Vehicle Voice Assistant State Display Using Light Band Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice assistance systems for motor vehicles struggle to effectively communicate their state to drivers without distracting them from the road, particularly in displaying readiness to receive voice commands or other system states.
Innovation Solution
A method and system that utilize a light band with specific light characteristics and a display device to visually represent the state of a voice assistance system, allowing for easy differentiation and recognition of system states without requiring the driver to focus on a display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display device is used to show voice assistance system state, then information completeness is improved, but driver distraction increases
Solution Approach 1:
The feedback representation is segmented into two distinct channels: a light band providing peripheral visual cues and a display device providing detailed state information. This segmentation allows the driver to receive comprehensive state information while minimizing distraction by using the light band for quick, peripheral awareness and the display device for detailed information only when needed.
Solution Approach 2:
Different types of visual feedback are assigned to different locations with different attention requirements. The light band, positioned for peripheral vision, provides simple state indicators that can be perceived without focused attention. The display device, requiring focused attention, provides comprehensive state details. This local quality differentiation ensures information is delivered according to the attentional demands of each display location.
2Object-affected harmful factors
If a light band is used to indicate system state, then driver distraction is reduced, but state differentiation capability is limited
Solution Approach 1:
The system merges two different feedback mechanisms into a unified state representation system. The light band provides quick, peripheral-visible state indicators with simple visual characteristics, while the display device provides detailed, comprehensive state information. Together, these merged feedback channels achieve both low distraction (from the light band) and high state differentiation capability (from the combined system).

AI summary
Technologies and techniques for displaying a specific state of a voice assistance system for performing a voice assistance function for a motor vehicle. A light strip is provided for providing a specific light distribution, wherein a specific light characteristic of the light strip is associated with the specific state of the voice assistance system, wherein, when the voice assistance system exhibits the specific state, the light strip displays the specific light distribution according to the associated light characteristic, wherein a specific feedback display is associated with the specific state of the voice assistance system, and, when the voice assistance system exhibits the specific state, the specific feedback display is additionally displayed on a display device that is distinct from the light strip.
