Viso FBT, developed by RoarWild Studio, is a mobile app that enables full-body tracking (FBT) in VR using only a smartphone. By using the phone’s camera, it captures body movement and translates it into a VR avatar in real time. The app is designed primarily for VRChat users who want a more accessible way to experience full-body presence without dedicated trackers.

Camera-based tracking and setup experience

Viso FBT uses the smartphone camera to track body movement from the elbows down to the feet and map it onto a virtual avatar in real time. This allows users to animate their full body in VR without additional hardware.

To get started, the phone needs to be positioned so the entire body is visible, typically using a tripod or stable surface. Once set up, users can begin tracking with minimal configuration. The app is particularly suited for social VR experiences like VRChat, where full-body movement enhances interaction.

Compatibility and requirements

In terms of platform support, Viso FBT works with VRChat on both Meta Quest and SteamVR on PC. It is free to use and enables full-body tracking using only a smartphone camera. To achieve the best results, users should have a well-lit environment and a clear, unobstructed view of the body. Even with proper setup, tracking performance may vary depending on camera quality, device capability, and overall conditions.

The developers are actively working to improve the app, with ongoing updates focused on enhancing tracking accuracy and reducing latency, as well as expanding support for additional games.

Accessible full-body tracking for VR

For VRChat users and Quest owners who prefer not to invest in external trackers, Viso FBT offers a practical way to experience full-body tracking using only a smartphone. It integrates smoothly into existing VR setups and continues to improve through ongoing updates focused on accuracy and overall performance.
