Conversation Support for Persistent Mobile Interaction

In this paper we propose a 2*2 matrix as a way of pointing at two new directions for supporting persistent conversations in mobile settings. These two directions include: 1) mobile support for asynchronous and long-term conversations, as well as 2) mobile support for synchronous and short-term conversations. The research presented in this paper builds upon both empirical studies conducted of mobile work forces, as well as theoretical work on CMC (Computer-Mediated Communication) for mobile settings. In this paper we also outline 7 requirements derived from our previous empirical and theoretical work. We then exemplify the two new directions proposed with two novel systems that support asynchronous and long-term conversations (i.e. the RoamWare system) and synchronous and short-term conversations (i.e. the SeamlessTalk prototype). Having exemplified the 2*2 matrix we then discuss how the two systems meet the 7 requirements identified before concluding the paper.
