Field of the Invention

The present invention relates generally to the field of data transfer and more particularly relates to a system, method and computer program product for injecting directly into a web browser commands and/or contents created on local desktop applications of a computer device, and vice-versa.

Background Art

In the Internet era, web browsers are the most used applications and the majority of users spend most of their computer time on the web. Single page web applications are applications that fit on a web page with the goal of providing a more fluid user experience akin to a desktop application. All the necessary code is retrieved with a single page load or the appropriate resources are dynamically loaded and added to the page as necessary, usually in response to user actions. Interaction with a single page application often involves dynamic communication with a web server behind the scenes. However, editing images, sounds, videos or multi-dimensional content is still a task best left to desktop applications.

In order to share on the Internet content produced locally, a user needs to upload it on a server. Uploading to a server any content, such as images, sounds, videos or 3D models, has a high cost in terms of time and computing. If a user wants to preview the content inside the web browser and then confirm the upload with a known regular approach, this takes a roundtrip that relies on the available bandwidth and the server load. Another alternative to share on the Internet a locally produced content is to transfer to the web browser the content as a graphic file. However, graphic files, namely those known as « .fbx, .obj, or .dae » files occupy huge space data that prevent using this solution. Yet another approach is to use a real time editor to adapt to the Internet web navigator, the locally produced content. However, such solution which requires specific skills to develop the mapping between the original content and the internet content, prevents using it by any non expert final user.

A proprietary technology developed by Microsoft Corporation which has been widely used for transferring data from an application to another application is the well known OLE for Object Linking and Embedding. This technique allows embedding and linking to documents and others objects using drag and drop and clipboard operations. However, this technology is limited to transfer data to only Internet Explorer® and nowadays is no more supported as being open to security problems and being often the cause of unwanted windows and malware.

Then there is a need for a system and a method which overcome the limitations of the prior art and allowing direct injection into web browsers of any multidimensional content created locally on desktop applications. The present invention offers a solution to this need.

Summary of the invention

Detailed description of the invention

Embodiments of the invention are generally directed to systems, methods, and computer program products for handling content in computer devices. The term 'content' as used in the description is to be indifferently understood as data or commands, as well as multi-dimensional content. With reference to FIG. 1 , an operating environment 100 may include one or more computer devices 10 coupled to a network 20. The network 20 may include one or more private and/or public networks, e.g. the Internet, enabling communication and exchange of data with one or more distant servers 30. The distant server 30 may be coupled to storage servers 40 to store and retrieve data from the computer devices 10. The storage servers 40 may be servers of the type "cloud server" allowing storing data in the so-called cloud. The local computer device 10 shows the main components to operate the present invention. The local computer device includes at least one processor 102 and a memory 104 coupled to the at least one processor 102. The memory 104 may represent a random access memory (RAM) as well as any supplemental levels of memory, e.g., cache memories, non-volatile or backup memories (e.g., programmable or flash memories), read-only memories, etc. In addition, memory 104 may be considered to include memory storage physically, e.g., any cache memory in a microprocessor, as well as any storage capacity used as a virtual memory, e.g., as stored on a mass storage device or on another computer coupled to the local computer device 10.

For interface with a user or operator, the local computer device 10 may include a user interface 1 10 incorporating one or more user input/output devices, e.g., a keyboard, a pointing device, a display, a printer, etc. Otherwise, data may be communicated to and from another computer over a network interface 106 coupled to the communication network 20. The local computer device 10 also may be in communication with one or more mass storage devices, which may be, for example, internal hard disk storage devices, external hard disk storage devices, external databases, storage area network devices, etc. The local computer device 10 typically operates under the control of an operating system 108 and executes or otherwise relies upon various computer software applications, components, programs, objects, modules, engines, data structures, etc. In particular, the components may include a local native application 1 12, a local data injection component 1 1 6, a local web application browser 1 14, and may comprise instructions that may be resident and/or stored in the memory 104. For example, the local native application may be the known Google Sketch Up® application or the Blender® application or the Autodesk Revit® and the local web browser may be Firefox®, Internet Explorer®, Safari® or Google Chrome® to name a few. It is underlined that in the multi-dimensional content handling process of the present invention, both the native application and the web browser are executed locally without the need for a distant or remote server. The multi-dimensional content data transfer is executed between the local native application 1 12 and the local web browser 1 14 with a direct software-to-software communication through the local data injection component 1 1 6. In one embodiment this direct communication is performed using a WebSocket protocol as defined in the Request for Comment RFC6455 provided by the Internet Engineering Task Force (IETF). Embodiments of the invention leverage the benefits of a websocket full-duplex communication connection 1 15 as further detailed with reference to figures 6 and 7. The local computer device 10 may also include one or more databases including, for example, a multi-dimensional record database 1 18. The multidimensional record database 1 18 may comprise data and supporting data structures that store and organize multi-dimensional data. In an embodiment, data is encoded in JSON language or alternatively in binary and compressed in the "gzip" format. The database 1 18 may be arranged with any database organization and/or structure including, but not limited to, a relational database, a hierarchical database, a network database, and/or combinations thereof. A database management system in the form of a computer software application executing as instructions on the processing unit of the local computer device 10 may be used to access information or data stored as records of the multi-dimensional record database 1 1 8.

Moreover, various applications, components, programs, objects, modules, engines etc. may also execute on one or more processors in another computer coupled to the local computer device 10 via the communication network 20, e.g., in a distributed or client-server computing environment, whereby the processing required to implement the functions of a computer program may be allocated to multiple computers over a network. For example, some of the functionality described herein as being incorporated into the local computer device 10 may be implemented in one or more servers. Consistent with embodiments of the invention, the modules, applications, components and/or engines may be executing on one or more servers and may cause the processor 102 to perform operations consistent with embodiments of the invention.

Figure 2 is a flow chart for a setup process in accordance with an embodiment of the present invention. The process begins 202 when a user request installation on the local computer device 10 of system tray application 204. The setup process allows determining (206, 210) if a local native application is already installed on the local computer device, and to install (208, 212) then the respective local data injection component. In an embodiment, the local data injection component is in the form of a desktop software application enhanced with a plug-in that is activated through the system tray application when a multi-dimensional content transfer is requested. Figure 3 is a flow chart for a process performed at the local computer device 10 of handling a multi-dimensional content request in accordance with an embodiment of the present invention. A data transfer request 302 is received. The data transfer query may comprise multi-dimensional data and/or commands to transfer data generated from a local native application to a local web browser. The commands may be any kind of commands such as to change a display mode or to disable a function for example.

Next, at step 304, the local data injection component associated to the local native application may access locally the data to be transferred. In a next step 306, the process allows determining if a user is authenticated in the system tray application. If yes, the process goes to a next step 31 6, otherwise if not, the process allows displaying an authentication page in the web browser 308 and sending an authentication request to a distant web application server 310. When the authentication is performed successfully 312, the local system tray application is notified 314, allowing the process to continue 31 6.

On step 31 6, after authentication of the user, the process allows the local data injection component to execute the query and to have the data be sent directly to the local web browser 1 14. The user then may have the data be displayed on a web browser user interface of the local computer device. In an embodiment, the execution of the data transfer query comprises the data extraction from the local native application by the local injection component and data encapsulation before the transfer.

Patent application titled "System, method and computer program product for automatic optimization of 3d textured models for network transfer and real-time rendering" filed the same day by the Applicant provides a detailed description of various embodiments for the extraction and preparation of data for the direct transfer of the present invention. In one embodiment, the preparation of data comprises a simplification operation of a 3D model, performed by using predefined heuristics. Preferably, the simplification is associated with a plurality of simplified versions of the 3D model, each simplified version being associated with a predefined level of detail. It is to be appreciated that the present invention allows a direct injection of data created with a local application into a local web application in few steps without, as for prior art, the need to have a transfer of data via a distant server or the need of a local disk transfer. Once the content is available on the local web application 31 6, the process allows handling any cross platform data changes 318, as detailed now with reference to figure 4.

On a step 402, a notification from the local web application informs the system tray application of an upcoming event. On a next step 404, the process allows determining the nature of the notification to determine if it is a data transfer or a data alteration or a command. If the notification relies on a data transfer, the data is simply transferred and the process ends (406). In any other cases, if it's data alteration or command, these latters are dispatched to the related applications (408).

The method of the present invention further allows the web browser communicating 320 a publishing command to a distant server to have the data be stored in a distant storage server such as in a Cloud storage 322. The process may end when the data are transferred from the local web browser on the local computer device to the remote cloud storage server.

Figure 5a illustrates a 3D content created with a local native application, while figure 5b illustrates the same 3D content after transfer into the local web browser. Advantageously, the automatic and direct transfer according to the process of the invention allows an original 3D model to be transferred into a web environment in few seconds.

It is to be appreciated that the original scene on figure 5a is created with a local 3D native application within a static environment, such as with Google Sketch Up®, whereas the final scene on figure 5b contains the same model as the original one but displayed in real time in a web navigator in a dynamic environment.

As shown on the left of figure 5b, advantageously the web navigator offers a plurality of tools and functions (510) to enrich, modify, complete the environment around the original 3D model. Figure 6 shows the components installed on a client computer device 10 to operate the process of figure 7. It is appreciated that reference numbers for components similar as those shown on figure 1 are identical. Steps of process 700 allows for a direct transfer of an original content created on client computer device 10 with a local application 1 12 into a local web application 1 14. For ease of description, the original content is a 3D model comprising a plurality of objects of various form, size and texture, such as the one shown on the example of figure 5a.

On a first step 702, the multi dimensional data of the 3D model are parsed through a local parsing plugin 602. Each data of the 3D model is extracted (point coordinates (x,y,z), textures coordinates (u,v), triangles (a,b,c) list, material list, nodes scenes coordinates, scales, rotations and material) and stored by respective address in the computer memory 104.

On a next step 704, the computer memory is read and the appropriate data are put in a data buffer coupled to the local data injection component 1 1 6. ^* Next on step 706, the bytes stored in the buffer are sent one by one as passing messages to the local data injection component 1 1 6. In a preferred implementation, the bytes are sent by Windows Messages (Microsoft Corporation). The bytes are read and optimize by applying decimation and compression algorithms, and a binary-to-text conversion is applied to the optimized data to obtain textual formatted data. In a preferred implementation, the optimized data are encoded into the well-known Base64 text format.

On a next step 708, the textual data are sent to the web browser 1 14 using a full-duplex communication protocol. In a preferred embodiment, a WebRTC like protocol is used for the direct ant real-time transfer. A websocket connection 1 15 is established between the data injection component 1 1 6 and the web browser 1 14 of the client computer and maintain active during the whole transfer.

In a variant, a sub-process allows checking on a regular basis that the websocket connection is still active otherwise the transfer is resumed.

On next step 710, the process allows decoding and converting the text formatted data into binary data. Advantageously, the Base64 data are sliced calling HTML chunk functions 604 allowing the decode and convert operations to be applied to chunk data.

Next step 712 of the process is the rendering of the converted data using a webplayer plugin 606 allowing real-time 3D display in the web browser 1 14 of the client computer device 10 as shown on figure 5b. The user is then able to navigate in real-time within the web browser.

Steps 714, 71 6 and 718 are shown as optional steps to illustrate the option of sending the real-time 3D model to a distant server 30.

When a user requests to share and publish a real-time 3D model on the internet (branch Yes of step 714), the process allows the websocket full-duplex connection to send (71 6) HTML publishing message to the data injection component 1 1 6 to have the 3D data be sent (718) to a remote server through HTTP REST services.

The present invention is particularly of interest for any commercial domain where interactive models are required to evaluate their impact into a specific real time environment, such in urbanism, architecture, design, interior design, industrial prototype, storyboard, crime scene reconstruction, education, or wedding reception planning.
