Mobile Voice-Speech Driving Mode With Audible-Only Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice-speech services in mobile terminals are not optimized for situations where users cannot view the screen, such as while driving, leading to safety concerns due to visual distractions.
Innovation Solution
A method and mobile terminal implementation that detects the user's situation and switches to a driving mode, providing audible feedback with maximum volume and summary information to minimize visual distractions, while storing driving mode settings for optimized voice-speech service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GUI feedback is provided to display detailed information on the screen, then information completeness is improved, but user safety deteriorates due to visual distractions during driving
Solution Approach 1:
The system dynamically switches between driving mode and non-driving mode based on sensor detection. When driving mode is detected, the system provides only audible feedback through speaker. When non-driving mode is detected, the system provides both audible and visual (GUI) feedback. This dynamic adaptation resolves the contradiction by adjusting information delivery method according to the user's situation.
Solution Approach 2:
The system changes the parameter of feedback modality based on operating conditions. In driving mode, visual feedback parameter is set to zero (only audible). In non-driving mode, visual feedback parameter is enabled (both audible and visual). This parameter change allows the system to maintain information completeness while ensuring safety during driving.
2Object-affected harmful factors
If only summary information is provided as TTS feedback, then user safety is improved by reducing visual distractions, but information completeness deteriorates
Solution Approach 1:
The system dynamically adjusts the amount of information provided through TTS feedback based on the detected operating mode. In driving mode, the system provides complete information through audible TTS feedback. In non-driving mode, the system provides summary information through TTS and detailed information through GUI. This dynamic adjustment resolves the contradiction between safety and information completeness.
Solution Approach 2:
The system changes the information delivery parameter based on operating conditions. When driving mode is detected, the TTS feedback parameter is set to provide complete information. When non-driving mode is detected, the TTS feedback parameter is adjusted to provide only summary information, with detailed information delivered through visual GUI feedback.
3Object-affected harmful factors
If the voice-speech service is optimized for driving mode with audible feedback only, then user safety is improved, but ease of operation deteriorates for non-driving situations
Solution Approach 1:
The system dynamically adapts its feedback modality based on the detected operating mode. In driving mode, it provides audible feedback only for safety. In non-driving mode, it switches to providing both audible and visual feedback for enhanced ease of operation. This dynamic behavior allows the system to optimize for safety when needed and for ease of operation when safe to do so.
Solution Approach 2:
The system implements multi-functionality by supporting multiple feedback modalities (audible only, audible plus visual) based on operating conditions. The voice-speech service becomes universal across different situations: optimized for safety during driving and optimized for ease of operation during non-driving activities. This universality resolves the contradiction between safety optimization and ease of operation.

AI summary
A method of providing a voice-speech service in a mobile terminal is provided. The method includes receiving sensing information from a sensor unit, determining whether to set an operating mode of the voice-speech service as a driving mode according to the sensing information, and providing an audible feedback according to pre-stored driving mode setting information when an operating mode of the voice-speech service is set as the driving mode.
