\section{Introduction}

Following the vision of the ``Internet of Things'', the amount of wireless
devices is steadily increasing, which not only improves our standard of living
in an age where information is expected to be available at one's fingertips, but
also poses challenges. New devices need to be integrated into existing network
setups, but when considering sensor nodes with very limited input capabilities,
manual configuration can be a cumbersome process -- such devices must be readily
usable out of the box, and should interoperate with existing infrastructure.
Moreover, users need to communicate with their devices, they need to know which
devices exist and use the information they collect, while too much or
unstructured information leads to information overflow, effectively discouraging
the user from using the network. 

This paper gives an overview of the ``Chatty Things'' approach as presented by
Klauck and Kirsche~\cite{klauck-kirsche-chattythings}, which proposes solutions
for information filtering, auto-configuration of devices and service discovery,
while using standard chat clients for human-to-machine communication.
Section~\ref{sec:prereq} shortly introduces the used techniques,
Section~\ref{sec:arch} describes the proposed system architecture for Chatty
Things, and Section~\ref{sec:discussion} discusses possible future enhancements
and compares Chatty Things to similar approaches.
