To support collaboration, researchers from different fields have proposed the design principles of shareability (engaging users in shared interactions around the same content) and positive interdependence (distributing roles and information to make users dependent on each other). While, on its own, each principle was shown to successfully support collaboration in different contexts, these principles are also partially conflicting, and their combination creates several design challenges. This paper describes how shareability and positive interdependency were jointly implemented in an interactive tabletop-mediated environment called Orbitia, with the aim of inducing collaboration between three adult participants. We present the design details and rationale behind the proposed application. Furthermore, we describe the results of an empirical evaluation focusing on joint problem-solving efficiency, collaboration styles, participation equity, and perceived collaboration effectiveness.

This paper discusses theoretical and methodological issues arising from a video-based research design and the emergent tool ‘Joint Screen’ when grasping joint activity. We share our reflections regarding the combined reading of four synchronised camera perspectives combined in one screen. By these means we reconstruct and analyse multimodal moment-to-moment interaction between young peers engaged in an open-ended baking activity. We rely on a fine-grained analysis of three multimodally transcribed video extracts to highlight how a combined viewing of multiple joint camera perspectives provides access to how participants do joint activity through the simultaneous and continuous use of embodied resources. We argue that ‘Joint Screen’ generates an ‘expanded-around’ view that allows the capture of multimodal interactional processes in their phenomenal depth in time and space.

This paper is concerned with how the spatial distribution of written informings in a serious game activity at an interactive tabletop (ITT) induces participants to read aloud interactionally relevant information to each other in the process of co-constructing a shared understanding.Engaging in an unfamiliar game activity, the participants are all equally dependent on written informings from the interface that serve as a game manual and provide crucial information for jointly achieving the game task(s). When it comes to making use of these written informings, we find the participants to read them aloud, making them accountable within the group.Our findings from multimodal video analysis of two reading-aloud cases suggest that the written informing’s directionality and distribution (here, either designed as ‘distributed’ or ‘shared’ among the interface) regulate the participants’ access to information. And that participants who cannot visually access the information they are interested in reading (aloud) co-organize fine-grained joint successive actions build on and actualized by read-aloud utterances. These joint actions allow them to align their orientation and share their understanding of game activity-relevant content.
