Vehicle Voice Input Screen Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, voice input systems often interfere with manual input methods, and the shared screen space leads to display issues, causing disruptions and user frustration, especially when switching between modalities.
Innovation Solution
A method and device that activate a special manual operation mode when an object is detected near the display, hiding voice input operating instructions to allow uninterrupted manual input, and automatically resume voice input when the object is no longer detected, enabling seamless multimodal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice input operating instructions are displayed on the screen, then first-time users can understand voice commands better, but manual input is impeded by the displayed instructions
Solution Approach 1:
The operating instructions are dynamically displayed or hidden based on the detected input mode. When manual input mode is detected (object near display), the instructions are hidden to provide full screen area. When voice input mode is active, the instructions are displayed to assist users. This dynamic adaptation resolves the contradiction by making the screen layout flexible rather than static.
Solution Approach 2:
The system preliminarily detects the presence of an object near the display using a proximity sensor before manual input begins. This preliminary detection triggers the hiding of voice input instructions in advance, ensuring that the full screen area is immediately available for manual input operations without any overlap or interference.
2Adaptability or versatility
If voice input mode is active, then information can be entered by speech, but manual input is disrupted by the active voice dialog
Solution Approach 1:
The system dynamically switches between voice input and manual input modes based on real-time proximity detection. When an object approaches the display, the system automatically transitions from voice input mode to manual input mode, allowing users to seamlessly switch input methods without disruption or interruption of the active dialog.
Solution Approach 2:
A proximity sensor acts as an intermediary between the user's hand and the system's input mode detection. The sensor detects the presence of an object near the display and triggers the mode switch, serving as a mediator that enables smooth transitions between voice and manual input without requiring explicit user commands or causing disruption.
3Device complexity
If the same screen is shared by both voice input and manual input modes, then device complexity is reduced, but display information becomes problematic
Solution Approach 1:
The system preliminarily hides the voice input operating instructions before manual input begins, ensuring that only relevant information is displayed at any given time. This preliminary action prevents information overload and maintains display clarity while still providing comprehensive functionality for both input modes.
Solution Approach 2:
The display presents different information quality based on the active input mode. When manual input is detected, the display shows full-screen input fields with no voice instructions. When voice input is active, the display shows voice operating instructions. This local adaptation of display content to the current input mode maintains information clarity while preserving a single unified screen.

AI summary
The method involves inputting information in a device of a vehicle and activating a non-speech input mode by an operating element for inputting manual information. An object is detected in a surrounding area of the operating element. A non-speech input mode is deactivated if no object is detected in the surrounding area of the operating element. An independent claim is also included for an apparatus for input speech to a vehicle.
