1: Introduction Mark Billinghurst Director of HIT Lab NZ, University of Canterbury PhD Univ. Washington Research on AR, mobile HCI, Collaborative Interfaces More than 250 papers in AR, VR, interface design Sabbatical in Glass team at Google [x] in 2013 Hayes Raffle Interaction Research Lead, Google Glass PhD MIT Media Lab Ran a couple of companies Launched a few products Won a few awards Published many papers in HCI Major changes in computing How do you Design for this? Course Goals In this course you will learn Introduction to head mounted wearable computers Understanding of current wearable technology Key design principles/interface metaphors Relevant human perceptual principles Rapid prototyping tools Areas for future research Hands on experience with the technology What You Wont Learn Low level programming Glass Mirror API, GDK, Vuzix SDK, etc Designing for non-HMD based interfaces Watches, fitness bands, etc How to develop wearable hardware optics, sensor assembly, etc Evaluation methods Experimental design, statistics, etc Schedule 9:00 Introduction (Mark + Hayes) 9:05 Overview/History (Mark) 9:20 Evolution and Design Principles (Hayes) 9:45 Prototyping Tools + Best Practices (Mark / Hayes) 10:20 Break/Demo 10:30 Concept Design Exercise (Design group / Hayes) 10:50 Wearable Technologies (Lecture group / Mark) 11:20 Design Presentations (Design group / Hayes) 11:50 Research Directions (Mark + Hayes) 12:20 Finish Design Group (33 People) If your name is on this list you are in the Design Group Yang Wang Konstantino Kapetaneas Preethi Srinivas Tony James Kate Vogt Aneesh Tarun Josh Andres Maria Maim Bram Reurings Luke Mill Tuck-Voon How M Gill Janaki Kumar Melinda Knight M Calkins Mike Tissenbaum Samantha Tse Kal McDowd Adora Tam Oscar Meruvia Mike Chen Anita Hoechtl Merlin Stone Ashoomi Dohlakia Icy Zhu Zdenek Mikovec Cristina Manresa-Yee Christian Winkler Angela Noh Amyris Fernandez Deborah Ptak Arne Renkema-Padmos Thomas Fritz Display Demos You Can Try Google Glass Display Glass UI, AR demos, Games, multimedia capture Vuzix M-100 Display Monocular display Epson BT-100, Epson BT-200 See through displays, Junaio markerless tracking Brother AirScouter display Projected see-through image Recon Snow Micro-display integrated into ski goggles CHI Wearables Exhibit Online at http://wcc.gatech.edu/exhibition 2: Overview/History A Brief History of Time Trend smaller, cheaper, more functions, more intimate Time pieces moved from public space onto the body 18th Century 20th Century 13th Century A Brief History of Computing Trend Smaller, cheaper, faster, more intimate Moving from fixed to handheld and onto body 1950s 1980s 1990s Room Desk Lap Hand Head What is a Wearable Computer ? A computer that is: Portable while operational Enables hands-free/hands-limited use Able to get the users attention Is always on, acting on behalf of the user Able to sense the users current context Rhodes, B. J. (1997). The wearable remembrance agent: A system for augmented memory. Personal Technologies, 1(4), 218-224. In Other Words .. A computer that is .. Eudaemonic: User considers it part of him/herself Existential: User has complete control of the system Ephemeral: System always operating at some level Mann, S. (1997). Wearable computing: A first step toward personal imaging. Computer, 30(2), 25-32. Wearable Computing Computer on the body that is: Always on Always accessible Always connected Other attributes Augmenting user actions Aware of user and surroundings Augmented Interaction Rekimoto, J., & Nagao, K.

In Proceedings of the 8th annual ACM symposium on User interface and software technology (pp. 29-36). The Ideal Wearable Persists and Provides Constant Access: Designed for everyday and continuous user over a lifetime. Senses and Models Context: Observes and models the users environment, mental state, its own state. Augments and Mediates: Information support for the user in both the physical and virtual realities. Interacts Seamlessly: Adapts its input and output modalities to those most appropriate at the time. Starner, T. E. (1999).
