AbstractThere is a steadily growing number of mobile communication systems that provide spatially encoded tactile information to the humans’ torso. However, the increased use of such hands-off displays is currently not matched with or supported by systematic perceptual characterization of tactile spatial discrimination on the torso. Furthermore, there are currently no data testing spatial discrimination for dynamic force stimuli applied to the torso. In the present study, we measured tactile point localization (LOC) and tactile direction discrimination (DIR) on the thoracic spine using two unisex torso-worn tactile vests realized with arrays of 3 × 3 vibrotactile or force feedback actuators. We aimed to, first, evaluate and compare the spatial discrimination of vibrotactile and force stimulations on the thoracic spine and, second, to investigate the relationship between the LOC and DIR results across stimulations. Thirty-four healthy participants performed both tasks with both vests. Tactile accuracies for vibrotactile and force stimulations were 60.7% and 54.6% for the LOC task; 71.0% and 67.7% for the DIR task, respectively. Performance correlated positively with both stimulations, although accuracies were higher for the vibrotactile than for the force stimulation across tasks, arguably due to specific properties of vibrotactile stimulations. We observed comparable directional anisotropies in the LOC results for both stimulations; however, anisotropies in the DIR task were only observed with vibrotactile stimulations. We discuss our findings with respect to tactile perception research as well as their implications for the design of high-resolution torso-mounted tactile displays for spatial cueing.

Abstract The authors have developed tactile displays which have vibrating pins to convey the surface texture sensation of object surfaces to the user’s fingertip. The tactile sensation intensity scaling was performed to obtain a sensation scale of the display by means of the JND (just noticeable difference) method. One dimensional curves on the scale were displayed to investigate the human sensitivity to an intensity change rate. A tactile texture presentation method based on the image of an object surface is introduced. Two kinds of experiment were performed to discuss the feature of the method. Texture discrimination is the first one, in which the effect of texture element size to the correct separation was discussed. Then the sensations produced by the display and those by real objects were compared regarding several samples that had a major feature of vertical lines and of not containing low frequencies. The results are summarized, which is followed by the future research work.
