The elegance of using virtual interactive lenses to provide alternative visual representations
for selected regions of interest is highly valued, especially in the realm of visualization …

Geovisualization applications typically organize data into layers. These layers hold different
types of geographical features, describe different characteristics of the same features, or …

A replication is an attempt to confirm an earlier study's findings. It is often claimed that
research in Human-Computer Interaction (HCI) contains too few replications. To investigate …

Topic modeling, which reveals underlying topics of a document corpus, has been actively
adopted in visual analytics for large-scale document collections. However, due to its …

Ultra-high resolution wall-sized displays (“ultra-walls”) are effective for presenting large
datasets, but their size and resolution make traditional pointing techniques inadequate for …

Visual representations of time-series are useful for tasks such as identifying trends, patterns
and anomalies in the data. Many techniques have been devised to make these visual …

Since their introduction in the early nineties, Magic Lenses have attracted much interest.
Especially in the realm of visualization, the elegance of using a virtual interactive lens to …

The most common techniques for navigating in multiscale visual spaces are pan, zoom, and
bird's eye views. However, these techniques are often tedious and cumbersome to use …

Magic lenses are popular tools to provide locally altered views of visual data. In this paper,
we introduce the concept of BodyLenses, special kinds of magic lenses for wall displays that …

Targets of only a few pixels are notoriously difficult to acquire. Despite many attempts at
facilitating pointing, the reasons for this difficulty are poorly understood. We confirm a strong …
