Abstract:
A user study was performed to evaluate the effectiveness of high detail
insets used with head-mounted displays. Ten subjects were given a simple
search task that required the location of identification of a single
target object. All subjects seven different displays (the independent
variable), varying in inset size and peripheral detail, to perform this
task. Frame rate, target location, subject input method, and order of
display use were all controlled. Primary dependent measures were search
time on trials with correct identification, and the percentage of all
trials correctly identified. ANOVAs of the results showed that the
insetless, high detail display did not lead to significantly different
search times or accuracies than displays with insets. In fact, only the
insetless, low detail display returned significantly different results.
Further research is being performed to examine the effect of task
complexity, and to reach a better understanding of the varying inset size
and level of detail.
