Qualitative Visualization of Distance Information [article]

Jobst Heitzig
2002 arXiv   pre-print
Different types of two- and three-dimensional representations of a finite metric space are studied that focus on the accurate representation of the linear order among the distances rather than their actual  ...  Moreover, a measure of order accuracy is introduced, and some lower bound on the possible accuracy is proved using some clustering method and a result on maximal cuts in graphs.  ...  The aim of this paper is to study more "qualitative" kinds of visualization of distance data.  ...

Towards Computational Cognitive Modeling of Mental Imagery

Jan Frederik Sima, Christian Freksa
2012 Künstliche Intelligenz  
Mental imagery is the human ability to imagine and reason with visuo-spatial information. It is crucial for everyday tasks such as describing a route or remembering the form of objects.  ...  There is, however, little progress on a coherent theory that can sufficiently cover the diversity of the empirical data.  ...  Acknowledgements This paper presents work done in the project R1-[ImageSpace] of the Transregional Collaborative Research Center SFB/TR 8 Spatial Cognition.  ...

Connecting time-oriented data and information to a coherent interactive visualization

Ragnar Bade, Stefan Schlechtweg, Silvia Miksch
2004 Proceedings of the 2004 conference on Human factors in computing systems - CHI '04  
In this context one major challenge is to connect time-oriented data and information to a coherent interactive visualization.  ...  In modern intensive care units (ICUs), the medical staff has to monitor a huge amount of high-dimensional and timeoriented data, which needs to be visualized user-and taskspecifically to ease diagnosis  ...  As a result the visual distance between two values in different quality levels is not proportional to the numerical distance.  ...

Toward a new theory of stereopsis

Dhanraj Vishwanath
2014 Psychological review  
Here I propose an alternative hypothesis that stereopsis is a qualitative visual experience related to the perception of egocentric spatial scale.  ...  However, the perception of depth when viewing a real scene with both eyes is qualitatively different: there is a vivid impression of tangible solid form and immersive negative space.  ...  primary, secondary and tertiary qualitative visual attributes.  ...

Hierarchical Qualitative Clustering: clustering mixed datasets with critical qualitative information [article]

Diogo Seca, João Mendes-Moreira, Tiago Mendes-Neves, Ricardo Sousa
2020 arXiv   pre-print
HQC maintains the original interpretability of the qualitative information present in the dataset. We apply HQC to two datasets.  ...  Using a mixed dataset provided by Spotify, we showcase how our method can be used for clustering music artists based on the quantitative features of thousands of songs.  ...  The dendrogram allows the visualization of the connections and distances between clusters of qualitative values.  ...

Illustrative Visualization of Vascular Models for Static 2D Representations [chapter]

Kai Lawonn, Maria Luz, Bernhard Preim, Christian Hansen
2015 Lecture Notes in Computer Science  
A qualitative study with 15 participants and a quantitative study with 50 participants confirm that the proposed visualization technique significantly improves depth assessment of complex 3D vascular models  ...  Depth assessment of 3D vascular models visualized on 2D displays is often difficult, especially in complex workspace conditions such as in the operating room.  ...  We propose a visualization technique that uses as few colors as possible, see Fig. 1 . To assess the benefit of our visualization technique, we performed a qualitative study.  ...
