The very first version of this presentation, created in 2011, was first presented at Interaction12, Dublin. That conference led to the birth of my first book - "Designing Multi Device Experiences", by O'Reilly Media (http://amzn.to/1wcLa8d). Since 2011, this presentation went through multiple revisions and updates, and was presented in various events (including: UXPA Cleveland 2014, Tech Planet 2014, Seoul; SXSW V2V, 2014; Fluxible 2012, Waterloo; Smart Device & Mobile User Experience 2011, London).

8. We have entered a multi-device world
1.75 Billion smartphones users worldwide in 2014
24 Billion wireless connected devices in 2020
225 billion app downloads worldwide in 2016
6 Connected devices owned on average by tablet owners
86% use mobile devices while watching TV & using other media
90% move between the 4 core devices to accomplish a goal

9. To put these numbers in perspective
Connected devices already exceed the number of
people (and toothbrushes) in the world
Mobile app revenue reached $26 Billion in 2013.
$11.8 Billion would feed the world’s undernourished
Monthly app downloads figure is > 9 times greater
than McDonald’s sells burgers
According to World Bank estimation

 Experience is replicated across different devices in terms of
content, flow, structure & core feature set
 Some adjustments are made to accommodate device-specific
properties (Mainly – Screen size & Interaction model)

17. Can we go any further?

19. Consistent experience provides access to
everything, anywhere, anytime
But overlooks:
• Context
• Multi-device relationships
• Best (available) device
• Scaling to a connected world (IoT)
