Agenda Welcome to the Mobile World ● Mobile 1.0: when the story began – Mobile 2.0, Mobile Web 2.0: where we are today – Towards the Internet of Things! ● Mobile Tagging – Physical Tagging ● Tag the World! (Near-Field Communication) ● Everybody is a sensor – Get your own live lab: Sun SPOT – Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Mobile 1.0? 2001: testing LBS with state-of-the-art devices ● Two persons (FOUR HANDS!) to carry and keep connected PDA, GPS and GSM phone Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Mobile 1.0 was... ... an attempt to bring the Internet on mobile ● phones: WAP Sites Traffic Info M-Commerce Weather Info Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

From Web 2.0 to Mobile 2.0 The “2.0” (r)evolution meets mobile computing. ● Wireless devices are changing the way they enhance user's mobility: mobile browser --> mobile blogger data provisioning --> mobile data provider network-aware --> context-aware stand-alone --> augmented environment yet-another-device --> my constant touch Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Mobile Web 2.0: where we are today Constant touch with the world (RSS, widgets) ● Location awareness ● Mobile blogging, mobile data provider ● Mobup Where.com Mobile Web Toolkit Mobease and Webwag Mobile widgets Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Mobile 2.0 is... ... good balance between data provisioning and ● data providing on mobile devices: Web, Feeds Blogging Multimedia Photo post ... it's not enough! Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Towards Internet of Things New generation of devices and applications is ● based on massive use of sensors: Camera – Photo (we all want Mobup!) ● Tag recognition ● GPS – Location, speed ● Accelerometer – Device orientarion ● Gesture control ● NFC – Recognize and annotate objects ● Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Physical tagging (ShotCode BeeTagg QR) Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

The (r)evolution is TO WRITE Physical Tagging is a “read-only” approach: we ● can read tags but we still feel “passive” respect to the object What happens if we can write tags? ● Applications: ● voting on-site, voting on-object – book annotations – anonymous booking – Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Near Field Communication The NFC is a standard technology for secure, ● short-range radio frequency communication Tags contain up to 8KB, ● with read/write access Applications: ● instant ticketing by touch – gate & access control – write-on-objects – Nokia has released world first mobile phone ● compatible with new Contactless Communication API (model 6131 NFC) Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

The web looks at the real world Brutal attack: to have lots of connected sensors ● placed everywhere to let the web look at the real world. Is it feasible? Definitively NO! We don 't need to place sensors! We have ● already them! We are surrounded by many “small thinking and sensing machine”: they have just (!) to be connected each other and find a bridge to the Internet. Pervasiveness of the net becomes a reality if ● technology is really simple and cheap enough to let everybody partecipate, test, play, enjoy!

Everybody is a sensor! :-) Web, Feeds Blogging SensFeed? Env Data Multimedia Photo post Sensors ENVIRONMENT Now it's enough! Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Sun SPOT: get your own live lab! Sun SPOT is a powerful technology for wireless ● sensors network based on the Java ME platform It provides: ● programmable modules with sensor board – Accelerometer ● Temperature sensor ● Light sensor ● 8 tri-colour LEDs ● A/D input ● GPIO pins ● Modules can use PC to ● connect to the Internet! Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Sun SPOT under the hood Hardware ● 180MHz 32-bit ARM 920T CPU – 512Kb RAM, 4Mb FLASH ● Chipcon 2420 radio package – 2.4GHz, IEEE 802.15.4 (as ZigBee) ● 3.7V 750 mAh Li-Ion battery – Power consumption 40-100mA ● (40 uA deep sleep) Software ● Squawk Virtual Machine (no Operating System) – JME CLDC 1.1, IMP and additional libraries for – specific functions such as sensors, radio...

Conclusions Convergence of Web 2.0 and mobile is here! ● Next revolution is just around the corner if... ● everybody can contribute with new, – unpredictable ideas hardware and software are cheap and open – interoperability is real, not just on specifications – regulations let people freely use any short- – middle range radio See you next year, with your own “things” :-) ● Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007
