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 1.0 was...

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

phones:

WAP Sites Traffic Info

M-Commerce Weather 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
●

Mobup

Where.com

Mobile Web Toolkit
Mobease and Webwag Mobile widgets

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!


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 Blogging

SensFeed?
Env Data

Multimedia Photo post
Sensors

ENVIRONMENT
Now it's enough!


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!

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...

Extreme Mash(ing)-up
Camera

WLAN ZigBee

3G

NFC

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” :-)
