This amazing demo shows the ability of the face tracking of iPhoneX and the creator was doing the data transmission wirelessly by storing the data in the phone and later using AirDrop to his Mac.
I wonder if ARKit Remote supports the wireless connection or any awesome developer has created the plugin?
I don’t think ARKit remote will be fast enough. I’ve made a Unity based app that records face blendshapes with audio, and video ref and even face meshes per frame, and using AirDrop it sends these to a computer. Also made an editor script to convert the recorded blendshape data into Unity animations. I haven’t streamed the data in real time yet but that should be totally possible. It’s just a bunch of numbers.
