Zusammenfassung
Virtual reality (VR) offers immersive experiences by extending beyond real-world capabilities. Typically, users’ real-world hand movements are directly mapped to their virtual hands. However, it can be beneficial to redirect users’ hands by displaying virtual hands at different positions. Noticeable redirection can disrupt immersion, making understanding detection thresholds essential. This study investigates how virtual hand models with different levels of realism in terms of appearance and dexterity affect redirection sensitivity with a gain based redirection method. Twenty-nine participants performed reaching tasks in a virtual environment with varying redirection amounts using four hand models. We found significant differences in the sense of embodiment across hand models. However, detection thresholds for redirection sensitivity did not vary significantly between hand models.
