| Abstract [eng] |
A virtual learning environment has become the main learners' communication and content learning delivery channel in distance education. Evolution of mobile technologies, diversity of devices, used for accessing the web, and different users' needs bring new challenges for the developers of the user interface of a virtual learning environment. With different users' needs and technological possibilities comes a necessity of universal, transformable, modular and accessible user interface. Creation of the user interface for virtual learning environment „Moodle“ is a complex process. The editing and testing of theme template in „Moodle“ environment is time consuming and it is determined by the system's architectural features. Considered that, a modular user interface design system containing blocks and elements, that can be joined together, were planned for the project. A CSS methodology that determines a rules of display of the components was used. The evaluation of the virtual learning environment was made according to W3C WCAG accessibility guidelines. The evaluation of the accessibility of „Moodle's“ main theme „Boost“ user's interface components was made. New improved code was introduced for the components where accessibility fails were detected. For the creation and management of the design system a „Fractal“ tool was adopted. New components with improved accessibility were transferred from „Fractal“ to the „Boost“ child theme. By adopting the design system the process of the creation, testing and updating of the „Moodle“ user interface was improved. |
