Hardware capabilities of mobile devices, such as smartphones and tablets, have improved to the point where it is feasible to seamlessly deliver a virtual desktop of a remote computing system to such devices. Such capabilities are currently provided, for example, by the Citrix Workspace app for iOS. An external monitor may also be connected to a mobile device to permit such a delivered virtual desktop to be mirrored with or extended onto the external monitor. One or more external user interface devices, e.g., a keyboard, a mouse, a trackpad, etc., may additionally be connected to the mobile device to facilitate user interaction with the displayed virtual desktop.
The inventors have recognized and appreciated that simply mirroring or extending the delivered virtual desktop to an external monitor of a mobile device, while providing some significant benefits, does not take full advantage of the smaller, built-in touchscreen of the mobile device. In particular, the inventors have identified a number of challenges faced by users when interacting with a virtual desktop, and have devised of a number of beneficial uses for the touchscreen of a mobile device that, if employed in parallel with the presentation of a virtual desktop on one or more external monitors, can markedly improve the user's experience interacting with the virtual desktop.
One challenge the inventors identified is that, even where the virtual desktop is displayed on a larger, external monitor, it can be difficult and/or cumbersome for a user to locate particular files and/or applications the user wants to access or launch. To access a specific application, a user will typically need to click on or otherwise select the “start” menu and search through a long list of available applications, or else hunt through a collection of shortcut icons on the desktop. Likewise, to locate a particular file, a user will typically need to visually scan through file icons on the virtual desktop, or navigate amongst various folders accessible via the virtual desktop, to track down the desired file. These processes can be made even more difficult when a user's virtual desktop is cluttered or poorly organized.
Another challenge the inventors identified is that it can be difficult and/or cumbersome to keep track of notifications from applications that are running within the remote computing environment that is hosting the delivered virtual desktop. It is common for a user to have a large number of application windows open simultaneously within a virtual desktop, but for the user's attention to be focused on just one window at a time. In such circumstances, it is not uncommon for users to miss or ignore at least some notifications from running applications. While it may be possible for the user to open a separate notification management window (e.g., by selecting a particular task bar icon) to view previously sent notifications, it can be difficult and/or cumbersome for users to navigate to and/or interact with such a notification management window. For this reason, it is not uncommon for unread application notifications to “stack up” via a hidden, background process, with the issues that prompted such notifications not being addressed, and/or with the notifications never being viewed.
Offered is a system in which a mobile device (e.g., a computing device with a touchscreen) can provide additional user interface (UI) functionality for a remote computing environment that improves the user experience by supplementing the UI of the delivered virtual desktop for that environment. An example implementation of such a system 100 is shown in
In some implementations, the remote computing system 104 may include a shared computing resource 502 of the type described in connection with
As indicated by an arrow 114 in
In some implementations, the content for the delivered desktop (per the arrow 108) and the data for the desktop (per the arrow 114) may be communicated over respective communication channels established between the mobile device 102 and the remote computing system 104. As explained in more detail in Section G, for example, in some implementations, one or more virtual channels may be established (e.g., as independent computing architecture (ICA) virtual channels) between respective drivers (e.g., virtual drivers 702) of a resource access application 524 of the mobile device 102 and corresponding engines 704 of the resource delivery agent 504 of the shared computing resource 502. In other implementations, other types of communication channels (e.g., different time slots, different frequency channels, different code division multiple access (CDMA) channels, etc.) may additionally or alternatively be employed to communicate the content for the delivered desktop (per the arrow 108) and the data for the desktop (per the arrow 114), respectively. As such, a user may view a virtual desktop for a remote computing environment within the window 112 of the external monitor(s) 106 and may interact with one or more applications presented within that delivered desktop via one or more components 118 and/or via UI controls presented in a portion of the touchscreen 116.
Advantageously, rather than utilizing the mobile device 102 simply to display some or all of the delivered virtual desktop, and possibly enabling user input with respect to that virtual desktop (e.g., to input keystrokes or control a cursor), the system 100 may be configured to enable the touchscreen 116 to present additional UI functionality (e.g., by displaying additional UI content 122) for the remote computing environment that is being delivered to the mobile device 102, thus enabling a user of the mobile device 102 to interact with the delivered computing environment in new and beneficial ways.
Several examples of such additional UI content 122a-c that may be presented on the touchscreen 116 are described below in connection with
Referring now to
As shown in
In response to the selection of an application icon 126 on the touchscreen 116, if the corresponding application has not yet been launched on the remote computing system 104, the system 100 may cause the application to be launched and presented within a new window of the virtual desktop that is being delivered to the mobile device 102 and displayed on the external monitor(s) 106. For example, in some implementations, the selected application may be launched on a shared computing resource 502 (described in Section E) that is hosting the virtual desktop being delivered to the mobile device 102. If, on the other hand, the application corresponding to a selected application icon 126 has already been launched on the remote computing system 104 (e.g., a shared computing resource 502), the system 100 may instead cause an existing window for that application to be un-minimized, maximized, and/or brought to the foreground of the virtual desktop that is being delivered to the mobile device 102 and displayed on the external monitor(s) 106. Such control of the window for the selected resource may be accomplished, for example, by sending an appropriate instruction to a component of the resource delivery agent 504 (described in Section E) that is overseeing delivery of the content for virtual desktop to the mobile device 102. Accordingly, this technique may greatly facilitate a user's ability to quickly access or switch to a desired application within the virtual desktop, regardless of the number of application windows the user currently has open and/or the current state (maximized, minimized, or set size) of those windows.
As shown in
In response to the selection of a file UI element 130 on the touchscreen 116, if the application needed to access the corresponding file has not yet been launched on the remote computing system 104, the system 100 may cause the application to be launched and used to open the selected file within a new window of the virtual desktop that is being delivered to the mobile device 102 and displayed on the external monitor(s) 106. For example, in some implementations, the requisite application may be launched on a shared computing resource 502 (described in Section E) that is hosting the virtual desktop being delivered to the mobile device 102. If, on the other hand, the application needed to open the selected file has already been launched on the remote computing system 104, the system 100 may instead simply cause the file to be opened within a new window for that application within the delivered virtual desktop. In some implementations, for example, a component of the resource delivery agent 504 (described in Section E) that is overseeing delivery of the content for virtual desktop to the mobile device 102 may be instructed to open the selected file within a new window. Accordingly, this technique may greatly facilitate a user's ability to quickly access a desired file within the virtual desktop.
As shown in
In response to the selection of a notification element 134 on the touchscreen 116, the system 100 may cause a window for the application responsible for the notification to be opened and/or brought to the foreground within the virtual desktop that is being delivered to the mobile device 102 and displayed on the external monitor(s) 106. For instance, if a selected notification element 134 was generated based on a new message received by a messaging application, the window for that messaging application may be brought to the foreground of the virtual desktop and/or or the newly-received message may be opened in a new window on the virtual desktop. Such control of a window for an application responsible for a selected notification may be accomplished, for example, by sending an appropriate instruction to a component of the resource delivery agent 504 (described in Section E) that is overseeing delivery of the content for virtual desktop to the mobile device 102.

In some embodiments, one or more of the appliances 208, 212 may be implemented as products sold by Citrix Systems, Inc., of Fort Lauderdale, Fla., such as Citrix SD-WAN™ or Citrix Cloud™. For example, in some implementations, one or more of the appliances 208, 212 may be cloud connectors that enable communications to be exchanged between resources within a cloud computing environment and resources outside such an environment, e.g., resources hosted within a data center of+ an organization.
The processor(s) 302 may be implemented by one or more programmable processors executing one or more computer programs to perform the functions of the system. As used herein, the term “processor” describes an electronic circuit that performs a function, an operation, or a sequence of operations. The function, operation, or sequence of operations may be hard coded into the electronic circuit or soft coded by way of instructions held in a memory device. A “processor” may perform the function, operation, or sequence of operations using digital values or using analog signals. In some embodiments, the “processor” can be embodied in one or more application specific integrated circuits (ASICs), microprocessors, digital signal processors, microcontrollers, field programmable gate arrays (FPGAs), programmable logic arrays (PLAs), multi-core processors, or general-purpose computers with associated memory. The “processor” may be analog, digital or mixed-signal. In some embodiments, the “processor” may be one or more physical processors or one or more “virtual” (e.g., remotely located or “cloud”) processors.

In the cloud computing environment 400, one or more clients 202 (such as those described in connection with
In some embodiments, a gateway appliance(s) or service may be utilized to provide access to cloud computing resources and virtual sessions. By way of example, Citrix Gateway, provided by Citrix Systems, Inc., may be deployed on-premises or on public clouds to provide users with secure access and single sign-on to virtual, SaaS and web applications. Furthermore, to protect users from web threats, a gateway such as Citrix Secure Web Gateway may be used. Citrix Secure Web Gateway uses a cloud-based service and a local cache to check for URL reputation and category.
In still further embodiments, the cloud computing environment 400 may provide a hybrid cloud that is a combination of a public cloud and one or more resources located outside such a cloud, such as resources hosted within one or more data centers of an organization. Public clouds may include public servers that are maintained by third parties to the clients 202 or the enterprise/tenant. The servers may be located off-site in remote geographical locations or otherwise. In some implementations, one or more cloud connectors may be used to facilitate the exchange of communications between one more resources within the cloud computing environment 400 and one or more resources outside of such an environment.
The cloud computing environment 400 can provide resource pooling to serve multiple users via clients 202 through a multi-tenant environment or multi-tenant model with different physical and virtual resources dynamically assigned and reassigned responsive to different demands within the respective environment. The multi-tenant environment can include a system or architecture that can provide a single instance of software, an application or a software application to serve multiple users. In some embodiments, the cloud computing environment 400 can provide on-demand self-service to unilaterally provision computing capabilities (e.g., server time, network storage) across a network for multiple clients 202. By way of example, provisioning services may be provided through a system such as Citrix Provisioning Services (Citrix PVS). Citrix PVS is a software-streaming technology that delivers patches, updates, and other configuration information to multiple virtual desktop endpoints through a shared desktop image. The cloud computing environment 400 can provide an elasticity to dynamically scale out or scale in response to different demands from one or more clients 202. In some embodiments, the cloud computing environment 400 may include or provide monitoring services to monitor, control and/or generate reports corresponding to the provided shared services and resources.
In some embodiments, the cloud computing environment 400 may provide cloud-based delivery of different types of cloud computing services, such as Software as a service (SaaS) 402, Platform as a Service (PaaS) 404, Infrastructure as a Service (IaaS) 406, and Desktop as a Service (DaaS) 408, for example. IaaS may refer to a user renting the use of infrastructure resources that are needed during a specified time period. IaaS providers may offer storage, networking, servers or virtualization resources from large pools, allowing the users to quickly scale up by accessing more resources as needed. Examples of IaaS platforms include AMAZON WEB SERVICES provided by Amazon.com, Inc., of Seattle, Wash., Azure IaaS provided by Microsoft Corporation or Redmond, Wash., RACKSPACE CLOUD provided by Rackspace US, Inc., of San Antonio, Tex., Google Compute Engine provided by Google Inc. of Mountain View, Calif., and RIGHTSCALE provided by RightScale, Inc., of Santa Barbara, Calif.
PaaS providers may offer functionality provided by IaaS, including, e.g., storage, networking, servers or virtualization, as well as additional resources such as, e.g., the operating system, middleware, or runtime resources. Examples of PaaS include WINDOWS AZURE provided by Microsoft Corporation of Redmond, Wash., Google App Engine provided by Google Inc., and HEROKU provided by Heroku, Inc. of San Francisco, Calif.
SaaS providers may offer the resources that PaaS provides, including storage, networking, servers, virtualization, operating system, middleware, or runtime resources. In some embodiments, SaaS providers may offer additional resources including, e.g., data and application resources. Examples of SaaS include GOOGLE APPS provided by Google Inc., SALESFORCE provided by Salesforce.com Inc. of San Francisco, Calif., or OFFICE 365 provided by Microsoft Corporation. Examples of SaaS may also include data storage providers, e.g. Citrix ShareFile® from Citrix Systems, DROPBOX provided by Dropbox, Inc. of San Francisco, Calif., Microsoft SKYDRIVE provided by Microsoft Corporation, Google Drive provided by Google Inc., or Apple ICLOUD provided by Apple Inc. of Cupertino, Calif.
Similar to SaaS, DaaS (which is also known as hosted desktop services) is a form of virtual desktop infrastructure (VDI) in which virtual desktop sessions are typically delivered as a cloud service along with the apps used on the virtual desktop. Citrix Cloud from Citrix Systems is one example of a DaaS delivery platform. DaaS delivery platforms may be hosted on a public cloud computing infrastructure, such as AZURE CLOUD from Microsoft Corporation of Redmond, Wash., or AMAZON WEB SERVICES provided by Amazon.com, Inc., of Seattle, Wash., for example. In the case of Citrix Cloud, Citrix Workspace app may be used as a single-entry point for bringing apps, files and desktops together (whether on-premises or in the cloud) to deliver a unified experience.
E. Systems and Methods for Delivering Virtualized Applications and/or Desktops to Client Devices
The resource delivery system 500 shown in
As shown in
The resource delivery controller(s) 512 may be the central management component of the resource delivery system 500. In some implementations, the resource delivery controller(s) 512 may be installed on at least one server in a data center of an organization. The Delivery Controller of the Citrix Virtual Apps and Desktops™ system offered by Citrix Systems, Inc., of Fort Lauderdale, Fla., is one example implementation of the resource delivery controller(s) 512. For reliability and availability, respective resource delivery controllers 512 may be installed on multiple servers. The resource delivery controller(s) 512 may communicate with the shared computing resources 502 to distribute applications and/or desktops, authenticate and manage user access, broker connections between client devices 202 and resource delivery agents 504 running on respective shared computing resources 502, optimize use connections, and/or load-balance use connections. As described in more detail below, a broker service 532 (shown in
The resource delivery controller(s) 512 may manage the state of desktops, starting and stopping them based on demand and administrative configuration. In some implementations, the resource delivery controller(s) 512 may also enable the adjustment of user profiles (stored within the database(s) 520) to manage user personalization settings in virtualized or physical Windows environments.
In some implementations, the database(s) 520 may include at least one Microsoft Structured Query Language (SQL) Server database in which configuration and session information may be stored. As noted above, the database(s) 520 may store the data collected and managed by the services that make up the resource delivery controller(s) 512. In some implementations, the database(s) 520 may be provided within a data center of an organization and may have a persistent connection to the resource delivery controller(s) 512. Although not illustrated in
The resource delivery agents 504 may be installed on physical or virtual machines that are made available to deliver applications or desktops to users. The resource delivery agents 504 may enable such machines to register with the resource delivery controller(s) 512. The registration of a machine with the resource delivery controller(s) 512 may cause that machine and the resources it is hosting to be made available to users. The resource delivery agents 504 may establish and manage the connections between the machines on which they are installed and client devices 202. The resource delivery agents 504 may also verify that a license is available for the user and/or session, and may apply policies that are configured for the session.
The resource delivery agents 504 may communicate session information to the broker service 532 (shown in
When users connect from outside one or more corporate firewalls, e.g., firewalls 526a and 526b shown in
The client access manager 510 of the resource delivery system 500 may authenticate users and manage stores of desktops and/or applications that are available for users to access. In some implementations, the client access manager 510 may provide an application “storefront” for an enterprise, which may provide users with self-service access to the desktops and/or applications that the enterprise opts to make available to them. In some implementations, the client access manager 510 may also keep track of users' application subscriptions, shortcut names, and other data. Tracking such data may, for example, help ensure that users have a consistent experience across multiple devices.
As shown in
In some embodiments, the resource access application 524 may intercept network communications from a network stack used by the one or more applications. For example, the resource access application 524 may intercept a network communication at any point in a network stack and redirect the network communication to a destination desired, managed, and/or controlled by the resource access application 524, for example, to intercept and redirect a transport layer connection to an IP address and port controlled and/or managed by resource access application 524. The resource access application 524 may thus, in some embodiments, transparently intercept any protocol layer below the transport layer, such as the network layer, and any protocol layer above the transport layer, such as the session, presentation, or application layers. The resource access application 524 may, for example, interface with the transport layer to secure, optimize, accelerate, route, and/or load-balance any communications provided via any protocol carried by the transport layer.
In some embodiments, the resource access application 524 may be implemented as an Independent Computing Architecture (ICA) client developed by Citrix Systems, Inc. The resource access application 524 may perform acceleration, streaming, monitoring, and/or other operations. For example, the resource access application 524 may accelerate streaming an application from a shared computing resource 502 running a resource delivery agent 504 to the client device 202. The resource access application 524 may also perform endpoint detection/scanning and/or collect endpoint information about the client 202. For example, the resource access application 524 may identify and determine one or more client-side attributes, such as: the operating system and/or a version of an operating system, a service pack of the operating system, a running service, a running process, a file, presence or versions of various applications of the client, such as antivirus, firewall, security, and/or other software.
The resource manager 514 shown in
The resource director 516 may, for example, be a web-based tool that enables IT support and help desk teams to monitor an environment, troubleshoot issues before they become system-critical, and perform support tasks for end users. The Director component of the Citrix Virtual Apps and Desktops™ system offered by Citrix Systems, Inc., of Fort Lauderdale, Fla., is one example implementation of the resource director 516. In some implementations, a single deployment of the resource director 516 may be used to connect to and monitor multiple resource delivery systems 500, such as that shown in
The license manager 518, as its name implies, may enable the management of licenses within the resource delivery system 500. In some implementations, the license manager 518 may communicate with the resource delivery controller(s) 512 to manage licensing for a user's session and with the resource manager 514 to allocate license files.
As noted above, in some implementations, the shared computing resources 502 shown in
Although not depicted in
The monitoring agents may, for example, monitor, measure, collect, and/or analyze data on a frequency (e.g., a predetermined frequency), based upon an occurrence of given event(s), or in real time during operation of the resource delivery system 500. The monitoring agents may, for example, monitor resource consumption and/or performance of hardware, software, and/or communications resources of the clients 202, the gateway 508 (and/or any other components in the DMZ 528), and/or the resource delivery controller(s) 512, the shared computing resources 502, the resource delivery agents 504, or any other components shown in
The monitoring agents may provide application performance management for the resource delivery system 500. For example, based upon one or more monitored performance conditions or metrics, the resource delivery system 500 may be dynamically adjusted, for example periodically or in real-time, to optimize application delivery by the resource delivery agents 504 to the clients 202 based upon network environment performance and conditions
In some embodiments, client devices 202 may not directly access the resource delivery controller 512. Instead, the resource delivery agent 504 and the client access manager 510 may serve as intermediaries between client devices 202 and the resource delivery controller 512. When users log on using the client access manager 510, their credentials may pass through to the broker service 532 on the resource delivery controller 512. The broker service 532 may then obtain profiles and available resources based on the policies set for them.
As indicated by arrow 536, the user's credentials may then move through this pathway to access the broker service 532 of resource delivery controller 512. In some implementations, such communications may be encrypted to protect the security of such credentials. The broker service 532 may determine which desktops and/or applications the user is allowed to access. After the credentials have been verified, information about available applications and/or desktops may be sent back to the client device 202 through the pathway between the client access manager 510 and the resource access application 524, as indicated by arrows 538, 540, and 541. The user of the client device 202 may thus be provided with a list of available applications and/or desktops. When the user selects an application or desktop from this list, an indication of the selected resource goes back down the previously described pathway to the resource delivery controller 512. The resource delivery controller 512 may then select an appropriate resource delivery agent 504 to host the selected applications or desktop.
As indicated by arrow 542, the resource delivery controller 512 may send a message to the selected resource delivery agent 504 with the user's credentials, and may then send pertinent data about the user and the connection to the resource delivery agent 504. The resource delivery agent 504 may then accept the connection and, as indicated by arrows 544, 538, 540, and 541, may send a set of access parameters (stored in an access parameter stack 546a) back through the same pathways to the resource access application 524. In particular, the set of access parameters may be collected by the client access manager 510 and then sent to the resource access application 524 where they may be stored as an access parameter file 546b. In some implementations, the access parameter file 546b may be created as part of a protocol conversation between the client access manager 510 and the resource access application 524. In other implementations, the client access manager 510 may convert the access parameters to the file 546b, and that file 546b may then be downloaded to the client device 202. In some implementations, the access parameters may remain encrypted throughout this process.
The access parameter file 546b that is then stored on the client device 202 may be used to establish a direct connection 548 between the client device 202 and the access parameter stack 546a running on the resource delivery agent 504. As illustrated, the connection 548 between the client device 202 and the resource delivery agent 504 may use a gateway protocol 550. In some implementations, the gateway protocol 550 may include a feature that enables the client device 202 to immediately reconnect to the resource delivery agent 504 if the connection 548 is lost, rather than having to relaunch through the management infrastructure (including the client access manager 510, the resource delivery controller 512, etc.).
After the client device 202 connects to the resource delivery agent 504, the resource delivery agent 504 may notify the resource delivery controller 512 that the user is logged on. The resource delivery controller 512 may then send this information to the database(s) 520 (shown in
Such sessions between client devices 202 and resource delivery agents 504 produce data that system administrators can access through the resource manager 514 and/or the resource director 516.
Within the resource delivery controller 512, the broker service 532 may report session data for every session on the machine providing real-time data. The monitor service 560 may also track the real-time data and store it as historical data in the database(s) 520. In some implementations, the resource manager 514 may communicate with the broker service 532 and may access real-time data. The resource director 516 may communicate with the broker service 532 to access the database(s) 520.
An example process for enabling the delivery of applications and/or desktops will now be described. First, the machines that are to deliver applications and/or desktops may be set up with “Machine Catalogs.” Then, “Delivery Groups” may be created that specify the applications and/or desktops that are to be made available (using machines in the Machine Catalogs), and which users can access them. In some implementations, “Application Groups” may also be created to manage collections of applications.
Machine Catalogs are collections of virtual or physical machines that can be managed as a single entity. These machines, and the application and/or virtual desktops on them, are the resources that may be made available to users. All the machines in a Machine Catalog may have the same operating system and the same resource delivery agent 504 installed. They may also have the same applications and/or virtual desktops.
In some implementations, a master image may be created and used to create identical virtual machines in the catalog. For virtual machines, the provisioning method may be specified for the machines in that catalog. Valid machine types may, for example, include “Multi-session OS,” “Single-session OS,” and “Remote PC access.” A Multi-session OS machine is a virtual or physical machine with a multi-session operating system. Such a machine may be used to deliver published applications (also known as server-based hosted applications) and published desktops (also known as server-hosted desktops). These machines may allow multiple users to connect to them at one time. A Single-session OS machine is a virtual or physical machine with a single-session operating system. Such a machine may be used to deliver Virtual Desktop Infrastructure (VDI) desktops (desktops running single-session OSs that can optionally be personalized), virtual machine (VM)-hosted apps (applications from single-session OSs), and hosted physical desktops. Only one user at a time can connect to each of these desktops. A Remote PC access machine may enable remote users to access their physical office PCs from any device running the resource access application 524.
Delivery Groups may specify which users can access which applications and/or desktops on which machines. Delivery Groups may include machines from the Machine Catalogs, and Active Directory users who have access to the Site. In some implementations, users may be assigned to Delivery Groups by their Active Directory group, because Active Directory groups and Delivery Groups are ways to group users with similar requirements.
Delivery Groups may contain machines from more than one Machine Catalog, and Machine Catalogs may contribute machines to more than one Delivery Group. In at least some implementations, however, individual machines can only belong to one Delivery Group at a time.
The specific resources that users in the Delivery Group can access may be defined. For example, to deliver different applications to different users, all of the applications may be installed on the master image for one Machine Catalog and enough machines may be created in that catalog to distribute among several Delivery Groups. Delivery Groups may then be configured to deliver a different subset of applications that are installed on the machines.
Application Groups may provide application management and resource control advantages over using more Delivery Groups. Using a “tag restriction” feature, existing machines may be used for more than one “publishing” task, saving the costs of deployment and managing additional machines. A tag restriction can be thought of as subdividing (or partitioning) the machines in a Delivery Group. Application Groups may also be helpful when isolating and troubleshooting a subset of machines in a Delivery Group.
“Tags” may be strings that identify items such as machines, applications, desktops, Delivery Groups, Application Groups, and policies. After creating a tag and adding it to an item, certain operations may be tailored to apply to only items that have a specified tag.
In some implementations, tags may be used to tailor search displays is the resource manager 514. For example, to display only applications that have been optimized for testers, a tag named “test” may be created and may then be added (applied) to those applications. A search performed by the resource manager 514 may then be filtered with the tag “test”.
In some implementations, tags may be used to “publish” applications from an Application Group or specific desktops from a Delivery Group, considering only a subset of the machines in selected Delivery Groups. Using an Application Group or desktops with a tag restriction may be helpful when isolating and troubleshooting a subset of machines in a Delivery Group.
In some implementations, tags may be used to schedule periodic restarts for a subset of machines in a Delivery Group. Using a tag restriction for machines may, for example, enable the use of new PowerShell cmdlets to configure multiple restart schedules for subsets of machines in a Delivery Group.
In some implementations, tags may be used to tailor the application (assignment) of particular policies to a subset of machines in Delivery Groups, Delivery Group types, or organizational units (OUs) of a Site that have (or do not have) a specified tag. For example, if a particular policy is to be applied only to the more powerful workstations, a tag named “high power” may be applied to those machines and the policy may be set to apply to only machines to which the high power tag has been applied. Tags may additionally or alternatively be applied to particular Delivery Groups and one or more policies may be set to apply only the Delivery Groups to which such tags have been applied.
In some embodiments, the resource manager 514 may be used to create or edit a tag restriction for a desktop in a shared Delivery Group or an Application Group. In some implementations, creating such a tag restriction may involve several steps. First, a tag may be created and then added (applied) to one or more machines. Second a group may be created or edited to include the tag restriction, thus restricting launches to machines with the applied tag. A tag restriction may extend the machine selection process of the broker service 532. In particular, the broker service 532 may select a machine from an associated Delivery Group subject to access policy, configured user lists, zone preference, and launch readiness, plus the tag restriction (if present). For applications, the broker service 532 may fall back to other Delivery Groups in priority order, applying the same machine selection rules for each considered Delivery Group.
In some implementations, tags may be created, added (applied), edited, and/or deleted from selected items using the resource manager 514. Tag restrictions may, for example, be configured when creating or editing desktops in Delivery Groups and/or when creating or editing Application Groups.
As noted above, the resource delivery system 500 described in connection with
In some implementations, one or more components of the resource delivery system 500 may be provided as a service within a cloud-based computing environment.
In addition to serving as a channel for communication between the cloud computing environment 572 and the resource location(s) 570, the cloud connectors 568 may enable cloud management without requiring any complex networking or infrastructure configuration such as virtual private networks (VPNs) or Internet Protocol Security (IPsec) tunnels.
As noted above, the resource delivery controller(s) 512 may serve as the central control layer component in a deployment. The resource delivery controller(s) 512 may communicate through the cloud connectors 568 in each resource location 570 to distribute applications and/or desktops, authenticate and manage user access, broker connections between users and their virtual desktops and/or applications, optimize use connections, and/or load-balance use connections. In some implementations, the resource delivery controller(s) 512 may additionally track which users are logged on and where, which session resources the users have, and if users need to reconnect to existing applications. The resource delivery controller(s) 512 may further manage the state of desktops, starting and stopping them based on demand and administrative configuration, in some implementations.
The configuration manager 574 in the cloud computing environment 572 may (A) enable administrators to specify which services are to be made available to users via the resource access application, (B) customize the uniform resource locator (URL) that the resource access application 524 is to use to access the available resources, (C) customize the appearance of the user interface provided by the resource access application, such as logos, color, and preferences, (D) specify how users are to authenticate to the system, such as using the Active Directory 522, and/or (E) specify external connectivity for the resource locations 570.
As noted above, a resource location 570 may include at least one cloud connector 568 that serves as the communications channel between the components in the cloud computing environment 572 and the components in the resource location 570. In the resource location 570, the cloud connector(s) may act as a proxy for the resource delivery controller(s) 512 in the cloud computing environment 572.
As noted above, the physical or virtual machines that deliver applications and/or desktops may include resource delivery agents 504a, 504b. The resource delivery agents 504 may register with at least one cloud connector 568. After registration, connections may be brokered from those resources to users. The resource delivery agents 504 may further establish and manage the connection between the machine and the client device 202, and apply policies that are configured for the session. The resource delivery agents 504 may communicate session information to the cloud connector 568 through the broker agent 556 (shown in
A host connection may be established that enables communication between components in the cloud computing environment 572 and the resource delivery agents 504 on the shared computing resources 502. Specifications for such host connections may include (A) the address and credentials to access the host, (B) the tool that is to be used to create VMs, (C) the storage method to use, (D) the machines to use for storage, and/or (E) which network the VMs will use.
The virtualization server 602 illustrated in
Executing on one or more of the physical processors 610 may be one or more virtual machines 620a-c (generally 620). The virtual machines 620 may have respective virtual disks 622a-c and virtual processors 624a-c. In some embodiments, a first virtual machine 620a may execute, using the virtual processor 624a, a control program 626 that includes a tools stack 628. The control program 626 may be referred to as a control virtual machine, Domain 0, Dom0, or other virtual machine used for system administration and/or control. In some embodiments, one or more of the virtual machines 620b-c may execute, using a virtual processor 624b-c, a guest operating system 630a-b (generally 630).
The physical devices 608 may include, for example, a network interface card, a video card, an input device (e.g., a keyboard, a mouse, a scanner, etc.), an output device (e.g., a monitor, a display device, speakers, a printer, etc.), a storage device (e.g., an optical drive), a Universal Serial Bus (USB) connection, a network element (e.g., router, firewall, network address translator, load balancer, virtual private network (VPN) gateway, Dynamic Host Configuration Protocol (DHCP) router, etc.), or any device connected to or communicating with virtualization server 602. The physical memory 612 in hardware layer 604 may include any type of memory. The physical memory 612 may store data, and in some embodiments may store one or more programs, or set of executable instructions.
The virtualization server 602 may also include hypervisor 618. In some embodiments, the hypervisor 618 may be a program executed by processors 610 on the virtualization server 602 to create and manage any number of virtual machines 620. The hypervisor 618 may be referred to as a virtual machine monitor, or platform virtualization software. In some embodiments, the hypervisor 618 may be any combination of executable instructions and hardware that monitors virtual machines 620 executing on a computing machine. The hypervisor 618 may be a Type 2 hypervisor, where the hypervisor executes within operating system 616 executing on virtualization server 602. The virtual machines may then execute at a layer above hypervisor 618. In some embodiments, the Type 2 hypervisor may execute within the context of a user's operating system such that the Type 2 hypervisor interacts with the user's operating system. In other embodiments, one or more virtualization servers 602 in a virtualization environment may instead include a Type 1 hypervisor (not shown). A Type 1 hypervisor may execute on the virtualization server 602 by directly accessing the hardware and resources within hardware layer 604. That is, while the Type 2 hypervisor 618 accesses system resources through host operating system 616, as shown, a Type 1 hypervisor may directly access all system resources without host operating system 616. A Type 1 hypervisor may execute directly on one or more physical processors 610 of the virtualization server 602, and may include program data stored in the physical memory 612.
The hypervisor 618, in some embodiments, may provide virtual resources to the guest operating systems 630 or control programs 626 executing on virtual machines 620 in any manner that simulates the operating systems 630 or control programs 626 having direct access to system resources. System resources may include, but are not limited to, the physical devices 608, the physical disks 606, the physical processors 610, physical memory 612, and any other component included in the hardware layer 604 of the virtualization server 602. The hypervisor 618 may be used to emulate virtual hardware, partition physical hardware, virtualize physical hardware, and/or execute virtual machines that provide access to computing environments. In still other embodiments, the hypervisor 618 may control processor scheduling and memory partitioning for the virtual machine 620 executing on the virtualization server 602. Examples of hypervisor 618 may include those manufactured by VMWare, Inc., of Palo Alto, Calif.; Xen Project® hypervisor, an open source product whose development is overseen by the open source XenProject.org community; Hyper-V®, Virtual Server®, and Virtual PC® hypervisors provided by Microsoft Corporation of Redmond, Wash.; or others. In some embodiments, the virtualization server 602 may execute a hypervisor 618 that creates a virtual machine platform on which the guest operating systems 630 may execute. In these embodiments, the virtualization server 602 may be referred to as a host server. An example of such a virtualization server is Citrix Hypervisor® provided by Citrix Systems, Inc., of Fort Lauderdale, Fla.
The hypervisor 618 may create one or more virtual machines 620b-c (generally 620) in which guest operating systems 630 execute. In some embodiments, the hypervisor 618 may load a virtual machine image to create a virtual machine 620. The virtual machine image may refer to a collection of data, states, instructions, etc. that make up an instance of a virtual machine. In other embodiments, the hypervisor 618 may execute guest operating system 630 within the virtual machine 620. In still other embodiments, the virtual machine 620 may execute the guest operating system 630.
In addition to creating the virtual machines 620, the hypervisor 618 may control the execution of at least one virtual machine 620. In other embodiments, the hypervisor 618 may present at least one virtual machine 620 with an abstraction of at least one hardware resource provided by the virtualization server 602 (e.g., any hardware resource available within hardware layer 604). In other embodiments, the hypervisor 618 may control the manner in which the virtual machines 620 access physical processors 610 available in the virtualization server 602. Controlling access to the physical processors 610 may include determining whether the virtual machine 620 should have access to the processor 610, and how physical processor capabilities are presented to the virtual machine 620.
As shown in
The virtual machines 620 may include respective virtual disks 622a-c (generally 622) and virtual processors 624a-c (generally 624.) The virtual disk 622, in some embodiments, may be a virtualized view of one or more physical disks 606 of the virtualization server 602, or a portion of one or more physical disks 606 of the virtualization server 602. The virtualized view of the physical disks 606 may be generated, provided, and managed by the hypervisor 618. In some embodiments, the hypervisor 618 may provide the virtual machines 620 with unique views of the physical disks 606. Thus, in these embodiments, a particular virtual disk 622 included in a respective virtual machine 620 may be unique when compared with other virtual disks 622.
The virtual processor 624 may be a virtualized view of one or more physical processors 610 of the virtualization server 602. In some embodiments, the virtualized view of physical processors 610 may be generated, provided, and managed by the hypervisor 618. In some embodiments, the virtual processor 624 may have substantially all of the same characteristics of at least one physical processor 610. In other embodiments, the virtual processor 610 may provide a modified view of the physical processors 610 such that at least some of the characteristics of the virtual processor 624 are different from the characteristics of the corresponding physical processor 610.
An example implementation of a system 100 for providing an improved user interface for a delivered virtual desktop was introduced above (in Section A) in connection with
As indicated by the arrow 706a in
In some implementations, the touchscreen UI engine 704c and the touchscreen UI virtual driver 702c may operate together to enable the use of the touchscreen 116 for supplemental UI features, such as those described above in connection with
In other implementations, the touchscreen UI engine 704c may itself generate data (e.g., graphics data) that is to be sent to the touchscreen driver 708c for display by the touchscreen 116, and may send that data to the touchscreen UI virtual driver 702c. In such implementations, the UI data that is communicated from the touchscreen UI virtual driver 702c to the touchscreen UI engine 704c may represent touch inputs that are detected by the touchscreen 116, and the touchscreen UI engine may be responsible for correlating those touch inputs with the graphics being displayed on the touchscreen 116 to determine intended user inputs.
As noted above, the sequence diagram 800 shown in
The resource access application 524 may send (804) a message to the resource delivery agent 504 indicating the number and type(s) of monitors that are to be used to display the virtual desktop for viewing by a user operating the mobile device 102. In some implementations, for example, available monitors may be detected by the resource access application 524 (e.g., by requesting such data from an operating system of the mobile device 102), and the message sent to the resource delivery agent 504 may identify such monitor(s). In some implementations, the resource access application 524 may additionally or alternatively provide a user interface to enable the user of the mobile device 102 to specify the monitors that are to be used to display the virtual desktop. As indicated, that message may indicate that one or more external monitors 106 are to be employed. Based on the received message, a component of the resource delivery agent 504 may generate (806) graphics for the virtual desktop that are formatted for display by the indicated type(s) of external monitor(s) 106, and the resource delivery agent 504 may send (808) data representing the generated desktop graphics to a component of the resource access application 524. As described above in connection with
As further shown in
Based on the touchscreen UI data received from the resource delivery agent 504, a component of the resource access application 524 (e.g., the touchscreen UI virtual driver 702c) may generate (814) data for an image to be presented by the touchscreen 116. In some implementations, for example, such data may be generated to cause the touchscreen 116 to display additional UI content 122, such as that described above in connection with
Upon viewing the additional UI content 122 on the touchscreen 116 (e.g., as shown in one of
When, at the decision step 902, the touchscreen UI virtual driver 702c determines that new touchscreen UI data has been received, the routine 900 may proceed to a step 904, at which the touchscreen UI virtual driver 702c may generate data (e.g., graphics data) corresponding to additional UI content 122 for the touchscreen 116, such as that described above in connection with
At a step 908 of the routine 900, the touchscreen UI virtual driver 702c may send the generated data (e.g., graphics data) to the touchscreen driver 708c, so as to cause the touchscreen 116 to display the additional UI content 122. The step 908 may correspond, for example to the step 816 of the sequence diagram 800 shown in
Following the step 908, the routine 900 may proceed to a decision step 910, at which the touchscreen UI virtual driver 702c may determine whether a touchscreen UI element corresponding to a managed resource (e.g., an application icon 126, a file UI element 130, or a notification element 134) has been selected. Such a determination may be made for example based on data (e.g., touchscreen input data) received from the touchscreen driver 708c, e.g., per the step 820 of the sequence diagram 800 shown in
Although not illustrated in
At the decision step 906, the touchscreen UI virtual driver 702c may determine whether a touchscreen UI element impacting the presentation of the additional UI content 122 (e.g., a tab 124, a folder 128, a checkbox for sorting or filtering, etc.) has been selected. The identify of selected touchscreen UI elements may be determined, for example, by comparing the coordinates on the touchscreen 116 where touches occur to the coordinates on the touchscreen 116 at which the touchscreen UI elements are displayed. When, at the decision step 906, the touchscreen UI virtual driver 702c determines that such a presentation-related UI element has been selected, the routine 900 may proceed to the step 904 (described above), at which new graphics for the additional UI content 122 may be generated to reflect the new presentation option. When, on the other hand, the touchscreen UI virtual driver 702c determines that such a presentation-related UI element has not been selected, the routine 900 may instead proceed to the decision step 910 (described above).
At a step 1004 of the routine 1000, the touchscreen UI engine 704c may identify the applications that have been installed in the remote computing environment being delivered to the mobile device 102, and that can thus be selectively accessed via the virtual desktop being displayed on the external monitor(s) 106. In some implementations, such applications may be identified by querying a registry of an operating system of the remote computing environment. For example, if the remote computing system is running a Microsoft Windows operating system, application names, paths, executable hashes, etc., for the to-be-listed applications may be generated and/or updated by searching the registry key “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall.” In some implementations, the identity of accessible applications may additionally or alternatively be determined by monitoring Windows processing launching events.
At a step 1006 of the routine 1000, the touchscreen UI engine 704c may assign and/or adjust values (to be used for sorting and/or filtering) to the applications that were identified at the step 1004. In some implementations, for example, applications may be assigned values indicating the frequency at which they have historically been accessed via the virtual desktop. Additionally or alternatively, applications may be assigned values indicating when they were last accessed. Such values may be used, for example, to determine whether and/or in what order indicators of applications are to appear when rendered on the touchscreen 116. For example, with reference to
Further, it should be appreciated that, in some implementations, sorting/filtering values need not be assigned to applications, and the resource access application 524 may instead be configured to allow the user of the mobile device 102 to select and move the application icons 126 to different locations on the touchscreen 116, to nest such icons within one or more folders 128, etc., similar to the manner in which users commonly manipulate icons for mobile applications on smartphones and tablets.
At a step 1008 of the routine 1000, the touchscreen UI engine 704c may identify the files that can be accessed by the remote computing environment being delivered to the mobile device 102, and that can thus be selectively accessed via the virtual desktop being displayed on the external monitor(s) 106. In some implementations, such files may be identified by reading registry keys for the applications identified at the step 1004 that are used to access files, e.g., MS Word, PowerPoint, Adobe, etc. As one example, recently opened files for Microsoft Office applications may, in some implementations, be identified by querying the registry key(s) at the path “C:\Users\AppData\Roaming\Microsoft\Office\Recent.”
At a step 1010 of the routine 1000, the touchscreen UI engine 704c may assign and/or adjust values (to be used for sorting and/or filtering) to the files that were identified at the step 1008. In some implementations, for example, files may be assigned values indicating the frequency at which they have historically been accessed via the virtual desktop. Additionally or alternatively, files may be assigned values indicating when they were last accessed, when they were last modified, when they were created, their name, their size, etc. Such values may be used, for example, to determine how to sort and/or filter the file UI elements 130 displayed on the touchscreen 116. As was described above in connection with
At a step 1012 of the routine 1000, the touchscreen UI engine 704c may identify notifications concerning events of some or all of applications identified at the step 1004. In some implementations, the manner in which such notifications are identified may depend on the types of applications that are being monitored. For some application types, an application programming interface (API) hooking technique may be used to identify new notifications. For instance, for certain applications, message notification APIs for those applications may be identified and used by the touchscreen UI engine 704c to set a hook for new notification messages. As one example, for MS Teams, a Citrix Metaframe API Hook (MFAHook), i.e., a Dynamic Link Library (DLL) process enabling Asynchronous Procedure Call (APC) API hooking, may be used to inspect notifications of an MS Teams application that is executing in the remote computing environment being delivered to the mobile device 102, and to identify notifications of that application that are to be sent to the touchscreen UI virtual driver 702c of the resources access application 524 on the mobile device 102 for presentation on the touchscreen 116, e.g., as one of the notification elements 134 shown in
For applications for which a plug-in mechanism is provided, a plugin may additionally or alternatively be installed in the application to detect and/or generate new notifications about the application's events. As one example, for MS Outlook, an outlook plugin may be installed to inspect newly-received emails and redirect notifications for such emails, or to generate and send new notifications concerning such emails, to the touchscreen UI engine 704c.
At a step 1014 of the routine 1000, the touchscreen UI engine 704c may assign and/or adjust values (to be used for sorting and/or filtering) to the notifications that were identified at the step 1012. In some implementations, for example, notifications may be assigned values indicating when they were created, whether they have been read by the user, the application to which they relate, the sender of a message to which the notification relates, etc. Such values may be used, for example, to determine how to sort and/or filter the notifications elements 134 displayed on the touchscreen 116. As was described above in connection with
At a step 1016, of the routine 1000, touchscreen UI engine 704c may send the data accumulated at the steps 1004, 1006, 1008, 1010, 1012, and 1014 to the touchscreen UI virtual driver 702c for use in presenting additional UI content 122 on the touchscreen 116, such as illustrated in
At a step 1022 of the routine 1018, the touchscreen UI engine 704c may process the indicated selection. The step 1022 may correspond, for example to the step 822 of the sequence diagram 800 shown in
Further, with reference to
And still further, with reference to
As noted above, the sequence diagram 1100 shown in
The resource access application 524 may send (1104) a message to the resource delivery agent 504 indicating the number and type(s) of monitors that are to be used to display the virtual desktop for viewing by a user operating the mobile device 102. In some implementations, for example, available monitors may be detected by the resource access application 524 (e.g., by requesting such data from an operating system of the mobile device 102), and the message sent to the resource delivery agent 504 may identify such monitor(s). In some implementations, the resource access application 524 may additionally or alternatively provide a user interface to enable the user of the mobile device 102 to specify the monitors that are to be used to display the virtual desktop. As indicated, the message send to the resource delivery agent 504 may indicate that one or more external monitors 106 are to be employed. Based on the received message, a component of the resource delivery agent 504 may generate (1106) data (e.g., graphics data) for the virtual desktop that are formatted for display by the indicated type(s) of external monitor(s) 106, and the resource delivery agent 504 may send (1108) data representing the generated desktop graphics to a component of the resource access application 524. As described above in connection with
As further shown in
Upon viewing the additional UI content 122 on the touchscreen 116 (e.g., as shown in one of
When, at the decision step 1206, the touchscreen UI virtual driver 702c determines that an input to the touchscreen 116 has been detected, the routine 1200 may proceed to a step 1208, at which the touchscreen UI virtual driver 702c may send an indication of the detected touchscreen input to a component of the resource delivery agent 504 (e.g., the touchscreen UI engine 704c) for processing. When, on the other hand, the touchscreen UI virtual driver 702c determines (at the decision step 1206) that a touchscreen input has not occurred, the routine 1200 may instead return to the decision step 1202, at which the touchscreen UI virtual driver 702c may again determine whether new data for the touchscreen 116 has been received from a component of the resource delivery agent 504 (e.g., the touchscreen UI engine 704c).
At a step 1304 of the routine 1300, the touchscreen UI engine 704c may assign and/or adjust values (to be used for sorting and/or filtering) to the applications that were identified at the step 1302. The manner in which the touchscreen UI engine 704 may go about assigning/adjust such values in some implementations is described above in connection with the step 1006 of the routine 1000 shown in
At a step 1306 of the routine 1300, the touchscreen UI engine 704c may generate data (e.g., graphics data) corresponding to additional UI content 122a for the touchscreen 116, such as that described above in connection with
At a step 1308 of the routine 1300, the touchscreen UI engine 704c may send the generated data (e.g., touchscreen graphics data) to a component of the resource access application 524 (e.g., the touchscreen UI virtual driver 702c). The step 1308 may correspond, for example to the step 1114 of the sequence diagram 1100 shown in
At a decision step 1310 of the routine 1300, the touchscreen UI engine 704c may await receipt of data (e.g., touchscreen input data) from a component of the resource access application 524 (e.g., the touchscreen UI virtual driver 702c). As discussed above in connection with the steps 1120 and 1122 of the sequence diagram 1100 shown in
When, at the decision step 1312, the touchscreen UI engine 704c determines that a tab 124 has been selected, the routine 1300 may proceed to decisions steps 1318, 1320, and 1322 to determine which tab 124 (e.g., the files tab 124b, the notifications tab 124c, or the applications tab 124a) was selected, and may then proceed as indicated to switch to or “refresh” the data for that tab and await further touchscreen inputs (per decisions step 1332 and 1348, or 1310).
When, at the decision step 1314, the touchscreen UI engine 704c determines that an application icon 126 has been selected, the routine 1300 may proceed a step 1316 at which the touchscreen UI engine 704c may take an appropriate action with respect to the corresponding application. In some implementations, if the corresponding application has not yet been launched on the remote computing system 104, the touchscreen UI engine 704c may cause the application to be launched and presented within a new window of the virtual desktop that is being delivered to the mobile device 102 and displayed on the external monitor(s) 106. If, on the other hand, the application corresponding to a selected application icon 126 has already been launched on the remote computing system 104, the touchscreen UI engine 704c may instead cause an existing window for that application to be un-minimized, maximized, and/or brought to the foreground of the virtual desktop that is being delivered to the mobile device 102 and displayed on the external monitor(s) 106.
When, pursuant to the decisions steps 1312 and 1314, the touchscreen UI engine 704c determines that the touchscreen UI input did not identify a tab 124 or an application icon 126, the routine 1300 may return to the step 1302, at which the data for the additional UI content 122a may be refreshed. When the data (detected per the decision step 1310) indicates that a new sorting/filtering option has been selected, that “refreshing” process may involve generating new data (e.g., graphics data) for the touchscreen 116 (at the step 1306) in accordance with that selection.
At a step 1324 of the routine 1300, the touchscreen UI engine 704c may identify the files that can be accessed by the remote computing environment being delivered to the mobile device 102, and that can thus be selectively accessed via the virtual desktop being displayed on the external monitor(s) 106. The manner in which the touchscreen UI engine 704 may go about identifying such files in some implementations is described above in connection with the step 1008 of the routine 1000 shown in
At a step 1326 of the routine 1300, the touchscreen UI engine 704c may assign and/or adjust values (to be used for sorting and/or filtering) to the files that were identified at the step 1324. The manner in which the touchscreen UI engine 704 may go about assigning/adjust such values in some implementations is described above in connection with the step 1010 of the routine 1000 shown in
At a step 1328 of the routine 1300, the touchscreen UI engine 704c may generate data (e.g., graphics data) corresponding to additional UI content 122b for the touchscreen 116, such as that described above in connection with
At a step 1330 of the routine 1300, the touchscreen UI engine 704c may send the generated data (e.g., touchscreen graphics data) to a component of the resource access application 524 (e.g., the touchscreen UI virtual driver 702c). The step 1330 may correspond, for example to the step 1114 of the sequence diagram 1100 shown in
At a decision step 1332 of the routine 1300, the touchscreen UI engine 704c may await receipt of data (e.g., touchscreen input data) from a component of the resource access application 524 (e.g., the touchscreen UI virtual driver 702c). As discussed above in connection with the steps 1120 and 1122 of the sequence diagram 1100 shown in
When, at the decision step 1334, the touchscreen UI engine 704c determines that a tab 124 has been selected, the routine 1300 may proceed to the decisions steps 1320, 1322, and 1318 to determine which tab 124 (e.g., the notifications tab 124c, the applications tab 124a, or the files tab 124b) was selected, and may then proceed as indicated to switch to or “refresh” the data for that tab and await further touchscreen inputs (per decisions step 1348, 1310, or 1332).
When, at the decision step 1336, the touchscreen UI engine 704c determines that a file UI element 130 has been selected, the routine 1300 may proceed a step 1338, at which the touchscreen UI engine 704c may take an appropriate action with respect to the corresponding file. In some implementations, for example, if the application needed to access the corresponding file has not yet been launched on the remote computing system 104, the touchscreen UI engine 704c may cause the application to be launched and used to open the selected file within a new window of the virtual desktop that is being delivered to the mobile device 102 and displayed on the external monitor(s) 106. If, on the other hand, the application needed to open the selected file has already been launched on the remote computing system 104, the touchscreen UI engine 704c may instead simply cause the file to be opened within a new window for that application within the delivered virtual desktop.
When, pursuant to the decisions steps 1334 and 1336, the touchscreen UI engine 704c determines that the touchscreen UI input did not identify a tab 124 or a file UI element 130, the routine 1300 may return to the step 1324, at which the data for the additional UI content 122b may be refreshed. When the data (detected per the decision step 1332) indicates that a new sorting/filtering option has been selected, that “refreshing” process may involve generating new data (e.g., graphics data) for the touchscreen 116 (at the step 1328) in accordance with that selection.
At a step 1340 of the routine 1300, the touchscreen UI engine 704c may identify may identify notifications concerning events of some or all of applications identified at the step 1302. The manner in which the touchscreen UI engine 704 may go about identifying such notifications in some implementations is described above in connection with the step 1012 of the routine 1000 shown in
At a step 1342 of the routine 1300, the touchscreen UI engine 704c may assign and/or adjust values (to be used for sorting and/or filtering) to the notifications that were identified at the step 1340. The manner in which the touchscreen UI engine 704 may go about assigning/adjust such values in some implementations is described above in connection with the step 1014 of the routine 1000 shown in
At a step 1344 of the routine 1300, the touchscreen UI engine 704c may generate datat (e.g., graphics data) corresponding to additional UI content 122c for the touchscreen 116, such as that described above in connection with
At a step 1346 of the routine 1300, the touchscreen UI engine 704c may send the generated data (e.g., touchscreen graphics data) to a component of the resource access application 524 (e.g., the touchscreen UI virtual driver 702c). The step 1346 may correspond, for example to the step 1114 of the sequence diagram 1100 shown in
At a decision step 1348 of the routine 1300, the touchscreen UI engine 704c may await receipt of data (e.g., touchscreen input data) from a component of the resource access application 524 (e.g., the touchscreen UI virtual driver 702c). As discussed above in connection with the steps 1120 and 1122 of the sequence diagram 1100 shown in
When, at the decision step 1350, the touchscreen UI engine 704c determines that a tab 124 has been selected, the routine 1300 may proceed to the decisions steps 1322, 1318, and 1320 to determine which tab 124 (e.g., the applications tab 124a, the files tab 124b, or the notifications tab 124c) was selected, and may then proceed as indicated to switch to or “refresh” the data for that tab and await further touchscreen inputs (per decisions step 1310, 1332, or 1348).
When, at the decision step 1352, the touchscreen UI engine 704c determines that a notification element 134 has been selected, the routine 1300 may proceed a step 1354, at which the touchscreen UI engine 704c may take an appropriate action with respect to the corresponding notification. In some implementations, for example, in response to determining that a notification element 134 on the touchscreen 116 has been selected, the touchscreen UI engine 704c may cause a window for the application responsible for the notification to be opened and/or brought to the foreground within the virtual desktop that is being delivered to the mobile device 102 and displayed on the external monitor(s) 106. For instance, if a selected notification element 134 was generated based on a new message received by a messaging application, the window for that messaging application may be brought to the foreground of the virtual desktop and/or or the newly-received message may be opened in a new window on the virtual desktop.
When, pursuant to the decisions steps 1350 and 1352, the touchscreen UI engine 704c determines that the touchscreen UI input did not identify a tab 124 or notification element 134, the routine 1300 may return to the step 1340, at which the data for the additional UI content 122c may be refreshed. When the data (detected per the decision step 1348) indicates that a new sorting/filtering option has been selected, that “refreshing” process may involve generating new data (e.g., graphics data) for the touchscreen 116 (at the step 1344) in accordance with that selection.
