Information Visualization for Mobile-Based Disability Test Applications

As part of the development of ICT convergence technologies for special education, we implemented a mobile-based disability test application. In this paper, we studied an information visualization method that uses a graph to optimize the display on the screen of mobile devices. The implemented application properly divides the screen of the mobile device, and the test scores obtained from the results of the disability test are displayed in a graph that can be moved left and right using the GraphView library. Test comments are also displayed in a table format that can be simultaneously moved up and down. This provides efficiency to users due to the large amount of data that can be represented.
