Abstract

A motion detection system (100) comprises a sensor (106) arranged to detect a movement pattern of a movement occasioned by a user, and a control device (108) arranged to receive movement data representative of the detected movement pattern. The control device (108) is further arranged to compare the detected movement pattern data with movement pattern data representative of a predetermined movement pattern and to determine a coherence parameter representative of the coherence between the detected and the predetermined movement pattern. The control device (108) controls a feedback device (110) for providing feedback to the user on the basis of the determined coherence parameter.

Claims

a sensor (106) arranged to detect a movement pattern of a movement occasioned by a user;

a control device (108) arranged to receive movement data representative of the detected movement pattern, characterized in that, the control device (108) is further arranged to compare the detected movement pattern data with movement pattern data representative of a predetermined movement pattern and to determine a coherence parameter representative of the coherence between the detected and the predetermined movement pattern and to control a feedback device (110) for providing feedback to the user on the basis of the determined coherence parameter.

2. System according to claim 1, wherein the sensor (106) is one of an acceleration sensor, a positional sensor, a speed sensor and a gyroscopic sensor.

3. System according to claim 2, wherein the sensor (106) is an acceleration sensor and detects acceleration of the movement occasioned by the user in at least one direction.

4. System according to claim 2, wherein the sensor (106) is an acceleration sensor and detects acceleration of the movement occasioned by the user in at least two directions and wherein the control device (108) is arranged to determine an average acceleration value averaging the acceleration in said directions.

5. System according to claim 2, wherein the sensor (106) detects the movement pattern of a moveable object (102) carried by the user.

6. System according to claim 5, wherein the sensor (106) is incorporated with the object (102).

7. System according to claim 5, wherein the control device (108) comprises an electronic memory for storing predetermined movement pattern data.

8. System according to claim 5, wherein the feedback device (110) is arranged to provide feedback to the user in the form of at least one of light, sound, vibration, temperature or any combination thereof.

9. System according to claim 5, wherein the feedback device (110) is incorporated with the object (102).

10. System according to claim 5, wherein the feedback device (110) is located externally from the object (102).

11. System according to claim 5, further comprising communication means (124) for wireless communication of feedback data to the feedback device (110).

12. System according to claim 5, comprising a further sensor arranged to measure physical data relating to the user, in particular the further sensor is arranged to measure at least one of a heart rhythm of the user, a body temperature of the user, a blood pressure of the user and a conductive skin impedance of the user, and wherein the control device (108) is further arranged to receive and analyze the measured physical data and to supply feedback data based on the measured physical data to the feedback device (110).

13. System according to claim 5, wherein the system (100) further comprises at least one additional moveable object (104).

14. System according to claim 13, wherein the sensor (106) is further arranged to collect relationship data relating to said objects (102, 104), said relationship data containing data about at least one of a distance and a relative movement pattern between the objects (102, 104), wherein the control device (108) is further arranged control the feedback device (110) on the basis of the relationship data.

15. System according to claim 13, wherein said objects (102, 104) are spherical and can be held in a palm of the user'"'"'s hand and moved simultaneously by the user, wherein at least one of the objects (102, 104) comprises the sensor (106) to detect a movement pattern and comprises the feedback device (110).

16. System according to claim 15, wherein the feedback device (110) comprises a number of light sources (122), in particular LED'"'"'s, which are arranged to emit light, and/or comprises a vibration device (112).
