Abstract
Virtual Reality (VR) is an immersive technology that enables users to interact with three-dimensional digital environments through headsets and controllers. Among its primary goals are to enhance immersion and presence, but several challenges can compromise the experience or even render it unusable. Key issues include motion sickness, device discomfort, immersive locomotion, user safety and affordability. In particular, as VR becomes more accessible for home use, locomotion presents a significant challenge. Users often lose awareness of their real world surroundings, making real walking in VR unsafe. To address this, various locomotion techniques have been developed, including joystick-based movement, teleportation, arm-swinging techniques, and seated locomotion techniques.
Each one of these techniques has its own strengths and weaknesses: Joystick-based movement is intuitive but can induce motion sickness, while teleportation reduces discomfort but disrupts immersion
