This retrospective study examined the levels of appreciation (applause) given by clients to Human Factors/Ergonomic (HFE) specialists after they have modified the systems of work. Thirteen non-academic projects were chosen because the HFE interventions involved changed the way workers work at their workplaces. Companies involved range from multi-national corporations and military organizations with...
This paper reports on the types and magnitudes of localization errors of simulated binaural direction cues generated using non-individualized, head-related transfer functions (HRTFs) with different levels of complexity. Four levels of complexity, as represented by the number of non-zero coefficients of the associated HRTF filters (128, 64, 32, 18 non-zero coefficients), were studied. Experiment 1...
Image latencies occur when a virtual environment (VE) responds to hand movements of its operator. A study has been conducted to investigate the effects of, and interactions among, hand movement related image latencies, target distance, and target width on discrete manual control tasks in a VE. In the presence of latencies, completion times of hand movement tasks have been found to obey Fitts' law...
