Agent Device Loudness-Based Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agent technologies in vehicles lack user-friendliness, as they do not effectively adapt to varying vocal input loudness, leading to inconsistent and sometimes intrusive agent interactions.
Innovation Solution
An agent device and system that utilize a display controller and controller to dynamically adjust the display of an agent image based on vocal input loudness, allowing for private or public realization of the agent service, ensuring user intention is reflected and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the agent image is always displayed on the first display, then the agent service is always visible to all users, but this may be intrusive when the user intends private interaction
Solution Approach 1:
The patent applies dynamics by making the agent image display adaptive rather than static. The controller dynamically switches between displaying the agent image on the first display (public mode) and the second display (private mode) based on the detected loudness of the user's voice. When soft speech is detected, the system transitions to private mode, displaying the agent image only on the user's terminal device, thereby reducing intrusiveness while maintaining service availability.
2Adaptability or versatility
If the agent image is displayed on the second display when voice loudness is low, then private interaction is supported, but the agent image may not be visible to other users who need to see it
Solution Approach 1:
The patent applies segmentation by dividing the display function across multiple devices. The first display (in-vehicle display) serves public visibility needs, while the second display (terminal device display) serves private interaction needs. The controller segments the agent image display based on voice loudness detection, routing it to appropriate displays, thus supporting both private interaction and public visibility without information loss.
3Measurement precision
If the system detects voice loudness to control display, then user intention is accurately reflected, but the system complexity increases
Solution Approach 1:
The patent applies feedback by implementing a closed-loop control system. The voice recognition device continuously monitors the user's voice loudness, and the controller uses this feedback to automatically adjust the agent image display mode. This feedback mechanism enables accurate detection of user intention (soft speech indicating private interaction desire) while managing system complexity through automated control logic rather than manual intervention.

AI summary
An agent device includes a display controller configured to cause a first display to display an agent image when an agent providing a service including causing an output device to output response of voice in response to an utterance of a user is activated, and a controller configured to execute particular control for causing a second display to display the agent image according to loudness of a voice received by an external terminal receiving a vocal input.
