title = "An exploratory analysis of partner action and camera control in a video-mediated collaborative task",
abstract = "This paper reports on an exploratory experimental study of the relationships between physical movement and desired visual information in the performance of video-mediated collaborative tasks in the real world by geographically distributed groups. Twenty-three pairs of participants (one {"}helper{"} and one {"}worker{"}) linked only by video and audio participated in a Lego construction task in one of three experimental conditions: a fixed scene camera, a helper-controlled pan-tilt-zoom camera, and a dedicated operator-controlled camera. {"}Worker{"} motion was tracked in 3-D space for all three conditions, as were all camera movements. Results suggest performance benefits for the operator-controlled condition, and the relationships between camera position/movement and worker action are explored to generate preliminary theoretical and design implications.",
