In virtual reality environments that allow users to walk freely, the area of the virtual environment (VE) is constrained to the size of the tracking area. By using redirection techniques, this problem can be partially circumvented; one of the techniques involves rotating the user more or less in the virtual world than in the physical world; this technique is referred to as rotational gain. Experiments conducted by Frank Steinicke et al. [7] sought to uncover users' ability to detect the usage of rotational gain. This paper seeks to further investigate this area, examining the effect of visual density in the VE. Testing visual density using 0, 4 and 16 objects did not seem to reveal the point at which the test participants become noticeably affected.
