Abstract: Techniques for guiding an interaction with an electronic form via a computing device are described. For example, a form guidance engine is initiated. The form guidance engine maintains a state of the electronic form. The form guidance engine also maintains user information in, for example, a user profile. The user information is associated with a user of the computing device and relates to how the user interacts with the electronic form. Based on the user information, the form guidance engine anticipates a potential interaction with the electronic form given the state. Accordingly and prior to a user request for information about the electronic form, the form guidance engine generates a presentation configured to guide the user to perform the potential interaction with the electronic form via a computing device. A user response to the presentation is received. The form guidance engine performs an action associated with the electronic form and updates the state of the electronic form.

Abstract: Techniques for assisting users electronic forms. One exemplary technique involves initiating a workflow assistant based on user input of the user or a predetermined triggering event to prompt the user to complete the electronic form. The workflow assistant downloads or obtains the electronic form based on a user response and identifies a workflow based on the electronic form. The workflow identifies a sequence of user interactions to complete the electronic form. Identifying the workflow includes developing, based on fields in the electronic form, requests for content of fields from the user and possible predicted answer choices for the content of each of the fields. The workflow assistant then executes the workflow to conduct the user interactions to obtain the content for the fields of the electronic form to complete the electronic form.

Abstract: Techniques for assisting a user with completing an electronic form via a computing device are described. For example, the user operates the computing device to populate fields of the electronic form. Rather than presenting the electronic form at the computing device in order to populate the fields, a form filling engine reformulates the electronic form into a set of input requests. The form filling engine is local or remote to the computing device. Each input request, when presented, provides guidance about at least one field and solicit a user response that is proper for that field. The form filling engine presents the input requests via the computing device one at a time to solicit the user responses. Data from the user responses are used by the form filling engine to populate the fields of the electronic form.
