Collaborative approach for dynamic adjustment of selection areas in polygonal modelling
Résumé
Collaborative Virtual Environments (CVEs) introduce new working
methods, allowing multiple users to work simultaneously in the
same virtual space from different spatial locations. However, CVEs
are not able to reflect the richness of real world communication. Indeed,
these environments limit the shared situation awareness (SSA
that is the degree of similarity between each members perception
of a same given situation), may lead to a reduction in performance
and efficiency of the group.
Nova et al. [Nova et al. 2006] showed that using awareness tools
improves performance in collaborative task. In fact, these tools provide
relevant information about the position of a partner in the virtual
environment. On the other hand, Endsley and Garland [Endsley
and Garland 2000] pointed out the fact that providing more data is
different from providing more information. Note that defining if a
given information represents a useful data is not straightforward as
it depends on the situation.
This difficulty leads us to propose an alternative approach to improve
SSA and thus to improve working efficiency. Instead of providing
more information about users, we developed an interaction
method which depends on the partners actions. In the context of a
collaborative polygonal modelling, this research proposes a closely
coupled method to adjust the selection area and forces each partner
to be aware of the action and the location of the partner.
