2. Laboratory for Interactive Computer Systems 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. Laboratory for Interactive Computer Systems 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.
