Abstract :
A new method is proposed to measure the useful field of view (UFOV), when one can recognize the objects by visual task. Since the distance from fixation point to target index is strength of stimuli, a procedure to measure the UFOV is discussed in this paper, where the psychometric curve is obtained by the statistical estimation using probit methods. An approximation by ellipse is also applied to formulate the contour of UFOV. The proposed method enables one to estimate the threshold of recognition with probability that means the recognition-probability-based UFOV.
