Dilemma: porceddu or mobile devices?

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 1.0?

Two persons(FOUR HANDS!)

to carry and keepconnected PDA,

GPS and GSM phone

● 2001: testing LBS with state-of-the-art devices


Mobile 1.0 was...

● ... an attempt to bring the Internet on mobile phones:

WAP Sites

Weather InfoM-Commerce

Traffic Info


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 Web 2.0: where we are today

● Constant touch with the world (RSS, widgets)● Location awareness● Mobile blogging, mobile data provider

Mobease and Webwag Mobile widgets

Where.com

Mobile Web Toolkit

Mobup


Mobile 2.0 is...

● ... good balance between data provisioning and data providing on mobile devices:

Web, Feeds

Photo postMultimedia

Blogging

... it's not enough!


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


Physical tagging (ShotCode BeeTagg QR)


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


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)


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

Photo postMultimedia

Blogging

Now it's enough!ENVIRONMENT

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 toconnect to the Internet!


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” :-)
