Recognition Of Polish Sign Gesture Language In Extended Reality

This paper presents a system for recognizing static gestures of Polish Sign Language (PJM) in Extended Reality (XR) using hand tracking. Developed in Unity3D with the XR Hands package and OpenXR, it employs a heuristic rule-based approach for real-time recognition without external machine learning models. The system was tested on Meta Quest 3 and validated on Meta Quest 2, demonstrating high accuracy under varying conditions. Results confirm the feasibility of XR-based sign language recognition, with potential applications in accessibility and education.
