questionnaire. The evaluation task is to ask for
opinions about the system’s effectiveness. The
question is given: “What impression do you receive
after using the stamp?”
3.2.3 Procedure
We have conducted semi-structured one-on-one
interviews, just after the Stamp-On system
experiment. The interviews takes approximately 5
minutes per participant.
3.2.4 Results
Table 2 shows the results of the interview-based
survey. Firstly, positive answers (‘interesting’, ‘fun’)
are obtained from the participants. Some participan
emphasizes the significance of the interface when
they stand in front of the rocks, the exhibit, and
pressing the stamp on the device. The following
statements are given by them: “With the stamp, I
always stand in front of the rocks,” “Actually
touching the rock and then pressing the stamp is
easy to understand.” They indicate the stamp’s
potential as an effective intermediary between a
child and an exhibit.
4 CONCLUSIONS
This paper has describes the design principle of
Stamp-On system and its preliminary experiment.
The Stamp-On system is characterized by a tangible
interface in a stamp form, which is easy to use.
Results of the experiment have shown that the
Stamp-On system is an attractive and effective
learning aid for school children at a museum.
Our future work include the improvement of the
interface focussing on the stamp, further
experiments with school children, and development
of new contents and support functions for a variety
of visitors.

Table 2: Participants’ replies in the interviews.
Participant A:
Firstly, I thought the system was interesting and
fun. Pressing a stamp on something, that kind of thing
is enjoyable. I think it is great that there are
movements involved, it will keep children interested
and I thought that it was enjoyable.
The important thing is that you have to stand in
front of the rocks to be able to do it, is it not? When
you use a finger, you can just tap anything while
looking at the rocks from afar, but this system has a
definite advantage because with the stamp, you have to
stand in front of the rocks and press it on the device.
Participant B:
Pressing a stamp on something is something
children like, as well as me, so my impression of the
stamp was that it was an interesting idea. Actually
touching the rocks and pressing the stamp that is there
is easy to understand, I thought.
Because you want to get the questions correct,
something you would not be able to do unless you
observe it in more detail, I think that the quiz allows
for even more in-depth learning.
