Summary
C.A. Blok - Monitoring of spatio-temporal changes: characteristics
of dynamics for visual exploration
Keywords: dynamic visualisation, characteristics of dynamic
phenomena, theory
In the context of a research about application of dynamic visuali
sation parameters in animations for monitoring purposes, this pa-
per reports on characteristics of dynamic phenomena. A frame-
work to describe characteristics in general concepts is proposed.
The framework will be used to categorise a variety of phenomena
in the physical environment. Ifit proves to be a suitable frame of
reference, dynamic visualisation parameters will be linked to the
characteristics. The goal is to design representation methods and
interaction tools that prompt thinking about the processes at work
and about spatio-temporal relationships by domain experts who
perform monitoring tasks. The nature of monitoring tasks is consi-
dered in the proposed framework. Explicit attention is paid to
context-sensitivity and to the description of the temporal beha-
viour of dynamic phenomena. Finally, some of the prospects and
Problems ofthe research are discussed.

C.A. Blok - Monitoring des changements dans l'espace et le

sualisation
Mots-cles: visualisation, caracteristiques des phenomenes dy

L 'auteur analyse, dans le contexte d'une recherche sur l'application
des parametres de visualisation dynamique animee en vue de 'mo
nitoring. II s 'agit de fournir un cadre de concepts generauxpour la
Classification des divers phenomenes du milieu physique. S'il s'agit
d'un cadre de reference valable, la visualisation dynamique des
parametres pourrait etre en fionetion de ces caracteristiques. L 'ob-
jectif en est realiser des outils et des methodes de representation et
d'interaction facilitant la reflexion sur leprocessus de travail et sur
les relations spatiales et temporelles entre les experts de divers do-
maines de monitoring, dont les dijferentes täches sont analysees en
detail, dans le cadre propose. Une attention particuliere est consa-
cree l'appreciation du contexte et a la description du comporte-
ment temporel des phenomenes dynamiques. Enfin, l'auteur es-
quisse des perspectives d'avenir et des sujets de recherches.
