Abstract
Monocular head-mounted displays (HMDs) will be a major tool for ubiquitous
computing. However, monocular HMD visibility causes a decrease in the light received
from the environment. Fluctuating light from the environment strongly affects the
visibility of images presented on the monocular HMD. In the present study, we have
studied a method for controlling HMD backlighting to improve visibility at the wearing a
monocular HMD under variable lighting conditions. Three backlight control patterns were
developed from Experiment I as psychophysical measurements, and their validities were
subjectively evaluated in Experiment II. The results suggest increased visibilities at
wearing a monocular HMD when controlling the backlight. Moreover, the rules for
backlighting control are based on psychophysical theory.
