Light-Based Gesture Controls for Vehicle Steering Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems on steering wheels and dashboards require manual interaction with buttons and touch screens, which can be cumbersome and distract drivers, especially when controlling entertainment and navigation systems while driving.
Innovation Solution
A sensor system integrated into the steering wheel and dashboard that detects position, proximity, and pressure to enable complex gestures, allowing drivers to control entertainment and navigation systems through hand slide, wave, and tap gestures without physically interacting with buttons, using light emitters and detectors to interpret these gestures and project relevant interfaces onto a head-up display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual buttons and touch screens are used on steering wheel and dashboard, then control functionality is provided, but driver distraction and operational complexity increase
Solution Approach 1:
The patent replaces mechanical buttons and touch screens with a light-based optical sensing system. Light emitters project invisible light fields across the steering wheel and dashboard surfaces, while light detectors capture reflected light patterns to identify hand gestures. This substitution eliminates the need for physical contact with controls, allowing drivers to operate vehicle systems through natural hand movements in the air, thereby reducing distraction and operational complexity
Solution Approach 2:
The patent introduces light fields as an intermediary between the driver and the vehicle's control systems. Invisible light beams are projected onto control surfaces, and hand gestures interact with these light fields to generate control signals. This intermediary layer enables intuitive gesture recognition without requiring direct mechanical interaction, improving ease of operation while minimizing driver attention demands
2Adaptability or versatility
If physical buttons and controls are mounted on steering wheel and dashboard, then control functions are available, but dashboard clutter and device complexity increase
Solution Approach 1:
The patent extracts the control functionality from physical buttons and mounts it virtually on the steering wheel and dashboard surfaces through light projection. The actual control interfaces are removed as physical components, replaced by invisible light fields that define control zones and gesture recognition areas. This extraction eliminates dashboard clutter while preserving full control functionality through gesture-based interaction
Solution Approach 2:
The light-based control system provides universal functionality across multiple surfaces (steering wheel rim, spokes, dashboard). The same optical sensing infrastructure supports various control modes including volume adjustment, track selection, temperature control, and menu navigation through different hand gestures. This multi-functional approach replaces numerous specialized physical buttons with a single versatile gesture recognition system
