Abstract

The present invention relates to a system for displaying selected information to a person undertaking exercises comprising a physical data assessment unit (1), a physical data gathering unit (2), a motion template database (4); the physical data gathering unit (2) and the motion template database (4) being in communication with the physical data assessment unit (1); the system further comprises an impairment profile generator (5), an information database (6) comprising audiovisual information to be displayed to the person according to the impairment profile; an audiovisual display unit (7); the information database (6) and the audiovisual display unit are in communication with the impairment profile generator (5) and the impairment profile generator (5) is in communication with the physical data assessment unit (1). According to the impairment profile, information such as advertisements is displayed on display (7) to the person. The invention furthermore relates to a method for displaying selected information to a person undertaking exercises. In preferred embodiments, the selection rules are based on Bayesian inference.

Claims

1. A system for displaying selected information to a person undertaking exercises comprising:

a physical data assessment unit (1);

a physical data gathering unit (2);

a motion template database (4);

the physical data gathering unit (2) and the motion template database (4) being in communication with the physical data assessment unit (1);

the system further comprising;

an impairment profile generator (5);

an information database (6) comprising audiovisual information to be displayed to the person according to the impairment profile;

an audiovisual display unit (7);

the information database (6) and the audiovisual display unit being in communication with the impairment profile generator (5) and the impairment profile generator (5) being in communication with the physical data assessment unit (1).

2. System according to claim 1, wherein the physical data assessment unit (1) is an exercise assessment unit and the physical data gathering unit (2) is a posture assessment unit.

3. System according to claim 1, further comprising:

at least one motion sensor (8) on the person undertaking exercises, the sensor being selected from the group comprising acceleration sensors, inertia sensors and/or gravity sensors;

wherein

the at least one motion sensor (8) transmits its signals to the physical data gathering unit (2); and

the physical data gathering unit (2) calculates a representation of the person'"'"'s posture based on the signals of the at least one motion sensor (8).

4. System according to claim 1, wherein

the physical data gathering unit (2) comprises at least one optical mark (9) on the person undertaking exercises;

the physical data gathering unit (2) comprises an optical tracking system for tracking the at least one optical mark (9); and

the physical data gathering unit (2) calculates a representation of the person'"'"'s posture based on the signals of the optical tracking system.

10. Use of a system according to claim 1 for displaying selected information to a person undertaking exercises.

5. A method for displaying selected information to a person undertaking exercises, comprising the steps of:

a) gathering physical data from the person undertaking exercises;

b) calculating the deviation of the physical data from a template stored in a motion template database (4);

c) calculating an impairment profile of the person;

d) selecting audiovisual information stored in an audiovisual information database (6) by applying selection rules based on the calculated impairment profile;

e) displaying the selected audiovisual information on a display unit (7).

6. Method according to claim 5, wherein the physical data from the person is selected from the group comprising motion data, posture data, electromyographic data, dietary needs, medication used, pulse rate, blood pressure, blood oxygen content, blood sugar content, severity of perspiration, respiratory rate and/or perceived severity of pain and wherein the physical data is used to calculate the impairment profile.

7. Method according to claim 5, wherein a graphical representation of the person'"'"'s posture and an exercise according to a motion template are displayed on an exercise display unit (3).

8. Method according to claim 5, wherein the audiovisual information in step d) is a target node in a Bayesian network, the impairment profile comprises one or more observation nodes in a Bayesian network and the audiovisual information is selected according to its probability in the Bayesian network.

9. Method according to claim 5, wherein a system for displaying selected information to a person undertaking exercises comprising:

a physical data assessment unit (1);

a physical data gathering unit (2);

a motion template database (4);

the physical data gathering unit (2) and the motion template database (4) being in communication with the physical data assessment unit (1);

the system further comprising;

an impairment profile generator (5);

an information database (6) comprising audiovisual information to be displayed to the person according the impairment profile;

an audiovisual display unit (7);

the information database (6) and the audiovisual display unit being in communication with the impairment profile generator (5) and the impairment profile generator (5) being in communication with the physical data assessment unit (1) is used.
