Eslucent is an on-skin wearable capacitive sensing device that affords blink detection, building on the form factor of eyelid stickers. It detects blinks during intentional blinking and four involuntary activities by a falling edge detection algorithm in a user study of 14 participants. By embedding interactive technology into a daily beauty product, Eslucent explores a novel wearable form factor for blink detection.

Eslucent is an eyelid on-skin interface for tracking eye-blinking. (a) The on-skin interface consists of 6 layers. Each layer is shown individually, layered on top of each other. The color of Esculent can be customized, for example, with (b) silver and (c) black eyeliner.
