Love this drawing by the way…
Heather Zheng and Ben Zhao, computer science professors at the University of Chicago created a wearable that jams microphones. I immediately thought of Alexa/Echo/Google Home type things, but their demo video reminded me that we may be surrounded by devices that are listening to everything all the time.
This is a just a proof of concept, but with a smaller form factor, I could see people using this. I wonder if it might be more fashionable as a necklace or hat, so long as it doesn’t reduce its ability to jam microphones.
It reminds me a of the infrared privacy glasses that we saw a few years ago. I could see these used together to help insure some privacy in our increasingly surveilled world.
