Computerized task guidance across devices and applications

A computer-implemented method, comprising:

• accessing, via a first computing device, a digital working task document including a textual task description describing task steps to be completed in performing a task;
• displaying at least a portion of the working task document on a display via the first computing device;
• accessing at least a portion of the working task document via a second computing device that is separate from the first computing device;
• generating a computer-readable task state data structure that represents a state of interaction with the working task document, with the task state data structure being accessible via the first computing device and the second computing device;
• presenting a natural language dialog script representing at least a portion of the working task document via the second computing device;
• in response to receiving visual user input via the first computing device, performing an update to the task state data structure to represent the visual user input, with the visual user input being directed at an item on the working task document on the display, and with the visual user input indicating a state of progress in completing the task;
• and
• in response to receiving a natural language user input command via the second computing device, generating a natural language response that is particular to the task state data structure, with the generating of the natural language response comprising accessing the task state data structure, and with the natural language response providing guidance for performing the task and representing the update to the task state data structure;
• presenting the natural language response via the second computing device.

A computer system comprising:

• at least one processor;
• and
• memory comprising instructions stored thereon that when executed by at least one processor cause at least one processor to perform acts comprising:
• conducting an interactive computer communication session with an authenticated user profile via a first computer application, a second computer application, a shared digital working task document, and a shared digital task state data structure, with the working task document comprising instructions for performing a task, with the task state data structure indicating a state of completion of the task, and with the conducting of the session comprising:
• performing a first update of the task state data structure in response to visual user input received from the user profile via the first computer application, with the visual user input directed at an element of the working task document;
• performing a second update of the task state data structure in response to natural language input received from the user profile via the second computer application;
• providing a first set of task guidance to the user profile via the first computer application in a visual format by displaying at least a portion of the working task document on a computer display, with the first set of task guidance being provided using the working task document and the task state data structure, and with the first set of task guidance representing the first update and the second update;
• and
• providing a second set of task guidance to the user profile via the second computer application in a natural language dialog format, with the second set of task guidance being provided using the working task document and the task state data structure.
