3teneFT (3tene Face Tracking) is a support app for high-precision facial recognition in the PC app for virtual YouTubers, "3tene." If you have an iPhone X or later, you can use your iPhone's facial recognition feature to capture eye and mouth movement and orientation information and send it to 3tene. This information is then reflected in real time on the body tilt and facial movement of characters (VRM, Live2D models) displayed in 3tene, enabling face tracking that can be controlled. Easily animate your favorite characters with your own facial expressions. How to Use *Network knowledge is required for connection. 1. Connect your iPhone to the same network (router) as your PC (3tene) via WiFi. 2. Enter the IP address numbers (xxx.xxx.xxx.xxx) displayed in the "System" section of 3tene's settings window and tap the connect icon to send the recognition results to 3tene. (Only the recognition results will be sent; camera images will not be sent.) 3. Change the face tracking type in 3tene's avatar adjustment window to "iPhone." 4. When you activate 3tene's face tracking, the facial information recognized by your iPhone will be reflected in your 3tene character. If your security software's firewall is enabled, communication between 3tene and 3teneFT may be blocked. If this happens, you will need to add settings to your security software to prevent 3tene from being blocked.

LAPLACE Persona Tracker turns your iPhone or iPad into a face-tracking camera for LAPLACE Persona, the VTubing app for Mac, Windows and Linux. Point the front camera at yourself and your Live2D or VRM avatar on the desktop follows your expressions, head movement and eyes in real time. HOW IT WORKS • ARKit tracks all 52 facial expression shapes plus head rotation and position, up to 60 times a second. • Tracking streams over your local Wi-Fi network straight to the desktop. No cloud, no account, no internet connection required. • Tap Connect and the app finds LAPLACE Persona on your network. If your network blocks discovery, type the address shown in the desktop's tracking panel instead. • Sit the way you stream and tap Calibrate to make that pose neutral. The app remembers your desktop and your calibration the next time it opens. PRIVACY FIRST • Camera video never leaves the device. Only tracking values are sent, and only to the computer you chose. • The preview draws a wireframe mesh of your face, not the camera feed, so nothing from your room is on screen. • Normalized Face Mesh, on by default, draws your expressions on a generic face instead of your own, for when the phone itself is on camera. • No analytics or advertising. Face tracking runs on your devices. BUILT FOR LONG STREAMS • Save Energy dims the screen and pauses the preview a few seconds after your last touch, while tracking keeps streaming. Tap to wake. • Works in portrait and landscape, on iPhone and iPad. TWO STREAMERS, TWO PHONES The desktop can pin each tracking source to a specific phone, so two people can drive two avatars on one computer. REQUIREMENTS • LAPLACE Persona for Mac, Windows or Linux, available at laplace.live/persona, with a tracking source of type LAPLACE Persona Tracker turned on. • The phone and the computer on the same local network. The app asks for Local Network permission the first time it connects. • iOS 17 or later. Face tracking needs Face ID or an A12 Bionic chip or newer; every iPhone that runs iOS 17 qualifies.
