Abstract

A tufted controller using electronic textiles offers a unique way of controlling on/off and similar functions of electric and electronic devices. The uniquely soft and tactile tufted controllers offer relatively larger areas of more versatile contact over the prior art (i.e., flat, hard capacitive contact sensors). The tufted controllers may be constructed with yarn, string, thread, cordage or the like—even novelty yarns, like boucle- or eyelash type. Kits for building such controllers—especially for lamps and patches are popular craft projects.

Claims

1. A tufted controller comprising at least one continuous, conductive fiber linked to a flexible non-conductive support material by linking means, and an electrical connection element having two opposing ends and being connected at one end to said conductive fiber and at the opposing end to a capacitive sensing circuit.
