Development of a Pitch Conversion Tactile Display With Spatial Resolution Higher Than Human's Two‐Point Discrimination Ability
Abstract
ABSTRACT In this paper, we have proposed a pitch‐converting mechanism to realize a tactile display with both spatial resolution and vibration stimulation, aiming to present fine texture to human fingertips. To optimize the design of the proposed tactile display, we proposed a theoretical model of the relationship between design parameters and vibration amplitude. Based on the results, we designed and fabricated the seven elements pitch conversion tactile display. In the prototype display, 15‐µm displacement was obtained at a voltage of 25 V, and independent drives of each diaphragm were demonstrated, respectively.
