High-performance mice can be used as a microphone to spy on users thanks to AI — Mic-E-Mouse technique harnesses mouse sensors, converts acoustic vibrations into speech

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 through their desk. From there, the collected raw data can be extracted from the target computer and processed off-site. The processing works like this: the raw audio data is run through digital signal processing using a Wiener Filter, where you can start to hear some information. The concept of the Mic-E-Mouse is similar — using an unsuspecting device to capture audio data.
