Balancing Shareability and Positive Interdependence to Support Collaborative Problem-Solving on Interactive Tabletops

Table 1

Four defined collaboration categories indicating different approaches of participants when working together.

	Disc: Active discussion about the task or proposed strategies. Only minor system interaction (e.g., pointing to items or marker use).
	SP: At least one person is actively interacting with the system. The other(s) are actively watching, engaged in conversation about and/or commenting on the observed activities. All group members are working on the same problem. Gestures and body language relate to that problem.
	DP: All group members are either actively interacting with the system or engaged in conversation, but system interactions, gestures, or body language relates to different problems.
	D: Only one person is actively working. The other two are watching passively or are fully disengaged from the task.
