The Effects of Character Stroke Width on the Visibility of a Head-Coupled Display.
Abstract
Experiments on visual-vestibular interaction with head-fixed displays have involved many different display types. This experiment is one of a series directed toward obtaining systematic information of effects of display characteristics on visual performance when man is in motion. When man is required to view a head-fixed display during body movement, his reading performance is degraded because of inadequate suppression of the vestibulo- ocular reflex. An experiment has been conducted to ascertain whether visual performance can be enhanced if the characteristics of a visual; display are modified. Subjects were exposed to a 0.025 Hz angular oscillation about the yaw axis with a peak velocity of + or - 120 deg/s. During both the high and low velocity phases of the waveform there was a significant improvement in reading rate when either the stroke-width of teh character was decreased ot the inter- character spacing was increased. The results indicate that displays consisting of well-spaced characters composed of bright thin lines are the most suitable for use in vibration conditions.
