An Immersive Hazelnut Tree Pruning Simulator for Agricultural Operator Training

The agricultural sector faces significant challenges in workforce training due to labor shortages, high costs, and seasonal constraints. To address these issues, this study presents the design and evaluation of an immersive hazelnut pruning simulator developed within the DEMETRA research project. The simulator leverages Virtual Reality (VR) and mechatronics to provide an interactive and realistic training environment for agricultural operators. Using high-fidelity 3D reconstructions created through photogrammetry and laser scanning, the system offers an engaging and lifelike experience. Key features include a step-by-step virtual instructor, realistic pruning tool interactions, full-body motion reconstruction for enhanced immersion, and markerless Human Pose Estimation (HPE) for ergonomic studies. The system also incorporates branch-cutting mechanics and an omnidirectional treadmill for unrestricted movement. Preliminary evaluations highlight the potential of this technology to improve skill acquisition and training efficiency in agriculture, offering a scalable solution for operator education.
