Abstract
— Advancements in Embodied Virtual Reality (EVR) can revolutionise motor learning and rehabilitation by offering immersive and ecologically valid environments. This study refines an EVR setup to investigate motor learning using a realistic yet controlled billiards task. The setup integrates physical interactions with virtual experiences , allowing participants to use real-world objects, including a cue stick and balls. Enhancements include a redesigned pool table to control task difficulty, refined virtual ball velocity profiles for more realistic dynamics, and novel feedback mechanisms that isolate error-based and reward-based learning. Pilot studies with naive and moderately experienced pool players demonstrated increased realism, engagement, and experimental control. The system supports the study of adap-tive skill acquisition in naturalistic contexts, addressing the challenges of balancing experimental control with real-world applicability. The improved EVR setup provides a powerful tool for studying motor learning and translating laboratory insights into real-world neurorehabilitation applications, supporting adaptive skill acquisition in naturalistic settings. Clinical relevance — The motor learning insights from the EVR setup hold significant implications for neurorehabilitation, providing a robust platform to design adaptive and engaging rehabilitation programs for conditions like stroke recovery and motor impairments, fostering skill relearning in controlled yet naturalistic settings.
