not significant 1: Positive answer, 2: Neutral and Negative answer
participants responding with a 5 or 4 were classified
as positive respondents; participants responding with
a 3, 2, or 1 were classified as negative respondents;
and the number of each type of respondents was
tallied. We determined the statistical significance of
the deviation between the number of positive
respondents and that of the neutral/negative
respondents by using a 1 × 2 exact test.
The results showed no statistically significant
difference between the number of positive
respondents and the number of neutral/negative
respondents for one item (Item 6: Pin awareness
sharing operations were easy). The number of
positive responses trended higher for three items
(Item 5: It was easy to color-code problem
importance levels by pin color, Item 7: The
operation for discarding entered pins was easy, and
Item 8: The operation for changing the color
(importance level) of entered pins was easy), with
the difference between the number of positive
respondents and the number of neutral/negative
respondents being statistically significant at the 5%
significance level. For each of the other 11 items, the
number of positive responses trended higher, with
the difference between the number of positive
respondents and the number of neutral/negative
respondents being statistically significant at the 1%
significance level.
Table 2 presents a tally of the responses received
for the items about sharing of awareness about
manga frames and a compilation of the results. We
analysed the results using the same procedure used
for the usage and operation items, determining the
statistical significance of the deviation between the
number of positive respondents and that of
neutral/negative by using a 1 × 2 exact test.
As a result, for each of the 9 items (such as Item
14: Sharing awareness enabled us to discover
differences in awareness about manga frames and
Item 20: Sharing awareness enabled a lively
discussion in the group), the number of positive
responses trended higher, with the difference
between the number of positive respondents and the
number of neutral/negative respondents being
statistically significant at the 1% significance level.
4 CONCLUSIONS
The experimental evaluation results demonstrated
the following two points: (1) The system’s interface
has effective operation. (2) The system effectively
promotes discussion based on shared awareness
about manga frames.
However, there is a need to improve the
convenience of the interface for the pin entry,
movement, and erasing functions. Specific changes
could include improving the response and mounting
a continuous operation method enabling flick-based
pin color selection and changes.
