Abstract

A method and apparatus for automated play tracking sports play. A coordinating device receives first messages from player wireless sensors node carried by the players and a second message from a ball wireless sensor node carried by the ball. From these messages, the locations of the players and the ball are determined. From the relative locations of the players and the ball it is determined, which, if any, of the plurality of players possess the ball and a description of play is generated automatically. This description may be broadcast to subscribers via a network.

Claims

1. A method for automated play tracking in a sport played by a plurality of players comprising:

for each player of the plurality of players;

receiving a first message from a player wireless sensor node carried by the player;

receiving a second message from a ball wireless sensor node carried by a ball;

determining, from the first and second messages, the locations of the plurality of players and the ball;

determining, from the locations of the plurality of players and the ball, which, if any, of the plurality of players possess the ball; and

generating a third message that identifies which player, if any, of the plurality of players possess the ball.

2. A method in accordance with claim 1, further comprising storing the third message in a database.

3. A method in accordance with claim 1, further comprising transmitting the third message over a network to a subscriber device.

4. A method in accordance with claim 3, wherein the sport is played in a defined area of play, the method further comprising transmitting locations of the defined area of play over a network to the subscriber device.

5. A method in accordance with claim 1, further comprising generating a graphical visualization of play dependent upon the third message.

6. A method in accordance with claim 5, further comprising assigning avatars for players in the graphical visualization of play.

7. A method in accordance with claim 1, wherein the first message comprises an identifier of the player carrying the wireless sensor node, the location of the player in an area of play and a time stamp, the location of the player being determined by the player wireless sensor node.

8. A method in accordance with claim 7, wherein the location of the player is determined relative to nodes at fixed positions.

9. A method in accordance with claim 1, wherein the second message comprises the location of the ball and a time stamp, the location of the ball in an area of play, being determined by the ball wireless sensor node.

10. A method in accordance with claim 9, wherein the location of the ball is determined relative to nodes at one or more fixed scoring positions.

11. A method in accordance with claim 1, wherein the player wireless sensor nodes and the ball wireless sensor node use at least one communication protocol selected from a ZigBee communication protocol and WiFi protocol.

12. A method in accordance with claim 1, further comprising determining an order of play from successive locations of the plurality of players and the ball.

13. A method in accordance with claim 1, wherein the third message comprises a text message generated automatically dependent upon the locations of the plurality of players and the ball.

14. A method in accordance with claim 1, further comprising retrieving historical information from a database, wherein the third message includes historical information related to the play.

15. A system for automated play tracking in a sport played by a plurality of players comprising:

a plurality of fixed nodes positioned in an area of play;

a plurality of first sensor nodes, each carried by a player of the plurality of players and operable to read identifier information from at least one fixed node in proximity to the player;

a second sensor node carried by a ball and operable to read identifier information from at least one fixed node in proximity to the ball; and

a controller operable to receive information dependent upon the identifier information from the plurality of first sensor nodes and the second sensor node and further operable to produce play information comprising the locations of the plurality of players and the ball.

16. A system in accordance with claim 15, wherein the play information further comprises which, if any, of the plurality of players possesses the ball.

17. A system in accordance with claim 15, wherein the play information further comprises the players'"'"' identities.

18. A system in accordance with claim 15, further comprising:

a translator operable to produce a message containing the play information; and

a subscriber manager, operable to disseminate the play information to subscribers via a network.

19. A system in accordance with claim 15, wherein a fixed node of the plurality of fixed nodes comprises an RFID tag.

20. A system in accordance with claim 19, wherein the plurality of first sensor nodes and the second sensor node comprise RFID tag readers.

21. A system in accordance with claim 15, wherein a fixed node of the plurality of fixed nodes comprises a wireless sensor node.

22. A system in accordance with claim 15, wherein the plurality of first sensor nodes and the second sensor node comprise wireless sensor nodes.

23. A system in accordance with claim 15, wherein the controller comprises a receiver in the locality of the area of play and a processing device linked to the receiver via a data network 24. A method for receiving a play-by-play description of a sporting event played by a plurality of players using a ball, the method comprising:

downloading a description of an area of play from a subscriber manager;

downloading, from the subscriber manager, the locations and identifiers of a plurality of first sensor nodes, each first sensor node carried by a player of the plurality of players and in communication with the network server;

downloading the location of a second sensor node carried by the ball and in communication with the subscriber manager via a controller;

assigning an avatar to each identifier; and

generating a graphical visualization of the area of play showing avatars at the locations of the first sensor nodes and showing the location of the ball.

24. A method for automated play tracking in a sport played by a plurality of players comprising:

for each player of the plurality of players;

receiving a first message from a player wireless sensor node carried by the player;

receiving a second message from a ball wireless sensor node carried by a ball;

determining, from the first and second messages, the locations of the plurality of players and the ball;

determining, from the locations of the plurality of players and the ball, which, if any, of the plurality of players has achieved a score;

generating a third message that identifies which player, if any, of the plurality of players has achieved a score;

transmitting the third message to a subscriber device; and

the subscriber device inputting information derived from the third message to an application executed on the subscriber device.

25. A method in accordance with claim 24, wherein the application comprises a gaming application.
