Vehicle Audio Control for Priority Interruption and Resume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted devices struggle to allow users to fully grasp details of suspended content information, particularly highway radio information, due to interrupted reproduction and difficulty in understanding voice readings with changed intonation.
Innovation Solution
A vehicle-mounted device with communication, reproduction, and control means that suspends lower-priority content information reproduction to start and resume higher-priority content, and specifically resumes suspended content information from the beginning or a designated position, ensuring uninterrupted audio reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reproduction of content information is suspended to prioritize other information, then priority information can be delivered timely, but user understanding of suspended content details deteriorates
Solution Approach 1:
The system performs preliminary actions by saving the reproduction state (position, intonation settings) before suspension occurs. When resuming, it restores these pre-saved settings to ensure continuous understanding. This preliminary preservation of state information allows the system to maintain user comprehension despite interruptions.
Solution Approach 2:
The system implements feedback mechanisms by monitoring reproduction progress and automatically managing suspension/resumption based on priority information reception. The feedback loop ensures that when high-priority information is received, the system suspends lower-priority content, plays the priority information, then resumes the original content with appropriate state restoration.
2Productivity
If voice reading intonation is changed to convey information efficiently, then information delivery speed improves, but user comprehension of detailed content deteriorates
Solution Approach 1:
The system dynamically adjusts intonation settings based on the type of content being reproduced. For highway radio information requiring detailed comprehension, the system maintains natural intonation. For other content types, it may apply different intonation patterns to optimize delivery speed. This dynamic adaptation allows the system to balance speed and comprehension based on content requirements.
3Loss of time
If reproduction resumes from suspended position, then time efficiency improves, but user ability to grasp suspended content details deteriorates
Solution Approach 1:
The system performs preliminary analysis of the suspended content position to determine if it represents a complete thought or sentence boundary. When resuming from positions that may compromise understanding (such as mid-sentence), the system proactively decides to restart from the beginning, ensuring complete content delivery while minimizing time loss.
Solution Approach 2:
The system changes the reproduction parameter (starting position) based on content analysis. Instead of always resuming from the suspended position, it dynamically adjusts the start position to either the original suspension point or the beginning of the content, depending on what best ensures user comprehension while maintaining time efficiency.

AI summary
Reproduction is performed so that the user can grasp the details of content information on long sentence reading the reproduction of which has been suspended. If an vehicle-mounted device (10) receives content information with higher priority of the reproduction than that of the content information on the long sentence reading during the reproduction of the content information on the long sentence reading received from a center apparatus by a reproduction section (step S4; Y), the vehicle-mounted device (10) allows the control of a control unit to suspend the reproduction of the content information on the long sentence reading (step S7) and to start the reproduction of the content information with higher priority (step S8). If the reproduction ends, the vehicle-mounted device (10) allows the reproduction means to resume the suspended reproduction of the content information on the long sentence reading (step S12).
