Interactive analytical tool for usability analysis of mobile indoor navigation application

Mobile navigation applications are the ones that must be tested in real environment in order to show their usability problems. Preparation of the study in real environment is complex issue and so is the analysis of the collected data from such study. Therefore we performed usability study of mobile navigation application for visually impaired users and implemented a set of visualization plugins for IVE tool. IVE tool and visualization plug-ins were used for pre-processing and for visual analysis of collected data from the usability study of mobile indoor navigation application. We found that with IVE we were able to find approximately same amount of usability issues as without this tool, but the IVE tool increased the speed of preprocessing and annotation creation i.e. the time necessary for the analysis has been reduced.
