Researchers at Cornell University Developed sonar glasses To “listen” to you without speaking. The glasses attachment uses a tiny microphone and speakers to let you pause or skip music tracks, enter passcodes without touching your phone, and work on CAD models without a keyboard. Reads the words you speak when you quietly give commands to
Cornell PhD student Ruidong Zhang developed this system. This system builds on similar projects the team created using wireless earbuds and an earlier model that relied on cameras. The glasses form factor eliminates the need to face the camera or put anything in your ears. His Cheng Zhang, Assistant Professor of Information Science at Cornell University, said: “We’re running sonar on our bodies.”
According to the researchers, the system only needs a few minutes of training data (reading a series of numbers, for example) to learn a user’s speech patterns. Then, when it’s ready for action, it sends and receives sound waves across the face, sensing mouth movements while using deep learning his algorithms to echo her profile in real-time with “about 95 percent accuracy.” Analyze.
The system does this while offloading data processing (wirelessly) to the smartphone, allowing the accessory to be small and discreet. The current version offers approximately 10 hours of battery life for acoustic sensing. Plus, your data never leaves your phone, eliminating privacy concerns. Cheng Zhang said: “It’s small, low-power, and privacy-friendly, all of which are important features for bringing new wearable technology into the real world.”
Privacy is also important given the potential for real-world use. For example, Ruidong Zhang suggests using it to control music playback controls (hands-free and eyes-free) in a quiet library, or to dictate messages at a loud concert. Perhaps the most exciting possibility is that people with some kind of speech impediment will use it to quietly feed dialogue into a speech synthesizer and speak the words out loud.
If you follow the plan, you can get it someday. A team at Cornell University’s Smart Computer Interfaces for Future Interactions (SciFi) Lab is looking to commercialize the technology using a Cornell University-funded program. We are also looking at smart glasses applications that track facial, eye, and upper body movements. Cheng Zhang said:
