Redirected walking techniques enable users to naturally locomote in virtual environments (VEs) that are larger than the tracked space. Redirected walking imperceptibly transforms the VE around the user with predefined estimated threshold gains. Previously estimated gains were evaluated with a 40° field of view (FOV). We conducted a within-participant user study to estimate and compare thresholds for rotation gains. Significant differences in detection thresholds were found between FOVs. When using a 110° FOV, rotations can be decreased 31% and increased 49% compared to decreased 18% and increased 47% with a 40° FOV. Significant differences were found between female and male gains with a 110° FOV.
