Abstract
AbstractIn recent, numerous useful visual analytics tools have been designed to help domain experts solve analytical problems. However, most of the tools do not reflect the nature of solving real-world analytical tasks collaboratively because they have been designed for single users in desktop environments. In this paper, a complete visual analytics system is designed for solving real-world tasks having two integrated components: a single-user desktop system and an extended system suitable for a collaborative environment. Specifically, we designed a collaborative touch-table application (iPCA-CE) by adopting an existing single-user desktop analytical tool (iPCA). With the system, users can actively transit from individual desktop to shared collaborative environments without losing track of their analysis. They can also switch their analytical processes from collaborative to single-user workflows. To understand the usefulness of the system for solving analytical problems, we conducted a user study in both desktop and collaborative environments. From this study, we found that both applications are useful for solving analytical problems individually and collaboratively in different environments.

We found that single desktop environments have advantages for providing private working environments that help users concentrate on solving analytical problem themselves without getting interrupted by other people
Summary
Collaboration in real-world analysis can be regarded as a process of working together or sharing decision-making to develop a joint strategy or answer for the given complex tasks. It has been known that real-world analysts typically perform both individual and group tasks, and as a result must frequently transition between single-user and multi-user collaborative workflows during the course of their analysis [2,3]. Despite this fact, most visual analytics solutions have been designed either as standalone single-user applications or as purely collaborative systems, and very few analytical tools have been developed that cohesively support both activities. A complete visual analytical system is designed for solving real-world tasks ought to have two integrated components: a single-user desktop application and an extended system suitable for a collaborative environment. Despite the costs of converting an existing application into a new interaction modality, we believe that supporting both single-user and collaborative work in an integrated fashion provides important benefits for real-world analysis
