Neural nets seem to be doing pretty amazing with video as well.....

Eyebrow semaphore? Hand-to-hand Morse Code?

I’ve been thinking a bit about wearable computing and pervasive encrypted communication. I think personal encryption could become more necessary in an age of deep learning enabled fake video and audio. Wearable computing could take readings from your body and environment as a sort of timestamp and fingerprint. It could also enable an easy way to type messages to others privately.

Atreides battle-language, better yet. The signal is encoded in subtle gestures to generate adversarial examples for the language detector.
