Vehicle Input Guidance for Multi-Modal Control Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face overwhelming complexity when choosing between different operating modalities for vehicle devices, such as keyboards, gestures, and voice control, leading to increased learning time and confusion due to the need to understand multiple input methods for specific system responses.
Innovation Solution
A method and operating system that detect operable functions and determine preferred operating action types based on current device states, providing output that highlights suitable input modalities and actions, allowing users to easily recognize and use appropriate inputs by displaying operable functions and preferred action types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operating modalities are provided for device control, then system versatility and adaptability are improved, but user confusion and learning time increase
Solution Approach 1:
The system dynamically adapts the user interface by detecting the current operating modality and automatically adjusting displayed controls and options to match the selected input method. When a user chooses gesture control, the system highlights gesture-based operations and dimms keyboard options, creating a dynamic interface that evolves based on user preferences and contextual information about the device state.
Solution Approach 2:
Different regions or aspects of the user interface are optimized for specific operating modalities. The system applies modality-specific enhancements to relevant controls while maintaining other options in a subdued state. For example, when voice control is detected, voice-activated commands receive prominent display with enhanced visual feedback, while physical button controls remain visible but less emphasized.
2Adaptability or versatility
If comprehensive operating options are displayed to users, then system functionality is improved, but information overload occurs
Solution Approach 1:
The user interface is segmented into modality-specific zones or sections. When gesture control is detected, the interface divides into gesture instruction areas, gesture-sensitive zones, and secondary control areas. This segmentation allows the system to present comprehensive functionality while organizing information into manageable, modality-appropriate groups that reduce cognitive load.
Solution Approach 2:
The system selectively emphasizes or suppresses specific operating options based on the detected modality rather than displaying all options equally. When keyboard input is detected, text-based controls are fully visible and interactive, while gesture controls are shown in a minimized or informational-only state. This partial display strategy provides comprehensive functionality without overwhelming the user with simultaneous presentation of all modalities.

AI summary
In the method according to the invention for detecting a user input for a device of a vehicle, an operable function of the device is detected and a first and a second potential operational action type are determined depending on the operable function. A preferred operational action type is determined and an output is generated and output depending on the preferred operational action type. The output comprises an operating object, on the basis of which the preferred operational action type is displayed to the user. The operating system for detecting a user input for a device of a vehicle comprises a control unit (8) and an output unit (3), which is coupled to the control unit (8). The control unit (8) is designed to detect an operable function of the operating system, to determine a first and a second potential operational action type for the operable function depending on the operable function, and to determine a preferred operational action type. The control unit (8) is also designed to generate an output depending on the preferred operational action type and to output the output by means of the output unit (3). The output comprises an operating object, on the basis of which the preferred operational action type is displayed to a user.
