evaluation and communication of personal financial information. Practice- and application-oriented (Type A) Supervised by Prof. Dr. Gerhard Buurman and Dr. Karmen Franinović 2 Visual Instruments for Personal Finances
context Decided to focus on «leasure» and this has impact on the user activities and the visual and functional design of the application. Flesh out the prototypes based on the user activities In order to be able to test interaction techniques and attributes. Too many visualization attributes to consider them all Based on the research questions and considering the user context, the following are most important: Directness, movement, speed and proximity. 5
[a] impact my wealth? How does an increase in [b] impact my wealth? How would my liquidity look like in the case of [c]? Can I afford to buy [d]? When can I afford to increase my spending for [e]? How much do I spend on [f]? How do I have to change my spending to achieve [g]? Do other people spend as much as I am on [h] If I didn't do [i], how would my wealth look like? … 8

simple applications that are able to answer speciﬁc questions individually. Format The right format feels less like work and more like enterntainment, exploration, play, challenge. User Experience The user should feel comfortable navigating his information and answering his questions. 20
principles can be embedded in the information visualization design process. Veriﬁed The design principles are veryﬁed and tested by a group of practitioners. State of the Art The design principles are in line with the current research and literature. 21 Pontis, S., 2010. Methodological approaches for diagramming information. Pontis, S., 2009.

the test environment. Evaluation and iteration of the prototypes and the test environment. Within the next days, I will roll out more experiments to a group of users that I haven’t talked to. Principles Identify the design principles. Formulate how to apply them. Discuss them with the group of practitioners and my mentors. 26
