    The purpose of this research is to produce a messenger applications such as Messenger Translator Applications. Then test the feasibility of the application as an application that makes it easy to translate language or translator in chat communication. The application is developed using Java programming language and integrated with Google Translate API. The function of the Google Translate API as a language translator automatically in the messenger. This study uses research and development method. The steps of the method requirements such analysis, design, coding, and testing. Alpha testing performed by 2 expert software engineering. While beta testing conducted by the respondent as many as 16 students. The analysis technique used is descriptive quantitative analysis techniques. Quantitative descriptive is used to declare the results of the calculation in the form of percentage viability. The results of the analysis showed that the Messenger software Translator Application is valid in terms of correctness and reliability. In alpha testing, software earn a percentage of 90% in terms of functionality and 85% in terms of usability. While proprietary software, according to the user by 89.69% from 83.45% in terms of functionality and in terms of usability. Keywords: application, messenger, translato

    Usability Inspection in Model-Driven Web Development: Empirical Validation in WebML

    Full text link
    There is a lack of empirically validated usability evaluation methods that can be applied to models in model-driven Web development. Evaluation of these models allows an early detection of usability problems perceived by the end-user. This motivated us to propose WUEP, a usability inspection method which can be integrated into different model-driven Web development processes. We previously demonstrated how WUEP can effectively be used when following the Object-Oriented Hypermedia method. In order to provide evidences about WUEP’s generalizability, this paper presents the operationalization and empirical validation of WUEP into another well-known method: WebML. The effectiveness, efficiency, perceived ease of use, and satisfaction of WUEP were evaluated in comparison to Heuristic Evaluation (HE) from the viewpoint of novice inspectors. The results show that WUEP was more effective and efficient than HE when detecting usability problems on models. Also, inspectors were satisfied when applying WUEP, and found it easier to use than HE.Fernández Martínez, A.; Abrahao Gonzales, SM.; Insfrán Pelozo, CE.; Matera, M. (2013).

    Systems development methods and usability in Norway: An industrial perspective

    This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2007 Springer Berlin HeidelbergThis paper investigates the relationship between traditional systems development methodologies and usability, through a survey of 78 Norwegian IT companies. Building on previous research we proposed two hypotheses; (1) that software companies will generally pay lip service to usability, but do not prioritize it in industrial projects, and (2) that systems development methods and usability are perceived as not being integrated. We find support for both hypotheses. Thus, the use of systems development methods is fairly stable, confirming earlier research. Most companies do not use a formal method, and of those who do, the majority use their own method. Generally, the use of methods is rather pragmatic: Companies that do not use formal methods report that they use elements from such methods. Further, companies that use their own method import elements from standardised methods into their own

    Adaptive development and maintenance of user-centric software systems

    A software system cannot be developed without considering the various facets of its environment. Stakeholders – including the users that play a central role – have their needs, expectations, and perceptions of a system. Organisational and technical aspects of the environment are constantly changing. The ability to adapt a software system and its requirements to its environment throughout its full lifecycle is of paramount importance in a constantly changing environment. The continuous involvement of users is as important as the constant evaluation of the system and the observation of evolving environments. We present a methodology for adaptive software systems development and maintenance. We draw upon a diverse range of accepted methods including participatory design, software architecture, and evolutionary design. Our focus is on user-centred software systems

    Finding and Resolving Security Misusability with Misusability Cases

    Although widely used for both security and usability concerns, scenarios used in security design may not necessarily inform the design of usability, and vice- versa. One way of using scenarios to bridge security and usability involves explicitly describing how design deci- sions can lead to users inadvertently exploiting vulnera- bilities to carry out their production tasks. This paper describes how misusability cases, scenarios that describe how design decisions may lead to usability problems sub- sequently leading to system misuse, address this problem. We describe the related work upon which misusability cases are based before presenting the approach, and illus- trating its application using a case study example. Finally, we describe some findings from this approach that further inform the design of usable and secure systems

    Enterprise Experience into the Integration of Human-Centered Design and Kanban

    he integration of Human-Centered Design (HCD) and Agile Software Development (ASD) promises the development of competitive products comprising a good User Experience (UX). This study has investigated the integration of HCD and Kanban with the aim to gain industrial experiences in a real world context. A case study showed that requirements flow into the development process in a structured manner by adding a design board. To this end, the transparency concerning recurring requirements increased. We contribute to the body of knowledge of software development by providing practical insights into Human-Centered Agile Development (HCAD). On one hand, it is shown that the integration of HCD and Kanban leads to a product with a good UX and makes the development process more human-centered. On the other hand, we conclude that a cross-functional collaboration speeds up product development.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015-71938-RED

    A Measurement-Driven Process Model For Managing Inconsistent Software Requirements

    Full text link
    Inconsistency is a pervasive issue in software engineering. Both general rules of inconsistency management and special case-based approaches to handling inconsistency have recently been considered. In this paper, we present a process model for handling requirements inconsistency within the Viewpoints framework. In this process model, when an inconsistency among viewpoints is detected, a set of candidate proposals for handling inconsistency will be generated using techniques fromMulti-agent automated negotiations. The proposals are then prioritized using an integrated measurement of inconsistencies. The viewpoints involved in the inconsistency will then enter the negotiations by being presented with the candidate proposals and thus selecting an acceptable proposal based on the priorities associated with each candidate proposal. To facilitate usability, in our process, we assume that the natural language requirements statements are first translated into corresponding logical formulas using a translator software. Moreover, the candidate proposals for handling inconsistency are also translated back from formal logic into natural language before being presented for selection
