| Abstract(in English) | This experimental study examined the ability of people to perceive the hardness of an object solely through the tapping sounds of a white cane using a method of magnitude estimation. The results showed that both sighted university students and totally blind participants were able to accurately judge the hardness of an object solely by using auditory information from a white cane. For the blind participants, different handgrips significantly influenced the accuracy of their estimation of an object's hardness. The results of frequency analysis indicate that the high frequency components related to the hardness of an object when tapping because the high frequency component of the tapping sound increased as the hardness became higher in all conditions. |
