Description :


A Versatile Sensing Technique to Support Multimodal Flexible Surface Interaction

We present a multimodal on-surface and near-surface sensing technique for planar, curved and flexible surfaces. Our technique leverages temporal multiplexing of signals coming from a universal inter-digitated electrode design, which is printed as a single conductive layer on a flexible substrate. It supports sensing of touch and proximity in- put, and moreover is capable of capturing several levels of pressure and flexing. We leverage recent developments in conductive inkjet printing as a way to prototype electrode patterns, and combine this with a new hardware module for supporting the full range of sensing methods. As the technique is low-cost and easy to implement, it is particularly well-suited for prototyping touch- and hover-based user interfaces, including curved and deformable ones.
