Low-Cost Malleable Surfaces with Multi-Touch Pressure Sensitivity

While touch sensitivity has today become commonplace, it is oftentimes limited to a single point of contact with a hard, rigid surface. We present a novel technique for the construction of a malleable surface with multi-touch sensitivity. The sensor is pressure sensitive and responds to near zero-force touch from any object. The technique is an extension of previous work based on frustrated total internal reflection.
