Mobile Voice-Speech Driving Mode for Audible 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 settings for volume, replay speed, and font size to enhance usability during driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GUI feedback is provided during driving, then detailed information is available, but user safety is compromised due to visual distraction
Solution Approach 1:
The feedback information is segmented into two channels: audible feedback for essential information and GUI feedback for detailed information. This segmentation allows the system to deliver complete information while reducing visual distraction by handling critical feedback through audio during driving mode
Solution Approach 2:
Audible feedback serves as an intermediary medium to convey essential information to the user during driving. Instead of requiring direct visual contact with the screen, the system uses audio as a mediator to transmit feedback, thereby maintaining information delivery while eliminating visual distraction
2Object-affected harmful factors
If audible feedback is provided at maximum volume during driving, then user safety is improved, but device complexity increases due to mode management
Solution Approach 1:
The system automatically detects driving conditions through sensor data (accelerometer, gyroscope, microphone) and autonomously switches to driving mode with appropriate audio feedback settings. This self-service approach minimizes manual intervention and reduces the perceived complexity for the user, as the system manages modes automatically based on detected conditions
3Object-affected harmful factors
If visual information is minimized during driving, then user safety is enhanced, but information accessibility is reduced
Solution Approach 1:
The system transitions information delivery from the visual dimension to the auditory dimension during driving mode. By changing the dimension of feedback delivery from visual (GUI) to auditory (speaker output), the system maintains full information accessibility while eliminating visual distraction, as audio information can be perceived without visual engagement
Data Source
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.
