technique is to show a virtual world overlapped with a real world at the same time on a screen and interactions can be performed. The augmented reality technology simulates and overlaps physical information (visual information, sound, taste, touch, etc.) in a certain time and space range in the real world by means of scientific technologies, such as computer technologies, and thus applies the virtual information to the real world.

An embodiment of the present disclosure provides wearable monocular glasses. As shown in
In the wearable monocular glasses according to the embodiments of the present disclosure, the optical imaging component 10 is configured to convert a virtual image signal inputted from the outside into a specific virtual image and project it onto a display surface, so that when wearing the wearable monocular glasses of the embodiments of the present disclosure, a user may see a complete virtual image through the display surface of the optical imaging component 10. Specific structures and connection relationships of the optical imaging component 10 in the embodiments of the present disclosure are not limited. Illustratively, the optical imaging component 10 may include a lens and a display screen (not shown in
In the wearable monocular glasses according to the embodiments of the present disclosure, the direction sensor 20 is configured to detect the wearing state of the wearable monocular glasses. In the embodiments of the present disclosure, the position of the direction sensor 20 on the optical imaging circuit 10 is not particularly limited.
Taking the gravity sensor as an example, the principle of piezoelectric effect is usually used to determine the direction of gravity. For an isopolar crystal having no symmetrical center, in addition to a deformation of the crystal, an external force applied on the crystal will change a polarization state of the crystal, and an electric field is established inside the crystal. Such a phenomenon of polarizing a medium due to a mechanical force is known as a positive piezoelectric effect. The gravity sensor takes advantages of the characteristics that the crystal is deformed due to accelerations. Since this deformation may cause a voltage, the acceleration may be converted into a voltage for output as long as a relationship between the generated voltage and the applied acceleration is calculated. For example, a gyro sensor is provided with a gyro in its interior. Since an axis of the gyro is always parallel to an initial direction due to the gyro effect, the direction may be calculated according to a deviation from the initial direction. With the provided direction sensor 20, the state of the optical imaging component 10 may be determined by fixing the relative position between the direction sensor 20 and the optical imaging component 10. Therefore, in the wearable monocular glasses according to the embodiments of the present disclosure, the arrangement position of the direction sensor 20 on the optical imaging component 10 is not specifically limited. For example, the direction sensor 20 may be provided above the optical imaging component 10 as shown in
In the wearable monocular glasses according to the embodiments of the present disclosure, the wearing state of the wearable monocular glasses refers to a directional state of the wearable monocular glasses which are fitting with the left eye or a directional state of the wearable monocular glasses which are fitting with the right eye. For example,
In the wearable monocular glasses according to the embodiments of the present disclosure, the frame 30 is fixedly connected with the optical imaging component 10, which means that the frame 30 is directly connected with the optical imaging component 10 or is connected with the optical imaging component 10 through a connector. The fixed connection herein refers to a fixed relationship between the frame 30 and the optical imaging component 10 after the installation is completed, so that the user may wear the wearable monocular glasses of the embodiments of the present disclosure by fixing the frame 30 on the head or the like. However, in general, the frame 30 and the optical imaging component 10 are detachably connected with each other. That is, the fixedly connected frame 30 and the optical imaging component 10 may be separated by means of disassembly.
In the wearable monocular glasses according to the embodiments of the present disclosure, for the same wearable monocular glasses, the image for the left-eye wearing is flipped upside down with respect to the image for the right-eye wearing, and the switching of the image data may be realized after exchanging the left-eye wearing and the right-eye wearing by performing a corresponding processing on the image data. Therefore, the control circuit 40 is electrically connected with the direction sensor 20 and the optical imaging component 10 respectively, so that the control circuit 40 controls, according to the wearing state corresponding to the left eye or the wearing state corresponding to the right eye detected by the direction sensor 20, the image data in the optical imaging component 10 to be converted by a corresponding algorithm, so as to obtain the image data corresponding to the wearing state of the wearable monocular glasses.
In the wearable monocular glasses according to the embodiments of the present disclosure, the shape of the frame 30 is not particularly limited as long as the wearable monocular glasses can be fixed to the head of the wearer for both the left-eye wearing and the right-eye wearing, so that the wearable monocular glasses do not shake or fall off either the wearer wears them on the left eye or on the right eye.
An embodiment of the present disclosure provides wearable monocular glasses, including: an optical imaging component; a direction sensor which is fixed relative to the optical imaging component and configured for detecting a wearing state of the wearable monocular glasses; a frame fixedly connected to the optical imaging component for enabling a user to wear the wearable monocular glasses in different wearing states; and a control circuit electrically connected with the direction sensor and the optical imaging component respectively for outputting image data corresponding to the wearing state of the wearable monocular glasses to the optical imaging component. The wearing state of the wearable monocular glasses is detected by the direction sensor having a fixed relative position with the optical imaging component, and the detected signal is transmitted to the control circuit so that the control circuit may adjust the image data to the image data corresponding to the wearing state of the wearable monocular glasses correspondingly according to the wearing state of the wearable monocular glasses, so that a positive picture display matching with the wearing state may be realized in spite of the left-eye wearing state and the right-eye wearing state of the wearable monocular glasses. Meanwhile, the frame is fixedly connected to the optical imaging component, thereby the user may wear the wearable monocular glasses and a wearing stability of the wearable monocular glasses may be ensured during wearing.

The magnetic attraction member 62 is disposed around the plurality of signal terminals 61, and the two connection parts 60 are mutually fixed by the magnetic attraction force. In order to prevent the magnetic field generating the magnetic attraction force from affecting the signal transmission of the wearable monocular glasses, the insulating layer 63 is provided around an outer surface of the magnetic attraction member 62. The plurality of signal terminals 61 are protruded from the connection surface of the connection part 60 for mutual adsorption and signal transmission with the connection surface of the other connection part 60, and therefore, the insulating layer 63 is not provided on the connection surface of the connection part 60.

It should be noted that the magnetic metal described in the embodiments of the present disclosure is not limited to a specific metal type, and may be any metal that is made of a metal material having a property of being adsorbed by the magnet 622.

Due to the nature of the magnetic metal 623 and the magnet 622, the magnet 622 may magnetically adsorb the magnetic metal as long as the magnet 622 and the magnetic metal are close to each other. Therefore, compared to the case where the magnetic attraction member 62 is the electromagnetic generator 621, when the magnetic metal 623 and the magnet 622 are used as the magnetic attraction member 62, it is unnecessary to increase the current applied to the magnetic attraction member 62 for making the electromagnetic generator 621 generate a magnetic field.
According to another aspect of the embodiments of the present disclosure, a method for controlling wearable monocular glasses is provided. As shown in

The preset state is one of the wearing states of the wearable monocular glasses. If the current wearing state of the wearable monocular glasses is not the preset state of the wearable monocular glasses, then the image data corresponding to the preset state of the wearable monocular glasses is adjusted to the image data corresponding to the current wearing state of the wearable monocular glasses and then is displayed.
As shown in
In another aspect of the embodiments of the present disclosure, a combined binocular glasses system is provided. As shown in
As shown in
In the above specific description of the structural principle of the wearable monocular glasses and the connection manner between any two wearable monocular glasses, how the two wearable monocular glasses are combined by the connecting parts 60 to form the combined binocular glasses system has been described in detail, which is not elaborated here.
According to still another aspect of the embodiments of the present disclosure, a method for controlling a combined binocular glasses system is provided. As shown in
In S201, the first wearable monocular glasses 01 determine whether the first wearable monocular glasses 01 and the second wearable monocular glasses 02 are connected.
In S202, when it is determined that the first wearable monocular glasses 01 and the second wearable monocular glasses 02 have been connected, a data indication signal or image data is transmitted between the first wearable monocular glasses 01 and the second wearable monocular glasses 02, the data indication signal being used to indicate binocular display image data.
In S203, the first wearable monocular glasses 01 and the second wearable monocular glasses 02 respectively acquire individual current wearing states, and display according to the image data corresponding to the current wearing states.
Firstly, a connection signal is acquired by the first wearable monocular glasses 01 and it is determined whether the first wearable monocular glasses 01 and the second wearable monocular glasses 02 are connected. If there is no connection, the first wearable monocular glasses 01 still transmit and display with a monocular signal.
Secondly, there are at least two ways for determining whether the first wearable monocular glasses 01 and the second wearable monocular glasses 02 are connected. The first way may be that the control circuit 40 of each wearable monocular glasses sends a connection signal to at least one signal terminal 61 of its own connection part 60, and if the control circuit 40 of the other wearable monocular glasses at the opposite end receives the connection signal, it may be determined that the two wearable monocular glasses are connected as a combined binocular glasses system. The second way may be that a binocular control switch may be provided on the wearable monocular glasses, after the user connects the two wearable monocular glasses through the connection parts 60, the user may manually trigger the binocular control switch on the wearable monocular glasses at any side to determine the binocular connection, and the binocular display may be performed. Alternatively, the binocular connection may also be determined in other manners, which is not specifically limited in the embodiments of the present disclosure.
After it is determined that the first wearable monocular 01 and the second wearable monocular 02 are connected, a data indication signal or image data is transmitted between the first wearable monocular glasses 01 and the second wearable monocular glasses 02. The first wearable monocular glasses 01 and the second wearable monocular glasses 02 forming the combined binocular glasses system also obtain their own current wearing states through the respective control circuits 40, and correspondingly output the image data corresponding to the current wearing states.
The foregoing is merely specific implementations of the present disclosure, and the protection scope of the present disclosure is not limited thereto. Modifications and substitution which may be easily made by those skilled in the art within the technical scope disclosed by the present disclosure should all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be defined by the protection scope of the claims.
