Cycling stimulates the human mind and body in manifold ways. However, even on a leisure ride, certain waypoints or destinations must be reached. Therefore, orientation is a crucial task for every cyclist. Vibrotactile systems for cyclists do not clog up the visual and auditory senses needed to experience the immediate environment. However, our lite...

Data volume is increasing steadily. Visualization helps to handle not only the volume, but the ever increasing diversity of data. Visualization gives answers faster and reveals information that would go unnoticed and therefore unused in decision making. The challenge we address in this contribution is how visualizations can be created semi-automati...

Project
VANDA is a joined research project with focus on developing visual user interface for big data driven applications. The project owners are: Technische Universität Dresden – Professur Mediengestaltung, Mercateo AG, Chemmedia AG, and deecoob Technology GmbH. The project is funded by the European Regional Development Fund and the Free State of Saxony. Project description: The internet today offers an overwhelming amount of still growing resources such as websites, images, texts, and videos. The resulting Big Data Problem does not only consist of the handling of this immense volume of data. Moreover, data needs to be processed, cleaned, and presented in a user-friendly, graphical way. The VANDA project addresses the challenges summarized in the four V’s: Volume (huge data amounts in the range of tera and peta bytes), Velocity (the speed in which data is created, processed, and analysed), Variety (the different heterogeneous data types, sources, and formats), Veracity (authenticity and validity of data). Big Data driven interfaces in the VANDA project combine suitable backend and frontend technologies as well as automatic and semi-automatic approaches in order to analyse data in various business contexts. An important aspect is human intervention in developing and training machine learning algorithms (human in the loop).
