a Schematic illustration of TPIEA applied on the display panel. The device can transmit tactile information corresponding to the images displayed (Image source: Gettyimages). b Schematic image of a 10 × 10 TPIEA array divided for tactile mimicking corresponding to picture. c Color maps depicting the electrotactile sensation to be implemented according to the divided zones. d Confusion matrix result of 50 perception test trials corresponding to each electrotactile sensation. e Images of the rolling ball captured from video (Video source: Septadi, Adobe Stock). f Spatiotemporal color maps of the current density of tactile stimulation corresponding to ball movement in 3D. g Finger movements that follow the direction in which the ball is rolling due to the parallel change in electrotactile sensation implemented. h, Spatiotemporal color maps of finger pressure distribution applied to the display of an electronic device during finger movement.
