These smart glasses promise to turn your silent mouth movements into text
Crazy person, or efficient employee? As always, it depends on what they're wearing
Smart glasses developed by Subvocal, a Y Combinator-backed startup, aim to convert silent mouth movements into text. The device, which has working prototypes, uses low-powered radio waves projected towards the wearer's face to detect muscle movements and changes in facial shape that occur while speaking or mouthing words. These signals are then translated into written text.
Although the final product will look sleeker, the current headset is more of a prototype, as seen in YouTube videos featuring YC partner Dave Lieb. Pre-orders for the glasses are available now for $199, with the remaining $300 due upon delivery. The founders, Aarush Yadav and Arnav Kumar, are Georgia Tech computer science students who developed the technology after competing in a hackathon.
They initially used EMG electrodes but later switched to RF sensing, which proved to be a significant engineering challenge. The company aims to make silent speech an efficient interface for interacting with computers, allowing users to send emails, prompts, messages, code, notes, and commands at the speed of speech without disturbing others.
