Performance of new participants in virtual environments: The Nottingham tool for assessment of interaction in virtual environments (NAÏVE)

There is a need for an assessment tool which reliably distinguishes levels of participant performance in virtual environments (VEs) built within virtual reality (VR) systems. Such screening might be of potential users amongst a company's staff or might be carried out by human factors experimenters prior to the start of experiments in order to provide a base-line of participant competences. The Nottingham Tool for Assessment for Interaction in Virtual Environments (NAIVE) comprises a set of VE tasks and related tests, with appropriate performance criteria levels, covering the main aspects of navigation (viewpoint) control and object manipulation and operation. Trials with test participants enabled performance levels to be set to distinguish good, adequate and poor performers and tests to be distinguished according to whether performance in the general population is evenly spread or is skewed towards success or failure.
