947d Tech Co., Ltd. has officially released “HIROMEIRO,” a system that enables full-body 3D avatar tracking using just a single camera, with no wearable devices required, on September 17, 2026. It supports the VRM format, making full-body tracked streaming possible from home in everyday clothes.

Full-Body Tracking With One Camera, in Everyday Clothes

HIROMEIRO is a tracking system that supports VRM, a widely used 3D avatar format. It requires only a single camera for tracking, with no dedicated suit or sensors to wear, and can recognize movement even in everyday clothes.

For streaming, it also offers a green-screen display and an upper-body-only tracking mode suited to seated positions. It also includes a feature for recording vertical video for short-form clips, making it versatile enough for everything from live streaming to clip and short-video posting.

Includes Privacy Protection and Supports Distributed Processing

The PC tracking app includes a feature that hides the camera’s input feed to help protect the streamer’s identity. Reducing the risk of accidentally showing one’s home or face is a welcome point for streamers.

Additionally, since tracking processing and avatar display are separated, tracking can be run on a separate device to distribute the processing load. Alongside the desktop PC version, the tracking app is also available in an Android version and a Python version for developers.

A Record-and-Playback App Is Also Available

An application that can record and play back tracking results is also provided. Saved motions can be played back at normal speed, and since movements are stored in a data format lighter than video, it could also be useful for reviewing motion or creating assets.

From Development Build to Official Release, What’s Next

HIROMEIRO has been provided as a development build since 2023, with development and operational testing carried out through the streaming activities of the company’s virtual talent, Rinne Hiro. With this official release, it’s now available for anyone to download from the official website.

947d Tech was founded in 2018 and develops robotics technology centered on visual recognition. Attention is also on how the technology, refined through the streaming activities of the company’s own talent, will be expanded going forward.

Editor’s Take

Full-body 3D tracked streaming has long been a high barrier area requiring dedicated equipment and ample space. HIROMEIRO, which can be started with just one camera and everyday clothes, could be the push that gets streamers who have worked mainly with 2D models to move into 3D. Nearly three years of operational testing through the company’s own VTuber’s streams is also reassuring. With streamer-focused features like privacy protection and vertical recording already in place, it will be interesting to see how independent VTubers put it to use.
