FAQ
How does LAPLACE Persona Tracker work?
LAPLACE Persona Tracker uses ARKit to track over 50 facial expression shapes, head rotation, and position up to 60 times per second. This tracking data is then streamed over your local Wi-Fi network to compatible desktop VTubing software like LAPLACE Persona.
What devices are compatible with LAPLACE Persona Tracker?
The app is compatible with iPhone and iPad devices running iOS 17 or later. Face tracking specifically requires a device with Face ID or an A12 Bionic chip or newer, which includes all iPhones that run iOS 17.
Does LAPLACE Persona Tracker require an internet connection?
No, LAPLACE Persona Tracker does not require an internet connection or cloud services. Tracking streams directly over your local Wi-Fi network between your mobile device and your computer.
How does LAPLACE Persona Tracker handle privacy?
Privacy is a core focus. Camera video never leaves your device, and only tracking values are sent to your chosen computer. The preview displays a wireframe mesh of your face, not the camera feed, and an option for Normalized Face Mesh replaces your face with a generic one on screen.
