“Tap” is a compelling addition to a user interface in for many products. Kionix was an innovator of tap-detection technology, including Directional Tap/Double Tap™, which allows a device to detect the direction of a tap and distinguish between a single tap and a double tap. Tapping is challenging due to the high bandwidth requirement (600-800Hz) of the signal. As the signal is dependent on the position of the sensor related to the tapping, a higher margin is needed. This means a higher threshold and measurement range as well, at 2g or 4g.
