内容記述 The present study investigates the efficiency of haptic search facilitated by the division of the searchable area. Previous studies have shown that scales pro-vided around tactile maps for blind persons can shorten the search time for tactile symbols on the maps. However, the optimal number of divisions that shortens the search time the most has not been found. We conducted the experiments in which tactile maps with five different numbers of divisions were presented to the sighted and blind participants. The search times for tactile targets on the maps were measured and a movie that recorded searching behavior was analyzed.
 In the first experiment, maps with different numbers of divisions were presented to 11 blindfolded sighted participants. The results indicate the 3 × 4 divisions minimize the search time, and the relationship between the number of divisions and search time was not monotonic. However, there were no significant differences in search time among the numbers of divisions.
 In the second experiment, same conditions were presented to 16 blind participants. The results indicate the 4 × 5 divisions minimize the search time, and the relationship between the number of divisions and search time was not monotonic. Contrary to the hypothesis, the search time in the 2 × 3 condition was longer than in the non-scale condition. This could be the participants searched the entire map carefully in the non-scale condition and that led to short search times, on the other hand they searched only the divided area that had the target in the 2 × 3 condition and failed. Then, they had to start over the search and that led to long search times. The median searching time over the 3 × 4 and 5 × 6 conditions had no large difference.
 These results are assumed that the effect of the divided area on efficiency of the haptic searching has a limitation from a certain size. Therefore, for the future prospect, we should conduct a study of the different sizes of tactile maps in order to reveal the relationship between search time and the size of the map. This finding should be utilized for the optimization of automated tactile map creation system.
