Abstract

A system for displaying selected information to a person undertaking exercises includes a physical data assessment unit, a physical data gathering unit, and a motion template database. The physical data gathering unit and the motion template database are in communication with the physical data assessment unit. The system further includes an impairment profile generator, an information database including audiovisual information to be displayed to the person according to the impairment profile, and an audiovisual display unit. The information database and the audiovisual display unit are in communication with the impairment profile generator and the impairment profile generator is in communication with the physical data assessment unit. Information such as advertisements is displayed on display to the person where advertisement 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;

a physical data gathering unit;

a motion template database;

the physical data gathering unit and the motion template database being in communication with the physical data assessment unit;

the system further comprising;

an impairment profile generator;

an information database comprising audiovisual information to be displayed to the person according to an impairment profile generated by the impairment profile generator;

an audiovisual display unit;

the information database and the audiovisual display unit being in communication with the impairment profile generator and the impairment profile generator being in communication with the physical data assessment unit,

wherein the physical data gathering unit is configured to calculate an actual posture of the person undertaking exercises for display of a representation of the person undertaking exercises on the audiovisual display unit as a displayed representation,

wherein the physical data assessment unit is configured to form a determined deviation by determining a deviation between a movement of the displayed representation of the person undertaking exercises displayed on the audiovisual display unit and a template representation of a reference person displayed on the audiovisual display unit undergoing a predetermined movement in accordance with the template stored in the motion template database,

wherein the impairment profile generator is configured to update the impairment profile of the person to form an updated profile based on the determined deviation, and

wherein the physical data assessment unit is further configured to select information from the audiovisual information to form selected information for display on the audiovisual display unit based on the updated profile.

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

3. The system according to claim 1, further comprising:

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

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

4. The system according to claim 1, wherein

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

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

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

5. The system of claim 1, wherein the selected information comprises advertisement related to a physical condition of the person undertaking exercises.

6. The system of claim 1, wherein the representation is generated based on tracking of optical sensors on the person undertaking exercises.

7. The system of claim 1, wherein the representation is generated based on signals of at least one motion sensor located on the person undertaking exercises.

8. The system of claim 1, wherein the impairment profile generator updates the impairment profile of the person to include values of blood pressure, mobility and perceived pain of the person undertaking exercises detected by sensors, and wherein the values are used to calculate probabilities that the person needs a wheelchair, a walker and a cane.

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

displaying on a display unit a representation of the person undertaking exercises as a displayed representation and a template representation of a reference person undergoing a predetermined movement in accordance with a template stored in a motion template database;

gathering physical data from the person undertaking exercises including a movement of the displayed representation of the person undertaking exercises displayed on the display unit;

calculating deviation of the physical data from the template stored in the motion template database to form a calculated deviation;

calculating an impairment profile of the person based on the calculated deviation to form a calculated impairment profile;

selecting audiovisual information stored in an audiovisual information database to form selected audiovisual information by applying selection rules based on the calculated impairment profile;

displaying the selected audiovisual information on the display unit.

10. The method according to claim 9, wherein the physical data from the person further comprises at least one of 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.

11. The method according to claim 9, wherein the selected audiovisual information is a target node in a Bayesian network, and wherein 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.

12. The method of claim 9, wherein the selected audiovisual information comprises advertisement related to a physical condition of the person undertaking exercises.

13. The method of claim 9, wherein the representation is generated based on tracking of optical sensors on the person undertaking exercises.

14. The method of claim 9, wherein the representation is generated based on signals of at least one motion sensor located on the person undertaking exercises.

15. The method of claim 9, wherein the impairment profile of the person includes values of blood pressure, mobility and perceived pain of the person undertaking exercises detected by sensors, the method further comprising the act of using the values to calculate probabilities that the person needs a wheelchair, a walker and a cane.
