Objective Evaluation of Obstacle Perception Using Spontaneous Body Movements of Blind People Evoked by Movements of Acoustic Virtual Wall

Figure 4

Distribution of the “SDs of the body movements” and the “maximum value of the correlation function.” The horizontal bar graph above the distribution graph illustrates the average and standard deviations of “the SDs of body movements.” The vertical bar graph at right of the distribution graph shows the average and standard deviations of “the maximum correlation functions.”
