In-Vehicle Voice Screen Assignment for Multi-User Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice interaction systems in vehicles with multiple screens struggle to effectively manage interactions between multiple users, leading to poor user experience due to simultaneous commands being ignored or displayed on a single screen, rather than leveraging the potential of multiple screens for independent interactions.
Innovation Solution
A voice interaction method that determines a primary and secondary voice screen for each user based on their location, displaying interaction content and identifiers on corresponding screens, prioritizing command processing, and using sound source positioning to manage simultaneous interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users issue voice commands simultaneously in a vehicle with multiple screens, then the system can potentially serve multiple users, but the existing system displays all interactions on a single screen causing confusion and poor user experience
Solution Approach 1:
The patent segments the voice interaction system by user and screen location. Each user's voice commands are associated with a specific screen based on their seating position, dividing the unified voice interaction system into multiple independent interaction channels. This resolves the contradiction by enabling multi-user support while maintaining clear, dedicated display areas for each user.
Solution Approach 2:
The patent implements local quality by assigning different interaction characteristics to different screens based on user location. The primary screen (driver side) receives higher priority commands, while secondary screens (passenger side) receive lower priority commands. This creates localized interaction zones with distinct qualities, allowing simultaneous multi-user interaction without confusion.
2Productivity
If the system prioritizes voice commands from a primary screen, then command processing becomes efficient, but commands from secondary screen users may be delayed or ignored
Solution Approach 1:
The patent implements dynamic priority adjustment based on screen type and command context. The primary screen maintains higher priority for time-critical commands (e.g., navigation, safety), while the secondary screen handles less time-sensitive commands (e.g., entertainment, climate control). This dynamic approach ensures efficient processing of critical commands while reliably responding to secondary commands, resolving the contradiction between efficiency and reliability.
3Loss of information
If the system displays interaction identifiers on the primary screen to indicate secondary user interactions, then users are informed of multiple interactions, but the primary screen becomes cluttered
Solution Approach 1:
The patent extracts the detailed interaction information from the primary screen and displays it separately on the secondary screen. The primary screen shows only essential status indicators, while the secondary screen displays comprehensive interaction details including user identity, command content, and interaction state. This extraction approach informs users of multiple interactions without cluttering the primary screen.
4Measurement precision
If the system uses sound source positioning to determine user location, then screen assignment becomes accurate, but the system complexity increases
Solution Approach 1:
The patent leverages the existing sound source positioning technology already present in modern vehicles for other functions (e.g., noise cancellation, ambient sound monitoring) and applies it to voice interaction screen assignment. This multi-functional use of the sound positioning system enables accurate user location detection without adding dedicated hardware or increasing overall system complexity.

AI summary
This specification relates to the field of voice interaction technologies, is applied to the fields of intelligent vehicles, internet of vehicles, mobile terminals, and the like, and discloses a voice interaction method, a device, and a storage medium. The voice interaction method includes: when detecting a first voice command of a first user, first determining a screen corresponding to the first user, for example, a first screen, and then determining the first screen as a primary voice screen, and displaying a first voice interaction interface through the first screen; and in a process in which a vehicle-mounted device receives the first voice command, if detecting a second voice command issued by a second user, and determining a screen corresponding to the second user as another screen, for example, a second screen, determining the second screen as a secondary voice screen, displaying a second voice interaction interface through the second screen, and displaying, through the first screen, an interaction identifier indicating that there is another interacting user. Based on the foregoing solution, an advantage of a plurality of screens can be leveraged, multi-screen human-machine interaction can be implemented, and user experience can be effectively improved.
