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.
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.

Context Aware Computing• Knowledge of the user’s context
– Location
– Orientation
– Audio samples from the user environment
– Static data
• Context sensitive help– Proactive smarter assistant offering useful
information (whispering in your ear)
• Multiple sensors can be used to infer user’s intent– Wireless Card, Digital Compass, Thermometer, Camera

Virtual Whiteboard Architecture Overview
Service broadcasts received coordinates to all clients via CMU’s Wireless Andrew
Client sends a user’s drawing to the service as a series of coordinates
Clients draw received
coordinates on screen; all
clients are synchronized

Collaborative HelpThe labs have supported additional activities on
campus
• Electronic design in robotics projects
• Use of fabrication machines
• Interaction Design Studio helped other projects
• Multi-departmental projects
Formalize, advertise and open all these capabilities to other projects in ICES and CIT.
