Abstract

The invention relates to a system for detecting a user-dependent state of a sports object, comprising a detection device (101) for detecting a plurality of positions of the sports object, and a determination device (103) for determining the state of the sports object based on the plurality of positions detected.

Claims

1. A system for detecting a user-dependent state of a sports object, comprising:

a detection device comprising at least one of a detection signal transmitter and a detection signal receiver and configured to detect an actual position of the sports object;

a determination device comprising a data receiver and a processor configured to determine a desired position of the sports object in a manner dependent on the actual position of the sports object; and

an indication device configured to indicate a detected plurality of positions of the sports object and to indicate information relating to the desired position if the actual position differs from the desired position,

wherein the determination device is configured to determine a predetermined position of the sports object as the desired position, and wherein the predetermined position is predefined with an aid of a rule.

2. The system of claim 1, wherein the user is equipped with a transmitter configured to transmit a signal that is received by the detection device.

3. The system of claim 1 , wherein the state of the sports object is in at least one of:

(i) residence duration of the sports object at a user, (ii) velocity of the sports object, (iii) momentum of the sports object, (iv) direction of movement of the sports object, and (v) acceleration of the sports object.

4. The system of claim 1, wherein the sports object comprises a transmitter configured to emit a position signal and wherein the detection signal receiver is configured to receive the emitted position signal to determine the actual position of the sports object.

5. The system of claim 1, wherein the detection signal transmitter is configured to transmit a signal that reflects off of the sports object and wherein the detection signal receiver is configured to receive the reflected signal, and in response, to determine the actual position of the sports object based upon the reflected reflection signal.

6. The system of claim 1, wherein the determination device is configured to determine a first instant of a user receiving the sports object and a second instant of the user releasing the sports object to determine a residence duration of the sports object with the user as the desired position of the sports object.

7. The system of claim 6, wherein the determination device is configured to determine a third instant of the user transferring the sports object between the first instant and the second instant, to determine a first sub-residence duration between the first instant and the third instant and a second sub-residence duration between the third instant and the second instant.

8. The system of claim 1, wherein the determination device is configured to determine an instant of an acceptance of the sports object by detection of a negative acceleration of the sports object with an aid of a temporal profile of the plurality of positions of the sports object.

9. The system of claim 1, wherein the determination device is configured to determine an instant of a release of the sports object by detection of a positive acceleration of the sports object with the aid of a temporal profile of the actual position of the sports object.

10. The system of claim 1 further comprises a sports object provider for dispensing the sports object.

11. The system of claim 1 further comprises a sports object catcher for catching the sports object after a sports object is released by the user.

12. The system as claimed in claim 11, wherein the sports object catcher is at least one of a ball goal and a sensor wall.

13. The system of claim 1, wherein the detection device is configured to store the detected plurality of positions.

14. The system of claim 1, wherein the indication device is configured to project a desired position onto a playing area.

15. The system claim 1, wherein the determination device is configured to compare the actual position with a desired position.

17. The system of claim 3, wherein the velocity is at least one of translational velocity and rotational velocity, wherein the momentum is at least one of angular momentum and translational momentum, and the acceleration is at least one of positive acceleration and negative acceleration.

18. The system of claim 4, wherein the position signal is a global positioning signal.

19. The system of claim 5, wherein the detection signal transmitter is at least one of radar signal and a laser signal.

16. A method for detecting a user-dependent state of a sports object, comprising:

(i) detecting an actual position of the sports object by a detector comprising at least one of transmitting a detection signal and receiving a detection signal;

(ii) determining a desired position of the sports object in a manner dependent on the actual position of the sports object by a determination device configured to receiving data from the detector and processing the received data;

(iii) indicating a detected plurality of positions of the sports object; and

(iv) indicating information relating to the desired position if the actual position differs from the desired position,

wherein the determination device is configured to determine a predetermined position of the sports object as the desired position, and wherein the predetermined position is predefined with an aid of a rule.
