The importance of usability evaluation is increasing in developing the system(or product). Many usability measures and test methods have been developed in the fields of ergonomics and cognitive engineering. A systematic usability effort using established methods may be qualify as usability engineering. In this paper, general aspects of the usability engineering are introduced, and application methods of usability engineering model based on product's life cycle are presented.

This paper reports results of a recent survey of 184 Information Technology (IT) development practitioners and 90 User Interface (UI)/usability practitioners. This survey covered a broad range of issues including the respondents' profile, current development environment, usability and user-centered design (UCD) adoption issues in IT development practice, overall assessment of usability/UCD, and the most widely used usability/UCD methods and techniques. The results of this study are expected to provide an empirical basis for usability and UCD planning, training, adoption and execution in IT industry.

The paper sets the goal as understanding relationship between usability and subjective preference with the cross- cultural comparison between korea and Japan. Total 42 Korean and japanese housewives participated in the experiment where subjects evaluated their subjective preferences on 16 different variations of computer-simulated microwave ovens. In additions, subjects also performed usability testing over 9 different microwave ovens with 6 different tasks given to users. Subjective preferences and usability were analyzed by Conjoint analysis to identify relative importance of features. The results showed that, in case of Korean subjects, subjective preference has positive relationship with usability (i.e. aesthetically good product also showed better performance in usability testing).However, Japanese subjects showed the tendency that subjectively preferred products are not necessarily evaluated good in usability testing (i.e. god aesthetic is one thing and high usability is another). this difference leads the speculation that culture plays a role in balancing the relationship between aesthetic and functionality.

Although the concept of usability has been well defined in the software usability engineering area, it is not appropriate to apply the same concept directly to the consumer electronic products. A new concept of usability appropriate for evaluating consumer electronic consumer electronic products was suggested in this study. It is characterized by integrating both the performance and the impression factors. Based on the concept developed, a systematic and integrated methodology for usability evaluation was proposed. The methodology contains four major steps; the development of the measurement methods for evaluating usability attributes, the development of the analysis techniques for the human interface elements, the development of the evaluation method for the usability of human interface elements, and the development of the usability model. The results of this study can be applied to evaluate the usability of various electonic products in a systematic and efficent manner.

Usability assessment has been installed into a wide range of software that focuses on assessing product usage from the user's perspective. Usability assessment of the quality of life technology for individuals with disability is being discussed and tentatively designed which is also expanded to the products for non-disabled people with minor adjustment of the usability assessment protocol. Designing an appropriate usability assessment protocol by referencing the currently available international standards on software usability tests with number of modifications to produce valuable feedbacks is under evaluation process regarding product usability enhancement. The feasibility study on usability assessment protocol into quality of life technologies is presented with discussions on further research.

The importance of usability evaluation is increasing in developing a new system and product. The current approaches for usability evaluation are: the comparative evaluation to measure usability, and the iterative user interface design to find usability problems. This paper pressents three types of characteristics and a set of criteria for usability evaluation. The methodology for criteria-based quantitative analysis of user interface usability is investigated with a view to measuring usability. The fuzzy weighted-checklist method with linguistic variables is used for quantitatie analysis. This analysis provides a quantitative measure, which reflects the degree of excellence of user interface usability during the design and development phases.

교육컨텐츠의 양적 팽창은 필연적으로 질적 개선에 대한 관심을 불러일으킨다. 양적으로 풍부한 컨텐츠가 존재하는 상황에서는 학습자들은 같은 인터넷 정보라도 질 높은 사이트를 찾고자 한 것이고, 개발자나 정보제공자는 이러한 수요에 부응하는 WBI를 제공하여야만 생존이 가능할 것이기 때문이다. 그럼에도 불구하고 많은 사이트들은 아직도 사용자의 입장에서 보다는 개발자 자신의 취향이나 시장논리에 의해서 컨텐츠를 제공하는 경우가 많다. 본 연구는 컨텐츠 개발시 질적 완성도가 높은 WBI를 개발하기 위한 방법의 하나로 Usability Test를 제안하고 그 유용성을 시험하기 위해 수행되었다. 이 과정에서 Usability Test를 위한 한 사례로서 <지층과 화석>이라는 컨텐트가 제작되었으며 그 제작 사례를 통해 WBI 완성도 향상을 위한 Usability Test 의 실천방안들이 논의 되었다.

사용성에 대한 사람들의 관심이 증가하고 있는 반면, 사용성 평가 계획의 수립과 진행, 평가결과의 수집과 분석을 지원하는 시스템은 미비한 실정이다. 사용성 평가는 크게, 사용성 평가 계획 수립, 실제 평가 진행, 평가 후 결과 수집 및 분석의 절차를 가지고 있으며, 본 논문에서는 사용성 평가의 전 과정에서 활용할 수 있는 웹 기반 사용성 평가 시스템을 설계 및 구현하였다. 따라서, 사용성 평가에 참가하는 참가자들은 언제 어디서나 기기에 상관없이 효과적으로 사용성 평가에 참여하고, 사용성 평가 책임자는 평가 관련 문서와 결과 데이터를 보다 효율적으로 관리하고 평가의 전 과정의 진행에서 신뢰도를 높일 수 있는 시스템을 구현하는 데 목표를 두었다. 웹 기반 사용성 평가 시스템은 제품의 사용성 평가를 실제 사용하는 장소에서 바로 수행할 수 있다는 장점과 이동이 불편한 장애인 대상 제품의 사용성 평가에 유용할 것으로 기대한다.

Presented in this paper was to evaluate and improve the usability of a web-based logistics information system. The system was developed for the domestic company to track and monitor its own transportation vehicles and for the customers to check the current location of their packages by using Global Positioning System (GPS) and Short Massage Service (SMS). Since the initial system was developed under a tight schedule set by the company, the system designers and programmers did not focus on the usability of the system but on the functionality. Consequently, some usability problems of the system were discovered during the heuristic usability evaluation. This study was required to solve these usability issues. Usability problems of the initial system were identified and analyzed, and the user's requirements for the system were re-evaluated to meet the company's expectation. Several alternative designs were developed by fitted guidelines and then a updated system was developed. The updated system had an empirical usability test to find how much the initial system was improved from the heuristic evaluation. Two kinds of data were gathered during the tests: objective (completion time and number of errors) and subjects' preference. Data showed the updated system is better than the initial system in terms of usability. Presented in this paper includes introduction of the Usability evaluation, usability engineering process applied in this research, alternative design of GUI, usability test and results.

스마트TV는 컴퓨팅 능력, 방송 및 인터넷 서비스가 가능한 상호작용을 높인 텔레비전이다. 사용성은 스마트TV의 평가요소로 그 중요성이 있다. 사용성 관점에서 스마트TV를 평가하기 위해서는 사용성에 영향을 미치는 요인을 중심으로 한 측정 모델의 개발이 필요하다. 본 논문에서는 스마트TV의 사용성 측정을 위한 AHP(계층적분석과정) 모델과 측정 데이터를 획득하는 방법을 제안한다. 선행연구로부터 사용성에 영향을 미치는 요인을 도출한 후 사용성 점수를 계산하는 수치적 예제를 보인다.
