Evaluation of locomotion with the Virtuix Omni

Omni Shoes


VR designers are constantly trying to make the experience more immersive and more natural. However, fully natural locomotion is very difficult to simulate. A user is limited to walking in the available space within a room, while almost all virtual environments are much larger. Semi-natural locomotion devices and techniques such as treadmills and walking-in-place aim to provide a somewhat natural walking experience while keeping the user in the same physical location. Our prior work showed that the semi-natural Virtusphere device was inferior in many aspects of user experience to both fully natural walking and non-natural gamepad-based navigation. In this project, we examine the Virtuix Omni, a state-of-the-art consumer locomotion device that claims to provide a natural walking and running experience for immersive VR games. Using an existing testbed of locomotion tasks that evaluates a technique's accuracy, speed, game experience, and support for spatial orientation, we compared the Omni to a standard gamepad controller technique and to real walking in a large tracked space. The experiment showed that overall user experience with real walking is still superior to both of the other locomotion techniques.
