Dialog Flow Adaptation via Dynamic Focus Stack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for speech recognition in server/client architectures, such as those used on the Internet, face challenges in maintaining a logical dialog flow when users provide multiple pieces of information at once, leading to confusion and inefficient information processing.
Innovation Solution
The implementation of controls that adapt dialogue flow to focus on the user's most recent inputs by using a stack to prioritize recognition results, ensuring that the system confirms or asks about the most recently provided information, thereby maintaining clarity and efficiency in data entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system allows users to provide multiple pieces of information in one sentence, then information input efficiency is improved, but dialog flow logic becomes difficult to maintain and user confusion increases
Solution Approach 1:
The patent segments the multi-information input into individual focus items that are processed separately. Each piece of information the user provides is broken down into discrete focus items with associated questions, allowing the system to handle multiple inputs systematically rather than as a single complex block, thus maintaining dialog flow logic while preserving input efficiency
Solution Approach 2:
The patent implements a dynamic focus stack that adapts to user inputs in real-time. The stack dynamically adds, removes, and prioritizes focus items based on the sequence and type of information provided by the user, enabling the system to maintain logical dialog flow despite varying input patterns and multiple simultaneous information pieces
2Device complexity
If the system follows a hard-coded dialog path, then dialog flow control is simplified, but the system appears to ignore user information and processing efficiency decreases
Solution Approach 1:
The patent replaces hard-coded dialog paths with a dynamic focus stack that automatically adapts to user inputs. The stack dynamically determines which information to process next based on what the user has already provided, eliminating the need for predetermined rigid paths while maintaining simple control logic through stack-based management
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors the focus stack and user inputs to determine the next appropriate action. The stack provides feedback about which focus items remain to be addressed, allowing the system to efficiently process information in a logical sequence without requiring complex hard-coded paths
3Stability of the object's composition
If the system processes information in the order questions are asked, then dialog structure is maintained, but recently provided information may be overlooked and user confusion increases
Solution Approach 1:
The patent implements a dynamic focus stack that prioritizes recently provided information by adding it to the top of the stack. This ensures that the most recent user inputs are processed first, preventing information loss while maintaining dialog structure through systematic stack management that adapts to the conversation flow
Solution Approach 2:
The patent ensures continuous processing of user information by maintaining an active focus stack that never loses track of pending items. The stack continuously manages the sequence of information to be processed, ensuring that recently provided information is immediately addressed without interruption or loss, while maintaining overall dialog structure

AI summary
Controls are provided for a web server to generate client side markups that include recognition and/or audible prompting. The controls comprise elements of a dialog such as a question, answer, confirmation, command or statement. A module forms a dialog by making use of the information carried in the controls. The dialog follows a selected order of prompting and receiving input from a user as related to the order of the controls, and departs from the selected order as a function of responses from the user.
