Development of a one-dimensional lateral tactile display for the sensation of texture using a speaker array

Abstract

We report the development of a tactile display made from audio speakers and aluminum plates and having high spatial and temporal resolution. Aluminum plates with thickness of 0.5 mm are attached to audio speakers and aligned at intervals of 1 mm, and skin is deformed perpendicular to the plate direction. The device presents skin deformation with a wide frequency range (10–320 Hz) when a finger is placed on the plates.
