Vehicle Gesture Interface With Plane-Aligned Display Indicator
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 display content due to the visualisation of user appendages floating in the display, making it difficult for users to understand how to interact with content effectively.
Innovation Solution
A gesture control system that senses the direction of a user's gesture and controls an indicator on the display in the same plane as the content, allowing intuitive and precise interaction by aligning the indicator's movement with the sensed direction, optionally with additional representations to guide the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gesture control systems visualise user appendages in the display, then interaction capability is provided, but user understanding of how to interact with content is reduced
Solution Approach 1:
The patent introduces an intermediary indicator that acts as a mediator between the user's gesture and the display content. Instead of directly visualizing the appendage or requiring direct interaction, the indicator serves as a visual cue that responds to gesture direction, making the interaction mechanism understandable while maintaining versatility
Solution Approach 2:
The patent replaces traditional mechanical or direct visual feedback mechanisms with a computational indicator system. The indicator is controlled by processing gesture direction data, substituting physical appendage visualization with a software-based visual cue that provides clearer interaction guidance
2Reliability
If traditional physical actuators are used, then simplicity and robustness are achieved, but interaction scope is limited
Solution Approach 1:
The patent implements a gesture control system that can interact with various types of display content (media player, navigation, communication, etc.), making the interface universal across different vehicle functions. The same gesture sensing mechanism serves multiple interaction purposes, expanding scope while maintaining reliability through proven sensor technology
3Adaptability or versatility
If gesture control is implemented without plane-aligned indicator, then gesture sensing capability is provided, but interaction precision is reduced
Solution Approach 1:
The patent aligns the indicator with the display plane, adding a dimensional constraint to the gesture control. By projecting or positioning the indicator within the two-dimensional display plane rather than in three-dimensional space, the system achieves precise content selection while maintaining full gesture sensing capability
Solution Approach 2:
The patent creates a two-dimensional representation (copy) of the gesture direction within the display plane. The indicator copies the essential directional information from the three-dimensional gesture into the two-dimensional display space, enabling precise interaction without requiring full spatial visualization
