This project aims at deepening the understanding of scale and complexity effects for data analysis in immersive environments. To this end, the scale and complexity space for immersive analytics will be characterised, and effects and limits of scale and complexity dimensions will be quantified. In a combination of methodological work and user studie... |
In this project, we will carry out behavioural experiments using human participants and base our empirical choices on the framework of optimal decision theory as derived from the Bayesian approach. This approach can be used as a tool to construct ideal observer models against which human performance can be compared. |
The goal of this project is to develop new algorithms that allow user-customised graph views and smooth transitions between different types of graph visualisations. |
Computational photography (CP) has in recent years emerged as a vibrant sub-field within visual computing and has brought forth highly creative techniques, expanding the notion of a camera beyond the traditional model. By combining novel optical designs with algorithmic techniques for image reconstruction, CP techniques provide advantages such as h... |
We plan to extend stress-minimisation approaches for general graph layout. Current algorithms fail on specific classes of input graphs, for instance because of scale, diameter, or skewed degree distributions. Moreover, characteristics of the output device and user interactions are generally ignored. Adaptive algorithms shall be developed from quant... |
In this project, we research new methods and techniques for cognition-aware visualisations. The basic idea is that a cognition-aware adaptive visualisation will observe the physiological response of a person while interacting with a system und use this implicit input. Electrical signals measured on the body (e.g. EEG, EMG, ECG, galvanic skin respon... |
Immersive virtual environments (IVEs) simulate real-world scenarios for purposes ranging from entertainment to safety-critical training (e.g., surgery, driving or flying). This project investigates how computationally demanding IVEs can be optimised to ensure realistic user performance, by focusing on how users seek out and process information for... |
Models and metrics of visualisation and interaction techniques can predict the time a person needs to understand presented information and to execute a task. Previous work mainly focused on basic models. What is missing are models and metrics for realistic use cases and novel interactive systems. We will upscale the quantitative investigations of v... |
The goal of the project is to create quantitative methods for the perception-aware representation of 3D virtual cities. We will develop a grammar-based system for the effective visual communication of building-related information via geometric 3D building representations that induce a defined degree of perceptual insight in the observer’s mind. The... |
