Abstract
The area of data visualisation and computer graphics in general is evolving constantly. There remain numerous challenges to solve in the context of data visualisation in VR or AR. In this work, I argue that 2D and text will be at the core of data visualisation for the foreseeable future. Hence, new visualisation techniques for 2D, 3D non-VR or AR applications may support overview and navigation tasks using novel approaches that combine both 2D and 3D techniques. Also, they should be able to scale arbitrarily from a design perspective to prevent visual clutter and a technical perspective to load only the relevant parts of the tree. Moreover, they may be designed utilising a user-centred approach, which does include an attempt to understand the needs of potential users. This thesis describes a user-centred design, development and evaluation of such a new technique to visualise and interact with hierarchical data. In comparison with existing techniques for visualising hierarchical data my novel method is the first to utilise a user-centred design approach derived from user experience (UX) design. Based on the identified user needs, I introduce a new design metaphor and a novel design derived from it. The novelty of my design stems from the fact that it visualises nodes in detail while also being scalable without introducing visual clutter. Also, it is the first technique for hierarchical data to be designed from the start for both mobile and PC devices. It also introduces a novel concept to offer a classic list based 2D navigation view by dynamically fixating the camera in a native 3D view. This approach combines the benefits of a 3D overview with 2D navigation in just one view where a switch between the modes is simply realised by moving the camera and scaling the node labels. The thesis presents two main practical contributions. The first one is the identification of actual user needs in the context of viewing and interacting with hierarchical data focussing on file and folder management. The second one is the design and development of a scalable technique to visualise and interact with hierarchical data.
