  2. Mobile Computing Spectrum

  3. Example of a Wearable Computer

  4. Wearable Technologies

  5. Wearable Computing • Origins debatable • 1960s • Thorpe & Shannon • Objective to predict roulette • Odds improved by up to 44% • devices finally banned by Nevada State • Steve Mann • Father of wearable computing • MIT wearable computing project • In a nutshell - • conventional computing paradigms have failed and that another, namely wearable computing, is needed to "restore the technological balance between people and their environments"

  6. Definition of Wearable Computing • Three Operational Modes • Constancy • Augmentation • Mediation • Six Fundamental Attributes • Unmonopolizing • Unrestrictive: • Observable • Controllable • Attentive • Communicative

  7. Operational Mode: I Constancy The computer runs continuously and is always ready to interact with the user. Unlike conventional laptops and PDAs, it should not need to be explicitly turned on prior to use.

  8. Operational Mode: II Augmentation In contrast to traditional computing, wearable computing is based on the radical premise that computing is not the primary task. The assumption is that the user is doing something else and that the computer should therefore serve to augment the intellect or the senses.

  9. Operational Mode: III Mediation Wearable computing allows for a greater deal more encapsulation than traditional portable computers. For example, it could function as an information filter, thereby blocking out material that users do not wish to experience, for example, irritating or offensive advertising. Alternatively, it allows users to block or modify any information that could potentially leave their encapsulated space. Clearly, this makes a significant contribution to user privacy.

  10. Fundamental Attributes 1-3 • Unmonopolizing • The user is not cut off from the outside world as though in a VRML world. Computing is a secondary activity and should therefore enhance sensory capabilities and, if required, augment reality in some manner. • Unrestrictive • The user can do other things while using it. • Observable • The output medium is constantly perceptible by the wearer.

  11. Fundamental Attributes 3-6 • Controllable • The user can take control anytime he/she desires. • Attentive • The system is aware of the user’s immediate environment. • Communicative • The system can be used as a communications medium if required.

  12. Alternative Definitions "pursuit of a style of interface as opposed to a manifestation in hardware”, Starner, 2001. Augmented reality defining characteristic Kortuem, 1998 • Augmented Reality • Origins in the 1960s • 1990s a research field in its own right • Supplements the real world with objects that appear to coexist in the same space as the real world

  13. Ongoing Research • Networking Technologies • Personal Area Networks (PANS) • Wired & wireless • Textiles • Materials • Wearable sensors • Smart materials

  15. Recommended Reading • Mehmet Engin, Alparslan Demirel, Erkan Zeki Engin, Musa Fedakar, Recent developments and trends in biomedical sensors, Measurement, Volume 37, Issue 2, March 2005, Pages 173-188 • Thad Starner, "The Challenges of Wearable Computing: Part I/II," IEEE Micro, vol. 21,  no. 4,  pp. 44-52,  Jul/Aug,  2001

  16. Mandatory Exercise • Find a paper in a digital library (ACM/IEEE/Springer/ScienceDirect) that describes a Wearable Computing application. • Describe it in your own words: • Motivation • Design & Implementation • YOUR observations on the authors’ claims
