State of Mobile / Air Graffiti

State of Mobile/Air GraffitiKristof Michiels, IBBT-SMIT, iLab.o, Vrije Universiteit Brussel

Hello!

Kristof Michiels = Researcher and application developer IBBT/SMIT/iLab.o, Vrije Universiteit Brussel Art History/ICT by formation ‘Rapid prototyping’ context-aware social media apps Focus on mobile, web, city, arts, e-culture

Some examples: Air Graffiti / Wayfinding 2.0 / Edosia.org

My presentation

Mobile devices / Multi-modality

Ways to interact with the physical world / Context

Ways to interact with the physical world / Objects

An example / Air Graffiti


Problematic for years: Technology not ready (think

WAP, battery life,…) Lack of mobile broadband access Lack of users & applications

(chicken and egg problem)

Current situation: Lack of user adoption compared

to fixed internet Price of mobile broadband

[abroad],…) But: new gen. of mobile

devices/platforms / driver of social media

But: new generation of mobile devices-platforms that actually “work” / Social media, web2.0


Take-off: not as fast as some would lead you to believe, but: YES

iPhone/iPod Touch: real take-off of mobile apps

Apple sold + 40 million devices (sep ‘09) 21 million iPhones 20 iPod Touches

Application store, in less than 1,5 years, counts +100.000 applications

+2 billion applications have been downloaded

People are really using it!

iPhone: Real take-of of mobile applications

Still: heterogenous landscape Web applications vs ‘Native

applications’ E.g. Android OS (Google)

Social Media: important driver!

8

Web 2.0: made us use the web as a realtime and always-on medium

People want access wherever they are / Facebook, Netlog [youngsters]

Social Media: important driver!

Museums on Twitter: twitter.com/admkrm/museums[2]

Mobile applications can live inside existing platforms

New generation of mobile museum applications

Love Art: National Gallery, London


Yours, Vincent The Letters of Vincent Van Gogh


Brooklyn Museum Mobile Collection


Versailles, Lonely Planet Paris City Guide, Marco Polo City Guide Paris


Don’t forget Podcasts !


Even new generation of mobile museum apps do not change the current paradigm / are like mobile audioguides people bring themselves / one-way #fail

Mobile 2.0 = Everywhere + always + personal = everyware Social Context, location, presence Bridge physical-virtual world gap

Are museums 1.0 ready for Web 2.0 ? Even youngsters: Nintendo Wii & DSi, Sony PSP [high

expectations!]

BANKSY: “A small group create, promote, purchase, exhibit and decide the succes of Art. Only a few

hundred people in the world have any real say. When you go to an Art gallery you are simply a tourist

looking at the trophy cabinet of a few millionaires.” (Banksy.co.uk)

Real ‘social media’, allow real ‘participation’ ???

My presentation





Interacting with the physical world / Context

GPS

Bluetooth

QR (2D-barcodes)

RFID

“LPS”

How can applications learn about the context of the user?

And learn about the location or the presence of an object?

GPS

Most current smartphones have GPS / outdoor only!

GPS and augmented reality (AR)

Layar.com

Bluetooth

Example Antwerpen, Kammenstraat (Belgium)

QR codes – 2D barcodes

22

Identification by taking a picture of a code

Radio Frequency ID chips (RFID)

Barcode system (1975) – 5 billion scans/day (2005)

Now: RFID / NFC Passive vs active Active: id broadcasting / scanning

own environment Acting dependent on its own context:

hiërarchic, coördinating, protecting, filtering, … [future]

Currently problematic: lack of end-user devices

‘LPS’ or Local Position System (‘check-ins’)

Foursquare.com, Gowalla.com, Brightkite.com

or: how to solve the indoor problem now

Other examples from our research

- Smart metering

- Floating vehicle data / Intelligent Transport systems (ITS)

- e-cube (autonomics)

- Sensor network Noise pollution

- Weatherlink

Object-generated content?

Interacting w objects / object-generated content

Objects are entering online space. This is the so-called ‘Internet of Things’

Just as their human counterparts (i.e. user-generated content) they will create content and meaning online

They will interact with other objects and humans (and vice versa).

In the beginning: simple interaction (through APIs / accessing metadata). Later: more complex forms of reasoning. Will be able to make ‘autonomous’ decisions.

Objects become “Spimes” (Bruce Sterling)

Artefacts – Machines - Products – Gizmo’s – Spimes Spimes = networked dynamic en context-aware

objects that keep track of their own history of use and interaction with their environment. Whole process is part of the object

What does it mean for a cultural and art institutions on the one hand & tangible heritage on the other hand when boundaries between objects, people, a setting become blurred?

My presentation





Air Graffiti = contextual content creation/consumption

Air Graffiti – Content creation

Anyone can add rich content objects to a certain context Fixed or mobile GPS ‘LPS’ qr-codes / RFID-ready


Content can be clustered into channels Explicitly Virtually (based on metadata, actual use, context) Channels can be structured (object 1 -> 2 -> 3) Appearance of channel is fully customizable


A simple set of rules can be added to each object 1. for whom is it visible? (the world, my friends,

channel members) 2. its broadcast range (2m, 20m, 200m,…) 3. its lifespan (1h, 1day, 1week,…) 4. prerequisite object

Air Graffiti – End-users

People can enter the application: Through current location (GPS, LPS): ‘radar’ view

like a facebook for objects Through an individual object or channel (GPS, LPS,

QR, RFID, Search or other object)


Can comment / create their own content No discrimination / we do have “verified accounts”


Smart context engine based on user behavior System keeps track of everything:

Objects you have consumed / the order… Objects you have ‘liked’ Locations you have visited Patterns of other users with similar interests

Provide recommendations and application flow Provides object-based navigation

Air Graffiti – Use Cases

Allows for complex, dynamic and highly personalised indoor and outdoor trails

Use cases: the city, the museum Guides, quests, storytelling Instant mobile application

Launch: November 30th 2009 / send an email = invitation when we launch
