Voice-Guided Travel Information Feedback for Route Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving support apparatuses fail to intuitively and easily allow users to specify positions and routes, such as turning or stopping, when inputting commands through touch interfaces, as they do not provide clear visual or auditory feedback for confirming intended actions.
Innovation Solution
A travel information processing apparatus that uses voice recognition and image processing to identify objects and their positional relationships, outputting image or voice data for user confirmation, allowing users to specify driving operations through voice commands and visually or audibly confirming the intended actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is used to specify driving operations, then ease of operation is improved, but reliability deteriorates due to inability to confirm intended actions
Solution Approach 1:
The system provides feedback by outputting image data or voice data that indicates the specified object, allowing the user to confirm whether the object estimated from voice data matches the object they intended to specify. This feedback loop resolves the contradiction by enabling easy voice-based operation while ensuring reliability through user confirmation.
2Ease of operation
If touch interface is used to input commands, then ease of operation is improved, but versatility deteriorates as positions and routes cannot be specified
Solution Approach 1:
The system combines voice recognition with image and voice output to create a multi-functional interface. The same voice-based interface can specify not only position changes but also traveling routes including turns and stops, making the system versatile while maintaining ease of operation.
3Measurement precision
If object estimation from voice data is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system uses image data or voice data as an intermediary to convey information about the specified object to the user. This intermediary allows the system to achieve precise object identification through voice recognition while keeping the overall device complexity manageable by using existing display and audio output components.

AI summary
A travel information processing apparatus comprises a voice input device 11 configured to input voice data of a user, an output device 12, 16, 17, 18 configured to specify an object by estimating from the voice data based on a word extracted from the voice data and indicating the object around a traveling route and a word extracted from the voice data and indicating a positional relationship of the object and output image data or voice data indicating a specified object; and a travel information processor configured to change a traveling motion of a subject vehicle based on the specified object.
