Abstract

Roughly described, a context reactive user interface which offers user-selectable on-screen choices or hints to help the user follow up in the context of his or her previous interactions. Alternatively or additionally, the system can offer on-screen choices which, when selected by the user, can invoke one or more back-end applications with entry fields pre-filled from the user'"'"'s previous interactions or from other contextual information.

Claims

1. A user interface method, comprising the steps of:

providing a network including a plurality of agents;

developing a first interpretation path through the agents in the network in dependence upon the content of first user input;

offering to a user a set of at least one user-selectable user interface item in dependence upon the first interpretation path; and

invoking a first back-end application in response to user-selection of one of the user interface items, including supplying to the first back-end application a first field value filled in dependence upon the user'"'"'s context.

2. A method according to claim 1, wherein each agent in the plurality of agents has at least one interpretation policy having a policy condition, each of the interpretation policies making a claim on at least part of a message provided to the agent if the condition of the interpretation policy is satisfied, wherein each agent that has immediately downchain agents includes a reference in its policy conditions to any claims made by the immediately downchain agents, and wherein the step of developing a first interpretation path comprises the steps of:

providing a message identifying the first user input to a particular one of the agents in the plurality;

each agent receiving the message forwarding it to each of its immediately downchain agents;

each agent receiving the message responding with any claims made by its interpretation policies; and

the particular agent determining a first winning claim from among all claims returned to it from its immediately downchain agents, the first interpretation path including all agents that contributed to the winning claim.

3. A method according to claim 1, further comprising the step of offering user-selectable preliminary user interface items corresponding to at least one of the agents in the first interpretation path,

and wherein the step of offering a set of at least one user-selectable user interface item in dependence upon the first interpretation path, comprises the step of offering to the user a set of at least one user-selectable user interface item in dependence upon a user-selected one of the preliminary user interface items.

4. A method according to claim 3, wherein a first subset of the agents in the network are predefined as belonging to a first grouping of agents, a second subset of the agents in the network are predefined as belonging to a second grouping of agents, the first subset of agents being not completely identical with the second subset of agents, the user-selected one of the preliminary user interface items being predefined as belonging to the first grouping of agents,

and wherein the step of offering to the user a set of at least one user-selectable user interface item in dependence upon a user-selected one of the preliminary user interface items, comprises the step of offering to the user a user-selectable user interface item corresponding to another agent predefined as sharing a grouping with the user-selected one of the preliminary user interface items.

5. A method according to claim 3, wherein the step of offering to the user a set of at least one user-selectable user interface item in dependence upon a user-selected one of the preliminary user interface items, comprises the step of offering to the user a set of at least one user-selectable user interface item in dependence upon both the user-selected one of the preliminary user interface items and user context information not derived-from user input.

6. A method according to claim 3, wherein the step of offering to the user a set of at least one user-selectable user interface item in dependence upon a user-selected one of the preliminary user interface items, comprises the step of offering to the user a set of at least one user-selectable user interface item in dependence upon both the user-selected one of the preliminary user interface items and a user profile.

7. A method according to claim 1, wherein the first back-end application has an object type corresponding to the user-selected user interface item, the object type in said first back-end application further having at least the first field,

and wherein the step of invoking comprises the step of supplying to the first back-end application a first field value filled in dependence upon a field value identified in user input no more recent than the first user input.

8. A method according to claim 7, wherein the step of invoking comprises the step of supplying to the first back-end application a first field value filled in dependence upon a field value identified in user input prior to the first user input.

9. A method according to claim 7, wherein the step of invoking comprises the step of supplying to the first back-end application a first field value filled in dependence upon a value most recently identified for the first field in user input.

10. A method according to claim 1, wherein the first back-end application has an object type corresponding to the user-selected user interface item, the object type in said first back-end application further having at least the first field,

and wherein the step of invoking comprises the step of supplying to the first back-end application a first field value filled in dependence upon user context information not derived from user input.

11. A method according to claim 1, wherein the first back-end application has an object type corresponding to the user-selected user interface item, the object type in said first back-end application further having at least the first field,

and wherein the step of invoking comprises the step of supplying to the first back-end application a first field value filled in dependence upon a user profile.

12. A method according to claim 1, wherein the agents in the first interpretation path include a first object agent for recognizing user intent to identify a first object type present in the back-end application,

wherein the back-end application permits objects of the first object type to have a first field,

wherein the agent network includes a first field agent downchain of the first object agent,

wherein the user-selected one of the user interface items corresponds to the first object agent,

and wherein the step of supplying to the first back-end application a first field value filled in dependence upon the user'"'"'s context comprises the step of identifying the first field in dependence upon the agents downchain in the agent network from the first object agent.

13. A method according to claim 1, wherein the user-selected user interface item corresponds to a first object type of the first back-end application;

wherein the first back-end application permits objects of the first object type to have a field of a first field type,

and wherein the step of invoking a first back-end application in response to user-selection of one of the user interface items, comprises the steps of;

displaying a form to the user including fields for the first object type, including a field of the first field type;

pre-filling the field of the first field type with the first field value; and

supplying to the first back-end application the field values present in the form in response to a user commit indication.

14. A method according to claim 13, wherein the form further includes a command user interface item corresponding to a command applicable to objects of the first object type,

and wherein the user commit indication comprises user selection of the command user interface item.

15. A method according to claim 1, wherein the user-selected user interface item corresponds to a first object type of the first back-end application;

wherein the first back-end application permits objects of the first object type to have a field of a first field type,

wherein the first back-end application permits a first command for use on objects of the first object type,

and wherein the step of-invoking a first back-end application in response to user-selection of one of the user interface items, comprises the steps of;

displaying a form to the user including fields for the first object type, including a field of the first field type and a user interface item corresponding to the first command; and

supplying to the first back-end application the field values present in the form in response to user selection of the first command user interface item.

16. A method according to claim 1, further comprising the steps of:

invoking a preliminary back-end application in response to the step of developing a first interpretation path, the preliminary back-end application being different from the first back-end application.
