When the traditional VR head display is used in cooperation with a keyboard, the VR head display mostly depends on self built-in battery power supply, and the standby time is generally short. Increasing the battery capacity of the VR head means increasing the overall weight of the VR head, which can significantly reduce the comfort of wearing the VR head. Aiming at the technical problem that the standby time of equipment is not long enough when the VR head is obviously used in cooperation with a keyboard, the application provides the following technical scheme:

referring to fig. 1, the present invention provides a VR office equipment 100, which includes an external input device 12 and a VR head display 14. The external input device 12 is provided with a charging stand 124 on its housing, and the charging stand 124 is electrically connected to the internal battery of the external input device 12. The VR head display 14 has a charging plug 142 on the housing, and the charging plug 142 is electrically connected to the internal battery of the VR head display 14. The charging plug 142 is used to connect to the charging dock 124 to charge the internal battery of the VR head display 14. The battery capacity of the internal battery of the external input device 12 is greater than the battery capacity of the internal battery of the VR headset 14.

It is to be appreciated that the external input device 12 can be any of a variety of peripherals commonly used in the art for human interaction with the VR headset 14, such as, but not limited to, a keyboard, a touchpad, a joystick, or any of a variety of motion capture devices, such as a user hand motion capture device. For convenience of explanation, a scenario in which the external input device 12 with a large capacity battery is the keyboard 12 will be described below as an example, and it will be understood by those skilled in the art that the charging function of the VR head display 14 is similar to that of the keyboard 12 when the external input device 12 with a large capacity battery is another input peripheral.

Alternatively, the keyboard 12 may be a body of any type of conventional keyboard in the art, and mainly includes a bottom plate of the keyboard 12, a keyboard panel 122, keys, keycaps, keyboard circuits, a power supply, and the like. The charging base 124 can be various types of charging sockets in a wired charging mode, or a wireless charging base, and the charging plug 142 is matched with the charging base 124 in type. The power supply source may be a large-capacity battery built in the keyboard 12, such as various types of rechargeable batteries, and may further include an interface power source for charging the keyboard 12 itself or taking power from the outside, such as but not limited to a power line in a USB interface, and may be determined according to the power supply mode adopted by the keyboard 12.

The charging base 124 can be disposed on the front surface of the keyboard panel 122 (i.e., the housing of the external input device 12), i.e., facing the same direction as the key cap, or disposed on the peripheral side surface of the keyboard panel 122, as long as it can be used for connecting the charging plug 142 of the VR head display 14 without affecting the normal use of other components (e.g., indicator light, key cap, etc.) on the keyboard panel 122. The charging base 124 can be embedded in the keyboard panel 122, and the socket of the charging base 124 and the mounting opening formed on the keyboard panel 122 are coplanar or protrude out of the keyboard panel 122 by a certain size, so that the overall appearance of the keyboard 12 keeps a better flatness, and the charging base 124 is protected from being worn and torn while being convenient to carry and use. The charging base 124 can also be directly welded or clamped on the keyboard panel 122, that is, the main structure of the charging base 124 is disposed on the outer surface of the keyboard panel 122 and connected to the power supply inside the keyboard 12 through the binding line, so that the charging base 124 can be replaced conveniently when the charging base 124 fails. While the above arrangement of the charging base 124 is illustrative, those skilled in the art can also adopt other arrangements according to the docking requirements of the charging base 124 on the keyboard panel 122 and the charging plug 142 on the VR headset 14.

The position of charging plug 142 on the shell of the VR head display 14 can be any position of the outer surface of the periphery of the shell, for example, when the VR head display 14 is worn on the head of a user, charging plug 142 can be located on any position of the outer surfaces of the two sides of the shell of the VR head display, and can also be located on any position of the surface of the shell of the VR head display 14, as long as the charging plug can be conveniently docked with the charging seat 124 on the keyboard 12 to realize charging and does not affect the wearing and use of the VR head display 14 by the user. In some embodiments, the charging plug 142 can be embedded in the housing of the VR headset 14, and the charging plug 142 is coplanar with or protrudes from the surface of the housing of the VR headset 14 by a certain dimension, so that the overall appearance of the VR headset 14 can maintain a good flatness while protecting the charging plug 142 from abrasion. Charging plug 142 can also be directly welded or the joint is on the shell of the first apparent 14 of VR, and the surface of shell is located to charging plug 142's major structure promptly, is connected to the inside built-in battery of the first apparent 14 of VR through the binding line, can be when charging plug 142 trouble like this, conveniently change charging plug 142.

The external input device 12 has two basic types, wireless and wired, and in the case of the keyboard 12, the keyboard 12 has two types, wireless keyboard and wired keyboard, and a large-capacity battery is provided inside the keyboard, so that the large-capacity battery can be charged for a small-capacity built-in battery on the VR head display 14. Thus, when the VR head display 14 is used in cooperation with the external input device 12, the external input device 12 is used to charge the VR head display 14, which can greatly prolong the standby time and the endurance time of the VR head display 14.

Above-mentioned VR office equipment 100, through set up charging plug 142 and charging seat 124 on the external input equipment 12 that the head of VR shows 14 and the supporting use respectively, when the head of VR shows 14 in the use or when the electric quantity appears after the end of using and is not enough, the head of VR shows 14 can be connected with external input equipment 12, charge for the head of VR shows 14 by external input equipment 12 through wired or wireless mode, show 14 in time supplementary electric quantity for the head of VR and use continuation of the journey or stand-by continuation of the journey. So, can be under the prerequisite that does not increase the first weight that 14 appears of VR, by external input device 12 for the first 14 that appear of VR provides convenient charging to it is long when the standby of the first 14 that appear of VR extends by a wide margin, has solved the equipment standby problem of being not enough for a long time.

In one embodiment, the charging dock 124 is a docking member that is embedded in the peripheral side surface of the housing of the external input device 12. The charging plug 142 is a plug-in member that is embedded in the outer peripheral side surface of the VR head 14.

It is to be appreciated that in this embodiment, a connector may be employed to enable wired charging of the VR head display 14 by the external input device 12. For ease of understanding, a scenario in which the keyboard 12 is the external input device 12 is taken as an example: taking the surface of the keyboard panel 122 where the key caps are located as the upper surface, the connectors may be embedded in any peripheral side surface of the peripheral side of the keyboard panel 122, or embedded in the upper surface of the keyboard panel 122, such as the keyboard panel 122 region except the key caps and the keyboard indicator lamps. The connecting terminal of the connector is electrically connected to the power supply of the keyboard 12, the interface of the connector is exposed on the keyboard panel 122, the interface plane and the panel are level, concave or convex, and the interface plane and the panel can be determined according to the specific embedded position of the connector and the convenience needed by butting with the plug-in.

Accordingly, inserts embedded in the housing of the VR head display 14 can be embedded in either of the two side outer surfaces of the housing, and can also be located on the front surface of the housing of the VR head display 14. The terminals of the insert are electrically connected to the internal battery of the VR head 14, the plug of the insert is exposed on the outer surface of the shell, the plug can be flush with, recessed into, or protruding from the surface of the shell, and can be specifically determined according to the specific embedded position of the insert and the convenience required for docking with the connectors.

Specifically, the VR head display 14 may be wired to the keyboard 12 by inserting a plug-in to connect the VR head display 14 to the keyboard 12 during periods of suspended use of the VR head display 14. During use of the VR head display 14, the plug-in and connector may also be connected via a connection cord, thereby connecting the VR head display 14 to the keyboard 12, and charging the VR head display 14 by the keyboard 12 via a cord provides on-line endurance. By adopting the connector as the charging seat 124 and the charging plug 142, the wired charging of the VR head display 14 by the keyboard 12 can be realized, the charging reliability is high, and the online charging during the use period of the VR head display 14 is supported.

Referring to fig. 2, in one embodiment, the charging base 124 is a magnetic charging base embedded in the peripheral surface of the external input device 12. The charging plug 142 is a magnetic charging plug embedded in the peripheral surface of the shell of the VR head 14.

It is understood that in this embodiment, the wired or wireless charging of the VR head display 14 by the external input device 12 may be achieved using a magnetic-type connector. For ease of understanding, a scenario in which the keyboard 12 is the external input device 12 is taken as an example: taking the surface of the keyboard panel 122 where the key caps are located as the upper surface, the magnetic charging socket may be embedded in any peripheral side surface of the peripheral side of the keyboard panel 122, or embedded in the upper surface of the keyboard panel 122, such as the areas of the keyboard panel 122 except the key caps and the keyboard indicator lamps. The connection terminal of the magnetic charging stand is electrically connected to the power supply of the keyboard 12, the interface of the magnetic charging stand is exposed on the keyboard panel 122, the interface plane is flush with the panel, recessed into the panel or protruded out of the panel, and the connection terminal can be determined according to the specific embedded position of the magnetic charging stand and the convenience required for the butt joint of the magnetic charging stand and the magnetic charging plug-in.

Correspondingly, the magnetism that inlays to establish on the casing of the first apparent 14 of VR magnetism inserts that charges can inlay to locate any one side in the both sides surface of casing, can also be located the first apparent 14 positive casing surface of VR. The connecting terminal of the magnetic charging plug-in is electrically connected to the built-in battery of the VR head display 14, the plug of the magnetic charging plug-in is exposed on the outer surface of the shell, the magnetic charging plug-in can be flush with, recessed into or protruding out of the surface of the shell, and the magnetic charging plug-in can be determined according to the specific embedded position of the magnetic charging plug-in and the convenience required for the butt joint with the magnetic charging seat. The charging seat is inhaled to magnetism and the plug-in components that charge of magnetism all can be wireless charging parts, also can be wired charging parts, specifically can choose for use according to practical application needs. It should be noted that the magnetically attractive charging insert in fig. 2 is shown in dotted lines on the outer surface of the housing, and is hidden by the housing from the current viewing angle.

Specifically, when the VR head display 14 is suspended, the magnetic charging plug-in unit is close to the magnetic charging seat and automatically attracted together by approaching the VR head display 14 to the keyboard 12, so that the VR head display 14 is connected with the keyboard 12, and the VR head display 14 is charged by the keyboard 12 in a wireless or wired manner. Through adopting the connector of formula of inhaling as above-mentioned charging seat 124 and charging plug 142, can realize keyboard 12 to the first wireless or wired charging of 14 of VR, it is more convenient to charge the high and operation of charging of reliability.

In one embodiment, the external input device 12 includes a keyboard 12, a joystick, or a touchpad. Optionally, in this embodiment, the external input device may be any one of the keyboard 12, the handle, or the touch panel with a built-in large-capacity battery, or may be any combination of the keyboard 12, the handle, or the touch panel with a built-in large-capacity battery, and may be specifically determined according to the need of interactive input when the user uses the VR headset 14. Preferably, the keyboard 12 is used as the main external input device 12, so that the size advantage of the keyboard 12 can be fully utilized, and a built-in battery with larger capacity is arranged, thereby providing more durable cruising ability for the VR head display.

Referring to fig. 3, in one embodiment, an auxiliary controller 16 is further disposed inside the external input device 12. The auxiliary controller 16 is electrically connected to the built-in battery of the external input device 12. The secondary controller 16 is communicatively coupled to the host of the VR headset 14 for processing VR application data and outputting video stream data corresponding to the VR application data to the host of the VR headset 14.

In the present embodiment, the auxiliary controller 16 may be any type of chip device or processor board card having computing processing capabilities and capable of providing a corresponding general purpose input/output interface, data interface, and/or wireless communication module. The secondary controller 16 undertakes a portion of the computing traffic originally processed on the host of the VR head display 14 by installing a portion of the application software that was originally present on the host of the VR head display 14. For example, a partially power hungry and less real-time demanding VR application in the VR head display 14 is run in an additional auxiliary controller 16 on the external input device 12. The VR application data generated locally by the auxiliary controller 16 on the external input device 12 is sent to the VR head display 14 for playback, either by wire or wirelessly, in the form of video stream data. The VR application data may also be other application data that the secondary controller 16 connects to the cloud server associated with the current VR scenario and obtains from the VR application on the cloud server.

Specifically, the added auxiliary controller 16 is used to undertake part of the calculation processing function of the host of the VR head display 14, and the auxiliary controller 16 processes locally generated VR application data or connects with cloud-acquired VR application data, and sends the VR application data to the host of the VR head display 14 in the form of video stream data. The host of the VR head display 14 can complete the original processing procedures such as calculation and play preprocessing of the received video stream data through the built-in low-power consumption video stream processing unit, for example, the solved VR application content is output to the VR head display 14 for display, the display content can be combined with the external picture taken by the VR head display 14, and a virtual reality or mixed display scene is rendered with the external picture as a background (for example, the picture applied by APP is suspended in the air of the VR scene, and the background is a real scene).

By additionally arranging the auxiliary controller 16 on the external input equipment 12, a part of the VR head display 14 with high power consumption and low real-time requirement is put into the auxiliary controller 16 on the external input equipment 12 for operation; the auxiliary controller 16 can directly take power from the internal battery of the external input device 12, so that the transferred part of the VR application does not consume the power of the internal battery of the VR head display 14. Moreover, the host of the VR head display 14 can greatly save the power of the battery built in the head display because the host no longer needs to process the aforementioned computing service of the VR application, so that the power consumption of the host of the VR head display 14 can be reduced, thereby further increasing the standby time of the VR head display 14.

Referring to fig. 4, in an embodiment, the external input device 12 is further provided with a first wireless communication module 126. The first wireless communication module 126 is electrically connected to the secondary controller 16. A second wireless communication module 144 is also provided on the VR head display 14. The second wireless communication module 144 is electrically connected to the host of the VR head display 14.

It is understood that in this embodiment, the auxiliary controller 16 is connected to the host of the VR headset 14 in a wireless communication manner, and in some embodiments, can also be wirelessly connected to the cloud. A first wireless communication module 126 is also provided on the external input device 12 and, correspondingly, a second wireless communication module 144 is provided on the VR headset 14 for enabling wireless communication between the external input device 12 and the VR headset 14 and/or the cloud server.

Taking the scenario that the external input device 12 is a keyboard 12 as an example, the first wireless communication module 126 may be disposed on an outer surface of the keyboard panel 122 (i.e., a side where the keycap is located), or disposed on an inner surface of the keyboard panel 122 (i.e., a side where the keyboard circuit is located), and a specific location of the first wireless communication module may be determined according to a need for efficient transmission of wireless signals. Similarly, the second wireless communication module 144 can be disposed on an outer surface of the housing of the VR head display 14 (i.e., a side exposed to an external environment) or an inner surface of the housing of the VR head display 14 (i.e., an inner side of the VR head display 14), and the specific location of the second wireless communication module can be determined according to the efficient transmission requirement of the wireless signal. Note that the dashed device in fig. 4 indicates that it is located inside the keyboard 12.

The second wireless communication module 144 is adapted to the first wireless communication module 126, and wireless signal transceiving between the two enables wireless transmission of data between the auxiliary controller 16 and the host of the VR headset 14. Specifically, VR application data generated locally and/or obtained from the cloud by the auxiliary controller 16 is wirelessly transmitted to the second wireless communication module 144 through the first wireless communication module 126 in the form of video stream data. The second wireless communication module 144 receives the video stream data and outputs the video stream data to the host of the VR head display 14, and the host can process and output the received video stream data for display. Other data transmissions between the auxiliary controller 16 and the VR headset 14, such as operating signals from external input devices 12, such as a keyboard 12, a joystick or a touchpad, may also be performed via the wireless communication module.

By wirelessly communicating data between the auxiliary controller 16 of the external input device 12 and the VR head display 14, the VR head display 14 can move within a wider range during use than a wired transmission, is more flexible and convenient to use, and can avoid increasing the weight of the VR head display 14.

In one embodiment, the auxiliary controller 16 includes an MCU chip, FGPA chip, CPU chip, GPU chip, or raspberry. Optionally, in this embodiment, the auxiliary controller 16 may be an MCU chip, a CPU chip, a GPU chip, or an FPGA chip, which has the above-mentioned computation and data input/output functions, or may be a raspberry group. The device has strong calculation processing capacity, strong functions and small volume, can be easily loaded and run with the existing calculation and control application in the field to support the required processing functions, and is convenient to update the application. Therefore, when applied as the auxiliary controller 16, the circuit structure inside the keyboard 12 can be prevented from being greatly increased, and at the same time, the application cost thereof is reduced, the content calculation and the output efficiency of the video stream data are improved, and the display performance of the VR head display 14 is improved.

In one embodiment, a camera, IMU unit, and magnetometer are also disposed on the housing of the VR head display 14. The camera, IMU unit and magnetometer are electrically connected to the host of the VR head display 14, respectively. The camera is used for shooting a scene picture outside the VR head display 14. The IMU unit is used to acquire pose data of the VR headset 14. The magnetometer is used to acquire orientation data of the VR head display 14.

It is understood in the art that the VR head display 14 needs to perform spatial Localization And SLAM (Simultaneous Localization And Mapping) calculation when displaying content, And this part of calculation can be implemented by the host computer directly after acquiring data through an external sensor. In this embodiment, the VR head display 14 may also include sensor elements such as a camera, an IMU unit (i.e., an inertial measurement unit), and a magnetometer, so that external scene images, attitude data and orientation data of the VR head display 14 are directly collected on the VR head display 14 for performing required spatial positioning and SLAM calculation. The specific computational processing may be performed by the host computer of the VR headset 14 or may be performed on the auxiliary controller 16 of the keyboard 12.

Through the integration setting of above-mentioned sensing device and the first 14 that show of VR, can make the first 14 that show of VR can realize the data acquisition and outside picture with high efficiency and shoot.

In one embodiment, the auxiliary controller 16 is further configured to receive the scene, the pose, and the orientation data, convert the scene, the pose, and the orientation data into corresponding positioning data, and transmit the positioning data to the VR headset 14 for display.

Optionally, in this embodiment, the host of the VR head display 14 may further wirelessly send data acquired by each sensing device to the auxiliary controller 16 on the external input device 12, and the auxiliary controller 16 undertakes required spatial positioning and SLAM calculation services, so that the VR head display 14 is mainly responsible for processing tasks such as data acquisition and VR display, and thus power consumption of the host of the VR head display 14 may be further reduced, and an effect of further increasing standby time of the VR head display 14 is achieved.

Specifically, the auxiliary controller 16 may receive and locally process each sensing and/or image data collected on the VR head 14 through wireless, or may indirectly obtain each sensing and/or image data collected on the VR head 14 through a cloud and locally process the data. The auxiliary controller 16 performs local processing such as spatial positioning and SLAM calculation to generate positioning data, and the positioning data can be directly wirelessly transmitted to the VR head display 14 for processing and displaying, or the positioning data can be combined with VR application data to generate a video stream and then transmitted to the VR head display 14 for processing and displaying. Therefore, the power consumption of the host of the VR head display 14 can be further reduced, and the duration of endurance is prolonged.

In one embodiment, the first wireless communication module 126 is a bluetooth module or a WIFI module. The second wireless communication module 144 is a bluetooth module or a WIFI module.

Optionally, the first wireless communication module 126 and the second wireless communication module 144 may be bluetooth modules, so that the keyboard 12 and the VR headset 14 can be connected via bluetooth to achieve low power consumption data transmission. The first wireless communication module 126 and the second wireless communication module 144 may also be WIFI modules, thereby enabling data transfer between the keyboard 12 and the VR headset 14 via a WIFI connection. In some embodiments, the first wireless communication module 126 and the second wireless communication module 144 can be other types of wireless communication modules as long as the wireless data transfer rate requirements between the secondary controller 16 and the host of the VR headset 14 can be met.

Referring to fig. 5, in one embodiment, a positioning tag 128 is further disposed on the keyboard panel 122. The positioning tabs 128 include at least two and are symmetrically disposed on the keyboard panel 122 for indicating the spatial position of the keyboard 12 to the VR headset 14.

It is to be appreciated that the positioning tag 128 can be any tag that can be distinguished from the environment surrounding the keyboard 12 and attached to the keyboard panel 122 as a VR avatar capturing the six degree-of-freedom position of the keyboard 12. In some embodiments, the positioning tag 128 may be a barcode, a light emitting tag, a light absorbing tag, a magnetic tag, or other tag. The position of the positioning tab 128 on the keyboard panel 122 may be, but is not limited to, on any pair of opposite corners of the periphery of the keyboard panel 122, or on any pair of opposite sides of the periphery of the keyboard panel 122. The positioning tab 128 may be, but is not limited to, attached directly to the keyboard panel 122, or attached to the keyboard panel 122 by screws, or integrally molded with the keyboard panel 122 to form an embedded positioning tab 128.

Specifically, the camera provided on the VR head 14 is used to obtain the six-degree-of-freedom position of the keyboard 12 in the real space: for example, a visual recognition camera captures the positioning tags 128 disposed on the real keyboard 12, captures the positions of the positioning tags 128 through computer vision techniques known in the art, calculates the relative positions and rotational orientations of the positioning tags 128 in the VR image, and compares the relative positions and rotational orientations with the known absolute positions of the positioning tags 128 on the hardware, so as to calculate the current position and orientation of the keyboard 12 from the camera and simulate a virtual keyboard for display in the VR environment.

Through the setting of above-mentioned location label 128, the position that real keyboard 12 can also be detected to the first 14 that show of VR to show and carry out the VR demonstration to real keyboard 12 in the VR scene, need not the frequent head-lowering of user and look for keyboard 12, thereby convenience of customers operation improves VR office equipment 100's availability factor.

Referring to fig. 6, in one embodiment, the keyboard panel 122 is further provided with a transceiver sensor 129 and a detection chip 130. The transceiving sensor 129 comprises a plurality of sensing elements, which are respectively disposed on the keyboard panel 122 and correspond to the key caps one by one, and are used for detecting finger approaching signals of the key caps according to the reflection principle. The detecting chip 130 is disposed on the keyboard 12 and electrically connected to each of the transceiving sensors 129, for scanning and acquiring the finger approach signal of each of the transceiving sensors 129 and sending the finger approach signal to the host of the VR headset 14. The finger proximity signal is used to indicate to the host computer that controls the VR head display 14 to display the finger position on the keyboard in the VR environment.

It is understood that the transceiver 129 may be an optical transceiver or an acoustic transceiver, such as but not limited to an infrared or other laser transceiver in each wavelength band, for detecting the presence or absence of an object approaching the defined area based on the difference between the emitted light and the received reflected light; or for example, an ultrasonic wave or other sound wave transceiver device with good linearity detects whether an object approaches the set region based on the difference between the transmitted sound wave and the received large reflected sound wave. Each of the transceiving sensors 129 may place all of the device structures on the keyboard panel 122 in the corresponding key cap coverage area, or place some of the device structures on the keyboard panel 122 in the corresponding key cap coverage area, and place some of the device structures on the keyboard panel 122 outside the corresponding key cap coverage area.

For example, the transmitting (or receiving) structure of the transceiving sensor 129 is disposed on the keyboard panel 122 near the peripheral side of the keycap (e.g., the gap between the areas of the keyboard panel 122 covered by two keycaps) outside the corresponding keycap covering area, and the receiving (or transmitting) structure of the transceiving sensor 129 is disposed on the keyboard panel 122 in the corresponding keycap covering area. For the lower part of the keycap of each key (i.e. the area of the keyboard panel 122 covered by the keycap), the number of the transceiving inductors 129 may be one, or may be two or more, and specifically may be determined according to the size of the keycap, the detection sensitivity, the detection precision, and the like, as long as the required detection purpose can be accurately and reliably achieved.

The detection chip 130 may be any chip device in the art having computing processing capability and capable of providing corresponding signal input/output interfaces, data interfaces and/or wireless communication modules, and the detection chip 130 may be a general or special scan processing chip existing in the art. The scanning of the sensing elements 129 by the detecting chip 130 may be real-time scanning or timing scanning, for example, but not limited to, real-time scanning the output signals of the sensing elements 129 and then transmitting the signals to the host of the VR headset 14 for processing. Or after scanning the output signal of each transceiver sensor 129 once, scanning is performed again at a certain time interval (e.g., at any interval of several tens of milliseconds to several hundreds of milliseconds), and the process is repeated. Thus, if the signals obtained by two successive scans at a certain time interval both include the corresponding finger approach signal when the finger is detected, it indicates that the user's finger is operating the keyboard 12, and thus, false touch or environmental interference can be effectively prevented. The detection chip 130 can package the scan data and send the scan data to the host of the VR headset 14 in a wired or wireless manner when all or part of the output of the transceiver sensor 129 is scanned.

The host of the VR head display 14 is loaded with an existing VR graphic engine in the field, and after the spatial position of the keyboard 12 acquired by the VR head display 14 and the finger proximity signal acquired by the scanning of the detection chip 130 are provided to the VR graphic engine for processing, a keyboard 12 can be simulated and displayed in a VR picture or the real keyboard 12 can be directly displayed in a VR scene picture, and at the same time, a keycap triggered by a finger on the keyboard 12 is correspondingly displayed, or a hand of a user on the keyboard 12 is simulated and displayed, and particularly, the VR graphic engine can be selected and applied according to the needs of the user in an actual application scene. In the schematic diagram of the keyboard structure shown in fig. 6, only a part of the key caps, i.e. the corresponding transceiving sensor 129, is shown, wherein the dashed line element represents an element located below the solid line element and shielded by the solid line element, for example, the transceiving sensor 129 is located on the keyboard panel 122 below the corresponding key cap, or for example, when the detecting chip 130 is disposed in the internal space between the keyboard panel 122 and the bottom plate; the detecting chip 130 can also be disposed outside the keyboard 12, such as the outer surface of the keyboard panel 122 or the outer surface of the bottom plate, which is not particularly limited in this embodiment.

Specifically, after the VR head display 14 obtains the spatial position of the keyboard 12 through the positioning tag 128 and displays the spatial position, when the user operates the real keyboard 12, the finger of the user approaches and triggers the corresponding key, and the transceiving sensor 129 under the corresponding key cap detects the approach of the finger and generates a finger approach signal correspondingly. The detection chip 130 obtains the output signal of each transceiver sensor 129 by scanning, that is, the obtained finger approach signal can be sent to the host of the VR head display 14 for processing, and the host of the VR head display 14 outputs corresponding video data, so that the VR head display 14 displays the corresponding finger position on the keyboard 12 displayed in the VR environment to prompt the user. For example, when a user presses a key on the real keyboard 12, the corresponding key on the keyboard 12 displayed in the VR environment is also pressed simultaneously.

The corresponding finger position display on keyboard 12 displayed in the VR environment may be, but is not limited to: for example, the triggered virtual key is highlighted directly; or after passing through the activated keys or the finger tip positions, a virtual hand is simulated in the VR environment, for example, the activated keys on the left keyboard 12 are identified as the fingers of the left hand, and the activated keys on the right keyboard 12 are identified as the fingers of the right hand. The keys from left to right correspond to a little finger to an index finger respectively, the thumb is usually placed on a space key, if the number of the activated keys is less than 4, the identification and judgment are carried out according to the sequence from the index finger to the little finger, for example, the index finger can be judged when only one activated key is available, the index finger and the middle finger can be judged when two activated keys are available, and the like; the right hand understands the same. The specific display mode may be determined according to the application scene needs of the VR headset 14 and the display modes supported by the VR headset.

Through the arrangement of the receiving and sending sensing part 129 and the detection chip 130, the positioning tag 128 is matched for application, so that the keyboard 12 can be accurately positioned and displayed in a VR environment, the finger position operated on the keyboard 12 can be accurately acquired and displayed, the visual angle of a user is liberated, the user does not need to frequently lower the head to find the position of the keyboard 12, and the purpose of further improving the use efficiency of the VR office equipment 100 is achieved.

Referring to fig. 7, in an embodiment, the transceiving sensor 129 is an infrared pair tube, and the key cap 121 is a key cap 121 transmitting infrared light. The infrared pair transistors are disposed on the keyboard panel 122 and located between the corresponding key caps 121 and the keyboard panel 122, and the transmitting and receiving surfaces of the infrared pair transistors are opposite to the key caps 121. The infrared pair transistors are electrically connected to the detection chip 130.

It can be understood that, in this embodiment, adopt infrared geminate transistors as receiving and dispatching sensing element 129, the corresponding key cap 121 that chooses for use that can see through the infrared light can make the infrared ray of infrared emission pipe transmission of infrared geminate transistors pass the perpendicular keyboard panel 122 of key cap 121 and upwards jet out, and can not receive and shelter from or cross and cause the interference with the light path of the infrared geminate transistors under other key caps 121. The infrared transmitting tube and the corresponding infrared receiving tube in each infrared pair of tubes are respectively electrically connected to each corresponding signal pin of the detection chip 130 to realize corresponding driving and signal scanning. The ratio of the infrared transmitting tube to the infrared receiving tube contained in the infrared pair tube can be 1:1, or 1: n, N is a positive integer greater than or equal to 2, such as but not limited to one infrared pair tube comprising 1 infrared transmitting tube and two or three paired infrared receiving tubes, so as to detect the approach of an object more sensitively.

The infrared pair transistors are mounted on the keyboard panel 122 in such a way that each infrared pair transistor is mounted in the area of the keyboard panel 122 covered by the corresponding keycap 121, so that the detection accuracy is high; the infrared transmitting tube (or infrared receiving tube) of the infrared pair tube can also be installed outside the coverage area of the corresponding keycap 121 and on the keyboard panel 122 near the periphery of the keycap 121 (for example, at the gap between the keyboard panel 122 areas covered by the two keycaps 121), and the infrared receiving tube (or infrared transmitting tube) of the infrared pair tube is installed on the keyboard panel 122 in the coverage area of the corresponding keycap 121, that is, in the keyboard panel 122 area below the keycap 121, so that the finger position detection can also be realized. Optionally, the infrared pair tubes may be installed on the keyboard panel 122 in the area covered by the keycap 121 and close to the user side, so that the fingers of the user usually extend from one side of the user to the keyboard 12 when typing, and the infrared pair tubes can be detected timely and reliably, so that the detection accuracy can be improved.

Specifically, when the real keyboard 12 is operated by the hand of the user, the infrared pair tube can determine whether a finger is approaching according to the intensity of the received infrared (reflected by the finger) after emitting and receiving the infrared. When the finger is above the keycap 121, the reflected infrared ray is stronger, and after the receiving intensity reaches a certain threshold value, a corresponding finger approaching signal can be generated to judge that the finger approaches. The infrared pair transistors are used as the receiving and transmitting induction part 129, so that the design and manufacturing cost is low and the detection reliability is high.

In one embodiment, the transceiver sensor 129 is an ultrasonic sensor and the key cap 121 is a key cap 121 that is transparent to ultrasonic waves. The ultrasonic sensor is mounted on the keyboard panel 122 and located between the corresponding key cap 121 and the keyboard panel 122, and the emitting surface of the ultrasonic sensor is opposite to the key cap 121. The ultrasonic sensor is electrically connected to the detection chip 130.

It can be understood that, in this embodiment, adopt ultrasonic sensor as receiving and dispatching response piece 129, the corresponding keycap 121 that chooses for use can be passed through the ultrasonic wave can make the ultrasonic wave that ultrasonic sensor transmitted pass the perpendicular keyboard panel 122 of keycap 121 and upwards emit, and can not receive to shelter from or cross and cause the interference with the ultrasonic wave route of the ultrasonic sensor under other keycaps 121. The ultrasonic sensors are electrically connected to corresponding signal pins of the detection chip 130, respectively, to implement corresponding driving and signal scanning.

Specifically, the ultrasonic sensors are mounted on the keyboard panel 122 in a manner that each ultrasonic sensor is mounted on the area of the keyboard panel 122 under the keycap 121; optionally, the ultrasonic sensor may be installed on the keyboard panel 122 in the area covered by the keycap 121 and close to the user, so that the user can use the reason that the fingers usually extend from one side of the user to the keyboard 12 when typing, and the ultrasonic sensor can detect the characters timely and reliably, thereby improving the detection accuracy.

When the real keyboard 12 is operated by the hand of the user, the ultrasonic sensor can judge whether a finger approaches by the intensity of the received ultrasonic wave (reflected by the finger after being blocked) after the ultrasonic wave is emitted. When a finger is above the keycap 121, the reflected ultrasonic wave is strong, and the finger approaching signal correspondingly generated after the receiving intensity reaches a certain threshold value is used for judging that the finger approaches. The ultrasonic sensor is used as the receiving and transmitting induction part 129, so that the detection accuracy and reliability are high.

In one embodiment, the transceiver sensor 129 is mechanically coupled to the keyboard panel 122 by welding, snap-fit or carrier frame.

It can be understood that, in the present embodiment, when the transceiving sensor 129 is mounted on the keyboard panel 122, for example, the above-mentioned infrared pair tube or ultrasonic sensor, or a laser sensor in other bands, the transceiving sensor 129 may be connected and fixed by using, but not limited to, common soldering, and may also be connected and fixed by using a snap-in manner, for example, the transceiving sensor 129 is inserted into a preset bayonet on the keyboard panel 122 for limiting and then is fixed by gluing. Alternatively, a carrier frame may be additionally provided between the keyboard panel 122 and the key caps 121 as an element mounting layer between the entire keyboard panel 122 and all the key caps 121. The carrying frame provides a loading part for each transceiving sensor 129, so that each transceiving sensor is uniformly installed on the carrying frame, the carrying frame can be integrally nested on each key to be arranged on the keyboard panel 122 in a stacked mode, each transceiving sensor 129 is located below the corresponding key cap 121, and the mounting and dismounting convenience is high.

The receiving and transmitting sensor 129 is installed on the keyboard panel 122 through the above-mentioned mechanical connection manner, and is flexible to manufacture and low in cost, so that the influence of the weight of the keyboard 12 on the use efficiency is effectively avoided.

In one embodiment, the detection chip 130 includes an MCU chip, an FGPA chip, a CPU chip, a GPU chip, or a raspberry chip.

Therefore, the circuit structure of the keyboard 12 can be simplified and the application cost thereof can be reduced and the detection output efficiency can be improved when the detection chip 130 is applied.

In one embodiment, the positioning tags 128 comprise two-dimensional code tags. The two-dimensional code label is attached to the peripheral side corner of the keyboard panel 122.

Alternatively, in the present embodiment, the peripheral side corner of the keyboard 12 may refer to any one of the four peripheral side corners of the keyboard 12. On the four peripheral side corners of the keyboard 12 (that is, the four top corners of the keyboard panel 122, for the case of other non-rectangular keyboard panels 122, it can be understood as four central symmetrical points on the peripheral side of the keyboard panel 122 in the same way), a two-dimensional code label may be attached to one of the four peripheral side corners, two or three of the four peripheral side corners may also be attached to any two or three of the four peripheral side corners, and the four peripheral side corners may also be attached to two-dimensional code labels respectively as visual feature points placed on the keyboard 12.

By using the two-dimensional code tag as the positioning tag 128, the acquisition of the six-degree-of-freedom position of the keyboard 12 in the space by the VR head display 14 is effectively realized, so that the user can directly operate the keyboard 12 by matching the display of the finger position after the VR head display 14 acquires the position of the keyboard 12 and performs VR display, and the user does not need to frequently lower the head to find the keyboard 12. In addition, the manufacturing and using cost of the two-dimensional code label is low, so that the high hardware cost of the VR keyboard 12100 can be avoided.

Wherein, every group of lamp beads at least contains one lamp bead. The power supply of the keyboard 12 can supply power to each lamp bead to support the lighting work of the lamp bead. Therefore, the camera carried on the VR head display 14 can capture the positions of the visual feature points through a computer vision technology, calculate the relative positions and the rotation orientations of the visual feature points in the VR image, and further compare the relative positions with the known absolute positions of the LED lamp beads or the infrared lamp beads on the keyboard 12, so that the position and the orientation of the current keyboard 12 from the camera can be calculated, and a virtual keyboard is simulated in a VR environment for displaying.
