Display Visibility Control for Voice Operation Mode

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users of devices capable of both voice and panel operations face difficulty in determining which operation mode is active, as existing technologies primarily focus on turning off lights based on user operation rather than indicating the active mode.

Innovation Solution

An information processor with a voice inputter, display, and controller that executes a voice operation mode, reducing display visibility when the voice operation mode is started, allowing users to clearly understand when voice operations are required and focusing on voice inputs without visual distractions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display light is turned off to prompt voice operation, then voice operation focus is improved, but user ability to determine active operation mode deteriorates

Engineering Contradiction:

Improvevoice operation focusVSAvoidoperation mode indication

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent applies color changes by displaying different colors on the display screen to indicate the active operation mode. When voice operation mode is active, the display shows a specific color (e.g., blue background with white text) to inform users of the current mode without requiring the display to be fully visible or distracting from voice input.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

Instead of turning off the display completely to indicate voice operation mode (which would lose visual information), the patent inverts the approach by making the display visible but with modified characteristics (color changes, reduced brightness) that still provide information while directing attention to voice input.

Inventive Principle:

Principle #13The other way round (Inversion)

2Measurement precision

If the display is made less visible during voice operation, then voice command recognition is improved, but display functionality is reduced

Engineering Contradiction:

Improvevoice command recognitionVSAvoiddisplay functionality

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent implements dynamics by dynamically adjusting display characteristics based on the active operation mode. The display transitions between normal visibility for panel operations and reduced visibility with color changes for voice operations, allowing the system to adapt the display state to current operational requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by modifying display parameters such as brightness, color, and contrast when voice operation mode is activated. These parameter changes reduce display visibility enough to minimize distractions and improve voice command recognition while maintaining some visual feedback through color indicators.

Inventive Principle:

Principle #35Parameter changes

AI summary

An information processor including a voice inputter, a display, and a controller is provided. The controller executes a voice operation mode allowing an operation by voice input via the voice inputter, and performs control to reduce visibility of the display when execution of the voice operation mode is started.
