Abstract

Dynamic tutorial generation for user help and user guidance in generating a property of an exemplar object is provided. The user identifies the exemplar object, the object or one of its properties is analyzed, user operations for producing the property of the object are determined, and the determined user operations are presented. Path finding logic may be used to identify a sequence of states using transform operations to reach a goal state with the desired property of the object. Transformation operations may be applied and the resulting states may each be compared to the goal state using a heuristic that yields a similarity metric between each of the resulting states and the goal state.

Claims

1. A computer-implemented method of providing user guidance for reproducing a property of a copyable object from content, the method comprising:

receiving from a user an identification of the copyable object, wherein the copyable object comprises a property;

generating a goal state comprising a value associated with the property of the identified copyable object;

generating an initial state comprising the property of the identified copyable object;

applying a set of transformation operations to the initial state to generate a plurality of temporary states, each of the plurality of temporary states having a temporary value associated with the property;

comparing the temporary value of each of the plurality of temporary states with the value of the goal state to determine a matching temporary state of the plurality of temporary states that most closely matches the goal state;

identifying a user operation for reproducing the property of the identified copyable object in a new object based on the transformation operations applied to generate the determined matching temporary state; and

presenting, to the user, at least one option for creating the new object using the identified user operation.

2. The method of claim 1, wherein said determining the user operation comprises using path finding logic to identify a sequence of states that includes a goal state that includes the property of the identified copyable object.

3. A non-transitory processor-readable medium incorporating a program of instructions for performing a method according to claim 2.

4. A non-transitory processor-readable medium incorporating a program of instructions for performing a method according to claim 1.

5. The method of claim 1, wherein said determining the user operation comprises:

generating a goal state comprising a value associated with the property of the identified copyable object;

generating an initial state comprising the property of the identified copyable object;

applying a set of transformation operations to the initial state to generate a plurality of temporary states, each of the plurality of temporary states having a temporary value associated with the property;

comparing the temporary value of each of the plurality of temporary states with the value of the goal state to determine a matching temporary state of the plurality of temporary states that most closely matches the goal state;

applying a second set of transformation operations to the determined matching temporary state; and

identifying the user operation based on the sets of transformation operations applied.

6. A non-transitory processor-readable medium incorporating a program of instructions for performing a method according to claim 5.

7. The method of claim 1, wherein said determining the user operation comprises:

generating a goal state comprising a value associated with the property of the identified copyable object;

generating an initial state comprising the property of the identified copyable object;

applying a set of transformation operations to the initial state to generate a plurality of temporary states, each of the plurality of temporary states having a temporary value associated with the property;

comparing the temporary value of each of the plurality of temporary states with the value of the goal state to determine matching temporary state of the plurality of temporary states that most closely matches the goal state;

eliminating all temporary states of the plurality of temporary states except the determined matching temporary state; and

applying a further set of transformation operations to the determined matching temporary state to generate a plurality of third states.

8. A non-transitory processor-readable medium incorporating a program of instructions for performing a method according to claim 7.

9. The method of claim 1, further comprising enabling the user to identify the property of the identified copyable object.

10. The method of claim 1, further comprising:

identifying a second property of the identified copyable object; and

presenting, to the user, a second user operation for producing the second property in the new object.

11. A non-transitory processor-readable medium incorporating a program of instructions for performing a method according to claim 10.

12. The method of claim 1, comprising:

identifying all properties of the identified copyable object; and

presenting, to the user, user operations for producing the new object with all the identified properties of the identified copyable object.

13. The method of claim 1, wherein the identification of the copyable object comprises selecting the copyable object as content of a paste buffer.

14. The method of claim 1, wherein the identification of the copyable object comprises selecting a pointer to the copyable object.

15. The method of claim 1, wherein said presenting, to the user, the at least one option for creating the new object using the determined user operation comprises providing a visual presentation to the user.

16. The method of claim 1, wherein said presenting, to the user, the at least one option for creating the new object using the determined user operation comprises displaying a menu control sequence.

17. The method of claim 1, wherein said presenting, to the user, the at least one option for creating the new object using the determined user operation comprises outputting an audio signal.

18. The method of claim 1, wherein said presenting, to the user, the at least one option for creating the new object using the determined user operation comprises displaying animation showing the user operation.

19. A non-transitory processor-readable medium incorporating a program of instructions for performing a method according to claim 18.

20. The method of claim 1, further comprising:

receiving, from the user, a selection from the determined at least one user operation; and

presenting a plurality of sub-operations based on the user selection.

21. The method of claim 1, further comprising:

identifying all properties of the identified copyable object;

presenting, to the user, user operations for producing the new object with all the identified properties of the identified copyable object;

receiving, from the user, a selection from the presented user operations; and

presenting a plurality of sub-operations based on the selected user operation.

22. A non-transitory processor-readable medium incorporating a program of instructions for performing a method according to claim 21.

23. A non-transitory processor-readable medium incorporating a program of instructions for performing a method according to claim 1.

24. A computer-implemented method of providing user guidance for reproducing a property of a copyable object from content, the method comprising:

receiving from a user an identification of the copyable object, wherein the copyable object comprises a property;

generating a goal state comprising a value associated with the property of the identified copyable object;

generating an initial state comprising the property of the identified copyable object;

applying a set of transformation operations to the initial state to generate a plurality of temporary states, each of the plurality of temporary states having a temporary value associated with the property;

comparing the temporary value of each of the plurality of temporary states with the value of the goal state to determine a matching temporary state of the plurality of temporary states that most closely matches the goal state;

identifying a user operation for reproducing the property of the identified copyable object in a new object based on the transformation operations applied to generate the determined matching temporary state; and

creating the new object using the identified user operation.
