Usability has become an important consideration for product development, and as a result, there is a growing need for systems and tools that can support usability test projects. However, few studies so far have developed such systems and tools. During a usability test project, many participants take up different roles, such as project managers, usability testers, and subjects. We implement a web-based usability test system with which a project manager can manage and control all participants and documents throughout the entire usability test process, from the design of a usability test project to the analysis of the test results. A usability test generates many documents, such as subject agreement forms and before/after questionnaires. Since many different subjects can participate in a usability test, consistency during testing with different participants and efficient document management are the keys to success for a usability test. Since all users that participate in usability test projects can access web-based usability test systems through a web browser, regardless of the place where they are, the reliability of the testing results can improve since the tests are conducted in the locations where the target products are meant to be used. In particular, our system is useful for disabled individuals who cannot move.

The Internet has been growing explosively in recent years. The Quality as well as the quantity of web material become the interest of both industry and academic field. The purpose of this article is to investigate the possibility of the utilization of the usability test for the improvement of the quality of instructional web contents. Literatures on the usability and usability test was reviewed, a WBI development model was modified to incorporate the usability test, and a website was developed as a case. In developing the web contents, the process of the usability test indicated by the model was applied. Some practical suggestions on implementing usability test were made and the methods of effective use of the test were discussed.

Web-based Assessment System is needed for Process-Oriented Evaluation to integrate instructions into evaluation frequently in Informatics Education, and considered usability for supporting teachers to test more conveniently. First of all, we analyzed usability of traditional Web-based Assessment System, and proposed PBA(Paper-Based Assessment) model by extracting usability features of paper-pencil assessment in off-line. The evaluation system based on the PBA model controls the whole processes of tests; before-test, under-test, after-test. Especially, the system readily can change the target class, and control access to the test page during each step. Thus we can get high credibility about the test results. Moreover, students can login to the paper easily by using their grade, class, number and name. Finally, we designed and implemented the Web-based Assessment System for Informatics education on the basis of PBA model; PAS(PBA-based Assessment System).

The previous studies regarding the usability evaluation of e-government web sites focused only on deriving affecting factors and variables. They did not find the relationship of usability, user satisfaction and revisiting. The objective of this paper is to find the causal effect how the usability of e-government web sites affect to the user satisfaction and the revisiting attitude. no scope of e-government web sites included the portal site and ie liked web sites. We developed a structural equation model and performed a user test. As a result, a perceived usability affected the revisiting, but it did not intermediate the user satisfaction.

The purpose of this study is to provide a cost effective usability test model for business web site development. In this study, we present a usability test model that combines Concurrent Think Aloud, performance measurement, coaching method, and remote test method. Testing target was the consortium website of electronic information joint licensing. Test participants were actual users selected by their task roles and proficiency in different levels. We improved the system by reflecting the results of user test analysis and re-tested usability test again. The result showed that usability of all participants was improved in the aspect of the time required and the complexity of mouse trajectory. It is expected that the usability test model presented in this study can be used to cost-effectively evaluate and analyze business web sites. We suggest that research various usability test model considering the characteristics of websites.

This article describes the process involved in usability testing a agricultural information Web site. In addition to determining the goals and requirements for the agricultural information Web site, a user and task analysis was conducted for defining the its user base and the types of tasks which users might be performing at the site. Usability testing methods with close observation and in-depth interviews provided fresh insights about how users are interacting with the agricultural information Web interface as they approach various information seeking tasks. This study uncovered problems related to unclear terminology, improper interface, location for navigational links, need for context sensitive help, built-in redundancy, and clear and consistent navigation.

The interaction between web site and it's user is more active and free than that of any other interface environment. Consequently, it is very important that user interface environment must be fully considered in web site development process. In this study, first, web interface environment and it's features are examined, then web usability test techniques are analyzed, and on the basis of the results, new tool for visualizing various responses and patterns of web site user is developed. Finally, by applying newly developed tool to usability test process of an internal hub site and analyzing the results, effective methods for visualization and evaluation of using patterns of web site are suggested.

Currently, usability tests for web sites with representative users are conducted in laboratory environment that disturbs subjects' natural behavior. These test methods are inefficient for tests that require large number of subjects, because experimenters and subjects should be located in the same place at the same time during the test. In this study, a remote usability test tool, called 'RIO' has been developed to cope with these laboratory-based experiment problems - the 'synchronism' and the 'unnatural environment'. The tool is separated into three parts: 'Project Manager', 'Remote Interaction Observer', and 'Interaction Analyzer'. 'Project Manager' sets up overall experimental parameters and actual tasks to be peformed by subjects. 'Remote Interaction Observer', endued with Microsoft Internet Explorer Control, is a modified Web Browser which records user interactions, screen images and elaborate browser events while subject performs given tasks. This module is distributed to subjects as an installable software package. When they finish all the tasks, the captured interaction data is compressed and sent to 'Interaction Data Server' automatically. 'Interaction Analyzer' visualizes interaction data from the 'Interaction Data Server'. It also generates project-scope statistics which facilitate discovering peculiar cases among interaction submissions.

The purpose of this study was to investigate the improvement of the educational web service by using of usability test. For this purpose, a case study was performed with three teachers. They solved three problems, which were linked to the usability of educational web site, with think-aloud. All their actions in the screen and their verbalizations were recorded as computer files. Recoded data were analyzed with the task-performance time analysis, behavior code analysis, and problem behavior graph analysis. From the result of analysis, five improvement strategies were proposed for the development of EDUNET which is an educational information service system and a national teaching & learning center.
