Technological background

[0003] In the state of the art, such processes for managing illumination are implemented in particular within the framework of the process of visual examination of parts for possible identification of faults in the latter. Such methods conventionally provide for piloting of a lighting device aimed at ensuring suitable lighting of a zone of interest comprising the parts to be examined. During this piloting, the suitable illumination of this zone of interest may consist in the generation by this lighting device of an invisible light generating a fluorescence which is capable of highlighting the existence of defects revealed by the emission of a fluorescent light visible by a dye of a penetrating composition previously applied to the said part and which has been retained in the cracks or fissures of the latter.

Detailed description of the invention

In Figure 1 is shown a system for managing an illumination 1 of an area of interest 2, included in a user's working environment. This working environment comprising the System 1 is preferably defined in a room 10 of a building. In other words, in this room the only light sources are included in this System 1 or there may be in this room a light source such as daylight which is more or less diffused. Such a work environment comprises a support element 4 such as a desk or even a workbench, in the form of a tray, in particular rectangular, provided to support at least one object 3 included in the zone of interest 2 of this environment of work. Such an object 3 is in a non-limiting and non-exhaustive manner:

- a component of a watch movement such as a plate, a bridge, a wheel, a spring, a mass, or even a watch exterior component, such as a back, a clasp, a bezel, a dial, a aperture dial index;

- a piece of timepiece such as a watch;

- a piece of jewelry.

[0015] Such a system 1 contributes to the user performing with the naked eye the detection of functional, structural or aesthetic defects of the object 3 comprised in the zone of interest 2 of his working environment. In other words, this user performs such a detection or identification of a defect based on the visual perception that he has of this object 3. This visual perception can be defined as being the result of the interpretation that this user's brain makes of this object 3 . information relating to this object 3 and which is included in a light radiation captured by photoreception and entering through his pupils in such a way as to activate his receptive cells which are found in the retinas of his eyes. The signals produced by these cells are then transmitted by the optic nerve to the brain.

[0016] As we have previously mentioned, this zone of interest 2 can comprise at least one object 3 capable of being manipulated by the user. In this System 1, such an area of interest 2 can be:

- a space defined on the plate of the support element 4 when the object 3 is placed on this plate and then occupies a portion of the surface of this plate, or

- A volume defined above this plate and in which this object 3 is included when it is manipulated by the user.

[0017] A teile zone of interest 2 is likely to benefit from a particular illumination produced according to the vision profile of the user and/or at least one characteristic of the object 3.

Such a System 1 for managing the illumination of the area of interest 2 comprises a main lighting device 5a, 5b, 5c and a secondary lighting device 6 each provided with a plurality of light-emitting elements . Alternatively each lighting device 5a, 5b, 5c, 6 may comprise a single electroluminescent element which is coupled to a modulator. In this context, this modulator is capable of modifying the light spectrum of this diode as well as the intensity/amplitude, the orientation and/or the degree of directivity and/or the diffusion of the light radiation of this diode. A light emitting element comprises a light emitting diode and alternatively also a microlens or other optical means. It will be noted in a variant that an electroluminescent element may be devoid of such a diode.

In Figures 2 to 4 are described three variants of this main lighting device 5a, 5b, 5c. In a first variant 111ustree in Figure 2 the main lighting device 5a comprises a single lighting module 14 subsequently called "first lighting module". This first lighting module 14 is arranged above the plate of the support element 4 and in particular above the zone of interest 2 and therefore the object 3 included in this zone 2.

In a second variant shown in Figure 3, the main lighting device 5b comprises the first lighting module 14 arranged above the plate of the support element 4, and a panel 16 having reflectance properties light radiation coming from the first lighting module 14 towards the zone of interest 2. In this configuration, the panel 16 is defined in whole or in part around both the first lighting module 14 and the plate of the element support 4. This panel 16 extends vertically in height, from the horizontal plate of the support element 4 to an outer edge of a peripheral wall of the first lighting module 14. It is understood that a passage is arranged in this panel 16 so that the user can have visual or physical access to the object 3 likely to be placed on the tray, in order to possibly be able to manipulate it. In the context of physical access, the opening allowing this passage can be permanent or limited in time with, in the latter case, the panel 16 which is mounted sliding or rotating in this System in order to temporarily create such an opening. Regarding access

visual, an opening possibly provided with a filter can be arranged to allow the observation of the object, the filter being able to be polarized and also adjustable spectrally, spatially, and temporally.

In a third variant shown in Figure 4, the main lighting device 5c comprises the first lighting module 14 arranged above the plate of the support element 4 and a second lighting module 15 and a panel 17. This panel 17 is defined in whole or in part around both the first lighting module 14 and the plate of the support element 4. Such a panel 17 extends vertically in height, from the horizontal plate from the support element 4 to the outer edge of the peripheral wall of the first lighting module 14. With regard to the second lighting module 15, it is defined in whole or in part around this panel 17 and is extends vertically, being between the heights measured relative to the ground of the horizontal plate and the peripheral wall of the first lighting module 14. In this configuration, the panel 17 has:

- reflectance properties of the light radiation coming from the first lighting module 14 towards the zone of interest 2, and

- scattering properties so as to be traversed by light radiation coming from the second lighting module 15.

In this third variant of the main lighting device 5c, it is understood that a passage is provided in this panel 17 and in the second lighting module 15 so that the user can have visual and/or physical access to the object 3, likely to be placed on the board, in order to possibly be able to handle it. In the context of physical access, the opening authorizing this passage can be permanent or limited in time with, in the latter case, the panel 17 and the second lighting module 15 which are mounted sliding or rotating in this system. to temporarily create such an opening. With regard to visual access, an opening possibly provided with a filter can be arranged to allow observation of the object, the filter being able to be polarized and also adjustable spectrally, spatially and temporally.

[0023] The secondary lighting device 6 for its part comprises a lighting module 18 arranged at a height measured starting from ground level which is higher than that of the first lighting module 14 of the main lighting device 5a , 5b, 5c. This lighting module 18 of the secondary lighting device 6 is located above a peripheral zone of the plate of the support element 4 and therefore of the zone of interest 2 comprising the object 3. This module of lighting 18, generates homogeneous lighting in the surroundings of the stage.

These two lighting devices are controlled by a processing unit 7 of System 1. This processing unit 7, which may be a computer, comprises hardware and software resources, in particular at least one processor cooperating with memory elements. . This processing unit 7 is capable of executing instructions for the implementation of a computer program in order to ensure the management of the illumination of the zone of interest 2.

[0025] System 1 also comprises a database 8 to which processing unit 7 is connected. This database 8 comprises in particular:

- Vision profile data of users comprising physiological and biological data of users having a role in visual perception;

- object characteristics data relating to the physical, chemical, aesthetic, functional and structural characteristics of this object 3;

- user identification data;

- object identification data.

[0026] It will be noted that the physiological and biological data may be relative:

- at Tagus;

- the gender of the user,

- to characteristics of the ocular system (sensitivity to glare,) and

- ä characteristics of the user's nervous system;

- to characteristics of resistance and/or visual endurance.

[0027] It should be noted that these physiological and biological user data take into account:

- the period of the day, for example to take account of the circadian rhythm relating to the user,

- the date and year when the user uses the System;

- the geolocation of the System and therefore of the room comprising the System,

- the spectrum and intensity of daylight in the event that the room where the System is located is bathed in such light, and

- the characteristics of visual photobiological safety including for example the standards/safeties relating to a time of visual exposure Ile to a light wavelength.

On the other hand, with regard to the identification data of the objects, it will be noted that they can include two-dimensional or three-dimensional representation data of these objects describing in particular the shape, the dimensions and or the aesthetic aspect of each object 3 as well as data relating to the nature of the material constituting this object 3. These data may also include information data of the two-dimensional or three-dimensional bar code type which may be present on the object 3.

[0029] Such a System 1 also comprises:

- a device for identifying users 9 of System 1 provided for participating in the implementation of an Identification or authentication of the user based on well-known technologies of the state of the art, relating to biometric authentication or again to radio authentication and this, from user identification data archived in the database 8;

- an object identification device 11 implementing systems for capturing at least one image, associated with digital image processing algorithms. Such a device takes part in the identification of the objects 3 from the object identification data archived in the database 8;

- a device for monitoring the head 12 of users comprising systems for capturing at least one image, associated with digital image processing algorithms as well as an oculometer or pupillometry, this device is capable of:

• determining the movements and positions of the individual's head;

• interpret particular user facial expressions;

• identify changes in users' facial expressions;

• measure and record the ocular paths of the users by determining for example the direction or the orientation of the gaze of the user relative to the object 3.

- A device 13 for measuring the luminance of the object 3, perceptible to the user's eye. This device therefore comprises a luminance meter, a pupillometer and an oculometer.

[0030] Such a system can also comprise a device for measuring physiological and/or biological parameters of the user. To do this, this device can comprise for example a bracelet worn by the user provided with activity sensors such as a cardiac sensor, a motion detector or even a geolocation sensor. Such a device generates data which can be transmitted to the processing unit.

[0031] In this system 1, the processing unit 7 is connected to the devices 9, 11 for identifying users and objects, to the device for monitoring the head 12 of the users, to the device for measuring the luminance 13 as well as only to the device for measuring physiological and/or biological parameters.

[0032] With reference to FIG. 5, such a system 1 is provided for implementing a method for managing the illumination of the zone of interest 2 comprising said at least one object 3 capable of being manipulated by the user, said lighting being produced by the main lighting device 5a, 5b, 5c and the secondary lighting device 6.

[0033] This method comprises a step 20 for identifying the user and/or the object 3. A such step 20, depending on the configuration chosen for the operation of this method, aims to identify only the user or only the object 3, or even the user and the object 3. In this context, the identification of the user is then carried out by the processing unit 7 and the authentication device as well as from the data user authentication files archived in the database 8 of the System 1. Likewise, the identification of the object 3 is carried out from this processing unit 7 which cooperates with the object identification device 11, in using to do this the identification data of objects archived in this server.

[0034] Once the user and/or the object 3 has been identified, the method comprises a step 21 for configuring the illumination of the zone of interest 2 as a function of the profile of the identified user relating to vision and /or at least one characteristic of the object 3 identified. This configuration step 21 comprises a sub-step 22 for generating an instruction for controlling the lighting properties of the main lighting device 5a, 5b, 5c and/or of the secondary lighting device 6 according to perception criteria visual of object 3 by the user. The lighting properties of the main and secondary lighting devices include:

- the light spectrum of each light-emitting diode constituting each of these lighting devices;

- the intensity/amplitude of the light radiation from each light-emitting diode constituting each of these lighting devices;

- the orientation and/or the degree of directivity and/or the diffusion of the light radiation produced by all the diodeselectroluminescentes constituting each of these lighting devices, such as for example an integrating sphere.

[0035] In this method, the generation sub-step 22 comprises an evaluation phase 23 of the visual perception criteria from the vision profile data relating to the identified user and/or from characteristic data relating to the user. object 3 identifies. Such visual perception criteria can therefore be evaluated solely from the vision profile data of the identified user or solely from the characteristic data relating to the identified object 3 or even solely from the vision profile data and characteristic data when the user and the object 3 have both been identified. These criteria of visual perception aim to characterize/quantify a

optimal visual perception of the user as a function, when he has been identified, of his profile data such as the physiological and biological data, and of the characteristic data of the object 3 when the latter has been identified.

The generation sub-step 22 then comprises a phase 24 for determining a configuration of the lighting properties of the main lighting device 5a, 5b, 5c and/or of the secondary lighting device 6 as a function of these criteria of visual perception. Subsequently, the processing unit 7 produces from the configuration thus determined, the instruction for controlling the lighting properties of the main lighting device 5a, 5b, 5c and/or of the secondary lighting device 6 .

This configuration step 21 then provides a sub-step 25 for controlling the main lighting device 5a, 5b, 5c and/or the secondary lighting device 6 according to the instruction for controlling the properties of lighting. During the performance of this sub-step 25, the processing unit 7 executes the instruction for controlling the lighting properties of the main lighting device 5a, 5b, 5c and/or of the secondary lighting device 6, previously generated . Such a sub-step 25 comprises a phase 26 for modifying the following lighting properties of the main and secondary lighting devices a, 5b, 5c, 6 according to said control instruction:

- the light spectrum and/or the intensity/amplitude of the light radiation from all or part of the light-emitting diodes of the main lighting device 5a, 5b, 5c and/or of the secondary lighting device 6;

- the orientation and/or the degree of directivity and/or the diffusion of the light radiation emanating from the main lighting device 5a, 5b, 5c and/or from the secondary lighting device 6 for example from.

• the selective extinction or the selective ignition of light-emitting diodes of the main lighting device 5a, 5b, 5c and/or of the secondary lighting device 6, or

• the orientation of the light radiation from the main device and/or from the secondary lighting device 6, the diodes of which are each provided, for example, with a microlens or other optical means.

The method also includes a step 27 of re-evaluation of the visual perception criteria of the object 3 by the user. Such a step 27 comprises a sub-step 28 of identification of a state of fatigue and/or visual discomfort of the user likely to alter the visual perception by this user of the object 3. Such a state of fatigue and/or visual discomfort can, for example, cause or be the cause of a loss of attention or a lack or loss of concentration for this user. In this context, a state of user fatigue or even visual discomfort can be generated by illumination of the zone of interest 2 and more particularly of the object 3, which is not suitable. As part of the implementation of this sub-step 28, the processing unit 7 processes the data, in the sense that it receives the following devices:

• the user's head monitoring device 12;

• the device 13 for measuring the luminance resulting from a part of a surface of the object 3 on which the user's gaze is directed or is directed;

• the device for measuring physiological and/or biological parameters of the user.

In this context, the monitoring device transmits data such as an image or a sequence of images or even a video of the user's face on the basis of which data the processing unit 7 carries out a digital processing allowing for example to detect a particular expression of this face such as blinking of the eyelid indicating a state of fatigue or visual discomfort by frowning. As regards the luminance measuring device 13, it transmits to the processing unit 7 luminance measurement data relating to the part of the surface of the object 3 on which the viewer is looking or is looking. user, and determines for example as a function of a luminance reference value whether the measurement or measurements carried out reveal visual discomfort of the user generated by lighting of the zone of interest 2 and more particularly of this part of the surface of object 3 which is not suitable. Concerning the device for measuring physiological and/or biological parameters of the user, it transmits data for measuring the physiological and/or biological state of the user to the processing unit.

This re-evaluation step 27 also includes a correction sub-step 29 of the visual perception criteria if a state of fatigue and/or visual discomfort of the user is identified. Such a sub-step 29 comprises a phase for carrying out calculation operations by the processing unit 7 aimed at modifying the values of these visual perception criteria from a correction index characterizing the level of the state of fatigue and/or visual discomfort of the user which was detected during the identification sub-step 28.

[0041] Such a re-evaluation step 27 is executed periodically and this, according to:

- a predefined time interval which is configurable;

- detection of a change in direction/orientation of the user's gaze relative to the object 3;

Claims (17)

- detection of manipulation of the object 3; - A detection of a displacement of the object 3; - detection of a change in at least one optical property of the object 3; - detection of an observation by the user of a new part of the surface of the object 3; - detection of a variation of at least one physiological and biological parameter of the user [0042] The method comprises, following this re-evaluation step 27, a step 30 for configuring an illumination of the zone of interest 2 as a function of the re-evaluated visual perception criteria. This configuration step 30 includes a sub-step 31 for generating a new instruction for controlling the lighting properties of the main lighting device 5a, 5b, 5c and/or of the secondary lighting device 6 according to these criteria of visual perception reevaluated by the user. Then this step 30 includes a sub-step 32 for controlling the main lighting device 5a, 5b, 5c and/or the secondary lighting device 6 according to the new instruction for controlling the lighting properties. During the performance of this step 30, the processing unit 7 executes this new instruction for controlling the lighting properties of the main lighting device 5a, 5b, 5c and/or of the secondary lighting device 6, previously generated.
