Redirected walking enables users to explore virtual environments larger than the physical space by introducing subtle deviations between virtual and physical movement. Dynamic gains have been shown to extend detection thresholds for various redirection gains. However, the effects of different gain change modes on detection thresholds for translation gain, as well as the influence of factors, remain insufficiently understood. A psychophysical experiment with 46 participants was conducted to examine the effects across four gain change modes (sudden, gradual, quadratic, and constant) while considering gender, VR familiarity, and gain direction. Participants completed two-alternative forced choice tasks to judge discrepancies between virtual and physical walking. Detection thresholds were determined using a staircase method. Results indicate that gradual gain change is more difficult to detect than sudden gain change, while differences among the other modes are not statistically significant. Furthermore, gender, gain direction, and VR experience were found to significantly influence detection thresholds.
