Haptic interpersonal communication is commonly used to salute, to congratulate, or indirectly to manipulate heavy objects. However, the haptic feedback is missing from the common communication systems. Recent developments in telecommunications and computer capabilities have made possible the use of haptic feedback in collaborative virtual environments. Collaborative virtual environments are a promising solution to facilitate remote work collaboration. They have many applications like: military training, engineering design, e-learning or video games.Nevertheless, users of collaborative virtual environments have to face several issues. First, interacting with a virtual environment is not a straightforward task. Navigate and manipulate objects in a virtual environment requires a good mental representation of space. Secondly, remote collaboration limits the communication quality because even the best video conference system can't support all the richness of a face to face communication. Information available on the partners are reduced thus coordinate actions between users become a complex task.The aim of this thesis is to propose visual haptic interactions to simplify coordination and increase mutual awareness between the users. Through the improvement of coordination and mutual awareness an increase of team performance and work efficiency is expected.Three kind of fundamental 3D interactions are addressed in collaborative context: the coordination of selections, the setting of selections and the manipulation of objects. For each of these three of fundamental interactions, several methods of interaction and tools of coordination are proposed and assessed.The findings of this thesis highlight the strengths and the weaknesses of the closely coupled method of interactions. The results of the experiments also confirm the importance of haptic communication in remote collaboration.
