    [0001] Method of counting steps performed by a user. The present invention relates to step counting methods performed by a user. More particularly, the invention relates to a step counting method performed by a user, in parallel with a personal activity monitor and the step counting function of a smartphone, which can be connected together, to overcome a possible absence of counting of the personal activity monitor. Conventional activity monitors, as described in document US20130325399, are known which proceed to count the steps of a user. On the other hand, if the activity monitor for example is forgotten or if it fails (for example, no batteries), the user loses track of his activity and counts down the number of steps he has taken. made. It has therefore appeared the need to propose a method of parallel and complementary counting, by means of a connected apparatus, via a wireless link (for example by BluetoothTM), to said activity monitor. In US20130325399, the portable activity monitor is combined with a remote device to geolocate the collection of user activity information, but this association between a portable activity monitor and a remote device does not make it possible to overcome a lack of counting of the monitor. For this purpose, the invention proposes a step counting method performed by a user, said method being implemented firstly by a first portable electronic device formed by a personal activity monitor intended to be jointly associated with it. to the body of the user, and secondly, by a second portable electronic device formed by a smartphone, the first and second devices being configured to exchange data over a wireless link, the method comprising the steps: / al / detecting and counting the steps of the user by the first apparatus (1), with at least one associated timestamp information, / a2 / detecting and counting the steps of the user by the second apparatus (2), with at least associated timestamp information, / b / transferring step data from one of the two apparatuses to the other of the two apparatuses, / c / identifying at least a first period of time (Tw) for which that a difference in number of steps counted between the first and the second apparatus is greater than a predetermined threshold (S), / d / completing the step data recorded for said first period of time in one of the two apparatuses by the step data of the other of the two devices. Thanks to these arrangements, the step count data of one of the two devices can be supplemented or corrected by the data collected by the other of the two devices. In addition, the method has a symmetry vis-à-vis the two devices and can work regardless of the device that only partially counted the steps, or even failed to count. In preferred embodiments of the invention, one or more of the following arrangements may also be used. In step / al / or / a2 / one of the two devices did not count steps during said first period of time. Thus the method makes it possible to compensate for the fact that one of the two devices is forgotten by the user, or that his battery is in an unloaded state. During said first period of time (Tw), the pitch data was recorded by the second apparatus and not by the first apparatus, and in step / d / the data of the first apparatus is completed by the recorded step data. for said first period of time (Tw) in the second apparatus. The method can thus overcome the fact that the user can omit to carry or carry on his personal activity monitor. In step / b / the step counting data recorded by the first apparatus (1) is sent (21) to the second apparatus (2), and in step / c / 15 the identification of the first period time (Tw) is achieved by the second apparatus. Thus, the comparison calculations are made by the Smartphone which has more resources, and the activity monitor does not need to receive and evaluate the data collected by the Smartphone. In step / d /, the step data recorded by the second apparatus for said first period of time is transferred (22) to the first apparatus; so that the first apparatus can receive step count data that it has failed to count; in particular, the cumulative number of steps may include steps not initially counted by the first device but counted as redundancy (substitution) by the second device. The method may further include a step of synchronizing the clocks of the first and second apparatuses. As a result, the timestamp of the data collected by the two devices remains consistent and allows the devices to refer to a common time base. A time base comprising a plurality of successive time intervals is defined and in step / c /, the number of steps counted respectively by each of the two devices is compared during each of the successive intervals. So that we can see very simply and very quickly a counting inconsistency between the two devices. The second device contains a "step counting" application, configured to be activated selectively, by the observation of the absence of the first device in the vicinity of the second device, either that the first device is actually absent or that its battery is at a minimum. low or discharged level. So that the Smartphone comes replace the absence (or lack of charge) of the activity monitor only when necessary, which limits the power consumption.
    [0002] Activation of said application can be automatic. With which, the relaying by the Smartphone is completely transparent to the user, who has nothing to do in particular even if he has forgotten his personal activity monitor, the recovery of missing data will be automatic at the return of the connection of the two devices. The application in question is put on standby or deactivated by detecting the presence of the first device near the second device. With this, we optimize the power consumption on the Smartphone side, when the personal activity monitor is active. The predetermined threshold (S) is defined with respect to the difference between the number of steps (Nbl) counted by the first apparatus and the number of steps (Nb2) counted by the second apparatus, normalized by the greater of the two step numbers. , the value of the threshold then being preferably between 0.1 and 0.2. By means of this, the decision criterion is advantageously based on a dimensionless coefficient, a ratio independent of the duration of the time interval (T ', 1, Tw). The invention also relates to an information system for a user, comprising a first portable electronic device formed by a personal activity monitor intended to be integrally associated with the user's body, and a second portable electronic device formed by a smartphone, the first and second devices being configured to exchange data over a wireless link, each of the first and second devices being configured to detect and count the steps of the user, with at least one time stamping information, the system being configured to (/ b /) transfer step data from one of the two devices to the other of the two devices, to (/ c /) identify at least a first period of time (T ', i) for which is determined that a difference in number of steps counted between the first (1) and the second apparatus (2) is greater than a predetermined threshold (S), and for (/ d /) complete the donations steps recorded for said first period of time in one of the two apparatuses by the step data of the other of the two apparatuses. Advantageously, such an information system can implement one or the other of the arrangements that have been described above in connection with the method.
    [0003] Other features and advantages of the invention will become apparent from the following description of one of its embodiments, given by way of non-limiting example, with reference to the accompanying drawings.
    [0004] In the drawings: Figs. 1a and 1b show a user carrying an activity monitor and a smartphone; Fig. 2 illustrates the activity monitor; Fig. 3 shows a block diagram of the system formed by the monitor. FIG. 4 represents a timing diagram illustrating the operation of the invention in a first embodiment; FIGS. 5 to 7 illustrate timing diagrams similar to that of FIG. 4 for different scenarios; . In the different figures, the same references designate identical or similar elements. In Figs. 1a-1b, a user carries a first portable electronic apparatus 1 formed by a personal activity monitor associated integrally with the body of the user. The user also wears a second portable electronic device 2 formed here by a smartphone. Said second portable electronic device 2 may for example be located in the handbag that the user wears with him as illustrated in Figure 1, or in a garment bag, in a backpack or the like. Both devices 1.2 are provided to be able to connect together and exchange data, preferably over a wireless link. The wireless link can be formed by a BluetoothTM interface, WiFi, Zigbee, RFID or any other equivalent. Advantageously, in the case of a BluetoothTM link, the latter makes it possible to evaluate the distance between the two devices, by determining the power of the signals and the known propagation characteristics. In particular, the step data collected by one of the two apparatuses may be advantageously combined with the step data collected by the other apparatus. For example, the pitch data collected by the first apparatus 1 may be combined with the pitch data collected by the second apparatus 2, or vice versa.
    [0005] In the example illustrated in FIG. 2, the first portable electronic device 1 takes the form of an activity monitor, for example the "Pulse" TM product of the applicant. The activity monitor can be in the form of a small box, including a display system, which displays the activity. The activity monitor is able to inform the user about his physical activity, walking, running, sleep, climbing steps, etc.
    [0006] The first electronic device 1 can also take the form of another device incorporating an activity monitor, such as a "Smartwatch" TM watch, eyeglasses, or glasses type "Google glasses" TN, a headset, a hearing aid, an instrumented collar. As illustrated, the first electronic device 1 is adapted to be held substantially integral with at least a part of the body of said user during the realization of said method, for example worn on the belt of the user (see Figure la), or on a wrist strap attached to the user's wrist (see figure lb). It can be further integrated in a user-worn device, in an atrium, in a hearing aid. The second portable electronic device 2 takes the form of a smart telephone device, also called a smartphone, with a "step counting" application 25. The "step counting" application 25 may be a basic feature included in the lower layers from the operating system (such as AndroidlM or 30 iOSTM), or can be a feature included in a higher-level application accessible by the user. The second device 2 can also take the form of a tablet, phablette, a mini PC or an electronic organizer. As illustrated in FIG. 3, said first apparatus 1 comprises a calculation unit 14. A multi-axis acceleration sensor 7 connected to the calculation unit 14 makes it possible to detect accelerations experienced by the device, from which it is estimated that accelerations experienced by the user. The acceleration information may be used to estimate the number of steps taken by the user (step / al / of the method).
    [0007] The first apparatus 1 comprises a display 3 (also called display) configured to make available to the user a plurality of information including a step counter performed. The reset of this counter can be daily or other according to the configuration given by the user. The calculation unit 14 controls the display 3. It also communicates via a BluetoothTM communication interface 42. The calculation unit 14 processes the data via a processor which comprises a memory zone 47 and which manages the directly measured data therein. by the first device 1 or for example received from another device such as the second electronic device 2. The computing unit 14 also communicates with Bluetooth 25 to send data collected by the first device 1 for example to the second device 2 The computing unit 14 is powered by an on-board power source 8, here for example a rechargeable battery. This battery supplies all the elements 30 embedded in the device, namely the sensor 7, the display 3 and the calculation unit 14. As also illustrated in FIG. 3, said second apparatus 2 also comprises a computing unit 140.
    [0008] Said second apparatus 2 may for example comprise a multi-axis acceleration sensor 70 connected to the computing unit 140 making it possible to detect accelerations experienced by the device, from which it is estimated that the accelerations experienced by the user. The acceleration information may be used to estimate the number of steps taken by the user via the above-mentioned "step counting" application (step / a2 / of the method). Said second apparatus 2 may also include a GPS location function with a GPS receiver 10. Said second apparatus 2 may comprise a number of other applications that can be initiated by the user or run continuously in the background. The computing unit 140 comprises a display 30 that configures 15 to make available to the user a plurality of information, and in particular a counter of the steps taken. The reset of this counter can be daily or other according to the configuration given by the user. The computing unit 140 controls the display 30. The computing unit 140 also communicates via a BluetoothTM communication interface 420. The computing unit 140 processes the data via a processor which includes a memory area 470 and which integrates the data directly picked up by the "step counting" application 25 of the second device 2 or the data received in Bluetooth from another device such as the first device 1. The second device 2 also communicates in Bluetooth for transmitting and receiving data, for example with the first apparatus 1. The computing unit 140 is powered by an on-board power source 80, here for example a rechargeable battery. This battery supplies all the elements embedded in the device, namely the sensor 70, the display 30 and the calculation unit 140. The first device 1 and the second device 2 preferably have synchronized clocks. The clock synchronization is for example imposed by the second device 2, which transmits the time setting information to the first device 1. This clock synchronization can be redone once a day, for example. For example, both devices can synchronize their clocks at each Bluetooth handshake or periodically with a certain frequency. In general, the user carries the first device 1 and the second device 2. However, one of the two devices can be forgotten or unloaded, or the user prefers to wear one of the two devices depending on the type of device. practiced activity. When the two devices are again placed in Bluetooth communication (physically close together for example), advantageously according to the invention, the two devices synchronize their data.
    [0009] As known per se, the first device 1 regularly sends to the second device 2 the number of steps of the user for statistical purposes and display for the user on the display 30. This 'upload' of data (answers 21 , named step / b / process) can be done at each new Bluetooth connection, or according to a time slot logic, for example every five minutes, or even more frequently. Advantageously according to the invention, it will take advantage of the step counting capacity of the two devices, to identify that one of the devices did not count the steps, or made an incorrect count of the number of steps during one or several periods of time. More specifically, with reference to FIGS. 4-7, thanks to the synchronization of the clocks, a time scale is defined that is common to the two apparatuses, which forms a division into Tseq intervals. For each of said intervals (T ', i), the data detected and collected by each of the first and second devices are compared. If one of the two devices determines during said interval 'Ise, / a number of steps "much less" than the number of steps detected during the same interval T', / by the other device, the number of steps "much lower" may be zero or not zero but significantly less than the number of steps detected by the other device, the data of the number of steps for the interval 'Ise, / "much lower" will be said to be erroneous and will be the subject of a correction .
    [0010] We denote by Nbl the number of steps counted by the first device 1 and we write Nb2 the number of steps counted by the second device 2. Delta is denoted by the absolute value of the difference Nbl-Nb2, ie Delta = Nb1-Nb21. Advantageously, this difference will be compared directly or indirectly with a predetermined threshold (step / c / of the method). For example, the smallest of the values will be declared erroneous if the Delta difference is greater than a fixed threshold. Advantageously, a dimensionless number representative of the normalized deviation relative to the largest value nb1, Nb2 is defined as follows: Nb2V _: 1 - DeltaN is therefore the difference between the number of steps 30 (noted Nbl) counted by the first apparatus 1 and the number of steps (noted Nb2) counted by the second apparatus 2, normalized by the greater of the two numbers of steps.
    [0011] Advantageously, DeltaN is compared with a predetermined threshold (S). It will be possible to choose as the predetermined decision threshold S a value of between 0.1 and 0.2 for example.
    [0012] If DeltaN> S then the difference is significant and a correction is made, otherwise if DeltaN <S, the difference is not significant and does not lead to correction (this makes it possible to tolerate a certain difference in counting, without making repeated corrections not essential). The period of time during which one of the two apparatuses counted while the other apparatus did not count or carried out an erroneous count of the number of steps may comprise several consecutive Tseci intervals.
    [0013] In the figures, said period is bounded by times T100 and T200 and will be called 'first period of time' Tw. An interval T ', / will have for example a duration between 15s and 300s, preferably between 30s and 120s, typically 60s. Figures 4 to 7 illustrate the case where the Tseci period has a duration of 30s. If at the time of synchronization of data between the first device 1 and the second device 2, a time period of one or more intervals Tseci is identified without data collected by one of the two devices, the data of the device counted in this time period, will be used to be fed back (process step / d /) into the device data that did not count during this time. This makes it possible to correct the missing or erroneous count of one of the two devices (typically forgotten by the user). According to an embodiment illustrated in FIG. 4, if the user leaves without having equipped himself with his activity monitor 1, the user carries with him only the second portable electronic device 2. Said second device 2 can then count the steps of the user via the "counting step" application 25 of the second portable electronic device 2.
    [0014] For example, when the second device 2 moves away from the first device 1, the application (or task) "counting steps" 25 of the second device 2 is automatically launched by the observation of the absence of the first device 1 nearby the second device 2 (we can say that the Smartphone 'takes over' the activity monitor at the loss of the Bluetooth link), at the time Tno. Similarly, the "step counting" application 25 is put on standby or deactivated by detecting the presence of the first device 1 near the second device 2. More specifically, the "counting steps" application is for example interrupted when the first device 1 starts to count the detected steps and is in communication with the second device 2, at the moment Tuo. When the two devices are placed in BluetoothTM communication again, the two devices synchronize their data (reference 210), in particular the activity monitor performs an "upload" of the step counting data. The second apparatus 2 then compares the pitch data collected by the first apparatus 1 with those collected by the second apparatus 2 over the previous time intervals. The second apparatus 2 thus identifies, a posteriori, a period of time Tw, between the times Tuo and T200, of one or more intervals Tseci during which the application "counting step" 25 of the second apparatus 2 has detected data. steps, not detected by the first apparatus 1. For example for the first interval T ,,,,, after T100, Nb1 = 0 and Nb2 = 27; for the second interval, Nb1 = 0 and Nb2 = 33; for the third interval Nb1 = 0 and Nb2 = 28 and for the fourth interval Nb1 = 0 and Nb2 = 16, therefore DeltaN = 1 for each of the four aforementioned intervals, a value greater than the predetermined threshold S which consequently triggers a correction of data . In this case, the arrow marked 22 illustrates the step of reinjecting the data counted by the Smartphone 2 to the activity monitor 1, which can therefore update its data, in particular the daily accumulation of the number of steps. More generally, it is for example during the transfer of data from one device to the other, that the device dedicated to this task identifies the period of time Tw between the times T100 and T200 for which step data has actually been recorded by one of the two devices and not by the other. As a variant illustrated in FIG. 5, the application 20 "counting steps" 25 of the second apparatus 2 operates continuously in the background with its own means. In addition, the second apparatus 2 continuously collects the step data made by the activity monitor 1 (regular uploads 21), and can compare these data with the count data which it has itself recorded by its application. "Step count" clean. Alternatively the application "step counting" 25 can be started manually by the user when he realizes that he has forgotten the first device 1 30 (conventional pedometer application). In this embodiment, the second apparatus 2 detects and counts the steps of the user, for each interval Tseci of the time scale common between the first apparatus 1 and the second apparatus 2.
    [0015] In a variant illustrated in FIG. 6, the situation opposite to FIG. 4 is considered, that is to say that the second apparatus 2 has been forgotten at home or the batteries of the second apparatus 2 are out of order or too weak. In this variant, the first device 1 detects and counts the steps of the user for each interval T ,,,,, of the common time scale between the first device 1 and the second device 2.
    [0016] When both devices are in Bluetooth communication, both devices synchronize their data. The first device 1 transfers its data to the second device 2, for example defective, for example without batteries for a period Tw.
    [0017] The second device 2 can later make a comparison of the pitch data collected by the first device 1 with those collected by the second device 2. The second device 2 identifies a time period between the times TH0 and TH0 of one or more intervals Tseci during which the first device 1 has detected step data, not detected by the application "step counting" 25 of the second device 2. The second device 2 can thus complete the data in its own application of step counting (step / d / of the process). As a variant illustrated in FIG. 7, the user is provided with the two devices 1, 2, but one of the two devices is faulty, either because he has no more batteries or because he is counting wrong. This is the case, for example, if the apparatus is brought to an inappropriate place for counting steps. The other apparatus then counts and the invention operates as described above.
    [0018] For example the first device 1 is in the handbag of the user, and may have therefore made a wrong count. The data collected by the first device 1 is compared with the data collected by the second device 2. If there is a difference in the number of steps normalized by the highest datum higher than the predetermined threshold (S), over a period of At least one interval Tseqr the counting performed by the first device 1 is considered to be erroneous over this period of time between the times T100 and T200. For example, if the difference normalized by the highest datum is greater than the predetermined threshold (S) of 0.1, the number of steps counted by the first apparatus 1 during said period is considered to be erroneous.
    [0019] In this case as illustrated for the first interval T ,,,,, after Tuo, Nb1 = 5 and Nb2 = 27; for the second interval, Nb1 = 8 and Nb2 = 33; for the third interval Nb1 = 14 and Nb2 = 28 (DeltaN = 0.5) and for the fourth interval Nb1 = 6 and Nb2 = 16 (DeltaN = 0.625), therefore DeltaN> S for each of the four abovementioned intervals. The data of the second apparatus 2 in this period of time, will be used to be reinjected (22) in the data of the first device 1, to complete the data of the first device 1, including display a realistic plurality for the user. Alternatively (not shown in the figures), it should be noted that the data collected by the second device 2 could be sent to the first device 1 and the first device 1 would itself identify the period of time during which the application "counting of No. 25 of the second apparatus 2 has detected step data, undetected or poorly detected by the first apparatus 1. It should be noted that in general, one of the 35 devices may in the case of a piece of collected data simultaneously by the first device 1 and the second device 2, compare the data and judge the reliability of the data collected by one and the other of the devices. Advantageously, the physical proximity between the first apparatus 1 and the second apparatus 2 can stop or put into operation the operation of the "step counting" application 25 of the second apparatus 2. In this case, the second apparatus 2 is exclusively used for the transfer of data collected by the first apparatus 1 for processing. An additional display can be done on the second device 2 and / or the configuration management by an application of the second device 2 linked to the first device 1.
    [0020] It should be noted that when the first electronic apparatus 1 and the second electronic apparatus 2 are shipped by the user, the first electronic apparatus 1 is used in priority on the second electronic apparatus 2 for monitoring the activity of the user. . Indeed, the activity monitor is a device dedicated to the counting of steps and has greater accuracy in general than the Smartphone step counting application. The activity monitor 1 illustrated here weighs less than 10 grams, preferably less than 8 grams. Its dimensions are particularly small, the thickness being at most equal to 8 mm, the width at most equal to 43 mm, the height at most equal to 22 mm, it is particularly discreet to wear.
    [0021] It should also be noted that the user could wear more than one device having the role of an activity monitor, for example two or three devices, for example a hearing aid, glasses of the "Google glasses" TM type, and an instrumented bracelet. In this case, the comparison method described above may relate to the comparison of all the data made available by the plurality of apparatuses acting as an activity monitor, for example three sets of step data respectively collected. by each device and transmitted to the Smartphone. Said smartphone can then identify data to be corrected and can reinject the missing data in any of the devices acting as activity monitor.
