Digilog Book, the next generation publication material, supplies digitalized contents on an analog book by integrating digital contents into existing analog books. There are some studies related to authoring tools which are to authorize, and publish some books which provide digital contents by using VR or AR techniques. In this paper, a pen-type haptic user interface for Digilog Book authoring tool has been introduced. This haptic user interface is developed for more realistic and more effective authoring tasks. This haptic interface provides haptic effects for authoring tasks which are including translation, rotation, scaling, and menu selection. In this research, we designed a body, control circuits, vibration haptic patterns for haptic user interface, and a protocol for between haptic user interface and Digilog Book main control system. Also a simple user study has been done with a developed haptic user interface.

The design and implementation of the interaction for tangible user interfaces require in-depth knowledge in many different disciplines, such as device control, sensing and calibrating devices, interaction design, low-level programming, and performance tuning. Many trial and error iterations are needed to determine the proper combination of the interaction techniques while using available interaction devices and considering the characteristics of contents. As a result, it takes too much effort and time to achieve maximum usability. This paper introduces a tangible user-interface platform, which is fabricated using various hardware devices and an XML-based authoring tool, which is developed in order to relieve content creators of the burden of the above difficulties. Finally, we demonstrate our work by illustrating some example contents.

In the large and multifunctional engineering system, the heterogeneous computer system situation is inevitable. Accordingly a lot of integration efforts are being made to comply with the industrial requirement of productivity. In this paper, a practical concept of integration is introduced through the development of a prototype system for ship outfitting design which is a typical example of large/multi-functional application system. On the development of the prototype system, three points are considered as a practical concept-which are integration of database, integration of application programs, and system-user interface. The relation model based commercial database management system(RDBMS) is used to build the project integrated database, and the graphical user interface tool(OSF/Motif) on X-window system is used for the integration of application programs and the user interface.

This study aims to validate a web-based neuropsychological testing tool developed by Kwak(2007) and to suggest solutions to potential problems that can deteriorate its validity. When it targets a wider range of subjects, a web-based neuropsychological testing tool is challenged by high drop-out rates, lack of motivation, lack of interactivity with the experimenter, fear of computer, etc. As a possible solution to these threats, this study aims to redesign the user interface of a web-based attention testing tool through three phases of study. In Study 1, an extensive analysis of Kwak's(2007) attention testing tool was conducted to identify potential usability problems. The Heuristic Walkthrough(HW) method was used by three usability experts to review various design features. As a result, many problems were found throughout the tool. The findings concluded that the design of instructions, user information survey forms, task screen, results screen, etc. did not conform to the needs of users and their tasks. In Study 2, 11 guidelines for the design of web-based attention testing tools were established based on the findings from Study 1. The guidelines were used to optimize the design and organization of the tool so that it fits to the user and task needs. The resulting new design alternative was then implemented as a working prototype using the JAVA programming language. In Study 3, a comparative study was conducted to demonstrate the excellence of the new design of attention testing tool(named graphic style tool) over the existing design(named text style tool). A total of 60 subjects participated in user testing sessions where their error frequency, error patterns, and subjective satisfaction were measured through performance observation and questionnaires. Through the task performance measurement, a number of user errors in various types were observed in the existing text style tool. The questionnaire results were also in support of the new graphic style tool, users rated the new graphic style tool higher than the existing text style tool in terms of overall satisfaction, screen design, terms and system information, ease of learning, and system performance.

Recently the studies on user-centered design and form-development have become issues of general interest as the key methods for successful design. For form analysis on user it is important needs that an integrated approach of existing methods and development of expert tool for designer. Moreover analysis methods and tools have to meet with the designers needs of visual result, clear direction, concrete formative factor, user's emotional response and designer-friendly interface. This study proposed the main concepts of form analysis tool based on the user's emotional response ; integrated management, variables set-up, visual result of analysis, in-depth analysis with data mining and correlation, and reinforcement of user-centered analysis. Specific analysis tool consists of 5 functions: Project Management, Analysis Frame Set-up, Data Input-output, Basic Analysis, and In-depth Analysis. The feasibility of proposed tool was verified by a case study of mobile phone design in under-graduate class.

Objective: This study aims to implement a non-contact gesture-based interface for presentation purposes and to analyze the effect of the proposed interface as information transfer assisted device. Background: Recently, research on control device using gesture recognition or speech recognition is being conducted with rapid technological growth in UI/UX area and appearance of smart service products which requires a new human-machine interface. However, few quantitative researches on practical effects of the new interface type have been done relatively, while activities on system implementation are very popular. Method: The system presented in this study is implemented with KINECT$^{(R)}$ sensor offered by Microsoft Corporation. To investigate whether the proposed system is effective as a presentation support tool or not, we conduct experiments by giving several lectures to 40 participants in both a traditional lecture room(keyboard-based presentation control) and a non-contact gesture-based lecture room(KINECT-based presentation control), evaluating their interests and immersion based on contents of the lecture and lecturing methods, and analyzing their understanding about contents of the lecture. Result: We check that whether the gesture-based presentation system can play effective role as presentation supporting tools or not depending on the level of difficulty of contents using ANOVA. Conclusion: We check that a non-contact gesture-based interface is a meaningful tool as a sportive device when delivering easy and simple information. However, the effect can vary with the contents and the level of difficulty of information provided. Application: The results presented in this paper might help to design a new human-machine(computer) interface for communication support tools.

Rapid prototyping technology has been widely applied to the design process in the industry. This technology made it easy to generate a prototype which acts like a real product in logic. However, this technology has not been validated sufficiently as a usability test method. The purpose of this study was to test the hypothesis : There was no significant difference between a real product and its prototype. An experiment was designed to test it statistically. a microwave oven was selected and its prototype was generated using a rapid prototyping tool. Six subjects used the microwave oven and another six subjects used the prototype to perform five scenario tasks. As a result, there was significant difference between the real product and prototype in success rate, task completion time, and number of buttons pressed. The prototype was more difficult to operate than the real product. Therefore we should be careful when we apply rapid prototyping. technology. In the discussions, the causes of the difference were identified and some guidelines were suggested for who wants to apply rapid prototyping tool to the usability test.
