Traces in Virtual Environments: A Framework and Exploration to Conceptualize the Design of Social Virtual...

Creating social Virtual Environments (VEs) is an ongoing challenge. Traces of prior human interactions, or traces of use, are used in Physical Environments (PEs) to create more meaningful relationships with the PE and the people within it. In this paper, we explore how the concept of traces of use can be transferred from PEs to VEs to increase known success factors for social VEs, such as increased social presence. First, we introduce a conceptualization and discussion ($N=4$ expert interviews) of a "Traces in VEs" framework. Second, we evaluate the framework in two lab studies ($N=46$ in total), exploring the effect of traces in (i) VE vs. PE, and (ii) on social presence. Our findings confirm that traces increase the feeling of social presence. However, their meaning may differ depending on the environment. Our framework offers a structured overview of relevant components and relationships that need to be considered when designing meaningful user experiences in VE using traces. Thus, our work is valuable for practitioners and researchers who systematically want to create social VEs.
