Abstract
We have conducted research to obtain fundamental knowledge of the exploration methods used to perceive the characteristics of an object through contact with a white cane. The research has enabled us to examine methods that enhance the accuracy of perceiving objects and the materials and design of a white cane. In this study, we examine whether or not the method of grasping a white cane affects weight perception, with 5 visually impaired people who use white canes in their daily lives as participants. The participants provide estimates for the magnitudes of six weights ranging from 500 g to 1,000 g in steps of 100 g. Results indicate that weight can be determined using a white cane, even though this method is slightly inferior to directly pushing the weight by hand. The weight perception obtained by employing a white cane is not affected by the manner of grasping the cane.
