What it is
Wearable computing promises to transform how people interact with information, but conventional graphical user interfaces (GUIs) rely on planar, rigid displays that are incompatible with textiles, which are made of one-dimensional fibres, and existing flexible and fibre-based displays do not naturally provide the digitally addressable, high-throughput, information-rich interfaces that interactive GUIs require. The authors present a digital pixel fibre that integrates addressable pixels, a common interconnection along the fibre's propagation axis for scalable in-fibre circuitry, and a coaxial sensing layer for touch localization at the level of the fibre. Microelectronic components and a touch-gated resistive path system form a linear circuit that acts as both an interactive display backbone and a computational bus, while peripheral multimodal fibre sensors and actuators provide physiological, inertial, optical and acoustic input and output. Integrated into the forearm portion of a garment sleeve, the fibres form a GUI with a 96 x 54-pixel display, a 30-frame-per-second refresh rate and 8-bit colour depth. It supports dynamic graphics, integrated audio-video playback, wireless data exchange and interactive computing functions, while, the authors report, maintaining the flexibility, washability, breathability and mechanical robustness of everyday textiles. They present it as a scalable platform for intrinsically interactive textiles and a path toward garments that operate as fully integrated computational systems.
Why it matters
Fibres with addressable pixels, touch sensing and circuitry turned the forearm of a garment sleeve into a touch display of 96 x 54 pixels refreshing at 30 frames per second. Conventional graphical interfaces need planar, rigid displays that are incompatible with textiles, which are made of one-dimensional fibres; here each fibre's linear circuit serves as both the display backbone and a computational bus, and fibre sensors and actuators add physiological, inertial, optical and acoustic input and output. The sleeve supports dynamic graphics, audio-video playback, wireless data exchange and interactive computing with 8-bit colour, while, the authors report, keeping the flexibility, washability, breathability and mechanical robustness of everyday textiles.
