Common ground to analyse privacy negotiation in awareness systems

This paper discusses how Clark’s theory of Common Ground can be applied to analyse how individuals connected by Awareness Systems conjointly meet and coordinate their privacy needs. Relevant aspects of Common Ground theory for the analysis of human communication behaviours are used in this study to understand privacy as a collaborative coordination process. The exposition illustrates how Awareness Systems are a mechanism for helping individuals to meet their privacy needs rather than as a privacy threat, as a first impression might sugges

Behaviours and preferences when coordinating mediated interruptions: social and system influence

There is a growing interest in technologies for supporting individuals to manage their accessibility for interruptions. The applicability of these technologies is likely to be influenced by social relationships between people. This paper describes an experiment that examines interplay between a working relationship of an interruptor and an interruptee and two different system approaches to handle interruptions. We tested how system behaviour and the social relationship between the actors influence their interruption behaviours. Our results are consistent with prior research on the importance of relational benefit to understanding interruption. We found that interruptors were far more likely to be considerate of interruptees' activities, when they both shared a common goal. We have extended those findings by showing that interruptees display similar behaviours to those presented by interruptors. The results regarding the systems’ influence show a clear trend towards the positive effect of the Automatic system on peoples’ interruption behaviours which is based on: (i) visible interruption costs, (ii) social tension and (iii) system preference. We think that the results of this experiment translated into design implications can prove helpful in informing the design of computer–mediated solutions supporting interruption handling

<title>The unbearable lightness of being there: contrasting approaches to presence engineering</title>

The emergence and proliferation of email, mobile communication devices, internet chatrooms, shared virtual environments, advanced tele-conferencing platforms and other telecommunication systems underline the importance of developing measurement methods that are sensitive to the human experience with these systems. In this paper, we discuss the concepts of social presence and connectedness as complementary notions, each relating to a different set of media properties that serve distinct communication needs. We aim to broaden the scope of current presence technologies and applications, illustrating the various factors that play a role in establishing, enhancing, and enriching the experience of human connectedness through communication media. Based on existing literature, we discuss a number of user requirements for home communication and awareness systems. To make these ideas tangible, we finish the paper by briefly discussing the ASTRA project as a case study in designing and evaluating an awareness system for the home
