Gesture Control via Depth Values for Vehicle Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of electronic devices in mobile vehicles requires drivers to divert their attention, compromising driving safety as they need to operate multiple devices simultaneously, leading to potential safety hazards.
Innovation Solution
A gesture operation method based on depth values using stereoscopic images, where a processing unit recognizes triggering and command gestures within the images to perform corresponding operations, allowing for hands-free control of vehicle systems without requiring drivers to look away from the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices are installed in the mobile vehicle, then the functionality and versatility of the vehicle is improved, but the driver's attention is diverted and driving safety deteriorates
Solution Approach 1:
The patent replaces manual mechanical operation (touching, clicking, or verbally commanding devices) with a gesture-based control system. The gesture recognition system captures hand movements via camera, processes them through algorithms to identify specific gestures, and executes corresponding device commands, thereby substituting the mechanical interaction chain with an optical recognition and digital execution system that keeps the driver's hands on the wheel and eyes on the road
Solution Approach 2:
The patent introduces a gesture recognition system as an intermediary between the driver and the electronic devices. This intermediary translates physical hand gestures into device control commands without requiring direct interaction with the devices themselves, serving as a safe mediation layer that maintains driving focus while enabling device operation
2Ease of operation
If a touch screen is used to operate integrated devices, then the ease of operation is improved, but the driver needs to move sight away from the road and driving safety deteriorates
Solution Approach 1:
The patent replaces the visual-mechanical interaction of touch screen operation with a gesture-based optical recognition system. Instead of requiring the driver to look at and physically touch a screen, the system captures hand gestures through a camera, processes them algorithmically, and executes commands, substituting the sight-and-touch mechanism with a hands-free, eyes-on-road gesture recognition mechanism
Solution Approach 2:
The patent creates a virtual copy of the interaction interface through gesture recognition. Rather than requiring direct contact with the physical touch screen, the system recognizes hand gestures in space and translates them into equivalent control commands, effectively creating a virtual interaction layer that replicates device control functionality without requiring visual attention or physical contact with the screen

AI summary
A gesture operation method based on depth values and the system thereof are revealed. A stereoscopic-image camera module acquires a first stereoscopic image. Then an algorithm is performed to judge if the first stereoscopic image includes a triggering gesture. Then the stereoscopic-image camera module acquires a second stereoscopic image. Another algorithm is performed to judge if the second stereoscopic image includes a command gesture for performing the corresponding operation of the command gesture.
