Vehicle Reporting Apparatus Context-Aware Speech Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reporting apparatuses in vehicles lack the ability to determine when to report speech input information effectively, as the utility of the information changes with time, weather, and occupancy status, leading to unnecessary annoyance for drivers.
Innovation Solution
A reporting apparatus that acquires vehicle positional information and status determination information, such as time, weather, and occupancy, to compare with stored data and only report speech input information when the current status matches the stored status, using a similarity determination section to decide on reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speech input information is reported each time the current position and travel direction match the registered position and direction, then the driver receives timely information, but the driver is annoyed by unnecessary repetitions when the information is not useful under current conditions
Solution Approach 1:
The system changes the reporting parameters by introducing status determination information (time, weather, occupancy) as additional conditions for reporting. The reporting processor compares current status with stored status to determine whether to report, transforming the simple position-matching system into a multi-parameter decision system that adapts to changing conditions.
2Loss of information
If the system stores and reports all speech input information based on position and direction matching, then comprehensive information is provided, but the system complexity increases due to status monitoring and comparison
Solution Approach 1:
The system performs preliminary actions by storing status determination information (time, weather, occupancy) together with the speech input information in the storage section. This preliminary capture of contextual data enables later comparison without requiring complex real-time analysis, simplifying the reporting decision process.
Data Source
AI summary
In a vehicle, positional information of the vehicle and status determination information are serially acquired. Each time a user speaks a speech, speech data is acquired. A storage section stores the acquired speech data, and the positional information and status determination information acquired when the speech data is acquired, in association in a memory, as stored speech data, stored positional information, and stored status determination information. For each stored speech data in the memory, a determination is made whether a first status indicated by the stored positional information and stored status determination information associated with the stored speech data is similar to a second status indicated by the positional information and status determination information newly acquired at a current time. A reporting processor reports, to a driver, information based on the stored speech data when the determination is affirmed.
