Description
BACKGROUND OF THE INVENTION

Cloud-computing technologies offer intuitive methods for leveraging resources and improving performance. Cloud-computing has become popular in both gaming and workstation environments. Historically, an application such as a video game or productivity application was executed using a personal computer (PC) or using a console attached to a television. A user may have purchased an application or game, which was loaded onto the PC or inserted into the game console and then executed in a well-known manner


More recently, application and gaming resources have moved to the “cloud.” A client device may connect to a server within the cloud having the resources necessary for executing the application or game. The client device simply acts as a terminal for a user to access the resources on the server and in turn execute the application or game.


However, cloud-computing technologies also create certain challenges. One such challenge is access to various peripheral devices that may be physically located on a device other than the device actually requiring functionality of the peripheral device. For example, a peripheral device may be connected to a client device that accesses a server within a cloud. The server may provide a virtual desktop for the client device, however the server device may have no knowledge about or access to the peripheral device connected to the client device.


Existing solutions that transfer functionality of well-known and tightly defined peripheral devices over special purpose protocols. After a network transfer of data, the peripheral devices are “recreated” on the remote machine. However, these solutions only work with peripheral devices that are known about ahead of time and for which device drivers already exist on the remote machine.


Accordingly, a need exists to remedy these shortcomings

System and Method for Computer Peripheral Access from Cloud Computing Devices


Embodiments of the present invention provide methods and systems for computer peripheral access from cloud computing devices, for example, accessing a game pad connected to a client device. However, embodiments of the present invention can be applied to any peripheral device connected to any device.



FIG. 4 is a block diagram of a computer peripheral access system 400, according to embodiments of the present invention. The computer peripheral access system 400 includes peripheral device 410, client device 420, network 430, server computer 440, and virtual peripheral device 450. Peripheral device 410 and client device 420 are coupled by a peripheral bus 460. Server computer 440 and virtual peripheral device 450 are connected by a virtual peripheral bus 470.


Peripheral device 410 may be any peripheral device connected to a host computer, e.g., client device 420. Peripheral device 410 may expand the client device's 420 capabilities without being a part of its core computer architecture. Peripheral device 410 may be, but is not limited to, an input device, output device, and/or storage device. Some examples of peripheral device 410 include, but are not limited to: keyboard, mouse, touchscreen, camera, display, printer, hard drive, flash drive, etc.


Client device 420 may be any computing device similar to the one described in FIG. 2. In some embodiments, client device 420 may be a client within a cloud-computing environment. Client device 420 may access computing resources (hardware and software) which are available on server 440 via network 430. In some embodiments, client device 420 may be a mobile device such as a smartphone or tablet device. Often times, client device 420 may not include software drivers to enable proper functionality of peripheral device 410 and it may not be possible to install the software drivers on the client device due to, for example, operating system restrictions. There may be many reasons that client device 420 does not include software drivers. For example, mobile devices have limited amounts of memory and storage and it may not be feasible to include software drivers for a many various peripheral devices 410. Or, it may be difficult or inconvenient to access the necessary driver. However, many times a user may wish to connect a peripheral device 410 to the client device 420 for expanded functionality. In some embodiments, the peripheral device 410 may be a USB device such as a game controller, keyboard, or storage device.


In some cases, the client device 420 may include software drivers for select peripherals 410. In the case of mobile devices, the client device 420 may have software drivers installed for peripherals 410 that are typically used with a mobile device, such as, but not limited to, SD card, external speakers, etc. However, the client device 420 may not include software drivers for peripherals 410 that are typically used with client devices 420 other than mobile devices, such as, but not limited to gamepads and keyboards.


A system and method describing use of a peripheral device 410 with a client device 420 that does not have software drivers for the peripheral device 410 is described below.


Peripheral bus 460 may be any subsystem operable for transferring data between the peripheral device 410 and client device 420. In some embodiments, peripheral bus 460 may be a universal serial bus (USB), controller area network bus (CANbus), eSATA bus, FireWire bus, ExpressCard bus, etc. It should be appreciated that peripheral bus 460 may be a wired and/or wireless communication channel. For example, peripheral bus 460 may provide connectivity between peripheral bus 460 and client device 420 through IEEE 802.11 Wi-Fi communication.


Network 430 may include one or more wireless and/or wired components. In some embodiments, network 430 may include the Internet. Network 430 may be similar to network 350 of FIG. 3 and may include local area network and/or wide area network portions. In some embodiments, communication via client device 420 and server 440 over the network 430 is facilitated by use of a standardized protocol, e.g., TCP/IP.


Server 440 may be a computing device similar to server 340 of FIG. 3. Server 440 may reside within a cloud computing environment and include hardware and software computing resources made available for client device 420. Server 440 may communicate with client device 420 via a communication channel, for example, network 430. Additionally, server 440 may include one or more virtual desktops. In this particular example, server 440 includes four virtual desktops: virtual desktop A 442, virtual desktop B 444, virtual desktop C 446, and virtual desktop D 448. It can be appreciated that server 440 may include any number of virtual desktops. Each virtual desktop may be used to load balance resources of server 440. The virtual desktops 442-448 may be transparent to an end user who may only see the server 440 on the network 430. In some embodiments, each virtual desktop 442-448 may be dedicated to a specific application (e.g., email, word processing, graphics editing, gaming, etc.)


Server 440 may be virtually connected to a virtual peripheral device 450. Virtual peripheral device 450 may be a virtual instance of peripheral device 410 created and used using the systems and methods described herein. Communications between peripheral device 410 and client device 420, over peripheral bus 460, may be detected and captured. For example, if USB peripheral device 410 is connected to client device 420, data packets on the USB peripheral bus 460 may be detected and captured. In some embodiments, the raw data packets from the peripheral device 410 may be captured prior to client device 420 receiving and interpreting the data packets. In some embodiments, the data packets may be detected using a snooping mechanism on the peripheral bus 460.


In some embodiments, the client device 420 may not include any device drivers for peripheral device 410. The captured data packets from peripheral bus 460 may be transferred over network 430 to server 440. In some embodiments, server 440 may include device drivers for the peripheral device 410. If server 440 does not include device drivers for the peripheral device 410, server 440 may obtain and install the required device drivers via a communication channel, e.g. via the Internet.


Server 440 may load and enable the specific device driver for the peripheral device 410. In some embodiments, the server 440 may analyze the received raw data packets to determine the type of peripheral device 410 connected to client device 420 and to ultimately determine the specific device driver required for proper operation of peripheral device 410. Upon loading and/or enabling the device driver for peripheral device 410, server 440 may create a virtual instance (virtual peripheral device 450) of the peripheral device 410. In some embodiments, the raw data packets on peripheral bus 460 may continue to be snooped by the snooping mechanism and the raw data packets may continually be transferred to server 440. As such, any input or usage of peripheral device 410 may be emulated on virtual peripheral device 450 connected to server 440 via virtual peripheral bus 470 as if peripheral device 410 itself is connected to server 440.


In some embodiments, the captured raw data packets on peripheral bus 460 may be compressed and/or encrypted prior to being transferred to server 440 over network 430. The compressed and/or encrypted raw data packets may then be decompressed and/or decrypted at server 440. The compression and encryption of the raw data packets may result in bandwidth savings on network and increased security in the data transmission. Upon decompression and/or decryption, the raw data packets may be reconstructed bit-for-bit.


As a result, peripheral device 410 may be coupled with server 440 and communicate with server 440 as virtual peripheral device 450. Accordingly, whether or not client device 420 may be capable of enabling proper functionality of peripheral device 410 with client device 420 alone, peripheral device 410 may be operable to communicate with server 440 and therefore affect the execution of software or hardware on the server 440, which may in turn affect the execution of software or hardware on client device 420.



FIG. 5A is a block diagram of a client device 420, according to embodiments of the present invention. Client device 420 includes a processor 510, input device 520, memory 530, display 540, and computer-readable medium 550.


Processor 510 may be any general-purpose processor operable to carry out instructions on the client device 420. The processor 510 is coupled to other units of the client device 420 including input device 520, memory 530, display 540, and computer-readable medium 550.


Input device 520 may be any device that accepts input from a user. Examples may include a keyboard, keypad, or mouse. In some embodiments, a multi-touch pad may be an input device.


Memory 530 may be any magnetic, electronic, or optical memory. Memory 260 includes two memory modules, module 1532 and module 2534. It can be appreciated that memory 530 may include any number of memory modules. An example of memory 530 may be dynamic random access memory (DRAM).


Display 540 may be any device that displays information to a user. Examples may include an LCD screen, CRT monitor, or seven-segment display.


Computer-readable medium 550 may be any magnetic, electronic, optical, or other computer-readable storage medium. Computer-readable storage medium 550 includes monitoring module 552, detection module 554, forwarding module 556, and encryption module 558. Computer-readable storage medium 550 may comprise any combination of volatile and/or non-volatile memory such as, for example, buffer memory, RAM, DRAM, ROM, flash, or any other suitable memory device, alone or in combination with other data storage devices.


Monitoring module 552 is configured to monitor data communicated over a bus. For example, monitoring module 552 may monitor data communicated over peripheral bus 460 (FIG. 4) between peripheral device 410 (FIG. 4) and client device 420. In some embodiments, monitoring module 552 may monitor data on the peripheral bus 460 (FIG. 4) using a snooping mechanism. The snooping mechanism may passively monitor all data communications over the peripheral bus 460 (FIG. 4).


Detection module 554 is configured to determine that the data monitored by monitoring module 552 is in fact communicated between the peripheral device 410 (FIG. 4) and the client device 420. For example, peripheral bus 410 may be shared between client device 420 and other peripheral devices (not shown) other than peripheral device 410 (FIG. 4). Detection module 554 may detect data communications over peripheral bus 460 (FIG. 4) that originate from peripheral device 410 (FIG. 4) and are destined for client device 420, or vice versa. In some embodiments, the snooping mechanism described above may also be employed by the detection module 554 for the determination. In some embodiments, detection module 554 may also determine the type of peripheral device 410 (FIG. 4) connected to the client device 420 and generate a identifier identifying the peripheral device 410 (FIG. 4).


Forwarding module 556 may be configured to send the data determined by detection module 554 in an unaltered form, along with an identifier identifying the peripheral device, to a cloud server, wherein the data is operable to be received by a device driver executing on the cloud server. The forwarding module may send the data over the network 430 (FIG. 4). It can be appreciated that no modifications may be made to the content of the data prior to sending, besides compression and/or encryption of the data that do not alter the data when it may be decompressed and/or decrypted. That is, the receiving device driver may ultimately receive a bit-for-bit representation of the determined data.


Encryption module 558 is configured to encrypt the data prior to the sending by the forwarding module 556. The data may be encrypted using any known encryption method, such as the advanced encryption standard (AES). In some embodiments, the encryption module 556 may also compress the data prior to the sending by the forwarding module 556. The compression and encryption of the raw data packets may result in bandwidth savings on network and increased security in the data transmission. Upon decompression and/or decryption, the raw data packets may be reconstructed bit-for-bit.



FIG. 5B is a block diagram of a server 440, according to embodiments of the present invention. Server 440 includes a processor 510, input device 520, memory 530, display 540, and computer-readable medium 550.

Input device 520 may be any device that accepts input from a user. Examples may include a keyboard, keypad, or mouse. In some embodiments, a multi-touch pad may be an input device.


Memory 530 may be any magnetic, electronic, or optical memory. Memory 260 includes two memory modules, module 1532 and module 2534. It can be appreciated that memory 530 may include any number of memory modules. An example of memory 530 may be dynamic random access memory (DRAM).


Display 540 may be any device that displays information to a user. Examples may include an LCD screen, CRT monitor, or seven-segment display.

Computer-readable storage medium 550 may comprise any combination of volatile and/or non-volatile memory such as, for example, buffer memory, RAM, DRAM, ROM, flash, or any other suitable memory device, alone or in combination with other data storage devices.


Receiving module 553 is configured to receive data in an unaltered form and an identifier identifying the peripheral device 410 (FIG. 4), wherein the unaltered data is a forwarded communication between the peripheral device (FIG. 4) and the client device 420 (FIG. 4). In some embodiments, the received data is the data sent from the client device 420 (FIG. 4) as described in FIG. 5A. Receiving module 553 may receive the data over network 430 (FIG. 4).


Enabling module 555 is configured to enable a device driver based on the received identifier. As described above, the received identifier may identify the type of peripheral device 410 (FIG. 4). The identifier may include information about the peripheral device 410 (FIG. 4) such as manufacturer, platform, model, or other pertinent information required for operation of the peripheral device 410 (FIG. 4). Based on the received identifier, the enabling module 555 may enable a device driver specific to the peripheral device 410 (FIG. 4). For example, if peripheral device 410 (FIG. 4) is a gaming pad, enabling module 555 may enable a specific gaming pad device driver on server 440.


Execution module 557 is configured to execute one or more commands via the device driver, based on the received data. In some embodiments, execution module 557 may translate the received data to a format understandable by processor 510 and processor 510 may in turn execute the data. For example, if the received data is a keystroke, based on input by the user using peripheral device 410 (FIG. 4), the enabling module 555 may enable a device driver for an input device and execution module 557 may execute the keystroke on server 440, as intended by the user.


Decryption module 559 is configured to decrypt the encrypted data, by encryption module 558 (FIG. 5A) prior to the receiving by the receiving module. The data may be decrypted using any known decryption method, such as the advanced encryption standard (AES). In some embodiments, the decryption module 559 may also decompress the data prior to the receiving by the receiving module 553.


In some embodiments, a forwarding module may be configured to send responsive data back to the client device. The responsive data may be in response to the commands executed by execution module 557. The client device may then forward the responsive data to the peripheral device. An example of responsive data may include, but is not limited to, an acknowledgment signal or an updated cursor position.



FIG. 6 is a block diagram of a peripheral device 410 communicatively coupled with a client device 420 and also a cloud-based server 610, according to embodiments of the present invention. In some embodiments, cloud-based server 610 may be similar to server 440 of FIG. 4. In some embodiments, peripheral device 410 may be a gaming input device, e.g., a joystick, steering wheel, gamepad, etc.


The peripheral device 410 may be communicatively coupled with the cloud-based server 440 through a network 430, for example, through wired or wireless interfaces. In some embodiments, the network 430 may be wide area network (WAN) or a local area network (LAN).


The cloud-based server 610 may be part of a cloud-based computing system. Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). Therefore, the cloud-based server 610 may be remotely located from the peripheral device 410. For example, the cloud-based server 610 may be located in a separate building or city as the peripheral device 410.


In some cases, at least some of the functionality of peripheral device 410 may not be compatible with client device 420. For example, the peripheral device 410 may require use of certain device drivers that the client device 420 does not or cannot support. Alternatively, the client device 420 may not support the use of peripheral device 410 because peripheral device 410 requires heavier processing power than the client device 420 may be able to provide. Or, the peripheral device 410 may not be supported by client device 420 because the client device 410 is not compatible with the client device 420 for various reasons, e.g., the peripheral device 420 may be designed for a different platform or operating system than the one running on client device 420, thereby not allowing communication between the peripheral device 410 and client device 420.


Importantly, the cloud-based server 610 may be operable to interpret and execute commands sent by peripheral device 410. For example, the cloud-based server 610 may provide a compatible platform or operating system, may provide the necessary processing power, or may be able to communicate with the client device 420 to execute the peripheral device 410 commands. Accordingly, the device drivers for peripheral device 420 may already exist on cloud-based server 610 or may be downloaded from the Internet, installed on the cloud-based server 610, and enabled on the cloud-based server 610. For example, the cloud-based server 980 may download, install, and enable device drivers for peripheral device 410 such that peripheral device 410 may be used to play a game on client device 420 (where, in some embodiments, cloud-based server 610 also provides the game and gaming resources to client device 420).


Further, the client device 420 may receive data from the cloud-based server 610 related to or representing the game. For example, the cloud-based server 610 may send video, audio, and/or other data related to the gaming content through the network 430 to the client device 420. The other data may include, for example, instructions to activate a force feedback vibration component in the peripheral device 410.


In one example, the cloud-based server 610 may execute a software application requiring graphics and audio processing. The cloud-based server 610 may then transmit the graphics and audio to the client device 420 for display and playback. Accordingly, the client device 420 may provide the gaming content to a user of the client device 420 with the aid of the cloud-based server 610 that the gaming console may not have otherwise been able to provide. Even if the client device 420 may have been able to provide the gaming content, it may be able to do so at a lower quality or with limitations, but the cloud-based server 610 may be capable of providing higher quality and limitation-free gaming content generation to the client device 420.


The video, audio, and/or other data transmitted from the cloud-based server 610 may or may not be compressed before sending, and decompressed and/or decoded when received by the client device 420. For example, see copending U.S. patent application Ser. No. 13/727,357, “VIRTUALIZED GRAPHICS PROCESSING FOR REMOTE DISPLAY,” filed Dec. 26, 2012, which is incorporated herein by reference for all purposes. For example, the cloud-based server 610 may compress the data into H.264 format for transmittal to the client device 420. Once the client device 420 receives the data to be displayed, it may decompress and display the video, audio, and/or other data.


The client device 420 may be operable to send user inputs to the cloud-based server 610 via peripheral device 410. For example, the client device 420 may send data representing user interaction with the physical controls, touchscreen, internal/external motion tracking components, and so on of peripheral device 410, to the cloud-based server 610. In this way, a user may control software applications or content that is being executed on the cloud-based server 610. The client device 420 may send user inputs through the network 430.


Because the cloud-based server 610 may be remotely communicatively coupled with the client device 420, the client device 420 may be able to send/receive data from the cloud-based server 610 while at different locations. For example, the client device 420 may be able to send/receive data from the cloud-based server 610 while at different homes, outdoors, or even while located in different countries. Accordingly, a user of the client device 420 may be free to travel between different locations and continue to benefit from the services of the cloud-based server 610.


The various embodiments discussed with respect to other figures may be used with the cloud-based server 610. For example, there may be more than one client device.


It can be appreciated that the cloud-based server 610 may provide applications to client device 420 other than gaming. For example, cloud-based server 610 may provide professional applications to client device 420 such as, but not limited to, visual computing applications, computer aided design applications, imaging applications, etc. The use of these professional applications in a cloud-based environment may share the same benefits as those described with respect to gaming applications above. Additionally, an employer providing these professional applications may realize cost savings by not requiring to purchase expensive workstation computers with the processing power required to run powerful professional applications. Instead, employees may simply use a lower cost client device 420 to access the professional applications residing on the cloud-based server 610. Further, the client device 420 may be any platform, e.g. Mac OS, Linux, Windows, etc., allowing employees to use the platform they are the most comfortable with.



FIG. 7 depicts a flowchart 700 of an exemplary computer-implemented process sending unaltered data between a client device and peripheral device to a cloud-based server, according to an embodiment of the present invention. While the various steps in this flowchart are presented and described sequentially, one of ordinary skill will appreciate that some or all of the steps can be executed in different orders and some or all of the steps can be executed in parallel. Further, in one or more embodiments of the invention, one or more of the steps described below can be omitted, repeated, and/or performed in a different order. Accordingly, the specific arrangement of steps shown in FIG. 7 should not be construed as limiting the scope of the invention. Rather, it will be apparent to persons skilled in the relevant art(s) from the teachings provided herein that other functional flows are within the scope and spirit of the present invention. Flowchart 700 may be described with continued reference to exemplary embodiments described above, though the method is not limited to those embodiments.


In block 702, data communicated over a bus is monitored. In some embodiments, the bus may be a peripheral bus between a client device and a peripheral device. The bus may conform to a standard, such as USB or FireWire. The data may be monitored by employing a snooping mechanism on the bus. The snooping mechanism may not alter any data on the bus, but simply view all data that is communicated over the bus. For example, in FIG. 4, the data communicated on the peripheral bus, between the peripheral device and client device, is monitored.


In block 704, a determination is made whether the data is communicated between a peripheral device and a client device. In some embodiments, the determination may be made based on the monitoring of data using the snooping mechanism. The peripheral bus may experience data communication from devices other than the peripheral device and client device. For example, in FIG. 4, a determination is made whether the data communicated on the peripheral bus is communicated between the peripheral device and the client device.


In block 706, the data is sent in an unaltered form, along with an identifier identifying the peripheral device, to a cloud server. The data is operable to be received by a device driver executing on the cloud server. The identifier may be generated based on the determination in block 704. The identifier may include information such as manufacturer, type of device, platform, etc. The data may be sent to the cloud server in an unaltered form, that is, in its raw bit format. For example, in FIG. 3, the unaltered data and an identifier are sent from the client device to the server over the network. In some embodiments, the data may be encrypted prior to being sent to the server.



FIG. 8 depicts a flowchart 800 of an exemplary computer-implemented process of sending unaltered data between a client device and peripheral device to a cloud-based server, according to an embodiment of the present invention. While the various steps in this flowchart are presented and described sequentially, one of ordinary skill will appreciate that some or all of the steps can be executed in different orders and some or all of the steps can be executed in parallel. Further, in one or more embodiments of the invention, one or more of the steps described below can be omitted, repeated, and/or performed in a different order. Accordingly, the specific arrangement of steps shown in FIG. 8 should not be construed as limiting the scope of the invention. Rather, it will be apparent to persons skilled in the relevant art(s) from the teachings provided herein that other functional flows are within the scope and spirit of the present invention. Flowchart 800 may be described with continued reference to exemplary embodiments described above, though the method is not limited to those embodiments.


In block 802, data is received in an unaltered form along with an identifier identifying a peripheral device. The unaltered data is a forwarded communication between the peripheral device and the client device. In some embodiments, the data is decrypted upon being received. For example, in FIG. 4, the unaltered data and identifier sent by the client device, via the network, is received by the server.


In block 804, a device driver for the peripheral device is enabled. The device driver may be enabled based on the received identifier and unaltered data. For example, in FIG. 4, a device driver is enabled on the server based on the received identifier and unaltered data. If the identifier indicates that the input device is a peripheral device, the device driver for that specific device driver may be enabled.


In block 806, based on the received data, one or more commands are executed using the device driver. The commands may be executed using an execution module on the server device. For example, in FIG. 4, the server executes commands based on the received data.


In some embodiments, audio and video data associated with the executed commands are sent to the client device. For example, if the received data were data packets for a movie, the associated audio and video reconstructed from the data packets may be sent to the client device. The client device may display and play the video/audio through local resources such as a display screen and speakers.
