This paper describes perceived danger areas for backhoes. Two experiments were performed using a virtual environment system. The experiments assumed the scenes in which a backhoe was viewed from the front and the back. Twenty males, who have never worked at construction sites, served as the subjects. Logistic regression for repeated measures data revealed age and distance between the subject and the backhoe to be significant effects on danger or non-danger judgments for both experiments. Regarding the front view, the odds ratio for an increase of 1 m in distance was 0.05,and 0.91 for an increase of age range. The classification table showed a sensitivity of 0.9 for a cutpoint of 0.35 with an accuracy of 0.74. As for the back view, a sensitivity of 0.9 was achieved at a cutpoint of 0.2 with an accuracy of 0.7. Thus, the logistic regression analysis revealed that a sensitivity of 0.9 can be achieved with an accuracy of over 0.7 for both the front and back view of the backhoe.
