1. A system comprising:
- an array of microelectromechanical systems (MEMS) acoustic sensors each configured to detect an object; and
a gesture recognition component configured to recognize a gesture based on a time sequence in which the MEMS acoustic sensors of the array of MEMS acoustic sensors respectively detect the object.

Abstract
Microelectromechanical systems (MEMS) acoustic sensor-based gesture recognition associated with detecting gestures is described. Provided implementations can comprise MEMS acoustic sensor elements that receive signals reflected off an object. A time sequence associated with each of the MEMS acoustic sensor elements detecting proximity of the object is determined. A gesture is identified based on the time sequence. Functions of a device are controlled according to the gesture.
