Vehicle Navigation Trigger Button for Voice Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle equipment with voice recognition systems often require inconvenient timing for initiating voice recognition, disrupting the user's experience and operational efficiency.
Innovation Solution
A navigation apparatus with a protrusion unit featuring a trigger button that allows easy operation by offsetting the button from the display screen's rim, reducing accidental presses and enhancing touch detection without requiring eye movement, coupled with a voice recognition system that limits screen operations during vehicle travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is initiated by conventional means (e.g., automatic timing or separate control), then voice recognition function is available, but the initiation timing deviates from user intent and convenience is reduced
Solution Approach 1:
The trigger button is pre-configured and positioned on the display screen to enable immediate voice recognition initiation when needed. The system is prepared in advance with the button readily accessible, eliminating timing deviations and allowing users to start voice recognition exactly when they intend without waiting for automatic triggers or complex setup.
2Ease of operation
If the trigger button is positioned on the display screen rim for easy access, then operation convenience is improved, but accidental presses increase
Solution Approach 1:
The trigger button is positioned at a specific location on the display screen that balances accessibility with accidental press prevention. By carefully selecting the button's placement within the display area, the design optimizes local characteristics to ensure the button is easily reachable while minimizing the risk of unintentional activation during normal use.
3Adaptability or versatility
If screen operations are allowed during vehicle travel, then user flexibility is maintained, but driver safety is compromised
Solution Approach 1:
The system dynamically adjusts screen operation availability based on vehicle travel state. When the vehicle is detected to be in motion, screen operations are restricted to prevent driver distraction. When stationary, full screen operations are restored. This dynamic adaptation allows the system to maintain driver safety during travel while preserving user flexibility when the vehicle is parked.
Solution Approach 2:
The trigger button serves as an intermediary mechanism that enables voice recognition initiation without requiring full screen interaction. Users can activate voice recognition through this dedicated button even when screen operations are restricted during vehicle travel, providing a safe intermediate pathway for essential functions while maintaining driver safety.
