11 Java User Interface Libraries for Developing Mobile Applications

5,028

Published on

The current presentations will present interface concepts and technological solutions in current and future mass-market products and services of the mobile devices/applications market segment, up to which level and for which persons, as anticipated in the context of ÆGIS Integrating Project (Grant Agreement: 224348) of the 7th Framework Programme. These interface concepts can be used for designing and developing accessibility and accessible applications. ÆGIS aims to embed support for accessibility through the development of an Open Accessibility Framework (OAF), upon which, open source accessibility interfaces and applications for the users as well as accessibility toolkits for the developers will be built. Within ÆGIS, three mainstream markets are targeted, namely the desktop, rich Internet applications and mobile evices/applications market segments. It is obvious that achievements already made in ICT cannot be ignored; however need to be more “accessible”, more “open” whenever possible, and, most of all, embedded, built in the application from the beginning. It should be taken into account, for example, that even there are access solutions available in cell phones and PDA’s, still, they require special-case approaches and reverse engineering on the part of the expensive Assistive Technology solutions that are limited to only a few disabilities (blindness & low vision). In addition, many of them are “closed”; thus not feasible for 3rd party s/w to be loaded onto them – embedding accessibility support directly is the only feasible option. This paper will focus on which the recommended practices are for embedding accessible interface options in current and future mass-market mobile products and services. This paper describes existing Java user interface libraries and underlines some of their features regarding sound and graphics. These features can be used, modified, adapted or refined in conjunction with Operating System capabilities in order to provide accessibility and accessible support for any application.
