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.

ApplicationsA number of previously untried application areas introduced.

-Maintenance, Inspection-Repair, Troubleshooting -Augmented Manufacturing -Plant Operations-Real-time Speech Translation-Navigation-Context-Aware Computing-Collaboration-Ubiquitous Computing-Telematics


11

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


12

PhD Features and Interaction

User’s List:• Items can be added,moved, and removed• Only “checked” items appear on the map

Description:• Information on the currently selected item • Dynamic information automatically updated

Map:• Dynamic information automatically updated

Map Controls: Zoom & Pan

Virtual Whiteboard Supports Design Meetings

• Menu Commands– Session management

– Geometric tools

– Expandable plug-ins

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


15

ClientsThe clients have included:

-NSF, DARPA, ONR-Boeing-Adtranz-U.S. Air Force-U.S. Marine Corps-Lockheed-Martin-IBM-Chevron

-General Motors-Daimler-Benz-Compaq-Shell-AT&T-Intel-General Dynamics

Electric Boat


16

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.


17

Awards

Three prestigious international design awards have been received:

• VuMan 3

• MoCCA

• Digital Ink


18

Visionary Research Projects

• Aura: Pervasive Invisible Computing

• Handy Andy Ubiquitous Computing

• Context-Aware Computing

• Augmented Reality


19

Goals• Provide expertise in interdisciplinary design, rapid

prototyping and user evaluation• Promote more interdisciplinary design projects• Provide methodology, measurements, and tools to

support and teach these methods and to support design meetings

• Provide a physical space and equipment to support design and fabrication

• Study interdisciplinary design through practicing it• Develop a metric to compare the prototypes and show a

performance increase by several orders of magnitude.• Educational support


20

Research Directions

• Pervasive Computing– Invisibilty, Minimizing User Distraction– User / Virtual Information Space Interaction– Enhance Human Capabilities

• Context Aware Computing• Visionary Interaction Design • Rapid Prototyping of Artifacts Involving

Multidisciplinary, Multi-technology Approach


21

Research Directions

• Near Zero Energy / Weight / Volume Wearable Computers

• Quick Evaluation Methodology

• New Areas and Applications– New Technologies– New Modalities of Interaction– Help for Elderly – Medical Applications
