I am using Elisha Hung XCode App Project to basically capture iPhone X facial animation and bring the data into Blender. For more details of this project you can visit my Blender Sushi blog.
- Animation Nodes
- AddOSC (for OSC input)
You will need XCode or an app already installed on your iPhone X that can send the data. I am using my own custom OSC app that is sending Blendshapes coefficient in realtime. In theory, you could do the same using iPhone capability to send mesh data into another iOS or OS device.
