Abstract

The invention pertains to a portable device comprising a housing, a display, a storage medium, at least one acceleration sensor, means for calculating an activity parameter based on the signal generated by the acceleration sensor, storing the calculated parameter in the storage medium, and showing the same in the display. The said parameter is the Physical Activity Index (PAI) or a derivative thereof.

Claims

1. A portable device comprising:

a housing;

a display;

a storage medium;

at least one acceleration sensor; and

means arranged for calculating an activity parameter based on a signal generated by the at least one acceleration sensor, storing the calculated parameter in the storage medium, and showing the same in the display, wherein said parameter is the Physical Activity Index (PAI) or a derivative thereof, which is solely calculated by multiplying an average of the absolute values of a signal or samples of a signal of the at least one acceleration sensor with at least one constant, which at least one constant is independent of personal data of a user of the portable device, whereby the at least one constant is a universal metric that is not related to age, weight, or gender, the portable device being immediately operable after being powered ON such that the user that uses the portable device is not required to calibrate the portable device nor input his personal data to allow the portable device to accurately function.

2. The portable device according to claim 1, wherein the said average is at least multiplied by a calibration factor which depends on the sensor.

3. The portable device according to claim 1, wherein the device further comprises a rectifier for rectifying the signal generated by the acceleration sensor and a capacitor which is charged by the rectified signal.

4. The portable device according to claim 1, wherein the device comprises an input/output connector which enables transfer of at least some information stored on the storage medium to a computer connectable to at least one of an electronic database and an electronic algorithm.

5. The portable device according to claim 1, wherein the device comprises a clip for attaching the device to an item of clothing of a wearer such that rotation of the device with respect to the wearer is substantially avoided and wherein the sensor is adapted to be positioned at an angle in a range from 30 to 60 degrees to horizontal when the wearer is standing upright.

12. A plurality of portable devices according to claim 1, wherein each of the plurality of portable devices wherein the means arranged for calculating the activity parameter includes said at least one constant such that for a plurality of different individuals, the calculated parameter will solely be calculated independent of personal data for the plurality of different individuals such that the individuals need not provide personal data for display of the activity parameter on the portable device associated with the individual.

6. A method of generating instructions or advice on how to increase physical activity and tailored to at least one of objective needs and preferences of an individual, which method comprises:

electronically obtaining a parameter concerning that individual using a portable device containing an acceleration sensor,

wherein the said parameter is the Physical Activity Index (PAI) or a derivative thereof, which is solely calculated by multiplying an average of the absolute values of a signal or samples of a signal of the acceleration sensor with at least one constant, which constant is independent of personal data of a user of the portable device;

electronically obtaining personal information of the individual for setting a personal goal of the individual;

selecting, based on the obtained Physical Activity Index and the personal goal, one or more instructions or advice components from a database to reach said personal goal;

accessing said instructions or advice components for use by the individual, whereby the at least one constant is a universal metric that is not related to age, weight, or gender, the portable device being immediately operable after being powered ON such that the user that uses the portable device is not required to calibrate the portable device nor input his personal data to allow the portable device to accurately function.

7. The method according to claim 6, and further comprising:

uploading the said parameter to a remote server system, which performs the step of selecting; and

downloading from the remote computer the selected one or more instructions or advice components or a processed version thereof.

8. The method according to claim 7, and further comprising uploading an identification code to the remote server system.

9. A computer program product code means stored in a computer readable medium for performing the following steps when said program product is run on a computer:

electronically obtaining a parameter concerning that individual; and

selecting, based on the said parameter, one or more instructions or advice components from a database, wherein the said parameter is the Physical Activity Index (PAI) or a derivative thereof, which is solely calculated by multiplying an average of the absolute values of a signal or samples of a signal of an acceleration sensor with at least one constant, which constant is independent of personal data of a user of an portable device, whereby the at least one constant is a universal metric that is not related to age, weight, or gender, the portable device being immediately operable after being powered ON such that the user that uses the portable device is not required to calibrate the portable device nor input his personal data to allow the portable device to accurately function.

10. The computer program product code means of claim 9, and further comprising:

uploading the said parameter to a remote server system, which performs the step of selecting; and

downloading from the remote computer the selected one or more instructions or advice components or a processed version thereof.

11. The computer program product code means of claim 10, and further comprising uploading an identification code to the remote server system.
