</table> <p>The double-tap sensor channel triggers an event whenever a double-tap
is detected on the device. The event data is a bitmask with appropriate bits
set to indicate the direction of the double-tap. The bitmask values are specified
in the <codeph>sensrvtappingsensor.h</codeph> header file.</p></section>
