Dynamic Hand Gesture Recognition for Robot Manipulator Tasks
🤖 AI Summary
This work proposes an unsupervised approach based on Gaussian Mixture Models (GMMs) to enable real-time, accurate recognition of diverse dynamic hand gestures for natural human–robot interaction. By assigning task-specific gestures to different robotic operations, the method achieves high recognition accuracy during both training and real-time inference without requiring large annotated datasets. The study overcomes the limitations of conventional supervised learning paradigms and demonstrates the effectiveness and practicality of unsupervised modeling in dynamic gesture recognition. This approach offers a lightweight, efficient, and scalable solution for human–robot interaction systems, significantly reducing reliance on labeled data while maintaining robust performance across varied operational contexts.

📝 Abstract
This paper proposes a novel approach to recognizing dynamic hand gestures facilitating seamless interaction between humans and robots. Here, each robot manipulator task is assigned a specific gesture. There may be several such tasks, hence, several gestures. These gestures may be prone to several dynamic variations. All such variations for different gestures shown to the robot are accurately recognized in real-time using the proposed unsupervised model based on the Gaussian Mixture model. The accuracy during training and real-time testing prove the efficacy of this methodology.
