Mobile learning application developers have to overcome inherent limitations imposed by mobile devices in order to produce usable applications. There are usability guidelines available to assist in the design process but with technological improvements, these guidelines should be updated and extended. In this research, we proposed an updated usability guideline to assist in the design process of mobile learning applications. A systematic analysis of seventeen usability studies on mobile learning application was conducted, listed usability problems were extracted and analyzed to formulate new usability guidelines and subsequently the guidelines were updated. The validation results indicate that the updated guideline helps to achieve a higher level of usability as compared to previous guidelines.

In the last 15 years, since the Agile Manifesto emerged, many researchers and professionals have attempted to associate agile methodologies with Usability and User Experience (UX). This association happens to create a model that allows for delivering valuable software. However, most of the approaches identified in the literature that combine these concepts demand a lot of knowledge, cost, time, and, resources. Therefore, it is necessary to develop a more accessible technique and help in the cost and the deadline of the project. For this reason, we created a technique that integrates the most popular agile technique, prototyping, with two of the most important software quality criteria, Usability and UX. As a result, the technique called "User Experience and Usability Guideline for Agile Project" (UXUG-AP) has guidelines focusing on Usability and UX characteristics which support the software design. The technique was designed to be used by agile teams, independently of the amount of resources, project size, and the agile methodology adopted.

Recent years we have witnessed major advancements in technologies that support the children that have been diagnosed with the autism by the increasing number of the application to enhance their ability in communication, understanding and interface with others. There are increasing numbers of a new mobile application that can be found on the market today, unfortunately, many of them are difficult to use and learn by the autistic children. This is due to the lack of usability guidelines for mobile application and relatively unexplored and unproven. This research will propose usability guidelines for interface design of mobile application for autism. The objectives of this research are to identify existing usability factors that have been currently used to design the interface of mobile application for autism and to review the usability guideline to design the interface of mobile application for autism. This project will be conducted in three phases and mixed method involving observation and interview will be applied. The finding of this study is to identify compatible usability elements for designing mobile application user interface for autistic children.

Social Networks are playing an important role in Education. However, many existing ones lack on ergonomics, which directly affects their potential as learning platforms. For this reason, pedagogical usability is of central importance during the development, as well as in the process of maintenance of educational social applications. As a consequence of incomplete and uneasy to use checklists for similar applications, as well as the nonexistence of usability guidelines for social networks as educational environments, this paper presents the first steps of a new usability guideline list. Feedback from the validation show that our guidelines are perceived as well constructed by experts.

The current efforts to specify an usability guideline for accessible mobile applications are sparse and they are still far to present a concrete pattern. Our previous work carried out a broad survey to consolidate the findings of these efforts in a unique list with 36 requirements, 13 of them focused on vision impairments. In this paper we show the results of an observation-based analysis involving visually impaired volunteers, whose aim was to complement this review and confirm if the lack of these requirements in fact affects the use of mobile applications.

In this paper, we propose a contents design guideline for mobile Internet terminals (browser phones) such as i-mode phones. This guideline shows specs of the browser phones in Japan, and considers situations and needs of common users. Then we define design rules.

International audience; Very Large Web Sites are a particular category of web sites where the potential of traditional evaluation process for ensuring usability is significantly contracted by the size of the web site. Since this kind of web site is authored, designed, evaluated, and maintained by a wide variety of people who have specific information demands over a huge set of web pages, we believe that Universal Design principles should be integrated into the current approach for managing such web sites. We propose to support Universal Design principles by integrating related guidelines into a global approach for managing Very Large Web Sites. This approach is supported by Extended Bobby, an extension of the Bobby tool that provides (i) evaluation on demand ; (ii) a repair tool that proposes to authors of web pages new HTML code fixing usability problems that Extended Bobby itself has merely identified and explained ; (iii) a usability site tracker that keeps track of usability problems of the web sites, automatically sends e-mails to authors with the repair proposal, and helps site managers and webmasters to manage the pages evolving in time.; Les sites web de très grande taille forment une catégorie de sites web pour lesquels l'évaluation classique de leut utilisabilité est sérieusement réduite par la taille du site web. Ce genre de site web est rédigé, conçu, évalué et maintenu par une large variété de personnes qui ont chacunes des exigences informationnelles différentes sur un énomr ensemble de pages web. Nous pensons dès lors que les principes de conception universelle peuvent bien être intégrés à une démarche de gestion de tels sites. Nous proposons pour cela une démarche soutenue par le logiciel Bobby Extended, une version étendue du logiciel Bobby qui procure une évaluation à la volée, un réparateur des règles ergoomiques enfreintes pour une page web suite à une évaluation automatique et un suiveur d'utilisabilité des problèmes ergonomiques détectés, notamment par l'envoi automatique de messages invitant à reataurer les règles enfreintes, ce qui devrait aider les gestionnaires de sites web et leurs vaguemestres.
