A group of researchers from the University of California, Irvine, have developed a way to use the sensors in high-quality optical mice to capture subtle vibrations and convert them into audible data. According to the abstract of Mic-E-Mouse, the high polling rate and sensitivity of high-performance optical mice pick up acoustic vibrations from the surface where they sit. By running the raw data through signal processing and machine learning techniques, the team could hear what the user was saying…
