Breastfeeding provides essential health benefits for both infants and mothers, yet difficulties with positioning and latching are among the main causes of early cessation. Traditional resources, such as brochures, videos, and mobile apps, offer limited opportunities for hands-on practice with spatial tasks, hindering skill acquisition and confidence. Virtual Reality (VR) offers a promising alternative by delivering immersive, interactive, and safe environments to practice complex tasks. Consumer-level VR, however, relies on one-size-fits-all interaction devices, such as standard controllers or hand tracking, which may lack natural gesture fidelity. While VR-based breastfeeding training has been explored, the impact of input device fidelity on usability, cognitive load, and presence remains largely unknown.
