A method for autonomous positioning avatars in a group

In this paper, we describe a method to position a group of avatars in a virtual environment. The method aims at a group setting that seems natural for a group of people attending a guided tour and was developed in particular to assist participants by autonomously positioning their avatars on each stop of a virtual tour. The geometry of the virtual environment is key input, but also engagement of participants and possible social networks are taken into account. Consequently, it may serve to position avatars in similar type of situations

Navigation in REVERIE's Virtual Environments

This work presents a novel navigation system for social collaborative virtual environments populated with multiple characters. The navigation system ensures collision free movement of avatars and agents. It supports direct user manipulation, automated path planning, positioning to get seated, and follow-me behaviour for groups. In follow-me mode, the socially aware system manages the mise en place of individuals within a group. A use case centred around on an educational virtual trip to the European Parliament created for the REVERIE FP7 project, also serves as an example to bring forward aspects of such navigational requirements

A Taxonomy of Best-Reply Multifunctions in 2x2x2 Trimatrix Games

This paper provides an overview of the various shapes the best- reply multifunctions can take in 2×2×2 trimatrix games. It is shown that, unlike in 2×2 bimatrix games, the best replies to the opponents’ pure strategies do not completely determine the structure of the Nash equilibrium set.non-cooperative games;best-reply multifunction;Nash equilibrium
