摘要：T his This paper discusses a study carried out on different visual/tactual feedback modes for a novel virtual object manipulation task was undertaken to evaluate the VisiTact system and assess the influence of haptic, visual and augmented feedback on a conventional assembly task. The task consists of grasping an object, placing it against a vertical surface, sliding it over the surface and inserting it into a horizontal hole. The study was conducted with two objectives in mind: to determine the number and order of trials required for any further study, and to determine the number of participants needed for the advanced study. A Mental Rotation Test (MRT) was used in the study. The study recommended that any further study should consider no less than four trial repetitions for each task. Additionally, any extra research on the VisiTact should employ at least thirteen subjects to ensure that the results are adequate for such contact type tasks. However, the order, or randomisation, in which each of the modes is executed, was deemed not to be significant. It was hypothesized that the real task would yield a superior performance over all other modes, and that the participant's performance will degrade as the user's level of presence decreases.
