Many museums have recently employed digital technologies in exhibition installations to provide visitors with interactive experiences with the installations, not just audiences. However, most of them have focused on the adoption of new prototypes or technologies, not considering user experiences of those systems carefully. This study developed an evaluation tool for usability of the tangible user interfaces and conducted a usability study on museum installations emphasizing user interaction and experience. The evaluation tool is composed of 5 features of tangible user interfaces such as tangible, interaction, convenience, representation, spatial interaction and social interaction, and 24 items. The museum we investigated is the Gwacheon National Science Museum, where 8 installations, classified 4 categories, were selected for the usability study. We recruited 6 undergraduate students, who were divided into 2 teams, each team having 3 students. Three students in a team manipulated and experience each installation together and reported their evaluation score through the questionnaire and interviews. The results showed that the score of the usability for the category 3, which requires students to move their bodies for the interaction, is the highest one because it features with spatial interaction. Students expressed much interest in the category 4, which utilizes users' other senses, however, the score of the usability is the lowest because the interaction is temporary and repetitive. Most installations are well designed in terms of control constraints, legibility, lower thresholds, participation encouragement, and open to the public, but pooly designed in terms of multiple access points, configurability, accurate movement, ambient media, and full-body interaction.

This study attempted to identify differences in user experience such as spatial presence, social presence, flow, empathy, anxiety, and perceived risk between simulating characters of animation and of actual userimage. The playtesting method was conducted on 60 male smokers using 'Smoking Sims', a simulation game produced by The Center for Health Communication Studies. The results found that the simulation of actual image character is higher in the level of perceived risks for smoking, spatial presence, social presence, flow, and empathy than the simulation of animation character. The study shows that identification with a game character affects user experience and enhances the effectiveness of perceived risks as well. It emphasizes the importance of game design to implement identification in serious game like a smoking cessation simulation.

The Forest Visitor Centers for Little Children who means preschoolers is an educational facility that achieves holistic growth by experiencing forests, and it should not be completed by installing specific facilities in the forest environment, but should be a space where preschoolers can play freely in the forest environment themselves. This study comprehensively evaluated the current status of Seoul Forest Visitor Centers for Little Children and suggested space improvement measures to enhance the effectiveness of forest experience. Through the theoretical review, seven spatial elements that enhance the effect of forest experience and six areas composing outdoor play areas were derived to prepare an analysis table for current status evaluation, and field survey studies were conducted on 24 centers in Seoul. Through expert interviews, the physical status was examined from the perspective of childhood education and the experiences of the users were summarized. As a result of the study, the Seoul Forest Visitor Center for Little Children is classified into six types according to the location characteristics and spatial structure, and has the characteristics of each type. The effectiveness of forest experience can be enhanced by identifying and revealing the environmental strengths of individual centers. In the case of outdoor experience learning zones, the proportion of exercise play areas was very large. By evenly organizing the forest experience space for each area, it will be possible to provide more diverse experiences to preschoolers. However, the status of uniform facility-oriented cannot be viewed as a fragmentary factor that lowers the effect of forest experience. The key to increasing the effect of forest experience by inducing creative activities is the spatial composition that considers the surrounding natural environment. Facilities should be a medium to help preschoolers' interest move into the forest. This study prepared data to understand the average physical status of the Seoul Forest Visitor Center for Little Children and suggested space improvement measures to increase the effectiveness of forest experience. This can be used as basic data for research to improve the quality level of the Seoul Forest Visitor Center for Little Children about 10 years after the project was implemented.

For last decades, the interests and efforts to enhance healthcare facility users' experience is focused on improving facility environments for healing (Delvin, 2003) and servicescapes in order to meet the users' needs (Becker, 2008; Seunghee, 2011). In the emerging experience economy, customer want experiences and they're willing to pay for the experiences and memories not goods. (Pine, J. & Gillmore, J., 1999). It is important to identify what supports customer experiences and how they perceive the experiences in healthcare environments and it will provide important information for healthcare planners, managers, architects, and interior designers. This study examines the service user experience design elements from a User Experiences design perspective. It focuses on healthcare facilities as user experience elements and build up a conceptual framework that outlines service user experience design elements in healthcare facilities. Literature review and case studies were conducted to build the service user experience design elements according to affordance theory. Findings from this study shows that service user experience design elements were introduced and newly developed which can be categorized into three factors; 1) Functional experiences in the physical environments (safety, accessibility, self-directiveness), 2) emotional expression and cognitive experiences (identifiability/clarity, natural features/pleasant environment, aesthetic elements/playful space, media richness), 3) social relational experiences(closeness, privacy, communication with staff, integrated system). These service user experience design elements will help healthcare facility designers to understand what customer experiences, how they increase the satisfaction, and how they improve facilities for modeling the industry's best practices.

This paper analyzed the interregional flow changes of software (SW) industries using a GIS Flow Map. Employment data for SW enterprise headquarters from 1999 until 2008 were constructed according to the Origin-Destination Matrix, and were mapped and analyzed using the Flow Mapper and ArcGIS Flow Data Model. From the result we can identify the decentralization of interregional flow in SW industries and recognize the possibilities of the larger SW enterprises' employment, the higher locational footlooseness. The GIS Flow Map was identified as useful tool for researching growth, decline and spatial movement of industrial clusters that experience business relocation. This method can be applied to understand and visualize urban spatial changes.

This paper presents a method that generates alternatives of spatial arrangement for naval ships with limited information. To attain this end, GA (General Arrangement) methodology and GA reports of existing naval ships are analyzed. In order to improve the current naval ship spatial arrangement method that relies on the experience and know-hows of designers, we propose a systematic spatial arrangement process using SLP (Systematic Layout Planning), which determines relative positions of the components by analyzing relationships among them. The proposed method, along with the GA process, is applied to a virtual naval ship and layout alternatives are generated to verify usefulness of the method.

Light is the essential element for people to live and do creative activities in architecture. The meaning of light has been changed as time has changed, and today it has more sophisticated roles. The meaning of light was to create static ambience in the past but it can create dynamic ambience currently. The digital light can be a source which creates this dynamic effects such as a human behavior, thought and weather data, and also creates new realm of spatial experience such as the metaphysical. complex, and illusionary space. These characteristics can be revealed from Proun raum spatial characteristics. This study analyzes the characteristics of proun raum, and also compare such characteristics to the variable meanings of digital light.

Packet losses tend to occur during short error bursts separated by long periods of relatively error-free transmission. There is also a significant spatial correlation in loss among the receiver nodes in a multicast session. To recover packet transmission errors at the transport layer, tree-based protocols construct a logical tree for error recovery before data transmission is started. The current tree construction scheme does not scale well because it overloads the sender node. We propose a scalable recovery tree construction scheme considering these properties. Unlike the existing tree construction schemes, our scheme distributes some tasks normally handled by the sender node to specific nodes acting as repair node distributors. It also allows receiver nodes to adaptively re-select their repair node when they experience unacceptable error recovery delay. Simulation results show that our scheme constructs the logical tree with reduced message and time overhead. Our analysis also indicates that it provides fast error recovery, since it can reduce the number of additional retransmissions from its upstream repair nodes or sender node.
