  • 1. CMU Wearable Computers and Pervasive Computing Asim Smailagic Institute for Complex Engineered Systems Carnegie Mellon June 28, 2001
  • 2. Approach
    • The three labs have collaborated in design and prototyping of more than 20 generations of wearable computers
    • Design and prototyping of complex systems require one interdisciplinary approach and multi-technology capabilities
    • Rapid prototyping, concurrent design methodology has been applied and refined.
  • 3. Complexity
    • The complexity of the prototype architects has increased by over two orders of magnitude, the total design effort has increased less than a factor of two.
    • Over five generations of wearable computers for speech recognition and translation, yielding 4.5 orders of magnitude improvement in performance.
  • 4. 1991 – 2001 Ten Years of Wearable Computing at Carnegie Mellon
  • 5. Wearable and Handheld Computers
  • 6. Production vest will go under “Float Coat”
