Analysis of Questionnaire

Part of the experiment was the questionnaire, focused on participants personal

opinion about presented maps. The questionnaire was presented after all stimuli,
and it contained only two questions. First one concerned the suitability of the map.
Respondents were asked to answer, which variant of the map was more suitable for
finding the answer. Second question was focused on the aesthetic factor—which
variant did they like more. In both questions, three options were available—“2D”;
“3D” and “Depends on the specific map”.
Participants found 2D map more suitable for answering the question (finding the
point symbol in the map) than 3D map. Majority of them (24 from 40) preferred 2D
variant of the map. Relatively high number of respondents (13 from 40) chose
answer “Depends on the specific map”.
