TITLE

Method of changing a display on a computerized apparatus screen of a health condition of a patient and computerized apparatus

DESCRIPTION FIELD OF THE INVENTION

The present invention relates to a method for modifying a display on a screen of a computerized apparatus of a health status of a patient and computerized apparatus which is capable of realizing it.

STATE OF THE TECHNIQUE

According to a very common typology, visualizations of this kind correspond to temporal graphs that develop according to a first direction or parametric direction, generally vertical (?ordinate axis?), and according to a second direction or temporal direction, generally horizontal (?ordinate axis). abscissa?).

AND? known to modify the display for example by enlarging (so-called ?zoom-in?) according to the vertical axis and/or according to the horizontal axis or decreasing (so-called ?zoom-out?) according to the vertical axis and/or according to the? Horizontal axis.

Thanks to ?touchscreens?, i.e. touch-sensitive screens, used especially in devices called ?tablets? and "smartphone", the enlargement and reduction changes can be obtained through gestures that the user of the device makes by touching the screen. A well-known gesture consists in placing the fingertips of the thumb and the fingertips of the index finger close to the screen at a certain mutual distance and in varying this distance (i.e. bringing the fingertips closer or further apart) as the fingertips move closer to the screen.

Furthermore, ? I know how to modify the display in other ways, for example by scrolling (so-called ?scroll?); even scrolling can? be obtained through gestures.

The Applicant has filed a previous patent application relating to a method for displaying on a screen of a computerized device a temporal trend of a patient's state of health; according to this method, for each instant in time, values of various health parameters are combined according to a mathematical formula obtaining a plurality? of aggregate values. This patent application? incorporated herein by reference and set forth at the end of this description.

A similar visualization method could be applied, for example, to temperature. Having available the temperature values recorded daily in various cities? of a region, an aggregate parameter corresponding to the average temperature in the region could be defined, and a display of the temporal trend of the average temperature in the region could be generated on the screen.

In the case of temperature, a traditional magnification according to the parametric direction would lead to a more accurate visualization. accurate measurement of variations in average temperature, i.e. a quantitative improvement.

SUMMARY

General purpose of the present invention? that of providing a method for modifying a visualization that modifies the visualization at least from a qualitative point of view (it could be an ?increase? in quality? or a ?decrease? in quality?, which does not mean a worsening of the visualization) and, possibly , even from the quantitative one.

This general purpose as well as? other more purposes? specifications are achieved thanks to what is expressed in the attached claims which form an integral part of this description.

LIST OF FIGURES

The present invention will result more? clear from the detailed description that follows to be considered together with the attached drawings in which:

Fig. 1 shows a first example of a time graph according to the present invention,

Fig. 2 shows a second example of time graph according to the present invention,

As can be easily understood, there are various ways of implementing the present invention in practice which are defined in its main advantageous aspects in the attached and non-attached claims? limited n? from the detailed description that follows n? from the attached drawings.

DETAILED DESCRIPTION

Fig. 1 shows a first example of a temporal graph 100 which corresponds to the visualization of the temporal trend of an "aggregate parameter" PA. Fig. 2 shows a second example of time graph 200 which corresponds to the visualization of the time trend of the "aggregate parameter" PA. AND? it should be noted that while in Fig. 1 the values of the PA parameter are displayed according to their actual value (for example between 0.3725 and 0.47), in Fig. 3 the values of the PA parameter are displayed, for example, according to their discretized value (e.g. between 7 and 9).

For both of these example graphs, the display time range is from t1 (for example, the year 2000) to t6 (for example, the year 2005), and the values are displayed annually.

For both of these example graphs, the horizontal x-axis corresponds to the time axis and the vertical y-axis corresponds to the parameter axis.

The PA parameter in these graphs? deliberately generic and refers to a ?state of health? of a patient. It could be any of the parameters discussed below with reference to Fig. 3 (or even a different one); but the best example? significant to explain the present invention? P20.

The ?state of health? of a patient can? be indicated by the value of various health parameters.

For example, the values of blood parameters obtained through a blood test of a person collectively indicate a certain ?state of health? of this person, but in a non-concise format.

The ?capabilities? preceptive? of a person indicate, taken together, a certain ?state of health? of this person (which has nothing to do with the ?state of health? referred to in the previous paragraph). There are five human senses (sight, hearing, smell, touch and taste) and if measurements are carried out on a person in relation to the various senses, their "capabilities" are quantified. perceptive?. ? I note that the ?capabilities? perceptive? of a person vary over time; for example, vision and hearing decline with age, but not in the same way for all people.

The ?capabilities? preceptive? of a person can be divided and grouped. For example, you can identify and group ?capabilities? precepts relevant to driving vehicles?, i.e. sight and hearing. Even the ?capabilities? precepts relevant to driving vehicles? they indicate, taken together, a certain ?state of health? (which is different with the ?state of health? referred to in the previous paragraph, even if connected).

The various possible health parameters of a person are very different from each other. Typically, values of different health parameters are measured with units? of different sizes. For example, vision is measured in diopters and hearing is measured in decibels.

By aggregating two (or more?) different health parameters of a person you can? provide a summary indication of a ?state of health? of this person and, in particular, can you? display it on a computer screen. For example, can you? foresee:

- that the computerized device stores health data relating to two (or more?) different health parameters of the patient,

- that for each parameter a plurality is stored? of absolute values of the parameter at different instants of time,

- that a scale is chosen to represent the "state of health", said scale being numerical (in particular discrete numerical),

- that the absolute values of the parameters are converted into relative values according to said scale,

- that the relative values of the parameters are combined for each instant of time according to a ?combination formula? (typically mathematics) obtaining a plurality? of aggregate values at different instants of time, e

- that a time graph of the aggregate values is displayed on the screen.

According to the present invention, the objective is set, for example, to modify, at least from a qualitative point of view, such a visualization of a ?state of health? of a patient.

Can this invention be done? apply (in particular it typically applies) to health parameters organized into two or more? (three, four, five, six, ?) levels as shown for example in Fig. 3 where there are three levels.

Parameters P1-P7 are first-level health parameters, parameters P10 and P20 are second-level health parameters, and parameter P100 ? a third level health parameter. Can you? display: the parameter P10 as an aggregation of the parameters P1 and P2 (all first level), the parameter P20 (which can be considered to correspond to the "state of health" PA of Fig. 1 and Fig. 2) as an aggregation of the parameters P4 and P5 and P6 (all first level), the parameter P100 as an aggregation of the parameters P10 and P20 (second level) and P3 and P7 (first level) ? depending on the case, the ?combination formulas? relating to these aggregations can be the same, similar or different. To explain even better, the parameter P1 can? be ?seen?, the P2 parameter can? be ?heard?, the P10 parameter can? be ?capacity? precepts relevant for driving vehicles?, the P20 parameter can? be ?capacity? mental issues relevant to driving vehicles?, and the P100 parameter can? be ?capacity? relevant to driving vehicles? (which include both physical and mental ones); could parameters P3 and P7 be other capabilities? specifications relevant for driving.

In the following it is assumed that Fig. 1 and Fig.2 refer to parameter P20.

Before entering into the merits of the description of the present invention, some gestures will be described, in themselves? well known, which can be used to implement it; the use of different gestures is not absolutely excluded.

Fig. 4 schematically shows a ?zoom-in? gesture. or "vertical" enlargement. The gesture consists in placing the fingertip of the thumb and the fingertip of the index finger close to a screen at a certain distance from each other and in increasing this distance (i.e. moving the fingertips apart) while the fingertips are brought closer to the screen. AND? called ?vertical? as the separation essentially develops along the vertical direction. Fig. 5 schematically shows a ?zoom-out? gesture. or "vertical" shrinkage. The gesture consists in placing the fingertip of the thumb and the fingertip of the index finger close to a screen at a certain distance from each other and in decreasing this distance (i.e. bringing the fingertips closer together) as the fingertips move closer to the screen. AND? called ?vertical? as the approach essentially develops along the vertical direction.

Fig. 7 schematically shows a ?zoom-in? gesture. or "horizontal" enlargement. The gesture consists in placing the fingertip of the thumb and the fingertip of the index finger close to a screen at a certain distance from each other and in increasing this distance (i.e. moving the fingertips apart) while the fingertips are brought closer to the screen. AND? called ?horizontal? as the separation essentially develops along the horizontal direction. Fig. 8 schematically shows a ?zoom-out? gesture. or "horizontal" shrinkage. The gesture consists in placing the fingertip of the thumb and the fingertip of the index finger close to a screen at a certain distance from each other and in decreasing this distance (i.e. bringing the fingertips closer together) as the fingertips move closer to the screen. AND? called ?horizontal? as the approach essentially develops along the horizontal direction. If the direction of departure or approach is not possible? consider ?essentially? vertical or horizontal, can you? plan to evaluate which direction is the ?prevalent? (for example compared to a 45 direction?).

Fig. 6 schematically shows a ?scroll? gesture or "vertical" scrolling. The gesture consists of placing the fingertip of the index finger close to a screen and moving it while keeping it close to the screen. AND? called ?vertical? as the movement essentially develops along the vertical direction. Similarly, can you? define a ?scroll? gesture or "horizontal" scrolling. The starting point for the following explanation? for example the parameter P20, understood as ?state of health? of a patient, displayed for example as shown in Fig.1 on a screen of a computerized device; the P20 parameter corresponds to the set of health parameters P4 and P5 and P6 of the patient aggregated together (through a certain formula); the initial display corresponds to a temporal graph 100 which defines a first direction or parametric direction PA and a second direction or temporal direction t. In response to a ?zoom-in? gesture according to the first direction (see for example gesture 400 in Fig.4 - the important thing is that the gesture is such that it can be associated with the first direction, i.e. the parametric direction) or with a ?zoom-out? gesture. according to the first direction (see for example the gesture 500 in Fig.5 - the important thing is that the gesture is such that it can be associated with the first direction i.e. the parametric direction) of a user of the device, a graph is displayed on the screen different time. It corresponds to a different set of patient health parameters; if the parameters of the different set are more? of one, these are aggregated together (through a certain formula which, typically, is different from the one used for the initial display).

In response to the ?zoom-in? gesture according to the first direction, the different set of parameters includes parameters of a lower hierarchical level. Starting from the P20 display, the ?zoom-in? leads for example to the display of P5 which ? the ?central? parameter in the lower hierarchical level; alternatively, it could lead to the display of P4 which is ? the first parameter in the lower hierarchical level or of P6 and the last parameter in the lower hierarchical level. In this example, the different set includes only one health parameter (and therefore no aggregation is necessary) since? the lower hierarchical level? the highest level? bottom of the hierarchy.

In response to the ?zoom-out? gesture according to the first direction, the different set of parameters includes parameters of a higher hierarchical level. Starting from the P20 display, the ?zoom-out? gesture leads to the display of P100. Does the different set include a plurality? of health parameter (P10, P3, P20 and P7) and therefore? necessary for them to be aggregated together.

According to some embodiments, the different set of parameters can depend on the amplitude of the gesture. For example, considering Fig. 3, a ?zoom-in? parametric large can? move from parameter P100 to parameter P2 or P3 or P5 or P7. For example, considering Fig. 3, a ?zoom-out? parametric large can? bring from parameter P5 to parameter P100.

Advantageously, you can? provide that the display according to the present invention includes not only a time graph, but also additional indications. For example, on the screen can? the acronym and/or name of the health parameter corresponding to the current display will also appear and possibly also the set of aggregate health parameters and possibly also the "combination formula"; with reference to Fig. 1 and Fig. 2, instead of the generic symbol PA the specific symbol P20 could be reported and possibly also P4, P5, P6. It is understood that many additional indications (of a textual and graphic nature) could be useful to the user; they could be displayed permanently (according to predefined settings) or at the user's request.

In response to a ?swipe? gesture according to the first direction (see for example the gesture 600 in Fig.6 - the important thing is that the gesture is such that it can be associated with the first direction i.e. the parametric direction) of a user of the device, a graph is displayed on the screen different time. It corresponds to a different set of patient health parameters; if the parameters of the different set are more? of one, these are aggregated together (through a certain formula which can be the same, similar or different from the one used for the initial display).

In response to the ?swipe? gesture according to the first direction, the set of different parameters includes parameters of identical hierarchical level. According to some implementation examples, the different set can depend on the direction of the movement of the gesture and/or the amplitude of the movement of the gesture.

For example, starting from the P20 display, the ?scroll? leads to the display of P10 whether the movement is upwards or downwards. For example, starting from the display of P5 the ?scroll? leads to the display of P4 if the movement ? upwards and P6 if the movement? downward. For example, starting from the display of P4 the ?scroll? with upward movement it can? lead, depending on the implementation, to the display of P3 or P6 (we can speak of "cyclic scroll" within the set). For example, a broad gesture can take you from P4 view directly to P6 view. In response to a ?zoom-in? gesture according to the second direction (see for example gesture 700 in Fig.7 - the important thing is that the gesture is such that it can be associated with the second direction, i.e. the temporal direction) or to a ?zoom-out? gesture. according to the second direction (see for example the gesture 800 in Fig.8 - the important thing is that the gesture is such that it can be associated with the second direction, i.e. the temporal direction) of a user of the device, the same is displayed on the screen time graph, but with a zoomed in or zoomed out time scale respectively.

With reference to Fig. 1 or Fig. 2, a ?zoom-in? horizontal, i.e. temporal, can? bring to the display (enlarged) for example of the same PA parameter of the time interval t1-t5 or t1-t4 or t1-t3 or t2-t6 or t2-t5 or t3-t6 or t2-t4 or t3-t5 or t4- t6 depending on the amplitude of the gesture and/or the position of the gesture.

In response to a ?swipe? gesture according to the second direction (is there not a figure that specifically represents it? could it be a gesture similar to that shown in Fig.6 but rotated by 90?) of a user of the device, a different time graph is displayed on the screen. It corresponds to a different time interval, but with the same time scale.

With reference to Fig. 1 or Fig. 2, a ?scroll? horizontal, i.e. temporal, starting from the visualization of the PA parameter in the time interval t3-t4 can? lead to the display of the same PA parameter in the time interval t2-t3 or t4-t5 (depending on the direction of the movement) or, if the gesture is ? wide, in the time interval t1-t2 or t5-t6 (depending on the direction of movement).

As anticipated, the method according to the present invention is particularly well suited to be implemented through a "touch-sensitive" screen; in this case, one or some or all gestures are detected by the screen. However, as is known, there are other ways to detect gestures, for example through a video camera.

AND? The subject of the present invention is also a computerized device equipped with a screen, a processor and memory, in which an electronic computer program is stored in the memory, and ? such as to implement the innovative method when the program? executed by the processor.

As can be easily understood, there are various ways of implementing the present invention in practice which are defined in its main advantageous aspects in the attached and non-attached claims? limited n? from the detailed description that follows n? from the attached drawings.

DETAILED DESCRIPTION

Will this invention come? described below with reference to the state of health of a patient linked to his ?capabilities? perceptive? why? the related examples are easy to understand, in particular the example relating to the ?capabilities? relevant precepts for driving vehicles?. This easy understanding should not, however, lead one to think that the invention is obvious. In fact, the idea of aggregating non-homogeneous health parameters is not? at all trivial especially if you consider it in the context of medical science, and it is? particularly advantageous especially as the number of aggregated parameters increases.

The idea of aggregating non-homogeneous health parameters? underlying the visualization of the temporal trend of at least one state of health of a patient according to the present invention which turns out to be effective because? simple and immediate to understand.

This invention? useful not only to doctors, but also to paramedics and patients.

As it is known ? already? mentioned previously, there are five human senses:

sight, hearing, smell, touch and taste.

The ?capabilities? preceptive? can be the subject of an initial ?state of health? of a patient (if it is considered that the person is suffering from an illness or disorder linked to his perceptive abilities), and they refer to all five senses.

The ?capabilities? precepts relevant to driving vehicles? can be the subject of a second ?state of health? of a patient, and can refer, for example, to sight and hearing.

The ?capabilities? precepts relevant to nutrition? can be the subject of a third ?state of health? of a patient, and can refer, for example, to taste and smell; but they could also refer in addition to touch and sight.

Will it be done in the following? reference to the same person who will come? called ?patient?.

Table 100 of Fig. 1A stores the absolute values of the parameter P1, i.e. the eyesight, of a person in the years from 2000 to 2005, assuming that a measurement in ?diopters? has been carried out? per year. The absolute values are for example the following:

2000 10 diopters

2001 10 diopters

2002 10 diopters

2003 9.5 diopters

2004 9 diopters

2005 8.5 diopters

Let's assume that they are all acceptable values for driving a vehicle, with the exception of the 2005 value.

Table 200 in Fig. 1B stores the absolute values of the parameter P2, i.e. hearing, of a person in the years from 2000 to 2005, assuming that a measurement in "decibel" has been carried out. per year. The absolute values are for example the following:

2000 10 decibels

2001 10 decibels

2002 15 decibels

2003 15 decibels

2004 20 decibels

2005 25 decibels

Let's assume that these are all acceptable values for driving a vehicle.

Table 110 of Fig. 2A stores the relative values of the parameter P1, which derive from the conversion of the absolute values of the table 100 of Fig. 1A using a scale ranging from 0 to 1, in which 1 indicates the optimal view (i.e. 10 diopters ) and the formula P1/10; the relative values are as follows:

2000 1.0 %

2001 1.0 %

2002 1.0 %

2003 0.95 %

2004 0.9 %

2005 0.85 %

The table 210 of Fig. 2B stores the relative values of the parameter P2, which derive from the conversion of the absolute values of the table 200 of Fig. 1B using a scale ranging from 0 to 1, in which 1 indicates the optimal view (i.e. 0 decibel ) and the formula 1-P2/50; the relative values are as follows:

2000 0.8 %

2001 0.8 %

2002 0.7 %

2003 0.7 %

2004 0.6 %

2005 0.5 %

Table 300 of Fig. 3 stores aggregate PA values obtained, for each year considered, by combining the relative values of parameters P1 and P2 according to a mathematical formula F; the formula ? the following:

PA(year) = (0.7 * P1r(year) 0.3 * P2r(year)) / 2 The aggregate values are as follows:

2000 0.47

2001 0.47

2002 0.455

2003 0.4375

2004 0.405

2005 0.3725

The acceptability? of these aggregate values will be? considered later. These aggregate values (which can be between 0 and 1) could be processed by discretizing them on a scale ranging for example between 0 and 20; the aggregated and discretized values are as follows:

2000 9

2001 9

2002 9

2003 9

2004 8

2005 7

The acceptability? of these aggregated and discretized values will be? considered later.

Fig. 4 shows a time graph 400 relating to the above aggregate values as it might be displayed on a computerized device screen, such as a desktop or laptop or a tablet or smartphone.

Fig. 5 shows a time graph 500 relating to the above aggregated and discretized values as it might be displayed on a screen of a computerized device, such as a desktop or laptop or a tablet or smartphone.

AND? It is evident how effective the visualization of the state of health ?capacity? precepts relevant to driving vehicles? even if deriving from a plurality? of non-homogeneous health parameters, i.e. vision and hearing, and the relative trend over time.

Furthermore, the ?aggregate view? also facilitates an ?aggregate evaluation? of the state of health. For example, if we first consider the sight parameter in isolation we come to the conclusion that the person could drive without problems up to and including 2004; if we then consider the hearing parameter in isolation we come to the conclusion that the person could drive without problems up to to 2005 (inclusive) and therefore, overall, it would be deduced that the person could drive without problems until 2004 (inclusive). Instead, if we consider the aggregation (and the related graphs 400 and 500), we could deduce that the capacities? perceptions as a whole have drastically reduced after 2003 and therefore already? in 2004 driving could have been problematic; this message? even more? evident from graph 500 which corresponds to an "aggregate and discretized" visualization. of the state of health.

Naturally, what is described above (and the related formulas) are only an example to be considered non-limiting of the present invention. Examples of visualization of other health states could have been given, for example with reference to what was explained previously, the health state related to the ?capabilities? precepts relevant to nutrition? or the state of health relating to all the ?capabilities? preceptive?. AND? It is clear that for the same person various ?states of health? choosing different health parameters.

A significant example of ?health parameters? ? consisting of blood parameters.

A significant example of ?health parameters? ? consisting of the ?ICF codes? (International Classification of Functioning, Disability and Health) with the related ?domains? and ?qualifiers?. Typically, for a single patient you will only have values available for a group of a few ICF codes, and the set considered for visualization purposes could correspond to a sub-set of the group; ? Is it also possible that it makes sense to define more? sub-sets within the same group.

However, according to the present invention, the ?health parameters? which can be aggregated for visualization purposes can be completely non-homogeneous and obtained through completely different tests.

Two aspects are important for utility purposes? practice of the present invention: the conversion formulas from the absolute values of the health parameters to the relative values of the health parameters, and the combination formula; the combination ? typically an ?aggregation function?, a term used in the computer industry.

The invention will come illustrated below in its generality; the previous example could? be useful for understanding what is expressed below.

How already? said, the method according to the present invention serves to display on a screen of a computerized device a temporal trend of at least one state of health of a patient.

The method involves the computerized device storing health data relating to a set of different health parameters of the patient; such data will be acquired and entered into the device before viewing, typically well before viewing; ? It is possible, indeed probable, that the device stores other data relating to the patient, in particular other health data relating to the patient in addition to those of the set considered here. Specifically, for each health parameter of the set considered here? memorized a plurality? of absolute values of the parameter at different time instants; in the example described previously we were referring to one piece of data for each year, but the period could be completely different (one piece of data per month, one piece of data per week, one piece of data per day, one piece of data per hour, etc.) and the data they could also refer to surveys/measurements that are simply repeated and not strictly periodic. How can this be seen from the example described? It is important that for each instant considered (which, as mentioned, can have a certain duration) there is an absolute value of each parameter of the set considered.

The method includes the steps of:

A) choose a scale to represent the health state considered; B) convert the absolute values of the parameters of the set into relative values according to this scale;

C) for each time instant combine the relative values of the parameters of the set according to a mathematical formula obtaining a plurality? of aggregated values at different time instants (which are the same time instants in which the parameters to be combined are defined) ? it is therefore an operation to be repeated identically for every instant in time; And

D) display a time graph of the aggregate values on the screen. The scale referred to in phase A of the method? numeric (for example between 0 and 1 or between 0 and 100), in particular discrete numeric (for example it could be an integer between 0 and 9).

The conversion referred to in phase B of the method can? also provide that not all the values of the scale are used, for example the scale goes from 0 to 9 but you choose to use only the values from 0 to 4.

The mathematical formula referred to in phase C of the method can? be very varied. As said previously ? typically an "aggregation function", for example a maximum function (bear in mind that not only the "absolute maximum" exists) or a minimum function (bear in mind that not only the "absolute minimum" exists) or a function of average (for example there is the linear average, the weighted average, the geometric average) or a linear combination or a linear combination; in the case of linear combination, the heart of the combination formula is the multiplicative coefficients. A good or optimal choice can? depend on the application and/or operator preferences.

Among the various possibilities, this formula could also advantageously include a discretization operation (see the difference between the 400 graph in Fig. 4 and the 500 graph in Fig. 5) to be carried out after the aggregation operation.

The set of health parameters according to the present invention (i.e. its composition) can be chosen by an operator among a plurality? of the patient's health parameters during the use of the computerized visualization device. Preferably, the whole can be modified, for example according to a patient pathology presumed by the operator. The whole can correspond to a choice previously made by an operator and stored in the device; for example, if an operator needs to evaluate a group of patients he can? be interested in the same set for all patients in the group.

One of the operator's possible choices for display purposes? the time period of interest; for example, data from a patient between the year 2000 and 2020 can be stored in the device and, at a certain moment, the operator could be interested, for example, only in the last ten years, or the last three years or the last year, or the first two years, etc.

The set of health parameters according to the present invention (i.e. its composition) can be chosen among a plurality? of possible health parameters by an installer before using the computerized display device. Preferably, the whole can be modified, for example, according to an application of the device; for example, if the device is installed in a driving school, it could be set in such a way that it always and only considers the health parameters relating to the "capabilities" relevant precepts for driving vehicles?.

The set of health parameters according to the present invention (i.e. its composition) can depend on patient health data stored in the computerized device. In particular, can depend on a patient's pathology estimated by the device automatically or quasi-automatically.

The three possibilities? above to determine the composition of the set can be combined with each other.

The mathematical formula according to the present invention can? be chosen by an operator during use of the computerized display device. Preferably, can? be modified.

The mathematical formula according to the present invention can? be checked by an installer before using the computerized display device. Preferably, can? be modified.

The mathematical formula according to the present invention can? depend on the set of health parameters considered, in particular on the composition of the set.

The three possibilities? above relating to the mathematical formula can be combined with each other.

According to the most applications? typical of the present invention, the set of health parameters is consisting of a minimum of three to a maximum of twenty parameters, even more? typically from a minimum of four to a maximum of eight parameters.

Yes ? considered so far the case of simply aggregated health parameters, for example parameters P1 and P2 aggregated, for visualization purposes, to form a ?health state? PA. But can this invention be done? also apply to health parameters organized on multiple levels? levels as shown for example in Fig. 6. Parameters P1-P7 are first-level health parameters, parameters P10 and P20 are second-level health parameters, and parameter P100 ? a third level health parameter. Can you? display the parameter P10 (which can be considered to correspond to the "state of health" PA of the previous example) as an aggregation of the parameters P1 and P2 (all first level), the parameter P20 as an aggregation of the parameters P4 and P5 and P6 ( all first level), the parameter P100 as an aggregation of the parameters P10 and P20 (second level) and P3 and P7 (first level)? the three combination formulas relating to these three aggregations can be the same (a very typical case), but alternatively similar or different. To explain even better, the parameter P1 can? be ?seen?, the P2 parameter can? be ?heard?, the P10 parameter can? be ?capacity? precepts relevant for driving vehicles?, the P20 parameter can? be ?capacity? mental issues relevant to driving vehicles?, and the P100 parameter can? be ?capacity? relevant to driving vehicles? (which include both physical and mental ones); could parameters P3 and P7 be other capabilities? specifications relevant for driving. AND? It is appropriate to keep in mind that the aggregation of more health parameters according to the present invention do not necessarily have to give rise to a ?state of health? (which can also be considered a new ?health parameter?) having a clear meaning and easily expressible in words; In the previous paragraph, examples with clear meanings have been provided just to facilitate understanding.

As can be understood, the method according to the present invention can be successfully and advantageously implemented and incorporated into a computerized appliance equipped with a screen, a processor and memory, such as a desktop or a laptop or a tablet or a smartphone.

In this case, typically, a computer program? stored in memory, and the program is such that the method is implemented when executed by the processor.

This program can be pre-installed in the appliance or installed when required.

Are you? also the possibility? that the device is used only for visualization purposes (thanks in particular to its screen) and that the processing of health data is carried out by another device, for example a ?local server? or a "cloud server". In other words, the computerized device could only perform the HMI functions, i.e. both input and output man-machine interface.
