Vehicle Gesture Interface With Display-Plane Indicator Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user-vehicle interfaces, particularly those using gesture control, face challenges in providing intuitive and precise interaction with content on displays, as users struggle to understand the virtual distance of their gestures from the interaction plane, leading to difficulty in accurately navigating and interacting with vehicle controls.
Innovation Solution
A gesture control system that senses user gestures to control the location of an indicator on a display, ensuring it moves in accordance with the gesture direction and resides in the same plane as the content, allowing for intuitive and precise interaction by aligning the indicator with the user's perspective and providing optional scaling factors for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture control is used to interact with display content, then ease of operation is improved, but measurement precision deteriorates because users cannot accurately judge the virtual distance of gestures from the interaction plane
Solution Approach 1:
A visual indicator is introduced as an intermediary element that represents the user's gesture position on the display plane. The indicator acts as a mediator between the physical gesture in 3D space and the 2D display interaction, providing visual feedback that helps users accurately understand their gesture's position and distance relationship with the display content.
Solution Approach 2:
The system provides visual feedback by displaying an indicator that moves in response to user gestures. This feedback loop allows users to see the immediate effect of their gestures on the indicator position, enabling them to adjust their gesture magnitude and direction to achieve precise interaction with display content.
2Ease of operation
If the indicator moves continuously with gesture direction, then ease of operation is improved, but device complexity increases due to scaling factor calculations and coordinate transformations
Solution Approach 1:
The system dynamically adjusts the scaling factor parameter based on the detected gesture magnitude and direction. By changing this parameter, the system can adapt the indicator's movement range and speed to match the user's gesture intensity, providing a more natural and intuitive interaction experience while managing computational complexity through parameter optimization.
3Adaptability or versatility
If gesture control supports multiple vehicle types and conditions, then adaptability is improved, but device complexity increases due to customization requirements
Solution Approach 1:
The gesture control system is designed with universal functionality that can adapt to different vehicle types and usage conditions. By implementing a core gesture recognition engine that works across various contexts, the system achieves multi-functionality without requiring separate specialized systems for each vehicle type, thereby managing complexity while maintaining versatility.
