LightCloth is a new fabric interface that enables illumination, bi-directional light communication, and position sensing on a soft cloth. This cloth is woven from diffusive optical fibers. Sensor-emitter pairs attached to bundles of contiguous fibers enable bundle-specific light input and output. We developed a prototype system that allows full-color illumination and digital data input by infrared signals. This technology allows us to create new light-emitting fabric products that the user can edit its illumination interactively by pen input.
