Components of the architecture design. The \emph{event driver}
translates device-specific messages to low-level ``events''. These
events are delegated to a number of \emph{event areas} (1), which
restrict events to an area on the screen. \emph{Gesture trackers}
translate low-level events to high-level ``gestures'' (2), which
are handled by the application (3). Dotted arrows represent a flow
of gestures, regular arrows represent events (unless labeled
otherwise).
}
\caption{Extension of the diagram from figure \ref{fig:basicdiagram},
showing the position of the event driver in the architecture. The
event driver translates driver-specific to a common set of events,
which are delegated to analysis components that will interpret them
as more complex gestures.}
