Not many years ago, people found the contemporary technology expensive and difficult to use in collaborative type of meetings. Today, with the technology advanced to high standards and accessible at cheaper price, its adaption is becoming more and more ubiquitous with wide range of applications. Today's meeting rooms are not just plain old telephone systems with microphones and speakers. Today's meeting rooms are smart and intelligent. They can identify the participants; they can provide natural view of remote participants; they can proactively manage resources for collaboration and so on. More effective collaboration is possible with deployment of devices like high-definition cameras, advanced displays, sensors, gigabit networks, trackers, pointers, and high-end audio devices. Devices alone are not enough in the meeting rooms. We need software infrastructure to manage the devices and meeting contexts. One such software infrastructure is SMeet, a Smart Meeting space, which we have developed to provide an effective multi-party remote collaboration environment. Networked display systems are used in such advanced collaboration environment for better visualization. In this paper we discuss a novel approach to control and manage networked display systems in SMeet environment.

Many of hotel customers obtain information from hotel websites to find the best alternative. One of the crucial information for the choice is spatial/visual information of hotel rooms. However, hotel website provides photographs only showing representative room features that may not be sufficient to give a full understanding of hotel room to customers. HMD-based 3D virtual environments (HVE) created by 3D camera could improve customers' experiences of hotel rooms by providing full virtual tours of hotel rooms. However, to the best of our knowledge, whether HVE can adequately provide similar customers' perception on spatial/visual information remains unproven as physical hotel rooms. The present study thus aims to verify how similar and reliable information on physical hotel room HVE provides to hotel customers in comparison with hotel website with 2D photograph and display-based 3D virtual environment. For this purpose, this study conducted a comparative experiment to investigate perception of three environments. As a result, the study found that HVE is more effective to provide spatial/visual information as similar as an actual hotel room. In addition, HVE increases customers' perceptions towards the reliability of information, the quality of hotel room and intention to book.

Objective: This study proposes an alarm display and compares it with the one(alarm tile display) widely used in main control rooms(MCRs) of nuclear power plants. Background: Catching up with the rapid development of computer technologies, advanced MCRs has been required. Using modern technologies of computers and visual displays, we have a lot of potential to improve user performance and satisfaction as well as safety in MCRs. Method: The alarm bar display has been proposed to reduce some potential problems of the alarm tile display in this study. Human factors evaluations were conducted to compare both types of displays. Two interfaces of bar alarm and tile alarm were simulated on the desktop computer for the user-involved experiment. Eight students participated in the experiment with the within-subject design. Results: The alarm bar was slightly better in terms of situation awareness, and preferred to understand alarm dynamics. The alarm tile was slightly or significantly better in other measures. Conclusion: Both alarm displays have their own advantages and disadvantages. Therefore, combining benefits of both displays can be used to optimize the design of alarm displays. Application: The proposed display is expected to compensate the existing displays for certain purposes.

In order to produce a variety of lighting effects most of the modem museums use various light sources in the same space. This indicates, in other words, that each item on display is being exposed to a different lighting environment. There are required, however, different conditions for optimum environments for displaying and preserving items, respectively. In this research visible rays, ultraviolet rays and infrared rays measured in the show cases and display rooms of the National Museum of Korea were analyzed to assess its lighting environment.

Objective: Two control rooms of a petroleum complex were ergonomically evaluated for this study using diverse drawings of the rooms. The objective of the study is to show the evaluation process and its results, assessment method and essential elements for drawing-based ergonomic evaluation. Background: Ergonomics can enhance the working environment and safety for a control room when implemented effectively. A control room design was examined by ergonomists based on ergonomic principles and well-practiced standards. This study was conducted because a construction consortium wanted to perform an ergonomic evaluation of the control rooms before the construction. Method: A simple evaluation process, composed with a pre-evaluation, an evaluation and a post-evaluation, was employed to carry out the study. ISO 11064, NUREG-0700, NUREG/CR-6150, and CRIOP were reviewed to evaluate the control rooms. The assessment ranges over the control room layout, workstations, display and control, environmental requirements and safety. Three ergonomists participated in the study and performed the evaluation for two months. Results: An experienced consortium of construction companies designed the petroleum complex and control rooms. No significant ergonomic design problems were detected. Quantitative recommendations were provided for the layout and workstation dimensions. Specific design directions were also proposed for environmental requirements and safety. Conclusion and Application: Design advice and minor potential problems were reported as results of the drawing-based ergonomic evaluation. More practical suggestions could be additionally provided if an on-site assessment was conducted. However, the ergonomic evaluation used in this study could be helpful and applied to designing and evaluating other various control rooms prior to their construction.

There is mounting evidence that complex computer system displays in control rooms contribute to cognitive complexity and, thus, to the probability of human error. Research shows that reaction time increases and response accuracy decreases as the number of elements in the display screen increase. However, in terms of supporting the control room operator, approaches focusing on addressing display complexity solely in terms of information density and its location and patterning, will fall short of delivering a properly designed interface. This paper argues that information complexity and semantic complexity are mandatory components when considering display complexity and that the addition of these concepts assists in understanding and resolving differences between designers and the preferences and performance of operators. This paper concludes that a number of simplified methods, when combined, can be used to estimate the impact that a particular display may have on the operator's ability to perform a function accurately and effectively. We present a mixed qualitative and quantitative approach and a method for complexity estimation.

Today's driver information system often features a rotary control type as a main controller for menu navigation. Population stereotype should be clearly understood in designing those systems to minimize the misunderstanding by the operator. This paper investigates stereotypes for rotary controlled menu interfaces and influences of contributing principles. A human factors experiment was conducted using various configurations of control-display layouts, cursor shapes/positions, and movement directions. The results showed that the control should be on the left of the display, with a rightward icon on the right side of the cursor, in order to match the stereotype. Regression analysis indicated that Warrick's principle was the most influential principle, followed by Icon shape, Icon position, Clockwise away, and Clockwise up principles. This study provides valuable information to designers of menu-based systems such as driver information systems and main control rooms that uses rotary controls.
