Abstract.

In this paper we introduce a novel approach to share context to enhance the social quality of
remote mobile communication. We provide an analysis of how people start a conversation in situations
where they meet physically, especially looking on the influence of the situation. Than this is compared to
the way remote communication is initiated using mobile phones. The lack of knowledge about the situation
on the other end leads to initiation of calls that are not appropriate in the situation. The solution we propose
is to exchange context information before initiating the call. We implemented this concept using the
Wireless Application Protocol (WAP). The WML-based Application Context -Call offers a phone interface
that provides information about the receiver when setting up a call. The caller can than decide based on that
information to place the call, to leave a message or to cancel the call. Privacy issues that arise from this
technology are discussed, too.
