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.

In this paper, an evaluation method of fracture toughness on interface cracks has been investigated under various mixed-mode conditions of the bonded scarf joints. Two types of the bonded scarf joints with an interface crack were prepared to analyze the stress intensity factors using boundary element method(BEM) and to perform the fracture toughness test. From the results of fracture toughness experiments and BEM analysis, an evaluation method of fracture toughness on interface cracks in the bonded components of dissimilar materials has been proposed and discussed.

In this paper, an evaluation method of fracture toughness on interface cracks was investigated in friction welded dissimilar materials with interfacial edge cracks. To establish a reasonable strength evaluation method and fracture criterion, it is necessary to analyze stress intensity factor under the load and residual stress condition on friction welded interface between dissimilar materials. The friction welded specimens with an edged crack were prepared for analysis of stress intensity by using the boundary element method (BEM) and the fracture toughness. A quantitative fracture criterion for friction welded STS 304/SM 45C with interface crack is suggested by using stress intensity factor, F and the results of fracture toughness experiment.

This paper proposes a method to select essential elements in a human evaluation model using the Choquet integral based on fuzzy measures and applies the model to the evaluation of human interface. Three kinds of concepts, Increment Degree, average of Increment Degree, Necessity coefficient, are defined. The proposed method selects essential elements by the use of the Relative necessity coefficient. The proposed method is applied to the analysis of human interface. In the experiment, (1) a warning sound, (2)a color vision, (3) the size of working area, (4) a response of confirmation, are considered as human interface elements. subjects answer the questionnarie after the experiment. From the data of questionnaire, fuzzy measures are identified and are applied to the proposed model. effectiveness of the proposed model is confirmed by the comparison of human interface elements extracted from the proposed model and those from the questionnarie.

The goal of this study is to find ways to improve the open access publication support service platform through the usability evaluation of the publishing manager interface among the AccessON journal repository interfaces, which is an open access publication support service platform. Various documents and cases related to open access publishing and usability evaluation in order to answer three research questions: collection of user experience responses of interface, extraction of issues and improvement points, and analysis and derivation of suggestions for other open access publication support service platforms. Responses to the experience of using the publishing manager interface were collected through surveys and focus group interviews. Combining this, it was possible to present the results of the usability evaluation of the AccessON journal repository interface through various numerical information. The results of the usability evaluation made it possible to propose issues and improvements to the AccessON journal repository manager interface, and finally, it was possible to derive suggestions for the open access academic publishing support service platform to be developed later.

The use of games using smartphones have become universal, and the market share of MMORPG among various game genres shows an uptrend. However, MMORPG requires complex interface in view of the genre characteristics, and therefore, there are difficulties in building interface for efficient game play. This study analyzed game interface characteristics to suggest MMORPG game interface suitable for the mobile environment, and carried out a questionnaire survey evaluation on the usability of fight, exploration, character and transaction interfaces targeting 12 users. To quantitatively evaluate the subjective questionnaire survey results, this study analyzed a correlation between the characteristics of game interface and popularity using AHP. As a result, there was a close correlation between game selection & popularity and interface, and this study ascertained that interface development through game interface usability evaluation using AHP was possible.

This paper deals with the ways that can improve the reliability of the course evaluation system based on reformation of the system and design of user interface for the practical applications. In the reformation of the system aspect, there are the improvements of the course evaluation questionnaires and the feedback of course evaluation to the lecturers. In the design aspect, a computer screen of the graphic user interface is redesigned to reflect the reformation of the system aspect issues. The results show the effectiveness in the reliability improvement.

This paper investigates the user interface design principles and evaluation methods with the corresponding examples. Some of these principles are: 1) focus on the users and their tasks, not the technology; 2) consider function first, presentation later; 3) conform to the users' view of the task; 4) do not complicate the user's task; 5) promote learning; 6) deliver information, not just data; 7) design for responsiveness; and 8) try it out on users, then fix it. In addition, this paper deals with the general human computer interaction issues as the basis for introducing the user interface design principles.
