Original Abstract Submitted
Aspects of the disclosure relate to microelectromechanical systems (MEMS) and associated detection and classification of surface impacts using MEMS systems and signals. One aspect is a device including a memory configured to store an audio signal and a motion signal and one or more processors. The processors are configured to obtain the audio signal, wherein the audio signal is generated based on detection of sound by a microphone, obtain the motion signal, wherein the motion signal is generated based on detection of motion by a motion sensor mounted on a surface of an object, perform a similarity measure based on the audio signal and the motion signal, and determine a context of a contact type of the surface of the object based on the similarity measure.
