  11. 11. This presentation was made possible by reading the following books. Special thanks for Joe Friel’s various publications which are not only extremely well organized and written, but for being true life-changing inspirations.
  12. 12. Below are links to various research papers, and articles found online. 
 The optimum finger spacing in human swimming ~ Alberto E. Minetti a,︎, Georgios Machtsiras b, Jonathan C. Mastersc Influence of different footwear on force of landing during running ~ Cheung RT1, Ng GY.
  13. 13. spending most of my time identifying, analyzing and experimenting with sports, fitness, health wearables technologies and services. As a consumer, wearer and analytical engager of wearable apps, my love of this ever- evolving technological bracket is not only my career, it is my lifestyle. I live, breath, eat (and run, swim, bike, for that matter) wearables, making me the ideal candidate to translate the use of wearables from the idea, to the production, to the marketplace, and ultimately into the user’s psyche. 15+ years building innovative content monetization services exploiting the magics of User Experience (UX), Analytics and Content Management Systems (CMS) for Universal Studios, Technicolor, Harris Corporation and customers such as Amazon, AT&T, Disney and South Korea Telecom. For years I have been designing B2B and B2C solutions to provide customers with the best entertainment experience by consuming the right movie or music track at the right time and on the right device. Finally, it was time for me to shift from building entertainment to building life-aspiring experiences. Since then I’ve been Guillaume Tourneur - Digital Product Manager
