We focused on the way in which 3-D reversible perception
from 2-D line drawings depends on gaze point and angle of drawings. Given this
consideration, we measured interpretations of subjects for reversible depth
perception (1) when they gazed at different gaze points and (2) when they saw
the different angles of drawings. The result is that both the first gaze point
and the presentation angle affected 3-D perception. Then we define sensitivity
vectors of the depth, and then apply these vectors to our results of
measurement. The interpretations using these sensitivity vectors agree with the
results of measurement.
key words: depth perception, first gaze point, reversible figure, sensitivity vector of depth
