We demonstrate Stick&Slip, an approach that alters friction between the fingerpad & surfaces by depositing liquid droplets that coat the fingerpad. In our recent publication, we found that liquid coatings can modify the finger’s coefficient of friction, allowing users to feel surfaces up to ±60% more slippery or sticky. Unlike traditional friction-feedback, such as electroadhesion or vibration, our approach: (1) alters friction ona wide range of surfaces and geometries, making it possible to  modulate nearly any non-absorbent surface; (2) scales to many objects without requiring instrumenting the target surfaces (e.g., with conductive electrode coatings or vibromotors); and (3) both in/decreases friction via a single device. We demonstrate Stick&Slip in a mixed reality experience with props.
