Technical Textiles Presentation Transcript

  • 1. New Interactive Materials Matthew Chalmers University of Glasgow Cliff Randell University of Bristol
  • 2. 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…
  • 3. 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
  • 4. Prototype Components
  • 5. Bristol Workshop, Dec 2004
  • 6. Central Saint Martins
  • 7. 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
  • 8. 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…
  • 9. Thanks

    • U. Bristol: Henk Muller, Ian Anderson and Angus Clarke
    • Central Saint Martins: Sharon Baurley, Philippa Brock and Lisa Stead
    • EPSRC/AHRB Emotional Wardrobe cluster
      • CSM, U. Glasgow, Vodafone, HP Labs, KCL, RCA, Imperial, U. Bradford, TechniTex
