Amplified Collaboration Environment(ACE) is a display-rich project room that enables distributed teams to intensively work together to solve a complex problem. This paper presents reviews of some most important shared workspace models in real-time collaboration systems. It then describes a set of iterative design studies of evaluation the shared workspace for ACEs. The study involved small groups of users in two ACEs performed a collaborative visualization and analysis task while varying the display technology configuration. The goal of this study was to enhance intensive collaborative work in ACEs. The results showed that the participants benefited from the ability to see others' work over the high-resolution shared workspace, which helped enhance group awareness and performance.

Collaboration has become essential in the product design process due to internationalized and specialized business environments. This study presents a real-time collaborative 3D design workspace for distributed designers, focusing on the development and the evaluation of new interaction techniques supporting nonverbal communication such as awareness of participants, shared manipulation and tele-presence. Requirements were identified in terms of shared objects, shared workspaces and awareness through literature reviews and an observational study. An Augmented Reality based collaborative design workspace was developed, in which two main interaction techniques, Turn-table and Virtual Shadow, were incorporated to support shared manipulation and tele-presence. Turn-table provides intuitive shared manipulation of 3D models and physical cues for awareness of remote participants. Virtual shadow supports natural and continuous awareness of location, gestures and pointing of partners. A lab-based evaluation was conducted and the results showed that interaction techniques effectively supported awareness of general pointing and facilitated discussion in 3D model reviews. The workspace and the interaction techniques can facilitate more natural communication and increase the efficiency of collaboration on virtual 3D models between distributed participants (designer-designer, engineer, or modeler) in collaborative design environments.

Most tiled display systems supported a public workspace model where multiple users share the contents and work together on a large public screen. In this research, we developed ICE Display Framework, designed for supporting easy construction of tiled display applications allowing mixed-focus collaboration. Mixed-focus collaboration is a model that allows a number of users to work together as a group or individually on the large workspace. ICE Framework allows users to add personal contents on the tiled display without interrupting other users as well as to put shared works. In this paper, we compare ICE framework with previous research and explain the detail implementation. Then, we introduce the applications built with this framework and discuss the evaluation and analysis of the performance of the new framework.

The purpose of this research is to develop a collaborative architectural design system. Design collaboration requires an extensive use of communication methods as well as the participation of various experts from different domains. Such facts address several issues when the Internet and digital media are able to create a completely new work environment. The building design process was studied, and possible modes of design collaboration were defined. A prototype system is being developed in accordance with the defined collaboration model. The system integrates a set of communication tools and web-based design media. Such media include a synchronous multi-user web CAD tool, a schematic 3D design tool, and a electronic whiteboard. A project database was designed in order to coordinate the project-wide communication which elaborates technologies such as web-based data access. In order to find out the effectiveness of the system, a usability test was performed both in quantitative and qualitative manner. The research will contribute to the development of world-wide design and construction collaboration through the Internet, which is becoming a mainstream building process model.

Based on the current status of use of L-Commerce installed in the Yongsan Public Library and Mapo Lifelong Learning Center, this study suggested the direction of spatial design for the public library's makerspace with L-Commons model. To this end, we investigated the literature research on library makerspaces and the case studies of makerspaces installed in 25 public libraries in Korea and 18 public libraries in the US. And In-depth interviews and user surveys were conducted. The public library makerspace presented through this study should be an open space where everyone in the community can easily enter, break down barriers between all classes in the region, and lead to smooth communication. Second, it should be a learning, cooperation, and creative space where resources can be shared and cooperation for creative activities and projects can be carried out. Third, it should be a creative workspace where community members can turn ideas into physical things that anyone can't do elsewhere or work on something interesting.

Because shipbuilding is single-product production with limited resources, production management technology is essential to manage the resources effectively and maximize the productivity of ship-process. Therefore, many shipbuilding companies are conducting research on ship production plan and process considering various constraints in the field by applying modeling and simulation. However, it is difficult to provide accurate production plan on sudden schedule and process changes, and to understand the interconnectivity between the processes that produce blocks in existing research. In addition, there are many differences between the production planning and field planning because detailed processes and quantity of blocks can not be considered. In this research, we propose the integrated process-based modeling method considering process-operation sequences, BOM(Bill of materials) and resource constraints of all the scheduled blocks in the indoor system. Through the integrated process-based model, it is easy for the user to grasp the assembly relationship, workspace and preliminary relationship of assembly process between the blocks in indoor system. Also, it is possible to obtain the overall production plan that maximizes resource efficiency without the separate simulation and resource modeling procedures because resource balancing that considers the amount of resource quantity shared in the indoor system is carried out.
