Description

Title of the invention: Intelligent device communicating by light emission

[0001] The invention relates to communication between a device and a user. It relates in particular to the solicitation of a user by a device in the form of a light emission.

[0002] The proliferation of connected devices, such as smartphones, and applications developed for these devices, makes their users constantly informed, makes them the subject of requests, and makes them available for any type of interaction. This is materialized through various requests emitted by the devices and formed by messages, visual or audio notifications, calls. These requests are the source of interruptions, information overload and sensory saturation having a significant impact on concentration and productivity, as well as on physical, mental and cognitive health. In particular, concerning health, impacts on sedentary lifestyle, eyesight, sleep, diet, anxiety, depression, memory, attention disorders and the general decline in intelligence are identified, among other things.

[0003] The state of the art of applications, for connected devices, dedicated to moderating digital uses, and devices with deliberately limited functionalities, for example the return to so-called "9-key" telephones, to reduce the frequency and / or number of requests, is already known. However, these solutions prevent the user from receiving certain requests that he would have deemed relevant at the time they were intended for him. Furthermore, they often only result in delaying in time the flow of requests that the user will eventually experience.

[0004] The invention aims in particular to reduce the informational noise generated by the requests received by the user of a device.

[0005] To this end, the invention relates to a method of communication by light emission with a user, comprising the following steps:

[0006] - by wireless communication, sending, from a first device to a second device, of a solicitation intended for the user,

[0007] - preparation of a content of a light emission formed as a function of the solli quote,

[0008] - generation of the light emission, by the second device, for the purpose of the user,

[0009] - reception, by the second device, of a command from the user in response to light emission.

[0010] Thus, instead of soliciting the user with messages, notifications, alerts, calls, the first device sends this solicitation to a second device which generates a light emission formed according to the solicitation.

[0011] By "solicitation intended for a user", we mean in particular a signal relating to a message, a notification, an alert, a call, aimed at the user of the two devices, which the user would ordinarily only receive graphically and / or audibly by the first device. For example, the solicitation may relate to an "SMS" received by the first device. The solicitation may have been created directly by the first device, for example when it is an event notification recorded in a calendar, or may have been transmitted in advance by a third-party device to the first device. We also mean a signal relating to a message, a notification, a call, aimed at the user of the second device but not necessarily that of the first device. The first device may for example be a device worn by a third party and sending a solicitation to the second device in order to solicit the user.

[0012] The transmitted request may be a radio signal, for example a signal sent according to the Bluetooth protocol, an infrared signal, a LiFi signal or other types of signals. In the case where the first device also has a light emitter, the transmitted request may be a light emission emitted from the first device to the second device, which in turn generates a light emission for the user.

[0013] By "light emission content" is meant the form of the light emission, in particular the hue(s) emitted, their brightness and their saturation, and, if this emission evolves over time, the pattern of the evolution, i.e. the manner in which the hue, brightness and / or saturation evolve, generally in a few seconds and possibly repetitively, to convey a meaning. In the case of several emitters present on the second device, the content of the light emission also means the manner in which the emitters are coordinated to emit several emissions based on the same request. The light emission necessarily relates to a color, the term "color" including white and black.

[0014] By "preparation of a light emission content" is meant the step of determining the hue(s) to be emitted, their brightness and saturation, and their possible evolution over time, as a function of the request. This preparation can be carried out by the second device as a function of the request received. It can alternatively be carried out by the first device directly on the basis of a request that it has created or that it receives. It can also be carried out by a third-party server, in particular a CLOUD platform, before transmission to the second device.

[0015] By "light emission formed as a function of the solicitation" is meant the fact that the content of the light emission depends directly on the type and content of the solicitation. It is by transforming a solicitation into light emission that the informational noise is reduced.

[0016] The light emission aims to compress the request to make it easier for the user to process. Indeed, the light emission involves the emission of a color clearly visible to the user. The color provides information to the user that he quickly understands without him having to make any effort. It is thus known to use color in alert systems, for example in the dashboards of motor vehicles, marine vehicles or in airplanes, where the hues are directly associated, in the human brain, with levels of safety or danger.

[0017] Color is thus a communication choice based on human physiology, as explained in the following paragraphs.

[0018] It has been described that color supports several stages of the C-HIP (for "Com-munication-Human Information Processing") model, a model concerning the processing of human information in communication, in particular when it is applied to warnings (Wogalter, 2006). Color supports in particular the initial change of attention of its recipient, comprehension, memorization.

[0019] Studies (Young, 1991, Laughery et al, 1933) have shown that color results in faster response times than other forms of communication.

[0020] Color also plays a role in human selective attention. This selective attention is the allocation of attentional resources that the human visual system grants to the environment, faced with the immensity and complexity of the visual information received (Chun, Golomb, Turk-Browne, 2011). It can be considered that few attentional resources are necessary for the processing of light emissions compared to other resources necessary for other forms of visual information.

[0021] Color-in-Context theory (CIC) deals with the communication of meanings and associations containing important information through color. These meanings and associations are rooted in human predispositions based on learning and / or biology. This theory teaches, among other things, that color triggers automatic behavioral processes.

[0022] The generation of a light emission by the second device therefore makes it possible to inform the user of requests intended for his attention by reducing the resources necessary for his attention and therefore disturbing him less than a conventional request.

[0023] Furthermore, the step of receiving a command makes it possible to obtain feedback from the user on this light emission. This involves, for example, quickly responding to a question formulated via the light emission, or validating a proposal presented via the light emission. It also involves requesting to ignore a request, or requesting to present it later, or even to archive it. The process initiated by the light emission is less disruptive than the process initiated by a conventional request, so that the feedback is carried out more efficiently. This reception step also designates the possibility for the user to formulate feedback on the light emission itself, for example its understanding, its relevance in a given context.

[0024] Consequently, the informational noise generated by conventional requests is reduced.

[0025] Other optional features, taken alone or in combination, follow.

[0026] Advantageously, the request relates to one of the following types of elements:

[0027] - a call received by the first device for the user;

[0028] - a message received by the first device for the user;

[0029] - a notification from the first device to the user and bearing by example on an event, a location, a moment or an activity.

[0030] Thus, while these elements are traditionally transmitted to the user by an audible alert, a vibration or the display of an alert on a screen, here the first device does not transmit the solicitation in this manner to the user. Instead, it transmits the solicitation to a second device, by wireless communication.

[0031] Preferably, the content of the light emission comprising a pattern of the light emission, the pattern being composed of one or more luminosities and / or saturations of the light emission evolving over time, this pattern of the light emission corresponds to a degree of priority of the request intended for the user.

[0032] Thus, the variation in brightness and / or saturation of the light emission indicates a priority level of the request. This allows the user to easily understand whether he or she should quickly study the request or not. Categorizing requests by priority level allows for less disruption to the user, who may ignore a request if its priority level is low. Transmitting this degree of priority through a light emission is based on the effects on human physiology of this type of request: the user quickly and effortlessly understands the meaning of the pattern, which reduces the level of disruption to the user despite the request.

[0033] Advantageously, the content of the light emission comprising at least one shade of the light emission, this shade corresponds to a category of subjects concerned by the request intended for the user.

[0034] Thus, the user effortlessly and quickly understands what the solicitation refers to, without having to study it, i.e., read a message or listen to a recording. Here again, the level of disturbance to the user is reduced.

[0035] Preferably, the method comprises, before the step of generating the light emission, a filtering step, the step of generating the light emission only being implemented when it is determined in the filtering step that the request is relevant for the user.

[0036] Thus, the user is only solicited when the solicitation successfully passes the filtering step. Certain solicitations are therefore not transmitted to him, which reduces the disturbances to the user.

[0037] Advantageously, filtering criteria are determined by an artificial intelligence model trained from commands given by the user in response to corresponding past light emissions and corresponding past requests.

[0038] Thus, the artificial intelligence model is regularly updated, in particular on the servers of a CLOUD platform, or on the first or second device, or through a combination of these devices. This update, that is to say the training of the model on a learning base completed as it goes along, is carried out on the basis of past interactions between the user and the light emissions of his device. In this way, the next requests are transmitted to him only if, in view of his previous feedback, it is considered that they are relevant for him.

[0039] Preferably, the filtering criteria relate to at least one of the following elements:

[0040] - a type of element on which the stress is applied, for example among the types of the elements listed above;

[0041] - the solicitation being a message or notification received by the first device to user intent, message or notification content;

[0042] - a moment of reception of the request by the second device;

[0043] - a location where the second device is located;

[0044] - a current user activity identified by the second device.

[0045] Thus, these filtering criteria relate to a context during which the request is sent to the second device. The artificial intelligence model therefore learns to filter the requests based on the user's feedback on previous light emissions and in specific contexts. As a result, depending on a specific context, a light emission relating to the request may or may not be sent to the user.

[0046] Advantageously, the content of the light emission comprising a pattern and at at least one hue of the light emission, the pattern being composed of one or more luminosities and / or saturations of the light emission evolving over time, the pattern and the hue(s) are determined by an artificial intelligence model trained from past commands from the user in response to past corresponding emissions and past corresponding requests.

[0047] Thus, the artificial intelligence model learns to generate a content of the light emission based on the user's feedback on previous light emissions. For example, the user may indicate that they did not understand a light emission, or that they felt that its content, i.e. its hue and / or its pattern, was not relevant to the request to which it relates. The model therefore improves the accuracy of the light emission based on the request to which it relates.

[0048] Preferably, the user's command indicates a level of relevance of the light emission generated for his benefit, preferably a level of relevance among the following:

[0049] - irrelevant broadcast;

[0050] - relevant broadcast;

[0051] - irrelevant broadcast due to the context in which it was generated, the context being for example defined by data on the time and / or location and / or current activity of the user.

[0052] Thus, it is based on this user command in response to a light emission that it is possible to improve the relevance of future light emissions. In particular, the artificial intelligence model is updated based on these responses, and therefore improves the filtering criteria for requests and / or the content of future emissions relating to these requests, based on this feedback.

[0053] Advantageously, the user command is a voice command from the user received by the second device or a movement of the second device made by the user.

[0054] Thus, the second device has a microphone.

[0055] Advantageously, at least one of the devices among the first and second devices is a smart device.

[0056] By "intelligent device" we mean any device capable of receiving data, processing it, and deciding, based on this processing, whether or not to perform an action. These are devices equipped with means of communication, generally wireless, and processors, to carry out these tasks. They can also be called "connected devices".

[0057] Advantageously, at least one of the devices among the first and second devices comprises an “intelligent assistant”.

[0058] By "intelligent assistant", or "intelligent personal assistant", or "virtual personal assistant", we mean a software agent performing tasks for a user. In this case, this software agent generates the light emission formed as a function of the request. It may also be responsible for all or part of the other tasks described, in particular the preparation of the content of the light emission and the processing of the user's command received in response to the light emission. This agent may be configured to perform other tasks.

[0059] Preferably, the second device is a user-wearable accessory.

[0060] By “accessory” we mean a device whose dimensions and weight make it easily mobile and manipulated by a user.

[0061] The term "wearable accessory" refers to an accessory that a user can wear without having to perform a particular action, for example without actively holding it in their hands to keep it in position. In particular, we are talking about an accessory that the user can equip themselves with. In particular, it is an accessory that has means of attachment to the user, for example a brooch or a bracelet, or whose shape allows it to be worn without action, for example a ring worn around a finger. We can also talk about a "put-on" or "wearable" accessory. This device covers in particular the field of "habitronics" and is often referred to by the expression "wearable device" in English. We can consider that the adjective "wearable" is equivalent to those of "portable" or "handheld" only within the limit of an accessory that can be worn without active effort from the user.

[0062] Advantageously, the first device is a smartphone.

[0063] Thus, this is in particular the user's smartphone. Rather than transmitting the request directly to the user, via graphic or sound information for example, the smartphone transmits the request to the second device so that the latter generates a light emission relating to this request.

[0064] Alternatively, the first device is an accessory wearable by the user or by another user.

[0065] In this embodiment, the first device is therefore worn by the user or another user and transmits the request and transmits the request to the second device. Devices, for example wearable accessories, can thus operate in a network. The request can be transmitted from one device to another in the form of a radio signal, for example Bluetooth, infrared, LiFi, or even a light emission as described previously. In the latter case, the devices can communicate with each other by a language formed of light emissions.

[0066] The invention also provides a method for generating a light emission, implemented in a light emission communication device, the method comprising the following steps:

[0067] - reception, by wireless communication means of the device, of a solli quote intended for a user,

[0068] - a light emission formed as a function of the stress having been prepared, generation of light emission, by a light emitter of the device, for the user,

[0069] - reception, by means of receiving a command from the device, of a user command in response to light emission.

[0070] The invention also provides a computer program comprising instructions which, when the program is executed by a computer, cause the latter to implement the steps of one or other of the methods described above.

[0071] Also provided according to the invention is a computer-readable recording medium comprising instructions which, when executed by a computer, cause the latter to implement the steps of one or other of the methods described above.

[0072] The invention also provides an application platform, making available to a device, by downloading, the program introduced above implementing the method introduced above for generating a light emission by the device, or the program introduced even higher implementing, by the first device, the method introduced above for communicating by light emission with a user.

[0073] The invention also provides a light emission communication device, comprising:

[0074] - wireless communication means, for example a wifi antenna;

[0075] - a light emitter for generating a light emission, for example at less than one light-emitting diode;

[0076] - means for receiving a command from a user, for example an acce- lerometer, a gyroscope or a microphone;

[0077] the device being configured to implement the steps of the second device of the method described above.

[0078] Advantageously, the device further comprises at least one of the following elements:

[0079] - means for transmitting / receiving infrared waves;

[0080] - means for transmitting / receiving LiFi waves;

[0081] - a piezoelectric energy harvester.

[0082] The means for emitting infrared and / or LiFi waves make it possible to communicate with other devices, in particular in spaces without access to the Internet network. The device can therefore in particular receive a request from another device in the form of infrared or LiFi waves. LiFi allows data rates of high data rates, wide bandwidth, and increased security because light generally does not pass through solid obstacles. Within infrared waves, SWIR waves, for "Short-wavelength infrared," are advantageous in that they exploit a wide bandwidth and are less prone to interference than other types of waves. SWIR transmissions are also more secure and suitable for communication in low-light conditions.

[0083] The piezoelectric harvester makes it possible to recover energy coming from the user wearing the device and in particular from their movements.

[0084] The invention also provides a piece of jewelry comprising a device as described above and intended to be worn by the user, in which the light emitter comprises a light-emitting diode associated with at least one gem made of crystalline material.

[0085] Thus, the user benefits from the fact that he does not have to add an additional device to himself: the jewel acts as a communication device by light emission, while retaining its conventional aesthetic and / or symbolic function.

[0086] The term "light-emitting diode" preferably refers to an LED (for "light-emitting diode"). It allows light emission to be generated efficiently and economically. The LED can also be used for LiFi or infrared communication, or for other types of light communication. Indeed, the modulation of the light intensity of an LED can be carried out very quickly, at frequencies imperceptible to the human eye.

[0087] By "gem" is meant any jewelry stone, natural or synthetic, known in the field of jewelry. The jewel thus appears, from the outside, as a classic jewel to the eyes of the user and third parties. This gem made of crystalline material allows, in addition to the conventional aesthetic and / or symbolic effect of jewelry, to diffuse the light emitted by the diode for the wearer of the jewelry. Thus, when the light emission is generated, it is, from the outside point of view, the jewel that emits the light at the level of the gem, which allows an aesthetic and interesting user experience in addition to being functional and effective.

[0088] This crystalline material preferably has a high refractive index to promote the diffusion of light emission, as well as optical, mechanical, thermal and dielectric properties suitable for communication by light emission within a device worn by the user. Among the materials meeting these criteria, there is synthetic diamond, mono or polycrystalline, formed by a process called "HPHT" (for "high pressure high temperature) or CVD (for "Chemical vapor deposition"). It can also be corundum (synthetic sapphire or ruby), synthetic spinel, synthetic alexandrite, moissanite, zircon, yttrium aluminum garnet crystal.

[0089] Advantageously, the gem is made of synthetic diamond obtained by chemical vapor deposition.

[0090] Thus, the device takes advantage of the properties of this material, described below.

[0091] The synthetic diamond obtained by CVD has remarkable dielectric properties, in particular a low dielectric constant of 5.7, a loss tangent of less than 0.00005 at 145 Ghz and a high dielectric strength of 1,000,000 V / cm, which is particularly relevant in the context of a communication device having electronic means and in particular wireless communication means. In particular, this facilitates the transmission of wireless communications.

[0092] Synthetic diamond obtained by CVD has an extremely high thermal conductivity of 20 to 25 W / cmK. It has a Debye temperature of 2220 K considering a sound speed of 17,500 m / s. This gives it very interesting thermal dissipation properties, in particular in relation to the electronic means of the device, especially since the device is intended to be worn by the user, in particular in contact with the user's skin.

[0093] The synthetic diamond obtained by CVD can be cut and set in a setting so as to be easily integrated into a housing provided for this purpose, offering a desired visual effect to the user.

[0094] This material also exhibits broadband transparency, from ultraviolet to far infrared. This makes it a versatile material with regard to the different possible communication modes, in particular if the device has LiFi or infrared communication means and typically for communication by SWIR waves.

[0095] This material also has excellent acoustic velocity (17,500 m / s), which is useful if the device contains means for receiving voice commands.

[0096] Preferably, the gem comprising an upper part comprising a crown and a table, intended to diffuse the light emission for the user and a part forming a pavilion and located under the crown, the jewel also comprises:

[0097] - a lens taking shape around the pavilion;

[0098] - a light guide connecting the diode to the lens.

[0099] Thus, the guide directs the light towards the crystalline material of the gem at the location desired, for example in a centered manner. This allows for optimized light diffusion in the gem, especially if the diode is off-center relative to the gem. The guide also allows the light from a single diode to be directed into multiple gems if necessary.

[0100] The lens is for example a Fresnel lens formed from a grooved micro-structured polymer film. It can be made by 3D printing. Alternatively, the lens is a diffusion lens forming a film making it possible to highlight the faceting of the gem or to create a pattern projected by the light emission. These light guides and lenses not only make it possible to add visual effects, but also make it possible to optimize the propagation of the light and the colors of the LED diode in the gem so that the refraction of the gem itself and of the incident light are preserved, diffused homogeneously, or even amplified depending on the environment.

[0101] Advantageously, the jewel forms a ring comprising:

[0102] - a ring provided with a through hole,

[0103] - an electronic module for controlling and supplying the diode,

[0104] - the module, the diode and the gem being inserted into the through-hole so as to that a user's finger inserted into the ring is located under the module, the diode and the gem.

[0105] Thus, the through-hole, in which the gem, the diode and the module are housed, allows good radio-frequency operation, in particular if the ring is metallic, by forming, thanks to the gem, a transparent window towards the outside of the ring. This arrangement avoids the effect of the Faraday Cage.

[0106] In particular, when the gem material is CVD diamond, the orifice in the ring allows for a further improved speed of propagation, reflection and transmission of waves due to the low dielectric permittivity of this material.

[0107] A piece of jewelry is also provided comprising:

[0108] - a light-emitting diode;

[0109] - a gem made of crystalline material, the gem comprising a portion forming crown and intended to diffuse a light emission from the diode;

[0110] - a diode power supply and control module,

[0111] - a through hole, in which the module, the diode and the gem are housed.

[0112] A light emission transmitter is also provided comprising:

[0113] - a light-emitting diode;

[0114] - a gem made of crystalline material, the gem comprising a portion forming crown and intended to diffuse a light emission from the diode, the gem also comprising a part forming a pavilion and located under the crown;

[0115] - a lens taking shape around the pavilion;

[0116] - a light guide connecting the diode to the lens.

[0117] A method for filtering user requests is also provided, comprising the following steps:

[0118] - From a learning base including:

[0119] ** past requests, issued by a main device, intended for a user reader,

[0120] ** data defining a context of these requests, and

[0121] ** commands passed from the user to the main device in response to these requests,

[0122] learning, by an artificial intelligence model, of criteria for filtering requests intended for the user based on the data defining the context;

[0123] - reception by the main device of a request sent by a device secondary;

[0124] - filtering the request based on the learning carried out, so as to emit or no, by the main device, the solicitation to the user.

[0125] Advantageously, the stress emitted by the main device is formed by a light emission. Brief description of the figures

[0134] [Fig.l] shows a light emission communication system 1. It is intended to enable a user 3 to be solicited by light emissions in accordance with methods 100 and 200 described below. This system 1 comprises a first device 5 in the form of a conventional smartphone. It comprises a second device 7 in the form of a smart jewel capable of communicating by light emission. It comprises a CLOUD platform 8. Finally, it also comprises a mesh network 9 of other smart devices. Also shown in this [Fig.l], outside of system 1, is a mobile application store 11 (“app store”) where applications intended for the first and second users are hosted. second device. Alternatively, there could be two separate app stores, one hosting apps for the first device 5, the other for the second device 7.

[0135] The smartphone 5 is conventional. It is therefore equipped with conventional wireless communications means and a conventional microprocessor, and conventional data storage means. It has in its memory a mobile application 13 downloaded from the application store 11. These elements allow it to implement the part that concerns it of the method 100 described below. In particular, the smartphone 5 plays the role of intermediary, via the mobile application 13, between the CLOUD platform 8 and the smart jewel 7.

[0136] The mobile application 13 comprises in recorded form a computer program 14 comprising instructions which, when executed by a computer, here by a processor of the smartphone 5, lead the latter to implement the steps of the method 100 described below.

[0137] The CLOUD platform 8 presents a CLOUD infrastructure of the AWS type (for “Amazon Web Services”). It presents training means, in particular a processor, of an artificial intelligence model which, trained from the commands placed by the user 3 in response to corresponding past light emissions generated by the jewel 7 and from the corresponding past requests sent by the smartphone 5, determines and refines request filtering criteria according to the context of these requests, in order to decide whether or not to submit them to the user 3. This model also determines and refines the content of the light emissions to be generated by the jewel 7 for the user 3 also according to these elements. This model is updated and communicated regularly by the platform to the application 13 of the smartphone 5 which transfers it to the firmware 61, mentioned below, of the jewel 7.More generally, the platform 8 is configured to receive data emitted by the smartphone 5, this data regularly coming from the jewel 7, and to process it on servers. Once the processing is complete, the results of its processing are sent to the application 13 of the smartphone 5 and possibly transferred to the jewel 7. The results provided may be predictions, classifications, analyses, or any other output specific to the task assigned to an artificial intelligence model. The platform 8 communicates with the mobile application 13 of the smartphone 5. This platform 8 therefore includes means of communication, in particular means of communication via the Internet. Each new feedback from the user 3, retrieved by the jewel 7, is transmitted to the CLOUD platform 8 by the application 13 of the smartphone 5 to update the artificial intelligence model by the cloud platform 8.The CLOUD 8 platform also includes calls to APIs (for "Application Interface Programming") of third-party services. way of allowing light emissions to be generated by the jewel 7 depending on third-party applications.

[0138] The platform 8 comprises in recorded form a computer program 16 comprising instructions which, when executed by a computer, here by the platform, lead the latter to implement the steps of the method 100 described below.

[0139] The mesh network 9 represents one or more third-party devices communicating with the smartphone 5 and / or the jewel 7. These may be conventional smartphones, other smart jewels equipped, like the jewel 7, with light emitters capable of generating light emissions in accordance with the methods 100 and 200 described below, or any other devices intended to communicate with one of the devices of the system.

[0140] The connected jewel 7 is illustrated schematically in figures 2 to 5. It forms a ring.

[0141] This ring 7 comprises a metal ring 15 provided with a through orifice 17. Alternatively, the ring could be made of another composite material, for example ceramic.

[0142] This ring 7 comprises, in the orifice 17, a light-emitting diode 19 of the LED type. The diode 19 is capable of generating a light emission. This light emission is colored, the term “colored” including black and white. The diode 19 can generate an emission that changes color. The diode 19 is capable of emitting LiFi or infrared waves, in particular SWIR waves. Alternatively, it could only emit conventional light waves. As a variant, the ring may have several diodes.

[0143] The ring 7 also comprises in the through-orifice 17 a gem 23 made of synthetic diamond obtained by chemical vapor deposition (or CVD). Alternatively, the gem could be made of another crystalline material. This gem 23 comprises an upper part, comprising a crown 25 and a table 29, intended to diffuse the light emission for the user 3 and a pavilion-forming part 27 and located under the crown 25. As illustrated in FIGS. 4 and 5, these two parts merge at the outer end of the ring 15. The crown 23 has the shape of a rectangular parallelepiped whose table 29, forming the upper end of the gem 23 and protruding from the ring 15, is smaller than the area occupied by the parallelepiped at the outer surface of the ring 15.The pavilion 27 has the shape of a triangular prism oriented so that one of its edges forms the lower end 31 of the gem 23 within the orifice 17. The ring 7 also comprises a lens 33 taking shape around the pavilion 27, that is to say occupying its side walls. This is a lens. called "Fresnel" made of grooved microstructured polymer film. Alternatively, it can be a lens made of any film or material. The ring 7 also comprises a light guide conduit 35 connecting the diode 19 to the middle of the lower end 31 of the gem 23, so as to optimize the diffusion of the light emitted by the diode 19 within the gem 23.

[0144] The gem 23, associated with the diode 19, thus forms a light emitter of the ring 7 making it possible to generate light emissions intended for the user 3.

[0145] Alternatively, the ring 7 could have several gems. In this case, each gem could be associated with one or more diodes, or conversely, a diode could be associated with several gems. The ring could then have several orifices, each comprising the elements described above.

[0146] Alternatively also, the gem 23 could be made of another material. It is however advantageous for the material to have dielectric characteristics similar to those of synthetic diamond obtained by CVD, to promote wireless communications, similar optical characteristics to promote the diffusion of the light emission, similar thermal characteristics to promote the integration of the module, the diode, and the comfort of the user, as well as similar acoustic characteristics to promote the reception of voice commands.

[0147] Alternatively, gem 23 could have any other shape. In addition, it could be pavilion-free, like rosecut gems.

[0148] The ring 7 also comprises in the through-orifice 17 an electronic module 21 for controlling and supplying the diode 19, capable of supplying the diode and triggering the light emission in accordance with a determined content and as a function of data to be processed. This module 21 takes the form of a flexible printed circuit extending into the orifice 17. It comprises a battery 36 for supplying power to the components. This module is not limited to the control and supply of the diode 19 but also supplies and controls the components described below. The module 21 comprises a motion sensor 37 comprising an accelerometer and a gyroscope, to identify predetermined movements of the jewel 7 forming commands from the user 3, a microphone 41 of the MEMS type (for "Micro-Electro-Mechanical System") associated with a pre-amplifier, to receive voice commands from the user 3, and a loudspeaker 43 for possible voice requests by the jewel to the user 3. This module 21 also comprises wireless communication means 45 comprising a radio antenna 47 configured to communicate via Bluetooth with another device. It could be configured to operate according to another protocol. These means 45 also comprise a device 49 for transmitting / receiving waves infrared, capable of communicating in SWIR waves, and a device 51 for transmitting / receiving LiFi waves. These devices 49 and 51 are associated with the LED 19 for the transmission of these waves, in particular to modulate the transmissions. In a variant, these devices are distinct from the LED 19 and have their own transmitters. This module 21 also comprises a piezoelectric energy harvester 53 for recovering energy from the body of the user 3 wearing the jewel 7 and / or from the movements of the jewel 7 and for storing this energy in the battery 36.

[0149] This module 21 finally comprises a microcontroller 55 for controlling all of the elements described. This microcontroller 55 is associated with a memory 57 of conventional form, comprising in recorded form a computer program 59 comprising instructions which, when executed by a computer, here by the microcontroller 55, lead the latter to implement the steps of the methods 100 and 200 described below. This program is downloaded from the application store 11 or from any recording medium comprising the program.

[0150] The microcontroller 55 communicates with a “firmware” 61 containing an artificial intelligence model 63 updated regularly by the CLOUD platform 8. A firmware is a “firmware”, or “microprogram”, which can also be called “internal software” or “embedded software”, formed by a program integrated into computer hardware and corresponding to a low layer, in particular lower than the conventional application layer, according to the OSI model. It is here integrated into the printed circuit of the module 21. The artificial intelligence model 63 makes it possible to process the requests received in accordance with the methods 100 and 200 described below. The firmware 61 also integrates software libraries necessary for the execution of the artificial intelligence model 63.In particular, this artificial intelligence model 63 makes it possible to locally filter the requests to be emitted or not in the form of light emission for the user 3 according to filtering criteria learned by the model 63, to locally process the development of the content of the light emission to be generated and to process the feedback from the user 3 by voice command or movement of the jewel 7. This local management makes it possible to improve the processing speed, the confidentiality of the data and reduce the dependence on an Internet connection. The artificial intelligence software layer can also manage the optimization of the energy of the ring 7 or perform other assigned tasks. Alternatively, all or part of this layer can be integrated into the CLOUD platform 8 and / or the smartphone 5. .

[0151] All or part of the software layers described, integrated into the jewel, can be considered as forming an “intelligent assistant”.

[0152] The module 21, the diode 19 and the gem 23 are inserted into the through-hole 17 so that a finger of the user 3 inserted into the ring 15 is located under the module 21, diode 19 and gem 23.

[0153] All of these elements implement the method 100 described below.

[0154] The first steps are preliminary steps to the heart of the process.

[0155] In step 101, the dedicated mobile application 13 is downloaded from the application store 11 and installed on the smartphone 5.

[0156] In step 102, the smartphone 5 is paired, via its means and through the mobile application 13, to the smart ring 7. By “pairing”, or “peering” in English, we mean the operation allowing two devices to open a wireless connection between them, after a co-identification step, so as to exchange data between them subsequently. The communication between the smartphone 5 and the ring 7, established by pairing, is implemented by Bluetooth.

[0157] In step 103, the user 3 indicates, by the mobile application 13 of his smartphone 5, preferences concerning the way in which the light emissions must be generated by the jewel 7. This involves in particular defining, for requests concerning calls or messages, so-called priority people, that is to say for whom light emissions must be generated for the user 3 even if the user is considered busy. It also involves associating light patterns for these people, and / or specific color shades, so as to allow the user 3 to identify from the light emission which person is requesting him. It may also involve defining categories of message subjects and associating them with particular light emission shades, and / or defining priority levels for the requests and associating them with particular emission patterns.This configuration is then transmitted to the connected jewel 7 so as to update the model 63 integrated into its firmware 61. This step 103 is completely optional. It is in fact possible to let a default configuration generate the first emissions while the artificial intelligence model 63 is updated as the user 3 responds to these emissions.

[0158] In step 104, the steps forming the communication by targeted light emission begin. A request is sent to the smartphone 5, intended for the user 3. In this example, this is an “SMS” type message. It is sent by a third-party device not illustrated, for example by a friend of the user 3 who is not listed as a priority contact. Alternatively, this request could be a call received by smartphone 5 intended for the user 3 or a notification from the smartphone 5 intended for the user 3 and relating for example to an event, a location, a moment or an activity. Any other type of request intended for the user 3 can be envisaged.

[0159] In step 105, instead of warning the user, via a notification, a noise or a another type of direct solicitation, the smartphone 5 sends this solicitation, i.e. the SMS, via Bluetooth, to the smart jewel 7. This solicitation, i.e. the signal relating to this SMS, is sent in parallel to the CLOUD platform 8 which records it for the purpose of future updating of the artificial intelligence model and / or particular processing, for example a subsequent analysis of the content of the message.

[0160] In step 106, the jewel 7 performs a step of filtering the request, so that the light emission is implemented only when it is determined in the filtering step that the request is relevant for the user 3. The filtering criteria are determined by the artificial intelligence model 63 trained on the CLOUD platform 8 from the commands placed by the user 3 in response to past corresponding light emissions and to the past corresponding requests. As already mentioned, the model 63 is regularly updated and communicated to the jewel 7. These filtering criteria concern for example one of the following elements:

[0161] - a type of element on which the stress is applied, for example if it is a message, a call, a notification. In this example, it is an SMS.

[0162] - a content of the message or notification;

[0163] - a moment of reception of the solicitation by the jewel 7. Depending on the soli quote, model 63 can predict the generation of the light emission at a more favorable time.

[0164] - a place where the jewel 7 is located. This place is identified in particular by the smartphone 5 which communicates with the jewel 7. Alternatively, the jewel 7 itself could have geolocation means.

[0165] - an ongoing activity of user 3 identified by the jewel 7. This activity is identified by the jewel 7 according to commands from the user 3 or according to data sent by the smartphone 5.

[0166] This list is not exhaustive and other filtering criteria can be established. The criteria can be chosen by the user 3 or learned by the model 63. In the present example, the SMS successfully passed the filtering step.

[0167] Alternatively, this filtering step could be carried out by the platform 8 and / or the smartphone 5 via the application 13. The result would possibly be transmitted to the jewel 7.

[0168] In step 107, the jewel 7 prepares the content of the light emission, formed according to the request received. This preparation is carried out by the artificial intelligence model 63 integrated into the firmware 61 of the jewel 7 and updated regularly by the CLOUD platform 8. In the present example, the model 63 assigns a category to the SMS from among the following categories: “social”, “family”, “work”, “games and other entertainment”, “others”. Other categories could be defined by the user 3 or learned by the model. The chosen category corresponds a hue is selected by the user 3 in step 103, or provided by default or learned by the model 63. The model 63 also assigns a pattern of the light emission, that is to say a variation over time of the saturation and / or the brightness, depending on the degree of priority of the request. This pattern is for example a more or less rapid and more or less pronounced flashing, or any other specific variation of saturation and / or brightness of the light emission. The degree of priority depends on numerous criteria, which may include the same context criteria as those used for the filtering step, and / or other criteria learned by the model. These may also be criteria defined by the user 3. In particular, three levels of priorities may be provided, a number which allows the user to easily remember the corresponding patterns.

[0169] Alternatively, this step of preparing the content of the light emission could be carried out by the CLOUD platform 8 and / or by the application 13.

[0170] In step 108, the jewel 7 generates the light emission prepared in step 107, for the user 3. Thus, the diode 19 emits the prepared emission, that is to say with the selected hue and in accordance with the saturation / luminosity pattern evolving over the determined time. This emission is diffused by the gem 23 for the user 3.

[0171] At step 109, the user, who saw the light emission generated by his jewel 7, understood its meaning. This step is then the reception, by the ring 7, of a command from the user 3 in response to the light emission. In the present example, the user 3 understood thanks to the color and the pattern of the emission, that he had received an SMS from a friend, this SMS being associated for example with a medium priority, or second level among three levels. Finding the appropriate request, that is to say relevant both in the present context, and in its content, he chooses to perform a “tap” with his finger wearing the ring 7, that is to say a sudden downward movement also stopped abruptly, to inform the jewel 7 of this relevance. This movement is generally associated with the fact that user 3 is going to read the text message on smartphone 5. This movement is identified by the accelerometer and the gyroscope of ring 7.Alternatively, User 3 could have indicated a relevance level from among the following two other levels: .

[0172] - irrelevant broadcast;

[0173] - irrelevant broadcast due to the context in which it was generated, the context being for example defined by data on the time and / or location and / or current activity of the user.

[0174] Other types of feedback are possible. The user can, for example, indicate that he wants the smartphone 5 to delete the received SMS. The user could just as easily formulate, by his command, a response to the request, the response being intended for the sender of the SMS, for example via a predefined message corresponding to a gesture.

[0175] The user's gesture may have been previously associated with a command, or this association may be learned by the artificial intelligence model 63 recorded in the firmware 61 of the jewel 7.

[0176] Alternatively, the user's command may be vocal. It is then received by the MEMS microphone of the jewel 7.

[0177] In step 110, the user's command made in response to the light emission, whether gestural or vocal, is communicated by the jewel 7 to the smartphone 5 via the application 13, by Bluetooth. The smartphone 5 then transmits this response to the CLOUD platform 8, which records it and associates it with the previously recorded SMS.

[0178] In step 111, the CLOUD platform 8 updates the artificial intelligence model 63 on the basis of this new data: the initial request, the content of the light emission formed, the feedback from the user. The updated model is then sent to the smartphone 5 which transfers it to the jewel 7. The model therefore takes into account the feedback from the user 3 as it goes along to improve the filtering of future requests and the content of these requests. This type of update can be ordered or occur at different time intervals, regular or not.

[0179] Several alternative modes of implementation, not illustrated, of this method based on the mesh network 9 will now be described. In these alternative modes, several light emission devices comprising the means of the ring 7 may be brought to communicate with each other. These communications are carried out by Bluetooth, but may also be carried out via the LiFi or infrared communication means described above. These communications may also be directly formed by the light emissions.

[0180] In the first alternative mode, the mesh network 9 comprises one or more other jewels worn by the user 3. At the time of the pairing step 102, the smartphone 5 detects several jewels via the application 13. The pairing can then be carried out with a set formed by these jewels, or with one of these jewels, which is in turn paired with one of the other jewels and so on. The jewels can be configured to act differently. For example, professional requests can be the subject of emissions by only one of the jewels, while personal requests are processed by another jewel. In another example, the same request can be distributed over all of the paired jewels or over some of them, resulting in a light emission, generated by several jewels in a coordinated manner.

[0181] In a second alternative mode, the mesh network 9 is closed, that is to say that it relates to a well-defined entity, the devices in the network have similar characteristics, and it is not open to the outside. Several users wear smart jewelry or other devices equipped with light emitters capable of generating emissions in accordance with the methods 100 and 200 described, paired with each other within the closed mesh network 9. It is then possible to set up a specific configuration of the light emissions. For example, within a company, a shade may correspond to a given department, while the pattern, i.e. the variation in saturation / brightness time, may correspond to a specific situation in the department. The recipients of the company seeing the light emission, in particular on their own jewelry, therefore understand that they are being requested for this specific situation concerning this specific department.This type of communication is particularly advantageous in a so-called "no-phone" setting, that is, where the use of telephone communication is prohibited or limited. The source information forming the initial solicitation for the jewelry may also be a device other than a smartphone. The same type of configuration may concern a family. Specific content may, for example, be associated with a specific message concerning a specific member of the family. As another non-limiting example of solicitation between several pieces of jewelry within a closed network, a pink light emission with a pattern reproducing a heartbeat may correspond to a message sent by a romantic partner.

[0182] A third mode of implementation concerns the mesh network 9, but this time open to other types of devices not necessarily equipped with light emitters conforming to the methods described. In particular, other connected or so-called "intelligent" objects can communicate with the device described, for example with the ring 7, provided that a language has been agreed upon. As a non-limiting example, a medical bracelet, without screen or light emitting device, worn by the user, can send a request, concerning medical data of the user, directly to the ring 7. The ring 7 filters and generates, if necessary, a light emission relating to this request, for the user. The ring therefore allows the user to become aware of data emitted by the bracelet.

[0183] In these embodiments, the smart devices can exchange with each other without a request being immediately generated by light emission. For example, a first device of a user can request from a second device of another user a later reminder of a request, which is returned by the second device only in a specific context.

[0184] It is recalled that in all the embodiments described, a method 100 of communication by light emission with a user is implemented, comprising the following steps:

[0185] - by wireless communication, sending, from a first device to a second device, of a solicitation intended for the user,

[0186] - preparation of a content of a light emission formed as a function of the solli quote,

[0187] - generation of the light emission, by the second device, for the purpose of the user,

[0188] - reception, by the second device, of a command from the user in response to light emission.

[0189] Therefore, in a light emission communication device such as the ring 7, and with reference to [Fig.7], a method 200 for generating a light emission is implemented, the method comprising the following steps:

[0190] - a step 201 of reception, by wireless communication means of the device, of a solicitation intended for a user,

[0191] - light emission formed as a function of the stress having been prepared, a step 202 of generating the light emission, by a light emitter of the device, for the user,

[0192] - a step 203 of receiving, by means of receiving a command from the device, of a user command in response to the light emission.

[0193] The invention is not limited to the embodiments presented and other embodiments will become clear to those skilled in the art.

[0194] In particular, instead of the ring 7, any device comprising a light emitter and capable of generating a light emission in accordance with the methods described is concerned by the invention. Among these devices, any device that can be "put on" by the user is advantageous, i.e., one that the user can equip himself with without then having to hold the device in position by an active effort. This may be, for example, pins fixed to a garment of the user, or even devices integrated into the garment, accessories put on by the user or worn, on the head, around the neck or in any other way that avoids the user having to make an effort, for example avoiding him having to hold the device by shaking his hand. Among the jewels integrating this light emitter, such as the ring 7, any jewel is conceivable.By way of non-limiting examples, the device comprising the electronic module 21 and the diode 23 can be integrated into a necklace, a bracelet, a set, an earring, by associating these elements with a gem, whether it is made of crystalline material or not.

[0195] The smartphone 5 could be replaced by any other device capable of sending requests to the light-emitting device. This could be a computer, a tablet, but also any so-called “intelligent” assistant integrated into a device, portable or not. It could also be any device in a city connected, NEOM type. As already mentioned, it can also be another light-emitting device. In an embodiment where the platform 8 would send information directly to the jewel, it is the relevant server of the platform which plays the role of the device sending the request.

[0196] As already mentioned, the artificial intelligence model can be integrated into the firmware of the light emitting device, or operate only on the CLOUD platform or even on the mobile application. The filtering step and the step of forming the content of the light emission can therefore be carried out by the light emitting device or by another entity. List of references
