    Technical Textiles Technical Textiles Presentation Transcript

    • New Interactive Materials Matthew Chalmers University of Glasgow Cliff Randell University of Bristol
    • Technical Textiles
      • A lot of wearable computers fit the ‘boxes in pockets’ stereotype
        • Relatively unwieldy devices, hidden in pockets and linings
      • New textiles support sensing, display and communication
        • Conductive fibres for buses and antennae
        • Thermochromic/electroluminescent fibres changing colour
        • Shape memory alloys, muscle wires and tactons changing shape/pressure
        • Carbon-fibre stretch-sensing panels
        • Sensors of heartbeat and other physiological properties
      • Garments not (just) computers
        • Everyday use, wherever one goes, for communication and expression
        • On and about the body: digital as well as physical, intimate, cultural…
    • Initial Experiments
      • Electromagnetic field detection and screening
        • UHF (RF pingers, motes, Smart-Its) detectable at 14m
        • Radar frequencies: GPS (1.8GHz) and Bluetooth (2.4GHz) possible
        • Power levels of mobile phones (900MHz-1.8GHz) too strong
        • Various screening materials available commercially
      • Underlying backing for thermochromic textiles
        • Sensitivity of dye can be tuned to be in a small and safe temperature range
        • A safe voltage (20-25V) drove a 10cm length strip with a 31° transition
      • Conductors for electrical signals and power
        • 500mA, suitable for low-power sensors and microcontrollers and displays
        • Organza: can attach and drive LEDs directly
    • Prototype Components
    • Bristol Workshop, Dec 2004
    • Central Saint Martins
    • Ongoing Work
      • Making and experimenting with samples and components
        • Weaving conductive and EL fibres, stretch panels, pressure panels…
      • Connectors for the woven bus
        • Adding other larger components, e.g. Bluetooth comms
      • Contacts and welding
        • Discussion with The Welding Institute, Cambridge
      • The AHRB/EPSRC Emotional Wardrobe cluster
        • First design workshop on March 9th
      • Seamful Games
        • Dark Bill: one jacket per player
        • Small numbers of prototype garments in a larger game setting
    • Conclusion
      • Technical textiles
        • New materials affording sensing, display and communication
        • Artefacts that are most digital as well as physical, intimate, cultural..
        • Opening up a design space through experiments, prototypes & workshops
      • Garments as part of wider user experience design
        • Combining two mass media: computing and clothing
        • Seamful Games: showing state and sharing status in multiplayer games
        • Emotional Wardrobe: emotional communication between lovers, family…
