Abstract

To realize complex user wishes or tasks it is suggested in a method for serving user requests with respect to a network of devices to at least search for appropriate and necessary devices for fulfilling the request. Additionally, a necessary sequence of action is generated and derived to bring each of the necessary devices from the current state to a necessary initial state and then from said initial state to a final state. After the generation of said plan, the plan is executed.

Claims

1. Method for serving user requests with respect to a network of devices or the like, in particular for controlling said network of devices, comprising the steps of:

receiving (SI) and/or processing (S1, S2) a user request (UR) thereby generating and/or storing request information data (RID) being representative for said user request (UR),

generating (S3) storing and/or employing device information data (DID) containing information at least of units and/or devices being necessary and/or appropriate with respect to said user request (UR) and/or being available for said man-machine-interface unit and/or containing information of possible states of said units and/or devices,

generating (S4, S5) and/or storing action information data (AID) containing information in accordance with said request information data (RID), said device information data (DID), and/or the like about sequences of actions being appropriate with respect to said user request (UR),

performing (S6) at least one of said sequences of actions in accordance with said action information data (AID), so as to adequately respond to said user request (UR).

2. Method according to claim 1, wherein a complex user request representing a user'"'"'s wish, a desired task, service, device and/or the like or sequence or set thereof is received as said user request (UR), in particular involving several necessariy devices of said network.

3. Method according to any one of the preceding claims, wherein a user utterance is received as an input (SI), in particular in multimodal form.

4. Method according to any one of the preceding claims, wherein speech input (SI) is received as said user utterance, input (SI) or as said user request (UR).

5. Method according any one of the preceding claims, wherein said step of processing (S1, S2) said user request (UR) comprises a step of recognizing (S2) said user request (UR) and in particular a step of speech recognizing.

6. Method according to any one of the preceding claims, wherein an abstract representation is generated for said user request (UR).

7. Method according to any one of the preceding claims, wherein said request information data (RID) is generated so as to contain primary data source information (PDSI), primary data target information (PDTI) and/or primary action information (PAI).

8. Method according to claim 7,

wherein said primary data source information (PDSI) is generated so as to contain information at least indicating possible or potential sources of requested data and/or services,

wherein said primary data target information (PDTI) is generated so as to contain information at least indicating possible or potential targets for potential or derived data and/or services, and/or

wherein said primary action information (PAI) is generated so as to contain information at least indicating possible or potential actions to be performed on requested and/or derived data and/or for said services.

9. Method according to anyone of the preceding claims, wherein said device information data (DID) contain device functionality data (DFD), in particular describing and/or representing possible functionalities of each device, and/or device status data (DSD), in particular describing and/or representing initial, current, and/or final statuses or states of at least said necessary and/or appropriate devices.

10. Method according to anyone of the preceding claims, wherein a dialogue system (30, 31), section, algorithm, or the like is employed, in particular in said steps of deriving (S3), storing and/or employing said device information data (DID), said action information data (AID), and/or the like.

11. Method according to anyone of the preceding claims, wherein a planning module (32), section, algorithm, or the like is employed, in particular as a part of said dialogue system (30, 31), section, algorithm, or the like, and/or in particular containing function models (33-1, . . . , 33-4), state models and/or a reasonning component (34).

12. Method according to anyone of the preceding claims, wherein function models (33-1, . . . , 33-4) are employed, in particular for each device in the network, in global form and/or in the steps of deriving (S3), storing and/or employing device information data (DID), said action information data (AID), and/or the like.

13. Method according to claim 12, wherein each of said function models (33-1, . . . , 33-4) is chosen to contain an external model being descriptive for data being transmitted to and/or from a respective device, device class, or the like.

14. Method according to anyone of the claims 12 or 13, wherein each of said function models (33-1, . . . , 33-4) is chosen to contain an internal model, in particular as a finite state machine, finite state automaton, or the like and/or being descriptive for possible states, of possible transitions between states, of possible actions to initialize said state transitions of said respective device, and/or the like.

15. Method according to any one of the claims 12 to 14, wherein each of said function models (33-1, . . . , 33-4) is chosen to contain a connection model being representative for possible connections between involved devices.

16. Method according to anyone of the preceding claims, wherein in the step of deriving (S3) said device information data (DID) a device search algorithm (DSA) is employed, in particular using said external models.

17. Method according to anyone of the preceding claims, wherein in the step of deriving (S3) said device information data (DID) a state search algorithm (SSA) is employed, in particular using said internal models and/or said state models.

18. Method according to anyone of the preceding claims, wherein in the step of deriving (S3) action information data (AID) an action search algorithm (ASA) is employed, in particular using said internal models and/or said reasoning component (34).

19. Method according to anyone of the preceding claims, wherein in the step of performing one of the sequences of action an action performing algorithm (APA) is employed.

20. Network of devices, man-machine-interface unit or the like or system for operating the same which is capable of performing and/or realizing the method to any one of the preceding claims 1 to 19 and/or the steps thereof.

21. Computer program product, comprising computer program means adapted to perform and/or to realize the method according to any one of the preceding claims 1 to 19 and/or the steps thereof, when it is executed on a computer, a digital processing means and/or the like.
