The Study in the Figure Recognition of the 2-Dimensional Figure when it is Rotated: A Study on the Visualization Obstacle - Part 2 -

本文データの一部はCiNiiから複製したものである。The purpose of this research is to clarify the figure recognition. It was measured by giving new students of the university the test of 2-dimensional figure, which is composed of a basic problem and a rotary one. The results are as follows; 1) when the 2-dimensional figure is rotated, the figure recognition takes 3 times as much as when not rotated; 2) even if the answer time takes 3 times, the correct answer rate of 21 questions in 25 questions decreases; 3) the recognition becomes difficult by rotating the figure drawn in a consecutive line; 4) when the complex figure is rotated, the detail cannot be recognized; 5) in case of the complex figure, the correct answer rate improves when the correct answer choice appears earlier in every choices
