Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the fields of security and entertainment, and more particularly to the field of portable electronic devices configured to be worn by users at a popular event. The present invention also relates to a communication method using a plurality of said portable electronic devices.

STATE OF THE ART

In a context of digital adventures, the entertainment industry must adapt to offer viewers an ever more enriched and secure experience.

Technologies exist that allow each user to be no more than a mere spectator of an event, but to become an actor. Today, these technologies generally use portable electronic devices equipped with optoelectronic components, such as light caps or other miscellaneous and varied accessories. These devices emit light in a preprogrammed manner or in a manner dependent on a circumstantial parameter captured, such as a movement of the wearer.

At the same time, the "dematerialisation" of event tickets seems to be increasingly accepted and more and more expected by the spectators. Indeed, thanks in particular to the NFC (for "Near Field Communication" technology according to the English terminology), we see emerge the use of electronic tickets contained in accessories such as bracelets. For example, they are uniquely associated with a given event, such as a concert or an exhibition, and are decorated so that they participate in the identity and promotion of the event. These devices also provide additional security appreciated by event organizers. They effectively provide more secure and faster control of access to an event. However, they do not provide any control after this access.

In terms of event security, it must be admitted that the success of an event is strongly correlated with the absence of incidents among spectators, or at least the minimization of these incidents by their prevention and the reactivity of the security services. in case of occurrence of these incidents. Except, currently, no technology has yet proposed a solution that is simple, functional and discreet to solve security problems, especially in a crowd.

In this context, note that it would be profitable for emerging technologies to allow each user to become a player in event security.

Thus, each of the technologies discussed above have very strong limitations as to the experience and safety of its user. Indeed, the interaction they offer is limited and only satisfies users who are constantly looking for new experiences. And the problem of event security, and more particularly of the security of each spectator, remains whole for the organizers.

The present invention attempts to respond, at least in part, to at least one of the aforementioned problems.

SUMMARY OF THE INVENTION

The present invention relates to a portable electronic device comprising at least one flexible electronic circuit and a flexible envelope in which the flexible electronic circuit is housed, the flexible envelope being intended to be fixed at least partly around a body part of a user, the flexible electronic circuit being configured to functionally support a plurality of electronic components including at least one power supply module, at least one microcontroller, at least one non-transitory information storage medium, at least one first radio communication module frequency to communicate on a first distance, and at least a second radio frequency communication module clean to communicate on a second distance with a remote computer server, said second distance being greater than said first distance.

For example, in the context of safety, the heart rate, the electrical resistivity of the epidermis, but also the ambient sound, the movements of the user, are all parameters that can help to adapt the stimuli generated by the portable electronic device. For example, it is possible to trigger a series of bright animations so as to visually locate a particular user in a moving crowd. It is still possible that each user located near a user to locate participates in this location via their portable electronic device.

In the context of entertainment as well as event security, the portable electronic device makes it possible, for example, for each user to make a pixel and, in a crowd, a distribution of pixels thus achieving a "support" at least visual of which each user is actor. Thus, the measurements collected at the level of each user can be analyzed so as to restore an experience enriched and still unmatched for each user who, from simple spectator of a show, becomes an actor, and so to better ensure the safety of each user even "drowned" in a compact crowd.

The present invention thus makes it possible, through a device increasing the experience of a show, to secure at the same time each spectator or set of spectators by detecting danger situations.

DETAILED DESCRIPTION OF THE INVENTION

In the context of the present invention, the term "flexible" or "flexible" the property of an element thus qualified to bend easily to espouse the particular shape of the body part of the user around which said element is intended to be fixed. When said element is an electronic circuit, its property of flexibility must be sufficient not to alter these functionalities when the portable electronic device which comprises this electronic circuit is fixed according to the intended use around the body part of the user.

As illustrated in FIG. 3, the portable electronic device 1 comprises at least one flexible electronic circuit 11 and a flexible envelope 12 in which the flexible electronic circuit is housed. The flexible envelope 12 housing the flexible electronic circuit 11 is intended to be fixed at least partly around a body part of a user. For example, the envelope may comprise a fabric, leather or plastic or silicone or polymer ribbon. The envelope preferably comprises a fixing device 123 to enable the portable electronic device to be removably fixed around a body part of the user.

As illustrated in FIG. 2, complementary self-gripping strips 123 may be fastened in series on one end of the ribbon constituting part of the envelope, and a groove 123 may be made in the other end of said ribbon, so that one can, by passing the self-gripping band the most distal through the groove, fold this band on the other complementary to come fix the tape around a wrist in the manner of a bracelet, around the arm to the like an armband or around the head like a headband. It should be noted that the envelope does not necessarily constitute the totality of a bracelet, an armband, a headband or any other type of clothing accessory, but may only constitute a part of it. The flexible envelope 12 makes it possible to house the flexible electronic circuit in particular so that, if necessary, the latter is in direct contact with a body part of the user only in a controlled manner and for functional purposes. It may indeed be useful, even functionally unavoidable, that part of the flexible electronic circuit 11 or components that it supports is in direct contact with a body part of the user; this is for example the case when it is desired to measure certain physiological characteristics of the user. The flexible envelope 12 is intended to protect the flexible electronic circuit 11 and the electronic components that it supports external aggressions may deteriorate, such as the perspiration of the user or rain. The envelope also aims to protect the user from any undesirable contacts, for example for reasons of safety, hygiene or comfort, with all or part of the flexible electronic circuit and the electronic components that it supports. The flexible envelope 12 may comprise an opening through which the flexible electronic circuit 11 can be inserted into the envelope or extracted from the envelope. Thus, the manufacturing, possibly industrial, of the flexible envelope 12 and the flexible electronic circuit 11 may be performed separately, the portable electronic device 1 being assembled later easily.

The flexible electronic circuit 11 is configured to functionally support a plurality of electronic components. The term "functionally support" means that the electronic components are not necessarily all supported directly on a printed circuit of the flexible electronic circuit 11, but can also be connected wired or wireless connection, for example of the "Bluetooth" type. To the printed circuit of the flexible electronic circuit 11. This will for example be the case when the envelope constitutes all or part of a strip and that one of the electronic components functionally supported by the flexible electronic circuit, high speakers or headphones connected by wires to the flexible electronic circuit and intended to be housed in the ears of the user.

The flexible electronic circuit 11 may comprise: a flexible printed circuit, for example made from thin insulating material, very often polyimide, and / or polyester (PET polyester or polyester naphthalate said PEN) silkscreened with silver and / or Polyetheretherketone (PEEK) and / or flexible epoxy glass and more generally based on any known technology today or tomorrow by the skilled person to achieve a flexible printed circuit. a circuit called "flex-rigid" comprising flexible parts and rigid parts, the flexible parts electrically connecting the rigid parts to each other and the rigid parts supporting electronic components. The flexible parts may possibly support electronic components.

As illustrated in FIG. 1, the flexible electronic circuit 11 may, for example, comprise three rigid or flexible printed circuits interconnected by flexible wire layers, the latter being represented in FIG. 1 by the hatched zones. It is better understood in the illustrated example the flexibility constraint that must comply with the flexible electronic circuit 11 according to the invention; in this case, the flexibility required is essentially flexural flexibility in the length of the flexible electronic circuit 11 and no torsional flexibility is required for example to allow the flexible electronic circuit 11 to come at least partially to marry the general shape of the body part of the user around which the portable electronic device is intended to be fixed.

As illustrated in FIG. 1, the flexible electronic circuit 11 supports, for example directly, in addition to a standard activation button, at least one power supply module 111, at least one microcontroller 112, at least one information storage medium non-transient 113, at least a first radio frequency communication module 114 adapted to communicate over a first distance, and at least a second radio frequency communication module 115 adapted to communicate on a second distance with a remote computer server.

The term "power supply module" is a connector intended to accommodate a corresponding energy storage device 3, or such a connection and the corresponding energy storage device 3. In either case, the use of a rechargeable battery with or without contact as an energy storage device is preferred. It may more particularly be a rechargeable capacitive storage device with or without contact.

In particular with the aim of enabling contact recharging of an energy storage device, the flexible electronic circuit 11 may furthermore comprise a connection port 116, for example a connection port known as "micro-USB" Or more generally any type of USB connection. According to the embodiment illustrated in FIG. 1, the connection port 116 is supported by the central part of the flexible electronic circuit 11; according to the embodiment illustrated in Figure 4, the connection port 116 is supported by a distal portion of the flexible electronic circuit 11. The same is true of all the electronic components functionally supported by the flexible electronic circuit; their location may be different from that shown in the figures. In particular, it is possible for at least one printed circuit of the flexible electronic circuit 11 to be a so-called double-sided printed circuit capable of supporting electronic components on each of these faces. Be that as it may, the proper distribution of electronic components on a printed circuit is considered to be the ordinary practice of an electronic circuit designer and, in this respect, the locations of the electronic components as illustrated in Figure 1 are in no way limiting.

The connection port 116 may also be connected to the non-transitory information storage medium 113 to enable the portable electronic device 1 to be connected to a digital device, for example a smartphone or a personal computer, so as to enable them to exchange Datas.

The term "remote computer server" means communication and data processing means that can be summarized to one or more computers, but these means can also involve the implementation of relay antennas or a computer organization model for the access to digital resources whose storage is outsourced to multiple servers, such a model being known under the name "cloud" Anglo-Saxon.

Preferably, and as illustrated in FIG. 5, the second distance d2 over which the second communication module 115 is able to communicate is greater than the first distance d1 over which the first communication module 114 is able to communicate; it is understood that the first and second radio frequency communication modules supported by the portable electronic circuit 11 are called to play different roles in the implementation of the portable electronic device 1. Moreover, the first radio frequency communication module 114 is preferably an NFC module whose range can reach a few tens of centimeters; and the second radio frequency communication module 115 is preferably a Wi-Fi module whose range can reach several tens of meters. The first radio frequency communication module 114 can also be a Bluetooth or radio frequency module whose range is a few meters. The second radio frequency communication module 115 can also be a GSM or radio frequency module whose range is several hundred meters.

According to the embodiment illustrated in FIG. 5, the portable electronic devices 1b, 1c and 1d are in the coverage area of the first radiofrequency communication module of the portable electronic device 1a, this coverage area being illustrated by the dashed circle. short centered on the portable electronic device la. The portable electronic devices and If being located outside the coverage area of the first radiofrequency communication module of the portable electronic device 1a can not directly communicate thereby with the portable electronic device 1a. However, it is possible for the portable electronic devices to communicate with each other via the portable electronic device 1d located at a distance from the portable electronic devices 1a and the lower one at the distance d1.

The area of coverage of the second radiofrequency communication module of the portable electronic device If is represented by a long dashed circle centered on the portable electronic device If. The remote computer server 2 is in this coverage area and the portable electronic device If is then able to communicate directly with the remote computer server 2. On the contrary, the portable electronic device 1g can not communicate with the remote computer server 2 which is at a distance greater than the distance d2. This incapacity can, however, be easily solved by means of a relay antenna 4 properly located between the portable electronic device 1g and the remote computer server 2. A plurality of relay antennas 4 can be distributed at the location of a relay event. so that each portable electronic device can communicate with the remote computer server 2 regardless of its location at the place of the event.

According to another advantageous embodiment, the portable electronic devices surrounding the portable electronic device 1g can be used to relay the information from the portable electronic device 1g to the relay antennas or directly to the remote computer server 2. According to this embodiment, each portable electronic device provides a function of relaying information from and to the portable electronic device 1g, this situation is advantageous when one or more portable electronic devices are at a distance too great to communicate with relay antennas but at a sufficient distance to communicate with other portable electronic device that they are able to communicate with relay antennas or directly with the remote computer server 2. According to this embodiment, each portable electronic device is a relay for others.

The flexible electronic circuit 11 further functionally supports: - at least a plurality of stimulation modules 13, and - at least a plurality of measurement modules 14.

Each stimulation module 13 may be configured to generate a determined stimulation.

Each measurement module 14 may be configured to measure an environmental or physical parameter of the user.

As illustrated in FIG. 1, said measurement modules comprise at least one of: at least one gyroscope and / or one accelerometer and / or one magnetometer 141 for measuring data relating to the movement of the user carrying the electronic device portable; at least one microphone 142 for measuring data relating to the ambient sound; at least one sensor 143 of a physiological function of the user; at least one action button configured to measure actions and / or expectations of the user, for example when the user wants to share on social networks the fact that he likes what he is doing live, or that he is in distress.

It emerges that each portable electronic device 1 can detect 1100 an anomaly by analysis of measurement data provided by at least one of its measurement modules 14.

More particularly, said at least one sensor 143 of a physiological function of the user may comprise a heart rate sensor, an arterial pressure sensor, a body temperature sensor, a nerve impulse sensor, a resistance sensor. epidermal electric, a sensor of the blood oxygen level. A detectable abnormality is for example a stop of the detection of the heart rate by the heart rate sensor.

Advantageously, said action button makes it possible to perform an action preprogrammed by the user or the organizers of the event.

According to one embodiment, several buttons can be understood by the portable electronic device so that one is dedicated to security issues such as a visual and / or audible warning button to easily locate the user at risk, for example. According to this embodiment, another button can be used to share information on one or more social networks.

This shared information can come directly from the measurement modules and / or the remote computer server 2 and / or stimulation modules.

For example, the three-dimensional trajectory of the portable electronic device over a defined time can be transmitted in the form of an image and / or an animation or a video on the social networks so as to produce an artistic representation of the user during the event.

For example, it is the cardiac data that can be transmitted, for example in the case of a sensational attraction, the user can transmit his cardiac data over a defined period of time so as to illustrate the variations in his heart rate caused by attraction. This can be applied to any measurement collected by the measurement modules.

The present invention then makes it possible to define a new form of expression and representation of information and user experience.

The present invention thus makes it possible to collect a plurality of spatiotemporal and physiological data all linked to an event allowing a new definition of the user experience, as well as a new representation of this event in terms of the user experience.

Events can then be classified according to the level of heartbeats per minute they generated, or the decibels received by viewers, but also by the movements of portable electronic devices, or any other measure considered alone or in combination with 'other.

Organizers can, for example, select the person with the most intense heart rate to give him a gift.

According to another embodiment, these measures can also be exploited by the organizers to reinforce user experiences. For example, if an area of the crowd has physiological data indicating a decrease in heart rate relative to the rest of the crowd, the sound and light equipment in that area can be optimized to increase the heart rate and therefore the user experience.

Advantageously, these measurements of physiological data and the use of stimulation modules can be used to calm or, conversely, to increase the experience of the user.

According to one embodiment, electrical stimulation may be generated at the portable electronic device in order either to relax the user or, conversely, to stimulate his physiological functions if necessary.

As illustrated in Figure 1, said stimulation modules 13 comprise at least one of: - At least a plurality of LEDs 131 to generate visual stimulation; At least one vibration module 132 for generating tactile stimulation; At least one speaker 133 for generating auditory stimulation.

The portable electronic device may further comprise a light guide 121. This light guide may constitute, if necessary, a part of the envelope 12. It is designed to diffuse the light emitted by the said plurality of LEDs 131. This last form of preferably a ribbon of LEDs. Preferably, the visual stimulation generated by said at least a plurality of LEDs may be of a changing color and / or may be polychromic.

The present invention thus makes it possible not only to collect a plurality of data concerning each user and his environment, in particular to detect an abnormality 1100, but also makes it possible to adapt, on the basis of this plurality of data, a plurality of stimuli rendered by the modules for stimulating at least one set of portable electronic devices so as to be perceived by a set of users and / or by the security services, in particular to locate the detected anomaly 1300, to possibly verify its nature and to take and implement the appropriate corrective measures promptly.

In particular, the second radio frequency communication module 115 of each portable electronic device 1 can be configured to send to the remote computer server 2 measurement data collected by at least one of said measurement modules 14. In addition, the second module radio frequency communication 115 of each portable electronic device 1 may be able to receive from the remote computer server 2 pacing data determined according to said measurement data sent to the remote computer server 2. Upon receipt of said stimulation data, the microcontroller 112 of each portable electronic device 1 is able to control the stimulation modules 13 of the portable electronic device according to these data. In this context, it is the remote computer server 2 which processes the measurement data collected.

The remote computer server 2 communicating with each portable electronic device 1 can collect the measurement data sent by a plurality of these devices. These data can thus advantageously be processed crosswise or grouped or individually. Therefore, identical stimulation data adapted to the measurement data collected from the plurality of portable electronic devices 1 can be sent from the remote computer server 2 at least to said plurality of portable electronic devices. This allows a muiti scale analysis both customized for each user, but also by user group and finally at the level of all users.

Also, the security services can exploit the measurement data collected at the remote computer server 2, for example to predict and avoid risky crowd movements or to define areas to be closed to the spectators because of a risky sound exposure. . Similarly, the identification of an individual at risk or conversely representing a danger to other users can be achieved by the present invention.

As an alternative or in combination with the processing of the measurement data by the remote computer server 2, the microcontroller 112 of each portable electronic device 1 may be able to process the measurement data collected by the measurement modules to generate corresponding stimulation data. and control said stimulation modules 13 based on these data. According to this embodiment, the microcontroller can process all or part of the data measured by the measurement modules.

According to one variant, predetermined stimulation data as a function of the measurement data or their evolution can be stored in the non-transient information storage medium 113 of each portable electronic device 1 or in the remote computer server 2. This predetermination of Stimulation data can also be personalized, for example for users who have reported having a pathology, such as heart weakness, asthma or diabetes.

Advantageously, different measurement data can be cross-referenced to determine adequate stimulation data. For example, if the heart rate sensor is measuring a flat electrocardiogram, it may be simply because the user has lost his portable electronic device. On the other hand, if its body temperature sensor continues to indicate a relatively normal body temperature, the correlation of these measurement data may more likely indicate that the user has made a cardiac arrest. If furthermore the user is known to have heart weakness, cardiac arrest can be detected even more reliably.

According to one embodiment, in the case of the detection of a cardiac arrest for example, a series of stimuli can be set up to both locate the user, warn the surrounding users but also, according to one embodiment very particular, try to electrically stimulate the user to restore a stable heart rate through a module of electrical stimulation. Conversely, this electrical stimulation module can be used, according to one embodiment, for the control of a user representing a risk for other users. This control can be achieved by means of a paralyzing electric shock for example.

Since each portable electronic device 1 is capable of communicating data, in particular stimulation data, to another portable electronic device 1 either directly or via one or more intercalated portable electronic devices, it is possible to transmit 1310 stimulation, from at least one portable electronic device 1 at which an abnormality has been detected 1100, to portable electronic devices 1 located at most at a determined distance D from the portable electronic device at which an abnormality has been detected.

The distance D is as illustrated in FIG. 6 in which each "+" sign represents a portable electronic device and each sign "x" circled represents a portable electronic device at which an anomaly has been detected. This Figure 6 graphically illustrates that the number of portable electronic devices located at a distance D from a device at which an anomaly has been detected depends on the local density of the spatial distribution of the portable electronic devices. Thus, if the electronic device at which an anomaly has been detected and which is on the left of FIG. 6 solicits the generation 1320 of stimulations by a consequent set of devices thereby realizing an easily perceptible target in the center of which this device where an anomaly has been detected can be located.

In addition, users can be in motion, even in a crowd movement. In which case, a simple refreshing of the stimulation data communicated by the electronic device at which an anomaly has been detected, this refreshing being for example carried out by successive transmissions and at determined time intervals, for example as a function of an average speed estimated displacement of the users, makes it possible to no longer solicit the newly remote devices from a distance greater than the distance D and to request the newly located devices at a distance less than D. Thus, it is possible to locate a user in distress when this one is relatively motionless in the middle of a crowd movement. According to the same principle of refreshing, if the distressed user moves in conjunction with the crowd movement, a corresponding movement of the target formed around the distressed user can be perceived which makes it possible to permanently locate the user by distress.

It should be noted that there is advantageously no need to be able to individually locate each portable electronic device at the place of the event, for example by triangulation of Wi-Fi radio signals and / or Bluetooth and / or radio waves by the implementation of geolocation means GPS type, to allow according to the invention to detect and locate an anomaly. Indeed, the detection can be sound, visual or behavioral.

According to one embodiment, each portable electronic device is locatable by a GPS module belonging to the measurement modules, and / or by means of a triangulation from the relay antennas.

The present invention is not limited to the previously described embodiments and extends to all the embodiments covered by the claims.

For example, it is possible to combine the above described use that can be made of the invention with the use of existing security devices, such as for example a video surveillance device.
