This research suggests scenarios of learning in real life contexts with smart devices and provides user interface prototypes to show their characteristics more effectively. For this, literature review was conducted to understand the strength and limitations of current learning in which real life contexts are used. Then, the characteristics of smart devices as a support tool of learning service was reviewed. With such understand, a user research was executed to establish 10 design guidelines for learning service in real life contexts. Finally, this paper suggested two scenarios that shows learning in real life contexts as case studies and their detailed user interface protypes.

Recently DSP chips are widely used in high quality car audio to achieve high quality sound and to process various sound sources, e.g. navigation, cell phones. In this paper, we developed a set of design tools useful for developing high quality car audio systems using Philips' SAF7730 car audio chips. The tool is consist of the GUI(Graphic User Interface) program running on the Windows operating system and the interface board which performs data conversion between RS232C and I2C protocols. The developed system has been successfully applied to commecial car audio design.

We described an integrated management system, which is a design system of suction muffler(SMDS). SMDS constructs a virtual design system and possesses a Mutual Interfacing Module function using a Remote Analysis function and a GUI(Graphic User Interface). This system consists of a sever and clients. Client performs modeling and preprocessing, and server analyzes the results. The system uses Telnet and FTP based on TCP/IP protocol for connecting a client with a server.. It uses a PC at each work place as a basic platform for design and analysis of goods, and si able to manage a project as a unit. It is shown through an exsample that it is useful as a design tool in the fields.

In this paper a free-form hull design program and performance prediction program for planing boat is introduced. This program enables the designer to do complex geometric hull shape design on a personal computer and accurately to predict power requirements for a given loading and velocity. For a free form design, Bezier curve model is adopted as a basic representation tool of curves and surfaces, and this program has versatile functions to do fairing jobs with a convenient graphical user interface. After creating a hull form the geometric data is provided in a manner compatible with a variety of analysis tools including 'Motion Analysis(by Zarnick)' for prediction of motion characteristics in regular waves, 'Running Attitude (by Savitsky)' for prediction of the running attitude and required power.

We developed a Off-Line Graphic Simulator which can simulate a robot model in 3D graphics space in Windows 95 version. 4 axes SCARA robot was adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed program. The interface between users and the off-line program system in the Windows 95's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D graphics.

In this paper, a software development for design of the small photovoltaic system which is used to LED lighting is presented. For optimal design of photovoltaic systems, the operating power consumption of the LED load is considered to estimate the capacity of the solar module and battery. In order to give system design engineers a high ease of use, the software tool provides a graphical user interface and monitoring function to check operation of the system prior to installation.

This paper describes the development of automatic shape design program for spur gear. It produces automatically third-dimensional surface and solid model used in CAD/CAM system with inputting simple measurements. This program can maximize user's convenience and get surface and solid model quickly as accepting GUI(graphic user interface). Automatic shape design program for spur gear was developed by Visual LISP, a developer program. Besides, a geometrical method and a mathematical algerian are used in this program. Use frequency of a fine spur gear is on the increase recently and manufacture process of this gear is heat treatment after press processing with molding. In this press processing, the upper punch portion of a fine spur gear shape is drafted by CAM. Therefore, estimated that surface and solid model of spur gear used to CAM are needed in this research. In this research, after 2 ㎜ gear was modeled by auto shape design program, the upper punch portion of a fine spur gear was manufactured as giving third-dimensional model to CAM software and then, displayed the result as applying to press process.

The purpose of the study is to design and implement a prototype expert system for library classification in the literature field of the DDC 20. The system was largely consisted of a knowledge base, an inference engine, a knowledge acquisition facility, an explanation facility and an user interface facility. The knowledge base was represented by inference rules and frames. The name file for authors and titles was designed separately. The forward chaining technique was chosen for the inference engine and the menu-driven dialog technique was also taken for the user interface. The conclusions of the study can be summarized as follows: 1) The difficulty of document classification work is due to the complex and stringent classification rules. Such problems can be considerably alleviated by using the present system. 2) Even the novice with a knowledge about the DDC 20 can easily access the system. And also librarian other than the professional classifier can easily be accustomed to the classification work. 3) The system can be used as an online classification scheme. 4) By adding any local language other than English or Hangeul on the menu screen, the language problem relating classification can be overcome. 5) The system can be employed as the intensification tool for the education of classification as well as library automation.
