Download as PPT, PDF1 like413 views
The document discusses an approximation simulator designed to aid in the development of accessible Java Swing applications, catering to individuals with various disabilities, particularly visual impairments. It highlights the simulator's ability to alert developers to accessibility issues within graphical user interfaces and presents two NetBeans IDE plugins that enhance its functionality by providing visual design previews and real-time running capabilities. The future work includes enhancing the simulator's capabilities to support a wider range of impairments and improve the overall accessibility design process.
10 An Approximation Simulator for Designing and Developing Accessible Java Swing Applications
- 1. Dr. Dimitrios Tzovaras Informatics and Telematics Institute Centre for Research and Technology Hellas Greece An Approximation Simulator for Designing and Developing Accessible Java Swing Applications
- 2. Introduction Implemented Impairments Approximation Simulator Conclusions and future work Demo Overview
- 3. ICT based products are used by older people or people with disabilities Non-accessible software applications cause productivity losses Lack of accessibility support tools for developers lead to non fully usable applications by design Introduction
- 4. Tools for Web accessibility assessment aDesigner Color Doctor Visual Impairment Simulator for Microsoft Windows Vischeck WebAIM low vision simulator Cambridge University vision impairment simulator Tools for Java Swing accessibility assessment Sun Java Accessibility Utilities Sun Java Accessibility Helper Introduction
- 5. Existing development tools give little assistance or make it impossible to design and develop accessible ICT Java solutions Approximation Simulator can be used for achieving accessibility design for developing Java Swing applications Introduction
- 6. The tool approximately simulates the difficulties someone with vision or other disabilities face when interacting with Java Swing Graphical User Interfaces (GUIs) Through the tool the developer is alerted for any accessibility errors/warnings the implemented GUI may have Introduction
- 7. Cataract Affecting approximately 18 million of the world population Macular degeneration Affecting approximately 9% of the world population Glaucoma Affecting approximately 10% of the world population Implemented Impairments
- 8. Uncorrected refractive errors Affecting approximately 153 million world-widely Night blindness Affecting approximately 1% of preschool-age children and 8% of pregnant women world-widely Color blindness Affecting approximately 8.5% of male and 0.5% of female of the world population Implemented Impairments
- 9. Retinitis pigmentosa Parkinson’s disease Extreme light sensitivity Implemented Impairments
- 11. The tool gives useful information on any GUI component with possible accessibility problems The tool inherits the Look and Feel (L&F) that was set to the application by the developer The tool can adapt to the high contrast appearance scheme as well as the mouse pointer scheme set by the developer Approximation Simulator
- 12. Windows L&F, “High contrast white”, “Windows Standard (extra large)” Approximation Simulator
- 13. Two Netbeans IDE plugins have been implemented as an extension of the approximation simulator DIAS Preview plugin provides a visual design preview feature that allows developers and designers to realize how their implemented GUI forms are being displayed presents all the detected accessibility errors and warnings of the simulated GUI form presents appropriate description of the potential problems as well as specific guidelines and recommendations on how to solve the detected problems DIAS Run plugin gives the ability to execute and run in real time a Java Swing applications and verify if the included functionalities and components contain any accessibility constraint Approximation Simulator
- 14. The approximation simulator would assist developers, throughout the phases of the whole development process, in creating accessible Java Swing GUI applications Improve approximation simulator capabilities Enhance the simulation outcome Support more impairments Cover more impairments with information and recommendations about problematic GUI components Conclusions and future work
- 15. Demo
