This paper introduces a handy haptic device which informs users about analog information by different vibration. Human's subjective recognition to same stimulus varies from different external condition, so vibration alert interface is effective for information calibration by pulsing different vibration signals. Above all, the author explains the main function, internal components and working environment of Vibration Alert Interface. After, the author supposes a mathematical model to describe relationship between vibrotactile perception and interval period according to associated equations. Then author conducts a series of experiments and verify those assumptions and discover some other property of effective elements of interval period.
