On-Screen Navigation for 3D Interaction on Multi-Touch-Displays

A usability test with novice users was conducted on an initial and an improved navigation concept. The tested system was a multi-touch-display using infrared technology with a limit of detecting two touch-points. The task for participants was to navigate through a virtual environment using either a widget or gesture-only based navigation concept. The goal of these tests was to assess which aspects influenced intuitiveness of a system for novice users as well as to collect user expectations. The results of these tests indicated that further investigations would be necessary in certain domains as some conclusions were based on assumptions. However, this thesis gives good insights on different aspects and gives further interesting areas to be explored.
