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

1. A motion detection system, comprising:

a sensor arranged to;

detect a movement of a moveable object configured and dimensioned for being held by a user'"'"'s hand, and

sense aspects of a relationship between the moveable object and at least one additional moveable object configured and dimensioned for being held by the user'"'"'s hand, wherein the moveable object and the at least one additional moveable object are rotable about an axis perpendicular to the users hand; and

a control device positioned on or within the moveable object, the control device arranged to;

receive movement data representative of the detected movement;

formulate a movement pattern of the moveable object based on the received movement data;

compare the formulated movement pattern with a plurality of predetermined movement patterns;

determine which of said plurality of predetermined movement patterns matches the formulated movement pattern;

determine a coherence parameter representative of the coherence between the formulated movement pattern and the matching one of the plurality of predetermined movement patterns; and

control a feedback device, providing feedback to the user on the basis of the determined coherence parameter, said control device storing said plurality of predetermined movement patterns, wherein said predetermined movement patterns comprising;

relaxation patterns that can be performed with the moveable objects in order for the user to achieve a state of relaxation or concentration.

2. The system according to claim 1, wherein the sensor is one of:

an acceleration sensor, a positional sensor, a speed sensor and a gyroscopic sensor.

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

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

5. The system according to claim 1, wherein the sensor is incorporated within the object.

6. The system according to claim 1, wherein the control device comprises:

an electronic memory for storing the predetermined movement patterns.

7. The system according to claim 1, wherein the feedback device is arranged to provide feedback in the form of at least one of:

a light, a sound, a vibration, a temperature and a combination thereof.

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

communication means for wirelessly communicating feedback data to the feedback device.

9. The system according to claim. 1, comprising:

a further sensor arranged to;

measure physical data relating to the user, said physical data representing 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 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.

10. The system according to claim 1, wherein the sensor is further arranged to:

collect relationship data relating to said moveable object and said at least one additional moveable object, said relationship data containing data about at least one of a distance and a relative movement pattern between the moveable object and said at least one additional moveable object, wherein the control device is further arranged to;

control the feedback device on the basis of the relationship data.

11. The system according to claim 1, wherein said movable objects 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 comprises the sensor and the feedback device.

12. The system according to claim 1, wherein the feedback device comprises a number of light sources arranged to emit light.

13. The system according to claim 1, wherein said movable objects comprise a number of light sources arranged to emit light.

14. The system according to claim 11, wherein said at least one of said movable objects is provided with an electrical power source.

15. The system according to claim 11, wherein at least one of said movable objects comprises actuation means arranged to act upon the at least one further movable object under control of the control device.

16. The system according to claim 11, wherein the sensor, the control device and the feedback device operate in real-time.

17. The system according to claim 11, wherein the feedback device comprises a vibration device.

18. The system according to claim 12, wherein both moveable objects comprise a vibration device.

19. The system according to claim 14, wherein said electrical power source is a rechargeable electrical power source.

20. The system according to claim 15, wherein said actuation means comprises at least one of a gyroscopic and magnetic device.
