Hand Gesture Recognition for Immersive AR Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual and augmented reality systems require dedicated hardware for user interaction, which can disrupt the immersive experience by necessitating the carrying or locating of external devices.
Innovation Solution
A system that detects the shape of a user's hand and generates interactive features on physical objects within the virtual or augmented reality environment, allowing users to interact without dedicated hardware by recognizing hand gestures and movements, such as drawing motions or tapping, to initiate actions within the virtual space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dedicated hardware or electronic input devices are used for user interaction, then user input capability is improved, but user experience is degraded due to disruption from carrying or locating external devices
Solution Approach 1:
The patent extracts the interaction capability from dedicated hardware devices and relocates it to the user's natural hand gestures. The system detects hand shapes and gestures directly in the environment, removing the need for external controllers, joysticks, or input devices. This extraction resolves the contradiction by maintaining input capability while eliminating device complexity.
Solution Approach 2:
The user's own hand serves as the input device, eliminating the need for external hardware. The system leverages the user's natural anatomy and gestures as the interaction medium, allowing the user to interact with the artificial reality using their body rather than external tools. This self-service approach resolves the contradiction by making the user themselves the input device.
2Device complexity
If hand gesture detection is implemented, then dedicated hardware is eliminated, but detection precision requirements increase
Solution Approach 1:
The system performs preliminary actions by establishing a library of hand templates and gesture patterns before actual interaction. These pre-defined templates serve as reference models that the detection system can compare against real-time hand gestures. This preliminary preparation reduces the real-time detection precision requirements by providing predetermined patterns to match against.
Solution Approach 2:
The system transforms the detection problem by changing parameters from detecting every detail of hand geometry to recognizing key gesture patterns and shapes. By focusing on essential gesture parameters rather than complete hand geometry, the system reduces detection precision requirements while maintaining accurate gesture recognition. The template matching approach allows for parameter abstraction and generalization.
