Abstract

The goal of this study is to evaluate the effectiveness of electrotactile feedback on the fingertips by examining how accurately different dynamic patterns can be perceived. We designed three pattern types (Single Line, Double Line, and Box) and programmed each to move in eight distinct directions: bottom to top, top to bottom, left to right, right to left, bottom-left to top-right, top-right to bottom-left, bottom-right to top- left, and top-left to bottom-right. A study was conducted to assess these patterns’ perceived accuracy and response time on fingertips. The study results revealed that the Single Line and Double Line patterns had higher recognition accuracy than the Box pattern. Participant feedback on the Box pattern was mixed, with some finding it useful while others struggled with tracking its movement. In contrast, Single and Double Line patterns received positive feedback. Based on these findings, a second study was conducted for walking conditions. In this second phase, the participants again showed higher accuracy and stronger preference for the Double Line pattern. Hence, we conclude that the Double Line pattern provides clearer and more reliable electrotactile feedback, even during movement.
