This document discusses trends in mobile, IoT, and the web. It begins by outlining the evolution from analog to digital phones to smartphones and virtual devices. It then covers the rise of connected things through IoT. It proposes that half of connected devices will be small IoT devices. The document considers bringing small devices into the web ecosystem and the characteristics of small connected things, proposing a simple WoT architecture without presentation layers. It also discusses the evolution of web UI/UX from keyboards to touch and NUI, and new APIs that enable hardware and sensor access. Finally, it envisions future speech applications and moving from multi-screen to non-screen multi-device contexts through rule-based and context-based invisible webs

More things are connecting to the Internet than people — Cisco’s Internet
Business Solutions Group (IBSG) predicts some 25 billion devices will be
connected by 2015, and 50 billion by 2020

But , Web Technology for Small Connected Things ?
Half of connected devices will be small IoT devices
(how we can bring those devices into the web ecosystem)
We need to consider
these small devices

Characteristics of Small Connected Thing
 Connectivity
 Locally, Globally
 Wired, Wireless
 Controllability
 One way, Two way
 Immediately, …
 Interactivity
 Interaction ability – screen, sound, light …
 Limitations
 Low Computing power
 Device capability
 Non-screen
