Solution Overview

Problem

Existing speech input systems face reliability and complexity issues due to recognition errors and ambiguities, leading to incorrect command execution and difficulty for users to distinguish between possible commands.

Innovation Solution

An electronic device and method that receives input signals, determines multiple possible commands, and provides output information showing the effects associated with each command, allowing users to easily select the intended action, with visual display and confidence parameter highlighting to enhance reliability and simplicity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system presents a list of possible commands to the user, then the reliability of command identification is improved, but the device complexity and user burden increase

Engineering Contradiction:

Improvecommand identification reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by proactively displaying multiple possible commands and their effects before the user needs to make a selection. This allows the user to review the options and their consequences in advance, making the final selection more reliable and reducing the need for repeated interactions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary element - a visual display interface that shows the effects of different commands. This intermediary helps bridge the gap between the user's speech input and the system's command execution by providing a clear view of what each command will do, making the selection process more reliable without significantly increasing complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the system asks the user to repeat the command when ambiguities are large, then the reliability is improved, but the loss of time and user frustration increase

Engineering Contradiction:

Improvecommand recognition accuracyVSAvoidtime for command repetition

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Instead of waiting for recognition failure and then asking for repetition, the system performs a preliminary action by displaying multiple possible commands and their effects immediately after initial recognition. This allows the user to confirm or correct the intended command in a single interaction, reducing time loss and frustration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides immediate feedback by showing the user what commands were recognized and what effects they will have. This feedback loop allows the user to verify the recognition accuracy and make corrections if needed, improving reliability without requiring multiple repetition cycles.

Inventive Principle:

Principle #23Feedback

3Productivity

If the system executes the most probable command automatically, then the productivity is improved, but the reliability decreases due to potential wrong execution

Engineering Contradiction:

Improvecommand execution speedVSAvoidcommand execution accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs a preliminary display of the most probable command along with alternative commands and their effects before execution. This allows the user to quickly verify the intended command with a single glance and confirm if needed, maintaining high productivity while improving reliability through visual verification.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the parameter of information presentation by displaying not just the command but also its effects and alternative interpretations. This parameter change allows the user to make faster, more accurate decisions by having all relevant information available, thus improving both productivity and reliability.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If the system provides detailed information about command effects, then the reliability of command selection is improved, but the device complexity increases

Engineering Contradiction:

Improvecommand selection accuracyVSAvoidinterface complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the information about command effects into distinct, organized portions for each possible command. Each command is presented with its specific effects separated from other commands, making the information easier to process and compare without overwhelming the user, thus improving reliability without excessive complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system uses visual differentiation (such as highlighting or color coding) to emphasize important information about command effects. This helps the user quickly distinguish between different commands and their consequences, improving command selection reliability while maintaining a clean, manageable interface design.

Inventive Principle:

Principle #32Color changes
