Definitions
- the invention relates to a method and a system for diagnosing the unsuitability of a part to a morphological characteristic of a user of this part.
- morphology is understood here as comprising both that of static morphology, which is concerned with the study of forms at rest, and with dynamic morphology, which is concerned with the study of moving shapes.
- a corrective measure can be the realization of a new part which, this time, will be better adapted to the morphological characteristics of the user.
- a corrective measure can also be the realization of a new component or a new part of the part.
- the production of a new part of the part can for example consist of a repair of the part, that is to say in adding material to the part and/or removing material from the part.
- These embodiments may in particular consist of implementations of design methods followed or not by those of manufacturing methods.
- dynamic morphological characteristics result from the setting in motion of the parts of the user's body which were characterized by the static morphological characteristics during the design of the initial part.
- dynamic morphological characteristics designates morphological characteristics which were not measured during the design phase of the initial part, in particular because they appear when the user performs movements that are unknown or not taken into account. during the design phase.
- the invention aims to provide a method for diagnosing the mismatch of a part to a morphological characteristic of the user that is less restrictive and simpler to implement.
- the invention also relates to an automatic system for diagnosing the unsuitability of a part according to claim 3.
- FIG. 1 is a schematic illustration in perspective of a part intended to be worn by a user
- FIG. 2 is a schematic illustration of a system for diagnosing the unsuitability of the part of Figure 1 to the morphological characteristics of a user
- FIG. 3 is a flowchart of a method for diagnosing the unsuitability of a part to the morphological characteristics of a user.
- Figure 1 shows an initial mechanical part 4 intended to be used by a user.
- the user is a human being.
- Part 4 is a part designed to adapt specifically to the morphological characteristics of this user. To this end, these morphological characteristics of this user were measured by following a predefined measurement protocol during an initial design phase.
- part 4 is a pair of glasses comprising two lenses 6 and 7 and a frame 10 on which these lenses 6 and 7 are fixed.
- lenses 6 and 7 are intended to correct the user's view. They are therefore specifically designed for this user. To be fully effective, these lenses must also be correctly positioned with respect to the eyes of the user.
- Each of these glasses 6 and 7 extends mainly in a plane called hereafter "median plane".
- the median plane is the one that minimizes the differences, according to the least squares method, between this plane and the side of the lens closest to the user's eye in front of which the lens is located.
- the frame 10 here comprises two circles 12 and 13 which surround and grip, respectively, the glasses 6 and 7.
- Each circle comprises:
- the side edges 12int, 13int are those which are closest to the user's nose when the latter is wearing part 4.
- the outer side edges 12ext and 13ext are those which are farthest from the nose of the user when wearing part 4.
- the frame 10 is a frame made by 3D printing. It has been specifically manufactured according to the morphological characteristics of the user's head so that the 6.7 lenses are correctly positioned in relation to the user's eyes. To this end, typically, static morphological characteristics of the user's head have been measured, at rest, during a design phase of the part 4 and following a predefined measurement protocol which imposes a particular position of the head when performing these measurements. Such a predefined protocol generally makes it possible to improve the repeatability of these measurements.
- frame 10 is formed from a single block of material.
- Part 4 includes sensors for measuring physical quantities representative of the extent to which part 4 is adapted to the morphology of the user's head. These physical quantities are representative of the static and dynamic structural relationship which exists between the part 4 and the user when the user uses this part 4. Thus, the value measured for each of these physical quantities depends both on the structural characteristics of part 4 and static and dynamic morphological characteristics of the user.
- the physical quantities measured by the sensors of the part 4 are relative positions and orientations of certain parts of the part 4 with respect to the face of the user. These measured relative positions and orientations depend on the conformation of the part 4 and, in particular, on its dimensions. Moreover, these positions and orientations also depend on the morphological characteristics of the user's face since these positions and orientations are measured by taking these morphological characteristics as references. It is recalled here that these positions and orientations can also depend on dynamic morphological characteristics of the user, which cannot be measured under the design conditions of the initial part. These dynamic morphological characteristics characterize, for example, amplitudes, angles, speeds or any other properties of the movements of the user during actual use of the part 4.
- the sensors of part 4 measure physical quantities representative of the position of a lens in relation to the face of the user or to the eye of the user in front of which this lens is located when the user wears part 4. These are the following physical quantities:
- the optical center is located on a horizontal optical axis passing through the center of the pupil of the user's eye when the user's head is vertical and he is looking at the horizon in front of him.
- the user's head is said to be vertical when he holds it straight.
- the position of the optical center relative to the upper or lower edge of the lens is the distance between the projection of this edge on the median plane and the point of intersection between this median plane and the optical axis.
- the projection of the edge on the median plane is carried out in a direction parallel to the optical axis. The distance is measured in the median plane when the user wears part 4 and holds his head vertical.
- the position of the optical center relative to the side edge of the lens is the distance between the projection of this side edge on the median plane and the point of intersection between this median plane and the optical axis.
- the projection of the edge on the median plane is carried out in a direction parallel to the optical axis. In this case, the distance is measured horizontally in the median plane when the user wears part 4 and holds his head vertical.
- the pantoscopic angle is an angle which represents the inclination of the median plane when the user wears the part 4 and holds his head vertical.
- this pantoscopic angle substantially corresponds to the angle between this median plane and the frontal plane of the user.
- the frontal plane is the vertical plane known in the anatomy reference system as dividing the user's body into an anterior or ventral portion and a posterior or dorsal portion. It is essentially parallel to the user's forehead.
- the pantoscopic angle depends on the conformation of the part 4 and the morphological characteristics of the user such as the conformation of his nose.
- the curvature angle represents the curvature, in the horizontal plane containing the optical center of the eye, of the front face of the pair of glasses when the user wears them.
- this angle of curvature corresponds substantially to the angle between a first and a second straight line.
- the first line is defined by the intersection between the median plane and a horizontal plane passing through the optical center.
- the second straight line is defined by the intersection between this same horizontal plane and the frontal plane of the user.
- the curvature angle depends on the conformation of the front face and the branches of the part 4, as well as the shape of the user's face.
- the sensors are fixed on the circles 12 and 13.
- the arrangement of the sensors fixed on the circle 13 is, typically, the symmetrical arrangement of the sensors fixed on the circle 12 with respect to the sagittal plane of the user.
- the sensors integrated into the circle 12 are described in more detail.
- Exhibit 4 has several rangefinders attached to the upper 12sup and lower 12inf edges.
- the circle 12 comprises three rangefinders 20 to 22 fixed to the border 12sup and three rangefinders 23 to 25 fixed to the border 12inf. These rangefinders are fixed in the circle 12 so as to be flush with its face closest to the face of the user. These rangefinders are spaced from each other along each of the borders.
- the range finders 20 and 23 also belong to the inner border 12int.
- the rangefinders 22 and 25 also belong to the outer edge 12ext. Each of these rangefinders 20 to 25 measures the distance between:
- the predetermined and fixed direction is orthogonal to the median plane.
- the mean value of the measurements of the range finders 20 to 25 is a value representative of the distance between the lens 6 and the user's eye.
- the gap between the measurements of the rangefinders 20 to 22 and the measurements of the rangefinders 23 to 25 makes it possible to calculate a value representative of the pantoscopic angle.
- the difference between the measurements of the rangefinders 20, 23 and 22, 25 makes it possible to calculate a value representative of the angle of curvature.
- Exhibit 4 also includes a camera 28 whose lens is turned towards the user's eye.
- This camera is fixed in the circle 12 so as to be flush with its face closest to the face of the user.
- This camera 28 takes photos of the user's eye in front of which the lens 6 is located. From these photos, it is possible to extract the position of the optical center of this eye with respect to the edge of the lens 6.
- the position of the camera 28 relative to the edge of the lens 6 is fixed and known.
- the position of the optical center is taken equal to the average of the positions of the center of the pupil measured over a long period of time.
- long period of time is meant here a period greater than 1 hour and, preferably, greater than a day or a week or a month.
- this average position of the pupil coincides with the position of the optical center.
- This measured position is expressed in a marker linked to the frame 10. Since the position of the camera 28 and the positions of the lower, upper and lateral edges of the lens 6 are also known in this marker, the position of the optical center of the eye with respect to each of the edges of the lens 6 is calculated.
- the part 4 also includes a diagnostic module 30 connected to each of the sensors of the part 4.
- the module 30 is fixed on the frame 10 and, for example, on the circle 12.
- the module 30 processes the measurements sensors to determine if the part 4 is correctly adapted to the morphology of the user's head. In case of mismatch, the module 30 sends a mismatch signal.
- the module 30 is described in more detail with reference to Figure 2.
- Figure 2 shows an automatic system 48 for diagnosing the unsuitability of the part 4 to the morphological characteristics of the user.
- This system 48 comprises part 4 and a device 50 for producing a new part 4.
- a device 50 for producing a new part 4.
- the module 30 of part 4 is shown.
- the module 30 comprises:
- an interface 32 to acquire the measurements of the various sensors of the part 4;
- a man-machine interface 34 in particular for transmitting a first maladjustment signal perceptible by the user;
- a memory 38 comprising the instructions necessary to execute the method of FIG. 3;
- a microprocessor 40 capable of executing the instructions recorded in the memory 38;
- the man-machine interface 34 here comprises a diode which, when lit, signals to the user that the part 4 is no longer suited to its morphological characteristics. In this case, the first mismatch signal to the user is emitted light.
- the transmitter/receiver 36 is a short distance wireless transmitter.
- it is a transmitter/receiver that complies with the Bluetooth standard and, preferably, complies with the BLE (Bluetooth Low Energy) standard.
- Transmitter/receiver 36 transmits a second mismatch signal to device 50.
- This second mismatch signal is not perceptible to the user. Here, it contains where the measured values for the physical quantities.
- the second mismatch signal is transmitted by the module 30 in response to the detection, by the module 30, of a mismatch of the part 4 to the morphological characteristics of the user.
- the memory 38 includes, in addition to the program instructions executed by the microprocessor 40, a predetermined set of conditions. When this predetermined set of conditions is satisfied by the values measured for the physical quantities, the part 4 is considered to be adapted to the morphological characteristics of the user. Otherwise, the part 4 is considered to be unsuitable for the morphological characteristics of the user.
- These conditions are in particular parameterized by expected values for each of the values measured for each physical quantity. More precisely, here, it is the comparison of the values measured for the physical quantities with the values expected for these physical quantities which makes it possible to diagnose whether the part 4 is adapted or not to the morphological characteristics of the user.
- the source 44 typically includes a battery capable of storing enough energy to power the various components of the module 30 for a long period of time.
- this battery is rechargeable.
- the source 4 comprises an interface for connecting it to an external charger.
- the device 50 is capable of automatically producing, from the measured values transmitted by the transmitter/receiver 36, a new part or part of a part better suited to the morphological characteristics of the user. For example, here, device 50 automatically makes a new mount for the user. The dimensions and conformation of this new frame are different from the dimensions and conformation of the initial frame 10 in order to obtain better adaptation between the morphological characteristics of the user and the new pair of glasses comprising this new frame. In this embodiment, the device 50 is typically located at the eyewear manufacturer and not at the user.
- the device 50 comprises:
- a transmitter/receiver 52 capable of establishing a wireless communication link 53 with the transmitter/receiver 36 in order in particular to receive the mismatch signal emitted by the module 30;
- a memory 58 comprising the instructions necessary to execute the method of FIG. 3;
- microprocessor 60 capable of executing the instructions recorded in the memory 58
- bus 62 for transmitting information between the various components of the device 50.
- the man-machine interface 54 includes a screen and one or more keys operable by an eyewear maker.
- the machine 56 is for example an additive manufacturing machine such as a 3D printer. Such a machine deposits successive layers of polymer or metal, for example, to manufacture the frame.
- the memory 58 includes instructions from a computer-aided manufacturing module 64.
- This module 64 includes in particular a digital model of the model of the frame 10 parameterized by the differences between the measured values of the physical quantities and the expected values for these physical quantities.
- the expected values are predetermined constants.
- the expected values are predetermined independently of the morphological characteristics of a particular user. These are target values to be reached so that part 4 is considered to be correctly adapted to its user. These target values are for example chosen by the eyewear manufacturer or fixed by the manufacturer of the lenses or by any standard applicable in the matter. Thus, as soon as the measured values of these physical quantities are known, all the dimensions of the new frame to be produced are known.
- the module 64 is capable, when it is executed by the microprocessor 60, of generating a command file executable by the machine 56.
- the machine 56 executes this command file, it automatically manufactures a frame whose conformation and dimensions are identical to those of the model parameterized by the values measured for the physical quantities.
- the process begins with a phase 80 of production of the initial part 4.
- the initial part 4 is manufactured.
- the user chooses, among a large number of frame models, the model he likes.
- the chosen frame model is made by the device 50 to obtain the frame 10.
- the device 50 receives, via the man-machine interface 54, values measured, at rest, for static morphological characteristics of the user and an identifier of the chosen frame model.
- the measurements of the static morphological characteristics were typically made during a preliminary design phase of the initial part 4 under so-called initial part 4 design conditions.
- the apparatus 50 automatically establishes the dimensions of the frame which must make it possible to obtain the expected values of the physical quantities when this frame is worn by this user.
- the microprocessor executes the module 64 to generate the command file of the machine 56.
- the eyewear manufacturer can then trigger the manufacture of the corresponding frame 10.
- the machine 56 then manufactures the frame 10.
- the eyewear manufacturer permanently assembles the lenses 6 and 7, the various sensors and the diagnostic module 30 on the frame 10 and obtains the part. 4 initial.
- the expression “permanently assemble” here designates the fact that the lenses 6, 7, the sensors and the diagnostic module 30 remain fixed on the frame 10 during actual use of this frame 10. In other words, this assembly permanent ensures that the lenses 6, 7, the sensors and the diagnostic module 30 are worn by the user each time the frame 10 is worn by this user. However, this does not prevent these elements from being dismantled if necessary and without damaging part 4, for example, to be replaced.
- the expected values for each of the physical quantities measured using the sensors of the room 4 will be recorded in the memory 38.
- a predetermined set of conditions on the measured values of the physical quantities is also stored in the memory 38.
- This set of conditions includes in particular conditions on the difference between the measured value and the expected value for each physical quantity. These conditions are satisfied if the difference between the measured value and the expected value for each physical quantity remains between a predetermined threshold S min and a threshold S max . As soon as the deviation crosses one of these thresholds S min and S max , the condition is no longer satisfied and the set of conditions is therefore no longer satisfied.
- the expected values and the predetermined set of conditions are stored in the memory 38, for example, by the device 50 and via the wireless link 53.
- the initial part 4 thus produced is then given to the user.
- a phase of actual use of this part 4 by the user then begins.
- This phase of actual use extends over a long period of time.
- the phase of actual use comprises periods of use of room 4 and periods of absence of use of room 4. During the periods of use, room 4 is continuously used and carried by the user. During periods of absence of use, part 4 is not used and is not worn by the user.
- a phase 84 of verification of the adaptation of this part 4 to the morphological characteristics of the user is executed.
- the duration of this verification phase 84 is adapted to the type of mismatch to be detected.
- the duration of phase 84 is preferably short compared to the expected service life of the initial part 4.
- the duration of phase 84 is typically of the order of a few thousandths to a few hundredths of the expected lifetime of the initial part 4, for example between 0.4% and 5% of this expected lifetime.
- the duration of phase 84 can be long compared to the expected lifetime of the initial part 4, typically of the same order of magnitude as this expected lifetime, for example greater than 25%, 50%, 100%, or 150% of this expected life.
- the sensors integrated into the mount 10 each perform their own measurement.
- the module 30 acquires the measurements made by the sensors of the mount 10.
- the module 30 processes these measurements. This processing consists here in executing, in order, the following two operations:
- a period of absence of use is detected from the same sensors as those used to establish the measured value of each of the physical quantities of interest.
- the module 30 seeks to identify the presence of an eye in the image taken by the camera 28. For this the module 30 searches in image a pattern characteristic of the presence of an eye. For example, this pattern can be a pupil, the white of the eye, an eyebrow or other. If this search is unsuccessful, a period of absence of use is detected. Otherwise, a period of use is detected.
- the module 30 records the measurements of the rangefinders 20 to 25 and compares the measured distances to a threshold S U di.
- the value of the threshold S u «i is chosen so that this threshold is exceeded only when the part 4 is not worn. If the distance measured by the majority of the rangefinders 20 to 25 is greater than this threshold S u ui, a period of absence of use is detected. Otherwise, a period of use is detected.
- step 90 If a period of absence of use is detected during step 90, the method immediately returns to step 86 without executing the following steps.
- step 90 If a period of use has been detected during step 90, then, during a step 92, the module 30 verifies whether the set of conditions is satisfied by the values measured for the physical quantities.
- the module 30 sends a mismatch signal.
- the maladjustment thus reported may be due to an a priori maladjustment to the actual conditions of use or the appearance of a need for adaptation of the part 4 to the morphological characteristics of the user considered globally.
- step 94 is executed.
- the method returns to step 86 without executing step 94.
- the transmission of the mismatch signal is then inhibited.
- Step 86 and the following steps are repeated at regular intervals at least for a cumulative duration DC of use.
- the duration DC is equal to the sum of the durations of a succession of consecutive periods of use.
- the duration of the regular interval is less than five minutes or one minute and the DC duration is greater than 48 hours or 72 hours or 300 hours.
- the duration of the regular interval is generally greater than one second or ten seconds. In this case, beyond the duration DC, the execution of phase 84 can be systematically interrupted.
- the duration of the regular interval is much longer.
- the duration of the regular interval is greater than a day or a week or a month or a year.
- the cumulative DC duration is also much longer.
- the DC duration is greater than one, three, or six months, greater than one year, or greater than two years, or greater than five years.
- a phase 100 of production of a new part 4 can then begin.
- connection 53 between the module 30 of room 4 and the device 50 is established.
- the module 30 transmits a mismatch signal to the device 50 via this link 53.
- the mismatch signal transmitted to the device 50 includes the values measured physical quantities which caused the triggering of the emission of this maladjustment signal. These measured values are then acquired by the microprocessor 60.
- the microprocessor 60 replaces, in the digital model of the frame model chosen by the user during step 80, the parameters which correspond to the physical quantities measured by the measured values acquired during step 104.
- module 64 is executed, which transforms the model parameterized by the acquired values into a command file. This command file is then transmitted to the machine 56.
- the machine 56 executes the new command file received. This leads the machine 56 to manufacture a new frame sized and shaped according to the measured values acquired during step 104. This new frame is specifically sized and shaped so that, when worn by the user, the predetermined play of conditions is satisfied again. As during phase 80, once the new frame has been manufactured, the eyewear manufacturer permanently assembles the lenses 6 and 7, the various sensors and the module 30 on this new frame. During the production of the new part 4, generally, the expected values and the set of conditions recorded in the memory 38 are the same as those recorded in this memory 38 in the initial part 4 because the frame model is the same.
- phase 100 ends and a new phase of actual use begins.
- phase 84 is executed again, but this time with the new part 4 and not with the initial part 4.
- the diagnostic module 30 is not incorporated into the part 4.
- the module 30 is incorporated into the apparatus 50 for producing the new part 4.
- the measurements of the sensors are recorded in the memory 38 and transmitted to the diagnostic module 30 via the link 53. Consequently, for a mismatch signal to be emitted, the user must carry the part 4 in a zone which allows the transmission of the measurements from the sensors to the module 30 integrated in the device 50.
- the sensors of the room 4 transmit their measurements to the user's mobile telephone as they occur. In response, the mobile telephone sends these measurements to the diagnostic module 30 integrated in the device 50 via a wide-area information transmission network, such as a cellular network.
- the condition set has alternative conditions.
- the set of conditions is satisfied from the moment when at least one of the alternative conditions is satisfied.
- the transmission of the mismatch signal from the module 30 to the device 50 can be done via any information transmission network and not necessarily via a short-distance wireless link. In particular, this can be done via a long-distance information transmission network, such as for example a cellular network.
- the module 30 integrated in room 4 transmits the maladjustment signal to the mobile phone of the user. The mobile phone then relays the mismatch signal to device 50 via a cellular network.
- the mismatch signal does not include the measured values of the physical quantities.
- the maladjustment signal is a simple auditory or visual or tactile signal perceptible by the user. An appointment can then be made with the eyewear manufacturer, on his initiative in response to his receipt of the unsuitability signal. Alternatively, in response to the perception of this signal, the user must then go to the eyewear manufacturer who then proceeds again to the measurements necessary for the production of a new part 4 adapted to his morphological characteristics. In the latter case, the module 30 is not necessarily capable of sending the measured values of the physical quantities to an external device such as the device 50.
- the man-machine interface 34 comprises a button which, in response to its depression, systematically triggers the transmission, by the transmitter/receiver 36, of the values measured for the physical quantities.
- the measured values are not transmitted solely in response to the detection of a mismatch between the part and the morphological characteristics of the user.
- the man-machine interface 34 is omitted. In this case, it can be replaced by a man-machine interface mechanically independent of part 4.
- the man-machine interface is integrated into the user's mobile telephone.
- the mismatch signal is only transmitted to the device 50. In the latter case, it is the man-machine interface 54 or the production of a new part which informs the user that the part 4 initial is no longer adapted to its morphology.
- man-machine interface 34 can comprise instead of, or in addition to, the diode:
- a loudspeaker to generate a sound which signals to the user that room 4 is no longer suitable
- the source 44 includes a battery charger capable of charging the battery by capturing the energy present in the external environment of the room 4.
- the source 44 comprises a photovoltaic panel or a transducer of movements into electrical energy.
- part 4 includes means for adjusting its conformation.
- this pair of glasses comprises screws which make it possible to adjust the spacing of the arms of this pair of glasses.
- the production of the new part can simply consist in adjusting these adjustment means.
- the part obtained is new because it has a different conformation from the initial part.
- the gap between the arms of the pair of glasses is different from that observed in the initial pair of glasses.
- the production of a new part does not necessarily imply the implementation of manufacturing steps for part or all of this part.
- the device 50 can be omitted or replaced by a man-machine interface which simply displays the measured values of the physical quantities without comprising any machine. manufacturing such as machine 56.
- the production of the new part can also consist of adding material to the initial part and/or removing material from the initial part.
- the device 50 can also be an automatic adjustment device for the part 4 capable of automatically adjusting these adjustment means.
- the new part differs from the initial part not by its dimensions but by the material in which the new part is made.
- the new part produced is identical to the initial part except that it is made of a material with different mechanical properties.
- it is made of a material having a Young's modulus less than 0.8 Yini or greater than 1.2 Yini, where Yini is the value of the Young's modulus of the material used to make the initial part.
- the device 50 is replaced or supplemented by a machine for machining corrective lenses.
- the apparatus 50 automatically manufactures new lenses for the user.
- the machine 56 is capable of manufacturing the frame 10 is a computer-aided subtractive manufacturing machine.
- the machine 56 is replaced or supplemented by a machining machine, a plastic injection or injection molding machine, an assembly machine or the like. More generally, the machine 56 can be any manufacturing machine in the Industry 4.0 domain or any computer-aided manufacturing machine.
- frame 10 is fabricated by a non-computer aided manufacturing machine.
- the device 50 is capable of producing at least part of the new part.
- the machine 56 can be very different from that described with reference to the figures.
- teaching given here in the particular case of a frame of a pair of glasses can be transposed without particular difficulty to other parts or parts of parts other than that of a pair of glasses.
- the part can also be chosen from the group formed:
- a helmet such as a glove, trousers or a jacket, a shoe,
- the device that manufactures the initial part is not necessarily the same as the device that manufactures the new part. Alternatively, it can be two different devices.
- the assembly of glasses 6 and 7 and/or sensors can also be automated and therefore carried out automatically by a machine.
- the predetermined set of conditions is stored in the memory 38 using a programming unit of the module 30 independent of the device 50.
- the rangefinder 20 or 23 is compared to the threshold S u «i. If the distance measured by this rangefinder 20 or 23 exceeds this threshold, then a period of absence of use is detected. In another embodiment, it is the mean of the distances measured by the rangefinders 20 to 25 which is compared with the threshold S u «i. In certain embodiments, when the distance which separates a rangefinder from its target is greater than the threshold S uti i, the rangefinder delivers an identifier which indicates that the target is too far away for a distance measurement to be carried out. In this case, it is the presence of this identifier which is used to detect a period of absence of use.
- the detection of periods of use and absence of use is omitted. This is for example the case if the part is a part, such as a prosthesis, permanently worn by the user during the phase of actual use.
- the mismatch signal and the measured values of the physical quantities which triggered its emission can be stored in the memory 38 at a time when the user was wearing the part 4. Then, subsequently, the stored mismatch signal is transmitted to the device 50. Thus, the presence of the user during phase 100 is not necessary.
- the new part does not include the sensors or the diagnostic module.
- the method does not return to phase 84 but continues with an ordinary phase of use of the new part 4 without the possibility of detecting its inadequacy to the morphological characteristics of the user.
- the sensors can be integrated into part 4 in another way.
- the camera 28 is fixed on the glass 6 and not on frame 10.
- rangefinders 20 to 25 can also be attached directly to lens 6 and not to frame 10.
- the integration of the sensors in the part 4 can also be carried out in such a way that these sensors are not removable. In this case, it is not possible to disassemble the sensors without damaging part 4.
- the man-machine interface 34 is able to acquire a command from the user to trigger the phase 84 of verification of the adaptation of the part 4 to its morphological characteristics.
- the man-machine interface 34 includes a button. When this button is pressed, module 30 executes phase 84. When the button is released, the execution of phase 84 stops. In this case, the detection of periods of use and non-use can be omitted.
- the user stands straight and gazes fixedly at the horizon in front of him until that he ends the execution of this phase 84 by releasing the button.
- an external and independent apparatus of the part 10 can be used to display a target that the user must look at.
- the physical quantity representative of the unsuitability of the part to the morphological characteristics of the user depends on the part.
- the physical quantity measured can be chosen from the group consisting of the following physical quantities:
- a pressure sensor can be implanted in one of the arms of the pair of glasses to measure the pressure exerted by this arm on the user's head.
- a temperature, vibration or color sensor can be integrated into a part such as a shoe to measure a physical quantity representative of the friction between the skin and the shoe. Indeed, this friction produces heat and vibrations.
- part 4 may include an additional sensor only used to detect periods of use and absence of use.
- this additional sensor can be the pressure sensor described above or a temperature sensor.
- the performance of measurements, by the other sensors which measure the physical quantity of interest can be inhibited for the entire duration of each period of absence of use.
- the initial morphological characteristics can be morphological characteristics measured on the user, for example by means of an application of a mobile terminal of the user such as a smart telephone or a tablet and transmitted by the user , or standard morphological characteristics pre-recorded and supposed to be suitable for all users.
- the initial morphological characteristics used to manufacture the initial part 4 are not necessarily measured on the user.
- part 4 During a phase of actual use of part 4, it is generally not used permanently by the user. The fact of detecting the periods of absence of use of the part 4 therefore makes it possible to take into account, to establish the diagnosis, only the measured values constructed from measurements carried out during the periods of use of the part 4 by the 'user.
