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 for detecting a plurality of positions of the sports object; and

a determination device for determining the state of the sports object based upon the detected plurality of positions.

2. The system of claim 1, wherein the sports object is least one of a ball and a puck, and wherein the user is a sportsperson.

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 is designed to emit a position signal and wherein the detection device is designed to receive the position signal in order to determine the plurality of positions.

5. The system of claim 1, wherein the detection device is designed to receive a reflection signal reflected at the sports object and to determine a plurality of positions the reflected reflection signal.

6. The system of claim 5, wherein the detection device is designed to emit a transmission signal in order to generate the reflection signal.

7. The system of claim 1, wherein the determination device is designed to determine a first instant of an acceptance of the sports object by the user and a second instant of a release of the sports object by the user, in order to determine a residence duration of the sports object at the user as the user-dependent state of the sports object.

8. The system of claim 7, wherein the determination device is designed to determine a third instant of a transfer of the sports object by the user between the first instant and the second instant, in order 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.

9. The system of claim 1, wherein the determination device is designed 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.

10. The system of claim 1, wherein the determination device is designed 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 plurality of positions of the sports object.

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

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

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

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

15. The system of claim 1 further comprises an indication device capable of at least one of indicating the detected plurality of positions and projecting a projection region onto a playing area.

16. The system claim 1, wherein the determination device is designed to compare the user-dependent state with a reference state to assess the user dependent state.

18. 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.

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

20. The system of claim 5, wherein the reflection signal is at least one of radar signal and a laser signal.

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

detecting a plurality of positions of the sports object; and

determining the state of the sports object based upon the detected plurality of positions.
