Vehicle Access Hand Gesture Control With Camera Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle access and remote control systems, such as bracelets and key fobs, are limited by user interface constraints and require the use of mobile applications with graphical user interfaces, making them inconvenient for hands-full or occupied users.
Innovation Solution
A computer vision-based system that uses existing vehicle cameras and wireless vehicle access system (VAS) devices to recognize hand gesture passwords and commands, allowing for secure and customizable vehicle access and remote control without the need for additional UI controls or mobile applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wireless VAS devices (bracelets, key fobs) are used for vehicle access, then basic passive entry functions can be provided, but user interface limitations prevent advanced control capabilities
Solution Approach 1:
The patent replaces mechanical UI controls (buttons, switches) on wireless VAS devices with a computer vision-based hand gesture recognition system. The vehicle's existing cameras capture hand gestures, and machine learning algorithms interpret these gestures as control commands, eliminating the need for additional mechanical or electronic UI controls on the key fob or bracelet.
Solution Approach 2:
The patent introduces an intermediary system consisting of vehicle cameras and machine learning processing between the user and the vehicle control system. Instead of direct control through device buttons, the user's hand gestures are captured by cameras and translated into control commands through AI processing, enabling advanced controls without adding complexity to the wireless VAS device itself.
2Ease of operation
If mobile applications with graphical user interfaces are used for vehicle control, then advanced control commands can be accessed, but convenience is reduced for users with occupied hands
Solution Approach 1:
The patent replaces the need for mobile applications and touchscreen interfaces with a hands-free hand gesture recognition system. Users can control vehicle functions by making hand gestures in front of the vehicle's cameras, eliminating the need to hold or interact with a mobile device while maintaining advanced control capabilities.
Solution Approach 2:
The system allows users to control vehicle functions autonomously through natural hand gestures without requiring them to manually operate a mobile application interface. The machine learning system automatically recognizes and interprets gestures, providing a more intuitive and hands-free control experience.
3Device complexity
If hand gesture recognition is implemented using existing vehicle cameras, then additional UI controls are avoided, but gesture authentication security must be ensured
Solution Approach 1:
The patent implements a two-stage process where hand gesture passwords are recognized and authenticated before granting access to hand gesture commands. The system first captures and verifies the user's unique hand gesture password sequence, then establishes an authenticated session that enables subsequent hand gesture control commands, ensuring security before allowing vehicle control.
Solution Approach 2:
The system provides feedback by recognizing and verifying hand gesture passwords against stored user profiles before enabling control functionality. The machine learning system compares captured gestures with authenticated patterns, providing security verification feedback that ensures only authorized users can access vehicle control commands.

AI summary
Systems and methods for vehicle access and remote control are provided. One method may include establishing a wireless communication link with a wireless vehicle access system (VAS) device, authenticating the wireless VAS device, recognizing a hand gesture password performed by a user of the authenticated wireless VAS device, authenticating the hand gesture password based on a user profile associated with the authenticated wireless VAS device, recognizing a hand gesture command performed by the user of the authenticated wireless VAS device, and executing a vehicle control command associated with the hand gesture command.
