Description

Technical field

[0001] The present invention relates to a method for broadcasting by a watch an informative message relating to an evaluation of the quality of life of a wearer of said watch and a system implementing such a method.

[0002] The invention also relates to a watch comprising such a system as well as a computer program. Prior art

[0003] The variation in an individual's quality of life has an impact on different states of the latter such as the physical state, the psychological state or even the somatic state. In such a context, we understand then that it is important to be able to evaluate this quality of life of an individual in order to be able to improve it if necessary.

[0004] To do this, we know in the state of the art methods providing for carrying out an evaluation of the quality of life by implementing a processing of measurement data generally coming from activity monitoring sensors or physiological sensors.

[0005] Also known in the state of the art is document WO2007 / 107900A2, which describes a method for displaying a degree of relaxation of a wearer of a watch, as well as document US2016 / 246259A1, which relates to a method for automatically reminding a user to sleep. Also known is document WO2011109716A2, which describes a method for permanently monitoring one or more physiological parameters of a subject.

[0006] However, one of the major drawbacks of such processes is linked to the fact that the proposed quality of life assessment is often imprecise or even erroneous due to the fact that it is carried out using measurement data that is sometimes difficult to obtain and which is not always directly linked to conditions related to quality of life.

[0007] It is understood that there is a need to find an alternative solution, in particular one which does not have the disadvantages of the prior art. Summary of the invention

[0008] An aim of the present invention is therefore to propose a method for broadcasting by a watch an informative message relating to an evaluation of the quality of life which is reliable and simple to implement.

[0009] For this purpose, the invention relates to a method of broadcasting by a watch an informative message relating to an evaluation of the quality of life of a wearer of said watch, according to claim 1.

[0010] In other embodiments: a first selection criterion provides that at least one environmental measurement of the descriptive data of each event episode relating to each type of environmental event is compared to a reference threshold for disruption of the quality of life; a second selection criterion consists of comparing a duration of each event episode relating to each type of environmental event to a reference threshold for the duration of disruption of the quality of life; the identification step comprises a sub-step of generating an indicator of disruption of the quality of life for each type of environmental event disrupting the quality of life identified;the generation sub-step includes a phase of calculating the quality of life disruption indicator for each type of environmental event disrupting quality of life identified from the following descriptive characteristics: ▪ an average value of the environmental measurement(s) included in the descriptive data of the selected event episodes relating to this type of environmental event; ▪ a total duration of the course of this type of environmental event; ▪ the number of selected event episodes of this type of environmental event; ▪ start and end times of the selected event episodes of this type of environmental event;the determined period is automatically defined by the processing unit by being initiated as soon as a first event episode of a type of environmental event is identified, and completed when a duration of exposure of the wearer to at least one type of environmental event considered to be disruptive to the quality of life is greater than a reference duration threshold.;

[0011] The invention also relates to a system for broadcasting by a watch an informative message relating to an evaluation of the quality of life of a wearer of said watch implementing this method, the system comprising the following elements connected together: a processing unit, at least one environmental sensor and an interface for broadcasting visual and / or sound information.

[0012] The invention also relates to a watch comprising such a system.

[0013] Advantageously, the watch is a connected mechanical watch.

[0014] The invention further relates to a computer program comprising program code instructions for executing the steps of the method when said program is executed by a processing unit. Brief description of the figures

[0015] Other features and advantages will become clear from the description given below, for information purposes only and in no way limiting, with reference to the appended figures, in which: there figure 1 is a schematic representation of a watch comprising a system for broadcasting an informative message relating to an evaluation of the quality of life of the wearer of said watch, according to one embodiment of the invention, and the figure 2 is a flowchart relating to a method of broadcasting this informative message, according to the embodiment of the invention. Detailed description of the invention

[0016] On the figure 1a watch 100 is shown comprising the system 1 for broadcasting by this watch 100 an informative message relating to an evaluation of the quality of life of a wearer of said watch 100. Such a system 1 is included in the watch 100 which is preferably a connected mechanical watch 100 with a hybrid display. This system 1 more precisely comprises in a non-limiting and / or non-exhaustive manner: - - a processing unit 2 comprising hardware and software resources, in particular at least one processor cooperating with memory elements; - - an interface for broadcasting visual information 3 such as a hybrid display dial provided with a first analog display component and a second digital and / or alphanumeric display component; - - an interface for broadcasting sound information 4 such as a loudspeaker; - - a communication interface; - - at least one environmental sensor 5; - - at least one behavioral sensor 6, and - - at least one physiological sensor 7.

[0017] In this system 1, the processing unit 2 is connected, among other things, to the interfaces for broadcasting visual and sound information and to the environmental 5, behavioral 6, and physiological 7 sensors.

[0018] The system 1 in this watch 100 is capable of evaluating the wearer's quality of life preferably solely from at least one type of environmental event recorded during a determined period. Each type of event recorded is quantified from at least one event episode specific to it and which takes place during the determined period. Each event episode is characterized by descriptive data including in particular one or more measurements of an environmental parameter. This environmental parameter is a quantity relating to a characteristic of the environment in which the watch 100 and its wearer are present. Such a parameter is, in a non-limiting and / or non-exhaustive manner, relating to: a temperature, a humidity, an ambient noise level, the frequency of a continuous sound, an atmospheric pressure, an illumination, the quality of the air, the quantity of sunlight, the lack of light, etc.

[0019] For example, when the parameter corresponds to a “noise level”, an event episode is defined by the following descriptive data: - one or more measurements of this noise level are determined by at least one suitable environmental sensor 5 and transmitted to the processing unit 2; - the duration of the event episode which is calculated by the processing unit 2 and is for example 10 minutes, and - the start time 10 a.m. and the end time 10:10 a.m. are determined by the processing unit 2.

[0020] It is understood that at this stage this environmental event is linked to a "noise level", and that for this type of event several episodes with different descriptive data can then be estimated during the determined period. Subsequently, according to the process described later, if this type of environmental event is considered to be disruptive to the wearer's quality of life, it then becomes a "noise nuisance".

[0021] In this context, the environmental sensors 5 are specifically adapted to measure these environmental parameters. As we will see later, the other behavioral sensors 6 and physiological sensors 7 participate in carrying out measurements which can be used optionally by the processing unit 2 as part of the evaluation of the quality of life of the wearer. The behavioral sensors 6 are capable of measuring all types of behavioral characteristics of the wearer of the watch 100 such as, for example, the movements or gestures made by the latter during the determined period. To do this, these behavioral sensors 6 may comprise one or more inertial sensors of the accelerometer, gyroscope or miniature multi-axis gyrometer type such as multi-axis sensors manufactured in MEMS technology, capable of detecting angular velocities and linear accelerations along several axes associating accelerometers and / or gyroscopes.As regards the physiological sensors 7, they are capable of measuring parameters relating to the functioning of a wearer's organism such as, for example, pulse, blood oxygen saturation, skin impedance, blood pressure, respiratory rate, respiratory arrhythmia, skin temperature, sweat rate, blood oxygen saturation or blood flow rate.

[0022] Such a system 1 of the watch 100 is capable of implementing a method of broadcasting by the watch 100 this informative message represented on the figure 2 .

[0023] This method comprises a step 10 of recording by the processing unit 2 of descriptive data of at least one event episode of at least one type of environmental event recorded during a determined period. During this step 10, from the detection of the start of the determined period until the end of this period, the descriptive data of one or more event episodes of at least one type of environmental event are archived in the memory elements of the processing unit 2 of the watch 100. These descriptive data of each event episode include, in a non-exhaustive and non-limiting manner: - one or more environmental measurements determined by the corresponding sensors 5 and transmitted to the processing unit 2; - the duration of the event episode which is calculated by the processing unit 2, and - the start and end times of the episode which are determined by the processing unit 2.

[0024] It should be noted that the creation of an episode is linked to the identification by processing unit 2 of a variation in an environmental parameter relating to a corresponding type of environmental event.

[0025] In this context, the determined period can be defined automatically by the processing unit by being initiated as soon as a first episode of a type of environmental event is identified, and completed when the duration of exposure of the wearer to at least one type of environmental event considered to be disruptive to the quality of life is greater than a reference duration threshold.

[0026] Alternatively, the determined period can be predefined so that a quality of life assessment is carried out at regular intervals, for example every 4 hours. The start of this period can then be initiated by the wearer of the watch by activating a control element, for example a push button of this watch.

[0027] The method then comprises a step 11 of identifying at least one type of environmental event disrupting the wearer's quality of life from a processing of said descriptive data. To do this, this step 11 comprises a sub-step 12 of selecting one or more event episodes relating to each type of environmental event recorded during the period determined from at least one selection criterion. According to a first selection criterion, at least one environmental measurement of the descriptive data of each event episode relating to each type of environmental event is compared to a reference threshold for disruption of the quality of life. If said at least one measurement is greater than the reference threshold for disruption of the quality of life, then the episode can then be selected or preselected when the conditions of this selection are linked to the verification of a second selection criterion.This second selection criterion consists of comparing the duration of each episode relating to each type of environmental event to a reference threshold for the duration of disruption to quality of life. In this context, if the duration of the episode is greater than the reference threshold for the duration of disruption to quality of life, then the episode is selected.

[0028] The identification step 11 then comprises a sub-step 13 of detecting one or more types of environmental events disrupting the quality of life of the wearer of the watch 100, based on the event episodes that have been selected. This sub-step can provide for a given type of environmental event that the number of episodes of this event must be greater than a reference threshold to be detected.

[0029] Subsequently, the identification step 11 comprises a sub-step 14 of generating a quality of life disruption indicator for each type of detected / identified quality of life disruptive environmental event. This sub-step 14 comprises a phase 15 of calculating the quality of life disruption indicator for each type of quality of life disruptive environmental event identified from descriptive characteristics. These descriptive characteristics of each type of identified quality of life disruptive environmental event are as follows: - an average value of the environmental measurement(s) included in the descriptive data of the selected event episodes; - the total duration of the course of this type of environmental event disrupting the quality of life during the determined period of the watch 100 which is equal to the sum of the durations of the selected event episodes; - the number of selected event episodes; - the start and end times of the selected event episodes which make it possible to evaluate their effect / impact on the disruption of the quality of life cycles. Indeed, the determined period includes a succession of cycles with phases of slow quality of life, especially at the beginning of the night, which allows the body to recover physically, and paradoxical quality of life which corresponds to the moment when the wearer dreams and where he evacuates his nervous tension.

[0030] It should be noted that the calculation of the quality of life disturbance indicator is carried out based on one or more of these descriptive characteristics.

[0031] Furthermore, such an identification step 11 can be implemented as soon as the determined period ends or simultaneously with the recording step 10, i.e. as soon as this determined period begins.

[0032] The method then comprises a step 16 of estimating a quality of life evaluation index as a function of the quality of life disruption indicator relating to each type of identified quality of life disruptive environmental event. During this step 16, the processing unit 2 determines the quality of life evaluation index by calculating an average value of the quality of life disruption indicator(s) obtained during the generation sub-step 14. During this calculation, coefficients may be applied to certain indicators as a function of the nature of the type of quality of life disruptive environmental event to which they relate. Indeed, certain types of events may have a greater impact than others on the disruption of the quality of life.

[0033] It should be noted that, optionally, physiological and / or behavioral measurement data taken during event episodes can also be taken into account in the calculation of this index.

[0034] Then, the method comprises a step 17 of designing the informative message comprising the estimated evaluation index in anticipation of its broadcast to the wearer. Such an informative message may be an audio message or a visual message comprising a two-dimensional or three-dimensional graphic representation comprising the index. This message may comprise, in addition to the quality of life evaluation index, a recommendation to the wearer of the watch 100 relating to an attitude (or behavior) to adopt to improve this quality of life which is defined as a function of the value of this index and therefore of the level of the quality of life evaluated.

[0035] It will be noted that the method may also provide a step during which the wearer can share his or her assessment of the quality of life over the day by choosing, from a contextual menu displayed in a second display component of the dial, a criterion relating to the qualification of this quality of life over the day from a list of criteria including, for example, the following: a good day, a restful day, a difficult day, etc. This step then provides for archiving of this assessment by the wearer of the watch in the form of data, the processing of which by the processing unit may make it possible to improve the accuracy of the assessment of the quality of life by the present method and system.

[0036] The invention also relates to a computer program comprising program code instructions for executing steps 10 to 17 of this method when said program is executed by the processing unit 2 of the watch 100.
