Viewpoint about the quality of software is various. But, from the end-user point of view, user interface of software may be all to express the quality of software. But the detailed evaluation criteria were not established about usability evaluation method based on user interface so far, though user interface of software is the main object of usability quality characteristics. In this paper, we established a system about the method extracting and evaluating some quality characteristics elements measurable form user interface of software by analyzing the relationship between the elements constructing quality characteristics and user interface related to quality evaluation of software. We expect that this result of study will be a fundamental study adapting and evaluating to various types of user interface.

This paper describes an study electric injection system for diesel engines. It is needed effective fuel injection which controls the solenoid valve of fuel pump. To solve this, this paper proposes DCC-PWM method which can realize fast reply and low holding current for solenoid valve on/off. For the proposed design method, simulation tools of ACSL are used to analyze the system. And the single-chip microcomputer is used to reduce the size of controller and to improve flexibility. And the systems validity can be verified through the experimental results.

This paper, discusses about the implementation of the remote control LED Lights in elevator facility Since 1990, the elevator dissemination has greatly increasing. Currently in the elevator most of people they can use smart devices anytime or anywhere to view and retrieve the information by using internet. Therefore, in this paper, efficient management of power LED and LED remote control LED lighting fluid, in order to control features and smart devices can be applied to Web services platform and OS-specific proposals. Additionally based on the configured UI technology and programs offered by the present, and the LED lights are offered through the simulation to efficiently manage technology to demonstrate the usefulness.

Autobike is insufficient of car navigation informations and high of accident dangerousness comparing to car. So if a system providing autobike driver's driving information and e-call function is developed using smart helmet consisting of collision perception sensor, rear camera, bluetooth communication module, MCU and HUD, It is very useful and can decrease of person's damage and handle expeditious traffic accident during autobike accident. In this paper, when this, "Providing system of autobike driver's information and e-call function", software is developed, a proper analysis and design method for practical affairs try to be presented due to showing software development analysis method, architecture of hardware block-diagram, flowchart and UI design.

This theory focuses on the Enterprise Portal and researches and analyzes the user requirement on as-is system. The UI Checklist Matrix is made based on the result of user analysis and evaluation of checklist. The horizontal axis of the Matrix is composed of 6 results(Layout, Navigation, Information, Function, Visibility and Interaction) of user requirement analysis. The vertical axis of the Matrix is composed of 10 subjects, Learnability, Efficiency, Accuracy, Accessibility, Consistency, Agility, Convergence, Personalization, Technology, and Standardization. At the point of vertical and horizontal items meet, indicates the graded of importance and defines a details item. The Guideline in which Matrix is reflected is set and according to the guideline, designing the business screen and assessing the Matrix.

Mobile directory has offered just the same function until now, SNS service also has offered for our to meet other people and liaise between person and person. But it has a important thing which can not offer direct to liaise between person and person. In this paper, we has developed the "SNS Consolidation Directory" for solve the problem which needs to modern people with. A main purpose of SNS Consolidation Directory will develop the smart directory which offer to improve SNS service and personal relation supervision. This system function has initial search, anniversary, birthday alarm, using the UI contact frequency, SNS service and directory exchange.

Rich Internet Application(RIA) is one of the Web 2.0 technologies and is expected to be a next generation user interface technique which allows flexible and dynamic manipulation for Web searches. This paper addresses a personalization mechanism for advanced Web search using RIA for abundant user interactions. We devised a dynamic and graphical user interface instead of previous text-based searches and a client side application for storing personal preference information. In this research, we implemented the graphical personalized search manager using Yahoo web search API and widget, and demonstrated its effectiveness by performing some experiments with various query terms and representative predicates.

In this paper, in order to improve the execution performance and serviceability of cross-platform applications frameworks based on the existing web applications, we design and implement a new hybrid application framework named as WApplE.js, which enables direct control of native UI(User Interface) of mobile operating systems and various resources via JavaScript. We first present the design results for the overall software structure and the configuration of every layer of WApplE.js, and then analyze the processes for calling and handling APIs in the implemented hybrid application framework. In addition, the results of comparison of features to the existing frameworks are presented.

A study on how a launcher as smart phone application was utilized as brand communication by deriving a characteristic element that could be changed into an extended function which carried out brand communication function going beyond the basic function of launcher pre-installed for the purpose of UI differentiation according to each device brand. In the results of analyzing the items and features of brand communication shown in each detailed item after classifying properties of launcher components into that of home component and personalization function element, (1) brand image identity element and (2) service marketing commitment element was derived.

In this study, we found that the design can be configured according to the visual weight in the design of the interface. First of all, interface design has gone through the era of squeeze morphism to express depth and dimension by borrowing part of material design or head design from flat design. This is due to the characteristics of metro UI and flat design, which are difficult to express depth and dimension, but in material design, there was no separate device for inducing eyes, so Gestalt theory showed the principle of visual weight. Positive and negative, the size and placement of regions, proximity, closure, and notion were closely related to visual weight and orientation, and in some cases, it could be applied to the interface.
