This paper describes a design model for the conceptual design of ships. Existing design models have problems such that their operating mode of batch versions cannot reflect the design procedures in reality. Reliability of the results is low because the performance estimations are based mainly on empirical formulas. To improve the problems of existing design models, a new design model has been developed. The new model consists of an interactive user interface, a database of main engines, a database of particulars of existing ships, and ten modules for performance estimations. To develop such a user-oriented system, the concept of graphical user interface (GUI) is adopted.

디지털방송의 애플리케이션(Xlet)은 시청자와 방송프로그램간의 상호작용에 중요한 역할을 담당한다. 현재 이러한 애플리케이션 UI는 평면이미지로 구성하는 것이 대부분이며 화면상 영역은 2차원으로 제한된다. 본 논문은 이러한 2차원의 평면적인 느낌을 극복하고 3차원이 가진 다양한 이점을 살리기 위한 3차원 UI구현방법을 제시한다. 이를 위해, 본 논문은 가상의 3D System, Virtual Timeline, Animation Model 등을 구성하였다. 3D System이란 UI가 3차원 좌표계를 가지기 위한 환경을 말하며, Timeline과 Animation Model은 제한적인 성능의STB에서 보다 진보된 애니메이션을 UI에 적용하기 위한 기법이다. 이들은 다양한 애플리케이션 제작, 서비스 개발 등에 응용이 가능하다. 디지털방송은 매우 빠른 속도로 발전하고 있으며 새로운 형태의 서비스가 속속 등장하고 있다. 이러한 흐름에 발맞춰 3D UI는 기존의 TV 화면에서 보다 진보된 형태의 사용자 인터페이스의 모습을 보여줄 것이다.

Basic components for multimodal interface, such as speech recognition, speech synthesis, gesture recognition, and multimodal fusion, have their own technological limitations. For example, the accuracy of speech recognition decreases for large vocabulary and in noisy environments. In spite of those technological limitations, there are lots of applications in which speech-oriented multimodal user interfaces are very helpful to users. However, in order to expand application areas for speech-oriented multimodal interfaces, we have to develop the interfaces focused on usability. In this paper, we introduce usability and user-centered design methodology in general. There has been much work for evaluating spoken dialogue systems. We give a summary for PARADISE (PARAdigm for Dialogue System Evaluation) and PROMISE (PROcedure for Multimodal Interactive System Evaluation) that are the generalized evaluation frameworks for voice and multimodal user interfaces. Then, we present usability components for speech-oriented multimodal user interfaces and usability testing guidelines that can be used in a user-centered multimodal interface design process.

The interactive display is providing various interaction modes to users through various ubiquitous computing technologies. These methods were studied for their interactions, but the limits that it is provided to only single user and the device usability were generated. In this paper, we propose a new type of spatial multi interaction interface that provide the various spatial touch interactive to multi users in the ambient display environment. Therefore, we generate the interaction surface so that a user can interact through the IR-LEDs Array Bar installed in the ceiling of the ambient display environment. At this time, a user can experience the various interactions through the spatial touch in an interaction surface. Consequently, this system offers the interactive display and interface method that the users can interact through natural hand movement without the portable devices.

Addressing challenges posed by an aging society, this study explores inclusive design orientations for digital medical interfaces catering to the elderly. The aim is to enhance inclusiveness and optimize interactive experiences within the medical system for senior users. Employing inclusive design concepts, the study analyzes characteristics through literature, focusing on functional purpose, interactive behavior, and emotional expression in digital medical interface design for the elderly. User research methods, including in-depth interviews and field research, generate user personas and behavioral analysis diagrams, organizing and categorizing pain points for elderly patients with chronic diseases. The study proposes principles for improving service touchpoints based on inclusiveness, optimizing pain point types and design processes in age-friendly services. These enhancements aim to help the elderly adapt to and integrate into a digital lifestyle.Incorporating inclusive design principles enhances the inclusiveness of service design, improving the service experience for the elderly. Age-friendly service design with inclusiveness serves as a valuable entry point for research targeting elderly populations and provides practical strategies for age-friendly medical service process design.

Traditional broadcasting environment is merged with various interactive broadcasting services, and the users use these services through Set-Top-Boxes. But they have limited user interfaces, which are not suitable for TV environments by adopting internet formats. Therefore, this paper suggests a User Navigating Interface which helps the audiences to select and watch their favorite channels more effectively. Firstly, this paper analyzes EPG interface - the most basic service in interactive broadcasting. Secondly, it suggests a user interface and service structure suitable in the network-integrated TV environment.

Objective: This paper describes the process and results related to the development of gesture recognition-based natural user interface(NUI) for vehicle maintenance e-Training system. Background: E-Training refers to education training that acquires and improves the necessary capabilities to perform tasks by using information and communication technology(simulation, 3D virtual reality, and augmented reality), device(PC, tablet, smartphone, and HMD), and environment(wired/wireless internet and cloud computing). Method: Palm movement from depth camera is used as a pointing device, where finger movement is extracted by using OpenCV library as a selection protocol. Results: The proposed NUI allows trainees to control objects, such as cars and engines, on a large screen through gesture recognition. In addition, it includes the learning environment to understand the procedure of either assemble or disassemble certain parts. Conclusion: Future works are related to the implementation of gesture recognition technology for a multiple number of trainees. Application: The results of this interface can be applied not only in e-Training system, but also in other systems, such as digital signage, tangible game, controlling 3D contents, etc.

This paper describes interactive dynamic simulation schemes for articulated bodies in virtual environments, where user interaction is allowed through a haptic interface. We incorporated these schemes into our dynamic simulator I-GMS, which was developed in an object-oriented framework for simulating motions of free bodies and complex linkages, such as those needed for robotic systems or human body simulation. User interaction is achieved by performing push and pull operations with the PHANToM haptic device, which runs as an integrated part of I-GMS. We use both forward and inverse dynamics of articulated bodies for the haptic interaction by the push and pull operations, respectively. We demonstrate the user-interaction capability of I-GMS through on-line editing of trajectories for 6-dof (degrees of freedom) articulated bodies.

A graphic vehicle modeling pre-processing program and a visualization post-processing program have been developed for AutoDyn7, which is a special program for vehicle dynamics. The Rapid-App for GUI(Graphic User Interface) builder and the Open Inventor for 3D graphic library have been employed to develop these programs in Silicon Graphics workstation. A Graphic User Interface program integrates vehicle modeling pre-processor, AutoDyn7 analysis processor, and visualization post-processor. In vehicle modeling pre-processor, vehicle hard point data for a suspension model are automatically converted into multibody vehicle system data. An interactive graphics capabilities provides suspension modeling aides to verify user input data interactively. In visualization post-processor, vehicle virtual test simulation results are animated with virtual testing environments.
