Description

Detector and method for detecting neuronal signal frequency; Device and method for reproducing paginated content

[0001] The invention relates to a detector and a method for detecting neuronal signal frequency, and a device and a method for reproducing paginated content, in particular digital books. State of the art

[0002] E-readers, also known as "e-readers," offer users the advantage of reading digital books with optimal visual comfort. They are equipped with an electronic ink screen that reduces eye strain and provides an experience similar to reading printed books.

[0003] The main difference between reading on an e-reader and reading a printed book lies in turning pages. E-readers generally require manual interaction from the user to turn pages.

[0004] The most common approaches include the use of physical buttons implemented on the frame of the e-reader, specifically on an edge of the e-reader adjacent to the screen, or a gesture on a touch screen of the e-reader.

[0005] Repeated use of physical buttons generally leads to mechanical wear and tear, consequently reducing the lifespan of the e-reader. One solution to avoid this reduced lifespan due to wear and tear on physical buttons associated with page turning is to use a touchscreen.

[0006] While touchscreens are less prone to wear and tear from repeated page turns, touch interactions can sometimes be misinterpreted by the touchscreen, leading to errors in the e-reader's reproduction of the digital book, such as displaying the wrong page. This type of error can cause user frustration, or even lead to abandoning the e-reader and returning to printed books.

[0007] Furthermore, in certain situations where an e-reader is used to consult a paginated document, such as a book, due to circumstances related to a disability or daily activities (lunch, manual labor, etc.), manually turning pages can be difficult or even impossible. Indeed, a user with physical limitations, such as joint problems (painful, deformed, or stiff joints), tremors, or other fine motor impairments, may have difficulty pressing a button, especially a page-turn button on an e-reader, and / or performing a precise gesture on a touchscreen, particularly a gesture to trigger a page turn. In addition, a user may have their hands occupied at certain times (meals, work, etc.), which will hinder their ability to manipulate the e-reader to turn pages.

[0008] Therefore, current methods of changing pages on e-readers have limitations in terms of accessibility and, possibly, durability.

[0009] One of the aims of the present invention is to remedy some drawbacks of the prior art.

[0010] An object of the invention is a device for reproducing paginated content comprising: - a permanent visual neural stimulator at a given frequency, the given frequency being associated with a given command of the reproduction device, the permanent visual neural stimulator being positioned on the reproduction device according to the associated given command.

[0011] Thus, user interaction with content pages is a hands-free solution that improves the user experience. Therefore, such a reproduction device, particularly an e-reader, takes advantage of advances in brain-computer interface (BCI) technologies by integrating them.

[0012] Advantageously, the reproduction device includes: - a controller for reproducing paginated content capable of applying to the reproduced paginated content a given command associated with a frequency of a received neural signal.

[0013] Thus, the command is implemented quickly because the controller is implemented in the reproduction device itself.

[0014] Advantageously, the reproduction device includes: - a frequency detector in a neuronal signal, the frequency detector being able to: + identify a given frequency of a permanent visual neuronal stimulus reproduced by a visual neuronal stimulator, and + trigger a command associated with the detected frequency when the detected frequency corresponds to a given frequency.

[0015] Thus, the command is implemented quickly because the detector is implemented in the reproduction device itself.

[0016] Advantageously, the given frequency is a blinking frequency of a permanent visual neuronal stimulus reproduced by the visual neuronal stimulator.

[0017] Thus, the detector is robust, limiting detection errors and therefore reducing associated command errors. The user's document reading experience will then be smoother and faster.

[0018] Advantageously, the given command is a command to change pages of the reproduced paginated content.

[0019] A page change command is understood to mean any command relating to a page of the reproduced content, including: - a command to change a page from the page being reproduced, such as a command to reproduce the next page or the previous page of the page currently being reproduced, - a command to change a chapter (command to reproduce the first page of the previous chapter or the next chapter), - a command to reproduce the table of contents page, - a command to reproduce a page indicated in the page being reproduced (page indicated in the table of contents, in a footnote, in a reference, etc.), - etc.

[0020] Advantageously, the position of the permanent visual neural stimulator is a function of the reading direction of a page of the reproduced paginated content.

[0021] Thus, the command to turn to the next or previous page is triggered by the simple movement of the reader's eyes while reading the paginated content, when the stimulus enters their field of vision. This reduces eye strain for a user who would otherwise have to perform specific eye movements to trigger a so-called neural command—that is, a command triggered by a neural signal. Furthermore, this reduces the risk of user interaction errors with the paginated content, since it is a natural eye movement during reading that triggers the perception of the persistent visual neural stimulus, generating the neural signal that initiates the given command.

[0022] Advantageously, the permanent visual neural stimulator is one of the following: - a physical device; - a light-emitting diode; - a part of a screen corresponding to a peripheral display area of ​​a screen reproducing the paginated content in a central display area.

[0023] An object of the invention is also a frequency detector of a neuronal signal comprising: - a neuronal signal analyzer capable of identifying a given frequency of a permanent visual neuronal stimulus reproduced by a visual neuronal stimulator, the given frequency being associated with a given command of a device for reproducing paged content, the permanent visual neuronal stimulator being positioned on the reproduction device according to the associated given command.

[0024] Thus, the given command can be triggered hands-free, including in noisy environments or when reproducing confidential documents.

[0025] An object of the invention is further a method of reproducing paginated content implemented by a paginated content reproduction device, the reproduction method comprising: - reproducing a page of paginated content, and - triggering a reproduction of a permanent visual neural stimulus at a given frequency, the given frequency being associated with a given command of the reproduction device, the reproduction of the permanent visual neural stimulus being positioned on the reproduction device according to the associated given command.

[0026] Advantageously, the reproduction process includes: - controlling the reproduction of the paginated content according to a given command associated with a frequency of a received neuronal signal.

[0027] Advantageously, the reproduction process involves: - detecting a frequency of a neuronal signal, the frequency detection triggering control by a command associated with the detected frequency when the detected frequency corresponds to a given frequency.

[0028] Advantageously, frequency detection involves: - analyzing a neuronal signal, the analysis of the neuronal signal identifying a given frequency of a permanent visual neuronal stimulus reproduced by a visual neuronal stimulator, the given frequency being associated with a given command of a paged content reproduction device, the permanent visual neuronal stimulator being positioned on the reproduction device according to the associated given command.

[0029] An object of the invention is also a method for detecting frequency in a neuronal signal comprising: - analyzing a neuronal signal, the analysis of the neuronal signal identifying a given frequency of a permanent visual neuronal stimulus reproduced by a visual neuronal stimulator, the given frequency being associated with a given command of a device for reproducing paged content, the permanent visual neuronal stimulator being positioned on the reproduction device according to the associated given command.

[0030] Advantageously, the analysis identifies a given frequency in a neuronal signal when the amplitude of the neuronal signal is greater than a threshold amplitude.

[0031] Advantageously, according to one implementation of the invention, the various steps of the process according to the invention are implemented by a software or computer program, this software comprising software instructions intended to be executed by a data processor of a paged content reproduction device and / or a frequency detector and being designed to control the execution of the various steps of this process.

[0032] The invention therefore also relates to a program comprising program code instructions for the execution of the steps of the process of reproducing paginated content and / or of the process of frequency detection according to the invention when said program is executed by a processor.

[0033] This program can use any programming language and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form or in any other desirable form.

[0034] The features and advantages of the invention will become clearer upon reading the description, given by way of example, and the related figures which represent:

[0043] Laillustre a simplified diagram of a device for reproducing paginated content according to the invention.

[0044] The reproduction device 1 for paginated content c comprises: - a permanent visual neural stimulator 12, 12 i at a given frequency f, the given frequency f being associated with a given command cmd of the reproduction device 1, the permanent visual neural stimulator 12, 12 i being positioned pos, pos i on the reproduction device 1 according to the given associated command cmd.

[0045] Permanent means in particular that the stimulator emits the visual neuronal stimulus continuously as long as the reproduction device reproduces paged content.

[0046] The permanence of the visual neuronal stimulus contributes in particular to: - the simplicity of the reproduction device according to the invention; - a reasonable price of a reproduction device according to the invention; - the reduction of the risks of impossibility of interaction due to non-detection linked to the non-presence of the stimulus at an opportune time.

[0047] In particular, the reproduction device 1 includes: - a controller 14 for reproducing paged content c capable of applying to the reproduced paged content a given command cmd associated with a frequency fn of a neural signal sn.

[0048] In particular, the reproduction device 1 comprises: - a frequency detector 13 in a neuronal signal sn, the frequency detector 13 being capable of: + identifying a given frequency f of a permanent visual neuronal stimulus sv, sv(f) reproduced by a visual neuronal stimulator 12, 12 i, and+ to trigger a cmd command associated with the detected frequency fn when the detected frequency fn corresponds to a given frequency f: fn=f.

[0049] In particular, the given frequency f is a blinking frequency of a permanent visual neuronal stimulus sv reproduced by the visual neuronal stimulator 12, 12 i .

[0050] In particular, the given cmd command is a command to change pages of the reproduced paginated content.

[0051] A page change command is understood to mean any command relating to a page of the reproduced content, including: - a command to change a page from the page being reproduced, such as a command to reproduce the next page or the previous page of the page currently being reproduced, - a command to change a chapter (command to reproduce the first page of the previous chapter or the next chapter), - a command to reproduce the table of contents page, - a command to reproduce a page indicated in the page being reproduced (page indicated in the table of contents, in a footnote, in a reference, etc.), - etc.

[0052] In particular, the position pos, pos i of the visual neural stimulator 12, 12 i is a function of the reading direction rd of a page of the reproduced paginated content c(m). In the example of the, the position pos, pos i of the visual neural stimulator 12, 12 iis shown in Cartesian coordinates (abscissas x, x i and ordered y, y i ) : pos(x,y), pos i (x i ,y i ). This is a non-limiting example; the position pos can also be expressed in polar coordinates, particularly in the case of holographic displays.

[0053] In particular, the visual neural stimulator 12, 12 i is a stimulator among the following: - a physical device; - a light-emitting diode; - a part of a screen corresponding to a peripheral display area of ​​a screen reproducing the paginated content in a central display area.

[0054] In particular, the reproduction device 1 includes a page reproducor of the paginated content 15 capable of providing a display 17, in particular a screen, a holograph, etc., with a page of paginated content c(m) for the purpose of its reproduction by the display 17.

[0055] In particular, the reproducer 15 receives the content c from a storage device 16, 46. The storage device 16, 46 is in particular a content storage device, or even a paginated content storage device, such as a paginated content database.

[0056] In one embodiment, the reproduction device 1 includes a storage device 16.

[0057] In another alternative or complementary embodiment to the previous one, a content provider 4 includes a storage device 46. The reproduction device 1 is connected to the content provider 4 in particular via a remote or local communication network 5.

[0058] In particular, the storage device 16, 46 provides paged content c to the reproducer 15 on request for content c_rq from the reproducer 15.

[0059] Generally, the reproducer 15 provides the display 17 with the pages of the content to be reproduced successively, in particular from the first to the last: c(1)…c(m)…c(M), for a content c of M pages either automatically (for example, the reproducer provides the next page after the display time of a page has expired, which is a function of a reading speed and the number of words on the page), or on command from the user by means of a user interface.

[0060] In the reproduction device 1 described by the, the user interface enabling page change is a direct neural interface 2 connected to the reproduction device 1.

[0061] In particular, the visual neural stimulator 12, 12i is placed on the frame 11 of the screen 17 of the reproduction device 1. In the case of the example in the first part, the reading direction rd of the reproduced page c(m) on the screen 17 of the reproduction device 1 is from left to right and from top to bottom. Therefore, the visual neural stimulator 12, 12i, whose frequency f of the continuous visual neural stimulus sv(f) is associated with the command cmd for reproducing the next page, is positioned pos, pos i bottom right of frame 11.

[0062] Thus, reader U, reading page c(m) of content c on screen 17 of the playback device 1, will naturally have their gaze directed towards the visual neural stimulator 12, 12i at the end of reading this page c(m). They will then receive the continuous visual neural stimulus sv(f) whose frequency f is associated with the command to reproduce the next page cmd, cmd(m+1). Then the evoked potential of reader U's brain s eeg will naturally take the frequency f of the permanent visual neuronal stimulus sv(f). And, the direct neuronal interface will detect a neuronal signal sn whose frequency fn will be equal to the frequency f of the permanent visual neuronal stimulus sv(f).

[0063] In particular, the reproduction device 1 will receive from the direct neural interface 2 a neuronal feedback rn including in particular either the neuronal signal sn detected by the direct neural interface 2: rn=sn, or the neuronal frequency fn of the neuronal signal sn detected by the direct neural interface 2: rn=fn.

[0064] The reproduction device 1 and the direct neural interface 2 are connected either by wire or via a local communication network (not shown). In particular, the reproduction device 1 includes a receiver 10 capable of receiving the neural feedback rn transmitted by the neural interface 2, notably via the local communication network.

[0065] In a particular embodiment, when the reproduction device 1 receives the neuronal signal sn from the neuronal interface 2, in particular by means of the receiver 10, the frequency detector 13 is then able to detect in the neuronal signal sn the neuronal frequency fn and to provide the detected neuronal frequency fn to the controller 14.

[0066] In an alternative embodiment, when the reproduction device 1 receives the neuronal frequency fn from the neuronal interface 2, in particular by means of the receiver 10, it provides the received neuronal frequency fn to the controller 14.

[0067] In particular, controller 14 is capable of determining, based on the neuronal frequency fn, the command to be implemented. Specifically, controller 14 is capable of searching for the command cmd associated with a frequency f equal to the neuronal frequency fn. For example, controller 14 is capable of consulting a frequency storage device 140, such as a frequency database, in which the pairs of given frequency-associated given command corresponding to the visual neuronal stimulators of the reproduction device are stored. In particular, the reproduction device 1 includes the frequency storage device 140.

[0068] In particular, controller 14 is capable of ordering the reproduction of a specific page of the paginated content according to the command cmd, cmd(m+1) thus determined. For example, controller 14 orders the reproducer 15 with the command cmd, cmd(m+1) thus determined.

[0069] In this case, in the example above, the command `cmd`, `cmd(m+1)`, is a command to reproduce the next page. Therefore, the display 17 shows the next page of the reproduced content `c(m+1)`.

[0070] Laillustre a simplified diagram of a frequency detector in a neuronal signal according to the invention.

[0071] The frequency detector 3 of a neuronal signal sn comprises: - an analyzer 30 of a neuronal signal sn capable of identifying a given frequency f of a permanent visual neuronal stimulus sv(f) reproduced by a visual neuronal stimulator 12, 12i, the given frequency f being associated with a given command cmd of a paged content reproduction device 1, the visual neuronal stimulator 12, 12i being positioned pos, pos i on the reproduction device 1 according to the given associated command cmd.

[0072] In particular, a visual neural stimulator reproducing a permanent visual neural stimulus is also called a permanent visual neural stimulator.

[0073] In particular, a direct neural interface 2 carried by the user U of the reproduction device 1 provides the neural signal sn to the frequency detector 3.

[0074] In particular, the analyzer 30 determines the neuronal frequency fn of the neuronal signal sn of a user U of the reproduction device 1. The neuronal frequency fn thus determined corresponds to the given frequency f of the permanent visual neuronal stimulus sv(f) when the user U looks at the visual neuronal stimulator 12, 12i reproducing the permanent visual neuronal stimulus sv(f).

[0075] In particular, the analyzer 30 is capable of performing real-time analysis of the neural signal sn. This reduces the delay between the user's neural interaction U with the reproduced content and the execution of the associated given command.

[0076] In particular, the frequency detector 3 provides the neuronal frequency fn as a given frequency identified f to the reproduction device 1. Thus, the reproduction device 1 can implement the given command cmd associated with the given frequency f corresponding to the provided neuronal frequency fn when reproducing the paged content c.

[0077] In one particular embodiment, the frequency detector 13 is implemented in the reproduction device 1 (see). In an alternative embodiment, the frequency detector 23 is implemented in the direct neural interface 2 (see).

[0078] Laillustre a simplified diagram of a frequency detector in a neural signal implemented in a direct neural interface according to the invention.

[0079] The direct neural interface 2 is capable of providing a neuronal signal sn, notably as a function of a captured evoked potential s eeg of user U of the device for reproducing paginated content 1.

[0080] In particular, the direct neural interface 2 is suitable for being worn by the user U of the paged content reproduction device 1.

[0081] In particular, the direct neural interface 2 comprises one or more neural sensors 211, 212, …, 21 k Each neuronal sensor 211, 212, …, 21 k is capable of capturing an evoked potential from the user's brain. eeg Specifically, the neural sensor is capable of providing a captured signal sc1, sc2, …, sc k including the potential evoked captured eegIn other words, neural sensors capture neural signals in which one or more evoked potentials can be found. Specifically, several sensors can detect the same evoked potential (with varying degrees of difference depending on the distance between sensors).

[0082] In particular, sensors 211, 212, …, 21 k are optimally placed in the direct neural interface 2 to be optimally positioned relative to the brain of the user U wearing the direct neural interface 2 in order to detect evoked potentials (in particular they are positioned relative to the occipital area of ​​the brain).

[0083] In particular, the direct neural interface includes a neural signal detector 22. The neural signal detector 22 is capable of detecting a neural signal sn in particular as a function of a captured evoked potential.

[0084] In particular, the neuronal sensor 211, 212, …, 21 k is capable of providing the captured signal sc1, sc2, …, sc k to the neural signal detector 22. The neural signal detector 22 is then able to provide the neural signal sn as a function of the signals captured sc1, sc2, …, sc k .

[0085] In particular, the direct neural interface 2 is capable of providing the neural signal sn to the reproduction device 1. Thus, the reproduction device 1 is capable of controlling the reproduction of a specific page c(m j ) of the paginated content c as a function of the received neuronal signal sn.

[0086] In the example of the, the direct neural interface 2 includes, in particular, a frequency detector 23 of the neural signal sn. The frequency detector 23 is capable of identifying a given frequency f of a permanent visual neural stimulus sv(f) reproduced by a visual neural stimulator 12, 12i.

[0087] In particular, the frequency detector 23 comprises: - an analyzer 230 of a neuronal signal sn capable of identifying a given frequency f of a permanent visual neuronal stimulus sv(f) reproduced by a visual neuronal stimulator 12, the given frequency f being associated with a given command cmd of the paged content reproduction device 1, the visual neuronal stimulator 12 being positioned pos on the reproduction device 1 according to the given associated command cmd.

[0088] In particular, the analyzer 230 determines the neuronal frequency fn of the neuronal signal sn of a user U of the reproduction device 1. The neuronal frequency fn thus determined corresponds to the given frequency f of the permanent visual neuronal stimulus sv(f) when the user U looks at the visual neuronal stimulator 12, 12i reproducing the permanent visual neuronal stimulus sv(f).

[0089] In particular, the frequency detector 23 provides the neuronal frequency fn as a given frequency identified f to the reproduction device 1. Thus, the reproduction device 1 can implement the given command cmd associated with the given frequency f corresponding to the neuronal frequency provided fn when reproducing the paged content c.

[0090] In particular, the Direct Neural Interface 2 is implemented in a headset. Specifically, the Direct Neural Interface is an EEG headset. The headset used for the Direct Neural Interface 2 is particularly lightweight and comfortable. It is specifically designed to measure neural signals without interfering with the user's experience of viewing or reading the displayed content page.

[0091] Laillustre a diagram of the exchanges between the processes implemented by the invention, in particular the process of reproducing paginated content and the frequency detection process.

[0092] Laillustre a process for reproducing paginated content CR is implemented by a paginated content reproduction device DR. The reproduction process CR includes:- reproducing PG_RPR a page c(m) of a paginated content c, and- triggering ST_TRG a reproduction VNS of a permanent visual neuronal stimulus sv(f) at a given frequency f, the given frequency f being associated with a given command cmd of the reproduction device 1, the reproduction VNS of the permanent visual neuronal stimulus sv(f) being positioned pos on the reproduction device 1 according to the given associated command cmd.

[0093] In particular, the CR reproduction process includes: - controlling RCNT the reproduction of the paged content CR according to a given command cmd associated with a frequency fn of a received neuronal signal sn.

[0094] In particular, the CR reproduction process includes: detecting a frequency FDTCT of a neuronal signal sn, the detection of frequency FDTCT triggering the RCNT control by a command cmd associated with the detected frequency fn when the detected frequency fn corresponds to a given frequency f.

[0095] In particular, FDTCT frequency detection includes: analyzing SN_NZ a neuronal signal sn, the analysis of the neuronal signal SN_NZ identifying a given frequency f of a permanent visual neuronal stimulus sv(f) reproduced by a visual neuronal stimulator VST, the given frequency f being associated with a given command cmd of the DR reproduction device of paged content, the visual neuronal stimulator VST being positioned on the DR reproduction device according to the given associated command cmd.

[0096] Laillustre further illustrates a method for detecting FDTCT frequency in a neuronal signal sn.

[0097] This FDTCT frequency detection method is either implemented in an independent device, such as an FDT frequency detector not illustrated by the figure, or implemented by the CR reproduction method of paged content, or implemented by the IN neural interaction method.

[0098] The FDTCT frequency detection process detects the neuronal frequency fn of the neuronal signal sn captured by the direct neuronal interface IN.

[0099] The FDTCT frequency detection process includes: - analyzing SN_NZ a neuronal signal sn, the analysis of the neuronal signal SN_NZ identifying a given frequency f of a permanent visual neuronal stimulus sv(f) reproduced by a visual neuronal stimulator VST, the given frequency f being associated with a given command cmd of the DR reproduction device of paged content, the visual neuronal stimulator VST being positioned on the DR reproduction device according to the given associated command cmd.

[0100] In particular, SN_NZ analysis identifies a given frequency f in a neuronal signal sn when the amplitude of the neuronal signal sn is greater than a threshold amplitude (not shown).

[0101] As the field of vision moves towards the visual neural stimulator, for example the LED, the activation in the brain (i.e. the evoked potential) amplifies and it is possible to define a threshold from which the evoked potential will be detected.

[0102] Thus, if user U perceives the continuous visual neuronal stimulus sv(f) without looking at it, the amplitude of the neuronal signal sn whose neuronal frequency fn corresponds to the given frequency f of the stimulus sv(f) will be less than or equal to the threshold amplitude. Frequency detection will therefore not consider the neuronal frequency fn as detected and will not provide a detected frequency. Consequently, frequency detection FDTCT will not trigger any command through RCNT control.

[0103] However, if user U looks at the persistent visual neural stimulus sv(f), particularly because it is located directly after the end of the displayed text on the reproduced page c(m), the amplitude of the neural signal sn, whose neural frequency fn corresponds to the given frequency f of the stimulus sv(f), will be greater than the threshold amplitude. Frequency detection will then consider the neural frequency fn to be detected and will provide it as the detected frequency. Consequently, frequency detection FDTCT will trigger the given command cmd by the RCNT control, the given command cmd being the one associated with the given frequency f equal to the detected neural frequency fn.

[0104] Consider that the CR paginated content reproduction process implements the reproduction of paginated content c, specifically obtained OBT (not shown) from a BDC content database. The reproduced paginated content c is obtained OBT from the BDC content database following an RQ_EM submission of a c_rq content request, notably via the CR content reproduction process.

[0105] The CR paged content reproduction process then involves the reproduction PG_RPR of a page c(m) of the paged content c, generally starting with the first page m=1, and the triggering of permanent visual neural stimuli ST_TRG, particularly appropriate for the page being reproduced.

[0106] In particular, the CR paged content reproduction process involves a permanent stimulus triggering ST_TRG.

[0107] In particular, reproducing a PG_RPR page triggers the ST_TRG permanent stimulus. Optionally, the ST_TRG permanent stimulus trigger command includes an indication of the page being reproduced (specifically, the type of page: table of contents, any page, first chapter page, etc.). Thus, the ST_TRG permanent stimulus trigger will activate different permanent visual neural stimuli depending on the type of page being reproduced.

[0108] In particular, the CR paged content reproduction process includes one or more visual neural stimulations VNS, notably implemented by one or more visual neural stimulators VST.

[0109] In particular, the ST_TRG permanent stimulus triggers one or more visual neural stimulations (VNS), depending on the type of page being reproduced.

[0110] A user U views, or even reads, a reproduced paginated content c, in particular the reproduced page c(m) of the paginated content c.

[0111] In particular, when the permanent visual neural stimulus sv(f) is reproduced in a position placed at the end of the reading of the reproduced page c(m), the user U looks at the permanent visual neural stimulus sv(f) once the reading of the reproduced page c(m) of the content c is complete.

[0112] In this scenario, that is, when user U looks at the continuous visual neuronal stimulus sv(f), the continuous visual neuronal stimulus sv(f) of a given frequency f triggers an evoked potential s eeg in the brain of user U whose frequency is equal to the given frequency f of the permanent visual neuronal stimulus sv(f).

[0113] In particular, a direct neuronal interaction (IN) process implemented by a direct neuronal interface (BCI) is capable of determining a neuronal signal (sn) as a function of the evoked potential (s). eeg of the user's brain U.

[0114] In particular, the direct neuronal interaction (IN) process involves: - capturing a potential evoked by a CPT eeg of the user's brain U.

[0115] In particular, CPT capture provides a captured signal that is a function of the evoked potential. eeg of the user U's brain during CPT capture. Note that the frequency of the captured signal sc is equal to the given frequency of the permanent visual neuronal stimulus sv(f) when the user U looks at the permanent visual neuronal stimulus sv(f).

[0116] In particular, the direct neuronal interaction (IN) process involves neuronal detection using BDTCT. BDTCT detects a neuronal signal sn based on the evoked potential s eeg of the user's brain U during CPT capture, particularly as a function of the captured signal sc provided by the CPT capture. Note that the frequency of the neuronal signal sn is equal to the given frequency of the permanent visual neuronal stimulus sv(f) when the user U looks at the permanent visual neuronal stimulus sv(f).

[0117] In particular, the direct neuronal interaction process IN, notably neuronal detection BDTCT, provides the neuronal signal sn to the reproduction process CR.

[0118] Optionally, the direct neuronal interaction (IN) process includes frequency detection (FDCT). Thus, the IN process detects the neuronal frequency (fn) of the captured neuronal signal (sn), notably provided by neuronal detection (BDCT).

[0119] In particular, the IN direct neuronal interaction process, notably the FDTCT frequency detection of the IN direct neuronal interaction process, provides the frequency fn of the neuronal signal sn to the CR reproduction process.

[0120] In general, the direct neuronal interaction process IN provides neuronal feedback rn to the reproduction process CR, either the neuronal signal sn, or the frequency fn of the neuronal signal sn.

[0121] In particular, the CR reproduction process includes FDTCT frequency detection. Thus, the CR reproduction process detects the neuronal frequency fn of the neuronal signal sn provided by the direct neuronal interaction IN, notably through BDTCT neuronal detection.

[0122] In particular, the CR reproduction process includes RCNT control of reproduction as a function of neuronal frequency fn provided either by frequency detection FDTCT of the CR reproduction process, or by direct neuronal interaction IN (in particular by frequency detection FDTCT of the direct neuronal interaction process IN).

[0123] In particular, the RCNT command command directly reproduces a page of paginated content PG_RPR.

[0124] In particular, the RCNT control includes: - measuring the duration of the detected neuronal frequency DMST capable of determining the duration tn during which a neuronal frequency fn is detected.

[0125] In particular, the RCNT control includes: - checking tn>Tn if the measured duration tn of the detected neuronal frequency fn is long.

[0126] For example, if the measured duration tn is greater than a threshold duration Tn, it is considered long. The verification tn>Tn is performed specifically on the measured duration tn provided by the DMST duration measurement.

[0127] Thus, when user U glances quickly at the continuous visual neural stimulus sv(f), the duration tn of the corresponding neural frequency fn will be short, even instantaneous (for example, a few microseconds). And, when user U looks intently at the continuous visual neural stimulus sv(f), the duration tn of the corresponding neural frequency fn will be long (for example, a few seconds). Therefore, for a given frequency of a continuous visual neural stimulus sv(f), not one but two commands can be associated, depending on the duration tn of the detected neural frequency. For example, a short duration will be associated with a command to advance to the relevant page (next or previous), while a long duration will be associated with a command to advance to the first page of the relevant chapter (next or previous).

[0128] These associations of a given frequency, a given type of duration, and a given command will be pre-recorded in a frequency storage device, such as a frequency database (FDB). The association and recording of the association (not shown) are implemented during the manufacturing of the DR reproduction device, or even during the loading of the CR reproduction process into a DR reproduction device.

[0129] In particular, the RCNT control includes: - determining CMD_DT a cmd command based on the detected neuronal frequency fn.

[0130] In the absence of a duration measurement tn, the CMD_DT command determination provides a simple page change command: a command to reproduce a related page (previous or next page) , or an order to reproduce a given page , such as the summary page l=M for example, or page referenced in the reproduced page, etc.

[0131] In particular, the determination of the CMD_DT command is performed based on the duration type tn of the detected neuronal frequency fn, specifically provided by the tn>Tn check. For example, when the tn>Tn check indicates a long duration [Y], the determination of the CMD_DT command looks for the given command associated with the neuronal frequency for a long duration tn, for example, a chapter change command. When the tn>Tn check indicates a short duration [N], the CMD_DT command determination searches for the given command associated with the neuronal frequency for a short duration tn, for example, a related, neighboring page-changing command .

[0132] The RCNT control then commands the reproduction of page PG_RPR using the command cmd, which is a function of the neuronal frequency fn, notably provided by the determination of the command CMD_DT. The RCNT control commands cmd to reproduce page PG_RPR, the reproduction of a page paginated content other than that being reproduced c(m).

[0133] The new page The paginated content thus reproduced may be consulted, or even read, by the user U.

[0134] Furthermore, it will also be possible to add a time period (not shown) during which the displayed page cannot be changed, particularly by being turned inadvertently (for example, if one looks directly at the visual neural stimulator). This invariance period can be estimated from statistics on the consultation, or even reading, of the current content, or even of previously viewed content of the same type as the current content. This can be determined based on factors such as content type, font size, and user behavior. Once this invariance period has elapsed, the command associated with a detected neural frequency can be executed; for example, the page can be turned.

[0135] These processes are fast and transparent for the user, offering a smooth and uninterrupted browsing, or even reading, experience.

[0136] A particular embodiment of the paginated content reproduction process and / or the frequency detection process consists of a program comprising program code instructions for executing the steps of the paginated content reproduction process and / or the frequency detection process when said program is executed by a processor.

[0137] Figures 4a and 4b show simplified diagrams in which at least one visual neural stimulator is placed on the frame of a paged content reproduction device according to the invention.

[0138] The device for reproducing paginated content 1 includes, in particular, a display 17, such as a screen, and at least one visual neural stimulator 12 + 12 - 12 0, 12 1... 12 j Screen 17 is capable of displaying a page c(m) of paginated content c.

[0139] In the embodiment shown in Figures 4a and 4b, the paged content reproduction device 1 comprises a frame 11 surrounding the screen 17. The visual neural stimulators 12 + 12 - 12 0, 12 1... 12 j are arranged on this frame 11. Each visual neural stimulator 12 + 12 - 12 0, 12 1... 12 j emits a continuous visual neuronal stimulus of distinct frequencies sv(f + ), sv(f - ), sv(f0),sv(f 1),… , sv(fj).

[0140] In particular, visual neural stimulators 12 + 12 - 12 0, 12 1... 12 j are light-emitting diodes of distinct frequencies f + , f - , f0, f1,… , fj, aussi nommées LED. Notamment, la diode clignote à une fréquence fixe correspondant à la fréquence donnée f. Cette fréquence est par exemple de 12Hz, ou entre 1 et 60Hz (notamment lorsque plusieurs diodes sont utilisées). Dans un autre mode de réalisation, la diode clignote à une fréquence variable, par exemple une succession de fréquences, notamment constituant un code.

[0141] Using a given frequency of 12 Hz for a sustained visual neuronal stimulus, specifically the blinking of a light-emitting diode, allows for the generation of robust and easily detectable evoked potentials in EEG signals. This means that the neuronal frequency fn of the neuronal signal sn will be easier to detect and will correspond more accurately to the given frequency of the sustained visual neuronal stimulus when the user U is viewing it.

[0142] When the diode enters the peripheral vision of user U (particularly when reading the reproduced page of content), the blinking frequency generates a stationary visual evoked potential or SSVEP in the brain of user U. This evoked potential is detectable, in particular, by means of a direct neural interface, such as an EEG headset and, possibly, a frequency detection algorithm.

[0143] Laillustrates a first example of neural stimulators placed on the frame of a device for reproducing paginated content according to the invention.

[0144] In this first example, the reproduction device 1 has a reduced number of visual neural stimulators: only one 12 + (to go to the next page), or even two or a maximum of three (to return to the previous page 12 - , and / or access the summary of content 120).

[0145] The reproduced page c(m) has a reading direction rd from left to right and from top to bottom, also called the western reading direction.

[0146] According to the invention, the visual neural stimulator 12 + reproducing a permanent visual neuronal stimulus sv(f + ) whose given frequency f +is associated with a command to move to the next page cmd(m+1) is positioned on the bottom right corner of frame 11 so that the user U naturally looks at it at the end of reading the page c(m) reproduced on screen 17.

[0147] Thus, user U, finishing reading page c(m) reproduced with their gaze at the bottom right of screen 17, naturally looks at the permanent visual neural stimulus sv(f + ) emitted by the visual neural stimulator 12 + This generates a neuronal signal sn with neuronal frequency fn corresponding to the given frequency f + of this permanent visual neuronal stimulus sv(f + ). The reproduction device 1 then implements the given command cmd(m+1) associated with this given frequency and then reproduces the next page c(m+1) of the paginated content on the screen 17.

[0148] For another reading direction (not illustrated), for example Japanese: from top to bottom and right to left, the visual neural stimulator 12 + reproducing a permanent visual neuronal stimulus sv(f + ) whose given frequency f + is associated with a command to move to the next page cmd(m+1) will be positioned on the bottom left corner of frame 11 so that the user U naturally looks at it at the end of reading the page c(m) reproduced on screen 17.

[0149] In particular, the position of the visual neural stimulator 12 + on frame 11 is optimized so as not to distract the user U during the consultation, or even the reading, of the reproduced page c(m) but to be sufficiently visible at the end of the consultation, or even the reading, of this page.

[0150] According to the invention, the visual neural stimulator 12 - reproducing a permanent visual neuronal stimulus sv(f -) whose given frequency f - is associated with a command to return to the previous page cmd(m-1) is positioned on the top left corner of frame 11 so that the user U naturally looks at it when returning before the start of reading the page c(m) reproduced on screen 17 (for example, before the first word reproduced on this page).

[0151] Thus, user U, wishing to go back from reading page c(m) reproduced with their gaze at the top left of screen 17, naturally looks at the permanent visual neural stimulus sv(f - ) emitted by the visual neural stimulator 12 - This generates a neuronal signal sn with neuronal frequency fn corresponding to the given frequency f - of this permanent visual neuronal stimulus sv(f -). The reproduction device 1 then implements the given command cmd(m-1) associated with this given frequency and then reproduces the next page c(m-1) of the paginated content on the screen 17.

[0152] By convention, in order to avoid in particular the gaze of the user U when he is reading the reproduced page of the content c(m), the visual neural stimulator 120 reproducing a permanent visual neural stimulus sv(f0) whose given frequency f0 is associated with a command to go to the summary page cmd(M) is positioned away from the reading of the reproduced page c(m), for example at the bottom in the middle of the frame 11 so that the user U looks at it only when he wants to access the summary.

[0153] Thus, user U, wishing to access the table of contents of a page being reproduced, conventionally views the continuous visual neuronal stimulus sv(f0) emitted by the visual neuronal stimulator 120. This generates a neuronal signal sn with a neuronal frequency fn corresponding to the given frequency f0 of this continuous visual neuronal stimulus sv(f0). The reproduction device 1 then implements the given command cmd(M) associated with this given frequency and reproduces the table of contents page c(M) of the paginated content on the screen 17.

[0154] Laillustrate a second example of neural stimulators placed on the frame of a device for reproducing paginated content according to the invention.

[0155] In this second example, the reproduction device 1 includes a significant number of visual neural stimulators, notably: - those provided for in the, namely the visual neural stimulators 12 + (to go to the next page), 12 -(to return to the previous page), and / or 120 (access the table of contents); and possibly visual neural stimulators 12 1... 12 j planned in association with references, in this case reproduced on a summary page c(M).

[0156] In the second example illustrated by the diagram, the reproduced page c(M) is a summary of the paginated content c. It indicates a list of chapters ch1, ch2, …, chj and the first pages of each of these chapters m1, m2, …, m j And, visual neural stimulators 12 1... 12 j are associated with each of these chapters, more precisely the given frequencies f1,… , f j permanent visual neural stimuli sv(f1),… , sv(f j ) emitted by each of these visual neural stimulators 12 1... 12 j are respectively associated with given commands cmd(m1), cmd(m2), …, cmd(m j) corresponding to orders to reproduce the first pages of each of these chapters.

[0157] According to the invention, the visual neural stimulators 12 1... 12 j reproducing respectively a permanent visual neuronal stimulus sv(f1),… , sv(f j ) whose given frequency f1,… , f j is associated with a command cmd(m1), cmd(m2), …, cmd(m j ) reproduction of the first of chapter ch1, ch2, …, chj is positioned on the left of frame 11 opposite the reproduction of the mention of the chapter concerned on the reproduced summary page so that the user U looks at it naturally while continuing to read the line of the summary associated with the chapter of interest to him reproduced on screen 17.

[0158] Thus, user U, wishing to access chapter chj, continues reading the corresponding line and naturally looks at the permanent visual neuronal stimulus sv(f j) emitted by the visual neural stimulator 12 j positioned on the frame at the end of this line. This generates a neuronal signal sn of neuronal frequency fn corresponding to the given frequency f j of this permanent visual neuronal stimulus sv(f j ). The reproduction device 1 then implements the given command cmd(m j ) associated with this given frequency and then reproduces the first page c(mj) of chapter chj of the paginated content on screen 17.

[0159] Figures 5a and 5b show simplified diagrams in which at least one visual neural stimulator is reproduced directly by the display of a paged content reproduction device according to the invention.

[0160] The device for reproducing paginated content 1 includes, in particular, a display 17, such as a screen. The screen 17 constitutes, in at least one area thereof, a visual neural stimulator 172 + 172 - 1720, 172 1... 172 j Screen 17 is capable of displaying a page c(m) of paginated content c.

[0161] Thus, screen 17 emits at least one permanent visual neural stimulus of distinct frequencies sv(f + ), sv(f - ), sv(f0),sv(f 1),… , sv(fj) dans une zone de l’écran dédiée correspondant à un stimulateur neuronal visuel 172+, 172-, 1720,1721...172j

[0162] The advantage of using an area of ​​the screen as a visual neural stimulator is the ability to adapt the number of visual neural stimulators to the reproduced page of paginated content and / or the position of this / these visual neural stimulator(s) to the reproduced page of paginated content.

[0163] Laillustre a first example of neural stimulators reproduced by the screen of a device for reproducing paginated content according to the invention.

[0164] In this first example, since the page reproduced on screen 17 of the reproduction device 1 is any page, screen 17 displays a reduced number of visual neural stimulators: only one 172 + (to go to the next page), or even two or a maximum of three (to return to the previous page 172 - , and / or access the summary of content 1720).

[0165] The reproduced page c(m) has a reading direction rd from left to right and from top to bottom.

[0166] According to the invention, the area of ​​the screen 17 consisting of a visual neural stimulator 172 + reproducing a permanent visual neuronal stimulus sv(f + ) whose given frequency f + is associated with a command to move to the next page cmd(m+1) is positioned in the bottom right corner of screen 17 so that the user U naturally looks at it at the end of reading the page c(m) reproduced on screen 17.

[0167] Thus, user U, finishing reading page c(m) reproduced with their gaze at the bottom right of screen 17, naturally looks at the permanent visual neural stimulus sv(f + ) emitted by the visual neural stimulator 172 + This generates a neuronal signal sn with neuronal frequency fn corresponding to the given frequency f + of this permanent visual neuronal stimulus sv(f + ). The reproduction device 1 then implements the given command cmd(m+1) associated with this given frequency and then reproduces the next page c(m+1) of the paginated content on the screen 17.

[0168] According to the invention, the area of ​​the screen 17 consisting of a visual neural stimulator 172 - reproducing a permanent visual neuronal stimulus sv(f - ) whose given frequency f -is associated with a back to previous page command cmd(m-1) is positioned in the top left corner of screen 17 so that the user U naturally looks at it when returning before the start of reading the page c(m) reproduced on screen 17, i.e. naturally looks at the visual neural stimulator and therefore the permanent visual neural stimulus that it reproduces.

[0169] Thus, user U, wishing to go back from reading page c(m) reproduced with their gaze at the top left of screen 17, naturally looks at the permanent visual neural stimulus sv(f - ) emitted by the visual neural stimulator 172 - This generates a neuronal signal sn with neuronal frequency fn corresponding to the given frequency f - of this permanent visual neuronal stimulus sv(f -). The reproduction device 1 then implements the given command cmd(m-1) associated with this given frequency and then reproduces the next page c(m-1) of the paginated content on the screen 17.

[0170] By convention, in order to avoid in particular the gaze of the user U when he is reading the reproduced page of the content c(m), the area of ​​the screen 17 consisting of a visual neural stimulator 120 reproducing a permanent visual neural stimulus sv(f0) whose given frequency f0 is associated with a command to go to the summary page cmd(M) is positioned away from the reading of the reproduced page c(m), for example at the bottom in the middle of the screen 17 so that the user U looks at it only when he wants to access the summary, that is to say he looks at this visual neural stimulator and therefore at this permanent visual neural stimulus which it reproduces only when he wants to access the summary.

[0171] Thus, user U, wishing to access the table of contents of a page being reproduced, conventionally views the continuous visual neuronal stimulus sv(f0) emitted by the visual neuronal stimulator 1720. This generates a neuronal signal sn with a neuronal frequency fn corresponding to the given frequency f0 of this continuous visual neuronal stimulus sv(f0). The reproduction device 1 then implements the given command cmd(M) associated with this given frequency and reproduces the table of contents page c(M) of the paginated content on the screen 17.

[0172] Laillustre a second example of neural stimulators reproduced by the screen of a device for reproducing paginated content according to the invention.

[0173] In this second example, the reproduction device 1 includes a significant number of visual neural stimulators, notably: - those provided for in the, namely the visual neural stimulators 172 + (to go to the next page), 172- (to return to the previous page), and / or 1720 (access the table of contents); and possibly visual neural stimulators 172 1... 172 j planned in association with references, in this case reproduced on a summary page c(M).

[0174] In the second example illustrated by the diagram, the reproduced page c(M) is a summary of the paginated content c. It indicates a list of chapters ch1, ch2, …, chj and the first pages of each of these chapters m1, m2, …, m j And, areas of screen 17 consisting of visual neural stimulators 172 1... 172 j are associated with each of these chapters, more precisely the given frequencies f1,… , f j permanent visual neural stimuli sv(f1),… , sv(f j ) emitted by each of these visual neural stimulators 12 1... 12 j are respectively associated with given commands cmd(m1), cmd(m2), …, cmd(m j) corresponding to orders to reproduce the first pages of each of these chapters.

[0175] According to the invention, the visual neural stimulators 172 1... 172 j reproducing respectively a permanent visual neuronal stimulus sv(f1),… , sv(f j ) whose given frequency f1,… , f j is associated with a command cmd(m1), cmd(m2), …, cmd(m j ) reproduction of the first of chapter ch1, ch2, …, chj is positioned on the left of screen 17 opposite the reproduction of the mention of the chapter concerned on the reproduced summary page so that the user U looks at it naturally while continuing to read the line of the summary associated with the chapter of interest to him reproduced on screen 17.

[0176] Thus, user U, wishing to access chapter chj, continues reading the corresponding line and naturally looks at the permanent visual neuronal stimulus sv(f j) emitted by the visual neural stimulator 172 j positioned in the right part of the screen 17 at the end of this line. This generates a neuronal signal sn of neuronal frequency fn corresponding to the given frequency f j of this permanent visual neuronal stimulus sv(f j ). The reproduction device 1 then implements the given command cmd(m j ) associated with this given frequency and then reproduces the first page c(mj) of chapter chj of the paginated content on screen 17.

[0177] Neural interaction with a paginated content reproduction device allows for completely hands-free page changes, ideal for users with physical limitations, occasional constraints (meals, manual work – cooking, workshop, etc.) or those wishing for an uninterrupted experience.

[0178] The device for reproducing paginated content includes, in particular, an e-reader, but also any device that allows the reproduction of such content, such as tablets, smartphones, computer screens…

[0179] The invention also relates to a storage medium. The information storage medium can be any entity or device capable of storing the program. For example, the medium can include a storage means, such as a ROM, for example a CD-ROM or a microelectronic circuit ROM, or a magnetic recording means, for example a floppy disk or a hard disk drive.

[0180] On the other hand, the information medium can be a transmissible medium such as an electrical or optical signal that can be transmitted via an electrical or optical cable, by radio, or by other means. The program according to the invention can, in particular, be downloaded onto a network, notably the Internet.

[0181] Alternatively, the information carrier may be an integrated circuit in which the program is incorporated, the circuit being adapted to execute or to be used in the execution of the process in question.

[0182] In another implementation, the invention is implemented using software and / or hardware components. In this context, the term "module" can refer to either a software component or a hardware component. A software component corresponds to one or more computer programs, one or more subroutines of a program, or more generally, any element of a program or software capable of implementing a function or set of functions as described above. A hardware component corresponds to any element of a hardware assembly capable of implementing a function or set of functions.
