Abstract:
The auditory-induced illusion called vection has been investigated for decades. However, it is not confirmed how the illusion affects to body balance. Especially, during a dynamic activity such as walking, it has not confirmed whether any clear effect to the body balance control appears or not. This paper focuses on investigating the effect of vection during walking. Especially this paper will discuss the space perception induced by acoustic stimuli that indicate the directions. The authors of this paper measured the response time from the acoustic cue to body balance control and the rotation amount using a small sensor system with accelerometer, magnetic and gyro sensors. According to the experiments with sight/blind participants from young to old ages, requesting them to walk to the directions of the acoustic cues with/without sight, the authors confirmed a close relation between the vision and the auditory of human during a dynamic activity.
