버튼의 크기·높이·간격에 대한 시각·촉각 차이역 연구

The purpose of this study is to present the physical criteria of the tactile identification element for the buttons commonly used in general electronic products. For this purpose, we investigated how the difference threshold of tactile perception differ according to the size, height, and spacing of the buttons. As a result of the study, when the visual sense is used for the button, the size of the button is about 0.3 mm, the size of the button is about 0.4 mm when the tactile sense is used, It can be seen that when the size difference of about 0.2 mm occurs, the difference is felt. In addition, the difference threshold in height for the tactile sense was about 0.31mm for the circular button and about 0.27mm for the square button. Both the size, height, and spacing of the buttons were found to be more sensitive to using the visual and auditory senses than to using visual or auditory alone. Both the size, height, and spacing of the buttons were found to be more sensitive to using the visual and auditory senses than to using visual or auditory alone. As a result of comparison , there was no difference in the difference threshold between the shape of the button (circle, rectangle) and the reference size (4, 6, 8 mm). Difference threshold between the senses, such as visual, tactile, visual plus tactile senses, and the difference threshold in measurement items such as button size, height, and spacing, were found to differ.
