The fact that if I hadn't used a physical barrier then my face would have been immediately fed into a detection algorithm without any explanation or warning.
I get that it's just a tech demo but a small disclaimer about what will be done with the data before requesting the permission would go a long way.
Yeah it doesn't need to be long (short is actually better as more chance of people reading it through)
1. The app requests permission to view your camera
2. Your video stream is displayed and a local js script will run facial recognition (not against a database, just a binary "is this a face") and only then will it allow you to join the chat.
3. When you join the chat, your video and audio will be transmitted but will not be stored.
some people likely won't even read it and just click anyway, but for the curious and/or paranoid it will definitely be reassuring.
Maybe, but it makes it impossible for me to test it at the moment as my webcam doesn't capture enough light to get the face detection working apparently.
