Object-oriented software development has proven effective for systems development, but the creation of reusable and changeable software architectures is still a challenging task. Design patterns capture the expertise for reusable design solutions, but there is no methodical approach to providing conceptual design building blocks in tangible and composable form. Design components have been sugge...

Fisheye views use distortion to provide both local detail and global context in a single continuous view. However, the distorted presentation can make it more difficult to interact with the data; it is therefore not clear whether fisheye views are good choices for interactive tasks. To investigate this question, we tested the effects of magnification and representation on user performance in a ...

Interactive exercise assistants support students in practicing exercises, and acquiring procedural skills. Many mathematical topics can be practiced in such assistants. Ideally, an interactive exercise assistant not only validates final answers, but also comments on intermediate steps submitted by a student, provides hints on how to proceed, and presents worked-out examples. For these purposes,...

The software package DNAVis offers a fast, interactive and real-time visualization of DNA sequences and their comparative genome annotations. DNAVis implements advanced methods of information visualization such as linked views, perspective walls and semantic zooming, in addition to the display of heterologous data in dot plot-like matrix views.

We investigate secondary view techniques in a multimodal VR environment for dataset exploration and interpretation. Secondary views, such as 3D lenses or mirrors, can present alternative viewpoints, different filtering options, or different data sets. We focus on 3D views showing surface features that are hidden in a main view. We present different view techniques, including new variations, and...

In this paper, we present an artist’s tool, MultiCam, to design abstract paintings with a simple, interactive and intuitive rendering technique. This interactive rendering system is inspired by multiple view ray-tracing techniques that is based on the cubist principle of multiple views and collage.

SimVis is an interactive research implementation of a visual analysis scheme which we developed for the feature-based assessment of flow simulation data. It is based on the concept of multiple, linked views of different kinds, including views from information visualization such as adapted scatterplots and histograms. In this paper we present an extension to our interactive visual analysis frame...
