The present invention relates to the health and the physical activity of a user, particularly to a portable device, method and program product for generating a parameter related to the physical activity of a user.
Nowadays, many people are aware of the importance of healthy nutrition and sufficient physical activity.
In this regard, portable devices are known which are able to monitor the physical activity of a user, generating information representative of the performed physical activity.
Examples of such portable devices comprise a sensor (e.g. an accelerometer) configured to collect information representative of the movement of the user and a processing unit configured to generate and provide the user with information representative of the amount of the physical activity performed by the user.
However, nowadays, such portable devices and the information they are able to provide the user with, are no longer sufficient or satisfactory.
Therefore, making available portable devices able to provide the user with more information about the performed physical activity in order to stimulate the physical activity of a user in a more precise and reliable manner is strongly needed.
It is the object of the present invention to provide a portable device which allows to overcome the drawbacks of the prior art mentioned above, in particular which can provide the user with more precise and reliable parameters related to the physical activity performed by the user.
Such an object is achieved by a portable device according to claim 1.
The present invention further relates to a method for generating a parameter related to the physical activity of a user.
The present invention also relates to a program product loadable in a memory unit of an electronic calculator (e.g. an electronic device, such as a smartphone, a tablet, a PDA, a smartwatch and so on), the program product being executed by a data processing unit of the electronic calculator.
Further features and advantages of the portable device, the method and program product according to the present invention will become more apparent from the following description of preferred embodiments thereof, given by way of a non-limiting example, with reference to the accompanying drawings, in which:
Similar or equivalent elements in the figures are indicated with the same reference numerals and/or alphanumeric references.
With reference to the embodiment of
It should be observed that in the embodiment of
The device of
The device 1 comprises at least one sensor 2 to measure information representative of the movement of the user.
For the purposes of the present invention, “information representative of the movement of the user” means information related to the movement of the user's body during the physical activity performed while training or during normal everyday life, such as for example acceleration, speed and so on.
Such as least one sensor 2 is configured to generate, on the basis of such information, a plurality of values of physical activity data.
In greater detail, the physical activity data generated on the basis of such information relate to the intensity of the physical activity performed by the user.
With this regard, it should be noted that such intensity of the physical activity may be expressed by the physiological measure expressing the energy cost of physical activities called MET (i.e. METabolic equivalent).

In addition, the data processing unit 3 is further configured to generate a physical activity rate parameter in a first reference time instant t0 on the basis of a portion of values of the plurality of values of physical activity data generated by said at least one sensor 2 in a set period of time preceding the first reference time instant to.
As will be explained below, “first reference time instant t0” means the time instant in which the data processing unit 3 generates the physical activity rate parameter.
The set period of time preceding the first reference time instant t0 may be set as any period of time preceding the first reference time instant t0, e.g. 1 hour before the first reference time instant t0, half hour before the first reference time instant t0, 10 minutes before the first reference time instant t0, one minute before the first reference time instant t0, and so on.
According to a further embodiment, the set period of time preceding the first reference time instant t0 is a period of time comprised between a time instant of beginning of physical activity and the first reference time instant t0.
“Time instant of beginning of physical activity” means the time instant in which said at least one sensor 2 generates a set number of values of physical activity data in a set period of beginning of physical activity. By way of example, the set number values of physical activity data may be 5, 6, 7 and so on, generated in a set period of beginning of physical activity equal to three minutes.
It is further worth noting that the time instant of beginning of physical activity may be stated by the user according to his or her habits. For example, a user who wakes up every morning at 7 o'clock can set that time as time instant of beginning of physical activity.
On a general level, the fact of generating a physical activity rate parameter in a first reference time instant t0 on the basis of a portion of values of physical activity data generated by said at least one sensor 2 in a set period of time preceding the first reference time instant t0 advantageously allows to obtain a physical activity rate parameter representative of the physical activity of the user in a set period of time preceding the time instant in which such a parameter is generated (the first reference time instant t0), such as the last hour, the last half hour, the last ten minutes, the entire period during which the physical activity rate was detected by the user.
In such a manner, it is thus possible to provide the user, in any time instant, with an updated parameter related to the physical activity rate performed by the user herself/himself, who can thus obtain relevant information in more accurate and reliable manner.
Turning again to the embodiment of
In particular, the memory unit 4 is configured to store the plurality of values of physical activity data generated by said at least one sensor 2 and obviously also the physical activity rate parameter generated by the data processing unit 3.
In addition, the memory unit 4 is configured to store one or more client software applications to allow the user to enjoy one or more digital services provided by one or more client software applications directly through the device 1.
Furthermore, it is also confirmed that “client software application” means client software application of the standard type available on the market for electronic calculators and/or portable electronic devices, such as a personal computer, a notebook, a mobile phone (e.g. a smartphone), a tablet, a digital audio/video file reader (e.g. a MP3 reader), and so on.
The device 1 further comprises a display 5, operatively connected to the data processing unit 3, configured to display to the user at least one of the following: the plurality of values of physical activity data generated by the sensor 2 and the activity index parameter generated by the data processing unit 3.
The device 1 may also comprise a control panel, i.e. a keyboard or a graphical user interface, (not shown in
The device 1 may also comprise a data communication module 6 configured to communicate with other electronic devices and electronic calculators (e.g. a server computer), also arranged in a remote location, via a data communication channel in a wired or wireless mode.
With reference now also to
A graphic element may be representative of the plurality of values of physical activity data generated by said at least one sensor 2, of the physical activity rate parameter generated by the data processing unit 3, of a combination thereof, or of other information related in all cases to the physical activity performed by the user.
With reference in particular to
In greater detail, the data processing unit 3 is configured to compare the generated physical activity rate parameter with a set plurality of threshold values of the generated physical activity rate parameter. The set plurality of threshold values is adapted to define a plurality of value intervals of said physical activity rate parameter, each of such intervals being representative of a qualitative index of the represented physical activity rate parameter.
With particular reference to
The data processing unit 3 is configured to position the indicator 32, relatively to the dashboard 31, on the basis of the comparison of the generated physical activity rate parameter with the set plurality of threshold values of the generated physical activity rate parameter, e.g. on hourly basis, as will be explained below.
In the embodiment of
If the generated physical activity rate parameter is comprised between the first threshold value S1 and the second threshold value S2, the indicator 32 will be positioned at the respective value within the second interval RG2. From the quality point of view, the indicator 32 indicates to the user that the intensity of the physical activity is “medium” or “active”, comparable to that of an active, but not sporty, user.
If the generated physical activity rate parameter is above the second threshold value S2, the indicator 32 will be positioned at the respective value within the third interval RG3. From the quality point of view, the indicator 32 indicates to the user that the intensity of the physical activity is “high” or “sporty”, i.e. comparable to that of a sporty user.
From a graphic point of view, in order to qualitatively facilitate the reading of the first graphic element 30 by the user, the dashboard 31 may be, for example, a red-yellow-green color scale passing from the first interval RG1 to the third interval RG3 and/or displaying alphanumeric writing (not shown in
With reference now to
With this regard, the second graphic element 40 comprises a reference bar 41, whose length L is representative of the target determined by the user in a set period of time (e.g. daily target). It is worth noting that such target is previously generated by the data processing unit 3 on the basis of user physical activity data generated by said at least one sensor 2 in a previously set period of time, e.g. during the previous two weeks.
The data processing unit 3 is configured to display on the reference bar 41 a first progressive bar 42 representative of the amount of physical activity data values generated by said at least one sensor 2 in a set current time instant tc (t0). This occurs, for example, by illuminating and/or coloring with a first color (e.g. white) a portion of the reference bar 41 corresponding to the first progressive bar 42. In an embodiment, shown in
Furthermore, the data processing unit 3 is configured to display on the reference bar 41 a second progressive bar 43 representative of the amount of values of physical activity data generated by said at least one sensor 2 at the same current time instant tc (t0) of a preceding set period of time (e.g. the last two weeks). This occurs, for example, by illuminating and/or coloring with a second color (e.g. grey) a portion of the reference bar 41 corresponding to the second progressive bar 42. In an embodiment, shown in
In the example of
In the example of
In other words, the second number of bars of said plurality 41 represents an average amount of physical activity data generated by the user in the same current time instant, but generated in a previous set period of time (e.g. in the last two weeks). For example, if the current time instant is a specific time (10 o'clock), the second number of bars of said plurality 41 represents an average amount of physical activity data generated in the same specific time period of the past two weeks.
This allows the user to view on the portable device 1 the generated physical activity data in the current instant not only with respect to the set target but also with respect to the physical activity data generated in a previous set period of time. This allows the user to determine whether he or she is improving the previous performance in the current time instant, regardless of whether the set target is being reached or not.
Furthermore the main advantage for the user is that the value of the second progressive bar 43 represents a “reference” to be followed to attempt to achieve and reach the target of “amount of values of physical activity data” at the end of the day (which is represented by the total length of the reference bar 41). In this manner, the user can predict whether the target will be reached or not and in all cases whether it is coherent with what was previously performed in view of reaching the target. If the user is further ahead (first progressive bar 42 greater than the second progressive bar 43) the user knows that he or she is improving the previous performance with respect to the average of the previous period.
It should be noted that in an embodiment, not shown in the figures, the data processing unit 3 is configured to show a first numeric data representative of the physical activity data generated by said at least one sensor 2 and a second numeric data representative of the target determined by the user, close to the second graphic element 40.
With reference now to
In greater detail, such a sheet comprises a first portion 51, in which an image representative of the physical exercise to be performed can be inserted, and a second portion 52, in which an alphanumerical descriptive text of the exercise and of the physical activity data to be obtained by the user can be inserted.
With reference now to
In greater detail, the fourth graphic element is a time diagram which shows the time on the abscissa axis and the physical activity rate parameter on the ordinate axis. The amount of physical activity data generated over time can be placed within one of the physical activity rate intervals RG1, RG2, RG3 shown diagrammatically also in
Again with reference to
Furthermore, the data processing unit 3 is configured to generate a second portion of further graphic elements 62, each of which is representative of a physical exercise of physical activity which can be performed by the user, together with the progressive value of generated physical activity data and with the incremental value of the time of performance of the physical exercise or physical activity.
With reference to
Turning back to the data processing unit 3 of the device 1 and to the parameter generation mode of the physical activity rate parameter, it is worth noting that in an embodiment, such a data processing unit 3 is configured to execute the following operations.
The data process unit 3 is configured to calculate a target value of physical activity data to be generated (accumulated) by the user, at each set calculation time interval (e.g. every hour).
With respect to the actual amount of physical activity data generated with respect to the target value, the data processing unit 3 is configured to determine the plurality of intervals described above with particular reference to
With this regard, the data processing unit 3 is configured to calculate the plurality of threshold values (e.g. the first threshold value S1 and the second threshold value S2) as follows.
Assuming a set number of hours of physical activity during a day, e.g. 12 hours, on the basis of experimental data, a set number of physical activity data, e.g. 1200, that a user with sporty profile can generate (accumulate) in the set number of hours of physical activity (12), is also available.
The data processing unit 3 is configured to divide the set number of physical activity data by the set number of hours of physical activity (1200/12=100) and subsequently divide such a result by the number of intervals of such a plurality of intervals of values of said physical activity rate parameter (three in the previously described example: first interval RG1, second interval RG2, third interval RG3). In this manner, the values of three intervals can be obtained: first interval RG1—from 0 to 33.3; second interval RG2—from 33.3 to 66.6; third interval RG3—from 66.6 to 99.9. In this case, the first threshold value S1 is 33.3, while the second threshold value S2 is 66.6. It is worth noting that the indicator 32 is positioned on the dashboard 31, for example, on an hourly basis.
In order to determine the number of hours of physical activity of the user, the data processing unit 3 is configured to set a time instant of beginning of physical activity by the user and an time instant of ending of physical activity by the user.
With this regard, in one embodiment, the time instant of beginning of physical activity is the time instant in which said at least one sensor 2 generates a set value of physical activity data (e.g. 5) in a set minimum period of time (e.g. in a period of time shorter than three minutes). The time instant of ending of physical activity is the time instant in which said at least one sensor 2 does not generate a set value of physical activity data (e.g. 5) in a set minimum period of time (e.g. three minutes).
According to a further embodiment, the time instant of beginning of physical activity and the time instant of ending of physical activity are obtained from the average of the time instants of beginning of physical activity and of the time instants of ending of physical activity, determined in an set sample time period (e.g. over the past two weeks).
With reference now to

Furthermore, the method 200 comprises a step of generating 202, by the sensor 2, on the basis of such information, a plurality of values of physical activity data.
The physical activity data are generated on the basis of such information, related to the intensity of physical activity performed by the user.
It should be noted that such an intensity of the physical activity may be expressed by the physiological measure expressing the energy cost of physical activities called MET (i.e. METabolic equivalent).
Turning back to
Furthermore, the step of generating 203 comprises a step of generating 204, by the data processing unit 3, the activity rate parameter in a first reference time instant t0 on the basis of a portion of values of the plurality of values of physical activity data generated by said at least one sensor 2 in a set period of time preceding the first reference time instant t0.
The step of generating 203 further comprises a step of setting 205 such a set period of time preceding the first reference time instant t0 as any period of time preceding the first reference time instant t0, e.g. 1 hour before the first reference time instant t0, half hour before the first reference time instant t0, 10 minutes before the first reference time instant t0, 1 minute before the first reference time instant t0, and so on.
The method 200 ends with a symbolic step of ending ED.
According to a further embodiment, not shown in the figure, the step of setting 205 comprises a step of setting, by the data processing unit 3, the set period of time preceding the first reference time instant t0 as a period of time comprised between a time instant of beginning of physical activity (defined above) and the first reference time instant t0.

The set plurality of threshold values was defined above with particular reference to the embodiment of
According to an embodiment, the method 200 subsequently comprises the step of placing, by the data processing unit 3, an indicator 32, relative to a dashboard 31 of the first graphic element 30, on the basis of the comparison of the generated physical activity rate parameter with the established plurality of threshold values of the generated physical activity rate parameter.
According to an embodiment, the method 200 further comprises a step of generating, by the data processing unit 3, a second graphic element 40 representative of the amount of values of physical activity data generated by said at least one sensor 2. The second graphic element 40 is described above.
In particular, the step of generating a second graphic element 40 comprises the steps of:
According to a further embodiment, not shown in the figures, the method 200 comprises a step of generating, by the data processing unit 3, a third graphic element 50 representative of an informative sheet adapted to suggest to the user the physical exercise or how to improve the lifestyle. Such a sheet was described above.
