Paper Abstract

The objective of this study is to compare human performance in executing tasks with a helmet- mounted display interface using different visual cues of depth perception. The study involves two experiments, the first, with direct viewing, the second, with a helmet-mounted display (HMD). These experiments are designed to assess the subject's stereoacuity in an alignment task involving two rods, one mobile, the other fixed. In both experiments, the subject has not time constraints and simply has to perform the task as well as possible. The dependent variable is the depth positioning error. Ten subjects with a stereoacuity of 20 arc-seconds or less and 20/20 visual acuity (Snellen test) corrected or not took part in this study. In all experiments, the subject was exposed to four viewing conditions in direct view or HMD: mono-stationary, stereo-stationary, mono with motion parallax and stereo with motion parallax. The independent variables are the presence of stereo (with vs. without), the presence of motion parallax (with vs. without) and the session (session 1 or session 2). ANOVA 2 X 2 X 2 statistical processing is used.
