In-Cabin Speech Suggestions Using Display-Interaction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dialogue systems in vehicles require users to input speech that is understandable and processable, but often fail to provide appropriate speech suggestions tailored to the user and their current situation, potentially distracting the driver.
Innovation Solution
A method to suggest speech by determining a user as a target based on their interaction with vehicle displays, considering factors like seating location, age, gender, and vehicle knowledge level, and adjusting content and output location to minimize distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech suggestions are provided to all users regardless of their current activity, then user interaction with the dialogue system is enhanced, but driver distraction increases
Solution Approach 1:
The system applies different quality levels of speech suggestion delivery to different users based on their role and current state. The driver receives speech suggestions only when not engaged in display interaction, while passengers receive suggestions continuously. This localized differentiation resolves the contradiction by tailoring the interaction enhancement to specific users without universally increasing driver distraction.
Solution Approach 2:
The system dynamically adjusts speech suggestion delivery based on real-time detection of user display interaction. When a driver is detected interacting with the display, speech suggestions are temporarily suspended for that user. This dynamic adaptation allows the system to enhance user interaction when appropriate while minimizing driver distraction during critical driving phases.
2Reliability
If speech suggestions are customized based on user characteristics, then speech suggestion effectiveness is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by detecting user characteristics (seating location, age, gender, knowledge level) and display interaction status before delivering speech suggestions. This advance preparation allows the system to customize speech suggestions appropriately without adding complexity during the actual suggestion delivery phase, resolving the contradiction between effectiveness and complexity.
3Productivity
If speech suggestions are provided continuously, then user engagement with the dialogue system is enhanced, but interference with driving tasks increases
Solution Approach 1:
The system implements periodic checking of user display interaction status to determine appropriate speech suggestion delivery timing. Instead of continuous speech suggestion provision, the system periodically assesses whether the driver is engaged with the display and adjusts speech suggestion delivery accordingly. This periodic action maintains user engagement while preventing interference with driving tasks during critical periods.

AI summary
A method of suggesting a speech and a recording medium which may suggest an appropriate speech by determining a speech suggestion target using various information that a vehicle may obtain, includes obtaining a user image where at least one user inside the vehicle is photographed; detecting a user looking at a display inside the vehicle among the at least one user, based on the obtained user image; and determining a target user which is a target of the speech suggestion, based on a result of the detecting.
