Vehicle Gesture Control Interface with Visual 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 content on displays, as users struggle to understand the virtual distance of their gestures from the interaction plane, leading to difficulties in accurately navigating and interacting with vehicle controls.
Innovation Solution
A gesture control system that senses the direction of user gestures and controls a location indicator on the display to move in accordance with the sensed direction, with the indicator positioned in the same plane as the content, allowing for intuitive and precise interaction by aligning the indicator with the user's gesture and applying scaling factors to enhance 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. The indicator acts as a mediator between the physical gesture in 3D space and the 2D display plane, providing visual feedback that helps users understand the relationship between their hand position and the interaction target, thereby improving measurement precision without sacrificing gesture control ease
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 effect of their gestures in real-time and adjust their hand position accordingly, improving the precision of gesture-to-display mapping while maintaining the intuitive nature of gesture control
2Ease of operation
If the indicator is positioned in the same plane as the content, then ease of operation is improved through intuitive interaction, but device complexity increases due to additional processing requirements
Solution Approach 1:
The system creates a 2D representation (copy) of the user's 3D gesture position on the display plane. Instead of complex 3D rendering, a simplified indicator copy is generated that mirrors the gesture's intended target position, providing intuitive visual feedback while avoiding the computational complexity of full 3D graphics processing

AI summary
There is provided a user-vehicle interface, comprising: a selection system, arranged to receive an input from a user of the vehicle, the selection system being arranged to process the input to facilitate interaction with a particular selected region of a display, in accordance with that input; and a gesture control system, arranged to sense a gesture of a user, the gesture control system being arranged to process the sensed gesture to control interaction with content on the display, in accordance with that sensed gesture; wherein the user-vehicle interface is arranged such that the gesture control interaction with content on the display is only allowed for the particular region of the display, as selected by the user.
