Description :


Expressive, Flexible and Silent On-Skin Tactile Interfaces

We introduce Springlets, expressive, non-vibrating mechanotactile interfaces on the skin. Embedded with shape memory
alloy springs, we implement Springlets as thin and flexible
stickers to be worn on various body locations, thanks to their
silent operation even on the neck and head. We present a
technically simple and rapid technique for fabricating a wide
range of Springlet interfaces and computer-generated tactile
patterns. We developed Springlets for six tactile primitives:
pinching, directional stretching, pressing, pulling, dragging,
and expanding. A study placing Springlets on the arm and
near the head demonstrates Springlets’ effectiveness and
wearability in both stationary and mobile situations. We
explore new interactive experiences in tactile social communication, physical guidance, health interfaces, navigation,
and virtual reality gaming, enabled by Springlets’ unique
and scalable form factor.
