Correction Method Based on KI-VPA Model for Changes in Vibratory Perception Caused by Adaptation
This paper describes a method for correcting differences in human vibratory perception caused by sensory adaptation. Humans feel a vibrational strength when a vibrating device is held in the hand. However when the vibrational frequency is changed, human perception of the new frequency is affected by the vibrational frequency experienced before the change. This is called sensory adaptation. The Katagiri–Aida model-based vibratory perception adaptation (KI-VPA) mode can estimate changes in vibratory perception caused bt adaptation. We have developed a correction method on basis of the KI-VPA model and tested the method on ten human subjects. The results indicate that the proposed correction method reduced the effects of adaptive changes to vibratory perception.
