The present invention is described in further detail below with reference to the attached drawing figures.
Fig. 1 illustrates a method flow diagram, which particularly shows a process of remote input to a VR device, in accordance with an embodiment of the present invention.
As shown in fig. 1, in step S1, the VR device projects its current display content to the display device of the computer device; in step S2, the computer device receives a local information input by the user; in step S3, the computer device encodes the input information; in step S4, the computer device sends the encoded input information to the VR device; in step S5, the VR device invokes its local input method to decode the encoded input information; in step S6, the VR device displays the input information at the target input position.
Referring to fig. 1, in step S1, the VR device projects its current display content to the display device of the computer device.
Here, the computer device includes, but is not limited to, any electronic device coupled with a display device, which can execute a predetermined process such as numerical calculation and/or logic calculation by executing a predetermined program or instruction, and generally includes a processor and a memory, the predetermined process is executed by the processor executing a program instruction prestored in the memory, or the predetermined process is executed by hardware such as ASIC, FPGA, DSP, or a combination of the two. Computer devices include, but are not limited to, Personal Computers (PCs), laptops, tablets, and the like.
VR devices are typically integrated VR devices, and specifically, VR head displays (virtual reality head-mounted display devices) with independent processors, and have independent computing, input, and output functions.
Wherein, the step of projecting the screen to the computer equipment by the VR equipment further comprises the following substeps:
and step S101, establishing a TCP connection between the VR device and the computer device through adb connection.
And the VR equipment is connected with the computer equipment through USB or WIFI, and the VR equipment and the computer equipment establish TCP network connection under the condition that the adb works normally.
Step S102, the VR device captures an image of its currently displayed content and sends the image to the computer device via the TCP connection.
The VR device captures images of its currently displayed content in real-time and sends them to the computer device so that the computer device can synchronize the VR device's currently displayed content.
Here, to reduce the amount of data processing and data transmission, the VR device may compare the currently captured image with the last captured image, and when the two are the same, the VR device does not transmit the currently captured image to the computer device, that is, only when the currently displayed content of the VR device changes, the changed displayed image is synchronized to the computer device.
Further, the current display image captured by the VR device may also be sent to the computer device after compression via a specific socket port of both TCP connections.
The computer equipment end is connected with the VR equipment end through the TCP, so that the input text of the computer equipment end can be rapidly sent to the VR equipment end, and the real-time performance is high.
Step S103, the computer apparatus renders the received image and displays the rendered image on its display device.
Here, the display device is typically a display.
Accordingly, the current display content of the VR device is synchronized to the computer device side. When the input requirement is presented in the display content, if the page comprises the input box or the input box is activated, the user can perform local input through the input device of the computer device so as to synchronize the local input to the VR device side.
In step S2, the computer device receives a local information input by the user.
Here, the local input of the user on the computer device can be performed through an input device, and the input device comprises a virtual keyboard and a physical keyboard, which are correspondingly provided with different input method configurations.
By browsing the VR device display content synchronized to the display means, the user uses the input means of the computer device to make an input when the input is needed, which input with respect to the input at the VR device side can be understood as a kind of "local input" at the computer device side.
In step S3, the computer device encodes the input information.
Here, the encoding method is typically UTF8 encoding, which can support a plurality of languages including chinese. Therefore, those skilled in the art will appreciate that the present invention is not limited to UTF8 encoding, and any other encoding scheme that can accommodate chinese or other language inputs may be used.
In step S4, the computer device transmits the encoded input information to the VR device.
And after UTF8 encoding is carried out on the input information by the computer equipment, the encoded input information is sent to the VR equipment through the TCP connection with the VR equipment. That is, the computer device side realizes the real-time acquisition of the user input and the real-time input synchronization of the user to the VR device.
In step S5, the VR device invokes its local input method to decode the encoded input information.
Here, the local input method requires an input sequence capable of supporting the input device on the computer device side to generate input information. For example, for input using a physical keyboard, the VR device may create a standard Android input method locally to be able to recognize the input sequence generated by the keystrokes. For input using a virtual keyboard, the VR device may, for example, invoke a native google input method to recognize the input sequence generated by the touch to the touchscreen.
In step S6, the VR device displays the input information at the target input position.
The target input position means a position in which the input focus is located in the currently displayed content. For example, the VR device may call the system function commitText () to send the input information into the currently focused text box.
Fig. 2 shows a system diagram, which particularly shows a system for remote input to a VR device, according to an embodiment of the invention.
As shown in fig. 2, system 20 includes VR device 210 and computer device 220. VR device 210 includes a screen projection device 211, a receiving device 212, a decoding device 213, and a presentation device 214. The computer device 220 comprises rendering means 223, encoding means 224 and transceiving means 225, and is coupled with display means 221.
The screen projection device 211 projects the current display content of the VR device 210 to the display device 221 of the computer device 220; the submitting means 221 of the computer device 220 receives local information input by the user; the encoding means 224 of the computer device 220 encodes the inputted information; the transceiver 225 of the computer device 220 transmits the encoded input information to the VR device 210, while the receiver 212 of the VR device 210 receives the encoded input information; the decoding means 213 of the VR device 210 invokes the local input method to decode the encoded input information; presentation device 214 of VR device 210 displays the input information at the target input location.
Specifically, still referring to fig. 2, the screen projection device 211 of the VR device 210 projects the currently displayed content to the display device 221 of the computer device 220.
Here, the computer device 220 includes, but is not limited to, any electronic device coupled with the display device 221, and can perform predetermined processes such as numerical calculation and/or logic calculation by executing a predetermined program or instruction, and generally includes a processor and a memory, the predetermined processes are performed by the processor executing a program instruction pre-stored in the memory, or the predetermined processes are performed by hardware such as ASIC, FPGA, DSP, or a combination thereof. Computer devices 220 include, but are not limited to, Personal Computers (PCs), laptops, tablets, and the like.
The VR device 210 is typically a VR all-in-one machine, and specifically is a VR head display (virtual reality head-mounted display device) with an independent processor, and has independent computing, inputting and outputting functions.
Wherein, the screen projecting operation of the screen projecting device 211 to the computer device 220 further comprises the following sub-operations:
the TCP connection is established between the screen-projecting device 211 and the transceiver 225 of the computer device 220 via an adb connection.
The screen projection device 211 and the transceiver 225 are connected through USB or WIFI, and when the adb works normally, the two establish a TCP network connection.
Subsequently, the screen-projecting device 211 captures an image of the content currently displayed by the VR device 210 and transmits the captured image to the transceiving device 225 of the computer device 220 via the TCP connection.
The screen projection device 211 captures images of the currently displayed content of the VR device 210 in real time and transmits them to the computer device 220 so that the computer device 220 can synchronize the currently displayed content of the VR device 210.
Here, to reduce the data processing amount and the data transmission amount, the screen projecting apparatus 211 may compare the currently captured image with the last captured image, and when the two are the same, the currently captured image and the last captured image are not transmitted to the computer device 220, that is, only when the currently displayed content of the VR device 210 changes, the changed displayed image is synchronized to the computer device 220.
Further, the current display image captured by the screen projecting device 211 can also be sent to the computer device 220 via a specific socket port of the TCP connection between the two after being compressed.
The computer device 220 and the VR device 210 are connected through TCP, so that the input text of the computer device 220 can be quickly sent to the VR device 210, and the real-time performance is high.
Next, the display device 221 of the computer apparatus 220 renders the received image and displays the rendered image.
Here, the display device 221 is typically a display.
Accordingly, the currently displayed content of VR device 210 is synchronized to computer device 220. When an input request is presented in the display, such as a page including an input box or an input box being activated, the user may make a local input via input device 222 of computer device 220 to synchronize the local input to VR device 210.
The rendering means 223 of the computer device 220 receives local information input by the user.
Here, the computer device 220 may also be coupled with an input device (not shown) so that a user's local input at the computer device 220 can be made through the input device. The input device comprises a virtual keyboard and a physical keyboard, and the virtual keyboard and the physical keyboard are correspondingly provided with different input method configurations.
By browsing the VR device display content synchronized to the display 221, the user uses the input 222 of the computer device 220 to make input when needed, which input may be understood as a "local input" at the computer device side relative to the input at the VR device side.
Then, the encoding means 224 of the computer device 220 encodes the input information, and the transceiver means 225 transmits the encoded input information to the VR device 210.
Here, the encoding method is typically UTF8 encoding, which can support a plurality of languages including chinese. Therefore, those skilled in the art will appreciate that the present invention is not limited to UTF8 encoding, and any other encoding scheme that can accommodate chinese or other language inputs may be used.
When the encoding device 224 performs UTF8 encoding on the input information, the transceiver 225 transmits the encoded input information to the VR device 210 through a TCP connection with the VR device 210. That is, computer device 220 enables real-time acquisition of user input and synchronization of the user's real-time input to VR device 210.
Next, the receiving means 212 of the VR device 210 receives the encoded input information, and the decoding means 213 invokes its local input method to decode the encoded input information.
Here, the local input method requires an input sequence capable of supporting the input device on the computer device side to generate input information. For example, for input using a physical keyboard, the decoding apparatus 213 may create a standard Android input method locally to be able to recognize the input sequence generated by the key strokes. For input using a virtual keyboard, the decoding means 213 may, for example, invoke a native google input method to recognize the input sequence generated by the touch to the touch screen.
Subsequently, presentation device 214 of VR device 210 displays the input information at the target input location.
The target input position means a position in which the input focus is located in the currently displayed content. For example, the presentation means 214 may call the system function commitText () to send the input information into the currently focused text box.
