New visualization systems for large and complex datasets are emerging and 3D Virtual Environments turn out to be a relevant solution. Interaction tasks in these 3D VE have been defined, especially to support evaluation of these applications. Nevertheless there is a lack of unified protocol to assess these elementary tasks in this context. Moreover it can be complex to determine the appropriate technique to perform these tasks as there is a lack of reference data. A standard is available for 2D pointing task, but there is no equivalence in 3D. In this paper, we propose an adaptation of this standard to a pointing task in a 3D VE. We detail our protocol and an instrumentation, which aims at assessing performance, comfort of techniques and satisfaction of users. We also present results of a user experimentation conducted according to this standard’s adaptation.
