Meta's ships facial recognition on smart glasses
Key takeaways
- Stella is the companion app for Meta's smart glasses.
- I want to be precise about what that does and does not mean, because the gap between the two is important.
- What I can demonstrate: the machinery is present, it is wired together.
Stella is the companion app for Meta's smart glasses. Inspecting version 273.0.0.21 of the Android build (com.facebook.stella), I found the entire computational and storage stack for on-device facial recognition: three face models, a local database schema, a cosine-similarity vector index dimensioned to match the models, a write path that stages biometric records to disk, a fully wired notification surface, and a user-facing "Connections" widget.
I want to be precise about what that does and does not mean, because the gap between the two is important.
What I can demonstrate: the machinery is present, it is wired together. Several facial extraction and facial fingerprinting models are present and I was able run the recognition pipeline end-to-end on a test image and it detected a face, generate a 2048-dimension biometric embedding, searched a local index, and on a match fired an Android notification stating to the user "Person Recognized".To get the pipeline to run I invoked its existing handler directly with a test photo.
