Abstract

We want to enable users of CSCW technologies constant accessibility without inappropriate interaction. Informed by empirical studies, we suggest two mechanisms to realize the objective. The accessibility mechanism filters incoming interaction based on the accessibility plan of users. The awareness mechanism helps people to form an understanding of each others' activities in the process of establishing interaction. To demonstrate how the mechanisms could be implemented, we describe a PC based prototype application called the Interaction Manager. We conclude that the two mechanisms help people extend accessibility and decrease inappropriate interaction.
