Abstract

Raised striped-pattern has been used as a drawing expression of tactile guide map. We are lacking in quantitative data regarding raised striped-pattern for designing easily understandable tactile map. In this study, we investigated the influence of interstices among the lines on tactile discriminability of raised striped-pattern. Ten younger persons and thirteen older ones were asked to distinguish the surface roughness according to 4 categories by comparing 10 raised striped-patterns of different interstices among the raised lines, which were prepared on the basis of the results of previous study. From this study, we found that 5.0mm interstice was necessary for distinguishing different surface roughness and those older persons were somewhat inferior to younger persons in sensitivity of surface roughness.
