Fiber has been given the external meaning of emotional communication. In the Mobile Internet information age today, people pay more attention to the exchange of information through the appearance characteristics of the fiber. In this paper, we introduce the interactive information sensing technology to fiber research and development. We attempt to improve the interactive sensing initiative of the fiber itself by integrating the following three parts. The first is the design of external shape and the forms of interactive information of the fiber; the second is the hardware design of interactive signal collection, power management and true color LED elements; the third is the software development of sound, temperature, distance and other environment detection modules.
