The mean task environment setup times for the low complexity treatment
are 13.4 ( 
) and 14.6 ( 
) seconds for Elastic
Windows and independent overlapping windows, respectively. No
significant differences are observed for the low complexity treatment
( 
).
For the medium complexity treatment, however, subjects performs faster
with Elastic Windows ( 
).
For the high complexity situation, subjects performs about 4 times
faster with Elastic Windows ( 
) than with
independent overlapping windows ( 
)
seconds). Greater differences are found in the high complexity
treatment compared to the medium complexity treatment ( 
).
Figure 
shows the mean task completion times with
standard deviations marked as rectangles over the bars in the
chart. Minimum and maximum completion times are shown as a vertical
line over the bar. The three-way ANOVA statistics found no significant
difference related to interface ordering and task set differences at
all complexities.
