Abstract

We present Silicone iLluminated Active Peripherals (SLAP), a system of tangible, transparent widgets for use on vision-based multi-touch tabletops. SLAP Widgets are cast from silicone or made of acrylic and include sliders, knobs, keyboards, and keypads. They add tactile feedback to multi-touch tables and can be dynamically relabeled with rear projection. They are inexpensive, battery-free, and untethered widgets combining the flexibility of virtual objects with tangible affordances of physical objects. Our demonstration shows how SLAP Widgets can augment input on multi-touch tabletops with modest infrastructure costs.
