Abstract
In this paper, vibration signals are investigated. Vibration signal is a vibration we use with special purposes or intentions. Vibration signal can transmit information to person through the sense of touch. Vibrators of portable phones are one kind of examples. The purpose of this study is to research on human sensitivity by vibration frequency, vibration pattern and parts of body that receive signals, and to propose the most suitable vibration signal for information. At First, 5 trial vibration signals refering to clock alarm, oven, rice cooker, and public phone sounds were made to find out the most conscious vibration signal. These vibration signals were evaluated by using SD method and the factor analysis. And, the clock alarm type vibration signal was obtained to be the most conscious vibration among the vibrations adopted in this report. Then this signal was modified and compared with the original one. The suitable vibration signal for forefineer was found.
