3.4 Experimental result
3.4.1 Assessment of gloss
Figure 3 shows an example of the results under the vision-only, tactile-only and
visuo-tactile conditions. The vertical axis is the average of the scores of the gloss
degrees with the kinds of black lacquer boards shown in the horizontal axis. The
error bars indicate the standard deviations. We obtained the following:
• The scores of B#10 and B#11 tended to be the same under the vision-only
condition.
• The difference between the scores of B#10 and B#11 under the tactile-only
and visuo-tactile conditions tended ...
