Step by Step: Design and Implementation of an Omnidirectional Treadmill for XR Locomotion

Abstract

This thesis explores the development of an omnidirectional treadmill for enhancing movement within virtual reality (VR) environments. Traditional VR movement methods, like joystick navigation or teleportation, often lead to motion sickness or reduced immersion due to their unnatural mechanics. The omnidirectional treadmill presents a promising solution by allowing natural, 360-degree movement without the spatial constraints of the physical world. This thesis explores existing commercial solutions, including the Virtuix Omni and Infinadeck, and attempts to replicate a novel design inspired by Disney's Holotile technology. This new design utilizes motorized cones to move a user in 360 degrees, enabling the capability to keep them centered on the treadmill while they walk, thereby enhancing the VR experience while maintaining a compact and flexible system. The thesis details the design process, challenges, and iterative improvements of the treadmill and accompanying software.
