Description

Title of the invention: Methods for assisting in the sharing of multimedia elements and feedback, electronic devices, systems, computer program products and corresponding media 1. Technical Domain

[0001] The present application relates to the field of telecommunications and more specifically to the field of information sharing between users of at least one electronic device. It concerns in particular a method for assisting in sharing and a method for reporting perceptions, implemented respectively by one or more electronic devices, as well as the corresponding electronic devices, computer program products and recording media. 2. State of the art

[0002] The use of electronic means to share information between individuals is becoming increasingly widespread. The information shared can be diverse. For example, it can be audio (voice, for instance), textual, or graphical, or a combination of at least two of these types of information. Thus, it can involve sharing textual or graphic material, supplemented by audio commentary (particularly from a presenter of that material).

[0003] The perception of information shared during these communications may vary among individuals, which may impair the quality of communication.

[0004] The purpose of this application is to propose improvements to at least some of the drawbacks of the prior art. 3. Description of the invention

[0005] The present application aims to improve the situation by means of a method for assisting in the sharing of a multimedia element, said method comprising: - obtaining at least part of a multimedia element intended to be shared by a first user of a first electronic device to at least two second users of second electronic devices, said second users being distinct from said first user; - a provision, intended for said first user, of at least one piece of information representative of a perception of one or more portion(s) of said multimedia element by at least one of said second users.

[0006] In certain embodiments, said representative information may, for example, be information that does not allow the said second users to be distinguished from each other.

[0007] In certain embodiments, said representative information may, for example, be anonymized information.

[0008] Depending on the embodiment, this can be synchronous sharing (during a teleconference for example) or asynchronous sharing (by emails, or via storage in a shared space).

[0009] The multimedia element can be an audio, text, image, video element, or a combination of such elements.

[0010] The first device may be, for example, a terminal, a gateway, or a server.

[0011] It should be noted that the method can be implemented in embodiments where the first and / or second users use (at different times, for example) the same device (the terms "first device" and / or "second devices" then referring to the same device). In such embodiments, the multimedia element can, for example, be a multimedia element made available by the first user in a storage space of the device and accessible for writing to the first user and for reading to the second users.

[0012] In at least some embodiments, said method includes providing said first user with a designation of said portion of said multimedia element.

[0013] In at least some embodiments, said representative information takes into account knowledge, by said at least one second user, of at least one audiovisual item present in said portion of said multimedia element.

[0014] In at least some embodiments, said representative information takes into account at least one perception indication received from at least one of said second devices via a communication interface of said first device.

[0015] In at least some embodiments, said provision of said representative information is implemented prior to a sharing of said multimedia element between said first device and said second devices.

[0016] Such embodiments can, for example, provide assistance during the creation (construction) of a multimedia element, when the first user is the creator of the multimedia element and already knows, when creating the multimedia element, which "second" users (among others) this multimedia element is intended for.

[0017] In at least some embodiments, said provision of said representative information is implemented during a synchronous sharing of said multimedia element by said first and second devices, prior to, and / or during, rendering of said portion of said multimedia element.

[0018] Embodiments in which the representational perception information is provided just before or during the rendering of the portion of said multimedia element to which it relates can, for example, help the first user (sharing the multimedia element) to accompany this sharing with personalized explanations, taking into account this representational information. For example, such embodiments can help a first user, presenting a multimedia element such as a slideshow, to adapt an oral presentation of the relevant portion of the multimedia element based on the representational information provided to them (by providing more detailed explanations or, conversely, by limiting their explanations, for example, during the presentation of the relevant portion).Implementation methods where representative perception information is provided slightly before the rendering of the portion to which it relates can, for example, help the first user to adapt their explanations in advance (for example, to anticipate difficulties in understanding). Thus, more detailed explanations than planned on certain points before the rendering of the relevant portion can allow a second user with whom the multimedia element is shared to better understand that portion when it is rendered.

[0019] In at least some embodiments, said supply is implemented after the rendering of said portion of said multimedia element.

[0020] Such embodiments can allow a first user sharing the multimedia element to obtain feedback on the shared portion, so as to be able to react to this feedback, for example by providing additional explanations "after the fact".

[0021] In at least some embodiments, the method includes a detection of said audiovisual item in said portion of said multimedia element and said perception indication is received in response to a transmission to said second devices of said audiovisual item.

[0022] In at least some embodiments, said detection of said audiovisual item and / or said sending of said audiovisual item are carried out continuously during said acquisition of said multimedia element.

[0023] In at least some embodiments, said process is implemented by a support service accessible after subscription to the first user.

[0024] According to another aspect, the present application relates to a method of transmitting, to a first electronic device, a perception relating to a multimedia element, said method being implemented by a second electronic device and comprising: - obtaining at least a partial at least one multimedia element; - A provision, in said first electronic device, of at least one indication of the perception of one or more portion(s) of said element multimedia by a second user of said second device, said perception indication being obtained automatically by said second device.

[0025] The said perception indication can, for example, be obtained without specific action from said second user.

[0026] In at least some embodiments, said provision of said perception indication is implemented prior to a sharing of said multimedia element by a first user of said first device with said second user of said second device.

[0027] In at least some embodiments, said provision of said perception indication is implemented during a synchronous sharing of said multimedia element by said first and second devices, prior to, and / or during, rendering of said portion of said multimedia element.

[0028] In at least some embodiments, said audiovisual item is obtained by analyzing said multimedia element.

[0029] In at least some embodiments, said analysis of said multimedia element is carried out as said multimedia element is obtained.

[0030] In at least some embodiments, said portion of said multimedia element comprises at least one audiovisual item and where said perception indication is representative of a presence, or respectively an absence, of said audiovisual item in a knowledge base associated with said second user.

[0031] In at least some embodiments, it may be a database grouping words well known, respectively poorly known, to the second user.

[0032] In at least some embodiments, said portion of said multimedia element includes at least one audiovisual item and said perception indication takes into account a designation of said audiovisual item via a user interface of said second device.

[0033] In at least some embodiments, said process is implemented by a support service accessible after subscription of said second user of said second device.

[0034] The features, presented in isolation in this application in connection with certain embodiments of at least one of the processes of this application may be combined with each other according to other embodiments of this process.

[0035] According to another aspect, the present application also relates to an electronic device adapted to implement at least one of the methods of the present application in any of its embodiments.

[0036] For example, the present application thus relates to a first electronic device comprising at least one processor configured to assist in sharing a multimedia element, said assistance comprising: - obtaining at least part of a multimedia element intended to be shared by a first user of said first electronic device to at least two second users of second electronic devices, said second users being distinct from said first user; - a provision, intended for said first user, of at least one piece of information representative of a perception of one or more portion(s) of said multimedia element by at least one of said second users.

[0037] In certain embodiments, said representative information may be information that does not allow said second users to be distinguished from each other, such as anonymized information.

[0038] For example, the present application thus relates to a second electronic device comprising at least one processor configured for transmitting, to a first electronic device, a perception relating to a multimedia element, said transmission comprising: - at least partial acquisition of at least one multimedia element; - A provision, to said first electronic device, of at least one indication of perception of one or more portion(s) of said multimedia element by a second user of said second device, said indication of perception being obtained automatically by said second device.

[0039] According to another aspect, the present application also relates to a telecommunications system comprising at least a first electronic device adapted to implement the assistance method of the present application in any of its embodiments and at least a second electronic device adapted to implement the collection method of the present application in any of its embodiments.

[0040] Thus, the present application relates, for example, to a telecommunications system comprising at least one first electronic device and at least one second electronic device, said at least one first electronic device comprising at least one processor configured for assisting in the sharing of a multimedia element, said assisting comprising: - obtaining at least part of a multimedia element intended to be shared by a first user of said first electronic device to at least two second users of said second electronic device, said second users being distinct from said first user; - a provision, intended for said first user, of at least one piece of information representative of a perception of one or more portion(s) of said multimedia element by at least one of said second users;

[0041] And said at least a second electronic device comprising at least one processor configured for transmitting, to said first electronic device, a perception relating to said multimedia element, said transmission comprising: - obtaining at least partial access to said at least one multimedia element; - A provision, to said first electronic device, of at least one indication of perception of one or more portion(s) of said multimedia element by a second user of said second device, said indication of perception being obtained automatically by said second device.

[0042] In certain embodiments, said representative information may be information that does not allow said second users to be distinguished from each other, such as anonymized information.

[0043] The present application also relates to a computer program comprising instructions for the implementation of at least one embodiment of at least one of the above methods, when the program is executed by a processor and a recording (or information) medium readable by an electronic device and on which the computer program is recorded.

[0044] For example, the present application thus relates to a computer program comprising instructions for implementing, when the program is executed by a processor of a first electronic device, a method for assisting in the sharing of a multimedia element, said assistance comprising: - obtaining at least part of a multimedia element intended to be shared by a first user of said first electronic device to at least two second users of a second electronic device, said second users being distinct from said first user; - a provision, intended for said first user, of at least one piece of information representative of a perception of one or more portion(s) of said multimedia element by at least one of said second users.

[0045] In certain embodiments, said representative information may be information that does not allow said second users to be distinguished from each other, such as anonymized information.

[0046] This application also relates, for example, to a computer program comprising instructions for implementing, when the program is executed by a processor of a second electronic device, a method for transmitting, to a first electronic device, a perception relating to a multimedia element, said method comprising: - at least partial acquisition of at least one multimedia element; - A provision, in said first electronic device, of at least one indication of the perception of one or more portion(s) of said element multimedia by a second user of said second device, said perception indication being obtained automatically by said second device.

[0047] For example, the present application also relates to a processor-readable information carrier of a first electronic device on which is recorded a computer program comprising instructions for implementing, when the program is executed by the processor, a method for assisting in the sharing of a multimedia element, said assistance comprising: - obtaining at least part of a multimedia element intended to be shared by a first user of said first electronic device to at least two second users of a second electronic device, said second users being distinct from said first user; - a provision, intended for said first user, of at least one piece of information representative of a perception of one or more portion(s) of said multimedia element by at least one of said second users.

[0048] In certain embodiments, said representative information may be information that does not allow said second users to be distinguished from each other, such as anonymized information.

[0049] The present application also relates, for example, to a recording medium readable by a processor of a second electronic device and on which is recorded a computer program comprising instructions for the implementation, when the program is executed by the processor, of a method of transmitting, to a first electronic device, a perception relating to a multimedia element, said method being implemented by a second electronic device and comprising: - at least partial acquisition of at least one multimedia element; - Provision, to said first electronic device, of at least one indication of perception of one or more portion(s) of said multimedia element by a second user of said second device, said indication of perception being obtained automatically by said second device.

[0050] The programs mentioned above may use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0051] The information (or recording) media referred to in this application may be any entity or device capable of storing the program. For example, a medium may include a storage means, such as a ROM, for example a CD-ROM or a microelectronic circuit ROM, or a magnetic recording means.

[0052] Such a means of storage can, for example, be a hard drive, a flash memory, etc.

[0053] On the other hand, an information medium can be a transmissible medium such as an electrical or optical signal, which can be transmitted via an electrical or optical cable, by radio, or by other means. A program according to the invention can, in particular, be downloaded onto an Internet-type network.

[0054] Alternatively, an information (or recording) medium may be an integrated circuit in which a program is incorporated, the circuit being adapted to execute or to be used in the execution of any of the embodiments of at least one of the methods that are the subject of this patent application.

[0055] Generally speaking, in the present application, obtaining an information element means, for example, receiving that information element from a communication network, and / or acquiring that information element (via, for example, user interface elements and / or sensors), and / or creating that information element by various processing means such as copying, and / or encoding, and / or decoding, and / or transformation, etc., and / or accessing that information element from a local or remote storage medium accessible to at least one device implementing, at least partially, this obtaining.

[0056] Generally speaking, the provision of an information element means in this application, for example, a transmission of that information element (possibly preceded by a copy, and / or a transformation and / or an encoding) over a communication network, and / or a rendering of that information element via output user interface elements, and / or a recording of that information element on a local or remote storage medium accessible to at least one device implementing, at least partially, that provision. 4.

[0066] Figure 5 presents an overview of a chronogram in a joint implementation of the sharing assistance and perception feedback processes of this application, in some of their embodiments. 5. Description of embodiments

[0067] This application aims to assist a first user, producer, or presenter of a multimedia element (such as content or an audiovisual stream) in obtaining feedback on that multimedia element. The feedback may relate to the perception of the multimedia element by at least one of the individuals with whom the first user wishes to share, or is currently sharing, that multimedia element. These individuals are also referred to in the application as (potential or actual) consumers of the multimedia element and as "second" users (to distinguish them from the first user sharing the multimedia element). This feedback may, in particular, help the first user to assess the relevance of the multimedia element to be shared with regard to the second users.

[0068] The feedback can for example be provided to the first user in the form of representative perception information, forming for example a synthesis of at least some of the individual feedback from the second users.

[0069] According to embodiments, feedback can be provided to the first user in real time (while building or viewing a multimedia element for future sharing, or while sharing it) or in delayed time (after this building, viewing or sharing).

[0070] Depending on the communication tools and the multimedia element used, sharing can be carried out synchronously (for example, during a teleconference) between the first and second users or asynchronously (for example, by sharing a text file via email). For example, it could simply involve the first user making this multimedia element available to the second user(s).

[0071] Such a solution may be particularly interesting in situations where the first user does not know (or knows little) the second users.

[0072] For example, during a videoconference, a participant sharing a document (e.g., a text presentation) with the other participants and commenting on it (orally, for example) can obtain, in real time, thanks to the solution described in this application, feedback on how these other participants perceive certain passages of the document. This feedback could include, for example, information relating to their level of understanding, their level of agreement or disagreement, and / or their level of interest in certain passages of the document.

[0073] The solution makes it possible in particular to inform the presenter (first user) of the terms of the document which are little known or poorly known to his audience (second users), so as to allow him to adapt his speech accordingly (for example to explain acronyms, reformulate a sentence etc).

[0074] Similarly, the solution can also allow the presenter to get feedback on some of his comments, so as for example to be able to recall or rephrase an explanation that was misunderstood by some participants.

[0075] Such a solution can find applications in particular in cases where the commentator does not have the possibility of viewing the faces of the participants (and therefore of instinctively assessing their reactions to his speech).

[0076] The present application is now described in more detail in relation to [Fig.1].

[0077] Figure 1 represents a telecommunications system 100 in which certain embodiments of the invention can be implemented. The system 100 comprises one or more electronic devices, at least some of which can communicate with each other via one or more communication networks 180, 182, optionally interconnected (for example, via an interconnection device 170 (also called a gateway), such as a local area network (LAN) and / or a wide area network (WAN). Examples of networks may include a corporate or home LAN and / or a WAN such as the internet, cellular, GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System), Wi-Fi, etc.

[0078] The electronic devices of the system 100 can be diverse: they can be, for example, terminals 110, 120, 130, 190 (such as a laptop, a smartphone, a smart TV and / or a tablet) as illustrated in [Fig. 1], augmented, mixed or virtual reality headsets 140, connected objects, and / or server(s), for example an application server 160, including a teleconferencing application (such as a videoconferencing server), a storage device 150. The system may also include network management and / or interconnection elements (not shown). These electronic devices can be associated with at least one user 112, 114, 116, 122, 132, 142, 192, (for example through a user account accessible by login), some of the electronic devices 120 being able to be associated with the same user 122, some of the electronic devices 110 being able to be shared by several users 112, 114, 116 (these devices 110 being for example likely to be used by different users at different times).

[0079] At least some of the devices of system 100 are capable of being used by their respective users for sharing (within the same device or between devices) at least one multimedia element.

[0080] This multimedia element can be of various types. For example, it can have at least one audio, image, video and / or text component or a combination of such components. It can be content already stored in memory in its entirety (such as a slideshow), or an element (stream) that is being constructed (or broadcast).

[0081] Figure 2 illustrates a simplified structure of an electronic device 200 of the system 100, adapted to implement the principles of the present application. Depending on the embodiment, it may be a server (for example, the server 160 of Figure 1), and / or a terminal (for example, one of the terminals 110, 120, 130, 140 and 190 of Figure 1).

[0082] The device 200 includes, in particular, at least one memory M 210. The device 200 may include, in particular, a buffer memory, volatile memory, for example of the RAM (Random Access Memory) type, and / or non-volatile memory (for example of the ROM (Read Only Memory) type). The device 200 may also include a processing unit UT 220, equipped, for example, with at least one processor P 222, and driven by a computer program PG 212 stored in memory M 210. At initialization, the code instructions of the computer program PG are, for example, loaded into RAM before being executed by the processor P.Said at least one processor P 222 of the processing unit UT 220 may in particular implement, individually or collectively, any one of the embodiments of at least one of the assistance and / or retrieval methods of this application (described respectively in relation to Figures 3A and 3B in particular), according to the instructions of the computer program PG. .

[0083] The device may also include, or be coupled to, at least one LO 230 input / output module, such as a communication module, allowing, for example, the device 200 to communicate with other devices in the system 100, via wired or wireless communication interfaces, and / or such as an interface module with a user of the device (also referred to more simply in this application as "user interface").

[0084] The user interface of the device means, for example, an interface integrated into the device 200, or a part of a third-party device connected to this device by wired or wireless means. For example, it could be a secondary screen of the device, a camera (enabling the acquisition of gesture commands from an operator, for example), or loudspeakers connected wirelessly to the device.

[0085] A user interface may in particular be an "output" user interface adapted for rendering (or controlling a rendering) of an output element of a computer application used by the device 200, for example an application running at least partially on the device 200 or an "online" application running at least partially remotely, for example on the server 160 of the system 100. Examples of output user interfaces of the device include one or more screens, in particular at least one graphics screen (touchscreen for example), one or more speakers, a connected headset (in particular an augmented, mixed or virtual reality headset).

[0086] By rendering, we mean here a display (or "output" according to English terminology) on at least one user interface, in any form whatsoever, for example including textual, audio, image, and / or video components, or a combination of such components.

[0087] Furthermore, a user interface can be a user interface, referred to as an "input" user interface, adapted for capturing an action or reaction from a user of the device 200 (in particular an action such as a command, or a reaction such as a movement, a physical or verbal expression, etc.). This may include an action or reaction related to an item rendered by the device 200 (such as a reaction to that item), and / or a command to be transmitted to a computer application used by the device 200, for example an application running at least partially on the device 200 or an "online" application running at least partially remotely, for example on the server 160 of the system 100.Examples of input user interfaces for the 200 device include one or more sensors for detecting movement (e.g., a user's eye movement) such as one or more motion sensors, one or more eye-tracking devices, one or more cameras, sensors for acquiring sound such as a microphone, a means of acquiring a command (e.g., one or more key(s), a . keyboard, a button, a pointing device (mouse), a touch screen actuator) etc.

[0088] The device may also include image analyzers capable of interpreting a user's body expression or identifying a user on a visual element (image, video) representing that user.

[0089] Said at least one microprocessor of the device 200 may in particular be adapted to implement at least one of the methods of the present application.

[0090] Thus, in certain embodiments, said at least one microprocessor of the device 200 may in particular be adapted to implement a method for assisting in the sharing of a multimedia element, said method comprising: - obtaining at least part of a multimedia element intended to be shared by a first user of said electronic device to at least two second users of second electronic devices, said second users being distinct from said first user; - a provision, for said first user, of at least one piece of information representative of a perception of one or more portion(s) of said multimedia element by at least one of said second users, said representative information being for example information that does not allow the said second users to be distinguished from each other (such as anonymized information).

[0091] In certain embodiments, said at least one microprocessor of the device 200 may in particular be adapted to implement a method for transmitting, to a first electronic device (different from or identical to the device 200), a perception relating to a multimedia element, said transmission comprising: - at least partial acquisition of at least one multimedia element; - A provision, in said first electronic device, of at least one indication of perception of one or more portion(s) of said multimedia element by a second user of said second device, said perception indication being obtained automatically by said second device.

[0092] To this end, the device 200 may include, for example, among other things, a multimedia element analysis module, a knowledge management module, and / or a transfer module, and a module for processing feedback relating to the second users receiving the shared element

[0093] The analysis module may, for example, be responsible for the analysis of the multimedia element performed by the device 200, described in particular in connection with Figures 3B and 4C. The knowledge management module may, for example, be responsible for searches in knowledge bases described below in particular in connection with Figures 3B and 4C.

[0094] The transfer module may, for example, be in charge of data transmissions from, or to, device 200 for the implementation of at least one of the methods of this application.

[0095] Optionally, the device may also include conversion modules, such as text-to-voice or voice-to-text converters.

[0096] It should be noted that in some embodiments, the device can be adapted to both the implementation of the assistance method and the retrieval method, whether at different times or simultaneously. In other embodiments, on the contrary, the methods of the present application can be implemented by different devices.

[0097] Some of the above input / output modules are optional and may therefore be absent from device 200 in certain embodiments. In particular, while the present application is sometimes detailed in relation to a first device communicating with at least one second device of system 100, at least one of the assistance and perception feedback processes may also be implemented locally by a device (at different times, for example), in which case some of the communication modules may be absent (or inactive).

[0098] On the contrary, in some of its embodiments, at least one of the assistance or recovery processes can be implemented in a distributed manner between at least two devices 110, 120, 130, 140, 150, 160, 170, 190 of the system 100.

[0099] For example, either of the processes can be executed partially on a terminal and a server, and use at least one knowledge base dedicated to a user of another terminal and accessible to that server (via a local network for example).

[0100] The term "module" or the term "component" or "element" of the device refers here to a hardware element, in particular a wired one, or a software element, or a combination of at least one hardware element and at least one software element. The methods according to the invention can therefore be implemented in various ways, in particular in wired and / or software form.

[0101] Some embodiments of the assistance method 300 of this application are now presented in more detail in connection with Figures 3A to 3C (some embodiments of the method of raising the data in this application are then detailed in connection with Figures 4A to 4C).

[0102] The method 300 can, for example, be implemented by the electronic device 200 illustrated in [Fig. 2]. This can include, in particular, a first device (such as a terminal) whose user wishes to share a multimedia element with other users of that electronic device or other electronic devices, or even of a server of system 100 communicating with such a first device to provide this first user with a support service.

[0103] As already explained, for simplicity in the request the user wishing to share a multimedia element is referred to as the "first" user and the "other" users as "second" users.

[0104] As illustrated in [Fig. 3A], the assistance method 300 may include obtaining, at least partially, a multimedia element 320 to be shared. In some embodiments, this may be a pre-existing element (e.g., multimedia content), accessible locally or remotely to the first device. This multimedia element may, for example, have been previously created by a user for whom the assistance method is implemented, or by a third-party user. For example, it may be an off-the-shelf multimedia element (such as a multimedia element belonging to a content library). In such embodiments, the assistance method may then allow for a post-hoc evaluation of the multimedia element with regard to at least some of the expected consumers of this multimedia element (before its distribution to these consumers or during its distribution).

[0105] In some embodiments, this may be a multimedia element under construction, partially obtained, on which the assistance process can be implemented progressively according to the "target" consumers of this multimedia element. For example, it may be an audiovisual stream being acquired, the dissemination of which is carried out as it is acquired. For example, it may be an audiovisual stream corresponding to the speech (audio or video) of a participant in a videoconference.

[0106] The multimedia element can in particular be generated on the device 200 (in particular when it is a terminal type electronic device) or received by the device 200 (for example when the device 200 is a server).

[0107] As illustrated in [Fig. 3A], the assistance method may include obtaining 360° information representing a perception by at least one of the secondary users (and target consumers) of at least a portion of the multimedia element. This information representing a perception is also referred to, for simplicity, hereinafter as summary information.

[0108] In the example of [Fig. 3A], the assistance method may further include a provision 370 of this summary information. By provision is meant a process comprising rendering on an output user interface of the device 200, and / or sending to another device, and / or storing on and / or from the device 200. Optionally, the provision 370 of the summary information may be accompanied by a designation of at least a portion of the multimedia element.

[0109] According to a first example, when device 200 is a server (like server 160 in [Fig. 1]), the provision may include sending to the first device of the first user wishing to share the multimedia element).

[0110] According to a second example, when device 200 is the device of the first user wishing to share the multimedia element, the provision of the synthesis information may include rendering the synthesis information (or an information element taking into account this synthesis information) on an output user interface of device 200.

[0111] When the provision of summary information includes rendering, this rendering can, for example, be synchronized with the multimedia element (so as, for example, to "render" at the same time a page of a slideshow and the summary information relating to the content of that page).

[0112] According to a third example, the provision may include storing summary information (for example, in a storage device such as device 150 in [Fig. 1]) for later use. The summary information may, in particular, be stored in association with the multimedia element (for example, in the form of metadata). Thus, when summary information is provided before the multimedia element is shared, in certain embodiments, the summary information may be stored in association with the multimedia element, to be rendered on the device of a "first" user sharing this multimedia element when sharing it (for example, synchronously with the part of the multimedia element currently being shared), so as, for example, to assist this "first" user when presenting the multimedia element during its sharing.

[0113] The summary information provided to the first user, through the assistance process of this application, can thus allow, for example, the broadcasting of the multimedia element to be adapted accordingly (for example, by broadcasting a second element complementary to this multimedia element (such as an oral or textual commentary, for example), in conjunction with the broadcasting of the multimedia element).

[0114] The summary information provided to the first user may also allow, in certain embodiments where the multimedia element is modifiable, for the multimedia element to be modified accordingly, prior to its distribution, for better adaptation to the "target" consumers of this multimedia element.

[0115] As previously stated, providing summary information includes, in particular, rendering the summary information on an output user interface of the first device, and / or storing the summary information for subsequent use of this information, for example in association with the multimedia element (in the form of metadata for example).

[0116] Thus, when summary information is provided before broadcasting the multimedia element, the summary information can in certain embodiments be stored in association with the multimedia element, to be rendered on the first device when the multimedia element is broadcast, (for example synchronously with respect to the portion of the multimedia element) so as, for example, to assist a presenter of this multimedia element using the first device.

[0117] It is noted that the assistance process can be implemented according to the embodiments systematically or on subscription 310 to a service (and possibly manual activation (not illustrated) of this service by the first user wishing to share a multimedia element, this subscription 310 and / or this possible activation being able to be implemented before or during this sharing.

[0118] For example, the assistance method can be implemented continuously, during the rendering of a multimedia element (periodically or according to variations in the rendering of the multimedia element (at each page change when the multimedia element is a slideshow, for example). According to another example, it can be implemented at the request of the first user (via the user interface of device 200, for example).

[0119] The obtaining of summary information in relation to [Fig. 3B] is now described in more detail in embodiments where the assistance method implements at least a partial analysis 330 of the multimedia element at least partially obtained 320 by the device 200, prior to or during the sharing of this multimedia element. (Note that this analysis may be optional in other embodiments as explained later).

[0120] For simplicity, the subscription to the (optional) support service is not illustrated in [Fig.3B].

[0121] As illustrated in [Fig. 3B], in certain embodiments, at least a partial analysis of the multimedia element can be implemented, so as to identify items of this multimedia element whose perception by secondary users, the "target" consumers of this multimedia element (pl secondary users in the example of [Fig. 3A], with pl a natural number greater than 1), is to be evaluated a priori. These items can, for example, be items extracted from the multimedia element (e.g., by natural language processing techniques). They can include, for example, named entities, keywords, specific static (e.g., logo) or dynamic (e.g., video) graphic elements, acronyms, abbreviations, mathematical formulas, etc.

[0122] Optionally, before or during evaluation 336, the process may include a selection 334 of items to be evaluated from among the identified items. For example, the selected items may include items considered, for example by parameterization or annotation of the multimedia element, as important to the author and / or owner of the multimedia element, or the first user.In a complementary (alternative or cumulative) manner, the selected items may include items considered a priori as likely to be poorly known by at least one of the consumers of the multimedia element. The selection may for example include a search in a knowledge base accessible to device 200, such as a general knowledge base to system 100 (a dictionary) and / or a search in a database listing audiovisual items poorly known to the user wishing to share the multimedia element (or conversely audiovisual items well known to this user).

[0123] The evaluation 336 of the identified (and optionally selected) items can, for example, be carried out by searching in at least one knowledge base accessible to the device 200, such as at least one knowledge base listing well-known (respectively poorly known) audiovisual items of at least one of the second target consumer users of the multimedia element (such as bases specifically associated each with one of the target consumers, or a base associated with several consumers having common characteristics, such as belonging to the same organization or similar socio-professional characteristics).Specifically, this could be a knowledge base accessible locally to device 200 (for example, when it is a server implementing the assistance process in a "centralized" manner), or database(s) accessible remotely, for example on a remote storage device, or via the devices used by these second users (by querying these devices, for example). In the example illustrated in [Fig. 3B], the evaluation covers ni items, with ni a natural number at least equal to 1.

[0124] The evaluation 336 of the identified items may optionally include a transmission 3362 to at least one third-party device of at least one item to be evaluated. This third-party device may, for example, be a server (such as server 160 in [Fig. 1]), a storage device (such as device 150 in [Fig. 1], or one of the devices of the "second" users to whom the multimedia element is to be shared (for example, at least terminals 110, 120, 130, 140, 190 in [Fig. 1])).

[0125] The evaluation 336 of the identified items can provide 3364, depending on the results of searches carried out locally or remotely, indications of the perception of these items for at least some of the secondary users, these indications of perception being, for example, each specific to one of these second users. Obtaining 3364 perception indications may optionally include receiving these perception indications from a third-party device to which at least one item to be evaluated has been transmitted.

[0126] Perception indicators may vary depending on the embodiment. In particular, in some embodiments, it may be a Boolean value (indicating, for example, knowledge or lack of knowledge of the item by the user concerned). In some embodiments, it may be a numeric indicator taking a value belonging to a discrete set of at least 3 distinct values. In some embodiments, it may be a numeric indicator belonging to a numeric range defined, for example, by lower and upper bounds (parameterizable, for example) representing, respectively, knowledge and lack of knowledge of the item by the user concerned (or vice versa), the proximity of the relevance indicator to these bounds being representative of the "perceived" knowledge of the second user.

[0127] It is noted that depending on the embodiments, perception indications can be obtained for all the second "target" users of the sharing, or only for some of them (for example, those who have accepted this feedback of perception information, for example by subscribing to a service for reporting perception indications, complementary to the assistance service and / or, optionally, by having also activated this service).

[0128] The method 300 may further include obtaining 360 at least one summary piece of information from at least some of the "individual" perception indications obtained 3364. For example, a summary piece of information may correspond to a synthesis of the perception by all secondary users (or by a subset of these secondary users) of one of the identified items, such as a number or a percentage of secondary users familiar with that item. An example of rendering may be a text label such as "Item X known by k% of the recipients of the share (or alternatively by p recipients out of the n recipients)."

[0129] Another example of rendering could be a text label such as "Item XL known by pl / n recipients" (where n represents the total number of recipients).

[0130] According to another example, a joint rendering of summary information relating to portions of the multimedia element shared synchronously can be carried out (for example, a joint rendering of summary information relating to items on the same page of a paginated multimedia element).

[0131] Obviously, depending on the embodiment and the portion and multimedia element considered, the number of summary information items provided and / or the number of summary information items provided simultaneously may vary.

[0132] It should be noted that the provision 370 of summary information relating to an item may optionally include a designation 372 of at least a portion of the multimedia element. In the example of [Fig. 3B], this may include, in particular, a portion of the multimedia element in which that item has been identified. This designation may vary depending on the embodiment. It may include, for example, a designation of a page number of the multimedia element concerned, if it is a paginated document, and / or a designation of the position of the item to which the summary information relates within the portion concerned,...).

[0133] Where the provision includes a rendering of summary information, the method may include a joint rendering of an indication relating to the designated portion, such as a label, graphic highlighting (like underlining, a specific color associated with the portion in a heat map rendered jointly with the multimedia element, etc.). The rendering of the information may, depending on the embodiment, be synchronized with the rendering of the portion of the multimedia element containing the item to which the summary information relates, or be performed continuously (even if the item to which the summary information relates is no longer being rendered). Such an embodiment may, for example, help a presenter to provide additional information relating to that item after the fact.

[0134] Other embodiments are now presented in connection with [Fig. 3C] where the method includes a transmission 340 of the multimedia element, either during or after its acquisition 320, without prior analysis of this multimedia element by the device 200. This could involve, for example, sharing a multimedia element during a videoconference, with synchronous consumption of this multimedia element by the second users. It could also involve sharing multimedia content (via email, for example) for subsequent consumption of this content by one or more of the second users. In such embodiments, the analysis can be performed by a third-party device (such as the server 160 and / or the devices of the second users).

[0135] For simplicity, the subscription to the (optional) support service is not illustrated in [Fig.3C].

[0136] As illustrated in [Fig. 3C], the method may include a transmission 340 of the at least partially obtained multimedia element to at least one third-party device (such as the server 160 and / or the devices of the second users). Thus, [Fig. 3C] shows a transmission to p third-party devices (p an integer at least equal to 1). As illustrated, the method 300 includes a reception 350, from at least one of these third-party devices, of at least one perception indication (reception 352) from at least some of the second users, with respect to at least a portion of the transmitted multimedia element (for example, with respect to at least one item contained in this portion). Thus, [Fig. 3C] shows a reception of p2 perceptual indications (p2 being an integer at least equal to 1). These perceptual indications may be similar to the perceptual indications already described in connection with [Fig. 3B].

[0137] As illustrated in [Fig. 3C], the method may optionally include receiving a designation (reception 354) of at least a portion of the multimedia element, in association with at least one received perception cue 352, this perception cue being then relative to that portion. For example, it may involve receiving a designation of a portion of the multimedia element comprising an item (as described above) to which the received perception cue relates. Depending on the embodiment, the designation information and the perception cue may be received 350, 352, 354 jointly or sequentially.

[0138] The process 300 may further include obtaining 360 at least one summary piece of information from the received portion designations 352 and the received “individual” perception indications 354. According to a first example, a summary piece of information may correspond to a synthesis of the perception indicators received for the same portion of the multimedia element (such as, for example, an audiovisual item as introduced above). According to a second example, a summary piece of information may correspond to a synthesis of the perception indicators received associated with portions having at least one common part.

[0139] The method 300 may further include a provision 370 of the resulting summary information 360. As explained above, this provision may optionally be accompanied by a designation 372 of at least one portion of the multimedia element. In the embodiment illustrated in [Fig. 3C], this may be at least one portion associated with at least one perception cue from which the summary information was obtained. For example, the designated portion may be a portion associated with all the perception cues from which the summary information was obtained, i.e., an "intersection" of the portions associated with each of the perception cues from which the summary information was obtained.According to another example, the designated portion may be a portion bringing together all the portions associated with perceptual cues from which the synthesis information was obtained, i.e. a "union" (or aggregation) of the portions associated with each of the perceptual cues from which the synthesis information was obtained.

[0140] Some embodiments of the lifting process 400 of this application are now presented in more detail with reference to Figures 4A to 4C. The lifting process, in the detailed embodiments shown in relation to [Fig. 4A] (respectively 4B, respectively 4C), can in particular be used to process data from the assistance process of [Fig.3A] (respectively 4B, respectively 4C).

[0141] For example, the retrieval process can be implemented each time data (multimedia element, item, etc.) is received from the assistance process. It can also be implemented systematically when a shared multimedia element is obtained (periodically or as the multimedia element is rendered), or upon receipt of a specific request from the device sharing this multimedia element or from the second user (via the user interface of device 200, for example).

[0142] The method 400 can, for example, be implemented by the electronic device 200 illustrated in [Fig. 2]. This may include a device (referred to in this application as a "second" device) of which a user (referred to in this application as a "second" user) is one of the persons with whom a user of a first device wishes to share, or actually shares, at least part of a multimedia element. The method is implemented to allow the retrieval of at least one relevance indicator for this second user, relating to one or more portions of this multimedia element. Depending on the embodiment, this may be an "a priori" relevance for this second user or an actual relevance. The second device may be, for example, a server or a communication terminal.

[0143] As illustrated in [Fig. 4A], the retrieval method 400 may include obtaining 450 at least one relevance indicator for this second user, relating to one or more portions of this multimedia element. This may be, for example, at least one relevance indicator as described above in connection with one of Figures 3A, 3B and / or 3C and / or below in connection with [Fig. 4B] or 4C.

[0144] The feedback method 400 may further include a transmission 460 of at least some of the relevance indication(s) obtained to a device emitting the multimedia element (for example, the device of the first user or an application server). This transmission may be conditional (for example, in some embodiments, only certain perception indications obtained may be transmitted (for example, only perception indications obtained that are representative of a low level of knowledge or understanding of the second user may be transmitted)).

[0145] It is noted that the 400 method of retrieval can be implemented according to the embodiments systematically or on subscription 410 to a service (and possibly manual activation of this service by the second user).

[0146] The obtaining of perceptual indications in relation to [Fig. 4B] is now presented in more detail in embodiments (for example, “at least partially centralised") where the 400 retrieval process includes obtaining 430 (receiving, for example) at least one audiovisual item from the multimedia element (as already described in connection with [Fig.3B]) whose perception for this second user is to be evaluated.

[0147] For simplicity, the subscription to the (optional) perception indication(s) reporting service is not illustrated in [Fig.4B].

[0148] The method 400 of retrieval can thus include obtaining 450 at least one indication of the perception, by the second user, of the item obtained.

[0149] The perception indication obtained for an item may be based on an assessment of the item's relevance to the second user. For example, it may take into account the results of searches performed on that item in knowledge bases. For instance, the process may include a search in at least one knowledge base accessible to the device 200, such as at least one knowledge base listing audiovisual items known (or poorly known) to the second user (the target consumer of the multimedia element). These may be, for example, databases specifically associated with the second user or shared between the second user and other consumers of multimedia elements, these other consumers having characteristics in common with the second user (as described in relation to [Fig. 3A]). In particular, it may be a knowledge base accessible locally or remotely to the device 200.

[0150] The perception indication may also correspond to a level of attention paid by the second user to the rendering of this item on the device 200 (for example, attention paid to an area of ​​the screen where this item appears). This level of attention may, for example, be measured by an eye-tracking module installed on the device 200 (based on the time spent observing this item, for example).

[0151] The perception indication may also correspond to an interpretation of a body expression (facial for example) or a movement of a second user during the rendering of the item by the device 200. Such a body expression or such a gesture may, for example, be captured by a camera coupled to an eye-tracking module of the device 200. For example; the acquisition of a "frown" may be interpreted as a poor knowledge by the second user of the item in question.

[0152] As illustrated, the method may also include a transmission 460 of the perception indication to the emitting device of the multimedia element (as described in connection with [Fig.4A]).

[0153] Other embodiments are now presented in connection with [Fig. 4C] where the retrieval process includes at least partial acquisition (e.g., reception) of the multimedia element. This may be, for example, an element multimedia currently being shared or intended for later sharing with the second user.

[0154] For simplicity, the subscription to the (optional) perception indication(s) reporting service is not illustrated in [Fig.4C].

[0155] The method 400 of retrieval may further include obtaining 450 at least one indication of the perception, by the second user, of at least a portion of the received multimedia element and obtaining a designation of this portion.

[0156] In certain embodiments, similarly to what has been described in connection with [Fig. 3B], the method may include an analysis 430 of the multimedia element, so as to identify 432 of the items of this multimedia element whose perception (a priori or actual) by the second user is to be evaluated. Optionally, the method may include a filtering 434 of the items to be evaluated from among the identified items. For example, the filtering may allow only items considered, by parameterization or annotation of the multimedia element for example, as important to the author and / or owner of the multimedia element, or the first user, to be retained for evaluation.

[0157] The process 400 may include obtaining 450 a perception indication of the identified (and optionally selected) items. Obtaining 450 a perception indication for an item may be similar to that described in connection with [Fig. 4B].

[0158] Thus, similarly to what is described above for [Fig.4B], an indication of perception relating to an identified and / or selected item may be a function of search result(s) carried out on that item in knowledge bases, or correspond to a level of attention paid by the second user to the rendering of that item on the device 200 or to a body expression or gesture of the user when rendering that portion.

[0159] Optionally, the process may include obtaining a designation of at least one portion of the multimedia element to which at least one obtained perception indication relates. For example, it may be a designation of a portion of the multimedia element comprising at least one item (from the analysis described above) to which at least one obtained perception indication relates. 430

[0160] In certain embodiments, a perception indicator can be obtained (for example, as a complement to the analysis described above) by a manual action of the second user. For example, a manual action of the second user by means of a pointing device of the device 200 can allow the designation of a portion to which the second user can manually associate a perception indicator (representative, for example, of a good or poor knowledge of at least one term of this portion by the second user, or (of a correct or incorrect understanding of this portion by the second user) or to which a perception indicator can be automatically associated (via parameter settings, for example). Thus, in certain embodiments, the selection, by a mouse for example, of an item in a multimedia element rendered on the device 200 can be automatically associated with a misunderstanding or misinterpretation of that item by the second user. Such an embodiment can allow a user consuming the multimedia element to easily signal (during synchronous sharing, in particular) their misunderstanding of an item to the presenter of that multimedia element.

[0161] As illustrated, the method may include a transmission 460 of the perception indication to the first device and, optionally, a transmission 462 of the designation obtained from a portion.

[0162] A use case is now presented in connection with [Fig.5].

[0163] Figure 5 illustrates, in chronological form, certain exchanges and processing carried out between participants in a teleconference, a first participant PI wishing to share a multimedia element (a slideshow in this example) with second participants P2, P3. The exchanges take place between a first device 502 of the first participant PI and second devices 504, 506 of these second participants, via (optionally) a dedicated server 508.

[0164] As illustrated in [Fig.5], before the sharing 520 of the multimedia element, the first device subscribes t 512 to a sharing assistance service with a dedicated server 508 and the second devices 504, 506 subscribe respectively 514, 516 to a complementary service of collection indication feedback with the dedicated server 508.

[0165] During the sharing of the slideshow 520, the first PI participant activates the support service.

[0166] The first device 502 transmits the relevant page to the server 508, which analyzes the received page and identifies items to be evaluated. It then transmits these items to devices 504 and 506. These devices consult local databases representing the knowledge of users P2 and P3, respectively, obtain indications of the relevance (here, knowledge levels) of these items, and transmit them back to the server 508. The server deduces summary information regarding the knowledge levels of the items present on the received page. The server transmits this summary information to the first device. This summary information is returned by the first device 502 along with the relevant slideshow page, so as to allow participant PI to adapt the oral presentation of the slideshow accordingly.

[0167] It should be noted that in the example illustrated in [Fig. 5], the summary information is obtained at the request of the PI participant. Alternatively, the summary information can be obtained automatically, without user action, the multimedia element being analyzed continuously by the server.

[0168] The present application may find applications in various fields, both professional and personal, for the sharing of multimedia elements to multiple recipients.

[0169] For example, it can be used to assess the perception of a multimedia element by a panel of users before wider distribution of that multimedia element. In particular, it can help to adapt a multimedia element to its intended audience or to adapt its presentation to that intended audience, without requiring prior knowledge of that audience by the author of the multimedia element or by a presenter of that multimedia element.
