[0001] The invention relates to a method for managing a display interface formed from a plurality of screens of connected watches worn by users located in the same place.

[0002] The invention also relates to a computer program implementing such a method. Technological background

[0003] During visual and / or audio events such as concerts or sporting events, it is common for members of the public to hold electronic devices such as smartphones, video cameras or cameras, particularly to capture moments of these events.

[0004] However, such use of these devices during these shows has the major disadvantage of systematically generating visual pollution which then disrupts their smooth running.

[0005] Under these conditions, it is understood that there is a real need to find a solution to overcome these drawbacks of the prior art. US 2018 / 024800 A1 discloses a method for managing a display interface formed from a plurality of display screens. Summary of the invention

[0006] One of the aims of the present invention is therefore to propose a method which aims to take advantage of the screens of connected watches to contribute to the visual show of such visual and / or sound animations, according to claim 1. The preferred embodiments are defined in claims 2 to 9.

[0007] The invention also relates to a computer program, according to claim 10, comprising program code instructions for the execution of such steps of the method when said program is executed by the processing units of a connected watch and of a display interface management server. Brief description of the figures

[0008] The invention will be described below in more detail with the aid of an attached drawing, given by way of non-limiting example, in which: There figure 1 is a representation relating to a method for managing a display interface formed from a plurality of screens of connected watches worn by users located in the same place, according to an embodiment of the present invention. Detailed description of the invention

[0009] On the figure 1, a method is illustrated for managing a display interface formed from a plurality of display screens 3 of connected watches 1 worn by users located in the same place. In this context, the watches are therefore located close to each other to form this display interface. Such connected watches are worn on parts of the users' bodies. These parts are likely to be in motion or are in motion and may include, for example, the wrist, ankle, arm, foot, neck, leg or arm of each of the users. Such a display interface is therefore formed by all the screens 3 of the connected watches 1 of users which are all located in the same place / location / location. It is therefore understood that the users, each wearing a connected watch 1, may be grouped together in a concert hall or in an arena or even a stadium where, for example, a sporting performance is to take place.

[0010] In this method, the visual message is displayed by all the screens 3 forming the display interface. Each screen 3 represents a secondary screen 3 of the connected watch. This secondary screen 3 is not defined to display information intended specifically or exclusively for the user of said watch. Such information relates to the functions performed by the watch 1 such as time information, alarm information, geolocation information, meteorological information, health information (blood pressure, heart rate, pulse oximetry, electrocardiogram), activity information, sports training information or “sports coaching”, etc., as can be the case here with a main screen 4 of the watch 1.Indeed, such a screen 3 is arranged in the watch 1, for example in the bracelet 5 of the latter, being configured to be controlled / administered by a management server 2 of the display interface included on a remote technical platform. This screen 3 is of the active matrix type and comprises electroluminescent electrodes. It is also deformable and stretchable. Under these conditions, it is understood that each of these screens 3 is preferably specifically dedicated and configured to produce such a display. In other words, the screens referenced 3 of these connected watches each have the sole function of displaying a portion of the visual message transmitted by the management server. In addition, these screens 3 each have the sole function and / or destination of constituting said display interface.

[0011] This visual message is different from functions performed by the watch 1 in particular because their broadcasting does not result from a prior configuration of a computer application of the watch by the user or from an interaction between the input interface of this watch 1 and the user. In addition, these visual messages are not intended exclusively for the wearer of the watch 1 as may be a function of the watch 1 such as an alarm. In the context of this embodiment, each visual message relates to a visual and / or sound animation (for example a sporting or cultural event, a show, a concert, etc.) included / organized in an environment / location / place where said watch 1 is located. As we have already mentioned, this visual message is intended for a display interface formed by several screens of connected watches 1 arranged in an environment / location / place close to the connected watch 1.In addition, this visual message aims, for example, to provide a visual contribution to the visual and / or sound animations. It is therefore understood that the content of this visual message is directly related to the visual and / or sound animation included in the environment where the connected watch 1 and therefore the user of the watch 1 is located. Such content may be synchronized or coordinated with this visual and / or sound animation. By way of example, such a visual message includes an animated or static graphic representation. In a non-limiting and non-exhaustive manner, this message includes an image comprising objects or a light pattern or a symbolic representation of an emotion of the “emoticon” type, an image exchange format (better known by the acronym GIF for “Graphics Interchange Format”), a word / term or a group of words / terms or a video.

[0012] This method comprises a step 10 of estimation by at least one processing unit 6 of each connected watch 1, of at least one broadcast characteristic of each display screen 3 in said display interface that they form together.

[0013] This step 10 includes a sub-step 11 of establishing measurement data relating to at least one of the broadcasting characteristics, carried out by each connected watch 1. The broadcasting characteristic includes, in a non-limiting and non-exhaustive manner: a characteristic of locating the watch 1 relative to the other connected watches 1 whose secondary screens 3 form the display interface and / or a characteristic of orienting the screen 3 of said connected watch 1 by the orientation of the secondary screens of these watches.

[0014] Such characteristics aim to identify / evaluate the broadcasting properties of each screen 3 in order to optimally configure the broadcasting parameters of the display interface consisting of these screens 3. In other words, it is understood for example that a screen 3 can be activated / deactivated, that is to say that it is capable of broadcasting or not broadcasting a portion of the visual message depending on its position and / or its orientation.

[0015] Such a sub-step 11 then provides an evaluation phase 12 implemented by the processing unit 6 connected to a positioning capture module 7 of each watch 1. During this phase 12, measurement operations are carried out in order to evaluate the position of each watch 1 relative to other connected watches 1 which are located in its immediate environment. This positioning capture module 7 of the connected watch 1 is able to detect the other connected watches 1 which are arranged in its immediate environment, that is to say the other watches 1 which are close to it or in the vicinity of it. In addition, this module 7 of the connected watch 1 is able to determine the distance which separates it from the other watches 1 and to position each of the other watches 1 which are close to it relative to / in relation to its own position. To do this, such a module 1 can implement: a low-energy Bluetooth ™ type technology also called in English “Bluetooth low energy” and better known by the acronym “BLE” and in particular a functionality of this technology called radio direction finding, and / or an Ultra Wide Band type technology known by the acronym in French “ULB” and in English UWB “ultra wideband”.

[0016] The establishment sub-step 11 also comprises a phase 13 of estimating the orientation of the screen 3 of each watch 1. Such a phase 13 makes it possible in particular to identify the direction of diffusion of this screen 3 of each watch 1. Such a phase 13 is implemented by the processing unit 6 and a module 8 for measuring the orientation of the screen 3 connected to this unit 6. This measurement module 8 may comprise one or more inertial sensors of the accelerometer, gyroscope or miniature multi-axis gyrometer type such as multi-axis sensors manufactured in MEMS technology, capable of detecting angular speeds and linear accelerations along several axes associating accelerometers and / or gyroscopes.

[0017] Subsequently, the method comprises a step 14 of transmission by the connected watches 1 of said measurement data to a management server 2 of the display interface. During this step 14, the processing unit 6, being connected to a communication interface of each connected watch 1, sends this data to this management server 2 via a communication network, such measurement data comprising the location and orientation characteristics. This data received by the server 2 is then archived in memory elements 9 of this server 2.

[0018] The method then comprises a step of managing the display 15 of a visual message on said display interface comprising a sub-step of generating 18 portions of said visual message as a function of the measurement data relating to at least one broadcast characteristic, each portion being intended to be displayed on the screen 3 of each connected watch 1. To do this, such a step 15 comprises a sub-step of producing 16 a visual message to be displayed on said display interface.

[0019] Such a substep 16 comprises a phase of generating visual message data. This visual message data participates in the creation of this message. Such visual message data comprises contextual data relating to information concerning: a theme / subject of the visual and / or sound animation / event of the place where the visual message is likely to be broadcast, and / or criteria for synchronization or coordination between this animation / event and the visual message to be broadcast.

[0020] In other words, such a visual message is preferably produced in relation to the theme of the animation / event where it will be broadcast by being, for example, synchronized or coordinated with this visual and / or sound animation. The visual message data also includes visual message definition data which are designed by a processing unit 20 of the management server 2, for example from an input interface 21 of the server 2, connected to the processing unit 20 where it is then possible to enter a message or to select a predefined message archived in the memory elements 9 of the server 2. Subsequently, the display management step 15 includes a sub-step 17 of designing a map relating to the arrangement of all the connected watches 1, in particular the secondary screens 3, the constituents and forming the display interface.This sub-step 17, which is implemented by the processing unit 20 of the server 2, comprises a phase of selecting the secondary screens 3, which are the most suitable for broadcasting the visual message produced, with regard to their orientation, the distance which separates them from other screens 3 and their arrangement relative to these other screens 3. Such a selection phase comprises a sub-phase of processing the measurement data and virtual message data. It will be noted that the virtual message data participate in defining in particular the nature or type of visual message produced to be broadcast. In other words, such a selection phase is carried out from the measurement data and also according to the nature or type of visual message produced to be broadcast. On this basis, the processing unit 20 then constructs a virtual representation of the display interface on which the visual message will be displayed.In addition, we understand that depending on whether the visual message conveys information that must be read (for example an image containing objects or text) and perceived by an individual, the distance between the screens 3 and their orientation are parameters that are assessed in a more restrictive manner to allow this reading than for a visual message that aims to create light effects.

[0021] Under these conditions, following the completion of this sub-step 17, the generation sub-step 18 then provides during its execution that the processing unit 20 of the server 2, identifies from the mapping relating to the arrangement of the screens 3 constituting the display interface, the screens 3 which are capable of broadcasting said visual message. Subsequently, this processing unit 20 carries out operations of separation / division of the visual message into as many portions as there are screens 3 to ensure the broadcasting of the visual message on the visual interface. These portions are then transmitted to the corresponding connected watches 1 via the communication interfaces of the server 2 and the connected watches 1.

[0022] Note that the portions may have similar content, for example in the case where the visual message relates to phased and coordinated lighting effects.

[0023] The method then comprises a step 19 of broadcasting the portions of said visual message on each screen 3 of connected watch 1 constituting this display interface in particular according to their arrangement in this interface.

[0024] It is understood that steps 10 to 19 of this process are repeated as many times as necessary to ensure optimal diffusion of the visual message, in particular to take into account the numerous movements that can be made by the users of its connected watches 1 often worn on a part of the body in motion or likely to be in motion of these users such as the wrists.

[0025] The invention also relates to a computer program comprising program code instructions for executing steps 10 to 19 of the method when said program is executed by the processing units of a connected watch 1 and of a management server 2 of the display interface.
