VirgoMotion
Many features are still experimental and breaking changes may occur.
What is VirgoMotion?
A lightweight motion-capture and streaming tool driven only by your iPhone camera. You don't need gloves or a mocap suit — just mount your iPhone on top of your display, and it captures your pose, facial expression, and even finger movements. The PC-side studio app then drives a character and renders the result for streaming.
We made this because we want to see more emotionally expressive, charming VTubers in everyday streams.
Highlights
- Camera-only mocap — With one (or two) iPhones, you can drive the upper body, facial expression, and fingers.
- Streaming studio included — Switch characters, backgrounds, lights, and cameras on the fly, and pipe the output straight to OBS.
- Fully customizable — Combine it with the LiveStudio SDK to build your own dedicated streaming application from the ground up.
System Requirements
Required
- Windows PC
- iPhone X or later
- A holder to mount the iPhone
Recommended
- iPhone cooler (helps during long streams to manage heat)
- A holder that mounts the iPhone on top of your display (so your gaze stays natural)
Application Layout
VirgoMotion consists of three apps.
- Capture app (iPhone) — Analyzes pose and expression from the camera feed and sends them to the PC.
- Studio app (PC) — Drives the character based on the incoming data and renders the video for streaming.
- Remote app (PC) — Connects to the Studio app to switch live scenes and operate parameters.
- Fusion app (PC) — Receives motion data from one or more capture apps, merges it, and forwards it to the Studio app. Acts as the relay point in multi-iPhone setups such as the dual-camera configuration.
How to Navigate the Docs
