High Spatial Resolution Midair Tactile Display Using 70 kHz Ultrasound the conventional 40 kHz ultrasound tactile display. Since the focal spot diameter was smaller than a finger pad, the user could perceive a localized spot on the finger pad. In the experiment determining the physical properties, we found that the ultrasound attenuation at 70 kHz was comparable to th

Weight and Weightlessness Effects on Sensorimotor Performance During Manual Trackingtwo-dimensional tracking tasks with a joystick. Results indicated that extra arm weight did not decrease tracking performance, but decreased acceleration variance. In weightlessness, tracking performance decreased and the control of movement impulses was deteriorated. This result pattern was found d

Shape Features of the Search Target Modulate Hand Velocity, Posture and Pressure During Haptic Searcion of different primitive shapes. In our experiment, blindfolded sighted individuals were asked, firstly, to learn a complex search target and, secondly, to find this search target embedded in a larger, encompassing search field. Our goal was to examine, how different shape characteristics of the c

The Influence of Motor Task on Tactile Suppression During Actiontactile suppression likely interferes with performance in motor tasks that require the precise evaluation of tactile feedback, such as the adjustment of grip forces during grasping. Therefore, we hypothesise that suppression might be stronger for stimuli that are irrelevant to successful performance
