@nytimes on our Wearable Microphone Jammer (see it in action here: ). it uses ultrasound to disable surrounding microphones from recording you; lead by Heather Zheng & @ravenben with Yuxin Chen, Huiying Li, @tengshanyuan, Steven Nagels and I ->#chi2020 1/N 
@nytimes @ravenben @tengshanyuan Here's how it works: sandlab.cs.uchicago.edu/jammer/ The engineering behind it allows us to get an awesome jamming coverage by making it #wearable : (1) any small movement decreases the impact of the typical blind spots that ultrasonic jammers have; and, (2) it jams in many directions!
@nytimes @ravenben @tengshanyuan What happens when you activate the jammer and talk to someone while surrounded by microphones? Those microphones capture noise rather than your voice, but you don't hear any jamming (it's ultrasonic). This means you speak freely but speech recognizers will fail to spy on you.
@nytimes @ravenben @tengshanyuan If you want to read all the details, I invite you to read our upcoming #chi2020 paper (accessible at sandlab.cs.uchicago.edu/jammer/ or my lab too: lab.plopes.org). This would not have been possible without the great feedback from anonymous @sig_chi @sigchi reviewers! Thanks!
@nytimes @ravenben @tengshanyuan @sig_chi @sigchi Want to build your own? Want to simulate different configurations of ultrasonic jammers? Yuxin Chen put together an amazing suite to simulate this: github.com/y-x-c/wearable… #openscience #chi2020 Before @tengshanyuan , Steven and I built the device we relied on these simulations!
here's us at the lab: me, @HuiyingLi9 , Yuxin Chen, @tengshanyuan and not pictured are the amazing @heatherzheng & @ravenben (the leads of this project) as well as Steven Nagels (who was my visiting PhD student last year at @UChicagoCS ) see you at #chi2020 for our demo!
