Project title: Feasibility of Performing Real-Time Experiments in Virtual Reality Using Time Study.

(2005)

Abstract

Virtual Reality, or Artificial Reality, is a technology to digitally simulate reality. It provides a sense of presence through immersion and interaction. Creating an interactive experience, a difficult challenge, is addressed by this technology. Virtual reality provides an opportunity to the user to be immersed in the artificial computer created world and explore as in reality. The success of virtual reality has been associated with the sense of presence experienced by the users. This research aimed to find out whether experimental task duration data collected in virtual and real environment can be equal. A palletizing experiment was conducted in virtual and real environments. Methods Time Measurement (MTM-l) and time study analysis was performed to find the basic motion and standard time for the experiment in both the environments. A modified pre-study with two factors and a modified presence questionnaire with seven factors were administered to the subjects to measure the feeling of presence in the virtual environment. Time and questionnaire data was collected for 14 subjects and analyzed statistically. The subjects partially agreed to the feeling of presence and the presence factors had reliability from 75% to 90%. The time data collected in both the environments differed significantly. It took four times more time than the real environment time to perform the same experiment in virtual environment
