Usability evaluation of virtual reality interaction techniques for positioning and manoeuvring in reduced, manipulation-oriented environments.

This paper introduces some novel interaction techniques based on the concepts of composite positioning and composite manoeuvring (described in the paper). In contrast with other previous proposals, these techniques have been designed and evaluated in the context of a user centred process. The results of this evaluation and some relevant findings for the field of human computer interaction are also described. [ABSTRACT FROM AUTHOR]
