Virtual Assistant Ambiguous Command Execution via Reversible Action Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In public safety environments, virtual assistants struggle to accurately interpret verbal commands with sufficient confidence, leading to potential delays or errors, particularly when users are under high cognitive load, which can compromise situational awareness and safety.
Innovation Solution
The virtual assistant identifies the most likely command with a given voice instruction, retrieves a standard operating procedure (SOP) associated with that command, and executes reversible actions without confirmation, requesting confirmation only for irreversible actions, ensuring safety and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the virtual assistant requests confirmation for every command, then accuracy improves, but response time deteriorates
Solution Approach 1:
The system applies partial confirmation by requesting user confirmation only for irreversible actions while automatically executing reversible actions without confirmation. This selective approach reduces the number of confirmation prompts while maintaining safety for critical operations, thereby improving response time without completely sacrificing accuracy.
Solution Approach 2:
The command execution process is segmented into two distinct paths: one for reversible actions that can be executed automatically, and another for irreversible actions that require confirmation. This segmentation allows the system to handle different types of actions with appropriate levels of caution, optimizing both speed and safety.
2Productivity
If the virtual assistant executes commands automatically, then productivity improves, but error rate worsens
Solution Approach 1:
The system executes commands partially automatically based on their reversibility characteristics. Reversible actions are executed automatically to maintain high productivity, while irreversible actions trigger confirmation prompts to prevent errors. This selective automation optimizes the balance between efficiency and error prevention.
Solution Approach 2:
The system prepares confirmation prompts in advance for irreversible actions before execution begins. By anticipating which actions require confirmation and preparing the appropriate safety checks beforehand, the system can maintain smooth execution flow while ensuring errors are prevented through pre-planned verification steps.
3Reliability
If the virtual assistant asks for clarification on ambiguous commands, then accuracy improves, but cognitive load on user worsens
Solution Approach 1:
The system applies partial clarification by seeking user confirmation only when an ambiguous command involves irreversible actions. For ambiguous commands that only involve reversible actions, the system makes its best interpretation and executes without further clarification. This reduces the frequency of clarification requests while maintaining accuracy for critical operations.

AI summary
Techniques for virtual assistant execution of ambiguous commands is provided. A voice instruction from a user may be received at a virtual assistant. The voice instruction may request the virtual assistant to perform a command. The command that is most likely being requested by the voice instruction from the user is identified. An ordered set of actions to execute when performing the command may be retrieved. Each action of the ordered set of actions may indicate if the action is reversible. Each action of the ordered set of actions may be executed in order until a not reversible action is reached or no further actions are in the ordered set of actions.
