EMMA (2008)


Wearable Computing
Textile-based electro-tactile display

EMMA explores wearable electro-tactile displays to facilitate mobile alert with minimal distraction. The grid of textile-based electrodes is cross stitched with conductive thread and embedded in a wristband interface.

EMMA is designed to provide visual distraction-free alerts for mobile users. The highest resolution of EMMA corresponds to 14×14 pixels in 1 inch square. The experiment discovered desirable guideline for directional tactile pattern design by revealing important factors that affect human perception on electric tactile illusion on the wrist.

Design/Prototyping

Cross stitching with conductive thread, breadboarding, laser cutting, directional pattern design for tactile illusion

Implementation/Programming

Arduino, Java

Evaluation
