Pattern identification on a fingertip-scanned electrotactile display

摘要

Six subjects participated in a study to determine their ability to identify simple geometric patterns on a 49-point fingertip-scanned electrotactile display and on an array of Braille-like raised dots. While the raised dot performance (97.2%) was better than the electrotactile performance (78.5%), this study represents the first successful demonstration of electrical stimulation of tactile patterns on the fingertips.
