Gesture-Control Vehicle Display Interface With In-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 distance of virtual hand movements from the content plane, leading to difficulty in accurately interacting with virtual elements.
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, providing continuous and proportional movement, and optionally using scaling factors or offset positioning to enhance interaction accuracy.
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 distance of virtual hand movements from the content plane
Solution Approach 1:
The patent introduces an intermediary visual indicator that represents the user's hand position and movement direction on the display. This indicator acts as a mediator between the user's physical gesture and the content plane, providing visual feedback about distance and position without requiring the user to directly judge the abstract virtual hand position. The indicator translates complex spatial relationships into simple visual cues that are easy to interpret.
Solution Approach 2:
The system provides continuous visual feedback through the indicator that shows the user's current gesture position, movement direction, and proximity to the content plane. This feedback loop allows users to adjust their gestures in real-time to achieve precise interactions, solving the measurement precision problem by making the previously invisible hand position visible and measurable through visual cues.
2Reliability
If traditional physical actuators are used for vehicle control, then reliability is improved, but adaptability deteriorates because the interface cannot be easily tailored to different vehicles and use conditions
Solution Approach 1:
The gesture control system is designed as a universal interface that can be adapted to multiple vehicle types and use conditions. The system detects gestures in three-dimensional space and translates them into context-appropriate commands based on the vehicle's current state and the displayed content, allowing the same hardware to serve multiple functions across different vehicle platforms without requiring physical reconfiguration.
Solution Approach 2:
The interface dynamically adapts to different vehicles and use conditions by adjusting the mapping between gestures and commands based on contextual information. The system can modify its behavior, sensitivity, and response characteristics in real-time to suit different driving conditions, vehicle types, and user preferences, providing both reliability through proven gesture recognition and adaptability through contextual customization.

AI summary
There is provided a user-vehicle interface, comprising a gesture control system that is arranged to: sense a direction of a gesture of a user of the vehicle; and process the sensed gesture to control a location of an indicator on a display in accordance with that sensed direction, such that a location of the indicator is arranged to move in accordance with changes in the sensed direction, the indicator being used to show a current position for user interaction with content on the display, and being in a plane in which that content resides.
