Abstract

GUI form code comprising a set of GUI elements can be imported. A user interface description can be generated from the GUI form code that has an element corresponding to each GUI element. For each user interface element converted from a corresponding to one of the GUI elements, a user interface element type can be determined as can temporal associations between the user interface elements. A Conversation User Interface (CUI) code corresponding to the GUI form code can be created from the user interface description. When creating the CUI code for each of the user interface elements, different and rules to convert the user interface element into CUI code can be used depending on a user interface element type of the user interface element being converted. When creating the CUI code, the user interface elements can be temporally ordered based on the pre-determined spatio-temporal associations between the graphical user interface (GUI) elements.

for each of user interface element converted from a corresponding to one of the GUI elements, determining a user interface element type for the user interface element, wherein said determined user interface element type is one of a plurality of different element types;

for each user interface element, determining temporal associations between the user interface element and other ones of the user interface elements, wherein said temporal associations are dependent upon characteristics of the corresponding GUI element relative to other ones of the GUI elements within the GUI form code;

creating Conversation User Interface (CUI) code corresponding to the GUI form code from the user interface description;

when creating the Conversation User Interface (CUI) code for each of the user interface elements of the user interface description, utilizing a different and rules to convert the user interface element into Conversation User Interface (CUI) code depending on a user interface element type of the user interface element being converted, and

when creating the conversation user interface code, temporally ordering the user interface elements based on the determined temporal associations between the user interface elements.

2. The method of claim 1, wherein the user interface description corresponds to the GUI form code, but is language independent, where the GUI form code is specific to a programming language.

3. The method of claim 2, wherein the conversion from GUI form code to the user interface description is performed by executing an injective function that preserves distinctness in that every element of the injective function'"'"'s codomain is mapped to by at most one element of the injective function'"'"'s domain, wherein executing the injective function against different GUI form code segments that are substantially equivalent to each other yet written in different programming languages results in the same user interface description being generated.

4. The method of claim 1, wherein the GUI form code natively lacks conversation user interface specific elements, which are generated automatically by programmatic routines without manual user coding for the conversation user interface code being required.

5. The method of claim 1, wherein the conversation user interface (CUI) code and the graphical form code is integrated and synchronized to form multi-modal user interface code having a visual and a voice interactive modality, wherein the voice interactive modality uses the conversation user interface code to accept and process speech input and to generate speech output, where the speech input and speech output is synchronized with GUI elements of the GUI form code.

6. The method of claim 5, wherein the visual modality of the multi-modal user interface comprises a chat section within which the speech input is visually presented as text and within which speech output is visually presented as text, wherein the speech input and speech output are handled in accordance with the conversation user interface (CUI) code.

7. The method of claim 1, wherein the determined temporal associations between the user interface elements is determined based on a spatial orientation of corresponding GUI elements of the GUI form code, of parent-child relationships between the corresponding GUI elements in the GUI form code, and of tab order of the corresponding GUI elements in the GUI form code.

8. The method of claim 1, wherein said user interface element type is determined from a set of user interface element types comprising an association type for an assertion element, an action type for an action element, an interrogator type for an interrogatory element, a container type for a container element, and a display type for a display element.

9. The method of claim 8, wherein the determined user interface element type for at least one of the user interface elements is for an assertion element.

10. The method of claim 8, wherein the determined user interface element type for at least one of the user interface elements is for an action element.

11. The method of claim 8, wherein the determined user interface element type for at least one of the user interface elements is for an interrogatory element.

12. The method of claim 8, wherein the determined user interface element type for at least one of the user interface elements is for a container element.

13. The method of claim 8, wherein the determined user interface element type for at least one of the user interface elements is for a display element.

14. The method of claim 1, further comprising:

transforming the user interface description into a conversation user interface (CUI) flow, wherein said conversation user interface (CUI) flow comprises a plurality of nodes and edges, each node representing a task, each edge representing a temporal flow in a dialog, wherein the conversation user interface (CUI) code is generated from the conversation user interface (CUI) flow.

15. The method of claim 1, further comprising:

determining whether disambiguation is needed for any of the GUI elements when generating the user interface description;

when no disambiguation is needed, automatically generating the user interface description from the GUI form code without any user input; and

when disambiguation is needed, prompting a user for disambiguation input for each GUI element for which disambiguation is needed, receiving a user response to the prompting, disambiguating otherwise ambiguous GUI elements utilizing the user response when generating the user interface description.

16. The method of claim 1, further comprising:

generating a Conversation User Interface (CUI) activity tree from the user interface description;
