Abstract

Haptic sensory data about the human head is crucial for the accurate configuration of wearable devices. Most scholarly research has focused on the arms and back because these areas are easy to provide haptic stimulation, while it is more difficult to provide haptic stimulation on the head, so there are few studies on the head. In our experiments, we placed vibration motors on subjects’ heads for the first time to provide vibration stimulation and chose a continuous stimulation method to find out the absolute and differential thresholds of head haptics. In this study, we determined the absolute and differential thresholds of haptic in different regions of the human head. The results showed no significant difference in absolute and differential thresholds between the left and right regions of the temporal part of the head. The temporal and frontal regions of the head were significantly more sensitive to vibration stimulation with lower absolute and differential thresholds, and the top of the head was less sensitive to stimulation with higher absolute and differential thresholds. Differential thresholds for the head increased with increasing stimulus strength.
