Abstract
We conducted cognitive research concerning the design of public information symbols for tactile perception. Offering element E, a curve C, a line L, as 3 attributes to 7 basic figures of line-drawing pictures, we analyzed by Multiple Regression Analysis how they were easy to understand for the Blind people with the simplified samples. As a result, we found that women, dogs and cars were affected by a line count, that children men and planes by a curvilinear count, and that deer by Element count, and we also knew the desirable degree of simplification by this research. Moreover to create more comprehensible design we have tried the design with higher theoretical figure. As a result, we have confirmed that high theoretical figure does not affect lucidity. According to the result of a general tendency through standardizing of data, the fact that a plus reaction has been made by increasing of both a curve and a line has been verified. The result of this research, hereafter, will be valuable as certain utility in the design framing of public information Symbols for tactile perception.
