Abstract

The invention relates to a communication system having a display unit (2) and a virtual being (3) that can be visually represented on the display unit (2) and that is designed for communication by means of natural speech with a natural person, wherein at least one interaction symbol (6, 7) that can be represented on the display unit (2) and by means of which the natural speech dialog between the virtual being (3) and the natural person is supported such that an achieved dialog state can be indicated and/or additional information depending on the dialog state achieved and/or information can be redundantly invoked. The invention further relates to a method for representing information of a communication between a virtual being and a natural person.

Claims

1. A communication system comprising:

a display unit and a virtual being that can be visually represented on the display unit and that is designed for communication by means of natural speech dialog with a natural person wherein

the display unit conducts the natural speech dialog between the virtual being and the natural person using a transmitting unit to transmit acoustical signals and a receiving unit to receive acoustical signals, the acoustical signals including speech signals,

at least one interaction symbol, which can be visually represented on the display unit and which assists the natural speech dialog between the virtual being and the natural person in such a way that an achieved dialog state can be displayed; and

/or additional information and/or information can be retrieved in a redundant manner as a function of the achieved dialog state,

wherein at least one interaction symbol displayed on the display unit dynamically changes according to a temporal progression and content of a dialog between the virtual being and the natural person.

2. The communication system according to claim 1 wherein the interaction symbol is displayed on the display unit as a function of a dialog situation after an achieved dialog state between the virtual being and the natural person.

3. The communication system according to claim 1 wherein at least one interaction symbol is statically displayed during its entire time duration of the display.

4. The communication system according to claim 1 wherein at least one interaction symbol is dynamically displayed at least temporarily during its entire time duration of the display.

5. The communication system according to claim 1 wherein the location of the display of the interaction symbol on the display unit can be changed in a variable manner.

6. The communication system according to claim 3 wherein the display mode of the interaction symbol is a function of a specific dialog state and/or a specific dialog situation upon reaching a dialog state.

7. The communication system according to claim 5 wherein the location of the display of the interaction symbol on the display unit depends on the information that is currently displayed in addition to an interaction symbol and/or that is to be displayed thereafter.

8. The communication system according to claim 1 wherein an interaction symbol is designed for signaling additional information, which is kept ready on a topic in addition to the already communicated information, or for signaling a standby function of an operating state of a receiving unit of the communication system for receiving speech signals of the natural person or for changing the perspective and/or the size of information, graphically depicted in addition to the interaction symbol.

9. The communication system according to claim 1 wherein an interaction symbol is designed for signaling a question or a command of the virtual being to the natural person.

10. The communication system according to claim 1 wherein a plurality of interaction symbols can be displayed at least temporarily at the same time on the display unit.

11. The communication system according to claim 10 wherein the number and/or which of the interaction symbols can be depicted on the display unit is variable as a function of a specific dialog state and/or a specific dialog situation after a specific dialog state.

12. The communication system according to claim 1 wherein the displayed interaction symbol is designed as an operating element, which can be selected.

13. The communication system according to claim 1 wherein the display unit is arranged in a vehicle;

and the natural person is an occupant of the vehicle.

14. The communication system according to claim 1, wherein at least one interaction symbol is displayed only on demand, in response to an event occurring with respect to the dialog between the virtual being and the natural person.

15. The communication system according to claim 1, wherein the at least one interaction symbol dynamically changes according to at least one of changing size, changing color, or flashing, according to the temporal progression and content of the dialog between the virtual being and the natural person.

16. The communication system according to claim 1, wherein at least one interaction symbol is selectable to change at least one of a viewing angle, viewing perspective, or zoom amount, of graphically depicted information displayed by the display unit during the dialog between the virtual being and the natural person.

17. A method for representing information in a communication between a virtual being with a natural person, the method comprising:

visually displaying a virtual being on a display unit of a communication system; and

conducting a natural speech dialog between the virtual being and the natural person by transmitting acoustical signals to the natural person and receiving acoustical signals from the natural person, the acoustical signals including speech signals,

wherein the displaying further comprises displaying at least one interaction symbol, which assists the natural speech dialog between the virtual being and the natural person in such a way that an achieved dialog state is displayed; and

/or as a function of the achieved dialog state, additional information and/or information can be retrieved in a redundant manner,

wherein at least one interaction symbol displayed on the display unit dynamically changes according to a temporal progression and content of a dialog between the virtual being and the natural person.

18. A communication system comprising:

a device including means responsive to material speech for generating selective responsive virtual speech to provide a speech dialog between a natural person and a virtual person, and means operable by said natural person for generating a predetermined response,

wherein the device includes a transmitting unit to transmit acoustical signals to the natural person and a receiving unit to receive acoustical signals from the natural person, to conduct a natural speech dialog between the virtual person and the natural person, the acoustical signals including speech signals,

wherein the device displays at least one interaction symbol which dynamically changes according to a temporal progression and content of a dialog between the virtual person and the natural person.

19. A system according to claim 18 wherein said device includes a display screen and said predetermined response means includes a touch activated portion of said screen.

20. A system according to claim 19 wherein operation of said touch activated portion of said screen generates at least one of a predetermined display on said screen and a virtual speech response.

21. A system according to claim 19 wherein operation of said touch activated portion of said display screen operates to index forwardly or rearwardly one of a virtual speech and a visual display response.

22. A system according to claim 18 wherein said device is operable to generate at least one of a virtual speech response and display screen response, in response to a natural speech input.

23. A system according to claim 18 wherein said device is disposed in vehicle and said natural person is an occupant of said vehicle.
