Tsetse flies Glossina spp. (Diptera; Glossinidae) are blood-feeding vectors of disease that are attracted to vertebrate hosts by odours and visual cues. Studies on how tsetse flies approach visual devices are of fundamental interest because they can help in the development of more efficient control tools. The responses of a forest tsetse fly species Glossina brevipalpis (Newstead)...

A collaborative extension of a visualization system

Casera, Steve ; Nägeli, Hans-Heinrich ; Kropf, Peter

In: 1st International Conference on Distributed Frameworks for Multimedia Applications (DFMA), 2005, p. 176-182

This paper presents an extension of the single-user scientific visualization system ZoomIn to a collaborative system. We discuss the principal challenges of remote collaboration in the case of scientific visualization and present the solutions realized for ZoomIn. The main issues identified include the support of slow/fast network connections, portability, ease-of-use, privacy, configuration of...

Collaboration in scientific visualization

Casera, Steve ; Kropf, Peter

In: 12th International Conference on Computer Supported Cooperative Work in Design (CSCWD), 2008, p. 1091-1096

This paper discusses the key collaborative features of scientific visualization systems. An experiment with several groups of users has been conducted to evaluate the usability and effectiveness of collaborative tools in such a system. In particular, we compared audio and textual communication support for information exchange as well as the use of graphical indicators. Our analysis revealed the...

Visualisation scientifique collaborative

Casera, Steve ; Kropf, Peter (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2007 ; 1949.

La visualisation scientifique est utilisée habituellement pour résoudre des problèmes complexes et analyser des données. La collaboration joue un rôle crucial dans le domaine de la visualisation scientifique. En effet, dans les domaines d’application concernés, il est fréquent que l’on doive recourir aux compétences d’un spécialiste situé à une certaine distance. Dans cette...
