Abstract
This presentation outlines a novel method called virtual light touch contact (VLTC), which helps to mitigate postural sway of the human body during walking. The method involves setting a virtual partition around the user and estimating the virtual force caused when the user touches it. A prototype system was developed using motion-capture system and a vibrotactile stimulator, and experiments involving young healthy subjects were conducted during periods of walking. The experiments showed that the RMS of acceleration for VLTC was lower than for normal walking. These outcomes suggest that the VLTC method helps to mitigate body sway and is therefore useful for walking support.
