Systems and methods are described that use a data stream from an integrated inertial measurement unit (IMU) to identify the location of taps on the body of a handheld device in real time. Taps are generated by tapping the handheld device with an object (e.g., a finger) or by moving the handheld device and tapping it against another object. Measurements of the IMU accelerometer, gyroscope, and / or orientation (relative to the Earth's magnetic field and / or gravity) are examined to find a signature that distinguishes taps at one location on the device body compared to signal characteristics generated by taps at other locations. Neural networks and / or numerical methods can be used to perform such classification. Tap location, tap timing, and tap attributes, such as the magnitude of the applied force, the device's orientation, and the amplitude and direction of movement during and after the tap, can be used to control or adjust responses within the handheld device and / or actions in connected devices.
