# 15 Years of Research on Redirected Walking in Immersive Virtual Environments > ## Abstract ## Abstract > users wearing head-mounted displays can experience the illusion of walking in any direction for infinite distance while, in reality, they are walking a curvilinear path in physical space. This is accomplished by introducing unnoticeable rotations to the virtual environment-a technique called [redirected walking](https://wiki.g15e.com/pages/Redirected%20walking.txt). This paper gives an overview of the research that has been performed since redirected walking was first practically demonstrated 15 years ago. https://ieeexplore.ieee.org/document/8255772
