And before you ask, no, these glasses aren't part of elaborate spider-person cosplay get-up. To their credit, Echizen says the glasses successfully screwed with smartphone cameras' facial recognition systems 90 percent of the time. Earlier prototypes sought to obscure our visages with infrared LEDs (like this hacky pair we played with at Mobile World Congress), which were arguably a little more technically impressive -- the LEDs looked inert in normal light but lit up in front of cameras, casting a weird halo around a person's face. This sort of obscurantist tech is just a little less awkward to wear in public, and Echizen says this new pair shouldn't screw with your vision too much (though driving or riding a bike could be tricky). Of course, no pair of funky glasses will keep your friends from tagging you in photos on Facebook but they should help keep those pesky algorithms at bay. Alas, you can't hide your face in plain(it) sight until June 2016, when Echizen hopes to get them onto the market for about $240.
