Solution Overview
Problem
Current driver assistance systems face challenges in reducing the complexity and duration of control actions, necessitating more efficient and intuitive man-machine interfaces that can integrate multiple input modalities to enhance user interaction.
Innovation Solution
A method and system architecture for multimode information input and display adaptation in vehicles, utilizing touch, gesture, and voice recognition to enable seamless interaction, where touch and gesture inputs activate voice recognition, restricting vocabulary based on selected objects, and allowing voice commands to be inputted for intuitive control, with adaptive display optimization based on user intent and context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple alternative communication modalities (voice, manual input) are provided for controlling driver assistance functions, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple input modalities (voice recognition, touch input, gesture recognition) into a single integrated user interface system. The control device merges these different communication channels to work synergistically, allowing users to switch between or combine modalities seamlessly, thereby improving ease of operation while managing complexity through unified architecture
Solution Approach 2:
The user interface is designed with universal capabilities to handle multiple types of input (voice commands, touch gestures, hand movements) through a single system. This multi-functional design allows the same interface to adapt to different user preferences and situations, enhancing ease of operation without requiring separate dedicated systems for each modality
2Adaptability or versatility
If the user interface integrates multiple driver information and driver assistance functions, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The user interface employs dynamic adaptation mechanisms that automatically adjust the available input modalities and interface behavior based on the current driving situation, selected function, and detected user intent. This dynamic reconfiguration allows the system to optimize for specific tasks (e.g., prioritizing voice input during complex navigation) while maintaining a manageable base complexity through modular architecture
Solution Approach 2:
The system architecture is segmented into modular components, with each input modality (voice, touch, gesture) processed through separate but coordinated modules. This segmentation allows the system to integrate multiple functions and adapt to different scenarios by activating only the necessary modules, thereby improving adaptability while controlling overall complexity
3Measurement precision
If the vocabulary for voice interaction is restricted based on the selected object, then the measurement precision is improved, but the ease of operation worsens
Solution Approach 1:
The system performs preliminary actions by automatically selecting and restricting the voice vocabulary based on the currently selected object or function before the user issues a voice command. This pre-filtering of available commands based on context improves precision by eliminating irrelevant options, while the seamless automatic adaptation maintains ease of operation by requiring no additional user effort to configure the vocabulary

AI summary
In a method for multimode information input and/or adaptation of the display of a display and control device, input signals of different modality are detected which are supplied via the device to a voice recognition unit, thus initiating a desired function and/or display as an output signal, which are displayed on the device and/or output by voice output. Touch and/or gesture input signals are provided on or to the device for selection of an object intended for interaction and activation of the voice recognition unit and for the vocabulary which is provided for interaction to be restricted with the selection of the object and/or activation of the voice recognition unit as a function of the selected object, on the basis of which a voice command from the restricted vocabulary is added to the selected object as an information input and/or for adaptation of the display, via the voice recognition unit.
