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

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
●

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)

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!
Mobile HW Mashup – Frontiers of Interaction III, Milan – June, 28th 2007

Everybody is a sensor! :-)
Web, Feeds Blogging
SensFeed?
Env Data
Multimedia Photo post
Sensors
ENVIRONMENT
Now it's enough!

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” :-)
