Diploma Thesis: "Arc Diagrams" for pattern visualization in multivariate time-dependent data

The effective display of time-dependent data is one of the major tasks in information visualization. There are many expressive techniques known, which however are often limited to the pure visualization of data. To gain insight into the data, support for higher order visualization tasks, like the detection of patterns, is required. However, an explicit indication of repeated patterns within the data is only rarely considered.

“Arc Diagrams” is a technique to visualize repeated patterns in strings (i.e., 1-dimensional data). The goal of this thesis is to extend the “Arc Diagrams” in order to make them applicable to visualize multivariate time-dependent data. Addressing this challenge, “Arc Diagrams” are classified and assessed in order to support the selection of eligible new concepts. Several new concepts, like an improved pattern search strategy and enhanced visual representations, are implemented in an interactive application capable of visualizing multivariate time-series data by means “Arc Diagrams”.

Student Research Project: "Usability of SVG (Scalable Vector Graphics) for information visualization on mobile devices."

In this student research project it is analyzed if SVG is suited for visualization of relational data sets.It is tested how the limited capability of mobile devices is responsible for the number of still as interactive understandable SVG Primitives. Furthermore it is clarified how complex a SVG Presentation may be. In line with this, the interaction-possibilities also play a role. In addititon it is checked out which interface is proper for the connection of database and SVG. (direct database connection, software connection) A suitable connection is implemented and is the basis for further researches introduced at the end of this work. [STUDIENARBEIT (german)]

Seminar "Ubiquitous Computing"

To reach a seamless integration of computer support into everyday life is one of the current challenges in computer sciences and Human-Computer interaction. My challenge was to open up the topic "Sensors in the field of "Ubiquitous Computing" [lecture (german)] & [summary (german)]

Technical Documentation

Within the reading "Technical Documentation" the task to write a "manual of instruction" was assigned. This manual describes an application scenario for the "Boehringer DUS 400 ti" turning machine. [manual (german)]

Animation of Ancient Scenarios

Within the reading “Geometric Modelling” the task to reproduce ancient scenarios with the software “3D Studio Max” was assigned. This report describes the process of modelling the “Marienkirche” of Rostock.[DOWNLOAD]

Work Experience Report

This reports describes my 18 weeks lasting practical training at the east creative GbR in Stralsund. Due to the fact that this company offers web ideal solutions (design, hosting, programming) for their customers, I dealt with the programming of graphical web-tools.[DOWNLOAD]

Bachelor Thesis: "Development of a concept for appropriated labelling of information objects."

Nowadays an effective visualisation of information structures is particularly hampered by the fact, that there are only little algorithms for hierarchy labelling. In this paper a concept for appropriated labelling of information objects, considering the nodes of the magic eye view, a focus+context technique for hierarchy-visualisation, as an example, is worked out. The concept is realised in 2D on an Personal Digital Assistant (PDA).[DOWNLOAD] [Defence]
