TY - THES A1 - Jang, Harim T1 - Data visualisation platform for individuals N2 - Various companies have been collecting people's digital footprint by offering free digital services to them. People are aware of it vaguely, it is difficult for them to see what actually the companies have or its value. According to the General Data Protection Regulation, finally, individuals can request their collected data from the companies. Nevertheless, the data has been offered as machine-readable files mostly that individuals cannot understand. Thus, a data visualisation application for individuals was designed to improve these problems in this project. The application was built as low fidelity and high fidelity prototypes and tested with 10 participants through remote usability tests to explore its possibility. In the tests, the target users showed their positive interest in the concept and visual design. Consequently, it clearly showed its potential to improve the situation. However, some participants seemed to worry about sharing their data for donating, or unsatisfied with the basic level of data visualisation. To cope with these issues and to have a better effect, some improvement of interface design, additional introduction screens and advanced data visualisation was suggested as a further improvement for the future.
