A safe driving support method using olfactory stimuli

Abstract

Recent progress of IoT technology becomes remarkable and driver monitoring systems with in-vehicle devices is one of promising application field. In this paper, we propose a method for constantly monitoring a driver’s line of sight and warning him/her by sound and scent when it detects a dangerous state due to inattentive driving. Sound is an effective method for instantly alerting some state, but it may become a factor for hindering the driver’s concentration. Therefore, we devised a method for gently presenting the warning as a background information by scent. We developed a driving simulator and conducted experiments for verifying the effectiveness of the proposed method.
