Abstract
The cognitive rate offour levels of hardness was experimentally examined in ten normal volunteers with actual object as well as virtual object displayed by a glove-shaped force display, in order to discuss the role of visual, tactile and proprioceptive sensation in cognition of the hardness of an object. The experiment was carried out under five conditions as follows, 1 ) actual object; 2) actual object without tactile information about the object deformation; 3) actual object without proprioceptive information; 4) virtual object using a force display and 5) virtual object with visual information. The cognitive rates were 94, 82.8, 92.6, 83.6, 90.4%, respectively. The role of visual information was greater than proprioceptive information, however less than tactile information. A method to enhance the hardness display performance by alternating the visual information was proposed and its effectiveness was shown experimentally as the increase of the hardness cognition rate from 90.4 to 93.0%.
