This paper presents our work in mapping the design space of techniques for temporal graph visualisation Weidentify two independent dimensions upon which the techniques can be classified
Recently, much research has focused on developing techniques for the visual representation of temporal graph data This paper takes a wider look at the visual techniques involved in exploratory analysis of such data, considering the variety of sub tasks and contextual tasks required to understand change in a graph over time, and the visual techniques which a
Augmented reality (AR) enables users to retrieve additional information about the real world objects and locations Exploring such location-based information in AR requires physical movement to different viewpoints, which may be tiring and even infeasible when viewpoints are out of reach In this paper, we present object-centric exploration techniques for ha
We explore how the availability of a sensemaking tool influences users knowledge externalization strategies On a large display, users were asked to solve an intelligence analysis task with or without a bidirectionally linked concept-graph (BLC) to organize insights into concepts (nodes) and relations (edges) In BLC, both nodes and edges maintain links to
In this paper, we provide the second part of the study of the pseudo-permutations We first derive a complete analysis of the pseudo-permutations, based on hyperplane arrangements, generalizing the usual way of translating the permutations We then study the module of the pseudo-permutations over the symmetric group and provide the characteristics of this ac
Through the synthesis of gathered user research data, interaction designers are able to generate design proposals Logging user interactions with a software provides a rich set of data that can give further insights into users behavior We present a case study of visualizing interactions log files of the manual tumor contouring task We identify two types

Given an arrangement of lines in the plane, what is the minimum number c of colors required to color the lines so that no cell of the arrangement is monochromatic? In this paper we give bounds on the number c both for the above question, as well as some of its variations We redefine these problems as geometric hypergraph coloring problems If we define $\Hl
In their 2009 paper, Corneil et al design a linear time interval graph recognition algorithm based on six sweeps of Lexicographic Breadth-First Search (LBFS) and prove its correctness They believe that their corresponding 5-sweep LBFS interval graph recognition algorithm is also correct Thanks to the LBFS structure theory established mainly by Corneil et
Recently, there has been an interest in methods for filtering large scatter plot spaces for interesting patterns However, user interaction remains crucial in starting an explorative analysis in a large scatter plot space We introduce an approach for explorative search and navigation in large sets of scatter plot diagrams By means of a sketch-based query i

Social media platforms provide a useful source of data for environmental planning In the last years these data have been exploited to perform social behaviour analysis This work uses the huge amount of georeferenced images publicly available on social media as a source of information to infer the behaviour of tourists Visual analytic mapping tools combine
Comparing spatial performance in different virtual reality setups can indicate which cues are relevant for a realistic virtual experience Bodily self-movement cues and global orientation information were shown to increase spatial performance compared with local visual cues only We tested the combined impact of bodily and global orientation cues by having p

Fighting against crime is paramount to any society, maybe more today than ever before Tools to fight and elucidate crime are rooted in forensic science Through the autopsy of a body, we can answer a whole range of questions as to how death happened and come up with explanations and counter-measures so that the same dire circumstance does not happen again

For a brick apart from a few small graphs, Lovász (1987) proposed a conjecture on the existence of an edge whose deletion results in a graph with only one brick in its tight cut decomposition Carvalho, Lucchesi, and Murty (2002) confirmed this conjecture by showing the existence of such two edges This paper generalizes the result obtained by Carvalho et al

This paper addresses important issues in the evaluation of new visualization techniques It describes the principle of quantitative research in general and presents the idea of experimental studies The goal of experimental studies is to provide the base for guidelines, which allow testing of hypotheses that newly-developed visualization solutions are better
Despite numerous recent efforts, 3D object retrieval based on partial shape queries remains a challenging problem, far from being solved The problem can be defined as
