Optimized Sensor Position Detection: Improving Visual Sensor Setups for Hand Tracking in VR

Hand tracking plays an important role in many Virtual Reality (VR) applications, enabling natural user interactions. Achieving precise tracking is often challenged by occlusion and suboptimal sensor placement. To address these challenges, we developed the Sensor Positioning Simulator, a versatile tool designed to optimize sensor placement. To demonstrate its utility, we simulated scenes from the VIRTOSHA project, a VR-based surgical training platform. Evaluations show that the tool effectively positioned sensors to achieve maximum hand surface visibility and full hand movement area coverage, even in occlusion-heavy environments. Future developments include support for animated simulations and validation through real-world experiments.
