Abstract

Objective: Based on the two points threshold of vibration stimulation, this paper determines the vibration stimulation type and design variables of the Multi-sensing Vibration Interface. and performs the verification of whether it is compatible with the actual cognitive direction when directional information is provided to the wrist using Multi-sensing wearable device designed on the basis of these results.BRBRBackground: Most of the dangerous situations around us are accompanied by noise. However, pedestrians who are unable to use their hearing, such as hearing-impaired and distracted pedestrians, are unable to recognize latent danger with being exposed to major accidents. Therefore, there is a need for an intuitive and effective way to provide the direction of hazardous situations accompanied by noise to those who cannot use hearing.BRBRMethod: This paper consists of two experiments. In the first experiment, through the two-point threshold experiment of the vibration stimulation, the efficient arrangement of vibration stimulation of the multi-sensing wearable device and the type of providing the vibration stimulation were derived. In the second experiment, when direction information was provided to the user
